The response of the estuarine human pathogen Vibrio vulnificus to starvation for carbon, nitrogen or phosphorus, or all three nutrients simultaneously (multiple-nutrient), was examined with respect to the maintenance of culturability during incubation at low temperature. V. vulnificus showed similar survival patterns during starvation for the individual nutrients when kept at 24 degrees C. On t...

the effect of starvation and re-feeding was investigated on growth, hematology and biochemical parameters in juvenile persian sturgeon (acipenser persicus). three hundred and seventyfive fish (108±0.63 g) were divided into five feeding groups. the control group (c) was fed to satiation three times a day during the experiment. the four groups were starved for 1 (w1), 2 (w2), 3 (w3), and 4 (w4) w...

electron transport system (ets) activity was found to be related to the initial inoculum size,culturability and viability of e. coli. in this experiment, ets activity of flexibacter chinensis was measuredby int-method under a variety of conditions such as starvation media with different amendments anddifferent temperatures. the relation between ets activity, cell culturability, and viability wa...

Signaling trough p53 is a major cellular stress response mechanism and increases upon nutrient stresses such as starvation. Here, we show in human hepatoma cell line that starvation leads to robust nuclear stabilization. Using BioID, determine the cytoplasmic interaction network within immediate-early dissociated from several metabolic enzymes kinase PAK2 for which direct binding with DNA-bindi...

Intestinal epithelial cells are tightly bound by tight junction proteins (TJP) which dynamic and sensitive to environmental stress. However, the role of endocytic pathway in regulation TJP abundance integrity during nutrient stress is poorly understood. Therefore, this study was conducted investigate starvation mechanism process. IPEC-J2 were subjected Krebs-Ringer bicarbonate buffer (KRB) TJP,...

Eukaryotes harbour a conserved signalling pathway, called General Amino Acid Control (GAAC) in Saccharomyces cerevisiae, for overcoming amino acid starvation. Upon starvation, the protein kinase Gcn2, which phosphorylates eukaryotic translation initiation factor eIF2α, becomes stimulated to trigger GAAC response. Genetic studies suggest that Yih1, is yeast homolog of mammalian IMPACT and binds ...

Starvation induces sustained increase in locomotion, which facilitates food localization and acquisition and hence composes an important aspect of food-seeking behavior. We investigated how nutritional states modulated starvation-induced hyperactivity in adult Drosophila. The receptor of the adipokinetic hormone (AKHR), the insect analog of glucagon, was required for starvation-induced hyperact...

This study aimed at determining blood biochemical parameters with potential diagnostic value to assess the nutritional status for healthy Snow trout, Schizothorax zarudnyi. For this purpose, three treatment groups of Snow trout (average weight, 65.9±5.3 g) were kept unfed for 24 h, 7 and 14 days. During the experiment, a natural photoperiod was adopted, water temperature was maintained at 23.2±...
