The current study aims to evaluate the association of (Interleukin 10, Tumor Necrosis Factor - α and Vascular Endothelial Growth Factor) genes polymorphism in psoriasis. Single Nucleotide Polymorphism (SNPs) determined by Polymerase Chain Reaction (PCR), restriction fragment length polymorphism (PCR - RFLP) and DNA sequencing techniques, while there serum levels determined by ELISA. This case - control study is done in a period of March 2015 to December 2017, where the samples collected from Marjan Medical City in Babylon Province. The number of samples was (64) patients psoriasis (40 males and 24 females ) with an average age ( 9 - 70 year), (50) of them were with type 1 psoriasis and (14) type 2. In addition, the study included 38 apparently healthy people who were (21 males and 17 females) with an average age (15 - 65 year), as control matched with disease group. The present study revealed a significant increasing (P<0.01) of Tumor Necrosis Factor - α (TNF - α) and Interleukin 10 (IL10) in patients compare with controls. In addition, there is a significantly regression between severity of disease and TNF - α serum level (r =0.49, p=0.0001) and non - significant invers regression with IL10 serum level (r= 0.29, P=0.0109). In addition, the results established an A significant negative correlation which has been found between IL10 and TNF - α (r= - 0.29) (p=0.0028). Physiological, the study shows significant increasing in Vascular Endothelial Growth Factor (VEGF) level in patient compare with control (P<0.01). There is no correlation between Vascular Endothelial Growth Factor (VEGF) serum level and severity or onest of disease (r= - 0.05).Genetically, analysis of the Single Nucleotide Polymorphisms PCR - RFLP genotyping for TNF - α - 308 G/A (rs1800629) SNP, Genotype distribution in patient were GG 35 (54.69%), AG 24 (37.50%) and AA 5 (7.81%) while in control were AG16 (42.11%), GG 12 (31.58%) and AA10 (26.31%).The genetic analysis of the Single Nucleotide Polymorphisms of VEGF +405 SNP, genotype distribution CC homozygous was predominant in patient 39(60.94%) and GG homozygous was 24 (37.05) While the GCwas the least 1 (1.56%). Comparing with the control group was CG 18(47.37%), CC 13(34.21%) and GG 7(18.42%).On the other hand , the statistical analysis for the role of genotyping for TNF - α - 308 SNP in the Serum levels of TNF - α were different between TNF - 308 AA (126.90 ± 14.96) patients and TNF - α GA(106.55 ± 16.42) and GG (57.94 ± 7.72) genotypes (p < 0.01). Analysis for the role of genotyping for VEGF +405 SNP non - significant difference between homozygous CC (408.30 ± 0.00), homozygous was GG (326.00 ± 34.81) and heterozygous CG (376.41 ± 58.63).This result promotes that the both of TNF - α - 308 SNP polymorphism and VEGF +405 SNP strongly implicated in the pathogenicity, severity and onest of psoriasis.PCR - sequencing for IL10 - 1082 A/G (rs1800896) locus shows a significant difference of percentage distributions of alleles and genotypes for IL10 - 1082 (rs1800896) locus between patient and control, GG homozygous was predominant in patient (71.5%) while the AG heterozygous was (28.5 %). Comparing with control group GG (100%).

Abstract: The present study aimed to search for safe and effective antifungal agents through investigation of the phytochemical characterization and bioactive properties of medicinal plants (Pimpinella anisum essential oil and Moringa oleifera and Malva sylvestris leaf extracts) and their effect on gene expression of keratinases produced by T. rubrum using Real Time PCR.Phytochemical analysis of active materials of P. anisum essential oil and M. oleifera leaf extracts were carried out, through TLC accompanied autobiography, high performance liquid chromatography (HPLC) and GC - MS analyses were proceeded to relate the chemical profile with their antifungal activity. Also, the cytotoxic effects of active compound and crude extract for both plant extracts were determined using MTT (3 - (4,5 - dimethylthiazol - 2 - yl) - 2,5 - diphenyltetrazolium bromide dye) assay. Screening the antifungal activity of Pimpinella anisum essential oil, Moringa oleifera leaf extracts and four traditional antifungal agents against growth and development of two strains of T. rubrum differed in their virulence were conducted. MIC for crud extracts and antifungal agent were also determined using microdilution plate, moreover, the effects of crud extracts and active compounds on gene expression was evaluated.Qualitative TLC, HPLC analysis for the anise essential oil extract revealed the presence of anethole which was identified as a main volatile compound in this extract which was identified as anethole. GC - MS analysis also revealed that trans - anethole is the major compound (96.8%), then Himachalene (1.84%), other components were also present but less than 1% e.g. Estragole, cyclohexene and 2 - Methoxy - 5 - (1 - propenyl) phenol. On the other hand, LC - MS analysis were showed the existence of that keratinase inhibitor (extracted from Moringa oleifera leaf)IICryptochlorogenicacid (C16H18O9), Astragalin (C21H20O11), so the presences of these compounds reflected the inhibitory effects on keratinase enzyme.The results upon screening, revealed that the anise oil inhibited both strains of T. rubrum, since the growth inhibition