In this article 5-25 V% of a sol-gel bioglass fiber was incorporated into calcium phosphate bone cement to improve its mechanical properties. Compressive strength, work of fracture, elastic modulus and setting time of the cement were investigated as well as phase changes occurring during soaking the specimens in simulated body fluid (SBF). The cement microstructure was also observed by scanning...

M any of tho probl,n~ of o'gall tran,plantation could be minimized if it were possible to mitigate graft rejection by modifying the transplanted tissue rather than the host immunologic response. Efforts to achieve this objective have been unsuccessful, with occasional possible exceptions,4, 9, 11 of which the most intriguing was described by Jolley, Hinshaw, and PetersonY They reported that rab...

X-ray crystallography is an important technique for structure-based drug discovery, mainly because it is the only technique that can reveal whether a ligand binds to the target protein as well as where and how it binds. However, ligand screening by X-ray crystallography involves a crystal-soaking experiment, which is usually performed manually. Thus, the throughput is not satisfactory for scree...

The purpose of this in vitro study was to evaluate the burnishing effect of saline application on dentin specimens (NaCl 0.9%). Seventy-two dentin specimens (60 experimental and 12 controls) were equally divided into two groups. In Group A; sub-groups I, II, III, IV and V were respectively soaked with saline for 5 s, 10 s, 30 s, 1 min and 2 min. Group VI was soaked in citric acid for 3 min and ...

Five biotic and abiotic inducers namely, (Bio-Arc and Bio-Zaid) and (salicylic acid, K HPO and neem 2 4 oil) were examined for their effectiveness in controlling fungal diseases, improving growth and yield of alfalfa. The field trials have shown that salicylic acid, K HPO and neem oil respectively gave a significant P 0.05 2 4 protection against rust, downy mildew in both tested cvs. Ismailia-1...

The changes in lipid and fatty acid contents after soaking, cooking, germination and fermentation of three white sorghum varieties were studied to improve cereal quality. The results revealed that oil in raw sorghum varieties ranged from 3.58 to 3.91%, respectively and ‘Dorado’ represents the highest variety in oil content. As general trend after germination, oil content was decreased. Fatty ac...

Compression molded composites were made from wood particles and a liquefied wood/phenol/formaldehyde co-condensed resin. Based on our previous research, a phenol to wood (P1W) ratio of 2/1 was chosen for this study. The two experimental variables selected were: 1) liquefaction temperature (1500 and 180°C) and 2) cooking method (atmospheric and sealed). Panels were tested in static bending for m...

The present investigation was conducted to study the effect of processing (soaking and germination) and cooking methods (ordinary cooking and autoclaving) on the chemical composition, sugars and phytic of two varieties soybean seeds, Giza, 21 and Giza, 35. The processing and cooking methods caused increase in both protein and crude fiber contents. Meanwhile, crude oil and carbohydrates contents...

It has been recommended by the World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC) that rigorous decontamination protocols be used on surgical instruments that have been exposed to tissue possibly contaminated with Creutzfeldt-Jakob disease (CJD). This study was designed to examine the effects of these protocols on various types of surgical instruments. The most...
