Arsenic (As) fractions in the sediments of seven lakes from East Plain Ecoregion and six lakes from Yungui Plateau Ecoregion, China, were investigated. Results indicated that the total As concentrations in sediment samples of lakes of the East Plain Lake Ecoregion are higher than those of Yungui Plateau Lake Ecoregion. Residual As is the main fraction in sediment samples of lakes from both ecor...

The detection of lymphoid cells by routine examination of the urine after renal allotransplantation has proved to be a useful early indication of rejection. In a study of 36 rejection episodes, 20 (56%) were associated with a significant number of lymphocytes in the urine. The incidence was much higher when rejection occurred during the first month after operation (76%); lymphocytes were rarely...

Researchers have independently documented the effects of land use on rivers and threats to river management institutions, but the relationship between changes in institutional context and river condition is not well described. This study assesses the connections between resource management institutions, land use, and rivers by integrating social science, geospatial analysis, and geomorphology. ...

A 7-month-old boy was brought to the emergency department for persistent cough and difficulty in breathing. On the second day of admission, his urine was analyzed to rule out urinary tract infection. Chemical analysis of the sample was unremarkable and sediment microscopy did not show any abnormalities except for dense dark crystals (Fig. 1). Individual crystals were needle shaped, while aggreg...

We evaluated the performance of urinalysis dipsticks and microscopic urine sediment analysis as predictors of urinary tract infection (UTI) in patient visiting hospital. The samples were processed for macroscopic examination to observe Leukocyte esterase (LE) and Nitrite (NIT) by dipstick method, microscopic examination to observe pus cells, culture of urine sample on Blood agar and MacConkey a...

Progressive glomerulonephritis is the most serious feature of Henoch-Schönlein syndrome. In a series of 141 children with Henoch-Schönlein purpura 39 (28%) had abnormal urinary sediment for a duration of more than one month. This subgroup was followed up for 3.0 to 13.8 (mean 7.2) years. One child progressed to renal failure and 2 developed chronic glomerular disease. In this series most of the...

BACKGROUND Podocyte injury and its subsequent loss in urine play an important role in the pathogenesis of diabetic nephropathy; blockade of the renin-angiotensin system may ameliorate the damage. METHODS In a non-randomized setting, we studied 71 patients with diabetic nephropathy on a stable dose of angiotensin-converting enzyme inhibitor (ACEI). In 37 patients, angiotensin receptor blocker ...