for first strain were 21, 30 and 39 mm at 15.6, 31.2 and 62.5 μl/ml respectively, while in second strain were 24, 32 and 39 mm at 15.6, 31.2 and 62.5 μl/ml respectively. The tested strains of this fungus revealed substantial sensitivity pattern toward crude extract of essential oil and anethole as well. Results showed that there was considerable growth inhibition for both strains of T. rubrum at minimal inhibitory concentrations (MIC) between 15.6 μg/mL for crude oil and 7.5 μg/mL for anethole. The inhibition in radial growth due to the effect of anise essential oil increased from 56% at 3rd day to 86% at the 7th day. Sporulation was substantially decreased by anise oil treatment. Anise oil was significantly inhibited conidial germination for both strains. Treatment with anise oil induced morphological changes in the conidial group where the conidia were absent in treated sample. Protease inhibitor isolated from mature leaves of M. oleifera showed great ability to inhibit keratinase activity of T. rubrum.MTT assay revealed that anethole is safe as phototherapeutic agents, when it is having no effects on normal cell, but shown anticancer activity against cancer cell.Anise oil, anethole, M. oleifera crud inhibitor, Cryptochlorogenic acid and Astragalin showed high inhibitory effects on gene expression of keratinase enzyme in both strains of T. rubrum KP979791 and KP979787.

Forty patients were examined during the period between July2015 to October 2015, and twenty seven patients were examined during period between June to August 2016, also the control group consisted of sixty seven healthy males ranged from 10 - 65 years.In this study asthmatic patients were divided into three groups according to medication , the first group consisted of (17) asthmatic patients taking antihistamines such as loratadine , citrizine and allermine , while the second group included (24) asthmatic patients taking montelukast , and the third group included (26) asthmatic patients who were on different drugs other than antihistamines and montelukast such as steroids and beta agonists .Five milliliters of blood were obtained from each patient, serum collected absolutely free from hemolysis stored at - 20 °C until uses for measurement of the concentrations of Glutathione, Malondialdehyde, Catalase, Histamine, Serotonin, Lipoxygenase - 5, Leukotriene A4 Hydrolase, total Immunoglobulin E and specific immunoglobulin E.The results revealed that the mean of IgE level (measured by ELISA system)in serum of asthmatic group was (368.16 ±1.772 ng/ml) versus the control group (138.9±2.515 ng/ml) with a significant difference,)P < 0.001(. Asthmatic patients and patients treated with pharmacological drugs such as montelukast and antihistamines showed high sensitivity to some food, animals, plant, palm pollen, fungal and mite allergen and they showed different values between patients and control. The study showed that there is no association between the increased sensitization to food, animal, plant and fungal allergens with age of patients.The present study showed the relationship of count blood cells (WBC and RBC) in studied groups. In all studied groups, WBC values higher than control group while the RBC values showed little differences among all studied groups.According to levels of some variables (histamine, serotonin, LOX - 5 and LTA4H) in asthmatic patients, the results showed a higher mean value of serotonin in asthmatic patients (0.023± 0.004 ng /ml) compared with control group (0.002± 0.001 ng/ml, p˂0.001) In addition the value of histamine was observed high in asthmatic patients (8.511± 0.410 ng /ml)while the control group was (2.565 ± 0.140 ng/ ml) with a significant difference of the mean value of histamine between asthmatic patients and control group (p˂0.001). LOX - 5 level in serum of asthmatic patients was higher (11.080 ± 0. 190 ng/ml) than in control group (9.821 ± 0.203 ng/ml, p˂0.001.The data revealed significant high mean value of LTA4H in asthmatic patients (24.148 ± 0 .450 ng/ml) compared with control group (18.912 ± 0.459 ng/ml, p˂0.001).The result showed that histamine level was increased in the group (>40 years) with a mean value (9.67 ± 4.25 ng /ml ) . While LOX - 5 showed high mean value (11.532 ± 1.274) in the group 20 - 40 years . Also LTA4H enzyme showed high mean value (25.54 ± 3.504 ng/ml)in the group 20 - 40 years , while serotonin appeared with high mean value (0.027± 0.015 ng/ml) in the group (< 20 years) with a significant difference between levels of these variables in each age group (p ˂ 0.001)The mean concentration of an antioxidant, Glutathione(GSH), and Malondialdehyde (MDA) in serum of asthmatic patient and control groups. The mean concentration of MDA increased in asthmatic patients (11.317 ± 1.096 μmol/l) more than control group(8.733 ± 3.756 μmol/l)with a significant difference between these groups (p < 0.05). The mean concentration of GSH increased was in the control (5.106 ± 3.197 μmol/l) more than asthmatic patients(3.905 ± 1.638 μmol/l, p < 0.05).According to the results of the present study, the mean activity of catalase(CAT) was higher (1.555±0.982 U/l) in asthmatic patients when compared with control group(1.173 ± 0.502 U/l, p < 0.05).The current study also concerned with the extrection of lipoxygenase from serum of asthmatic