المستخلص: Face recognition plays an important role in many applications like security, banking, access to buildings, and surveillance …. etc.Because of the face image can significantly change due to changing in some factors, such as lighting conditions, facial expression, and others factors, therefore face recognition is still a challenging mission. Useful properties of the Contourlet Transform (CT) are exploited in this thesis to investigate more discriminant features to enhance the face identification performance. In this thesis, a face identification system is suggested based on CT, and Multi - Layer Neural Network (MLNN) Classifier. The main reasons behind using the CT are : First, the CT supports progressive data compression/expansion, hence it is used for image compression. Second, the features in human face are not just horizontal or vertical. CT is utilized for feature extraction because it is a genuine 2D transform that can capture the edge information in all directions. After decomposing an image by CT, low and high frequency coefficients of CT are calculated in different scales and various angles. Most significant information of faces is contained in coefficients, which is important for face identification. The frequency coefficients are utilized as an input feature vector for a neural network classifier. Simple feed forward MLNN neural network is used to achieve the identification process. The network parameters are tuned to optimal values, in order to produce fair comparison between different types of feature vectors. To evaluate the algorithm performance, seven standard databases, and a proposed database are used. Some of them are of high variability, to examine the algorithm robustness against variability. In addition, the proposed algorithm is also evaluated using a generated database composed from five databases. Then the suggested method is compared with other classical feature - based methods such as, wavelet, Principle Component Analysis (PCA), and CT - PCA. The results indicate that the CT - based method has better identification (ID) rate, and is faster than the Wavelet - based and the PCA - based methods. This is due to the high sparsity of the CT and its efficient capability of compression. The ID rates obtained for a tested databases are Japanese Female Facial Expression (JAFFE) database (100%), face 94 database (99.34%), proposed database (98.55%), ORL database (96.5%), Senthil database (92%), Yale database (90%), FERET database (76.2 %), and FEI database (72.57 %), and comparing with other systems, an average identification rate 90.64% for the CT, 85.71% for the Wavelet, 53.92% for the CT - PCA, and 46.7% for the PCA for all tested databases.Moreover, the characteristics of low and high frequency sub bands a are studied with their effect on ID rates. The simulation results indicate that the best identification rates are obtained when using only the low frequency sub - band for all tested databases

المستخلص: في السنوات السابقة، زادت اهمية تحسين النظام الكهربائي. وان ثبوت التردد هو واحدة من الاشياء التي اثرت في خصائص النظام الكهربائي هي ثبوتية التردد. ولهذه الغاية، وحدة التوليد ملحقة بمسيطر اوتوماتيكي على التردد اثناء تغيير الحمل (LFC) لتنظيم القدرة الفعالة | In recent years, the importance of improving electrical power has been increased. One of the things influenced the characteristic of electrical power is the constancy of frequency. To this end, the generator unit is equipped with an automatic load frequency control (LFC) to adjust the active power produced and restore the frequency and tie line power exchange to their nominal value.The total model of a hybrid power system has a high dimension. The classical design tools are inadequate to cope with all dynamic features. Artificial intelligence techniques are found to be a promising tool to optimally minimize the transient dynamics and control efforts in a load frequency control. This thesis shows the execution of various Artificial Intelligence techniques on the tuning of PID controller in a load frequency control system to compute the PID controller. The techniques of genetic algorithm technique GA, particle swarm optimization PSO and artificial bee colony ABC were applied on four areas, six tie lines power system. The dynamic model was formulated in state variables form. A comparison between these techniques with different performance indices was presented. Results of the test system 1 and 2 were computed and compared. They showed that in test system 2 the load frequency controller can chase the load fluctuation in a short time. The IAE performance index gives an optimum dynamic performance using ABC. From the outcomes, they show that the test system 2 outputs regarding settling time and maximum overshoot were the best performances.

The charger is the most important part of the solar system because the only limited - age part of this system is the storage batteries. Storage batteries are essential in all standalone PV power systems. Their efficiency and life time affects significantly the overall PV system performance and economics. The storage battery's effectiveness depends on the charging process. Hence, this thesis deals with the study, simulation and design of an intelligent charger fed by solar system due to the latest technologies.The developed charging method entitled "the decreased charging current based on state of charge" is adopted in this thesis to charge a lead - acid battery. The principle of decreased charging current is to make the real charging current as close as possible to the maximum acceptable current. The advantage of this technique is to mix between the rapidity of charging and prevents of the overcharging and generates gases.The maximum power point tracking (MPPT) technique is adopted to maximize the PV output power, whatever of the temperature and irradiation conditions. The design considers different operating conditions of load, battery state of charge (SOC) and ambient effect in order to achieve the best charging condition of the batteries and to be compatible with the user requirements. The flexible, simple and cheap design is the objective of this charger.This PV charging system is composed of a solar panel, lead - acid batteries, buck converter as power charging circuit and a microcontroller as a control unit.The simulation results are achieved by using Simulink Proteus Isis Professional software. These results demonstrated the validity of the proposed charging technique. The battery charger prototype was tested and the obtained results agree with those obtained from the simulation

