Ziziphus spina-christi L. extract from the northern region of Saudi Arabia, was investigated to determine its chemical composition and evaluate antioxidant antifungal properties. Fresh leaves were extracted using Soxhlet apparatus yield 8% w/w. Results qualitative study showed that this is rich in compounds belonging several classes (saponins, phenols, tannins). GC-MS analysis detected 38 with ...

Background and objectivesNatural products from plants their biological potentialities have increased environmental concerns. This study aimed to evaluate the phenolic composition, along with antioxidant, antimicrobial, insecticidal activities of Ziziphus spina-christi leaf extracts using LC-MS.

Studies were performed to determine the significance of temporal variation in vascular smooth muscle Ca(2+) signaling during acute arteriolar myogenic constriction and, in particular, the importance of the stretch-induced intracellular Ca(2+) concentration ([Ca(2+)](i)) transient in attaining a steady-state mechanical response. Rat cremaster arterioles (diameter approximately 100 microm) were d...

Tungsten carbide cobalt hardmetals are commonly used as cutting tools subject to high operation temperature and pressures, where the mechanical performance of tungsten phase affects wear lifetime material. In this study, behaviour isolated (WC) was investigated using single crystal micropillar compression. Micropillars in two orientations, 1-5 ${\mu}$m diameter, were fabricated focused ion beam...

OBJECTIVE We reviewed our series of olfactory groove meningiomas (OGMs) with the aim to relate the surgical approach with outcome and to define clinical and pathologic predictors of prognosis. METHODS Ninety-nine patients who underwent 113 craniotomies at our Institution between 1984 and 2010 were entered this study. The relationship between surgical approach (bifrontal, fronto-orbito-basal, ...