patient and healthy men by taking 15 ml serum from ten asthmatic patients men and 15 ml from serum of ten healthy men. And these quantities of serum were precipitated by ammonium sulfate, The best ratio for precipitating serum and extraction of enzyme is 60%. The anion exchange chromatography was used for extraction of the enzyme. The molecular weight of the extracted enzyme was determined by SDS - PAGE . In this procedure one subunit of the extracted LOXs enzyme showed a molecular weight of 35KD for one chain while a recombinant pure human LOX - 5 showed a molecular weight of 38 KD. The current study used NATIVEN technique for purification of the extracted enzyme obtained from ion exchange chromatography.The results revealed the optimum pH and temperature for LOXs activity and they were 8 and 40°C, respectively.The velocity constant and maximum velocity of the extracted Lipoxygenase enzyme was detected by using PHYWE SYSTEME GMBH SYSTEM, this system had the ability to obtain the relationship between conductivity and concentration (an increase in concentration lead to an increase in conductivity).The extracted lipoxygenase enzyme Km was 2.2mM and Vmax= 140mM/min in asthmatic patients and Km was 2.7mM and Vmax= 135mM/min in controls (by applying Michaelis - Menten equation).While the enzyme Km= 5.5mM and Vmax= 238mM/min in asthmatic patients and Km= 5 mM and Vmax= 208 mM/min in controls (by applying Lineweaver - Burk equation).The extracted LOXs from asthmatic patients and controls was treated with montelukast. The Km and Vmax appeared to have low values Km 3.6mM and Vmax 153mM/min and Km 3.7mM and Vmax 147mM/min, respectively. Also the extracted LOXs from asthmatic patients and controls was treated with molsiodomine, showed low values Km 4.4mM and Vmax 182 mM/min and Km 4.3mM and Vmax 166 mM/min, respectively.

Abstract: تدعم شبكة المركبات العديد من التطبيقات التجارية كانظمة النقل الذكية (ITS)، ولكن كان الدافع الاساسي وراء هذه الشبكات هو سلامة اتصالات الطريق الذي تعتمد فيه كل مركبة على الرسائل المرسلة لها من قبل نظائرها من المركبات الاخرى والتي قد تكون ضارة. ان الطبيعة المتغيرة والديناميكية لطبولوجيا الشبكة يجعل بامكان اي مركبة مغادرة الشبكة والانضمام اليها في اي وقت سواء كانت هذه المركبات موثوق بها ام لا. لذا يجب ان تتمكن كل مركبة من تقييم المعلومات الواردة لها من المركبات الاخرى واتخاذ القرارات بشانها والاستجابة لتلك المعلومات. عليه فبدون انشاء اليه مناسبة لادارة الثقة فان الاتصالات في هذه الشبكات قد تكون عرضه للتهديد الامني، حيث توجب الانظمة الامنية ان ياتي الارسال من مصدر موثوق لذا فان الثقة والامن مفهومان مترابطان لا يمكن عزلهما.لم يتحقق حتى الان تطوير نماذج امنة تماما لهذه الشبكات، لذا يهدف مجال البحث الجيد الى استثمار معظم الطرق السابقة في المؤلفات للبحث عن اطار عام لوضع اساس متين لتطوير الية احتساب السمعة والموثوقية في شبكات المركبات. يدعم هذا العمل امن شبكات المركبات من خلال استخدام تقنية الخوارزمية الجينية بالاضافة لنظرية اللعبة لتطوير الية ثقة متعددة الخصائص. | VANET support many commercial applications such as Intelligent Transportation Systems (ITS), but the original motivation behind it was safety of road communications where each vehicle has to rely on messages sent out by peer vehicles, which might be malicious. The dynamic changing nature of network topology makes any vehicle to leave and join the network at any point of time whether these vehicles were trusted or untrusted. Therefore, each vehicle must be able to assess, make decisions and respond to information received from other vehicles. So without having a proper mechanism for trust management, communication in VANET might be prone to security threat. Security systems impose that the transmission come from a trusted source, so trust and security are two interdependent concepts that there cannot be segregated.The development of fully secure schemes for these networks has not been entirely achieved till now. So, a good research field aims to exploit most of the previous approaches in literatures looking for a general framework to put solid basis to the development of Distributed Trust and Reputation Mechanism for VANET. The work supports the security of VANET by using a genetic algorithm technique in addition with game theory to develop a multi - featured trust mechanism

Abstract: Security evaluation algorithms can be considered as one of the most important challenges in computer networks. This is because of the growing data sharing among all clients (users). Therefore, the security level evaluation aspect of cryptography systems is recently appeared to be very important.In this work, evaluations of (RSA and AES) encryption methods are carried out by using Fuzzy Inference System (FIS) and Adaptive Neuro - Fuzzy Inference System (ANFIS). The editor of MATLAB (2013) is employed in this study and it contains a hybrid ANFIS facility between the Artificial Neural Network (ANN) and Fuzzy Logic techniques.First of all, designing and programming software codes for the first encryption method (RSA) have been simulated according to its original algorithm. Consequently, executing the RSA algorithm to collect the data values is implemented for the following parameters (message length, execution time, length of key and cipher message entropy). These parameters have been considered in the proposed approaches. So, the RSA data is used as the bases of the FIS inputs. Then, all the