This study identified compounds like hexadecanoic acid, alphaspinasterol, and squalene in Cucurbita pepo roots, which may offer new pharmacological approaches for developing therapies for various conditions.

This study found that α-spinasterol treatment significantly reduced testosterone propionate-induced prostatic hyperplasia in rats, suggesting potential benefits for managing benign prostatic hyperplasia.

This study found that the petroleum ether extract of Citrullus colocynthis fruit and an isolated steroidal compound may reduce prostatic hyperplasia in rats induced by testosterone, suggesting potential use in managing androgen-dependent conditions.

This study found that components derived from Uromedic® pumpkin seeds, especially Δ7-sterols, may inhibit DHT production and AR binding, potentially benefiting prostate and bladder health by moderating these mechanisms.

This review discusses the potential benefits of pumpkin seed oil for men's health, particularly in conditions such as benign prostatic hyperplasia, overactive bladder, and androgenic alopecia, but reports no new clinical results.

This review examines around 68 plant sources from six major plant families, assessing their scientific rationale and use by the cosmeceutical industry for applications like anti-ageing and sun protection.

This study suggests that while complementary and alternative treatments for hair loss are becoming more popular, their effectiveness and mechanisms remain largely unverified.

In this study, the researchers investigated the plant Vitex negundo and its active ingredients, noting that both natural and synthetic derivatives exhibit concentrated biological activity, which may explain the plant's traditional use in treating various ailments such as depression, malaria, and skin diseases.

This review explores how herbal hair oils made from ingredients like amla and hibiscus may offer benefits such as reducing hair loss and dandruff, but these are summarized from existing research rather than new experimental data.

This study analyzed the therapeutic potential of various plant species for alopecia areata treatment, highlighting their possible benefits due to anti-inflammatory and immunomodulatory properties, though more research is needed to fully understand the mechanisms involved.

This study found that Argan press cake extracts stimulated hair growth and reduced inflammation and oxidative stress in human hair follicle dermal papilla cells, suggesting potential for anti-hair loss drug development.

This review explores the role of transient receptor potential vanilloid channels in the pathogenesis of osteoarthritis but reports no new clinical results.

This review discusses the chemical composition, potential health benefits, and extraction methods of red ginseng oil, and reports no new clinical results but emphasizes safety and proposed molecular mechanisms.

This study found that 87% of patients with stage IIA and IIB melanoma treated with low-dose alpha-interferon reported cutaneous side effects, with the most common being hair loss.

This study concluded that alpha(1)-adrenoceptor antagonists are more effective than finasteride in the short term for reducing symptoms of lower urinary tract symptoms associated with benign prostatic hyperplasia.

This study observed that finasteride use among men with benign prostatic hyperplasia was associated with a decreased incidence of low-grade prostate cancer but not high-grade tumors.

This article reviews hair growth patterns in humans and laboratory animals, noting the random distribution of active and inactive hair follicles and differences in regional coordination among animal species, and reports no new results.

In this study, researchers found that intestine-derived human alpha defensin 5 enhances wound healing, reduces bacterial load, and promotes hair growth in murine burn wound beds by increasing LGR stem cell migration.

This study suggests that the absence of alpha5(IV)/alpha6(IV) chains in certain subepidermal basement membrane spots may relate to interactions with melanocytes in human skin.

This study found that α-MSH administration before skin wounding in adult mice reduced inflammation and scar area, suggesting a potential pathway to more regenerative healing.

This study found that the molecular structure of hair is more sensitive to synchrotron X-ray radiation than its supramolecular architecture, indicating potential concerns for biological analyses using such radiation.

In this study, severe hair loss occurred in PKC epsilon transgenic mice treated with DFMO during skin tumor prevention, highlighting a link between polyamine biosynthesis, hair follicle maintenance, and metastasis suppression.

In this study, the researchers reported extensive gene loss and high pseudogenization rates of α-keratin genes in cetaceans compared to terrestrial mammals, likely linked to hair loss and aquatic adaptations.

This study found that using a combination of Alginate-TEMPO-oxidized cellulose nanofiber-α-tocopherol membranes and Pluronic-α-tocopherol hydrogels facilitated better wound healing in diabetic rats through enhanced angiogenesis and no observable toxicity compared to using each treatment individually.

This study found that low-dose topical alpha-terthienyl combined with UVA radiation can induce cutaneous photosensitization in guinea pigs, suggesting a possible photochemotherapy approach for skin diseases like psoriasis.

This study investigated the use of dissolving microneedle patches to improve the skin-lightening effects of alpha-arbutin and resveratrol, finding that the patches enhanced intradermal delivery and slightly decreased the melanin index without affecting skin hydration or causing irritation over 24 hours.

This study found that alpha-tocopherol acetate did not demonstrate any protective effect against hair loss induced by doxorubicin in patients with solid tumors.

This article reviews the diverse regulatory roles of alpha-melanocyte-stimulating hormone in skin biology, highlighting its potential involvement in maintaining tissue homeostasis and protecting against inflammation-induced DNA damage but reports no new clinical findings.

ACTH promotes hair growth in mink, but α-MSH does not.

This study found that combining 5-alpha reductase inhibitors with alpha-blockers provided the best symptomatic relief and reduced the risk of clinical progression for BPH, while PDE5 inhibitors could offset sexual side effects.
