research Consequences of steroid-5α-reductase deficiency and inhibition in vertebrates
Lack or blocking of SRD5a, a key component in hormone creation, can lead to conditions like pseudohermaphrodism and affect hair growth, bone mass, muscle strength, and reproductive health. More research is needed on its regulation from fertilization to adulthood.
research Defining the identity of mouse embryonic dermal fibroblasts
Researchers identified specific genes that are important for mouse skin cell development and healing.
research In vivo investigation of the efficiency of a nanoparticle-emulsion containing polihexanide on the human skin
The nanoparticle-emulsion with polihexanide is more effective and lasts longer for skin antisepsis.
research The development of a solid lipid nanoparticle (SLN)-based lacticin 3147 hydrogel for the treatment of wound infections
The new gel effectively treats MRSA-infected wounds for longer.
research Functional analyses of a novel missense and other mutations of the vitamin D receptor in association with alopecia
A single amino acid change in the vitamin D receptor can disrupt its function and lead to hair loss.
research Expression of bioactive recombinant human fibroblast growth factor 10 in Carthamus tinctorius L. seeds
Scientists made safflower seeds produce a human growth factor that could help with hair growth and wound healing.
research Inhibition of 3‐methylcrotonyl‐CoA carboxylase explains the increased excretion of 3‐hydroxyisovaleric acid in valproate‐treated patients
Valproic acid treatment increases a specific acid in urine by blocking an enzyme, possibly causing skin rash and hair loss.
research Hair Loss After Metabolic and Bariatric Surgery: a Systematic Review and Meta-analysis
Many people experience hair loss after weight loss surgery, especially younger women, and it's linked to lower levels of zinc, folic acid, and ferritin.
research Pro-Insulin-Like Growth Factor-II Ameliorates Age-Related Inefficient Regenerative Response by Orchestrating Self-Reinforcement Mechanism of Muscle Regeneration
Pro-IGF-II improves muscle repair in old mice.
research New dimensions in Hirsutism
Laser hair removal is safe and effective for fair-skinned people with dark hair, and using eflornithine with laser treatments can improve results.

research Advances in medical polyesters for vascular tissue engineering
Polyesters show promise for repairing damaged blood vessels.
research New changes in pregnancy and lactation labelling: Review of dermatologic drugs
The new FDA labeling rules provide more detailed drug safety information for pregnant and breastfeeding women, but more data is needed on the risks of many dermatologic drugs.
research Investigation of intermolecular interactions in finasteride drug crystals in view of X-ray and Hirshfeld surface analysis
Finasteride crystals are held together by hydrogen bonds and weak interactions, forming synthon pseudopolymorphs.
research Virtual Bioequivalence Assessment of Ritlecitinib Capsules with Incorporation of Observed Clinical Variability Using a Physiologically Based Pharmacokinetic Model
50-mg ritlecitinib capsules are bioequivalent to 100-mg capsules.
research The influence of obesity on Androstenedione to Testosterone ratio in women with polycystic ovary syndrome (PCOS) and hyperandrogenemia
Obesity changes androgen levels in women with PCOS, leading to higher testosterone relative to androstenedione.
research External post mortem artefact: a key issue in hair result interpretation
Hair test results can be misleading due to contamination, so they shouldn't be used alone to determine drug use.
research Screening of synthetic and natural product databases: Identification of novel androgens and antiandrogens
Researchers found new potential treatments for conditions related to the androgen receptor, like male hormonal contraception, by testing thousands of compounds.
research In Vivo Investigation in Pigs of Intestinal Absorption, Hepatobiliary Disposition, and Metabolism of the 5α-Reductase Inhibitor Finasteride and the Effects of Coadministered Ketoconazole
Ketoconazole increases finasteride's effectiveness and lifespan in the body.
research Procyanidin Oligomers Counteract TGF-β1- and TGF-β2-Induced Apoptosis in Hair Epithelial Cells: An Insight into Their Mechanisms
Procyanidin compounds from apples and barley promote hair growth and prevent hair cell death.
research Extraction of Quercetin from Nothopanax scutellarium Leaves via Ionic Liquid-based Microwave-assisted Extraction
The best method to extract quercetin from these leaves is using a specific ionic liquid with salt, which is more efficient and uses fewer solvents.