training and testing data values have been collected from the proposed FIS and prepared to be used in the next step (the ANFIS). The number of training samples has been selected to be 100 values by executing special software programs. These values have been utilized as follows : opening the ANFIS editor; loading the training data; determining the main ANFIS parameters and training the data with the least error tolerance. Subsequently, the number of testing samples has been chosen to be also 100 values by implementing special software programs. Hence, the evaluations are observed and the characteristics of the ANFIS which attained the best tested results have been benchmarked. Similar steps to evaluate the RSA by using large key numbers are implemented except of utilizing the parameter (key length) to study the influence of the key value on security evaluations.

The proposed FISapproach confirmed that the RSA evaluation is successfully implemented to the ANFIS editor.All the previous steps are repeated for the AES encryption method except one difference. That is, the utilized parameters here are the (message length, execution time and cipher message entropy). Basically, two key values are determined for the AES, which equals to 128 bits. Likewise the RSA, the suggested procedures are applied to the AES and the proposed FIS approach confirmed that the AES evaluation is successfully implemented to the ANFIS editor.Finally, comparisons between this study and previous work, and between the RSA and AES are established. In addition, comparisons between the evaluated outcomes of the FIS and ANFIS have been investigated by using two statistical metrics.

Abstract: The wireless communication devices have witnessed rapid growth in the recent years. Such growth and its useful applications led to the appearance of new applications known as "machine - to - machine" (M2M) communications. M2M plays a big role in finding the best hopeful explanation to change the current and the future smart widespread requests. Most of the smart wireless devices may perform as servers, collection of data and/or delivering the data at real time to users in a certain collaborative fashion.M2M communication domain consists of a huge number of tiny nodes and gateway (or sink) that are suffer from suffer from resource constrains like power limitation, storage capacity, radio limitation, data processing, etc.. Thus, it is necessary to find methods to increase node's lifetime as long as possible and consequently the overall sensor network. M2M devices consume considerable amount of energy due to communication process comparing to other process. This process depends on message size and the distance between the sender and the recipient. Thus reducing the packet size and finding a low energy aware routing procedure is necessary to save nodes energy.This thesis adopted compressed sensing (CS) as a modern data compression technique, modified Gossip algorithm as a flat protocol and introduced hybrid Gossip based low energy adaptive clustering hierarchy (LEACH) protocols as a new hybrid routing algorithm. CS combined with LEACH protocol named LEACHCS and the results that are reported from LEACHCS showed that the communication process can be improved in term of the channel bandwidth (B.W) utilization, increasing network throughput and saving node's communication energy.Gossip data aggregation technique is a biologically inspired paradigm of contagion inspired from behavior of the disease infection process. Its procedure is based on the help of neighboring nodes and employs the randomization technique to form a chain of the intermediary nodes (route). The modification of Gossip based on the selection operation of the next node hop. This thesis introduced three versions of modifying Gossip : a) Modify Gossip named (DGossip), in which a chain of intermediary nodes can be formed according to the relative node's energy and relative nodes displacement to the sink instance of randomization technique in the original Gossip. b) The formation of intermediary nodes based on the relative energy of neighbor nodes and nearest node to the source node called EN_Gossip. c) A hybrid of EN_Gossip and EL_Gossip named ENL_Gossip is introduced as a new version. In ENL_Gossip, a chain of intermediary nodes is collected through alternating use of both EN_Gossip first then EL_Gossip starting from the source node till reached the sink.The results showed that the DGossip is significantly better than others in term of the average remaining energy of network and latency time (in terms of number of hops), while ENL_gossip outperforms the others in term of network's live time.A new hybrid algorithm is proposed which combined Gossip as a bio - inspired technique with LEACH as a hierarchical multi - hop routing algorithm called LEACHGossip algorithm. This algorithm uses LEACH for clustering configuration purpose, while Gossip applies for each CH (or normal node) that is away (do m) from the sink (or from its associated CH). The simulation results proved that it outperforms LEACH about more times in terms of congestion between CHs and BS, node still alive and energy saving. Thus, the above mentioned procedures can be considered as efficient communication protocols for M2M communication networks in term of energy saving.

