research Standardization of Hibiscus rosa-sinensis Flower by HPTLC, HPLC and AAS
The method ensures Hibiscus rosa-sinensis flower extract is safe and effective for medicinal use.
research Dehydroepiandrosterone- and glucose-6-phosphate-dehydrogenases in the hair cycle of the rat
research Increased frequency of heterozygoshy for the 21 hydroxylase deficiency among hersute females
Women with excessive hair growth or polycystic ovary disease may more often carry a gene variant for 21 hydroxylase deficiency.
research [Trichothiodystrophy: a morphological and biochemical study].
Trichothiodystrophy involves brittle hair due to low sulfur amino acids, not a transport defect.
research Iron content of hair in children in various states of iron balance
Children's hair needs only a little iron for normal growth, regardless of their body's iron levels.
research The determination of endogenous steroids in hair and fur: A systematic review of methodologies
research Measuring steroids in hair opens up possibilities to identify congenital adrenal hyperplasia in developing countries
Hair steroid measurement is an effective method to diagnose and monitor CAH in developing countries.
research Hydroxylation of dehydroepiandrosterone in human scalp hair folhcles
The enzyme system in hair follicles is similar to the liver's and is affected by certain inhibitors.
research Metabolic Regulation of Hematopoietic Stem Cells in the Hypoxic Niche
Low oxygen areas help maintain and protect blood stem cells by using a simple sugar breakdown process for energy and managing their activity levels.
research THE GRADE OF HIRSUTISM CORRELATED TO SERUM ANDROGEN LEVELS AND HORMONAL INDICES
Hirsutism severity is linked to androgen levels, especially in women with a lower LH/FSH ratio.
research Trichohyalin: Purification from Porcine Tongue Epithelium and Characterization of the Native Protein
research Tyrosinase inhibition due to interaction of homocyst(e)ine with copper: the mechanism for reversible hypopigmentation in homocystinuria due to cystathionine beta-synthase deficiency.
Lowering homocyst(e)ine levels can reverse skin and hair lightening by restoring enzyme activity needed for pigmentation.
research Biochemistry of skin in health and disease
Carruthers' work advances understanding of skin biochemistry but needs clearer interpretation and more discussion on certain topics.
research Quantitative Single-Cell Approaches to Stem Cell Research
New single-cell analysis techniques are improving our understanding of stem cells and could help in treating diseases.

Canine hair follicle cells show stem cell properties, aiding hair growth.
research Revisiting hyper- and hypo-androgenism by tandem mass spectrometry
The document concludes that using LC-MS/MS for measuring androgens is more accurate than older methods, but it needs careful validation and standardized references to be most effective.
research A cDNA encoding the human type I hair keratin hHa1
hHb1, hHb3, and hHb6 mRNAs start expressing at the same time in hair follicles.
research Invalidation of a commercially available human 5α-dihydrotestosterone immunoassay
