Infrared Thermometry for Acute Radiation Syndrome in Mice.

Experiment on female ICR CD-1 mice showed that non-contact infrared thermometry can be used for short-term and medium-term prognosis of animal death during the development of acute radiation syndrome. In mice irradiated with X-rays in a dose of 7.25 Gy (LD), the body temperature 1 and 5 days before death was below the normal limit (<36.

Whi3 mnemon association with endoplasmic reticulum membranes confines the memory of deceptive courtship to the yeast mother cell.

Prion-like proteins are involved in many aspects of cellular physiology, including cellular memory. In response to deceptive courtship, budding yeast escapes pheromone-induced cell-cycle arrest through the coalescence of the G1/S inhibitor Whi3 into a dominant, inactive super-assembly. Whi3 is a mnemon (Whi3), a protein that conformational change maintains as a trait in the mother cell but is not inherited by the daughter cells.

Behavioral Responses and Immune and Cytogenetic Parameters of Food-Restricted Mice.

The experiments on mice showed that subchronic food restriction to 40 and 8% of unrestricted ration is a strong stressor inducing devastation of lymphoid organs, primarily the thymus and spleen. The mice in the group with severe food restriction (8% of normal ration) demonstrated increased front paw grip force. We also observed an increase in spontaneous motor activity in these animals correlated with food restriction.

Yeast Sporulation and [SMAUG] Prion: Faster Is Not Always Better.

Chakravarty et al. (2019) and Itakura et al. (2019) report that the yeast RNA-binding protein Vts1 can convert into the [SMAUG] prion state and delay meiosis commitment in response to starvation.
