The article offers information on several types of anxiety. Topics discussed include information on Obsessive-Compulsive Disorder in which people have excessive, compulsive behaviours wherein they are not able to control their thoughts and actions; information on Specific phobias in which individual is either confronted or is anticipating to confront in the near future; and information on Bipolar depression where simultaneous stints in moods.

Mammalian cells have two fundamentally different states, proliferative and quiescent, but our understanding of how and why cells switch between these states is limited. We previously showed that actively proliferating populations contain a subpopulation that enters quiescence (G0) in an apparently stochastic manner. Using single-cell time-lapse imaging of CDK2 activity and DNA damage, we now show that unresolved endogenous replication stress in the previous (mother) cell cycle prompts p21-dependent entry of daughter cells into quiescence immediately after mitosis. Furthermore, the amount of time daughter cells spend in quiescence is correlated with the extent of inherited damage. Our study thus links replication errors in one cell cycle to the fate of daughter cells in the subsequent cell cycle. More broadly, this work reveals that entry into quiescence is not purely stochastic but has a strong deterministic component arising from a memory of events that occurred in the previous generation(s).

Before DNA fingerprinting analysis, many biochemical and histopathological testing are conducted on a forensic biological sample. The samples are exposed to cytological and nuclear binding dyes for their visualization under a microscope. The present study assessed the usability of these biological samples exposed to 21 routinely used histological and nuclear binding dyes for forensic DNA examination in a simulated experiment. Wright's stain, Hematoxylin, Coomassie Brilliant Blue, and Evan's Blue did not show any effect on the amplification of autosomal STR markers. Y-STRs showed higher robustness in presence of 10 dyes. Wright's stain showed the least effect on the generation of complete autosomal and Y-STR profiles. Mobility issues in capillary electrophoresis were observed in the presence of Eosin yellowish, Coomassie Brilliant Blue, and Hematoxylin for autosomal STRs and Wright's stain, Orcein, Malachite Green, Nigrosin, Bromophenol blue, and Fast green for Y STRs. Peak heights of the respective Y STR markers showed a mixed result in comparison to the positive control. In autosomal STR analysis, the peak heights showed a sharp decrease in comparison to the positive control.

Live-cell imaging demonstrates that a subset of neuroblastoma cells evades chemotherapy-induced death if they are in early G1 phase of the cell cycle at the time of drug treatment andhave sufficiently high levels of MYCN.
