Biomolecular motors have inspired the design and construction of artificial nanoscale motors and machines based on nucleic acids, small molecules, and inorganic nanostructures. However, the high degree of sophistication and efficiency of biomolecular motors, as well as their specific biological function, derives from the complexity afforded by protein building blocks. Here, we discuss a novel b...

The study was planned to determine the chemical composition and antimicrobial properties of essential oil Verbena rigida Spreng. cultivated in Egypt. from aerial parts prepared by hydrodistillation a yield 0.26 % v/w. has been elucidated gas chromatography-mass spectroscopy analysis. tested against selected species Gram-positive, Gram-negative bacteria Candida using disc diffusion method MICs w...

A new lignan glycoside, named juniperigiside (1) was isolated from the CHCl(3) soluble fraction of the MeOH extract of stems and leaves of Juniperus rigida S.et Z. Compound 1 was identified by 1D- and 2D-NMR spectroscopy as well as CD analysis as (2R,3S)-2,3-dihydro-7-methoxy-2-(4'-hydroxy-3'-methoxyphenyl)-3-hydroxymethyl-5-benzofuranpropanol 4'-O-(3-O-methyl)-α-L-rhamnopyranoside. Five known ...

Genus Salsola, a genus of annual semi-dwarf to dwarf shrubs and woody tree species, is widely distributed across the arid and semi-arid areas of the world. Several features like high fodder value, abundant seed production, tolerance to extreme climatic conditions like high temperature and prolonged drought conditions contributed significantly towards its success as a potential forage species in...
