Use ethical and humane practices in mouse research.

The ND1 gene of the Asian black bear Sichuan subspecies is similar to other bear species.

Trichoblastomas in aged house musk shrews show unique features and may involve serum amyloid A in inflammation.

The C3H/HeJ mouse model is useful for studying and testing treatments for alopecia areata.

Hairlessness in mammals is caused by combined changes in genes and regulatory regions.

Biotin deficiency in monkeys causes fur and skin issues, but 20 μg of biotin daily can prevent or cure it.

Humans, especially vulnerable groups, can catch skin infections from small mammals.

Bats in Puebla, Mexico, show hair loss likely due to environmental stress from human activities.

Fungal infections in lab animals can interfere with research.

All adults have Demodex mites, which vary by region.

Gonadal hormones may influence sex differences in play fighting in animals, but their effect on human spatial behavior is unclear and needs more research.

RU58841, an androgen receptor blocker, significantly increased hair density, thickness, and length in monkeys when applied topically daily for several months.

Pig skin is a good substitute for human skin to measure drug absorption, but differences in skin structure and enzymes across species must be considered.

Minoxidil metabolizes similarly in monkeys and humans, but differently in dogs and rats.

Testosterone can slow hair growth in adult monkeys, but a blocker called RU 58841 can counteract this and potentially help hair regrow.

Stress likely causes hair loss in Formosan macaques.

The procedure reliably measures cortisol in rhesus macaque hair.

The model using human skin on mice helps study human sebaceous glands.

Rhino mice show significant meibomian gland changes, making them a potential model for studying gland disorders.

Researchers mapped and categorized specific keratin-associated protein genes on human chromosome 21q22.1.

Hairless mammals evolved quickly in both gene and non-gene areas related to skin and hair.

Hair dyes penetrate the scalp very minimally, less than 1%.

Prdm1 is necessary for early whisker development in mice but not for other hair, and its absence changes nerve and brain patterns related to whiskers.

The wolves suspected of man-eating in the 1880s likely ate very little human flesh and mostly consumed a diet similar to herbivores and omnivores.

Porcine PRP can replace FBS and promote hair growth.

Indian bison, black buck, and nilgai have distinct hair follicle patterns useful for species identification.

Progesterone's anesthetic effects don't rely on progesterone receptors.

Different species and human skin models vary in their skin enzyme activities, with pig skin and some models closely matching human skin, useful for safety assessments and understanding the skin's protective roles.

Finasteride metabolites found in pigs match human studies, making pigs a valid model for human drug research.

Some masked palm civets in Japan have a skin disease caused by mites.
