Nigella sativa and Matricaria chamomilla are extensively consumed as tea or tonic. Despite their widespread use as a home remedy, relatively few trials evaluated their benefits in nephroprotection. Hence, this study evaluates the nephroprotective effects of supportive treatments (N. sativa, M. chamomilla and vitamin E) in cisplatin nephrotoxicity rat model. Eighty rats divided into 10 groups, of 8 animals each. The first group (G1) injected with saline intra-pretoneal (i.p). G2 injected with 5 mg/kg cisplatin i.p on zero day of experiment and repeated 4 times, with 5 days free interval. G3-G10 received daily supportive treatments, started 5 days before the experiment (–5day). Concomitantly G4, G6, G8 and G10 injected with 5 mg/kg cisplatin i.p like G2. On day sixteen, animal scarified, serum and/or kidney tissue were used to determine kidney function tests (serum urea, creatinine, NAG, β-gal), oxidative stress indices (NO, LPO), antioxidant activities (SOD), sulphur compounds (GGT, GSH, total thiols ), apoptotic indices (cathepsin D, DNA fragmentation), two minerals (Ca2+ and zn2+). Cisplatin caused marked elevation in serum GGT that reduced signifi-cantly in group received M. chamomilla with cisplatin (P elation between GGT and NAG in cisplatin group (r = 0.731 p ely.

Yield and Quality Response of Ryegrass, Egyptian Clover and Their Mixtures to Different Sources of Fertilizers

引用

Agricultural Sciences 2015年第1期6卷 137-145页

作者： Alice Tawfik Thalooth Gaber abd-Latif sary Haroon Mohamed el-Nagar Mohamed Farouk el-Kramany Mohamed Omer Kabesh Gehan Shaker Hanna Bakhoum Field Crops Research Department National Research Centre Giza Egypt Agronomy Department Faculty of Agriculture Benha University Benha Egypt

Two field experiments were conducted during two successive winter seasons of 2008/2009 and 2009/2010 to investigate the potentialities of mixing Egyptian clover with ryegrass under bio, organic and mineral fertilization treatments and their combination to increase forage yield and quality grown under sandy soil conditions. The experiment included the combination of five mixing ratios (Egyptian clover alone, ryegrass alone, 75% Egyptian clover: 25% ryegrass, 50% Egyptian clover: 50% ryegrass and 25% Egyptian clover: 75% ryegrass) and eight fertilizer sources, which include control, organic fertilization, bio fertilization, chemical fertilizer, organic + bio fertilizer, organic + chemical fertilizer, bio + chemical fertilizer and combination of organic and chemical and bio fertilizers. The obtained results indicate the superiority of 75% E. clover: 25% ryegrass mixture fertilizedby Bio + O + N in fresh and dry forage production. On the other hand, it reported the lowest dry weight of weeds g/m2. Chemical analysis of forage plants showed that the mixture of ?75% E. clover: 25% ryegrass surpassed that of other treatments yield for crude protein, ether extract and ash. The results also revealed that the highest record of DCP, crude fiber and TDNY was obtained by forage mixture of 75% E. clover: 25% ryegrass fertilized with Bio + O + N. Such higher yield of these characters hassecured a balanced ratio which is really needed for ruminants ration.

Effect of restoration technique on resistance to fracture of endodontically treated anterior teeth with flared root canals

The Journal of Biomedical Research 2019年第2期33卷 131-138页

作者： sary S Borzangy Samah M Saker Walid A Al-Zordk Department of Substitutive Dental Sciences College of Dentistry Taibah University Department of Fixed Prosthodontics Faculty of Dentistry Mansoura University

This study was designed to compare the impact of post and core systems on resistance to fracture of endodontically treated anterior teeth with flared root canals and to assess their fracture pattern. Sixty central incisors were cut horizontally 2 mm coronal to the cementoenamel junction(CEJ). After root canal therapy, teeth were assigned into 6 groups(n = 10 each) based on a post system and used as follows: Group C, non-flared root received size #1 glass fiber posts(Control); Group AP, flared root restored with anatomical post; Group RC, flared root restored with size #1 fiber post and cemented with thick layer of resin cement; Group CR, flared root restored with size #1 and reinforced with composite resin; Group CM, cast post-core; Group CP, CAD/CAM polymer-infiltrated ceramic post and *** post cementation, core build-up and crown insertion, the specimens were thermo-cycled up to 10,000 cycles(5 C/55 C; 30 seconds dwell time, 6 seconds transition time) and then statically loaded at 1 mm/minute crosshead speed using a universal testing machine. One-way ANOVA and Tukey HSD post hoc test(α= 0.05) were used for data analysis. Group C recorded significantly higher resistance to fracture values [(826.9±39.1) N] followed by group CP [(793.8±55.6) N] while group RC yielded the lowest fracture resistance values [(586.7±51.4) N]. The resistance to fracture of wide root canals can be enhanced by using one-piece CAM/CAM post and core as an alternative to the use of either glass fiber post, relined with composite resin increasing the thickness of luting cement or the use of cast post and core system. However, this was an in vitro investigation and further in vivo studies are necessary.

3-D multidetector computed tomography in reoperative cardiac surgery

引用

World Journal of Cardiovascular Diseases 2013年第5期3卷 389-393页

作者： Tsuyoshi Kaneko Micheal L. Steigner Igor Gosev sary F. Aranki Department of Cardiac Surgery Brigham and Women’s Hospital Boston USA Department of Radiology Brigham and Women’s Hospital Boston USA

Reoperative cardiac surgery is becoming more common surgery although it carries significant risk due to possible injury to vital structures under the sternum. Three-dimensional multidetector computed tomographic angiography (3-D MDCTA) allows identifying the relationship between the sternum and the mediastinal structures. Evidence shows that 3-D MDCTA guides surgical strategy and enables to perform this challenging surgery safely.