In this study, developing a folded microstrip antenna based on a novel antipodal Vivaldi structure based metamaterial inclusions of single negative properties is proposed for wideband applications. Although, Vivaldi antennas show unlimited bandwidth, an acceptable directivity, small size, light weight and easy to fabricate, but, it suffers from low gain due to traveling surface waves effects and therefore, it cannot be embedded inside the integrated systems ,where, the radiation direction is in the end - fire that limits their use to the outdoor applications. Therefore, a remarkable attention was the first in the literature, is proposed in this thesis by introducing single negative metamaterials to the folded antipodal Vivaldi antenna structure. This work is developed based on a systematic approach which can be divided mainly into four parts : First of all, design a single negative metamaterial structure of a surface area 5×5 mm2 on an FR4 - Epoxy substrate. The unit cell properties are evaluated numerically and analytically, then, compared to the measurement. Second, a systematic approach is applied to design an antipodal Vivaldi antenna based flat profile of a corrugated shape with 50×38 mm2 on the FR4 - Epoxy substrate. Third, the best arrive of the flat geometry is folded on a hello Teflon substrate of an elliptical cross - sectional area. Fourth, the folded antenna structure is surrounded by a U - shaped single negative metamaterial array. The performance of the all proposed antennas are evaluated numerically, then, compared to their measurements in both S11 and radiation patterns. It is found that the antenna bandwidth has affected insignificantly by applying the metamaterial structures. However, with respect to the flat antenna model, the gain is increased generally by 6 dB as well as the radiation pattern is oriented to the broadside. It is worth to mention that the achieved enhancement in the gain is mostly attributed to the folded substrate and the metamaterial introduction. While, the bandwidth enhancement is mostly obtained from the folded antenna structure. The optimum structure shows a first mode around 1.4 GHz and the second one at 2.86 GHz, while, the flat antenna only one mode at 1.5 GHz is appeared.Finally, the HFSS, CST MWS, Matlab and ADS software packages are used in this thesis to study the unit cell performance and the antenna structure. Excellent agreements have been found between the simulated and measured results.

المستخلص: This in vitro study was conducted to evaluate and compare the efficiency of XP - endo Finisher, EndoActivator sonic irrigation system and the NSK Varios ultrasonic irrigation system in removing dentin debris at three levels of root canals and to compare the percentage of dentin debris among the three levels for each irrigation system. Sixty freshly extracted upper molar teeth with straight palatal root canals were used in this study. All canals were prepared with ProTaper NEXT rotary files to size X4, 1mm from the anatomic apex with irrigation of 1 ml 2.0% NaOCl between the files. After that the samples were randomly distributed into three groups of twenty samples each, irrigated with 1 ml 2.0% NaOCl, followed by irrigant activation for 60 seconds with three different irrigation systems; group one, by using the XP - endo Finisher; group two, by sonic irrigation using the EndoActivator system; and group three, by ultrasonic irrigation using the NSK Varios, then all the groups received a final rinse of 5 ml 2.0% NaOCl. After the final rinse, the roots were split longitudinally into two parts and photographed with a professional digital camera. The digital images were then transferred into a computer and opened in Adobe Photoshop CC 2015 software and the canal was magnified 200x. The percentage of dentin debris remaining at the apical level (0 - 3mm), the middle level (3 - 6mm) and the coronal level (6 - 9mm) was calculated by dividing the number of pixels occupied by the dentin debris at each level by the number of pixels representing the entire canal area. Data were analyzed statistically by ANOVA and LSD at 1% and 5% significant levels. This study showed that cleaning the canal with the XP - endo Finisher or NSK Varios ultrasonic irrigation system resulted in significantly cleaner canals (P<0.01) than the EndoActivator sonic activation system at all canal levels. The XP - endo Finisher resulted in cleaner canals than the NSK Varios ultrasonic irrigation system at all levels, but the difference is not statistically significant (P>0.05). The apical level of all the canals showed a greater amount of dentin debris (P<0.01) compared to the middle and coronal levels, regardless of the irrigation device used.

المستخلص: t is important to analyze and compare the stresses induced in different composite material types during load application to know which type of composite will behave as preferred under the loading in the same circumstances. This study aimed at measuring and comparing the stress induced in Filtek ™ Z350 XT (3M ESPE) composite, Tetric EvoCeram ® (ivoclar vivadent) composite and BRILLIANT ™ NG (Coltène/Whaledent) composite experimentally and numerically.Experimental analysis included cavity preparation in the Brass block with a concave (U - shape) cavity which represent a proximal cavity preparation. This cavity was used as a mold for sample preparation. The internal line and point angles of the cavity (mold) were rounded and the dimensions of the cavity (mold) were 10mm × 10mm × 10mm (Total height of the box × Width of the top side of box × Length of the top side of box). The internal diameter of “U” was 5 mm at the base of the box. The mold was used to prepare forty five samples, fifteen samples for each type of composite material. So, three groups were prepared : Group A filled with Filtek ™ Z350 XT composite material, Group B filled with Tetric EvoCeram ® composite material and Group C filled with BRILLIANT ™ NG composite material.Electrical strain gauge (Tokyo Sokki, Japan) was embedded in composite material horizontally at the same level in each sample. Static load of 50 N was applied perpendicular to the center of the occlusal surface of composite restoration in each sample testing. The strain gauge was connected to a Wheatstone bridge with a signal amplifier which measures the strain during load application and gives the amplified signal from (0 to 4.8 volt) to LabJack data acquisition where a stream software give the final values of strain with the aid of a scaled equation of voltage. Then, the von Mises stress (effective stress) was calculated by using equations. Numerical analysis was done by using ANSYS 16.1 - (2015) (finite element tool) software that was used to create the 3 - Dimensional models represented the same materials and dimensions used experimentally. The physical characteristics of the composite models were inserted in the software which included Elastic modulus and Poisson’s ratio (?). Analysis was selected in a finite element method according to boundary conditions. A mesh size and an element size were estimated during the study. The stresses were calculated at static load of 50 N with the ANSYS 16.1 - (2015) software.The data were analyzed statistically by One - way ANOVA test and Least Significant Difference (LSD) test. One - way ANOVA test and LSD test results showed that there was a highly significant difference (P<0.001) presented between groups A and B, groups A and C and between groups B and group C. The Stress induced in BRILLIANT ™ NG composite after load application was the lowest stress value followed by Tetric EvoCeram ® composite and followed by Filtek ™ Z350 XT composite which was the highest stress value experimentally and numerically.

