research SEASONAL DERMATOPATHY AND CONCURRENT REPRODUCTIVE FINDINGS IN CAPTIVE FOSSA (CRYPTOPROCTA FEROX)
Hormonal changes during the reproductive cycle may cause seasonal skin problems in captive female fossas.
research Plucked human hair as a tissue in which to assess pharmacodynamic end points during drug development studies
Plucked human hair can be used to study drug effects on certain cell markers.
research Multiphoton microscopic imaging of rabbit dorsal skin
Multiphoton microscopy effectively images rabbit skin structures in detail without staining and shows differences from human skin.
research Testosterone-stimulated weanlings as an alternative to castrated male rats in the Hershberger anti-androgen assay
Using testosterone-stimulated weanling rats can effectively replace castrated rats for anti-androgen testing, reducing animal stress.
research Perceived predation risk predicts glucocorticoid hormones, but not reproductive success in a colonial rodent
Prairie dogs with fewer neighbors are more stressed but their number of babies isn't affected.
research Characterization of Growth Secondary Hair in Min Pig Activated by Follicle Stem Cell Stimulated by Wnt and BMP Signaling Pathway
Wnt and BMP pathways stimulate hair growth in Min pigs, with Wnt being more effective.
research Small animal models of thermal injury
research Restoration of hair growth with topical diphencyprone in mouse and rat models of alopecia areata
Topical diphencyprone helped regrow hair in mice and rats with a condition similar to human hair loss.
research The mouse frizzy (fr) and rat ‘hairless’ (frCR) mutations are natural variants of protease serine S1 family member 8 (Prss8)
The frizzy mouse and hairless rat mutations are due to changes in the Prss8 gene.
research INDUCTION OF PSORIASIFORM CHANGES IN GUINEA PIG SKIN BY PROPRANOLOL
Propranolol combined with injections caused skin changes in guinea pigs but didn't fully mimic psoriasis.
research Hedonic sensitivity to natural rewards is affected by prenatal stress in a sex-dependent manner
Prenatal stress changes how male and female rats enjoy rewards differently, linked to sex hormones.
research Androgens and the hair follicle. Cultured human dermal papilla cells as a model system.
research Barbering in Laboratory Rodents: Problems and Prospects
Understanding barbering in lab rodents is important for animal welfare and research accuracy.
research Estrogen-Dependent Ontogeny of Sex Differences in Somatostatin Neurons of the Hypothalamic Periventricular Nucleus*
Male rats have more somatostatin neurons than females due to testosterone converting to estrogen during early development.
research A mutation in MAP2 is associated with prenatal hair follicle density
A mutation in the MAP2 gene causes reduced hair follicle density, leading to hairlessness.
research Allopregnanolone is required for prepulse inhibition deficits induced by D1 dopamine receptor activation
Allopregnanolone is needed for certain brain processing issues caused by D1 dopamine receptor activation.
research Increased anxiety‐like phenotype in female guinea pigs following reduced neurosteroid exposure in utero
Female guinea pigs exposed to less allopregnanolone before birth showed more anxiety-like behavior.

research [Peptidergic innervation in the sinus hair follicles of several mammalian species].
Sinus hair follicles in mammals have different nerve fiber types with species-specific patterns, especially in cats.
research Testing the impact of trait prevalence priors in Bayesian-based genetic prediction modeling of human appearance traits
Using trait prevalence priors in genetic prediction models for appearance traits is currently impractical due to limited knowledge and potential accuracy issues.
