Stress levels of individuals are documented using glucocorticoid concentrations (including cortisol) in blood, saliva, urine or faeces, which provide information about stress hormones during a short period of time (minutes to days). In mammals, use of hair cortisol analysis allows for the assessment of prolonged stress over weeks and months and provides information on chronic stress levels with...

The work presented in this paper is part of the study which aims at determining the levels of elements in hair of children in Tanzania as a bioindicator of their nutrition and health. In this paper, the levels of trace elements in hair from children living in Dar es Salaam have been analysed. The analysis was carried out by long and short irradiation INAA at the reactor centre of the Institute ...

In this study a new method of preconcentration, separation and efficient measuring of so-called hollow fiber solid / liquid phase microextraction has been introduced for the determination of trace amounts of lorazepam (LRZ) in water samples, urine and hair using differential pulse voltammetry. To this end, a hybrid adsorbent material was used that involved ionic liquid assisted magnetic multi-w...

Hair cells in the statocyst of Hermissenda crassicornis respond to mechanical stimulation with a short latency (<2 ms) depolarizing generator potential that is followed by hyperpolarization and inhibition of spike activity. Mechanically evoked hyperpolarization and spike inhibition were abolished by cutting the static nerve, repetitive mechanical stimulation, tetrodotoxin (TTX), and Co(++). Sin...

Abstract With a growing number of dogs abandoned, living in shelters, and being rehomed, it is important to distinguish behavioural responses due stress our domestic companions. Cortisol involved the animals which generally enters individual’s body into “state emergency”. Prolonged can lead exhaustion, disease, death. Chronic be detected by evaluating cortisol concentration hair. Most domestica...

TRH1 is a member of the AtKT/AtKUP/AtHAK family of potassium carriers that is required for root hair elongation and AKT1 is an inward rectifying potassium channel expressed in the root epidermis, endodermis and cortex of Arabidopsis thaliana. Plants homozygous for the trh1-1 mutation form short root hairs. The Trh1(-) phenotype cannot be suppressed by growing plants homozygous for the trh1-1 mu...

BACKGROUND Cartilage-hair hypoplasia (MIM 250250) is an autosomal recessive disease with diverse clinical manifestations. The clinical phenotypes include variable degrees of bone and hair dysplasia, deficient cellular and/or humoral immunity, and a predisposition to malignancy. METHODS We performed genetic studies of a patient with disproportionate short stature and brittle scalp hair. Geneti...

Androgenetic alopecia (AGA) is a multi-cause pathology resulting in hair cycle deregulation and production of short, fine hair. New insights into follicle biology understanding AGA have brought new strategies to treat it. The aim this study was demonstrate the interest using ingredients targeting well-known innovative biological targets develop an effective anti-hair loss product. active were e...

background: one of the pollutant components that can be observed in many industrial wastewaters is formaldehyde. the biological treatment of the wastewater contaminated by formaldehyde is very difficult due to its antibacterial property. however the removal of formaldehyde using adsorption process is feasible but it may be expensive. the main purpose of this study is to examine the adsorption o...

In the field of consumer-used cosmetics for hair removal and hair growth reduction, there is a need for improved quantitative methods to enable the evaluation of efficacy and claim support. Optimized study designs and investigated endpoints are lacking to compare the efficacy of standard methods, like shaving or plucking, with new methods and products, such as depilating instruments or hair-gro...