المستخلص: Although investigators have evaluated the microleakage of porcelain laminate veneers, there is insufficient data regarding the durability of porcelain laminate veneers bonded to existing composite fillings. The aim of this study was to evaluate the microleakage of porcelain veneers restorations fabricated from two types of CAD/CAM ceramic blocks bonded to teeth with or without composite class V composite filling.Forty eight sound, crack - free human maxillary first premolar extracted for orthodontic reasons were selected for this study. Teeth were divided randomly into.2 main groups, which further divded into 2 groups (12 sample each). Group A1 : IPS e.max CAD veneers with standardized class V composite filling, Group A2 : IPS e.max CAD veneers, Group B1 : VITA Suprinity veneers with standardized class V composite filling, Group B2 VITA Suprinity veneers. The class V cavities was restored with nanofilled composite (Filtek™ Z350 XT, 3M ESPE). Standard veneer preparations were made using Ceramic veneer burs system (Keramikveneers. de, Komet). All the veneers were milled by CAD/CAM technology (CEREC MC XL, inLab SW 15, Sirona Dental Systems) Composite fillings (groups A1 and B1) were sandblasted with alumina oxide.Porcelain veneers were cemented in place using light - cured resin cement (Rely Veneer Cement, 3M ESPE), Then the specimens were stored at 37? in distilled water for 2 weeks. Then mechanical load cycling (50,000 load cycle of 49 N at 2.5 Hz) and thermocycling procedure (500 cycles of 5 - 55 Co with 20 sec dwell time) were done. The specimens’ crowns were immersed in 2% methylene blue dye for two days, then mounted in clear acrylic before sectioning with a 0.35 mm microtome. Microleakage percentage were recorded using stereomicroscope and ImageJ program. Results were checked for normality of distribution (Kolmogorov - Smirnov test and Shapiro - Wilk test), and were analyzed with twoway ANOVA and independent samples t - tests. Two way ANOVA shows the significant effect of type of ceramic restoration and the highly significant effect of composite filling, however, the interaction between the main factors was non - significant. The results showed that the lowest mean of microleakage percentage was recorded for group A2 (4.6058% ± 1.5091) which considered statistically significant compared to group B2 (6.105%±1.456), and statistically highly significant compared to group A1 (6.6075%±1.3259) while group B1 recorded the highest mean of microleakage percentage (7.3158%±1.38713). In conclusion, the type of ceramic restoration and the presence of class V filling both had significant effects on microleakage of porcelain veneers. IPS e.max CAD veneers had significantly lower microleakage percentages compared to VITA Suprinity veneers. The presence of class V composite filling within the cervical finishing line of porcelain veneers had a highly significant higher microleakage percentage compared to groups without composite filling.

المستخلص: Acute coronary syndrome (ACS) refers to any group of acute signs and symptoms attributed to sever obstruction of the coronary arteries. Acute coronary syndrome usually occurs because of one of three problems : ST elevation myocardial infarction, non - ST elevation myocardial infarction, and unstable angina. These types are named according to the results of the electrocardiogram (ECG). In addition to clinical and electrocardiogram (ECG) findings, several biochemical markers are considered in patients with chest pain to diagnose myocardial ischemia. Heart failure (HF) according to American College of Cardiology (ACC) and American Heart Association (AHA) is a complex clinical syndrome that can be caused by any structural or functional disorder in the heart that fails the capability of the ventricle to fill with or to eject blood. The diagnosis is often performed clinically on the basis of the presence of dyspnea, fatigue, signs of fluid overload, such as pulmonary crepitation, peripheral edema, and distension of jugular vein.B - type natriuretic peptide (BNP) and N - terminal pro - BNP (NT - proBNP) are secreted by human atrial and ventricular myocardium. The rise in BNP and NT - proBNP levels after ACS and HF correlates with infarct size and regional wall motion abnormalities. Echocardiography remains the most frequently used and usually the initial imaging test to evaluate all cardiovascular diseases related to a structural, functional, or hemodynamic abnormality of the heart or great vessels. This study is designed to investigate and assess the serum concentrations of BNP and NT - proBNP in patients with HF and ACS; In addition, almost equal number of males and females are chosen to control the effect of age and gender on the levels of BNP and NT - proBNP. Also, the study aims to evaluate the effect of BNP gene T - 381C (rs198389) polymorphism on the plasma human levels of BNP and NT - proBNP and compare the results that will obtain with healthy control.The present study was involved (70) patients, (35) of them with ACS and the other (35) with HF. The study also includes (22) subjects were taken as control group. The sera obtained from the blood of patients and control subjects were used to measure the concentrations of BNP and NT - proBNP, while whole blood samples from study subjects are used to extract DNA for the study of polymorphism in BNP gene.The results indicate both the ACS and HF groups have significantly higher levels of BNP and NT - proBNP when compared to control group, also HF patients have higher levels of both parameters than ACS patients, in all comparison (p

