Artificial fingernail products are made from many chemicals, but the main one in most of these products is ethyl methacrylate (EMA). In 1974 the U.S. Food and Drug Administration outlawed a similar chemical, methyl methacrylate (MMA), used in fingernail products. MMA was proven harmful to nail technicians and customers. However, both MMA and EMA can cause contact dermatitis, asthma, and allergi...

introduction: a modern technique for elemental analysis of biological samples is laser induced breakdown spectroscopy (libs). this technique is based on emission of excited atoms, ions, and molecules in plasma produced by focusing a high power laser pulses on sample surface. because of several advantages of libs including little or no sample preparation; minimally invasive; fast analysis time a...

Although prostate cancer is among the most frequent malignancies in the elderly, this tumor may be under-reported, and it seems that its socioeconomic burden is not well-estimated. Chronic urinary obstruction caused by the cancer may cause renal failure, with hemorrhagic tendency, neurologic disturbances, cutaneous disorders, and diverse fingernail changes. Black or brown nail pigmentation has ...

Forensic practitioners and crime laboratories regularly collect and analyze fingernail evidence; however, the best techniques for processing such evidence have not been established. In this study, numerous aspects of fingernail evidence processing-collection of exogenous cells, transportation, purification of DNA, and STR analysis-were analyzed using fingernails harboring applied blood or epith...

To examine whether donor-derived cells could exist in nonhematopoietic tissues of recipients after allogeneic hematopoietic stem-cell transplantation, we examined the patterns of the short tandem repeat (STR) of DNA extracted from fingernail clippings of recipients so that the contamination of blood cells was excluded. All 21 patients reached donor-derived hematopoiesis after transplantation an...

An evaluation of treatment practices in 13 countries, not including the United States, has shown oral terbinafine to be more cost-effective (from a government payer perspective) than griseofulvin, itraconazole, and ketoconazole in the treatment of onychomycosis of toenails and fingernails. The purpose of this study was to evaluate the clinical and economic effects of oral griseofulvin, itracona...
