To the Editor: Aesthetic improvement of eyebrows or their reconstruction after damage caused by trauma or burns is not an uncommon procedure in the field of hair transplantation. The usual hair donor source for such transplantation is the scalp-occipital area. 2, 3 However, this option is not feasible in some instances because the hair is both too coarse and grows excessively long for the inten...

Epithelial stem cells (EpSCs) in the hair follicle bulge are required for hair follicle growth and cycling. The isolation and propagation of human EpSCs for tissue engineering purposes remains a challenge. Here we develop a strategy to differentiate human iPSCs (hiPSCs) into CD200(+)/ITGA6(+) EpSCs that can reconstitute the epithelial components of the hair follicle and interfollicular epidermi...

To determine whether hair is excessively glycosylated in diabetes mellitus 4 cm hair samples were taken proximally from behind the ear in 50 white non-diabetics and 46 diabetics. Hair glycosylation was assayed by a modification of the thiobarbituric acid reaction. Blood was taken from the diabetics at the same time for measurement of glycosylated haemoglobin concentration. The mean (1 SD) conce...

Permanent waving is very popular in Japan. Polypeptide chains (main chains) form the principal components of hair, and they are lined up longitudinally. Hair relaxation is also called straight permanent waving, and there are methods that change curly or wavy hair into straight hair. Hair damage as a result of winding, combing, and using high-temperature hairdressing irons is also often seen. By...

This paper presents a practical approach to the animation of hair at an interactive frame rate. In our approach, we model the hair as a set of particles that serve as sampling points for the volume of the hair, which covers the whole region where hair is present. The dynamics of the hair, including hair-hair interactions, is simulated using the interacting particles. The novelty of this approac...

Creating natural looking hair motion is considered to be one of the most difficult and time consuming challenges in CG animation. A detailed physics-based model is essential in creating convincing hair animation. However, hair animation created using detailed hair dynamics might not always be the result desired by creators. For this reason, a hair simulation system that is both detailed and edi...

BACKGROUND: Hair loss is a common complaint among women and may be associated with psychological disturbances. OBJECTIVES: This study investigated dermatology patients with respect to the prevalence of complaints of hair loss and the association between these complaints and symptoms of depression. METHODS: A cross-sectional study was conducted with female outpatients over 20 years of age with n...

AIMS Analysis of ethyl glucuronide (EtG), a minor metabolite of ethanol, is a valid tool for the assessment of social and chronic excessive alcohol consumption. Standardized analysis of EtG is usually done in head hair. As head hair cannot always be provided, alternative hair matrices become more and more interesting. Therefore, a study was performed that compared the intra-individual EtG conce...

the obstacles towards this pursuit not only negatively affect the views and perceptions of the forest villagers about forest resources but also, from time to time, causes turkey, which has the appropriate environment in terms of livestock, to become one of the countries that import meat. in this study, the perception and views of hair goat breeders about forestry & livestock breeding relati...
