Assessing the genetic contribution of Neanderthals to non-disease phenotypes in modern humans has been difficult because of the absence of large cohorts for which common phenotype information is available. Using baseline phenotypes collected for 112,000 individuals by the UK Biobank, we can now elaborate on previous findings that identified associations between signatures of positive selection ...

Objectives: This study was designed to investigate the potential Phyllanthus niruri extracts in promotion of hair growth. Materials and Methods: Here, we studied the hair growth promoting activity of petroleum ether extract of P. niruri following its topical administration. Alopecia was induced in albino rats by subcutaneous administration of testosterone for 21 days. Evaluation of hair loss in...

grapevine rootstocks are of the potential to increase cultivars, adaptation to different climates, soil types and a variety of unfavorable conditions. considering the existence of a rich grapevine germplasm in iran, it is possible to pick up vigorous genotypes and cultivars as drought tolerant rootstocks for commercial use due to their vast genetic potential. in this study, 698 fruitful genotyp...

Pigmentation of the skin, hair, and eyes varies both within and between human populations. Identifying the genes and alleles underlying this variation has been the goal of many candidate gene and several genome-wide association studies (GWAS). Most GWAS for pigmentary traits to date have been based on subjective phenotypes using categorical scales. But skin, hair, and eye pigmentation vary cont...

Follistatin (FST) is involved in hair follicle morphogenesis. However, its effects on hair traits are not clear. This study was designed to investigate the effects of FST gene single nucleotide polymorphisms (SNP) on wool quality traits in Chinese Merino sheep (Junken Type). We performed gene expression analysis, SNP detection, and association analysis of FST gene with sheep wool quality traits...

Research has shown that human partners are more similar than expected by chance on a variety of traits. Studies examining hair and eye colour show some evidence of positive assortment. Positive assortment may reflect attraction to self-similar characteristics but is also consistent with attraction to parental traits. Here, we examine self-reported partner hair and eye colour and the influence t...

BACKGROUND AND AIMS Root hair density (i.e. the number of root hairs per unit root length) in Arabidopsis thaliana varies among individual plants in response to different nutrient stresses. The degree of such variation, defined as inequality, serves as a unique indicator of the uniformity of response within a plant population to nutrient availability. METHODS Using the Gini coefficient (G) as...

Eflornithine 11.5% cream is an effective treatment for unwanted facial hair (UFH) in women with the effect on facial hair growth starting to be seen from 1 month after treatment initiation. TrichoScan is a validated method of assessing hair length, thickness, density, and growth rate using contact skin microscopy. The study aimed to evaluate the efficacy of eflornithine cream in women with UFH,...

Scalp involvement is a prominent and often the initial presentation in patients with psoriasis. Hair growth may be impaired with a hair loss and an increased telogen/anagen ratio. The aim of this study was to investigate the hair density and anagen/telogen ratio in psoriatic patients, using epiluminescence microscopy combined with digital image analysis (TrichoScan). Thirty psoriatic patients w...

BACKGROUND Quantitative estimates of the yield of follicular units (FUs) containing likely "permanent" hair for hair transplanting have been only theoretically estimated. OBJECTIVE To clarify the number of likely permanent hair follicles in potential donor areas. METHODS AND MATERIALS Thirty-four highly experienced surgeons were surveyed and estimated the number of FUs containing "permanent...
