The chemical and enzymatic properties of the cytochrome system in the particulate preparations obtained from dormant spores, germinated spores, young vegetative cells, and vegetative cells of Bacillus subtilis PCI219 were investigated. Difference spectra of particulate fractions from dormant spores of this strain suggested the presence of cytochromes a, a(3), b, c(+c(1)), and o. All of the cyto...

In the United States, many state and federally funded conservation programs are required to quantify the water quality benefits resulting from their efforts. The objective of this research was to evaluate the impact of conservation practices subsidized by the Oklahoma Conservation Commission on phosphorus and sediment loads to Lake Wister. Conservation practices designed to increase vegetative ...

Initial conceptualisation about the nature of vegetative state (VS) assumed at least temporary loss of the entire cortical functioning. Since a broad range of stimulus-related cortical activations was demonstrated in VS patients, this simplified idea is not tenable any longer, but no alternative concept emerges instead. Two recent hypotheses, empirically testable and well grounded, could fill t...

In S. pombe, about 5% of genes are meiosis-specific and accumulate little or no mRNA during vegetative growth. Here we use Affymetrix tiling arrays to characterize transcripts in vegetative and meiotic cells. In vegetative cells, many meiotic genes, especially those induced in mid-meiosis, have abundant antisense transcripts. Disruption of the antisense transcription of three of these mid-meiot...

background: the predominant phytoestrogen in soy and derived products is the isoflavone genistein. genistein has antioxidant properties. morphine is a main psychoactive chemical in opium that can increase the generation of free radicals and therefore it could adversely affects the spermatogenesis. objective: the main goal was to investigate whether the genistein could protect morphine adverse e...

introduction: anethole is the main constituent of pimpinella anisum l. (anise), a herbaceous annual plant which has several therapeutic effects. in the folk medicine, anise is employed as an antiepileptic drug. specifically, this study was focused on the cellular effect of anethole, an aromatic compound in essential oils from anise and camphor. anethole has various physiological effects on the ...