These women and their infants contribute significantly to obstetric &neonatal health care costs. The prediction of delivery latency could help direct the need for specific interventions such as hospitalization, intensive monitoring, timing of antenatal steroids.Objective : To determine whether transvaginal CL, AFI,or a combination of both can predict delivery latency within 7 days in women presenting with PPROM.Methods and Study Design : This was a prospective observational study of TVCL measurements in 80 singleton pregnancies with PPROM between 24 - 34 weeks. Transvaginal ultrasonography was performed with TOSHIBA SSA - 340A(Tokyo - Japan) apparatus 7.5MHz transvaginal probe, to measure the CL&AFI. Delivery latency was defined as the period from the initial TVCL after PPROM to delivery of the baby with our primary outcome being delivery within 7 days of TVCL. The independent predictability of significant characteristics for delivery within 7 days was determined using multiple logistic regression.Sensitivity, specificity, and predictive values were used to determin, whether the presence of a short TVCL, AFI or a combination of both affected the risk of delivery within 7 days.Result : Our study in women with PPROM show the validity of CL in predicting labor when the cut off value2cm the sensitivity=52.6%, specificity=69%, PPV=60.6%, NPV =61.7% and Accuracy=61.25%.The validity of AFI when the cut off value 5cm the sensitivity=71.1%, specificity=50%, PPV=56.3%, NPV=65.6% and Accuracy=60%.With combination of CL&AFI in predicting time of labor after PPROM the sensitivity=50%, specificity=92.8%, PPV=86.4%, NPV=67.2% and Accuracy 72.5%.In women with PPROM the rate of gestational age ? 30 weeks that labored within 7 days 44.7% and those labored more than 7 days 55.3%.Also the rate of gestational age >30 weeks that delivered within and after 7 days are 50%.According to the parity we found the mean value of those delivered within 7 days are 1.24 and those after 7 days are 1.28.Conclusion : Our study shows there is increase in positive predictive value when combination of AFI and CL in prediction of time of labour so women with AFI?5 and CL?2 had 86.4% risk of delivery within 7 days after PPROM. Also the study found there was no significant association between gestational age, or parity with the prediction time of labor.

المستخلص: Numerous interventional cardiovascular disease outcome studies have resulted in statins being an essential factor of cardiovascular primary and secondary prevention strategies.In recent years there was ahigh concern that statin use is associated with diabetes new onset which is strong, independent risk factor for cardiovascular (CV) and cerebrovascular outcomes ,several studies resulted in conflicting results regarding different statin types & dose effect on glycemic control. Atorvastatin which is the most widely used statin worldwide and rosuvastatin the most efficacious ;they have different structural characteristics that have been speculated to have influence on diabetes onset.Aim of the study : The present study aims at investigating the effect of different doses of atorvastatin and rosuvastatin on glycaemic indices and metabolic disorders on mice model of diet induced obesity. Materials and method : The animals were divided into two groups : one served as control that received normal regular chow & the other group received high fat diet for the whole 12 weeks of experiment.After eight weeks of HFD feeding ;group (2) farther subdivided into five groups(12 mice in each) ; the first group received HFD only ,the second group received single daily dose / po of 20mg /kg rosuvastatin ,the third group received single daily dose / po of 40mg /kg rosuvastatin ,the fourth group received single daily dose / po of 20mg /kg atorvastatin ,and the fifth group received single daily dose / po of 40mg /kg atorvastatin for the last four weeks of experiment.Body weight ,food intake, lipid profile ,glycaemic indices were taken at baseline ,before treatment and after treatment.At the end of experiment ,animals were sacrificed , plasma & tissue sample were collected for biochemical analysis and histological observations.Results : Results of the present study shows that high fat diet feeding resulted in obesity development and metabolic abnormality like; hyperglycemia ,hyperinsulinemia ,insulin resistance , dyslipidemia and moderate to severe hepatic steatohepetitis compared to control group. and treatment resulted in significant improvement in lipid profile ,reduction in food intake ,body weight ,also associated with improvement in insulin sensitivity , hepatic steatohepetitis and reduction in insulin secretion.twenty mg/kg dose of atorvastatin showed better influence on glycaemic indices and comparable influence on hepatic picture over fourty mg/kg does while twenty mg/kg dose of rosuvastatin resulted in deterioration of glycaemic indices and no apparent improvement in hepatic steatosis. Unlike group that received 40 mg /kg rosuvastatin which showed significant improvement in all related metabolic disorders. Conclusion : Feeding mice with high calories diet for 2 month result in induction of obesity and disturbance of metabolic parameters. Treatment with rosuvastatin or atorvastatin has good impact on bodyweight , metabolic derangements &hepatic steatosis in obese mice. Both drugs seems to improve lipid profile in dose dependent manner, however their effects on glycaemic indices has different attitude. It is seems that rosuvastatin, especially at high dose, has better impact on glycaemic indices than atorvastatin and this might attributed to the difference in their pharmacokinetic properties

