Microbes have evolved ways of interference competition to gain advantage over their ecological competitors. The use of secreted antagonistic compounds by yeast cells is one of the prominent examples. Although this killer behavior has been thoroughly studied in laboratory yeast strains, our knowledge of the antagonistic specificity of killer effects in nature remains limited. In this study, yeas...
conclusions these human-derived lab and bifidobacteria exhibited different mechanisms involved in pathogenic inhibition. therefore a combination of these probiotic strains could be a great promise and possibility for the development of probiotic products to effectively prevent and control food-borne infection in humans. background food-borne pathogens are among the most significant problems in ...
background and objectives: to find antagonistic bacteria with potential antifungal activity against some pathogenic fungi, including aspergillus niger , a. flavus, fusarium moniliforme and penicillium marneffei , a total of 148 agricultural soil samples from different sites of tehran were examined. materials and methods: antagonistic soils were selected by screening against a. niger on glucose...
The prospective of endophytic microorganisms allied with medicinal plants is disproportionally large compared to those in other biomes. The use of antagonistic microorganisms to control devastating fungal pathogens is an attractive and eco-friendly substitute for chemical pesticides. Many species of actinomycetes, especially the genus Streptomyces, are well known as biocontrol agents. We invest...
The caffeine-induced impairment of insulin action is commonly attributed to adenosine receptor (AR) antagonism in skeletal muscle. However, epinephrine, a potent inhibitor of insulin actions, is increased after caffeine ingestion. We tested the hypothesis that the insulin antagonistic effects of caffeine are mediated by epinephrine, and not by AR antagonism, in seven healthy men. On four separa...
Adverse environmental conditions trigger C. elegans larvae to activate an alternative developmental program, termed dauer diapause, which renders them stress resistant. High-level insulin signaling prevents constitutive dauer formation. However, it is not fully understood how animals assess conditions to choose the optimal developmental program. Here, we show that insulin-like peptide (ILP)-med...

The purpose of the present work was to investigate the mechanism underlying the inhibitory action of rebamipide on superoxide anion (O2) production induced by the chemotactic peptide formyl-methionyl-leucyl-phenylalanine (fMLP) in human neutrophils. Phosphatidylinositol 3,4,5-trisphosphate (PIP(3)), a product of phosphoinositide 3-OH-kinase (PI 3-kinase) accumulated in response to fMLP and this...
