The Association of Prothrombin Gene Mutations and Cytomegalovirus Infection with Abortion Among Iraqi Women

يُصنف الإجهاض على أنه إنهاء الحمل الناجم عن فشل أو إزالة الجنين من الرحم قبل إتمام الحمل. هناك عوامل مختلفة ترتبط بالإجهاض منها الكائنات الحية الدقيقة والعوامل الوراثية. ان الفيروس المضخم للخلايا هو أحد مسببات العدوى الفيروسية الخلقية التي تصيب مجموعة واسعة من الأشخاص. يعتبر جين البروثرومبين (معرف الجين: 14061 في NCBI) أحد الأسباب الأساسية التي تؤدي إلى تخثر الدم ووظيفة الإجهاض، وبالتالي فإن الهدف من الدراسة هو اكتشاف وربط الفيروس المضخم للخلايا وطفرة جين البروثرومبين بالإجهاض من خلال الأساليب الجينية والمناعية.  تم جمع 5 مل من حجم الدم الكامل من خلال وخز الوريد وتم تقسيمها إلى أنبوبتين، أحداهما تحتوي على EDTA والأخرى دون (أنبوب عادي) من 74 امرأة لديهن تاريخ إجهاض كمجموعة مريضات و74 امرأة بدون سجل إجهاض مع واحد على الأقل من الخصوبة الناجحة كمجموعة تحكم. تُستخدم PCRs الخاصة بأليل لتضخيم مناطق الجينات باستخدام بادئات جينية تحتوي على تعدد أشكال جينات البروثرومبين.أظهرت النتائج الحالية أن أكبر خطر للإجهاض لوحظ في النساء المصابات بتفاعلية مصلية IgG في 65 امرأة مع تردد (87.8٪) وكان أقل معدل للإجهاض في إيجابية مصلية IgM في 3 نساء بمعدل تكرار (4.1٪) و6 (8.1٪).) كانت إيجابية لـ IgM-وIgG يشير إلى امتلاكهم عدوى قديمة وحديثة. علاوة على ذلك، تُستخدم PCRs الخاصة بالأليل لتضخيم تعدد الأشكال البروثرومبين G20201A. أظهرت نتيجة هذه الدراسة عدم وجود علاقة بين تكرار مستوى النمط الجيني للبروثرومبين والإجهاض في النساء المصابات بفيروس CMV. في حين أن هناك علاقة ارتباط ذات دلالة إحصائية بين مجموعات الأليلات A وG والإجهاض في النساء المصابات بفيروس CMV.Abortion is categorized as the termination of conception caused by the failure or removal of the embryo from the uterus before the conclusion of pregnancy. Microorganisms and genetic factors are two of the many factors associated with abortion. Cytomegalovirus is a widespread congenital virus infection pathogen that affects a wide variety of people. The prothrombin gene is one of the essential causes that trigger blood clotting and the function of abortion women, therefore the aim of the study is to detect and associate Cytomegalovirus and prothrombin gene mutation (Gene ID: 14061 in NCBI) with abortion through genetic and immunological methods. Five ml of whole blood was collected from an intravenous puncture and divided into two tubes, one with EDTA and one without (plain tube) from 74 women with an abortion history as a patient group and 74 women without an abortion record who had at least one successful fertility as a control group. Allele-specific PCRs are used to amplify gene regions with genetic primers containing prothrombin gene polymorphisms. Current results have shown the greatest risk of abortion was observed in women patients with IgG seropositivity in 65 women with frequency (87.8%) and the lowest rate of abortion was in IgM seropositivity in 3 women with frequency (4.1%) and 6 (8.1%) were positive for IgM-and IgG indicating they have both an old and recent infections. Furthermore, allele-specific PCRs are used to amplify prothrombin G20201A polymorphism. The result of this study demonstrated there is no association between prothrombin genotype level frequency and abortion in CMV-infected women. While, there is a highly significant association between A and G Alleles combinations and abortion in CMV-infected women

Optical Investigations of CdSe1-x Tex Thin Films

The alloys of CdSe1-xTex compound have been prepared from their elements successfully with high purity (99.9999%) which mixed stoichiometry ratio (x=0.0, 0.25, 0.5, 0.75 and 1.0) of (Cd, Se and Te) elements. Films of CdSe1-xTex alloys for different values of composition with thickness(0.5?m) have been prepared by thermal evaporation method at cleaned glass substrates which heated at (473K) under very low pressure (4×10-5mbar) at rate of deposition (3A?/s), after that thin films have been heat treated under low pressure (10-2mbar) at (523K) for two hours. The optical studies revealed that the absorption coefficient (?) is fairly high. It is found that the electronic transitions in the fundamental absorption edge tend to be allowed direct transition. It was also found that the optical energy gap vary non-linearly with composition (x) and have a minimum value at x=0.5 and increases after heat treatment. It is found that the optical constants vary non-linearly with composition, and the behavior inverse at x=0.5, and affected by heat treatment. The behavior of ?1 is similar to the behavior of n, while the behavior of ?2 is similar to the behavior of k

Microwave Assisted Synthesis, Characterization and Biological Study of Some Chalcone Compounds Derived from Phenyl Isothiocyanate

Chalcones are synthesized by Claisen-Schmidt condensation, which involves cross-aldol condensation of appropriate aldehydes and ketones by base catalyzed reaction, the new chalcone derivatives synthesized by the reaction aldehyde with their compounds. By microwave assisted synthesis, a considerable increase in the reaction rate has been observed and that too, with better yields. M.P., TLC, CHN, FTIR, NMR and MS spectroscopy has characterized all the synthesized compounds. The biological screening data of the synthesized compounds were also studied. Keywords: microwave, chalcone, antibacterial. DOI: 10.7176/CMR/11-3-05 Publication date:March 31st 201

