Women’s hair has been a prominent feature of many paintings, folktales, films and literary works over the centuries. Its representation aligns it with symbolic notions of femininity, female sexuality and all the ambivalent associations... more
To prove someone has had the proper training that will enable them to use aesthetic laser equipment accurately, they need a laser hair removal certification
There is accumulating evidence that the metabolism of several trace elements is altered in diabetes mellitus and that these nutrients might have specific roles in the pathogenesis and progress of this disease. The aim of present study was... more
Abstract: The purpose of this work was to correlate the amount of the food mutagen 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) determined in mouse fur with the number of intestinal tumours induced by PhIP, to further evaluate... more
Human head lice, Pediculus (humanus) capitis, infest people worldwide and are most prevalent in children. The aim of this study was to determine the prevalence of head lice, in relation to socioeconomic status of the family and hygienic... more
We optimized a mercury (Hg) speciation extraction method for human hair in combination with speciesspecific isotope-dilution analysis by gas chromatographyinductively coupled plasma-mass spectrometry (GC-ICP-MS). The method was validated... more
IBIDS is a syndrome characterized by ichthyosis, brittle hair, impaired intelligence, decreased fertility, and short stature, but unassociated with skeletal lesions. This condition is considered a form of trichothiodystrophy because hair... more
The advice on hair washing during brain irradiation is aimed at minimizing radiation induced skin toxicity. We performed a prospective randomized trial to assess the effect of advice on scalp care on the local skin reaction in patients... more
The effects of melanocyte-stimulating hormone (alpha-MSH) and related analogs on follicular melanogenesis in the mouse (C57BL/6JA gamma) were studied. [Nle4, D-Phe7]-alpha-MSH and the related fragment analogues Ac-[Nle4,... more
All existing sea otter, Enhydra lutris, populations have suffered at least one historic population bottleneck stemming from the fur trade extirpations of the eighteenth and nineteenth centuries. We examined genetic variation, gene flow,... more
The zoophilic dermatophyte Microsporum canis has cats as natural reservoir, but it is able to infect a wide range of hosts, including humans, where different clinical features of the so-called ringworm dermatophytosis have been described.... more
The termite is an insect which is a weak flier, has a large wing area in relation to its body mass, and many species typically fly during rain or storm periods. Water droplets placed on these insects' wings will spontaneously roll off the... more
Although unwanted facial hair often leads to anxiety and avoidance of social situations, evaluation of treatment outcomes in clinical trials has relied largely on measures external to the patient such as the extent of hair growth or an... more
Background: Sodium hypochlorite (NaOCl), the primary component of household bleach, has been shown to alter the purified mouse allergen Mus m 1, such that antibody recognition, or immunogenicity, is lost. Results of initial experiments... more
The article analyzes innovative production technologies and the use of lining materials used for the production of insulated footwear. The study of the heat- conducting properties of natural, artificial and non-woven materials will make... more
The sorption of explosives (TNT, RDX, PETN, TATP, EGDN) to hair during exposure to their vapors is examined. Three colors of hair were simultaneously exposed to explosive vapor. Following exposure of hair, the sorbed explosive was removed... more
In some laboratories hair testing may be the main method for the evaluation of individual's drug history, however, compelling evidence supports the possibility that the presence of a small amount of drug in hair can derive from external... more
Acute promyelocytic leukaemia (APL) is a distinctive subtype of acute myeloid leukaemias. Even through this human disease can be treated by the intravenous administration of all-trans retinoic acid (ATRA), 25% of patients typically... more
of the matched hair segment as measured by CV-AAS. Consecutive daily Hg deposition in single hairs of fish eaters was determined. Results showed that apparent daily changes in Hg concentrations within a hair segment that corresponds to 1... more
Multi-proxy approach was used to reconstruct the environmental conditions of remote lakes in the High Tatra Mountains (Slovakia) over the past few centuries (approximately 500-1000 years). Short sediment cores (*30 cm) taken from three... more
Mycorrhizal fungi are among the most common symbioses found in terrestrial ecosystems, both natural and managed. They are important for many reasons, but most notably because of their positive effects on plant growth, which are mediated... more
A fast and efficient multi-residue extraction-purification procedure was developed for 12 corticosteroids in biological matrices (hair, urine and meat), in order to control their illegal use as growth promoters in cattle. Detection and... more
Hair pigmentation is one of the most conspicuous phenotypes in humans. Melanocytes produce two distinct types of melanin pigment: brown to black, indolic eumelanin and yellow to reddish brown, sulfur-containing pheomelanin. Biochemically,... more
Androgens are important in hair growth and patterning, whereas growth hormone substitution enhances their effect in growth hormone-deficient men. No previous study has jointly evaluated the function of sex steroids, sex hormone-binding... more
The Agusan River basin of eastern Mindanao, the Philippines, hosts several centres of artisanal gold mining, the most important of which, Diwalwal, is a significant gold producer in global terms. An investigation of the environmental... more
