this work is aimed to evaluate the role of nanoclay in the protective performance of an eco-friendly silane sol-gel layer applied on mild steel substrate in 0.1m sodium chloride solution. at the first step, the effect of ph of the silane solution, consisting of a mixture of γ-glycidoxypropiltrimethoxysilane and methyltriethoxysilane and tetraethoxysilane, on the coating performance was evaluate...

Research on street-based female sex workers documents a multitude of problems faced by these women, such as substance use, HIV risk, mental health problems, victimization, and homelessness. The presence of problems such as these is understood as a syndemic, or co-occurrence of two or more risk factors that act synergistically to create an excess burden of disease.

BACKGROUND Leishmaniasis remains a significant cause of morbidity and mortality in the tropics. Available therapies are problematic due to toxicity, treatment duration and emerging drug resistance. Mouse models of leishmaniasis have demonstrated that disease outcome depends critically on the balance between effector and regulatory CD4(+) T cell responses, something mirrored in descriptive studi...

Understanding differences in responses following attempts to suppress versus simply monitor intrusive thoughts is important given the established relationship between intrusive thinking and numerous forms of psychopathology. Moreover, these differences may vary as a function of age. Because of the links between aging and both enhancement in emotion regulation skills and decline in inhibition sk...

The present study investigates the effects of two extracts from <i>Cynomorium songaricum</i> (CS) on skin barrier enhancement and astringent activity. Although CS have been reported in various diseases including cancer, diabetes inflammatory diseases, protective are poorly understood. To test protection abilities, anti-oxidant anti-inflammatory activities radical scavenging activity...