Abstract: Automatic speech recognition (ASR) systems perform well when using a close - talking microphone, However, many environments (Hands - free) where the use of such microphones is undesirable for reasons of convenience. In a hands - free environment, the noise and reverberation degrade the accuracy of recognition. An enhanced approach using microphone array for speaker localization and enhancement of speech signal input to an automatic speech identification system was proposed. The proposed system using enhanced beamforming technique based on Minimum Variance Distortionless Response (MVDR) for speaker localization with multi - microphone arrays. The strongest output beam signal corresponding to selected microphone array, used for the speaker identification. The identification phase based on using Mel Frequency Cepstrum Coefficient MFCC for feature extraction and enhance LBG algorithm for speaker modeling.Speaker identification accuracy in using proposed method were compared with conventional beamforming method, It was found that the higher recognition accuracy than previous approaches, and in experiments using speech signals that were artificially corrupted by additive noise. The proposed system provided a consistent, improvement in recognition accuracy for several experiments in simulation environments. It is also showing the benefit of usingmicrophone array processing. The localization phase evaluated using SNR, showing enhanced ratio after applying enhanced beamforming that estimate speaker location. The results showing localization accuracy 96.8% and 98.1% recognition accuracy where achieved.

Abstract: The usage of Online Social Networks, such as Facebook and Twitterbecomes more and more popular in order to exchange and disseminate news andinformation in real - time. Twitter in particular allows the instant dissemination ofshort messages in the form of microblogs to followers. This dissertation exploresand examine the usage of how social networks, such as the microblogging toolTwitter, can help in the detection of spreading epidemics and reducing time delaybetween the emergence of disease and report sick to the health authorities suchas World Health Organization (WHO).Text classification has been used to classify the patients and non - patients(positive / negative). Sentiment Analysis (SA) and Linear Support VectorClassifier (LSVC) have been applied in the classification patients. In thisdissertation, four diseases have examined. Diseases that have most similarity intheir symptoms have been taken in order to classify patients based on theirsymptoms by applying a recommendation system techniques. Symptoms - basedHealthcare Recommender System is new approach in this work. It uses patientsymptominstead of user - item in traditional Collaborative Recommender System.Collaborative Filtering (CF) has been applied in order to recommend whichdisease the patient may has. CF shows an indicator that users on Social Networkshave not enough knowledge to mention all symptoms for specific disease, that’sled to classify patients to more than one disease according to common symptomsthat mentioned by patients.Geolocation of users that classified as patients has been extracted in orderto recommend health authorities that there is a certain area might has a beginningof spread disease. An implicit geocoding of users has been extracted by usingGoogle Maps Geocoding API to avoid neglecting those who don’t have explicitgeolocation.IISuspected areas has been weighted by computing a Confidence Factor(cFactor) of Tweet source whatever it comes from mobile or desktop. cFactorhelp in reducing time consuming into 29% of collecting and processing data.Weighted and Geographic Symptoms - based Recommender (WGSR) model hasbeen created detect, classify and visualize patients on the map.The accuracy of WGSR model reached to %94 in the classification andmore than %80 with the real reports of World Health Organization (WHO) whichrefers as a very good and can be improved for better results.