المستخلص: الخلفية : داء السكري يشير الى مجموعة من امراض الايض مع ارتفاع مستوى سكر الدم. يمثل النوع الثاني من داء السكري ما نسبته 90 - 95% من جميع حالات السكري. يمثل النقص في الانسولين ومقاومة الانسولين وغيرها من الاضطرابات الهرمونية المشاكل الاساسية لمرضى السكري من ال | Background : Diabetes mellitus (DM) describes chronic metabolic disorders with hyperglycemia. Type II DM (T2DM) represents for approximately 90 - 95% of all diabetic types. A combination of insulin deficiency, insulin resistance and other hormonal irregularities are key problems with T2DM. Adipose tissue can be classified into two types : the brown and white adipose tissues. The white type is considered an important secretory organ which produces many bioactive molecules, collectively termed adipokines. Recently, a new adipokine named omentin - 1, has been identified and it was found that individuals with impairment in glucose homeostasis and newly diagnosed T2DM showed a lower serum omentin - 1 level. However, the effects of antidiabetes drugs on serum omentin - 1 level had not been studied extensively.Objective : The current study was design to measure serum omentin - 1 in T2DM as comparing with control subjects, also to study the effect of three months therapy with metformin and/or sitagliptin (when added to ongoing metformin therapy) on serum omentin - 1 levels in addition to other parameters.Method : This study was carried out on thirty healthy control subjects, and sixty three T2DM patients. The patients enrolled in the current study were divided into two groups. First group : included thirty one of newly diagnosed T2DM patients, started treatment with metformin. Second group : included thirty two patients with T2DM, already on ongoing metformin therapy and started treatment with sitagliptin. All patients received their treatment for three months duration, and blood samples were collected from them at the beginning of the study and after three months of starting treatment to measure the possible change in the studied parameters which include : fasting blood glucose (FBG), postprandial blood glucose (PBG), Glycosylated haemoglobin (HbA1c), serum level of insulin, insulin resistance (IR), serum omentin - 1 levels, lipid profile, body mass index (BMI) as well as blood pressure. Results : The results showed that baseline level of serum omentin - 1 in the newly diagnosed T2DM was significantly lower than matched control subjects. The level of omentin - 1 was significantly reduced after three months duration of treatment in sitagliptin group with no significant change in metformin group. FBG, HbA1c and PBG were decreased significantly after three months in metformin group, while in sitagliptin group, only HbA1c and PBG were decreased significantly after three months. In both groups, and after three months duration of treatment, there were no significant changes in serum level of insulin, IR, TG, VLDL - C, HDL - C, BMI, and blood pressure.Conclusion : In newly diagnosed patients with T2DM, serum omentin - 1 was reduced compared to age and BMI matched healthy subjects. Three months treatment with sitagliptin resulted in a significant reduction in omentin - 1 levels compared with baseline values. However, three months treatment with metformin had no significant effect on serum omentin - 1 level compared with pre - treatment value

It is well known that pediatrics age groups are at higher risk for sedation - related complications than adults. Auditory brainstem response testing is one of the important diagnostic procedure that usually need sedation in order to preformed in children. Chloral hydrate is a hypnotic agent used since 1832 with low incidence of adverse events; whoever, despite the world wide use it is being abandoned due to bitter test, long time of sedation onset, vomiting and mild sedation. Rectally diazepam, on the other hand, produces higher and fast concentration in CSF with greater rate of success but probably with higher adverse events. Aim of the study : were to compare the sedative effect of chloral hydrate with chloral hydrate diazepam combination as well as their related adverse effects in children underwentg auditory brainstem response testing. Methods : in this randomized clinical study, 160 child underwent sedation for auditory brainstem response test participated. They were divided equally and randomly into 4 groups. Group A : Received 20 mg/Kg oral chloral hydrate as sedative, Group B : Received 20 mg/Kg oral chloral hydrate plus 0.5 mg/Kg diazepam rectally, Group C : Received 40 mg/Kg oral chloral hydrate as sedative, and Group D : Received 40 mg/Kg oral chloral hydrate plus 0.5 mg/Kg diazepam rectally. At the beginning, blood pressure, respiratory rates, peripheral oxygen saturation recorded, and then re - recorded immediately after drug administration and at (3, 5, 10, 20, …. min). Ramsay sedation scale used for assessment of the sedation level which measured every 10 min. Results : This study shown the beneficial use of chloral hydrate in combination with diazepam as sedation in ABR test (in groups D) by increased in the sedated number (p<0.05), decreased in the requirement of chloral hydrate re - dose, increased in the number of children whom completed ABR test (p<0.05) without significant differences on side effects or vital signs compared with the others three groups. 4.3. Conclusion : From this study we concluded that : • Used of oral chloral hydrate in dose (20mg/kg) alone not sufficient as sedative in paediatrics for ABR test.• Used of oral chloral hydrate dose (20mg/kg) in combination with rectal diazepam (0.5 mg/kg) better than used it alone as sedative in paediatrics for ABR test.• Used of oral chloral hydrate dose (40mg/kg) in combination with rectal diazepam (0.5 mg/kg) was the best sedative in paediatrics for ABR test. • Used of Chloral hydrate diazepam combination in ABR test of paediatrics increased the number of the sedated children, decreased the requirement of chloral hydrate re - dose, and increased the number of completed ABR test, with less complication

