“Progenitor cells proliferate at the retinal margin of adult goldfish, so that the developmental stages of maturing retinal cells are arranged in temporal sequence along the periphero-central axis. We studied the caspase-dependent apoptosis of ON bipolar cells, which were labeled by an antibody to protein kinase C (PKC). In both primary and secondary growth zones of the marginal retina, PKC+cell somata were of two distinct sizes, large and small. A caspase inhibitor (zVAD-fmk),
injected into the vitreous, increased the number of both large and small PKC+somata (times approximately 2 and 1.1, respectively) in both growth zones. These data show that about one-third of immature ON bipolar cells were removed by caspase-dependent apoptosis before being incorporated into the mature retina.

“Aims: To investigate the effect of modulation of transcription factors on the fermentation properties of Saccharomyces cerevisiae industrial strains and to evaluate
whether overexpression and co-overexpression of transcription factors would result in higher ethanol yield.
Methods and Results: A mutant gene spt15 (Phe(177)Ser, Tyr(195)His, selleckchem Lys(218)Arg) was constructed by polymerase chain reaction mediated site-directed mutagenesis. The fermentation properties of the engineered strains in very high gravity fermentations were investigated. It is found that overexpression of SPT3 can enhance the resistance to ethanol and osmotic stress. On the contrary, overexpression of SPT15 or spt15 cannot obviously improve osmotic and ethanol tolerance of industrial strains. Additionally, simultaneous overexpression of SPT15 and SPT3 can not only distinctly enhance the resistance to ethanol and osmotic stress, but also improve fermentation performance.
Conclusions:
Simultaneous modulation of the expression level of SPT15 and SPT3 can increase the production of ethanol by improving osmotic tolerance and ethanol tolerance of industrial strains.
Significance and Impact of the Study: Modulation of transcription factors provides a route to fermentation phenotypes of industrial yeast strains that are not readily accessible by traditional methods.”
“Although configuration is important for the perception of biological motion, it is not known whether the processing of configuration occurs early or subsequent to local motion processing. Here we report significantly greater adaptation of the N1 event-related potential elicited by a point-light walker (PLW) following an intact PLW relative to a scrambled PLW, static intact PLW, or no adaptation.
