This case report describes a boy with hypothalamic hamartoma experiencing pubertas precox and gelastic seizures, where leuprorelin therapy's effect on pubertas precox was controversial, but valproic acid effectively managed gelastic seizures.
research Synthesis, biological evaluation and molecular docking of 4-Amino-2H-benzo[h]chromen-2-one (ABO) analogs containing the piperazine moiety
This study identified novel 4-Amino-2H-benzo[h]chromen-2-one analogs as potent androgen receptor antagonists that show strong antiproliferative activity against prostate cancer cells, suggesting them as potential lead compounds for therapy development.
research Androgen Profiling by Liquid Chromatography–Tandem Mass Spectrometry (LC-MS/MS) in Healthy Normal-Weight Ovulatory and Anovulatory Late Adolescent and Young Women
This study defined menstrual phase-specific reference intervals for circulating androgen levels in young women, highlighting that anovulatory females showed higher androgen, LH, and FSH levels compared to ovulatory females.
research Re-Assessing K15 as an Epidermal Stem Cell Marker
research Androgenic alopecia is not useful as an indicator of men at high risk of prostate cancer
This study found that androgenic alopecia at an early age was associated with a lower risk of prostate cancer, contrary to assumptions about androgens' role.
research Lokaltherapie der Alopecia androgenetica mit 17α-Östradiol
This study found that topical application of hair lotion containing 17α-estradiol may reduce androgenetic hair loss, as 63% of treated patients showed a decrease in telogen hairs compared to 37% in the control group.
research Scalp hair 17‐hydroxyprogesterone and androstenedione as a long‐term therapy monitoring tool in congenital adrenal hyperplasia
This study suggests that measuring scalp hair 17-hydroxyprogesterone and androstenedione concentrations can be a promising tool for monitoring treatment in children with congenital adrenal hyperplasia.
research Borate-modified recombinant type XVII collagen microneedles loaded with IGF-1 for the treatment of androgenetic alopecia
In this study, an innovative microneedle platform loaded with IGF-1 and modified collagen was reported to significantly promote hair regeneration, enhance neovascularization, and reduce inflammation in a mouse model of androgenetic alopecia, outperforming the commonly used minoxidil treatment.
research Saccharomyces cerevisiae BLYAS, a New Bioluminescent Bioreporter for Detection of Androgenic Compounds
This study engineered a bioluminescent yeast strain responsive to androgenic chemicals, demonstrating rapid and sensitive detection suitable for high-throughput screening and environmental monitoring.
research Signal Detection for Adverse Events of Finasteride Using Korea Adverse Event Reporting System (KAERS) Database
research Assessing tolerability and physiological responses to 17α-estradiol administration in male rhesus macaques
research Metabolic study of androsta-1,4,6-triene-3,17-dione in horses using liquid chromatography/high resolution mass spectrometry
This study concluded that the best approach for detecting Androsta-1,4,6-triene-3,17-dione administration in horses is monitoring the metabolites M1b or M4 in urine, detectable up to 77 hours post-administration.
research Combination oral minoxidil and spironolactone for the treatment of androgenetic alopecia in adolescent females / supplemental files
research The relevance of collagen XVII expression in epidermal differentiation and proliferation
This study found that COL17 plays a key role in regulating epidermal keratinocyte differentiation and proliferation, influencing the expression of differentiation markers and cellular growth in specific conditions.
research Prostate-Sparing Effects in Primates of the Potent Androgen 7α-Methyl-19-Nortestosterone: A Potential Alternative to Testosterone for Androgen Replacement and Male Contraception1
This study found that MENT is 10 times more potent than testosterone in suppressing gonadotropins and contributing to anabolism in monkeys, with a potentially wider therapeutic index for human androgen replacement and male contraception.
research Alopecic and Aseptic Nodules of the Scalp (AANS): An Under- and Misdiagnosed Entity: A New Case Report of a 17-Year-Old Boy
This case report details a 17-year-old male with Alopecic and Aseptic Nodules of the Scalp successfully treated with doxycycline and intralesional corticosteroids, highlighting the importance of thorough evaluation for accurate diagnosis.
research IS AGE MORE THAN JUST A NUMBER? CHARACTERISTICS OF MEN PRESENTING FOR REPRODUCTIVE UROLOGY FERTILITY EVALUATION IN NORTH AMERICA STRATIFIED BY AGE GROUPS
This study found that older men in North America had longer infertility durations and were more likely to have partners who underwent IVF, with age impacting referral patterns and substance use behaviors.
research Novel azaandrostane derivatives for the synthesis of 17β‐(N‐tert‐butyl carbamoyl)‐4‐aza‐5α‐androst‐1‐ene‐3‐one
This study reports a new industrial process for making finasteride using novel protective groups, demonstrated through spectral data of newly prepared compounds.
research Investigation by Imaging Mass Spectrometry of Biomarker Candidates for Aging in the Hair Cortex
In this study, researchers identified three molecules in hair that varied with age, suggesting potential markers for aging and targets for cosmetic products.
research Value of hormonal levels in patients with male androgenetic alopecia treated with finasteride: better response in patients under 26 years old
This study found that finasteride 1 mg daily decreased 5alpha-dihydrotestosterone levels and improved hair growth in younger men with androgenetic alopecia, with higher initial hormone levels predicting better response.
research The promoter of an androgen dependent gene in the hamster flank organ
This study found that a gene from hamster flank organs is indirectly regulated by androgens, despite lacking direct androgen responsive elements, indicating involvement of androgen-dependent transcription factors.
research Androgenetic alopecia in adolescents.
This review discusses androgenetic alopecia in adolescents, including its prevalence and use of minoxidil topical solution, but provides no new clinical results.
research Structural Characterization and Ligand Specific Protein Interactions of Androgen Receptor
This study found that AR-007 degrades faster and has a stronger association with hsp70 than AR-014, suggesting it is less stable when bound to the androgen receptor.
research A Novel Androgen Receptor Gene Mutation in a 46,XY Patient: Complete Androgen Insensitivity Syndrome
This case report identifies a novel AR gene mutation in an adolescent with primary amenorrhea, suggesting that CAIS should be considered when evaluating patients with a female phenotype and breast development.
research Signaling from keratins
In this study, researchers at Johns Hopkins University found that Keratin 17 plays a signaling role in cell growth during a wound response by aiding mTOR pathway activation, beyond its structural functions.
research Puberty in Boys: Correlation of Plasma Levels of Gonadotropins (LH, FSH), Androgens (Testosterone, Androstenedione, Dehydroepiandrosterone and Its Sulfate), Estrogens (Estrone and Estradiol) and Progestins (Progesterone and 17-Hydroxyprogesterone)
