We studied the acute toxicity of a raw effluent from a battery manufacturing plant (Pilcam) in Douala, Cameroon, to a freshwater fish (Oreochromis niloticus), and subsequently evaluated its sub-acute effects on water quality and the biota in freshwater microscosms. The acute toxicity test was based on 96 hrs static renewal bioassays that resulted in 96-h LC50 and LC90 values of 16 and 20.7% (v/...

PURPOSE To evaluate the efficiency, accuracy, and safety of robotic percutaneous access to the kidney (PAKY) for percutaneous nephrolithotomy in comparison with conventional manual techniques. MATERIALS AND METHODS We compared the intraoperative access variables (number of access attempts, time to successful access, estimated blood loss, complications) of 23 patients who underwent robotic PAK...

Few studies have assessed the effects of tannery effluents intake in mammalian animal models, despite the discharge of tannery effluents into water bodies without treatment are environmental and public health problems in many countries. This study therefore aimed to evaluate the effects of the mice parental generation exposure to tannery effluent on the anxiety and depression behaviors in its o...

Rapid movement of agricultural chemicals through soil to groundwater via preferential flow pathways is one cause of water contamination. Previous studies have shown that time domain reflectometry (TDR) could be used to characterize solute transport in soil. However, previous studies have only scarcely addressed preferential flow. This study presents an extended application of TDR for determinin...

The effect of paper mill effluent on the physico-chemical properties of soils was studied under natural environment in pots experiment. The soil was treated to six rates of effluent viz. 5, 10 25, 50, 75 and 100 ml/Kg soil. The physico-chemical properties of the soil were determined before and at the end of the experiment, 12 weeks after irrigation with the effluent. Results revealed that among...

Objectives. Epithelial mesenchymal transition (EMT) is important for peritoneal deterioration. We evaluated the association between peritoneal solute transport rate (PSTR) and effluent markers related to EMT with adjusted values for effluent cancer antigen 125 (CA125). Methods. One hundred five incident peritoneal dialysis (PD) patients on PD for 25 (12-68) months with biocompatible solutions w...

Cosalane is a potent inhibitor of HIV replication with a broad range of activity. In this study, the hepatic disposition of cosalane was investigated with a noncirculating isolated perfused rat liver technique. When 6 microM cosalane was infused into livers from untreated rats, the drug was highly extracted by the liver (only 2. 5% of influent cosalane concentration appeared in the effluent per...

BACKGROUND Deposition of proteins on surfaces of medical devices has been recognized to putatively relate to the process of regulation of biomaterial-associated complications by attachment of fibrin clots, eukaryotic cells, and microbes. The molecules adsorb to a varying extent, depending not only on the physicochemical properties of the biomaterial, but also on the composition of the host flui...

The erythrocyte abnormality test was analyzed in kidney cells of freshwater fish, Labeo rohita exposed to tannery industry effluent. The 96h LC50 value of tannery effluent against fish was calculated by Finney method and it comes out to be 7.07%. Three sublethal concentrations on basis of 96h LC50 value (3.53%, 1.76% and 0.88%) were selected. Fishes were exposed to these concentrations for 24h,...

INTRODUCTION Early prediction of the efficacy of treatment in peritonitis complicating peritoneal dialysis (PD) is the best way to reduce morbidity. We studied the prognostic value of the third-day dialysis effluent leukocyte count after antibiotic therapy for prediction of treatment outcomes. MATERIALS AND METHODS Medical records of 31 children on PD, younger than 15 years old, admitted in A...
