research Hair Follicle Immune Privilege Revisited: The Key to Alopecia Areata Management
Restoring hair bulb immune privilege is crucial for managing alopecia areata.
research Epithelial expression of the hormone leptin by bovine skin
Cattle skin has leptin which might control skin and hair growth.
research Efficacy of an agonist ofα-MSH, the palmitoyl tetrapeptide-20, in hair pigmentation
Palmitoyl tetrapeptide-20 may help reduce hair greying and increase melanin production.
research Ovarian sex steroid receptors and sex hormones in androgenized rats
High doses of nandrolone decanoate disrupt ovarian hormones and receptors in rats, with recovery only at lower doses and longer recovery times.
research 11β-Hydroxylase inhibitors protect against seizures in mice by increasing endogenous neurosteroid synthesis
11β-Hydroxylase inhibitors help prevent seizures in mice by boosting natural neurosteroid production.
research Stress and the Hair Follicle
Stress can cause hair loss and skin issues by affecting hair growth cycles.
research Temporal expression and steroidal regulation of piRNA pathway genes (mael, piwi, vasa) during Silurana (Xenopus) tropicalis embryogenesis and early larval development
The piRNA pathway genes are crucial in early development and may influence sex differentiation through hormone regulation.
research Role of estrogen receptor signaling in the control of the hair follicle cycle
Estrogen and its receptors play a key role in hair growth, with differences between males and females.
research Disturbance of the Circadian System in Shift Work and Its Health Impact
Shift work disrupts the body's natural clock, leading to health problems.
research Aging in the sebaceous gland
Sebaceous glands age due to genetic and environmental factors, affecting sebum production and composition.
research Is it getting in the hair? – Cortisol concentrations in native, regrown and segmented hairs of cattle and pigs after repeated ACTH administrations
Hair cortisol is a reliable stress indicator in cattle but may not be valid for pigs.
research Mechanism of action of bolandiol (19-nortestosterone-3β,17β-diol), a unique anabolic steroid with androgenic, estrogenic, and progestational activities
Bolandiol, a synthetic steroid, builds muscle and bone without greatly affecting sex glands, and works differently from other hormones.
research Elevated Ghrelin Plasma Levels in Patients with Polycystic Ovary Syndrome
Women with Polycystic Ovary Syndrome have higher levels of the hormone ghrelin, which may be linked to the cause of the condition.
research The vitamin D receptor functions as a transcription regulator in the absence of 1,25-dihydroxyvitamin D3
The vitamin D receptor can regulate genes and affect hair and hormone levels without its usual activator.
research Bilateral adrenalectomy induces early onset of summer fur growth in mink (Mustela vison)
Removing mink's adrenal glands causes their summer fur to grow earlier.
research Nutrition and acne
Diet, especially dairy and high-sugar foods, can cause acne.
research The influence of long-term treatment with cyproterone acetate or a cyproterone acetate-ethinyl oestradiol combination on androgen levels in blood of hirsute women
Both treatments reduced androgen levels and hair growth in women with hirsutism.
research Acne in transgender patients: disease management and treatment recommendations from a group of experts on acne
Transgender acne treatment requires a tailored approach with ongoing topical treatments and ceramide-rich moisturizers.
research Serum androgens and risk of atrial fibrillation in older men: The Cardiovascular Health Study
Older men with low levels of a testosterone byproduct had a higher chance of developing an irregular heartbeat.
research Discovery of Nonsteroidal Androgens
Scientists found new nonsteroidal compounds that can act like natural male hormones and might help treat male fertility and hormone issues.
research Stroke Risk Factors Unique to Women
Women have unique stroke risks due to hormones, contraceptives, pregnancy, and menopause.
research Allopregnanolone in the bed nucleus of the stria terminalis modulates contextual fear in rats
Allopregnanolone affects fear responses differently in male and female rats, possibly explaining sex differences in anxiety disorders.
research The impact of VDR expression and regulation in vivo
VDR regulation varies by tissue and is crucial for its biological functions.
research Tertiary hypothyroidism in a dog
A dog with a pituitary tumor developed tertiary hypothyroidism, improved with treatment, but was later euthanized due to neurological issues.
research Somatotropin Penetration Testing from Formulations Applied Topically to the Skin
The new topical growth hormone formula has high skin penetration and bioavailability.

The 39th Manfred Donike Workshop discussed methods for detecting misuse of steroids, gene doping, and the complexity of identifying drug residues in urine, highlighting the ongoing efforts to improve global anti-doping work.
research Impaired Prolactin-Lowering Effects of Metformin in Women with Polycystic Ovary Syndrome
Metformin lowers prolactin in women without PCOS but not in those with PCOS, where it reduces other hormones instead.
research Recent advances in neuropeptide-related omics and gene editing: Spotlight on NPY and somatostatin and their roles in growth and food intake of fish
New tools show that in fish, NPY increases feeding and somatostatin decreases it.
research Clinical Snippets
