The examination of hair collected from crime scenes is an important and highly informative discipline relevant to many forensic investigations. However, the forensic identification of animal (non-human) hairs requires different skill sets and competencies to those required for human hair comparisons. The aim of this is paper is not only to highlight the intrinsic differences between forensic hu...

A frequently unrecognized and potentially devastating form of penile strangulation is that caused by human hair. Hair tourniquet syndrome frequently occurs during the time period when post partum mothers are experiencing increased hair loss. The majority of cases are thought to be accidental, however possibility of child abuse should be considered in every case.

In this review article we summarize current knowledge on how variation on the DNA level influences human pigmentation including color variation of iris, hair, and skin. We review recent progress in the field of human pigmentation genetics by focusing on the genes and DNA polymorphisms discovered to be involved in determining human pigmentation traits, their association with diseases particularl...

BACKGROUND Blood agar is used for the identification and antibiotic susceptibility testing of many bacterial pathogens. In the developing world, microbiologists use human blood agar because of the high cost and inhospitable conditions for raising wool sheep or horses to supply blood. Many pathogens either fail to grow entirely or exhibit morphologies and hemolytic patterns on human blood agar t...

Objective; In studies of the sensory epithelium of vestibular organs, regeneration of hair cells was observed. Regeneration capability of hair cells may be considered to suggest the presence of endogenous stem cells that could regenerate damaged hair cells in these organs. Therefore, we tried to show that human vestibular sensory epithelium contains cells that display proliferating characterist...

Hair cortisol concentration differs across site and person: Localisation and consistency of responses to a brief pain stressor. 1 Hair cortisol responses Summary Although in vitro studies have shown that cortisol concentrations in human and animal hair respond to environmental stressors, few data have been reported regarding the in vivo variability of hair cortisol to brief pain stressors. As a...

The stress hormone cortisol (CORT) is slowly incorporated into the growing hair shaft of humans, nonhuman primates, and other mammals. We developed and validated a method for CORT extraction and analysis from rhesus monkey hair and subsequently adapted this method for use with human scalp hair. In contrast to CORT "point samples" obtained from plasma or saliva, hair CORT provides an integrated ...

HAIR In the previous chapters a frame work for synthesis of photo-realistic hair images has been presented. In this chapter a discussion of the inverse problem will be made: Assuming that photographs of a hairstyle and the hair geometry are given, we are addressing the estimation of the BCSDF of the hair fibers. Such an image-based reconstruction can be valuable for many areas of application. F...

Hair is composed of proteins, lipids, water, and small amounts of trace elements. All proteins in animal and human bodies are built from permutations of amino acid molecules in a polypeptide string. The polypeptide chains of protein keratin are organized into filaments in hair cells. Hair is one of the most difficult proteins to digest or solubilize. Among the most common dissolving procedures ...

Syntaxin is one of several proteins that may be involved in the docking of synaptic vesicles, synaptic vesicle recycling, and non-synaptic membrane trafficking. Presence of syntaxin has been reported in rat auditory and vestibular end organs. In the current study, we have examined the expression of message for syntaxin 1 in hair cells of the sacculus of the rainbow trout, Oncorhynchus mykiss, w...
