the purpose of the present study was to determine the acute toxicity (lc 50 ) of hgcl 2 and cuso 4 in caspian roach ( rutilus caspicus ) and cuso 4 in caspian kutum ( rutilus kutum ). the caspian roach lc 50 values for hgcl 2 at 24, 48, 72, and 96-hrs of exposure, were 0.64, 0.61, 0.42, and 0.28 mg l -1 , respectively, and for cuso 4 were 11.55, 5.08, 2.49, and 1.47 mg l -1 , respectively. the ...

27 The brain stem nucleus Locus Coeruleus (LC) is thought to modulate cortical excitability 28 by norepinephrine (NE) release in LC forebrain targets. The effects of LC burst 29 discharge, typically evoked by a strong excitatory input, on cortical ongoing activity are 30 poorly understood. To address this question, we combined direct electrical stimulation of 31 LC (LC-DES) with extracellular r...

The objective was to evaluate the effect of tannery sludge vermicompost in the chemical properties of soil cultivated with tomato and irrigated with wastewater. The experimental design was completely randomized in a factorial 6 × 2, totaling twelve treatments with three replications. The treatments were: four tannery sludge vermicompost (25% Sludge tannery(LC) + manure T1, 25% Sludge tannery(LC...

Introduction: Pain as a complex process in the CNS has been extensively studied by many researchers. It has been found that pain is controlled by certain pathways in the CNS, one of most important of which is the descending noradrenergic system. The pathway begins with Locus Coeruleus (LC) nucleus and ends in the spinal cord. In this study, formalin test was used as a chemical and tonic pain...

background: there are several plant extractions which are being used for mosquito control. the aim of this study was to evaluate the efficacy of olea vera, linum usitatissimum and piper nigera against anopheles stephensi and aedes aegypti under laboratory conditions. methods: these tests were carried out using who recommended bioassay method for adult mosquitoes. results: the extracts from blac...

introduction: it has been shown that orexin peptides have a role in opioid withdrawal behaviors. orexin-expressing neurons that are present in the hypothalamic nuclei send dense projections to the locus coeruleus (lc). withdrawal syndrome is temporally associated with hyperactivity of lc neurons. however, lc neurons do not show withdrawalinduced hyperactivity in the brain slices from morphine-d...

This investigation examined the molluscicidal and larvicidal activity of eight plants that are used in the traditional medicine of the Pankararé indigenous people in the Raso da Catarina region, Bahia state, Brazil. The tested plants were chosen based on the results of previous studies. Only those plants that were used either as insect repellents or to treat intestinal parasitic infections were...

Hepatic uptake of propionyl-L-carnitine (PLC) and L-carnitine (LC) was assessed with the impulse-response technique in the single-pass perfused rat liver. The experiments involved a rapid injection (impulse) of a mixture of the radiolabeled test compound (PLC or LC) and a reference compound (sucrose) into portal vein inflow and collection and radiochemical analysis (response) of the venous outf...

The applicability of GC, GC/MS and liquid chromatography with tandem mass spectrometry (LC/MS/MS) to screening for 140 pesticides in agricultural products was examined. Validation of multi-residue screening methods for the determination of 88 pesticides in 12 crops (asparagus, cauliflower, burdock, carrot, broccoli, spinach, matsutake mushroom, orange, soybean, sesame, millet and tea) was done ...