Therefore this study includes the evaluation of the immune status in sera of Babylon governorate displaced and residents with specific aspect for isolation and identification of measles virus from suspected cases. The immune response was evaluated by means of ELISA test (enzyme linked immunosorbet assay) for titration of IgM and IgG immunoglobulin level, in addition to evaluation of perforin level in the sera of 90 measles vaccinated individuals included in this study (50 displaced and 40 residents) from different areas in Babylon governorate, that were collected during the period extent from January up to April of 2016. Data about individuals were fixed according to information of formula including age, sex, geographical location, place displace of displaced and the vaccination date. Successful virus isolation from suspected cases on two types of cells culture included Vero cells line and chicken embryo fibroblast was carried. The titer of the isolated virus on Vero cell line reached (105.8 TCID50 / 0.1ml),which was higher than the titer of the virus isolated on CEF which reach (105.4 TCID50 / 0.1ml) after the third passage of the virus. The isolated virus was confirmed by indirect immunofluorescence technique.The age of subjects included in this study ranged from <1 year up to 24 years old. The results revealed that 15 (30%) have positive IgM index in sera of displaced, whereas residents sera sample shown only 6 (15%) positivity. Howover, all 90 (100%) subjects of both groups showed positive IgG index. The results of the present study showed that there were no significant difference of perforin level in sera of refugees and residents at p<0.05.Assaying of immune response against measles virus by measuring IgM immunoglobulin in sera of vaccinated displaced and resident with measles vaccine reflected a highly significant difference between two groups which reached 0.43 mIU/ml in sera of displaced in comparison with residents sera which reached 0.34 mIU/ml. The result showed also high significant differences in IgM between females and males. The females sera IgM levels of displaced and residents were higher than its level in males sera which reached 0.47 mIU/ml and 0.35 mIU/ml, respectively, in comparison with male sera level which reached 0.40 mIU/ml and 0.32 mIU/ml, respectively. According to age group, the highest IgM value was recorded in displaced and residents sera in age group 10 - 14years (0.50 mIU/ml) and 5 - 9years (0.36 mIU/ml) respec - tively. Whereas the lowest IgM serum value was detected in age group <1 year (0.34 mIU/ml) and 15 - 19years (0.31 mIU/ml) for displaced and residents subjects. According to geographical location, the highest IgM level was detected in sera of displaced from Tal Afar city (0.44 mIU/ml) followed by displaced from Ramadi (0.41 mIU/ml) and the lowest IgM value was detected in sera of displaced from Mosul city (0.33 mIU/ml). Whereas the highest IgM value in sera of residents in the subjects of Al - Mahaweel city (0.37 mIU/ml) followed by subjects of Hilla and Al - Qasem city (0.29 mIU/ml and 0.28 mIU/ml) respectively. For IgG serum immunoglobulin the results revealed that there was no difference in significant levels in both group population. But according to age groups significant difference between displaced and residents was detected at p <0.05 in which the 1 - 4 years old showed the highest IgG serum level in both group (1.98 mIU/ml and 2.18 mIU/ml) respectively. While the lowest IgG sera value was recorded in displaced age group of < 1 year old (0.60 mIU/ml) compared with residents age group of 20 - 24 years old (1.65 mIU/ml).It could be concluded that the results showed that the displaced do not have any effect on the residents of the province of Babylon for measles as a result of the good immunization by Babil Health directorate following to the Ministry of Health.

