Alabaster and Selenite Gypsum:I-Dehydration-Rehydration Comparison Studies

引用

Journal of Materials Science & Technology 2002年第4期18卷 365-368页

作者： El-sayed LAl-WakeelChemistry Department, Faculty of Science, Suez Canal University, Ismailia, Egypt Suez Canal Univ Fac Sci Dept Chem Ismailia Egypt

Two types of gypsum raw materials, selenite and alabaster, were used to prepare dental stone (a-hemihydrate). Gypsum lumps (0.8~2.5 cm) were hydrothermally treated at 135, 160 and 180癈 for 6, 2 and 1 h respectively. The physicochemical properties and composition characteristics of the a-hemihydrates prepared from selenite and alabaster raw gypsum were determined. The results indicated that both the selenite and alabaster raw gypsum show the same chemical and mineralogical composition of calcium sulphate dihydrate. They differs only in their microstructure, selenite raw gypsum exhibits perfect regular crystals while alabaster gypsum, on the other hand, exhibits irregular, large size and interlocked crystals. Selenite is more accessible to dehydration than alabaster raw gypsum. The a-hemihydrate samples prepared from alabaster raw gypsum showed a very short setting time and a lower compressive strength values in relation to that prepared from selenite gypsum. The compressive strength values of the all prepared samples were higher than that specified by A.D.A specification for dental use. To optimize the setting time of both products further studies are needed.

Study of angiotensin converting enzyme and genotype among Egyptian preeclampsia patients

American Journal of Molecular Biology 2014年第1期4卷 26-36页

作者： hassan A. Alsokary Mostafa A. Kamel Sameh S. Sadek nermine h. Zakaria Iman A. Abdel Fatah Clinical Pathology Department Faculty of Medicine Alexandria University Alexandria Egypt Obstetrics and Gynecology Department Faculty of Medicine Alexandria University Alexandria Egypt

Preeclampsia is a frequent disorder with reported incidence in pregnancies. In Egypt, it complicates 6%-8% of pregnancies and reaches 15% in referral centers. The renin-angiotensin system activation during the early stages of Preeclampsia proved to be a direct cause. Women carrying the D allele of the ACE-I/D polymorphism have higher measures of uterine artery resistance, which is a marker for development of intrauterine growth retardation and preeclampsia. The maternal syndrome of preeclampsia (PE) during the latter half of pregnancy is believed to result from impaired placentation in early gestation and a failure to develop low resistance uteroplacental circulation. Aim: The aim of this study was to evaluate the association with angiotensin converting enzyme gene polymorphism and changes in its enzyme serum level in preeclamptic patients compared to non preeclamptic control group together with studying the changes in umbilical artery and uterine artery Doppler. Subjects: The study was conducted on 180 pregnant women allocated into two groups having the same inclusion and exclusion criteria except for hypertension and proteinuria;each group comprised of 90 pregnant women with matched age. Methods: Doppler study of umbilical and uterine arteries and the detection of Angiotensin converting gene polymorphism by PCR with Estimation of serum ACE in serum by ELISA technique. Results: The distribution of the ACE-I/D genotypes and allelic frequencies in the present study of polymorphism was 37.8% for the DD, 48.9% for the ID, 13.3% for the II in preeclampsia group while it was 33.3% for the DD, 46.7% for the ID, and 20% for the II in the control group. There was no significant difference between cases and controls regarding the cumulative D effect. Conclusions: No existence of a relation between preeclampsia and ACE gene polymorphism considering different modes of inheritance whether is dominance or recessiveness. No effect of ACE gene polymorphism is on ACE serum level. P
