Diabetic mellitus is a group of metabolic disorders in which there are high blood sugar levels over a prolonged period, diabetes can causes many complications. The trace element vanadium has unclear biological functions. Vanadate, an oxidized form of vanadium, appears to have an insulinlike action, the effect of vanadate on blood glucose was assessed in male Wistar rats after they were made diabetic with Streptozotocin (STZ). The animals were fasted overnight and a single intraperitoneal injection of a freshly prepared solution of STZ (55 mg/Kg b.wt) in 0.1 M cold citrate buffer (PH 4.5) was given to induce diabetes. The animals were allowed to access to 5 per cent glucose solution overnight, to prevent total hypoglycemia, induced by STZ by massive pancreatic insulin release. The animals were considered as diabetic, if their blood glucose values were above 250 mg/dL on the third day (72 hours) after STZ injection. The treatment was started on the fourth day after STZ injection and the day was considered as first day of treatment. The treatment was continued for 15 days. Diabetes causes disturbance in liver and kidney functions and causes hyperlipidemia also decreased the antioxidant activity; after the treatment with the two novel vanadium complexes , all functions of liver (Alanine transferase, Aspartate transferase and total protein) and kidney functions ( Creatinine and urea ) were improved. Also, lipid profile (total cholesterol and Triglycerides) level decreased and the activity of antioxidant enzymes (Superoxidedismutase, Glutathione peroxidase, Glutathione reductase and Malonodialdhyde)

In this study, ion pairs formed between tetrabutyl ammonium bromide as surfactant and ion pairing agents as phosphotungetic acid (PTA), phosphomolybdic acid (PMA) and sodium tetraphenyl borate (NaTPB) have been used as electroactive materials for preparation of modified carbon paste electrodes (CPEs) selective to tetra-n-butyl ammonium bromide (TBAB) surfactant. Type and content of the different ion pairs on the performance of CPEs were studied. It was found that the best contents were, 15 mg of TBA-TPB (electrode I), 15 mg TBA-PTA (electrode II) and 6 mg TBA-PMA (electrode III) ion pairs, which gave the best Nernstian slope values of 59.41±0.31, 59.26±0.45 and 59.95±0.35 mVdecade, respectively. These fabricated electrodes exhibited suitable response to TBAB in a concentration range from 1.0x10 to 1.0x10 mol L with lower detection limit of 1.0x10 mol L. These fabricated electrodes exhibited fast response time of about 3, 7 and 6 s under working pH range of 3-8, 5-8 and 5-9 for electrodes I, II and III, respectively. The results obtained were satisfactory with excellent percentage recovery comparable and sometimes better than those obtained by other routine methods for the assay of TBAB surfactant.

The evaluation of gas reservoirs in Alam El Bueib has been dealt with through the interpretation of well log data. Alam El – Bueib (AEB) formation is monitored in Matruh basin at the Northern part of the Western Desert, Egypt encountered many gas producing reservoirs. Alam ElBueib – 3G (AEB – 3G) member was chosen for application of the presented techniques. The available well log data are in the form of Gamma Ray, Bit size, Caliper, Resistivity, Neutron, Density, Sonic and Photoelectric. The reservoir petrophysical parameters (Фeff, Sw, Bvw) besides mineralogical make up were evaluated for this member in JADE – 8 well. The gas zone represents a challenge for well log interpretation technique as they normally plotted above the standard porosity lines. A graphical technique was used to get Фeff in the zones on the ρb – ФN cross plot. The Sw Vs Ф was presented graphically on log – log plot for obtaining BVW constant lines. Line with slope unity discriminates between reservoir and non-reservoir for AEB – 3G member.

The present study aimed to evaluate the protective and therapeutic effects of M. oleifera leaves against toxicity induced by PbCl2 in albino male rats. Thirty-six albino rats weighing about 182.8 g were divided into 6 groups each of 6 rats. Control group, left without treatment. The PbCl 2 group treated orally with 200 mg PbCl 2 daily for 30 days. The M. oleifera group treated orally with 200 mg M. oleifera daily for 30 days. PbCl 2 + M. oleifera group (200 mg PbCl 2 + 200 mg M. oleifera ). Therapeutic group (200 mg PbCl 2 followed by 200 mg M. oleifera ) and protective group (200 mg M. oleifera followed by 200 mg PbCl 2 ). At the end of the experiment, both kidney and liver function tests were assayed as well as catalase and SOD enzymes activity and MDA level. The activity of ALT and the levels of bilirubin, urea, creatinine, cholesterol, ammonia, urea and triglycerides were elevated after lead administration compared with the control and protective groups (p<0.05) but the level of albumin of the same group was decreased compared with the control group. In protective group, the level of MDA was significantly decrease compared with that of the lead group. On the other hand, the activities of SOD and catalase were significantly increase in the protective group as well as other treated groups compared with the control group (p<0.05). In conclusion, treatment with M. oleifera leaves can protect liver and kidney against lead toxicity.

