gum tragacanth is a natural complex mixture of polysaccharides and alkaline minerals extracted from species of astragalus plant, which is found widely in arid regions of the middle east. in a pilot experimental study we examined the effects of its topical application on wound healing in ten albino adult male rats. two similar parasagittal elliptical full-thickness wounds (control vs. test sampl...

STUDY AIMS 2(S)-neopincirin (NEO) is a constituent from of Clinopodium mexicanum, which is used in traditional Mexican herbal medicine for its tranquilizing and analgesic properties. This study investigated the anxiolytic-like, sedative and antinociceptive effects of NEO in several mice models. MATERIAL AND METHODS The anxiolytic-like effect was evaluated in the hole-board (HBT) and Open Fiel...

The conformations of eight neo-confused porphyrin (neo-CP) structures and seven related benzo-neo-confused porphyrins (B-neo-CPs) were minimized using DFT-B3LYP/6-311++G(d,p). In addition, in order to provide contrasts to the B-neo-CP tautomers, a series of twelve benzoporphyrin (BP) tautomers and twelve benzocarbaporphyrins (BCPs) were also analyzed, and two N-confused porphyrin (NCP) tautomer...

We have studied patterns of DNA sequence variation and evolution for 22 genes located on the neo-X and neo-Y chromosomes of Drosophila miranda. As found previously, nucleotide site diversity is greatly reduced on the neo-Y chromosome, with a severely distorted frequency spectrum. There is also an accelerated rate of amino-acid sequence evolution on the neo-Y chromosome. Comparisons of nonsynony...

Causal powers, say, an electron’s power to repel other electrons, are had in virtue of having properties. Electrons repel other electrons because they are negatively charged. One’s views about causal powers are shaped by—and shape—one’s views concerning properties, causation, laws of nature and modality. It is no surprise, then, that views about the nature of causal powers are generally embedde...

Chia-Hao Cheng, Ching-Ho Chang, and Hwei-yu Chang (2011) Early-stage evolution of the neo-Y chromosome in Drosophila albomicans. Zoological Studies 50(3): 338-349. Numerous theories have specified that an originally autosomal neo-Y chromosome arm is expected to undergo degenerative evolution. Neosex chromosomes of Drosophila albomicans originated from 2 Robertsonian translocation events, one fo...
