المستخلص: After intellectual evolution of the development in terms of its concept, Process and measurement indicators which is consistent with the current progress of human beings and countries. This evolution, however, is combined to shifts and international changes such as debt issue and financial crises, and then adopting reformation policies, and circumstances of globalization and its effect on the developing countries in particular. All these circumstances requested increasing and securing the requirements of welfare. In contrast, the emerge of current concept of human right within the global declaration framework of human rights in 1948, and its progress to deal with defending of human rights and its achievement. It embodied via increased number of declarations, covenants and conventions, and protocols issued and to be issued by the United Nations for securing a better life for humanity and its welfare, security and peace without any kind of segregation. Therefore, the consistent between development, as a social - economic process, and human rights as a privilege which people seek to obtain will be surest guarantee for the provision of various rights, especially economic, social and environmental rights. As well as development would not be achieved without respecting and protecting the human rights. Besides, the process of joining the development along with human rights system has a significant importance in change the style of beneficiaries from development as receivers of aids and outputs to human right owners. This means, the disruption and shortening of achieving the development indicators and its criteria would be subjected to accountability and evaluating by non - governmental and international organizations. Moreover, the availability of requirements of human needs represents enforceable commitments by the government and other linked institutions, where these needs became a right and privilege of individuals and communities and characterized in a legal dimension in achieving the developmental targets for obtaining the best indicators due to its linkage with human right agenda. However, the linkage between development and human right can lead to increasing level of dialogue and cooperation between individuals and society in one hand, and institutions that implement plans and developmental programs on the other hand. Hence, the priority is to consider all needs and work to achieve it without any ethnic, religious and geographical segregation. However, this reflects in the increase of level of justice of distribution of development output, which raise human well - being. As well as, this relationship will reduce the level of corruption and waste of development output as a result of expansion of concepts of rights and freedoms, which means increasing level of transparency and anti - corruption programs, also improving capacities that could achieve the welfare. In respect of Iraq, it is necessary to identify the level of convergence between the development and process of rights through presenting the achieved indicators limited by High Commissioner for Human Rights which is based on respecting human right representing by economic, social and environmental content. All these contents show a high need to improving its level in Iraq and mitigate the gap through the convergence between the planned developmental programs and the principles of human right. In order to achieve that, the study will measure a new indicator for development which it compatible with human rights based on a formulation used by the United Nations Development Program (UNDP), however, the study added new indicators derived from the development process and pillars of human rights.

المستخلص: مياه الصرف الصناعي لمصافي النفط الناتجة بصورة رئيسية من عمليات تكرير النفط الخام والصناعات التحويلية، مواد التشحيم والبتروكيماويات الوسيطة. هذه السوائل هي المصدر الرئيسي للتلوث البيئي المائي. تتكون مياه الصرف الصناعي من الزيوت والشحوم والمركبات العضوية ا | Petroleum refinery wastewater originating from petroleum industries primarily resulted in refining crude oil and manufacturing fuels, lubricants and petrochemical intermediates. These effluents are a major source of aquatic environmental pollution. The wastewaters are composed of oil and grease, toxic organic compounds along with many other minerals. In this study, wastewater of Al - Najaf petroleum refinery was used as electrolyte solution in the experiments, and the effect of some variables on the removal of organic material as a pollutant in term of COD were studied. The performance of anodic oxidation represented by COD removal was studied using 1 liter batch - mode parallel plate electrochemical reactor at constant initial COD concentration and fixed agitation speed of 250 rpm with the variation of operating conditions that were expected to have a major effect on process. These variables were : electrodes material (platinum, stainless steel, graphite, PbO2, and carbon felt), current densities (5, 15, 25) mA cm - 2 for carbon felt electrode and (10, 30, 50) mAcm - 2 for other electrodes, pH (4, 7, 10), temperatures (25, 40, and 55)?C and with electrolysis time up to 120 minutes. The results show that the direct anodic oxidation process gave the best COD removal percent of 84.88% and 86.27% at 50 and 25 mA cm - 2 current densities for PbO2 and carbon felt anode materials, respectively. The highest COD removal was predicted at pH 4 and the best temperature at 55?C for all electrode types. The reaction was followed by pseudo first - order kinetics rate. As well, it was studied the effect of current density on the current efficiency, instantaneous current efficiency, energy consumption, charge load with the time and calculated activation energy.