So considering the impact of anti - diabetic drug on omentin - 1 levels may provide adjuvant strategy to protect diabetic patients against clinical hazards.Aim of the study : The present study aimed to investigate the influence of treatment with metformin alone or in combination with gliclazide on the level of serum omentin - 1, in addition to the other biomarkers adopted in the study in order to evaluate whether the combined therapy (metformin plus gliclazide) ameliorate or adversely effects on some cardiac protector markers of metformin among recently diagnosed patients with type 2 diabetes mellitus.Methods : A total number of 100 recently diagnosed patients with type 2 diabetes mellitus were enrolled in the present study from December 2014 until June 2015. Sixty eight patients completed the 12 weeks course of treatment; divided into two equal groups based on treatment regimen in which group1 treated with metformin and group2 treated with metformin plus gliclazide. Thirty two patients did not complete the course of the treatment for unknown reasons and considered as default. In addition to 31 healthy volunteers were randomly chosen and considered as Control Group. In which all the participants in the study underwent detection of blood pressure, pulse rate, weight, height & BMI in addition to the estimation of the levels of others biochemical analysis as glycemic indices, lipid profile & serum omentin - 1at the beginning of the study & after 12 weeks of treatment regimen.Results : The results of this study shown the beneficial amelioration of metformin on some markers that affect CVS represented as significant reduction in BMI (p<0.05), modest improvement in lipid profile with modest elevation in HDL level & lowering blood pressure, significant reduction in the levels of blood glucose & HbA1C (p<0.05), improves insulin sensitivity, reduced insulin resistance, and elevation of serum omentin - 1 level among newly diagnosed type 2 diabetic patients (group1). Furthermore, the results of current study are revealed that adding of gliclazide to metformin in treatment of type 2 diabetic patients might influence the documented beneficial effects of metformin on cardiovascular system at least by adversely changing the levels of serum omentin - 1 among group 2. Conclusions : Adding of gliclazide to metformin in treatment of patients with type 2 DM might extend the therapeutic action of metformin in regarding much better controlling of glycemic indices, insulin sensitivity and lipid profile. But, at the same time, it might attenuate some of beneficial effects of metformin on cardiovascular system at least by adversely influence on body weight and serum omentin - 1 levels.

It is well known mitochondrial uncoupler.Aim of the study : The present study aimed to investigate the influence of trial of the use of niclosamide in comparison to effect of metformin and their combination on body weight , glycemic indices and lipid profile in high fat diet induced obese mice.Materials and methods : The animals firstly divided to two groups one fed with normal regular mouse chow (30 mice) and the 2nd fed with high fat diet (60%kcal) for 2.5 months(100 mice) 10 mice from each group sacrificed at beginning of study represent baseline values and another 10 mice from each group sacrificed after 2.5 months to assess effect of high fat diet on study parameters. The group that fed with high fat diet further subdivided to 4 groups after 2.5 month of high fat diet feeding each 20 mice , 10 mice from each group sacrificed before treatment represent pretreatment values. Before treatment there are 5 groups assigned as group 1 fed normal regular mouse chow till the end of study , group 2 fed high fat diet without treatment till the end of study , group 3 fed with high fat diet till the end of study and treated with niclosamide for one month (150mg/kg) after obesity induction by high fat diet , group 4 fed with high fat diet till the end and treated by metformin (300mg/kg) for one month and finally group 5 fed with high fat diet till the end of study and treated by combination of niclosamide and metformin (150mg/kg , 300mg/kg respectively). blood samples taken from tail vein to evaluate the study parameters at baseline and after obesity induction by high fat diet (after 2.5 months) and after treatment ,then animals were sacrificed and livers were taken for histopathological observations.Results : The results of this study shown that the animals fed with high fat diet show metabolic disturbances manifested by significant increase (P < 0.05) in body weight , fasting insulin & fasting plasma glucose. Lipid profile show significant changes (P < 0.05)(cholesterol , triglycerides ,low density lipoproteins increased while high density lipoproteins decreased ) as compared to control group. High fat diet group also show impaired glucose tolerance , impaired insulin sensitivity and obvious liver structural changes manifested by sever steatosis.Treatment with niclosamide show improvement in all metabolic disturbances induced by obesity ; body Weight , fasting insulin and fasting plasma glucose reduced significantly (P < 0.05). Lipid profile parameters improved ; cholesterol , triglycerides , low density lipoproteins reduced significantly (P < 0.05) by one month treatment with niclosamide and high density lipoproteins increased significantly (P < 0.05) as compared to their baseline values before treatment, Glucose and insulin tolerance improved. It is nice to mention the influence of niclosamide in this study was comparable to metformin in all evaluated parameters.Combination of both drugs show favorable improvement in metabolic disturbances induced by obesity rather than each drug when used alone specially on liver histopathological changes.Combination of both drugs show significant reduction (P < 0.05) in body weight ,fasting plasma glucose and fasting plasma insulin. Lipid profile parameters improved significantly (P < 0.05) , glucose and insulin tolerance improved.Liver histopathological changes ameliorated to higher extent and become the closet to normal liver tissue morphology.Conclusions : The result suggest niclosamide have good antidiabetic action and can ameliorate the metabolic changes induced by obesity significantly. Its action is comparable to that of well known antidiabetic drug metformin. Niclosamide has favorable effect on body weight and can reduce body weight. Its combination with metformin show better improvement in metabolic disturbances induced by obesity and it has very good hepatoprotective effect against liver histopathological changes induced by high fat diet.

