It is marked by extreme kinkiness of hair in Caucasians. Woolly hair is either alre...

A nswer: Hair provides no vital function but does protect the surface of the skin, conserves body heat, and contributes to self-image. Hair is associated with femininity (e.g., long hair) and masculinity (e.g., facial hair) and, for many, closely associated with sexuality (DeVillez, 2003; Ehmann, Sheehan, & Decker, 1991). Although not considered life threatening, chemotherapy-induced hair loss ...

rodents are sensitive species to and proper monitors of heavy metals in the environment. the accumulation of copper (cu), zinc (zn) and chrome (cr) were measured by wet digestion method and using an icp-oes instrument in hair and liver of persian jird (meriones persicus) in darreh zereshk copper mine, yazd without considering the effects of surrounded mines. results indicated that the concentra...

In computer graphics, modeling the geometry of hair and hair-like patterns such as grass and fur remains a significant challenge. Hair strands can exist in an extensive variety of arrangements and the choice of an appropriate representation for tasks such as hair synthesis, fitting, editing, or reconstruction from samples, is non-trivial. To support such applications we present a novel mathemat...

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...

Loss of cochlear hair cells in mammals is currently believed to be permanent, resulting in hearing impairment that affects more than 10% of the population. Here, we developed two genetic strategies to ablate neonatal mouse cochlear hair cells in vivo. Both Pou4f3(DTR/+) and Atoh1-CreER™; ROSA26(DTA/+) alleles allowed selective and inducible hair cell ablation. After hair cell loss was induced a...

objective: to report a case of trichotillomania that was resistant to pharmacological treatment but responded well to a behavioral therapy program based on habit reversal. method: the patient was a 47-year-old lady. her problem had started at the age of seventeen. she had experienced several treatments including full doses of antidepressants, mood stabilizers, antipsychotic, and benzodiazepines...

Mechanoelectrical transduction channels of hair cells allow for the entry of appreciable amounts of Ca(2+), which regulates adaptation and triggers the mechanical activity of hair bundles. Most Ca(2+) that enters transduction channels is extruded by the plasma membrane Ca(2+)-ATPase (PMCA), a Ca(2+) pump that is highly concentrated in hair bundles and may be essential for normal hair cell funct...

BACKGROUND Hair dryers are commonly used and can cause hair damage such as roughness, dryness and loss of hair color. It is important to understand the best way to dry hair without causing damage. OBJECTIVE The study assessed changes in the ultra-structure, morphology, moisture content, and color of hair after repeated shampooing and drying with a hair dryer at a range of temperatures. METH...

Single hair follicles go through regeneration and involution cycles. In a population, hair follicles may affect each other during anagen re-entry, thus forming propagating regenerative hair waves. We review these regenerative hair waves and complex hair cycle domains, which were recently reported in transgenic mice. Two non-invasive methods to track the propagating hair wave in large population...
