The Effects of Starvation on Human Health

People becomehungry when their blood-glucose levels drop significantly below their setpoint and that they become satisfied after eating, when their blood-glucoselevels return to that set point. Most of the research has focused either on chronicstarvation at one end or on missing a single meal at theother end. Skipping breakfast affectscertainaspects of cognition, such as problem-solving abiliti...

TheGalactic Center – anAGN on a starvation diet

The Galactic Center shows evidence for the presence of three important AGN ingredients: a Black Hole (M• ∼ 10 M⊙), an accretion disk (10 −8.5 − 10M⊙/yr) and a powerful jet (jet power ≥ 10% disk luminosity). However, the degree of activity is very low and can barely account for the energetics of the whole central region. Neverthelss, in the very inner arsecond the central engine becomes dominant...

Evolutional Selection and Coexistence on Starvation Measure

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...

Chronic Starvation

Studies on the effect of starvation on mycobacteria.

Ten cultures of Mycobacterium tuberculosis, one of Mycobacterium kansasii (nonsignificant), and one of Mycobacterium phlei were submitted to starvation. As a result they lost first their acid fastness and then all other staining affinities but, in this chromophobic state, they survived for at least 2 years and, after that time, produced cultures of acid-fast bacilli when transferred onto nutrie...
