In this study, researchers found that alkylating chemotherapy causes hair follicle stem cells to lose their regenerative ability by initially triggering proliferation followed by apoptosis, leading to permanent regeneration loss.

Amenorrhea is when a woman doesn't have periods, with primary amenorrhea starting by age 15 or within five years of breast development, and secondary amenorrhea when periods stop for three months. It affects 3-4% of women not pregnant, breastfeeding, or in menopause, mainly due to polycystic ovary syndrome, hypothalamic amenorrhea, hyperprolactinemia, and ovarian failure.

This study found that facial rejuvenation surgery led casual observers to perceive patients as younger, more attractive, and more successful and healthy, suggesting significant societal benefits beyond a youthful appearance.

This study found that men appearing in photos after a hair transplant were perceived by observers as younger, more attractive, more successful, and more approachable compared to their pretransplant images.

Amenorrhea, or the absence of periods, should be evaluated by age 15 or within five years of early breast development, and is most commonly caused by conditions like polycystic ovary syndrome and hypothalamic amenorrhea.

In this study, amitraz was found to be an effective and well-tolerated treatment for resolving sarcoptic mange in alpacas, demonstrating no relapse over a 10-month follow-up.

This study reported that Indian hedgehog (Ihh) signaling plays a crucial role in regulating tumor progression and metastasis in epithelial cancers, with Ihh deficiency leading to increased malignancy and metastasis in mice.
