NilEDICATIONS are one of the leading causes of fatal and nonfatal poisonings. Of all medications, salicylates (in children) and barbiturates (in adults) are most frequently involved in these poisonings. When these occur, the physician treating the victim may request a chemical analysis of a blood sample to confirm his clinical impression. A salicylate analysis is simple and rapid (1). However, ...

vitex agnus-castus l. is a medicinal plant which is used in several dosage forms for women hormonal disorders and standardized according to the iridoids or flavonoids content. aucubin, an iridoid glycoside, considered as a marker in some formulations. in this research, a thin layer chromatographic method with densitometric detection has been developed for quantitative determination of aucubin i...

Additive manufacturing provides a unique possibility to manufacture parts with advanced design and thin-walled structures. To explore thin-wall capacity, laser powder bed fusion was employed fabricate 316 ​L samples different section thicknesses. A detailed microstructure characterization then carried out, tensile properties were assessed. It found that reducing the part thickness did not affec...

Mechanochemical interactions between myosin and actin-troponin-tropomyosin (regulated thin filaments) underlie muscle contraction. Generally, the binding of a myosin molecule to a regulated thin filament facilitates the binding of nearby myosin; binding is cooperative. A simple yet accurate theoretical description of this cooperativity is lacking. From a general mechanochemical model that treat...

BACKGROUND Cost effectiveness, the ratio of relative costs of a program to its desired outcomes, is one of the basic issues in various screening programs performed to detect opium abuse. This study aimed to find the cost-effectiveness of opiates abuse screening through urine analysis. METHODS A total number of 64698 individuals were selected and divided into to five distinct groups based on t...

In mobile and ubiquitous computing environments, acquisition of contextual information about a user situation is necessary to provide useful services. Although the definition of user context may change according to the situation or the service used, contextual information about who, where, and when are considered to be essential. We have built a test bed with multiple sensors: floor pressure se...
