We studied both the shortand long-term effects of density on three life history traits of a red deer population inhabiting a temperate forest. Both male and female body mass increased when population density decreased, but male mass changed to a greater extent than female mass. Density did not influence female survival irrespective of age, however, survival of males was lower at high density fo...

Platelet rich plasma (PRP) was tested as a potential therapy for androgenetic alopecia (AGA) through two different clinical protocols in which one population (18 participants) received half-head treatment with autologous non-activated PRP (A-PRP) produced by CPunT Preparation System (Biomed Device, Modena, Italy) and the other half-head with placebo, and a second separated population in which a...

OBJECTIVE To evaluate the efficacy of oral finasteride therapy associated with an oral contraceptive containing drospirenone and ethinyl estradiol in premenopausal women with female pattern hair loss. SETTING Outpatient consultation for hair disorders at the Department of Dermatology, University of Bologna. PATIENTS AND INTERVENTION Thirty-seven women with female pattern hair loss were trea...

Insulin-like growth factor binding protein-3 (IGFBP-3) gene is important for regulation of growth and development in mammals. The present investigation was carried out to study DNA polymorphism by PCR-RFLP of IGFBP-3 gene and its effect on fibre traits of Chinese Inner Mongolian cashmere goats. The fibre traits data investigated were cashmere fibre diameter, combed cashmere weight, cashmere fib...

Human hair and eye color is unusually diverse in northern and eastern Europe. The many alleles involved (at least seven for hair color) and their independent origin over a short span of evolutionary time indicate some kind of selection. Sexual selection is particularly indicated because it is known to favor color traits and color polymorphisms. In addition, hair and eye color is most diverse in...

Introduction: A study was presented in New York 2003 investigating a proposed measurement system, the Hair Volume Index (HVI), for evaluating visual hair density. This based on idea that scalp coverage related to measured volume of given area. The results did not support this contention but rather density correlated with number hairs and shaft diameter, which led development Diame...

Female androgenetic alopecia (FAGA) is a common and distressing cause of hair loss, caused by androgens in genetically susceptible women [1, 2], in which dihydrotestosterone (DHT) binds to androgen receptors leading to miniaturization of scalp hair follicles [3]. FAGA, characterized by a specific diffuse loss of hair of the parietal or frontovertical regions ('in the crown'), where 5α-reductase...

In vitro studies were performed to characterize [3H]cocaine binding to dark and light ethnic hair types. In vitro binding to hair was selective, was reversible and increased linearly with increasing hair concentration. Scatchard analyses revealed high-affinity (6-112 nM) and low-affinity (906-4433 nM) binding in hair. Competition studies demonstrated that the potencies of 3beta-(4-bromophenyl)t...
