The ability to adapt to adverse environmental conditions encountered in food and during host infection is a sine qua non for a successful Listeria monocytogenes infection. This ability is likely to depend on complex regulatory pathways controlled by a number of key regulators. We utilized the pORI19 plasmid integration system to analyze the role of six putative regulatory loci in growth under s...

During past several years, there has been growing interest among the usage of various medicinal plants from traditional system of medicine for the treatment of different ailments. A number of herbs belonging to the specie Abutilon are noted for their medicinal benefits in traditional system of medicine. A lot of medicinally important attributes have been assigned to the plants of this specie. T...

Introduction: Flemingia faginea, a Fabaceae family medicinal plant, has been used for long time in Burkina Faso the treatment of hypertension and excess salt. However, safety preparations derived from this plant not yet scientifically documented. This study aimed to evaluate acute subacute oral toxicity leafy stems aqueous decoction F. faginea (FAD) healthy normotensive mice rats impact on thei...

We examined the effects of nitric oxide (NO) and sodium nitroprusside (SNP) on Bacillus subtilis physiology and gene expression. In aerobically growing cultures, cell death was most pronounced when NO gas was added incrementally rather than as a single bolus, suggesting that the length of exposure was important in determining cell survival. DNA microarrays, Northern hybridizations, and RNA slot...

The leaf mosaic of Abutilon sellovianum is caused by abutilon mosaic virus (AbMV), a geminivirus that has a circular single-stranded DNA genome. DNA was isolated from intact plastids of AbMV-infected and noninfected plants. Plastids from infected plants were shown to contain the single-stranded AbMV DNA by Southern-blot hybridization experiments that used a probe made from highly purified AbMV ...

Aim of this paper is to find out the relationship between antioxidant activity of Abutilon indicum Linn and their phytochemical composition especially phenols and flavonols. Successive extractions were carried out for the Abutilon indicum plant with petroleum ether, chloroform, ethyl acetate, n-butanol, ethanol and water. All these extracts were evaluated for their antioxidant activities. Their...

BACKGROUND Epidemiological and experimental evidences have shown cancer as a leading cause of death worldwide. Although the folklore use of plants as a reliable source of health-restoring principles is well-documented, the search for more of such plants that are active against diseases, such as cancer, continues. We report here a laboratory-based evidence of the relevance of an ethanol leaf ext...
