Evolution of female choice under intralocus sexual conflict and genotype-by-environment interactions [PDF]
Li, X. Y., & Holman, L. (2018). Evolution of female choice under
intralocus sexual conflict and genotype-by-environment interactions. Phil.
Trans. R. Soc. B, 373(1757), 20170425, 2018 In many species, females are hypothesised to obtain 'good genes' for their offspring by mating with males in good condition. However, female preferences might deplete genetic variance and make choice redundant. Additionally, high-condition males sometime produce low-fitness offspring, for example because of environmental turnover and gene-by ...

FEBS Open Bio, EarlyView.In the blood–testis barrier, occludin is crucial for tight junctions. This study demonstrates that occludin‐targeting short peptides disrupt junction integrity, inducing immune cell infiltration, tumor necrosis factor‐α/interleukin‐6 secretion and mitochondrial dysfunction, ultimately triggering apoptosis.

Simulating Male Selfish Strategy in Reproduction Dispute [PDF]
, 2002 We introduce into the Penna Model for biological ageing one of the possible male mechanisms used to maximize the ability of their sperm to compete with sperm from other males. Such a selfish mechanism increases the male reproduction success but may decrease the survival probability of the whole female population, depending on how it acts.
