Following injury, stem cells restore normal tissue architecture by producing the proper number and proportions of differentiated cells. Current models of airway epithelial regeneration propose that distinct cytokeratin 8-expressing progenitor cells, arising from p63(+) basal stem cells, subsequently differentiate into secretory and ciliated cell lineages. We now show that immediately following ...

Macrophomina phaseolina and Sclerotinia sclerotiorum are two significant fungal pathogens of sunflower. M. causes charcoal rot ashy stem blight in several important crop species. white mold disease which can occur as middle stalk rot, head premature plant death. Due to the wide host range their survival structures, rotation cannot provide sufficient protection against them. In our experiment, w...

BACKGROUND/AIMS In the present study, we explored reactive axygen species (ROS) production in mitochondria, the mechanism of hexavalent chromium (Cr(VI)) hepatotoxicity, and the role of protection by GSH. METHODS Intact mitochondria were isolated from rat liver tissues and mitochondrial basal respiratory rates of NADH and FADH2 respiratory chains were determined. Mitochondria were treated wit...

The objective of this study was to determine the effect of different levels of chicory root and stem powder (CRSP) and butyric acid (BA) combination on the performance, carcass traits, relative weight of internal organs and some blood parameters in broiler chickens. Two hundred and forty one-day-old broilers (Ross 308) were used in a completely randomized design with four treatments with six re...

587 Abstract: The severity of brown stem rot (BSR) on soybean (Glycine max) is influenced by environment, genotype of the pathogen, and genetic resistance to BSR. BSR is caused by two genotypes of Phialophora gregata: genotype A causes pith browning and leaf necrosis, and genotype B typically causes only pith browning. The distribution of the genotypes and their interactions with resistant and ...