Abstract: للفترة من اذار 2014 الى اذار 2015 تم جمع 1300 عينة سريرية مختلفة (عينات ادرار ومسحات جروح وحروق وعينات دم ومسحات من الفم والاذن والعيون بالاضافة لعينات البراز والقشع) من اثنين من مستشفيات محافظة بابل (مستشفى الحلة التعليمي ومستشفى بابل التعليمي للنسائية و| During the period between March 2014 and March 2015, a total of 1300 clinical specimens (urine, wounds, burns, blood, throat, ear, eye, stool, and sputum) were collected from two hospitals in Babylon province; Al - Hillah Teaching Hospital, and Babylon Hospital for Maternity and Pediatric. All specimens were cultured and 10 Acinetobacter baumannii isolates were obtained from clinical specimens in a percentage of (0.76%) distributed in blood 1 (0.6%), urine 2 (1%), wound infection 1 (0.75%), burn 5 (0.85%) and throat 1 (2%). This study was conducted to determine the occurrence of carbapenem resistant A. baumannii isolates obtained from Hillah hospitals. Isolates were identified according to API20E system and further confirmed using PCR technique. Antibiotics susceptibility was assayed by using disks diffusion method according to CLSI recommendations. All isolates revealed positive results with rapid iodometric test indicting the ability of beta lactamase production. Phenotypic detection of carbapenemase production was performed using the imipenem - EDTA disk and modified Hodeg's test (MHT). Then isolates were subjected to monoplex PCR targeting blaOXA - 51, blaOXA - 23, blaOXA - 24, blaOXA - 58, blaIMP, blaSIM blaNDM - 1, blaNDM - 2 and blaVIM genes, as well as, efflux pumps genes. One of the identified isolates (10%) was found to be imipenem, meropenem and ertapenem resistant, this isolate gave positive result with the imipenem - EDTA disk and (60%) of isolates were positive to MHT. PCR experiments showed ; all isolates were harbored blaOXA - 51 gene, four (40%) isolates were harbored blaOXA - 23 gene, three (30%) isolates were harbored blaOXA - 24 gene, four (40%) isolates were harbored blaOXA - 58 gene, five (50%) isolates were harbored blaIMP gene, six (60%) isolates were harbored blaSIM gene, two (20%) isolates were harbored blaNDM - 1 gene, four (40%) isolates were harbored blaNDM - 2 gene, while none of these isolates harbored blaVIM gene. The present findings suggest that emergence of (OXA - 23, OXA - 24, OXA - 58, IMP, SIM, NDM - 1, NDM - 2) carbapenemase producing A. baumannii clinical isolates in Hillah City hospitals. Also there are indicative appearance of efflux pump genes ; (50%) for Ade - A and Ade - B each other, (40%) for Ade - C, (80%) for all of Ade - R and Ade - S, (100%) for all of Ade - I and Ade - J, and (50%) for Ade - Y. All isolates of A. baumannii appear as MDR, while only one appear to be as PDR. The trans - mobility of resistant genes was examined by trans - conjugation experiment ; the results indicated that only blaIMP and blaOXA - 23 genes were transferred horizontally in the current study. In attempting to investigate any blaNDM gene variation the results showed some different than NCBI - Blast A. baumannii blaNDM - 1 and blaNDM - 2 it may as a unique genotyping.These results revealed that carbapenemase producing A. baumannii were detected in both phenotypic and genotypic methods (PCR). This underlies the importance of their accurate identifications and reporting to prevent the emergence of complete resistance to the most potent drugs against A. baumannii in Babylon province.

Abstract: The study consists of three parts related with patients of CRC as in : 1 - Molecular part 2 - Cytogenetic and molecular genetics part and 3 - Immunological part. In addition of their relatives of clinical and pathological diagnosis, genus, and tumor locations in 150 of Iraqi patients confirmed with CRC collected from Teaching Hospitals of some Iraqi governorates. The percent of male to female (54.66% / 45.43%) and the aged range of study were 16 to 80 years.The first part consist a study of five types of genes related with CRC represented by MLH1, MSH2, APC, K ras, and SMAD7 genes. Some of these genes develop with germline mutations as in MLH 1 exons1 and 15 so as MSH2 genes. While the rest genes related with a sporadic of CRC. All these genes were amplified by conventional polymerase chain reaction (PCR) for study the types of the mutations and their defect of these genes on CRC. The APC exon11and K ras exon1 genes were processed by single strand conformational polymorphism (SSCP) technique. The results of PCR - SSCP technique for two genes represented by appeared three types of bands, which were (AA), (AB) and (AC) bands. The important band was (AB) which constitutes the variability region represented by 84.2% and 44.82% in patients for both genes. The results of patients with mutated bands with high significant differences(P?0.05).compared with healthy control. Patients carried these bands subjected to PCR - Sequences technique. The analysis results for APC gene sequences were substitutions mutations type of single nucleotide polymorphism (SNP) change Cytocine to Thiamin (C>T) at 1972 location of genome. While the analysis results of Kras gene appeared two types of mutations, substitution and frame shifts represented by deletion mutation and so as appeared stop codon mutation.The other genes represented by MLH1, MSH2, and SMAD detected by direct PCR - Sequences. The results analysis of MLH1 gene, exon (1and 15) represented by nucleotides change with high frequencies of substitution mutation through exon1 at different locations of nucleotides. So as frame shift mutation type deletion through exon15. While for MSH2 gene, exon 6 from 6.66% represent by deletion mutation. A spread study for SMAD7 gene, exon4 were done through 30 patients average age 52 years (male to female 56.7% : 53.3%) confirmed colorectal adenocarcinoma compared with 15 healthy. A mutation of 20% of (SNPs) were identified.The second part which represented standard conventional cytogenetic and molecular genetics were done through peripheral blood culture (PBC). The study showed increasing of mitotic index (MI) in patients with significant differences (P?0.05) compared with healthy controls indicating for increasing of proliferation of the lymphocytes division. The study showed some chromosomal aberrations with significant, the majority of aberrations were higher significant in dwarf and aneuploidy chromosomes so as elongation chromosomes revealed significant differences (P?0.05) between patients and healthy. The appeared of Polyploidy