Starvation Response in Caenorhabditis elegans
… behavioral changes so as to cope with nutrient starvation. Although starvation response is essential for the survival of animals during nutrient deprivation, uncontrolled or uncoordinated starvation responses could be harmful. Autophagy, a lysosomal degradation pathway for long-lived proteins …

Essential Function of Ghrelin in Chronic Starvation
Ghrelin, an octanoylated peptide hormone secreted from the stomach, stimulates the release of growth hormone (GH) from the pituitary. Ghrelin O-acyltransferase (GOAT) is the enzyme required for the attachment of octanoate to serine-3 of ghrelin, a step essential for making active ghrelin. In this …

Survival Strategies of Streptococcus mutans during Carbohydrate Starvation
… It is able to survive long periods of sugar starvation. The purpose of this project was to explore specific avenues that S. mutans may use in order to cope with carbohydrate deprivation. Intracellular polysaccharide (IPS) is accumulated by S. mutans when grown in excess sugar, and can …

Serine Starvation Modulates mRNA Splicing Through Depletion of SR Proteins
… clinical efforts to utilize dietary serine starvation as a potential therapy for serine auxotrophic tumors that cannot make their own serine and are dependent on exogenous serine for growth. This emphasizes the importance of understanding how cancer cells respond to serine starvation. Here, …

Food Habits, Starvation and Growth in the Hellbender, Cryptobranchus Alleganiensis
Cryptobranchus alleganiensis were captured from the Niangua River of Missouri throughout 1974 for a food habits study. Crayfish were the dominant food item, with fish secondary; together, they constituted over 90 percent of stomach content weights in all months. Both fish and crayfish showed …

Phosphate starvation alters calcium signalling in roots of Arabidopsis thaliana
… or whether signalling is altered under P starvation conditions. The aim of this PhD project was to characterise the use of Ca2+ ions, particularly cytosolic free Ca2+ ([Ca2+]cyt), in stress signalling by P-starved roots of the model plant Arabidopsis thaliana. The hypothesis was that under …

Relationship between Semi-Starvation Symptoms, Self-Efficacy, and Weight Loss
The purpose of this study was to explore whether overweight college dieters, engaged in self-structured weight loss efforts, experienced physical symptomatology that has previously been associated with severe caloric restriction. The relationships between physical symptomatology, self-efficacy, and …

On Intelligent Mitigation of Process Starvation In Multilevel Feedback Queue Scheduling
… demand for CPU time exceeds supply and process starvation is inevitable. These schedulers, including Linux CFS, FreeBSD Ule, and the Solaris Fair Share Scheduler, are all effective at favoring interactive processes under starvation conditions.</p> <p>Sometimes it’s not desirable that …

The Unconventional Amino Acid Starvation Response of the Malaria Parasite, Plasmodium falciparum
… how P. falciparum responds to isoleucine starvation, we monitored parasite growth in isoleucine-limiting conditions. We observed that in vitro parasite growth is notably slower in medium containing low concentrations of isoleucine, but completion of the life cycle, consisting of steady …

The Effects of Starvation on The Ruminal Bacteria Megasphaera Elsdenii and Selenomonas Ruminantium
… were subjected to total organic nutrient starvation after growth in batch and/or continuous culture. Both organisms exhibited a very limited survival capacity in comparison to other bacteria reported in the literature. This capacity appears to have been at least partially influenced by …

A new concept and its application for protein sparing therapies during semi-starvation
… fat mobilization and the favorable effects of starvation ketosis during periods of severe negative caloric balance, the efficiency of a limited, carbohydrate free alimentation was tested. Based on a metabolic fuel regulatory system that integrates carbohydrate, amino acid and fat metabolism 0.8 …

The Role of CcpA in Regulating the Carbon-Starvation Response of Clostridium perfringens
… toxins. This work expands the knowledge of the starvation-response of C. perfringens, which includes several potential virulence factors, sporulation, motility and biofilm formation. Sporulation protects cells from a variety of stresses, including starvation. Efficient sporulation requires the …

Survival and recovery of Escherichia coli O157:H7 during starvation at sub-optimal temperatures
… rather than contaminated regulated foods. Starvation and a decrease in temperature are characteristic of the conditions encountered by bacteria during transition from a reservoir host, normally a ruminant, to the environment; cf. feast to famine. These conditions are known to induce …

Ice age wetland biogeochemistry: The influence of carbon dioxide starvation on wetland methane emissions
… Further exploring the effects of CO<sub>2</sub> starvation showed that the fen ecosystem exhibited notable reductions in dissolved organic carbon, dissolved CH<sub>4</sub> and a change in the response of CH<sub>4</sub> flux to changing temperature, variables and relationships which all remained …

Elucidating the mechanisms by which the human pathogen staphylococcus aureus resists host-imposed zinc starvation
… aureus have evolved mechanisms to overcome this starvation. One common mechanism bacteria employ to evade this defense is expression of high-affinity transporters. However, to date, the zinc transporters in S. aureus remain unknown. Expression and growth analysis revealed that S. aureus expresses …

The role of recombinational repair in the mechanism of killing during thymine starvation in Escherichia coli
… phenomenon in which cells cannot recover after starvation for one of the four DNA precursors, dTTP. The mechanism of how cells lose viability during thymine starvation has remained a mystery for decades. In Escherichia coli, thymine-starved cells were observed to accumulate chromosomal breaks …
