The responses of Pseudomonas putida KT2442 to various forms of nutrient starvation and stress conditions were examined by two-dimensional polyacrylamide electrophoresis. Carbon deprivation resulted in a temporal expression of two classes of starvation-induced proteins: one class was transiently expressed during the initial phase of starvation, and the second class was expressed throughout the e...

Many biological species increase their dispersal rate if starvation starts. To model such a behavior, we need to understand how organisms measure starvation and response to it. In this paper, we compare three different ways of measuring starvation by applying them to starvation-driven diffusion. The evolutional selection and coexistence of such starvation measures are studied within the context...

The isoleucine and valine biosynthetic enzyme acetolactate synthase (Ilv2p) is an attractive antifungal drug target, since the isoleucine and valine biosynthetic pathway is not present in mammals, Saccharomyces cerevisiae ilv2Delta mutants do not survive in vivo, Cryptococcus neoformans ilv2 mutants are avirulent, and both S. cerevisiae and Cr. neoformans ilv2 mutants die upon isoleucine and va...

AIMS The cytokine macrophage migration inhibitory factor (MIF) protects the heart through AMPK activation. Autophagy, a conserved pathway for bulk degradation of intracellular proteins and organelles, helps preserve and recycle energy and nutrients for cells to survive under starvation. This study was designed to examine the role of MIF in cardiac homeostasis and autophagy regulation following ...

This paper presents an experimentally validated numerical approach linear roller guideways considering coupled vertical and horizontal (feed) motions taking into account lubricant starvation. The inlet starvation is considered by incorporating potential flow method. Results show that has pronounced effect on the film thickness, friction, applied load contact up to 32%. Localised pressure values...

Anthropogenic and extreme climate disasters cause ecological changes in natural rivers lakes, increasing the risk of starvation yellowcheek (Elopichthys bambusa). Therefore, impact on metabolism wild population should be explored. In this study, we used transcriptome sequencing technology to analyze effects short (8 d) long-term (28 liver transcriptome, growth, serum indicators yellowcheek. Our...

Shared psychotic disorder also known as folie a dues is thought to occur in persons who live close together, so that delusions of the primarily ill patient are transferred to the partner. A case of shared paranoid psychotic disorder, with primary diagnosis of persecutory delusional disorder in the husband is described. The delusion and its consequent safety behaviors were so strong that led to ...

Levels of RpoS increase upon glucose starvation in Escherichia coli, which leads to the transcription of genes whose products combat a variety of stresses. RpoS stability is a key level of control in this process, as SprE (RssB)-mediated degradation is inhibited under glucose starvation. Starvation for ammonia or phosphate also results in increased stress resistance and induction of RpoS-depend...

Anaerobic starvation conditions are frequent in industrial fermentation and can affect the performance of the cells. In this study, the anaerobic carbon or nitrogen starvation response of Saccharomyces cerevisiae was investigated for cells grown in anaerobic carbon or nitrogen-limited chemostat cultures at a dilution rate of 0.1 h(-1) at pH 3.25 or 5. Lactic or benzoic acid was present in the g...