المستخلص: اساس الدراسة : اجريت الدراسة الحالية لتقييم التاثير العلاجي لعقار السيتاكولين والجنسنك واستخدامهما معا على الذاكرة القصيرة المدى والاداء الحسي الحركي, وذلك من خلال دراسة الاثار المركزية والطرفية للعقارين على مقاييس الاداء الحسي الحركي , الذاكرة العمليه , | Citicoline is one of components that present in the human brain, which act to protect the neurons and enhance memory and other cognitive functions due to its choline in their structure which play an important role in the biological membrane biosynthesis. On other hand Ginseng is an herbal plant is known for its therapeutic medical importance, it's used for different purposes in medical fields, that is effective against many diseases, act as a tonic and provide energy with significant reduction in mental and physical fatigue.Aims of the study To evaluate the central effects of Panax Ginseng and/or citicoline on normal healthy volunteers.Material and Method The subjects are randomly divided into four groups for assessment of central effects of Panax Ginseng and /or citicoline compared with placebo. The evaluation of the central effects was done by using the Leeds psychomotor battery tester for evaluating the psychomotor performance, workshop test was used to evaluate working memory function.The enrolled volunteers were randomly divided into the following groups : First group regarded as control group that treated with 500 mg/day of starch capsule as a single dose, second group, received Panax Ginseng capsule 500 mg /day, a third group received citicoline capsule 500 mg/day and the fourth group received Panax Ginseng capsule 500 mg/day plus citicoline capsule 500 mg/day as a single dose. All participants are followed for two consecutive weeks from starting treatments.ResultsIn the present study the placebo didn't have any central effect and MDA serum levels were not significantly change. Panax Ginseng has statistically significant effect on the most parameters of the psychomotor performance, working memory performance, as well as reduction of MDA serum levels. On the other hand, citicoline has statistically a significant effects on most parameters of the psychomotor and working memory function with statistically significant reduction of MDA serum levels.The combination of Panax Ginseng and citicoline have a highly statistically significant effect on all psychomotor performance, working memory performance and statistically significant reduction in the oxidative stress marker (MDA). ConclusionResults of the present study showed that combined effects of citicoline plus Panax Ginseng on central function produced more statistically significant effects on psychomotor performances, CFFF and working memory function than either Panax Ginseng or citicoline when they used alone, in addition to the combined effects of citicoline plus Panax Ginseng have a more significant effect on the oxidative stress,during mental stress.

المستخلص: تتباين انظمة الرعاية لحديثي الولادة المطبقة ولكنها كلها تعتمد على وحدات الخدج الموجودة في مختلف بلدان العالم النامية والمتقدمة.انجزت هذه الدراسة المقطعية التقويمية في وحدات حديثي الولادة لردهات الولادة في مستشفيات بغداد (الكرخ والرصافة) مستثنين وحدات ال | Neonatal health care is provided via a variety of neonatal care units that are available globally both in different developing and developed countries.A cross - sectional evaluation study was conducted in all accessible fifteen neonatal intensive care units in Baghdad (Kharkh and Rosafa) maternity wards, excluding paediatric hospitals, during the period from November 2013 till the end of March 2014.The study aims : 1. Health care evaluation in neonatal intensive care units of maternity wards in Baghdad hospitals in terms of input (human and non - human resources) and outcome.2. Identifying causes of admissions and causes of deaths occurring in neonatal intensive care units The study consisted of two parts : A structure evaluation is using a check list to assess availability of human and non - human resources, covering infrastructure, manpower, equipment, and supplies; and an outcome evaluation study using hospital registration records review for causes of admission and causes of death in neonatal intensive care units during the year 2013.It was found that the mean number of specialist doctors in neonatal intensive care units was 2.1 and with standard deviation ±1.3, and college nurse was 2.2, with standard deviation of ±4.004, pharmacist was 0.4 with standard deviation of± 0.516 and for supplementary staff 1.5 with standard deviation of± 0.516.More than half 54% of nurses had no training in neonatal care.Concerning the availability of general equipment it was adequate except for computers 40%.Air conditioning, lighting and windows in addition to safe water supply was good 100% but ventilation was poor 67%, hand washing area was not always present 60% and free elbow operated water tubes were available in 6.7%. Availability of neonatal intensive care units special area was adequate for storage area 85.7% gowning area78.6%, while all the remaining areas were poorly available (resting room, examining room, mother room, boiling and autoclave room, area for mixing intravenous fluid and medication).Neonatal intensive care units were narrow and area/incubator ranging from 2.28m2 to 4.36m2/ incubator. Number of incubators was 246 with patient/ incubator ratio 53.6 : 1 and 27% of Neonatal intensive care units had no regular maintenance for incubators. Large Neonatal intensive care units >25 incubators were overcrowded, having below standards area/incubator, incubators covers only two third of neonatal care. Still up to one third of Neonatal intensive care units are getting their oxygen supply by cylinders, not pipes. Most equipment for individual use were poorly available. Most of Neonatal intensive care units emergency (cupboard) drugs and supplies were sufficiently available round the clock. Total admissions to Neonatal intensive care units were 13195 neonates. Male neonate's admissions 60% were higher than females 40%. Main causes of admission were Respiratory distress syndrome 43%, prematurity and low birth weight 19.4%, and Transient tachypnea 17.4%; birth asphyxia 4%, and hypoglycemia 3.8%, Congenital anomalies 3.7%, Neonatal jaundice 3%, while meconium aspiration and septicemia were the lowest1%. From all these admissions 74% were discharged well, (6%) were referred, while those discharged against medical advice were (4%) and the rest (16%) died. The main causes of death in Neonatal intensive care units were Respiratory distress syndrome 34%, prematurity and low birth weight 31% congenital anomalies 12%, birth asphyxia 8%, septicemia 4%, meconium aspiration 1% and 10% due to other unclassified causes. From this evaluation study, it can be concluded that there were Neonatal intensive care units with under staffing, undertraining and poor designing. Respiratory distress syndrome and prematurity were the main neonatal health problems.
