Open-cast mining for Ni, Cr and Co was conducted in the south-west part of New Caledonia during the 20th century. Abandoned mining and prospecting sites were severely affected by erosion, resulting in an increase in the load of terrigenous particles transported to the coral reef lagoon. This article assesses the impact of a typical small catchment area (La Coulée River, 85 km2 watershed) on two...

Increasing evidence suggests that 5-HT(1A) receptor (5-HT(1A)R) is implicated in anxiety disorders. However, the mechanism underlying the role of 5-HT(1A)R in these diseases remains unknown. Here, we show that 5-HT(1A)R-selective agonist 8-OH-DPAT and selective serotonin reuptake inhibitor (SSRI) fluoxetine downregulated hippocampal neuronal nitric oxide synthase (nNOS) expression, whereas 5-HT...

OBJECTIVE To compare the antipyretic efficacy of an initial 30-mg/kg acetaminophen loading dose versus a 15-mg/kg maintenance dose. METHODS A double-blind, parallel-group, randomized clinical trial was conducted. A total of 121 febrile (rectal temperature between 39 degrees C and 40 degrees C) but otherwise healthy outpatients who were 4 months to 9 years of age and weighed 4 to 26 kg were as...

The current study included finding the concentrations of heavy elements (Co, Ni, Cu, As, Zn, Cd and Hg) in surface soil studying environmental effects Shwan Refinery within Kirkuk Governorate. Twenty samples were collected with a depth 0-20 cm. prepared laboratory sent to laboratories Geology Department at Faculty Engineering, Ankara University for purpose conducting chemical analyzes using Ind...

7-Nitroindazole (7-NI) inhibits neuronal nitric oxide synthase in vivo and reduces l-DOPA-induced dyskinesias in a rat model of parkinsonism. The aim of the present study was to determine if the anti-dyskinetic effect of 7-NI was subject to tolerance after repeated treatment and if this drug could interfere with the priming effect of l-DOPA. Adult male Wistar rats (200-250 g) with unilateral de...