The aim of this work to investigate the effects of sodium fluoride (NaF) on male reproductive function and evaluate the protective effects of inulin against sodium fluoride (NaF) induced male reproductive toxicity in adult male albino rats. In this study, forty adult male albino rats were used, they were divided randomly into four groups: a control group (1), which was given distilled water, and three treatment groups, which was received daily oral doses of; sodium fluoride (10 mg/kg.b.w.) of group (2), inulin (10 mg/kg) + sodium fluoride (10 mg/kg) of group (3), and inulin (10 mg/kg.b.w.) of group (4) for 3 months. The sperm quality, complete sperm motility, morphology and sperm count were assessed. The levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), testosterone (T), and progesterone (P) were used as indicators of male reproductive health. The whole testis tissues isolated was used for histopathological studies. The results showed that sodium fluoride induces severe toxic changes in the male reproductive system and inulin could provide these toxic effects.

This study was concerned with the isolation of bacterial strains from different water sources. Among these strains; Enterobacter sp. exhibited extracellularly biosynthesized silver nanoparticles with good monodispersity. Enterobacter sp. has produced extremely stable nanoparticles within 72 hrs at 35°C in dark conditions. These nanoparticles are characterized by UV–vis spectrophotometer, transmission electron microscopy, Zeta potential analyzer, and size distribution by volume. Enterobacter sp. synthesized 9.45-17.15 nm sized spherical shaped silver nanoparticles. The presence and binding of stabilized proteins with nanoparticles were confirmed by the zeta size distribution by volume. Our study demonstrates that silver nanoparticles are potent inhibitors of the plant pathogenic fungus, Fusarium oxysporum f. sp. lycopersici.

The seismic attributes help the interpreter to extract more information from conventional seismic data to support the geologic interpretations for the examined study area. The present work has revealed that the best seismic attributes which can be used to display the buried channels include, envelope, RMS amplitude, sweetness, chaos and spectral decomposition attributes. However, structural dip and variance attributes enhance the appearance of faults and fractures on the seismic sections. .

A field experiment was carried out to evaluate the responses of six oil sunflower ( Helianthus annuus L) genotypes namely; Sakha 53, H(A9XRf6), B11, B12, H(A9XRf8) and B20 to drought stress. Plants were subjected to three levels of water: adequate (control), moderate drought and severe drought Water regime was started directly post anthesis by withholding water during seed-filling stage until complete maturity of seeds. Moderate and severe drought decreased plant height and stem diameter of all genotypes, except B11 and B20 which recorded non-significant decrease in plant height under moderate drought. On the other hand, non-significant effect was observed in leaf area in all genotypes except B12 and H(A9XRf8) where a significant decrease was recorded only under severe drought. Yield components (head diameter, seed yield, 100 seed weight, seed husk %, seed kernel % , and oil percentage) responded to drought stress differently according to genotypes. Significant decreases were observed in floral head diameter seed yield, oil percentage and protein content in all genotypes except for the non-significant reduction in seed yield and oil content in Sakha53 and H(A9XRf6) under moderate drought Generally, Skha53 was the most drought-tolerant genotype whereas B11, B12 and B20 exhibited the least tolerance.

Plants were subjected to three levels of water: adequate (control), moderate drought and severe drought Water regime was started directly post anthesis by withholding water during seed-filling stage until complete maturity of seeds. Moderate and severe drought decreased plant height and stem diameter of all genotypes, except B11 and B20 which recorded non-significant decrease in plant height under moderate drought. On the other hand, non-significant effect was observed in leaf area in all genotypes except B12 and H(A9XRf8) where a significant decrease was recorded only under severe drought. Yield components (head diameter, seed yield, 100 seed weight, seed husk %, seed kernel % , and oil percentage) responded to drought stress differently according to genotypes. Significant decreases were observed in floral head diameter seed yield, oil percentage and protein content in all genotypes except for the non-significant reduction in seed yield and oil content in Sakha53 and H(A9XRf6) under moderate drought Generally, Skha53 was the most drought-tolerant genotype whereas B11, B12 and B20 exhibited the least tolerance.","PeriodicalId":21655,"journal":{"name":"Scientific Journal for Damietta Faculty of Science","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75486287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over two-year period starting June 2014, 72 water samples were collected from Omar Bek drain, Damietta branch upstream and downstream. Based on physical, chemical and bacteriological results obtained, The physical analysis was temperature, pH, and turbidity, chemical analysis was total dissolved salts (TDS), electrical conductivity(EC), alkalinity, total hardness, manganese, iron, nitrite (NO2), nitrate (NO3), ammonia (NH3), dissolved oxygen (DO), and bacteriological analyses involved total coliforms (TC), fecal coliforms (FC), and Fecal Streptococci (FS). Results showed Omar Bek drain water carries high concentrations of pollutants which affected on all parameter of Nile River downstream. Also, the present investigation showed that Damietta branch upstream was a good raw water quality while Damietta branch downstream was affected by presence of Omer Bek drain.
