The Saharan silver ant Cataglyphis bombycina is one of the terrestrial living organisms best adapted to tolerate high temperatures. It has recently been shown that the hairs covering the ant's dorsal body part are responsible for its silvery appearance. The hairs have a triangular cross-section with two corrugated surfaces allowing a high optical reflection in the visible and near-infrared (NIR...

Follicular unit extraction (FUE) is becoming an increasingly popular method for hair restoration. As FUE leaves behind no linear scars, it is more suitable to harvest from various body areas including beard, chest, and extremities in hirsute individuals. Body hair characteristics such as thickness, length, and hair cycle may not completely match to that of the scalp hair. The techniques of harv...

BACKGROUND Family members of laboratory animal workers are at risk of developing allergy to laboratory animals. Little is known about the spreading of laboratory animal allergens outside the animal facilities. OBJECTIVE To assess the presence of laboratory animal allergens in dust collected from mattresses of laboratory animal workers and unexposed controls. METHODS Mouse and rat urinary pr...

Background: One of the key questions in biochemistry is why cell becomes aged and what are the involved factors? Why cell growth is stopped after some divisions and cells become senescent? This occurs in a greater frame in the whole body and cells dye after a while. Androgenetic alopecia (AGA) is characterized by a loss or decrease in hair follicle size, which could be related to the loss of ha...

Humans are unusual among mammals in appearing hairless. Several hypotheses propose explanations for this phenotype, but few data are available to test these hypotheses. To elucidate the evolutionary history of human "hairlessness," a comparative approach is needed. One previous study on primate hair density concluded that great apes have systematically less dense hair than smaller primates. Whi...

Woolly hair is an uncommon congenital anomaly of the scalp presenting with strongly coiled involving a localized area or covering entire side and occurring in non-black people. Among syndromes woolly hair, most known are Naxos syndrome, Carvajal-Huerta hair/hypotrichosis, ectodermal dysplasia-skin fragility tricho-hepato-enteric syndrome. Case characteristics: herein, we report case autosomal r...

In number (16 of 22) of infants in the Dutch laboratory rabbit breeding colony, in aged 45-65 days old, hair loss (alopecia) seen at the top of the head and around a week after the hair fall, was created in a state of complete alopecia. For determination of the cause of hair loss, after the observation and palpation the alopecic area, there have not been any swelling, abscesses, tumors. In skin...

background: due to the presence of radioactive minerals such as monazite, the beach sand of the west coast of kanyakumari exhibits high natural background radiation. hair is a good indicator of radionuclides in the human body. an attempt is taken to measure the 210po activity in human hair samples and the factors affecting it. material and methods: 210po activity was analysed in 47 individuals ...
