Abstract

Background: Gestogens have been recommended to have a place in the prevention of threatened miscarriage and spontaneous pregnancyloss during the first 3 months of pregnancy. Certain studies consider that this steroid hormone has genotoxic effect because they directlyinvolved in the change of DNA structure. Objectives: This study aims to investigate the cytogenetic effects of gestogens on peripheral bloodlymphocytes of pregnant women, by damaged cells and chromosomal aberrations, as well as evaluate the models for hormonal therapy in vivo.Materials and Methods: Blood sample from 30 women with threatened miscarriage, who received gestogen therapy in the first 3 months, Weretaken. Cytogenetic analyses and karyotyping were performed for Each patient Before and after therapy. Results: The numerical chromosomalaberrations which found in blood lymphocytes of women before taking gestogens were 44,XX and 48,XX. The same result was observed aftertaking gestogens. The percentage levels of structural chromosomal aberrations were ring chromosome (2.06%), chromatid breaks (12.47%),chromatid gaps (1.65%), dicentric (0.55%), acentric chromosome (4.02%), and interchange chromosome (12.5%). Whereas, the abnormalitiesafter treatment with gestogens were ring chromosome (5.31%), chromatid breaks (42.19%), chromatid gaps (20.86%), dicentric (7.50%),acentric chromosome (17.75%), and interchange chromosome (43.97%). Conclusion: Gestogens as hormonal substitute therapy do notinduce numerical chromosomal aberrations but have a significant increase of structural chromosomal aberrations Gestogens have genotoxiceffects on human lymphocyte chromosomes at wide range of concentrations. So the potential benefits and side effects of it must be weighedup against the deleterious effects.

Abstract

In this paper, necessary and sufficient conditions for oscillation are obtained, so that every solution of the linear impulsive neutral differential equation with variable delays and variable coefficients oscillates. Most of authors who study the oscillatory criteria of impulsive neutral differential equations, investigate the case of constant delays and variable coefficients.However the points of impulsive in this paper are more general. An illustrate example is given to demonstrate our claim and explain the results.

Abstract

In the present study, the influence of various solvents on UV-VIS absorption spectra of N,N-Bis(salicylidene)ethylenediamine (Salen) has been investigated. Salen ligand has two absorption maxima (around 260 and 320 nm). To explain the obtained spectra, the frequencies and molar absorptivity values were combined with solvent properties using a total solvatochromic equation suggested by the Kamlet and Taft. The multiparametric examination denotes that non-specific dipolar interactions of the solvents (π*) with the solute play a significant role in absorption maxima in pure solvents. The ionization constant (pKa) of salen in methanol has been determined by spectrophotometric measurements. Two graphical methods have

Abstract

In this work, the electro-optical effects of two types of liquid crystal; pure liquid crystal (LC) and liquid crystal doped with cobalt nanoparticles (LC/Co) were studied. The difference between the two types those been jabbed led to different values of electro-optic properties because of the different susceptibilities of the materials. It was seen that the LC with cobalt nanoparticles was more responsive to the applied electric field owing to the nature of the constituent material (electric material) than the pure LC. The response time of the doped LC is greater than the response time of the pure LC, which makes the doped LC is the best in the optical switching applications.

Abstract

The Creative right is a kind of right that gives the owner the ability to creat an effect on others that includes the modification, termination or creation of alegal status for others , and third parties to comply and submit to this effect. Islamic jurisprudence knowns middle status that corresponds to the Creative right in jurisprudence. The Creative right is a degree of right, but less of a scope and content than the ordinary right because it does not creat an obligation on others.

الحقُّ المُنِشئ هو نوع من انواع الحق، يخول صاحب الحق وبإرادته المنفردة، القدرة على إنشاء أثر تجاه الغير يتضمن تعديل مركز قانوني قائم او انهاءه او خلق مركز جديد للغير، وما على الأخير سوى الامتثال لهذا الأثر المنشئ. والفقه الاسلامي يعرف المنزلة الوسطى التي تقابل الحقَّ المُنشِئَ في الفقه القانوني. ويعد الحقُّ المُنشِئُ درجة من درجات الحق، فهو أقل نطاقاً ومضموناً من الحق العادي، لأن الحق المنشئ لا يفرض التزاماً على الغير بعكس الحق العادي الذي يرتب التزاماً على الغير.

Abstract

The Companions of the Prophet(PBUH) have a very decisive role in displacing the legislative nature of the divine texts by substituting it with solid foundation after the death of the Prophet(PBUH). It resulted in a political reality which was far from the principles of Islam. The successive Rulers of the Islamic nature produced theories and principles which had religious connections to justify their strong hold of the throne. One of these theories is the Divine authority with its crown prince succession of the relatives of the Prophet(PBUH) raised by the Abbasside. It was the root of all the consequences of the events of the shede

إنّ الدور المميز والواضح لأصحاب الرسول (صلى الله عليه وآله وسلم) في إزاحة الواقع الشرعي القائم على النصية السماوية وإبداله بنصية أرضية تقوم عليها الأسس الحكمية بعد وفاة الرسول (صلى الله عليه واله وسلم) ، انتج واقعاً سياسياً بعيداً عن قيم الاسلام ومبادئه فقد عمد الحكام المتعاقبون على حكم الامة الاسلامية الى انتاج نظريات ومفاهيم سياسية لها ارتباطات دينية لتكون مبرراً حكمياً ملزماً للامة للتمسك بحكمهم وعدم الخروج عليه مهما كانت ممارساتهم ، منها ايجاد نظرية التفويض الإلهي التي كانت واحدة من متبنياتها ولاية العهد ثم قرابة الرسول ( صلى الله عليه واله وسلم) التي نادى بها الحكام العباسيون ، ان الجذر الحقيقي لكل ما حصل من تبدل سلطوي وشرعي يمكن إرجاعه إلى ممارسات الأصحاب إلازاحية والتبريرية بعد أحداث السقيفة وما تلاها .

Abstract

The aim of this study to detect the total anti- oxidant capacity (TAC) level and DNA damage by use alkaline comet assay in different measurements as biomarker of double and single strand breaks that caused by smoking and relation with age of individuals exposed to ionizing radiation, this study including 100 male blood samples (30-65) years, TAC level were measured as biomarker for detecting the effect of smoking and age of exposed individuals, in this research recorded non- significant increase in total TAC level in blood serum for the non-smoker individuals as compared with smoker, in other hand also we recorded non -significant result of TAC in three age groups (Less than 40, 40-50 and more than 50) years, but the single cell gel electrophoresis ( comet assay) appear highly significant increase ** (P<0.01) with Mean ±SE (18.63± 0.72) and LSD –value (3.386 **) of DNA damage(high damage measurement HD) in smoker individuals when compared with nonsmoking, the present study shows significant difference in comet high damage cells (* P<0.05) for some age groups that be less than 40 and more than 50years is 12.67 and 17.37 respectively, the study results show that the difference increased of comet assay measurements may be caused by smoking , aging and also effect of works environment. The level of TAC was non more difference in age groups and in smoker individuals or non- smokers . In conclusion, found that an negative correlation between TAC level and oxidised bases that measured by comet assay (single and double strands breaks), and age. This study , indicated that can use the different measurement of comet assay as biomarkers to detect influence of age and smoking in peripheral blood lymphocytes DNA. Also, the results confirmed usefuless of the TAC as biomarker of smoking and aging effect in exposed individuals.
