Adult bullfrog were given single intraotic injections of the aminoglycoside antibiotic gentamicin sulfate and sacrificed at postinjection times ranging from 0.5 to 9 days. The saccular and utricular maculae of normal and injected animals were examined in wholemount and cross-section. Intraotic 200 microM gentamicin concentrations resulted in the uniform destruction of the hair bundles and, at l...

Keratin is a fibrous, structured protein that constitutes the basis of different structures such as nails, hair, beak, wool, feathers, claws, and horns. Until now, keratin isolation has been carried out from waste feather, hoof hair. However, development effective techniques to obtain without any damage secondary structure remains challenging task. Here in, two distinct methods (Na2S EDTA) were...

market volatility remains one of the most important research fields in agricultural economics.interestingly, price transmission mechanism seems to be symmetric in sectors that are likely to be of high political power.this paper analyzes the price transmission effects from international markets to domestic markets for corn in iran. for this purpose, we estimate the elasticity of substitution bet...

The measurement of cortisol in hair is becoming important in studying the role of stress in the life history, health and ecology of wild mammals. The hair cortisol concentration (HCC) is generally believed to be a reliable indicator of long-term stress that can reflect frequent or prolonged activation of the hypothalamic-pituitary-adrenal axis over weeks to months through passive diffusion from...

The hair of all mammals consists of terminally differentiated cells that undergo a specialized form of apoptosis called cornification. While DNA is destroyed during cornification, the extent to which RNA is lost is unknown. Here we find that multiple types of RNA are incompletely degraded after hair shaft formation in both mouse and human. Notably, mRNAs and short regulatory microRNAs (miRNAs) ...

We offer a new perspective to the unionised wage effects of unilateral trade liberalisation by considering endogenous domestic market structure. Hence, in contrast to the existing works, which focus on the short-run effects of trade liberalisation on unionised wage, we focus on more long-run effects by considering the effects of trade liberalisation on the domestic market structure. Trade liber...

Hallermann-Streiff syndrome (HSS) is a rare genetic disorder that is primarily characterized by distinctive malformations of the skull and facial region, sparse hair, eye abnormalities, dental defects, atrophic skin changes and a proportionate short stature. Here we discuss a case of 9 years-old female child who presented with abnormal facial features, dental problems and associated cardiac pro...