المستخلص: Silica nano particles were prepared from Iraqi rice husk (al - Najaf province) by precipitation method. Rice husk (RH) was treated with two different concentrations of inorganic acid (i.e. 1 & 3 N HCl) then burning at 700 °C under two heating rates. Chemical composition of rice husk ash (RHA) determined by X - Ray fluorescence (XRF) was contained about 89.5 wt% and 95.2 wt% SiO2 by treatment with 1N HCl at 10 and 5 °C/min heating rates for 3 hrs, respectively. While, XRF analysis was given 97.5 wt% SiO2content in RHA by treatment with 3 N HCl at 5 °C/min heating rates for 2 hrs. 3N HCl and heating rate at 5°C/min seems to be the best method to reduce the metallic ingredients and to obtain highly purified nanosilica powder at a purity of 98.9 wt%.The prepared nanosilica was also characterized by X - ray diffraction (XRD), BET surface, Fourier transform infrared spectroscopy (FTIR) and Atomic Force Microscope (AFM), in order to investigate its properties.X - ray results revealed a strong single beak of 2? at about 22° with an amorphous phase. Surface area was measured for nano silica to be 298 m2/g. The average diameter of prepared nanosilica is 89.58 nm as obtained by AFM analysis. Rice husk is seen to be a frugal waste material, high silica content, and it will be able to apply as a natural source of silica for preparation the zeolite - Y catalysts rather than burnt or dumped it as waste, causing environmental and health problems. On the other hand, the commercial source of silica (i.e. Ludox As - 40) is industrially used with other materials for synthesizing the zeolite type - Y catalyst and economically it has an expensive cost. Hence, it is essential to find out another pathway for silica source.This work deals with the replacing of costly commercial precursors of silica by a cheap natural nano - source silica from Iraqi RH. As such this study focuses on the optimization of percentages of natural and/or commercial silica applied within either seed gel or feed stock gel in the zeolite - Y synthesis process in order to investigate the effect of the nature of the silica used on both the structural properties of produced of Y - catalyst as well as on the catalytic performance of these catalysts in hydrocarbon cracking reactions forimproving the production catalytic activity and selectivity. Commercial zeolite - Y catalyst was laboratory prepared by means of commercial silica source and named as “A” sample, whereas other four samples of zeolite catalysts were successfully synthesized with a desired zeolite - Y phase and so - called “B, C, D and E” using different percentages of natural silica source. All the achieved samples are investigated by characterization techniques (i.e. XRD, BET - surface area, Pore volume, FTIR SEM, AAS, and EDX). The synthesized HY - catalyst samples were catalytically tested in the cracking of Hexane (C6H14) through an experimental cracking rig, and the reaction products were analyzed by GC. The performance of Iraqi RH zeolite type - Y catalysts was compared with the commercial lab HY - catalyst. Catalyst B prepares from only natural nanosilicasource and in comparison with other synthesized Y - catalysts; it gives the best catalytic behavior with 98 - 95 mol% conversion together with the selectivity domination of isomer and normal paraffin within the reaction products during more than 2 hrs at 450 °C. This result confirms that the use of natural silica source can be enhanced the catalytic properties of zeolite type - Y catalyst.

