Amino acids were measured by ion-exchange liquid chromatography in sweat samples obtained from 22 healthy men during sauna bathing. Amino acids were also measured in plasma (collected before breakfast) and urine (24-h collections) from the same subjects. Serine, ornithine, citrulline, and aspartic acid were present in sweat in mean concentrations >10-fold their mean concentrations in plasma. In...

Immunosuppression is required for BK viremia and polyomavirus BK-associated nephropathy (PVAN) in kidney transplants (KTs), but the role of viral determinants is unclear. We examined BKV noncoding control regions (NCCR), which coordinate viral gene expression and replication. In 286 day-matched plasma and urine samples from 129 KT patients with BKV viremia, including 70 with PVAN, the majority ...

Methods and Results for application of the quantile equating method to data from 1 H-NMR analysis of urine samples. For plasma LC-MS and 1 H-NMR data, PC1–PC2 loadings plots and lists with variables having lowest B1–B2 correlation of quantile values before equating. Typical examples of plasma 1 H-NMR spectra.

background: the aim of this study was using elisa for detection of anti- schistosoma haemato­bium antibodies in both sera and urine of patients with urinary schistosomiasis. methods: thirty three sera and urine samples were collected from patients with acute schisto­somi­asis in diyala province, east of iraq in 2006.   their diseases were confirmed by find­ing   s. haematobium ova in urine exam...

BACKGROUND In Europe, synthetic corticosteroids are not allowed in animal breeding for growth-promoting purposes. Nevertheless, a high prevalence of non-compliant urine samples was recently reported for prednisolone, however, without any indication of unauthorized use. Within this context, 20β-dihydroprednisolone and the prednisolone/cortisol ratio have been suggested as potential tools to disc...

Ultra-fast liquid chromatography with a photodiode array detector for simple and rapid determination of urea in body fluids of farm animals is described. Blood plasma, milk, and urine samples are treated with trichloroacetic acid and then centrifuged. Supernatants are derivatized at room temperature using p-dimethylaminobenzaldehyde. Samples are separated using a ternary gradient of methanol in...

A simple, inexpensive and sensitive three-phase hollow fiber liquid-phase microextraction (HFLPME) coupled with high performance liquid chromatography (HPLC) with UV detection was successfully developed for determination of trace level of an anti-Histamine drug, fexofenadine, in human plasma and urine. The analyte was extracted into n-octanol that was immobilized in the wall of a porous hollow ...

Hypertonic solutions play an important role in the treatment of tissue edema. Following the induction of experimental vasogenic brain edema by occlusion of the common carotid arteries in eight rabbits, the effect of hypertonic lactated Ringer's solution (subjects), vs. isotonic lactated Ringer's solution (control), was studied on blood pressure, electrolyte (sodium, potassium, and calcium) ...

background: visceral leishmaniasis (vl) or kala azar is an infectious disease caused by various species of leishmania parasites. the aim of this study was to detect and compare the presence of anti-leishmania antibodies in the urine of vis-ceral leishmaniasis patients using elisa and dat methods. methods: a total of 30 urine samples were collected from vl patients referred to shiraz (southeast ...
