Objective:To assess the anion gap (AG) validity in prediction the goat's fertility before ***: This study was carried out on two groups (20/20, aged 4–6 years and weighted 30–43 kg) of pluriparous pregnant Baladi goats. Animals were subjected to clinical examination, blood sampling to assess serum biochemical parameters in correlation with utrasonographic assessment of uterine horn involution (UTI) and placental dropping time after kidding. Unpaired studentt–test was used to detect the significance of differences (Pmong the different assessed parameters, analysis (r) was assigned atPme statistics ***:Results revealed that there were highly significant differences (Pmally and abnormally parturated goats concerning Cl–, K+, Na+, P, mg2+, Total/Ca2+, albumin, glucose and AG. Goats suffered from dystocia having high levels of HCO3–, cortisol and lactate. Additionally, there were significant differences (Pmally and abnormally parturated goat does regarding the process of UTI starting from 3rd to 10th wk after parturition. Furthermore, there was a highly significant difference (Pmally and abnormally parturated goat does concerning their placental dropping time;where, distressed/abnormally parturated goat having the longest time. Furthermore, there were highly strong correlation coefficient between mg2+, K+, Na+, HCO3–, glucose, albumin, AG and corrected AG concentrations during goat's prepartum period and UTI, placental dropping ***:Reporting serum bio-chemical changes and AG during goat's prepartum period could be used as diagnostic tool to judge the normality of parturition process, placental dropping, UTI and genital health, in other word, could be used as predictor for goat's fertility prior to parturition.

Barrett's esophagus:Prevalence and risk factors in patients with chronic GERD in Upper Egypt

引用

World Journal of Gastroenterology 2009年第28期15卷 3511-3515页

作者： Yasser m Fouad madiha m makhlouf heba.m.Tawfik Hussein El Amin Wael Abdel Ghany Hisham R El-khayat Department of Tropical medicine and Gastroenterology Minya University Department of Pathology Minya University Department of Internal medicine Gastroenterology Unit Assuit University Department of Gastroenterology Theodore Bilharz Research Institute

AIm： To determine the prevalence and possible risk factors of Barrett＇s esophagus （BE） in patients with chronic gastroesophageal reflux disease （GERD） in EI minya and Assuit, Upper Egypt. mETHODS： One thousand consecutive patients with chronic GERD symptoms were included in the study over 2 years. They were subjected to history taking including a questionnaire for GERD symptoms, clinical examination and upper digestive tract endoscopy. Endoscopic signs suggestive of columnar-lined esophagus （CLE） were defined as mucosal tongues or an upward shift of the squamocolumnar junction. BF was diagnosed by pathological examination when specialized intestinal metaplasia was detected histologically in suspected CLE. pH was monitored in 40 patients. RESULTS： BE was present in 7.3% of patients with chronic GERD symptoms, with a mean age of 48.3 ± 8.2 years, which was significantly higher than patients with GERD without BE （37.4 ± 13.6 years）. Adenocarcinoma was detected in eight cases （0.8%）, six of them in BE patients. There was no significant difference between patients with BE and GERD regarding sex, smoking, alcohol consumption or symptoms of GERD. Patients with BE had significantly longer esophageal acid exposure time in the supine position, measured by pH monitoring. CONCLUSION： The prevalence of BE in patients with GERD who were referred for endoscopy was 7.3%. BE seems to be associated with older age and more in patients with nocturnal gastroesophageal reflux.

Hydrophobic polyethersulfone porous membranes for membrane distillation

Frontiers of Chemical Science and Engineering 2015年第1期9卷 84-93页

作者： heba ABDALLAH Ayman EL-GENDI maaly KHEDR Elham EL-ZANATI Chemical Engineering & Pilot Plant Department Engineering Research Division National Research Center 33 Bohouth st. Dokki Giza Egypt

membrane distillation （mD） is a thermal, vapor-driven transportation process through micro porous hydrophobic membranes that is increasingly being applied to seawater and brine desalination processes. Two types of hydrophobic microporous polyethersulfone fiat sheet membranes, namely, annealed polyethersulfone and a polyethersulfone/tetraethoxysilane （PES/TEOS） blend were prepared by a phase inversion process. The membranes were characterized and their performances were investigated using the vacuum membrane distillation of an aqueous NaCI solution. The performances of the prepared membranes were also compared with two commercially available hydrophobic membranes, polyte- trafluorethylene and polyvinylidene fluoride. The influence of operational parameters such as feed temperature （25-65 ℃）, permeate vacuum pressure （200 800 mbar）, feed flow rate （8-22 mL/s） and feed salt concentration （3000 to 35000 mg/L） on the mD permeation flux were investigated for the four membranes. The hydrophobic PES/TEOS membrane had the highest salt rejection （99.7%） and permeate flux （86 kg/（m^2 -h）） at 65 ℃, with a feed of 7000 ppm and a pressure of 200 mbar.