Newly Discovered RR Lyrae Stars in the SDSSXPanXSTARRS1XCatalina Footprint

We present the detection of 6,371 RR Lyrae (RRL) stars distributed across ~14,000 deg^2 of the sky from the combined data of the Sloan Digital Sky Survey (SDSS), the Panoramic Survey Telescope and Rapid Response System 1 (PS1), and the second photometric catalogue from the Catalina Survey (CSDR2), out of these, ~2,021 RRL stars (~572 RRab and 1,449 RRc) are new discoveries. The RRL stars have heliocentric distances in the 4--28 kpc distance range. RRL-like color cuts from the SDSS and variability cuts from the PS1 are used to cull our candidate list. We then use the CSDR2 multi-epoch data to refine our sample. Periods were measured using the Analysis of Variance technique while the classification process is performed with the Template Fitting Method in addition to the visual inspection of the light curves. A cross-match of our RRL star discoveries with previous published catalogs of RRL stars yield completeness levels of ~50% for both RRab and RRc stars, and an efficiency of ~99% and ~87% for RRab and RRc stars, respectively. We show that our method for selecting RRL stars allows us to recover halo structures. The full lists of all the RRL stars are made publicly available.Comment: 14 pages, 11 figures.

Seatbelts and road traffic collision injuries

Modification of seatbelts and their legislation played an important role in reducing morbidity and mortality of occupants in road traffic collisions. We aimed to review seatbelt development, its mechanism of action and its effects. Seatbelts reduce injury by preventing the occupant from hitting the interior parts of the vehicle or being ejected from the car. We have made a linear regression correlation between the overall seatbelt compliance and road traffic death rates in 46 high income countries to study the relationship between seatbelt use and mortality. There was a very highly significant negative correlation between the seatbelt compliance and road traffic death rates (R = - 0.77, F = 65.5, p < 0.00001). Seatbelt-related injuries include spinal, abdominal or pelvic injuries. The presence of a seatbelt sign must raise the suspicion of an intra-abdominal injury. These injuries can be reduced if seatbelts were applied correctly. Although seatbelts were recognized as an important safety measure, it still remains underused in many countries. Enforcement of seatbelt usage by law is mandatory so as to reduce the toll of death of road traffic collisions

Investigation of para-sulfonatocalix[n]arenes [n = 6, 8] as potential chelates for 230U

International audienceLiterature reports of the efficacy of para-sulfonatocalix[6]- and calix[8]-arenes as U(VI) complexants indicated that they might be useful for in vivo chelation of the novel therapeutic alhpa-emitter 230U. We have studied the complexation of U(VI) with para-sulfonatocalix[6]arene and para-sulfonatocalix[8]arene by time resolved laser induced fluorescence spectroscopy and using competition methods with Chelex resin and 4-(2-pyridylazo)resorcinol in simplified and in biological media. New thermodynamic parameters describing the stability of U(VI)-para-sulfonatocalix[n]arene [n = 6, 8] complexes were obtained. Although the interactions are strong, the complexes do not exhibit sufficient stability to compete with carbonate ions and serum proteins for complexation of U(VI) under physiological conditions

Structural and optical properties Investigation of ZnxCd1-xS thin films

CdZnXS1-X thin films with different composition have been deposited on glass substrate by by the spray pyrolysis method at RT using CdCl2 (0.1M),ZnCl2(0.1M)and H2NCSNH2(0.1M)solution and a substrate temperature of ( 400±20°C). X-ray diffraction studies reveal that the films are polycrystalline in nature with hexagonal structure and preferential orientation along (002) . The grain size of the films is found to increase form  (37.397 to 46.902) nm with increasing Zinc concentration while the strain and the dislocation density of the films are found to decrease from (7.15 to 4.54) 10 4 rad and from (3.82 to 1.93) 10 14 lines.m-2 respectively . The  transmittance  spectrums  of  CdZnxS1-x  thin  films  reveal very pronounced interference effects for photon energies below the fundamental absorption edge by exhibiting interference pattern . The optical energy gap for CdZnxS1-x thin films increases and shifts towards the UV region  as the  Zn concentration in the films increased .Â

Effect of Some Medicinal Plants on the Activity of Some Immunological Factors in Saliva and Serum of Type –?? Diabetics

The study involved 45 male and 45 females of diabetic patients type- ?? aged from 40-69years , and with the same numbers of males and females for control , all the patients and controls were without any periodontal diseases and without any systemic disease. Diabetic patients were divided in to three groups according to the degree of periodontitis , and the inflamed gingiva of all groups of diabetic patients were treated with the dried fruits powder (crude) of medicinal plants Quercus robur , Thuja occidenalis , Terminalia chebula, Anethum graveolens , respectively and mixture. Some immunological and antimicrobial factors (IgA, Lactoferrin , Lysozyme ) , were detected in serum and saliva of diabetic patients and the controls , the results revealed that the level of IgA , Lysozyme in saliva were more than in serum of the control , and this will insure that these factors are considered to be generally protected against bacteria in the oral cavity . Also there was a significant increase at (p?0.001) especially after treatment with the mixture of medicinal plants , so that the mixture of these plants can be considered the best type in the treatment of inflamed gingiva of type –?? diabetic patients