chromosomes, with significant differences (P?0.05), that’s seem to be good indicator for cancer disease. The molecular genetics alterations which dependent on cytogenetic investigation were done through deletion of long arm of 5 chromosome which APC gene is located. The test elucidates the importance of inactivation (deletion) of APC gene in elicited of colorectal cancer. The study of 20 patients, were investigated by fluorescent in situ hybridization (FISH). The results showed 60% patients which have 5q arm deletion of (+). And (5%) have two deletions (++) which was a male aged less than 60 years. The results analysis explained significant differences (p?0.01) between studied group and deletion (+) of arm 5q. A correlation represented by significant differences (p?0.01)through dysfunction of APC gene deletion of 5q were found with high percent among sporadic adenocarcinoma 58.3%, with less in attenuated familial adenomatous polyposis (AFAP) and familial adenomatous polyposis (FAP) represented by the (25%), and (16.7) respectively.The last part related with immunological test were done by detection of tumor markers represented by Carcino Embryonic Antigen (CEA), IL - 33 and IL - 31.These markers represented a confirmative indicators for colorectal adenocarcinoma which were tested by ELISA technique in (79) patients confirmed with CRC of male and female. These tumor markers in tested with patients showed high significant differences (p?0.01) compared with healthy controls. Another immunological test for detection of Human papilloma virus (HPV) type 18 E6 gene expression in CRC by Immune histochemistry technique (IHC) in 71 (FFPET) of CRC. The results of this study showed there were a correlations between patients and adenocarcinoma positive HPV18 E6 infection 43.7% of patients infected with virus, with high significant differences (p?0.01) and higher infection in female (67.7%) than male (32.3%). So as a correlations were found between HPV18 E6 expression and tumor tissue locations, explained by high percentage 45.2% in rectum.While a tumor marker was (CD8+) was used to determine its role in human immune surveillance in tumor regions of CRC so as with regions which were infected by HPV. The study revealed high significant differences between healthy control and studied groups which have (CD8+) positive infiltration in tumor origins through detection by (IHC).In conclusions diagnosis of CRC can be detected by special genes like K ras gene through professional PCR processing, compact with tumor markers, so as Fluorescent in situ hybridization (FISH) technique provides a precise method which can be used for detection of alteration of molecular and cytogenetic related with CRC.

Abstract: صممت الدراسة الحالية لتوصيف الانماط الجزيئية والمظهرية للنمو والفعالية الانزيمية للانزيم المحلل للبروتين والتنوع الوراثي وعلاقته بالتعبير الجيني بين عزلات الفطر الجلدي.Trichophyto rubrum ولهذا الغرض جمعت 150 عينة سريرية (قشطات جلدية (80), اجزاء شعر (60) | The present study was designed to characterize the morphological and the molecular patterns of growth, enzymic activity of proteases, genetic diversity and their correlation with gene expression among strains of Trichophyton rubrum. For these purpose, A total of 150 clinical specimens (skin scrapings (80), hair fragments (60) and nail clippings (10)) were collected from 100 patients (70 males&80 females) whom clinically diagnosed with dermatophytosis after attendingto the dermatology and venereal diseases centre of Mergan Teaching hospital and private clinic in Babylon city from Feb. 2014 to May 2014. T. rubrum were isolated and identified using cultural, biochemical and physiological tests. Isolates were then subjected for confirmation by PCR, genotyping using RFLP - PCR, sequencing and registration of these sequences in GeneBank for obtaining accession numbers then phylogeny. The growth conditions, were tested, in addition to, the genetic expression of proteases (exocellular protease and endocellular aminopeptidase) were determined using Real - Time PCR. Out of 150 specimens, 24 (16%) isolates were dermatophytic fungi and only 5 (20.8%) of them belong to T. rubrum. The influence of cultural conditions in growth of T. rubrum showed that the 30 ?C, pH 6, SDA medium and 7 days incubation were the optimal conditions for its growth. Proteolytic activity of isolates of T. rubrum against casein as a substrate revealed an ability to produce protease in solid and liquid media after 14 days of incubation. This activity was varies according to the type of isolate where the isolate No.1 (isolated from skin) gave a high proteolytic activity (5.6cm) in solid media and (80.1U/ml) in liquid media in comparison with other tested isolates (No.2 - No.8). on the other hands, the 9 days of incubation, 30 ?C, pH 7 and 0.5% substrate concentration were the optimal condition for proteolytic activity of these isolates. The molecular tests confirmed that all tested isolates belong to T. rubrum with amplicon size (601bp) after amplification of ITS1 primers using PCR technique. While the RFLP - PCR technique showed the presence of two genotypes (I%II) belong to T. rubrum with subgenotypes (Ia - Id) and (IIa - IId) respectively. The relative quantification of proteolytic activity (exocellular protease and endocellular aminopeptidase) produced by T. rubrum genotypes were expressed by using Real - Time PCR after amplification of the target gene of ptotease and aminopeptidase in comparison with housekeeping gene (? - actin) as a reference gene. The results showed the up - regulation of gene encoded to exocellular protease than the down - regulation of endocellular aminopeptidase produced by T. rubrum in the presence of casein as a substrate. The internal transcribed spacer 1, partial sequence, 5.8S ribosomal RNA gene and internal transcribed spacer 2, complete sequence and 28S ribosomal RNA gene, partial sequence of local isolates of T. rubrum were used for sequencing, registration in Genebank - NCBI and phylogeny. Five accession numbers were recorded and available to NCBI, EMBL in Europe and the DNA Bank of Japan. These accession numbers were : KP979787, KP979788, KP979789, KP979790, KP979791. Phylogenetic relation between local strains and world strain showed a high identicasl with T. rubrum (GQ376105.1). This is the first study in Iraq which employed sequencing, registration of sequences in Genebank - NCBI and carrying out phylogeny of local and world strains of T. rubrum.

