Type I and Type II keratin chains can form heterodimers despite sequence differences.

In this study, researchers successfully synthesized a rigid 3a-arylhexahydropentalene-1,6-dione from the easily accessible starting material cyclopent-2-en-1-one, highlighting a structural motif common in natural products and pharmaceuticals.

This study found that high voltage cathode rays caused significant damage to the spermiogenic epithelium of male adult white rats, showing particular sensitivity of germinal epithelium to radiation.

A new antiandrogen compound was made and its detailed three-dimensional shape was described.

This article reviews the clinical and biochemical features of genetic mutations affecting dihydrotestosterone production and their potential role in male pseudo-hermaphroditism, but presents no new clinical results.

This study found that four new progesterone derivatives reduced prostate weight in gonadectomized hamsters, suggesting potent in vivo antiandrogenic effects similar to finasteride.

The researchers reported that compounds 11 to 13 derived from Westphalen-type steroids showed strong antiandrogenic activity in vivo, though their effects could not be attributed to 5α-reductase inhibition or androgen receptor binding.

This study found that the Transdermal Delivery System efficiently delivers testosterone systemically and showed bioequivalent hormone concentrations to a known topical gel in healthy males.

This study demonstrated that a metric based on rotational echo intensity in 2H magic-angle spinning NMR can derive kinetic information for conformational exchange without complex modelling, achieving activation barriers consistent with prior findings.

This study found that a sunscreen with oxothiazolidine and δ-tocopheryl glucoside provided complementary oxidative protection, with immediate but brief effects from oxothiazolidine and prolonged effects from the slower-absorbing δ-tocopheryl glucoside.

This study found that two new progesterone derivatives showed higher antiandrogenic effects and 5α-reductase inhibition than finasteride in hamsters, particularly reducing seminal vesicle weight and flank organ size.

This study developed a model predicting uranium excretion in human hair from drinking water exposure, suggesting it is a viable indicator for assessing internal uranium burden.

This study found that finasteride was nongenotoxic in Drosophila, while doxazosin mesylate and saw palmetto induced homologous recombination, indicating potential genotoxic actions under the test conditions.

Certain enzymes react strongly with some hormones in rat skin during hair growth, mainly in sebaceous glands and hair sheaths.

The method effectively analyzes human hair proteins, especially nonfilamentous ones.

This case report describes two patients with trichothiodystrophy who exhibited a different pattern of hair protein composition changes, suggesting a subgroup of TTD characterized by partial loss of high-sulfur proteins without significant alteration in their amino acid composition.

Accurate method measures finasteride levels in human plasma using gas chromatography-mass spectrometry.

This study presents a novel assay that allows for the simultaneous measurement of various androgens and 5α-reductase inhibitors in male serum, facilitating research into the biochemical effects of these inhibitors.

This study found that the TYK2 inhibitor deucravacitinib did not significantly improve hair regrowth in patients with alopecia areata compared to placebo, suggesting it may not be effective for this condition. No new safety issues were identified.

This study found that reintroducing certain depleted amino acids into weathered hair using cosmetic treatments can strengthen the hair, improving its look and feel and reducing damage and breakage.

This article reviews the benefits of Truman Plus Male Enhancement for testosterone levels and sexual health, but it does not present any new clinical study results.

This study found that a dutasteride tablet formulation using cyclodextrin complex, solubilizing polymer, and surfactant achieved similar bioavailability in beagle dogs to that of a commercial capsule.

This study found that Sonirid Duo, a combination of tamsulosin and finasteride, significantly improved symptoms and quality of life in patients with BPH over 12 months.

This study found that nuclear androgen receptors are not necessary for androgen self-administration, suggesting that plasma membrane receptors might be involved.

This study identified a compound heterozygous mutation in the 3 beta-HSD gene that confirmed inherited 3 beta-HSD deficiency in a Pakistani child with salt-wasting congenital adrenal hyperplasia.

This article discusses the functions of the enzyme 17beta-HSD10, including its role in steroid metabolism and potential links to Alzheimer's disease, but reports no new experimental findings.

This letter to the editor addresses corrections related to an earlier study on the effect of the dual 5α-reductase inhibitor dutasteride on markers of tumor regression in prostate cancer, but reports no new findings.

This study found that prolonged administration of DHEA improved long-term memory and brain activity balance in old rhesus macaques, with effects like increased motor activity and restored hair lasting a year.