The first one was accomplished by the insertion of pilot symbols between the data stream that entering the encoder. In this way the pilot symbols are encoded along with the input data (encoded or internal pilots) in contrast to the usual way where pilots are inserted after encoding (unencoded or external pilots). The positions where pilots should be inserted are chosen in such a way that to improve the minimum Hamming distance and/or to reduce the error coefficients of the code. Moreover, the known pilots have higher reliability than data and can significantly improve the initial decoding.The second proposed algorithm includes the utilization of the inserted pilots to estimate scaling (correction) factors. Two - dimensional (2D) correction system was suggested in order to enhance the performance of traditional Minimum - Sum (MS) decoding of regular RA codes. By calculating the mean square difference (MSD) between the values of received pilots and the a - posteriori data of bit and check node related to them, which are created by the MS decoder, an adaptive method can be achieved for getting the correction factors.Since encoded pilots in systematic RA code are embedded in data, it is possible to puncture all or part of them to increase the code rate. The pilots still have their effect on increasing the minimum Hamming distance.Extensive simulation tests reveal that the suggested quasi - optimal algorithms supply error performance be able to compare as Sum - Product (SP) decoding whilst maintain less complexity. Practical experiments are carried out by utilizing the capability of data acquisition toolbox supported by MATLAB to provide a hardware interface with the computer sound card. Here, the sound card plays the role of ADC and DAC converter in the physical layer. A different graphical user interfaces (GUI) are designed for the transmitting and receiving terminals to facilitate the selection of different code options. Signals are transmitted over wireless channel using a 2.4 GHz band indoor audio tranceiver. According to the aquired results, the modified coding system outperforms the original one when it is tested over AWGN and fading channels. An improvement may be realized about 1.5 dB and 1.3 dB at BER=?10?^( - 5) for punctured and unpunctured systematic (50,35,3,7) code with adaptive scaling, with three encoded pilots over AWGN channel and about 3.4 dB and 3.3 dB at BER=?10?^( - 4) for punctured and unpunctured systematic (50,35,3,7) code with constant scaling, with two encoded pilots over fading channel.

المستخلص: Widespread wireless communications system in the last few years, leads people to ask many questions about the advantages and disadvantages of those systems, especially about electromagnetic waves pollution and their effect on human health.The mobile device is frequently used by the general public from adult to child, one of the main sources of electromagnetic waves and very close to the human head. Therefore the focus of this research on the impact of electromagnetic waves from mobile to human health by measuring the Specific Absorption Rate (SAR), at the human head and the hand through SEMCAD - X that uses the Finite Different Time Domain (FDTD). SAR computation uses (FDTD) in the way the limited space of time, to calculate the specific absorption rate. The results have been compared with standards averaged over any 1 g of tissue and averaged over any 10 g of tissue. It didn't exceed the applicable standard.This work evaluates specific absorption rate (SAR) at different ages of three people. Firstly, old man, who was estimated to head 100% size of header used in the program SEMCAD - X. Secondly Adult man was estimated his head by 85% size of header used in program, and finally the child who was estimated his head by 65% size of header used in the program SEMCAD - X, the design hand has been used with all cases.The design of the mobile phone software works in four different packages of frequencies; the packets are the center frequencies 900MHz 1800MHz, 2100MHz and 2400MHz, when increased frequency the SAR increased but in the some state and frequency decreasing.The Evaluation of SAR in the head and the hand of the user device and the generic phone, the highest value of SAR decreases with increasing distance between the generic phone and the user's head and reducing the proportion was 50% for the old man, 40% for adult man and 35% for child. It can be noted that the angle of the rotation of the various frequencies is not fixed, while the ratio approximately is 25% for each angle of rotation.Also, it can be noted that for fixed frequency, the input power is increased to a double and the SAR have been used increased almost to a double.The different positions show that the methods of holding generic phone have a significant impact on the value of SAR. Therefore, the value of SAR can be reduced into 90% when using the correct method.The evaluation of SAR in these cases shows their influence on children and it was much greater than the adult human or old human by parentage 40% old man and 35% adult man.

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.

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.

المستخلص: في ستينيات القرن الماضي كان هناك نوع من العلاجات تستخدم للسيطرة على وزن الجسم او لتخفيفه , تلك المواد تعمل على تثبيط عضيات المايتوكوندريا من انتاج الطاقة وتحويل مجرى تفاعلات الاكسدة نحو انتاج الحرارة بدلا عن الطاقة وبذلك تحفز من زيادة اكسدة الشحوم ومادة ا | Background : Obesity is a state of excessive accumulation of fat tissue in the body , increasing energy expenditure is good way to manage obesity and the related complications. Mitochondrial uncouplers increase energy expenditure , they used before for weight controlling programs because these compounds uncouple mitochondria from generating ATP , moreover stimulate lipid and glucose oxidation preventing lipid accumulation in excess caloric intake conditions specially. Niclosamide an old drug introduced in 1960s as anthelmintic and had FDA approval for the treatment of most of tapeworm infections. 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.

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.