Abstract: الحمى المجهولة من الامراض الواسعة الانتشار في العالم تحدث بسبب جرثومة الكوكسيلا بيرنتي.هذه الجرثومة تسبب عدة امراض الاجهاض هو الاكثر حدوثا. المخاطر البيولوجية وانشار هذه البكتريا على النساء المجهضة والحيوانات في العراق غير معروفة. لذلك هدفت هذه الدراسة ال | Query fever is a worldwide distributed disease caused by Coxiella burnetii bacteria causes several disease main of this disease is abortion, the biological hazard and prevalence of this bacterium on the aborted woman and small ruminants are not known in Iraq. Therefore this study was aimed to detection and isolation of Coxiella burnetii as a causative agent of abortion in woman and female of small ruminants.352 samples were collected includes human samples and animals samples. A total of 120 blood aborted women, 7 breast milk samples, 20 placental samples and 50 blood samples from normal women as control groups, these samples collected from Bent Al - Huda hospital in Thi - Qar province. Animals samples, a total of 80 aborted animal blood samples, 15 milk samples, 10 placental samples and 50 blood samples, these samples from normal animals as controls group, these samples collected from veterinary hospital in Thi - Qar province. The results of this study showed a high incidence of abortion occurs in first trimester of gestation (41.666%) and high incidence in rural regions (64.16%) and also age group from 21 to 30 years old (50%).The methods used for detection of Coxiella burnetii includes serology tests, polymerase chain reaction (PCR) technique for confirmation serological test and isolation on embryonated chicken eggs and detection by PCR technique. Out of the 120 women serum samples analyzed by enzyme ELISA, the results of percentage of anti - Coxiella burnetii IgM and IgG in human samples were 36 (30 %). The percentage of anti - C. coxiella IgM in human samples were 10 (8.333%), while the percentage of anti - C. Coxiella burnetii IgG in human 26(%21.667%).. In animals total of (80) serum samples, the percentage of anti - C. coxiella IgM and IgG in animals' serum samples were 31(38.75%) The percentage of anti - Coxiella burnetii IgM in animals 10 (12.5%), while, the percentage of anti - C. coxiella IgG in animals are 21(26.25 %). PCR technique used for identification of Coxiella burnetii in human and animals samples by targeting three genes including outer membrane protein (com1 and com2), 16S rRNA and transposase insertion element (IS1111) genes. In human blood samples the com1 and com2 genes detected in 23of 120 (19.166%) samples and in breast milk samples 1 of 7 (14.28%). and not detected in placental samples. The 16S rRNA gene was detected in 16 of 120 blood samples (13.33%) and in breast milk samples and placental samples were not detected. The IS1111 gene was detected in 9 of 120 blood samples (7.5%) in human blood samples, also were not detected in milk and placental samples.. In animals blood samples the com1 and com2 genes were detected in 19 of 80 blood samples (23.75%) and were not detected in milk and placental samples. The 16S rRNA gene detected in the same percentage of com1 and com2 genes 19 of 80(23.75%) and in the milk samples and placental samples not detected. The IS1111 gene detected in 10 of 80 (12.5%) in animal blood samples, also were not detected in placental samples. An isolation of Coxiella burnetii which identified by ELISA and PCR via inoculated Coxiella burnetii buffy coat samples in embryonated chicken eggs from 6 to7 days old and then completed an incubated to 10 - 15 days, harvested yolk sac contains then detecting Coxiella burnetii by PCR. The results of PCR after inoculation of (43) samples were positive in PCR (100%). Statistical analysis revealed no significant different between ELISA test, PCR and isolation results in human and animals samples. These mean that we can use the ELISA in the primary diagnosis. The correlation coefficient was highly significantly between human and animal samples at 0.01%.
