In this study, the effect of short-terms starvation (0, 2, 4 and 8 days) on plasma cortisol, glucose, triglyceride and cholesterol levels and also hepatosomatic index in Siberian sturgeon, Acipenser baerii, was investigated. After acclimation to experimental conditions for 10 days using formulated diet, 180 juvenile Siberian sturgeons (mean weight ? S.E.=19.3?0.4, n=15) were randomly distribute...

In this thesis, starvation is defined as the phenomena where a flow receives throughput persistently and severely lower than its reference rate. Throughout the thesis, I investigate the cause of starvation, explore its solution space, and present mechanisms to counter starvation in both ad-hoc and mesh networks where CSMA protocols are deployed as the medium access mechanism. I first show that ...

In order toexplore the regulation mechanism of macadamia fruitlet abscission induced by ‘starvation stress’, a treatment girdling and defoliation was applied to bearing shoots cultivar ‘H2’ at early stage fruit development, simulating starvation stress interrupting carbon supply fruit. The levels carbohydrates, hormones, related gene expression in different tissues (husk, seed, pedicel) were in...

Cancer cells exhibit an abnormal amino acid metabolism and a dependence on specific amino acids, which might provide potential targets for treating cancer patients. In this study, we demonstrated that human triple negative breast cancer (TNBC) cells were highly susceptible to cystine starvation. We found that necrostatin-1 (Nec-1, a RIP1 inhibitor), necrosulfonamide (an MLKL inhibitor), deferox...

The main objective for the present research was to assess the effect of cyclic starvation and L- carnitine supplementation on growth (body final weight, hepatosomatic index (HSI), daily growth rate (DGI), feed conversion ratio (FCR) and voluntary feed intake (VFI)), body composition (crude protein, crude lipid, ash and moisture), biochemical (plasma total protein, glucose, cholesterol, triglyce...

Many of 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 contex...

Arabidopsis genome expression pattern changes in response to phosphate (Pi) starvation were examined during a 3-d period after removal of Pi from the growth medium. Available Pi concentration was decreased after the first 24 h of Pi starvation in roots by about 22%, followed by a slow recovery during the 2nd and 3rd d after Pi starvation, but no significant change was observed in leaves within ...

Autophagy is an intracellular degradation system activated, across species, by starvation. Although accumulating evidence has shown that mammalian autophagy is involved in pathogenesis of several modern diseases, its physiological role to combat starvation has not been fully clarified. In this study, we analysed starvation-induced gluconeogenesis and ketogenesis in mouse strains lacking autopha...

Phosphate (Pi) is a macronutrient that is essential for plant growth and development. However, the low mobility of Pi impedes uptake, thus reducing availability. Accordingly, plants have developed physiological strategies to cope with low Pi availability. Here, we report that the characteristic Arabidopsis thaliana Pi starvation responses are in part dependent on the activity of the nuclear gro...
