Women's preferences for men's masculinized faces and voices were assessed after women (n = 331) were primed with images of male-on-male aggression, male-on-female aggression, pathogens, and neutral scenes. Male-on-male aggression and pathogen primes were associated with increased preference for masculine traits, but the same effect emerged in the neutral condition. We show the increased prefere...

Androgenetic alopecia (AGA) is a disorder that involves gradual loss of hair in genetically predisposed individuals and is more prominent in men than women. Ethnically, white male are affected the most [1]; the estimated prevalence of AGA in Caucasian populations by the age of 80 is over 90% [2]. Physiological changes which occur during AGA include hair follicle miniaturization and variations i...

BACKGROUND Office physicians are unable to measure hair quantity, hair loss, and hair growth in a simple and meaningful manner. One solution is to measure the cross-sectional area of a bundle of hair that is growing within a premeasured cross-section of scalp. OBJECTIVE The objective was to design a mechanical device that precisely measures the cross-sectional area of a bundle of hair and des...

Background: Low-level lasers are used for various medical applications including wound healing and hair loss treatment. Cell Therapy using skin stem cells could be a novel approach to hair transplantation. However, there is no study on the effect of low-level laser on the hair follicle stem cells. So, in this study, we investigated the effect of low level laser irradiation on viability and ROS ...

To investigate androgen effects on the skin pilosebaceous unit, we studied 21 male-to-female transsexuals and 17 female-to-male transsexuals receiving cross-sex hormones. At baseline and after 4, 8, and 12 months, hair growth was evaluated by the Ferriman-Gallwey score; acne by the Leeds classification; hair growth rate, density, and shaft diameter by image analysis; and sebum production by Seb...

Techniques to simulate hair in virtual humans focus on hair modeling, hair animation and hair rendering. We propose a system for modeling and animating in real time using standard OpenGL on commodity graphic cards. For styling, we propose a paint tool to determine a set of gray scale images that allow us to establish hair density and hair length values, as well as other useful parameters, and f...

Cadherin 23 and protocadherin 15 are components of tip links, fine filaments that interlink the stereocilia of hair cells and are believed to gate the hair cell's mechanotransducer channels. Tip links are aligned along the hair bundle's axis of mechanosensitivity, stretching obliquely from the top of one stereocilium to the side of an adjacent, taller stereocilium. In guinea pig auditory hair c...

Androgenetic alopecia (AGA) is a hair loss disorder affecting 80% of men and 50% of women throughout their lifetime. Therapies for AGA are limited and there is no cure. There is a high demand for hair restoration. Platelet-rich plasma (PRP), a treatment modality shown to promote wound healing, has also been explored as a treatment for AGA. This literature review was conducted to assess the effe...

OBJECTIVES The aim of this study was to estimate glycosylated hemoglobin, fasting blood sugar and lipid profile in patients with premature grayness of hair. METHODS This study was carried out from October 1999 and May 2000, at the Dermatology and Venereology Outpatient Clinic of Baghdad Teaching Hospital, Iraq. Sixty patients with premature grayness of hair and 20 healthy individuals were inc...

Plant functional traits capture important variation in plant strategy and function. Recent literature has revealed that within-species variation in traits is greater than previously supposed. However, we still have a poor understanding of how intraspecific variation is coordinated among different traits, and how it is driven by environment. We quantified intraspecific variation in wood density ...
