research Common Variants in the Trichohyalin Gene Are Associated with Straight Hair in Europeans
Common variants in the Trichohyalin gene are linked to straight hair in Europeans.
research Linear Basal Cell Carcinomas
Dr. Connelly agrees that linear basal cell carcinomas might be more aggressive but highlights the study's lack of clear criteria to identify them.
research 839 Spatiotemporal antagonism in mesenchymal-epithelial Signaling in sweat versus hair fate decision
Sweat glands and hair follicles are determined by opposing signals, with BMPs promoting sweat glands and blocking BMPs leading to hair follicles.
research Trichostasis Spinulosa
The study found clear differences in lesion distribution and microscopic features among trichostasis spinulosa, keratosis pilaris, and eruptive vellus hair cysts.
research Long‐pulsed ruby laser‐assisted hair removal in male‐to‐female transsexuals
Long-pulsed ruby laser effectively reduces hair in male-to-female transsexuals.

research BH27 When patterns blur: recognizing the overlap of alopecia areata and lichen planopilaris
A rare dual diagnosis of alopecia areata and lichen planopilaris requires thorough evaluation for effective treatment.
research Early Exposure to Sexualized Content and Androgenetic Alopecia: Can Culture Shape Our Biology?
Early exposure to sexualized content and poor lifestyle choices may lead to early hair loss.
research SAT-288 Successful Virilization of a PAIS Patient with a Missense Mutation In The Ligand-binding Domain Of The Androgen Receptor with Combined High-dose Testosterone and Aromatase Inhibitor
A 12-year-old boy with PAIS successfully developed male characteristics using high-dose testosterone and anastrozole.
research 46, XY 5-Alpha Reductase Deficiency in a 36-Year-Old Phenotypic Female Patient
A 36-year-old person with a female appearance but male chromosomes was diagnosed with a rare enzyme deficiency affecting sexual development.
research Morpho‐regulation in diverse chicken feather formation: Integrating branching modules and sex hormone‐dependent morpho‐regulatory modules
Sex hormones, especially estradiol, can change chicken feather shapes and colors.
research The Ludwig pattern of androgenetic alopecia is due to a hierarchy of androgen sensitivity within follicular units that leads to selective miniaturization and a reduction in the number of terminal hairs per follicular unit
Ludwig pattern hair loss in women results from varying sensitivity in hair follicles, causing fewer visible hairs.
research Faculty Opinions recommendation of A counter gradient of Activin A and follistatin instructs the timing of hair cell differentiation in the murine cochlea.
Activin A speeds up ear hair cell differentiation, while Follistatin slows it down.
research New familial association between ocular coloboma and loose anagen syndrome
Two siblings were the first reported cases of inheriting both eye coloboma and loose anagen syndrome together.
research Recurrent Pregnancy Loss Associated Cytogenetic and Genetic Anomalies – Study from Eastern India
Genetic variations contribute to over 10% of recurrent early pregnancy loss cases.
research Involvement of the bulge region with decreased expression of hair follicle stem cell markers in senile female cases of alopecia areata
Decreased CD200 in hair follicles may cause immune issues in some alopecia areata cases.
research Gonadal Function in Men with Cushing Syndrome
Cushing syndrome often causes low testosterone and sexual issues in men.
research Molecular epidemiology of hypospadias: Review of genetic and environmental risk factors
Both genes and environmental factors like chemicals may contribute to the increase in hypospadias, but the exact causes are still unclear.
research Development of the CLASI as an outcome instrument for cutaneous lupus erythematosus

research PMON281 PERSISTENT VIRILIZATION AND VASOMOTOR SYMPTOMS IN A TRANSMAN 5-YEARS POST TESTOSTERONE WITHDRAWAL
A transman experienced lasting virilization symptoms after stopping testosterone, which were resolved with estradiol treatment.
research Endocrine Aspects of Female Sexual Dysfunction
Hormones like estrogen, testosterone, progesterone, and prolactin play complex roles in female sexual function, with testosterone potentially improving sexual desire, arousal, and satisfaction. However, more research is needed to establish safe and effective hormone treatments for female sexual dysfunction.
