Dermal absorption of chlorpyrifos (CPF), an organophosphate (OP) pesticide, is important because of its popular use. Stress has been reported to exacerbate neurotoxic effects of certain OP pesticides; however, quantitative studies to corroborate this are not reported. This study correlates the changes in acetylcholinesterase (AChE) levels and neuronal counts in areas of the hippocampus to conse...

BACKGROUND AND OBJECTIVES Hyperhidrosis is a condition that affects a large percentage of the population and has a significant impact on peoples' lives. This report presents a technical overview of a new noninvasive, microwave-based device for creating thermolysis of sweat glands. The fundamental principles of operation of the device are presented, as well as the design and optimization of the ...

 Inhaled phosphine is absorbed rapidly from the lungs and distributed round the body  Inhaled or ingested zinc, aluminium and magnesium phosphides release phosphine into the respiratory tract and stomach; zinc phosphide can be absorbed intact from the gut  Dermal absorption of phosphine or phosphides is not considered a significant route of exposure  The majority of absorbed phosphine is ex...

Second-harmonic-generation (SHG) microscopy is an interesting new tool for observing dermal collagen fiber in skin. However, conventional SHG microscopy using a mode-locked Ti:sapphire laser suffers from low penetration depth and a slow image acquisition rate caused by scattering and absorption in tissue, making it difficult to use for in vivo applications on human skin. We develop an SHG micro...

I. The long-term fate of an oral dose of ['sSe]selenite was studied in three young women. 2. Urinary and faecal excretion, respiratory and dermal losses and whole-body retention of W e were measured, and also 75Se turnover in whole body, blood and tissues during a period of 16-20 weeks. 3. Intestinal absorption of [75Se]selenite by the three subjects was 70, 64 and 44 % of the dose. 4. Urinary ...
