Juvenile rank acquisition is associated with fitness independent of adult rank [PDF]

, 2020
Social rank is a significant determinant of fitness in a variety of species. The importance of social rank suggests that the process by which juveniles come to establish their position in the social hierarchy is a critical component of development. Here,

Changes in the gut microbiome during fasting‐induced molting and its effects on gut–liver function

iMetaOmics, EarlyView.
During fasting, harmful microbiota and metabolites rise, triggering intestinal injury and activation of the TGF‐β signaling pathway, which enhances intestinal stem cell proliferation. Concurrently, hepatic function declines, indicated by increased hepatic and serum bile acids and upregulation of the non‐classical bile acid synthesis pathway.

Starvation-Induced Changes to the Midgut Proteome and Neuropeptides in Manduca sexta

Insects
Starvation is a complex physiological state that induces changes in protein expression to ensure survival. The insect midgut is sensitive to changes in dietary content as it is at the forefront of communicating information about incoming nutrients to the

Variation in adrenal and thyroid hormones with life-history stage in juvenile northern elephant seals (Mirounga angustirostris) [PDF]

, 2016
Interpretation of stress responses in wildlife is inadequate due to the range of natural variation and potential confounds of individual and life-history variables. In marine mammals, endocrine response data are sparse and variable across species.

Complement C3 mediates adolescent social isolation‐induced hippocampal synaptic deficits and sex‐specific emotional dysfunction

Interdisciplinary Medicine, EarlyView.
Adolescent social isolation disrupts hippocampal function and exacerbates emotional symptoms, with sex‐specific patterns, as shown by human studies. In mice, social isolation decreased hippocampal synaptic density and calcium signaling, upregulated complement proteins, and activated complement‐mediated microglial synaptic phagocytosis.

Glutamine and partially hydrolyzed guar gum promote intestinal adaptation and modulate small intestinal microbiota in high‐output stoma: A case report

JPGN Reports, EarlyView.
Abstract We report a case of a very low‐birth‐weight infant with a high‐output stoma following necrotizing enterocolitis. The patient exhibited villous atrophy and microbial dysbiosis. Supplementation with glutamine and partially hydrolyzed guar gum (PHGG) was initiated, leading to reduced stoma output, improved feeding tolerance, and appropriate ...

Nail Disorders in Systemic Conditions

JEADV Clinical Practice, EarlyView.
ABSTRACT Nail findings in children can be indicative of an underlying systemic disease. Many of these findings are seen in multiple entities and are not specific to one disease. The importance of specifically examining for these nail changes cannot be overstated.

Juvenile hormone regulates the maturation of sexually dimorphic naive ethanol olfactory preference in Drosophila melanogaster

Royal Society Open Science
The molecular mechanisms underlying the maturation of innate reward behaviours remain poorly understood. We have identified a sexually dimorphic innate reward behaviour in Drosophila melanogaster that varies depending on the age, sex and mating status in
