research Genetic Variants Associated with Hyperandrogenemia in PCOS Pathophysiology
Certain genetic variations are linked to increased androgen levels in PCOS, but more research is needed to understand these connections fully.
research The Role of Non-Aromatizable Testosterone Metabolite in Metabolic Pathways
Normal levels of DHT can reduce belly fat and increase muscle, but too much can lead to hair loss, prostate issues, and possibly heart disease.
research The Phytocannabinoid (–)-Cannabidiol Operates as a Complex, Differential Modulator of Human Hair Growth: Anti-Inflammatory Submicromolar versus Hair Growth Inhibitory Micromolar Effects
CBD can either reduce inflammation and not affect hair growth at low levels or inhibit hair growth at high levels.
research Correlation of Hair Mineral Concentrations with Insulin Resistance in Korean Males
Higher hair calcium to magnesium ratios and lower chromium levels in hair may indicate insulin resistance in Korean men.
research Helpful diagnostic markers of steroidogenesis for defining hyperandrogenemia in hirsute women
The study concluded that androstendione and DHEA are important for diagnosing high male hormone levels in women with excessive hair growth.
research Testosterone concentrations and oligomenorrhea in women with acne
Women with acne and irregular periods had higher active testosterone levels, which could suggest the usefulness of antiandrogen treatment.
research Tea Tree Oil Concentration in Follicular Casts After Topical Delivery: Determination by High-Performance Thin Layer Chromatography Using a Perfused Bovine Udder Model
Different tea tree oil mixtures absorb into hair follicles at varying levels, with microemulsion being the most effective.
research Hydrogen peroxide disrupts scarless fetal wound repair
Hydrogen peroxide can cause scars by changing healing processes and increasing certain protein levels.
research Expression of NAD+dependent 15-hydroxyprostaglandin dehydrogenase and protection of prostaglandins in human hair follicle
A substance called compound-1 could help increase hair growth by maintaining prostaglandin levels in hair follicles.
research Descriptive analysis of whole blood concentrations of toxic, essential, and trace elements in adult females from the MIREC-ENDO study
Most women had adequate essential elements except zinc, and lead levels were higher in peri-/post-menopausal women.
research Hétérogénéité tumorale du cancer de la prostate et infection par le SARS-CoV2 : une relation complexe impliquant les vésicules extracellulaires et le récepteur des androgènes
Extracellular vesicles and androgen receptors may help identify prostate cancer resistance and reduce SARS-CoV-2 infection.
research Idiopathic Hirsutism*
The document concludes that more research is needed to understand excessive hair growth in women with normal hormone levels and regular ovulation.
research Regeneration of Hair Follicles Is Modulated by Flightless I (Flii) in a Rodent Vibrissa Model
Flightless I protein affects hair growth, with low levels delaying it and high levels increasing hair length in rodents.
research Ovarian Hemangioma With Stromal Luteinization
The removed ovarian tumor was a rare type of blood vessel tumor that improved the patient's symptoms and hormone levels after surgery.
research Hirsutism
Excessive hair growth in women, often from high androgen levels, is usually caused by PCOS, and can be treated with hair removal, medication, and possibly weight loss.
research Changes in Expression and Function of Extrasynaptic GABAAReceptors in the Rat Hippocampus during Pregnancy and after Delivery
Pregnancy increases certain GABAA receptors in rat brains, influenced by steroid levels.
research Rat steroid 5α-reductase kinetic characteristics: Extreme pH-dependency of the type II isozyme in prostate and epididymis homogenates
The activity of a specific rat enzyme in the prostate and epididymis is highly dependent on the acidity level.
research Nonalcoholic fatty liver disease and polycystic ovary syndrome
People with PCOS, especially if obese, often have NAFLD, linked to obesity, insulin resistance, and high androgen levels.
research Selenium or No Selenium- That Is the Question in Tumor Patients: A New Controversy
There is no clear recommendation for using selenium in cancer patients; it may be beneficial to correct low selenium levels before treatment.
research Diagnostic Criteria for Polycystic Ovarian Syndrome
To diagnose Polycystic Ovarian Syndrome, two out of three signs—irregular periods, high male hormone levels, or cysts on the ovaries—are needed.
research K15 promoter-driven enforced expression of NKIRAS exhibits tumor suppressive activity against the development of DMBA/TPA-induced skin tumors
NKIRAS2 can suppress certain skin tumors but its effect on cancer varies with context and expression level.
research Hirsutism and Virilization in the Female
The chapter explains the causes of excessive hair growth and masculinization in women and how to measure hormone levels related to these conditions.
research Adrenal steroid hormone concentrations in dogs with hair cycle arrest (Alopecia X) before and during treatment with melatonin and mitotane
Melatonin and mitotane treatment led to hair re-growth in 62% of dogs with Alopecia X, but this was not always linked to normal hormone levels.
research 5α‐Reductase inhibitors and prostatic disease
5α-Reductase inhibitors can help treat hair loss, acne, and prostate issues by reducing DHT levels.
research Androgenic Alopecia: Cross-Talk Between Cell Signal Transduction Pathways
Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.
research Cold Atmospheric Plasma‐Activated In Situ Hydrogel Induces Hair Regeneration Via Immune Microenvironment Remodeling
The treatment using a special hydrogel shows promise for promoting hair growth.
research Engineered Nanovesicles from Fibroblasts Modulate Dermal Papillae Cells In Vitro and Promote Human Hair Follicle Growth Ex Vivo
