Antibacterial and antioxidant properties of the leaves and stem essential oils (EOs) of Jatropha gossypifolia and their efficacies against infectious and oxidative stress diseases were studied in vitro. The EOs obtained using Clevenger modified apparatus were characterized by high resolution GC-MS, while their antioxidant and antibacterial properties were examined by spectrophotometric and agar...

Hollow CdS nanoboxes, having paper-thin walls of well-defined facets, were synthesized at 170 degrees C via a simple reaction using Na(2)SeO(3) for interior quasitemplates and ethylenediamine for exterior molecular templates.

Composite-order bilinear groups provide many structural features that are useful for both constructing cryptographic primitives and enabling security reductions. Despite these convenient features, however, composite-order bilinear groups are less desirable than prime-order bilinear groups for reasons of both efficiency and security. A recent line of work has therefore focused on translating the...

Selenophosphate is the active selenium-donor compound required by bacteria and mammals for the specific synthesis of Secys-tRNA, the precursor of selenocysteine in selenoenzymes. Although free selenide can be used in vitro for the synthesis of selenophosphate, the actual physiological selenium substrate has not been identified. Rhodanese (EC ) normally occurs as a persulfide of a critical cyste...
