(Society of Biology of Chile, 2002)Necrosis is considered as a non-specific form of cell death that induces tissue inflammation and is preceded by cell swelling. This increase in cell volume has been ascribed mainly to defective outward pumping of Na+ caused ...
-
(2002)Paralytic shellfish toxins (PSTs) are sodium channel blocking (SCB) toxins, produced by cyanobacteria, as well as by marine dinoflagellates and their associated bacteria, and cause serious health and economic concern ...
-
(Oxford University Press, 2002)Quantitative MRI and phosphorus magnetic resonance spectroscopy (31P-MRS) were used to investigate skeletal muscle metabolism in vivo in patients with dermatomyositis (DM) and polymyositis (PM) in order to evaluate the ...
-
(Lippincott Williams and Wilkins, 2001)The effects of systemically and intrathecally administered ketamine on spinal wind-up of normal and monoarthritic rats were studied by using C-fiber reflex responses evoked by repetitive (0.6Hz) electric stimulation. Both ...
-
(American Psychiatric Association, 2002)Objective: Some genome-wide scans and association studies for schizophrenia susceptibility genes have yielded significant positive findings, but there is disagreement between studies on their locations, and no mutation has ...
-
(Elsevier, 2002)Objectives. To examine, by way of histologic examination, the destruction of excised prostate glands treated with thermal ablation. Thermal ablation treatment with permanently implanted temperature selfregulating rods ...
-
(2002)Trypanosoma cruzi CRK3 gene encodes a Cdc2p related protein kinase (CRK). To establish if it has a role in the regulation of the parasite cell cycle we studied CRK3 expression and activity throughout three life cycle stages. ...
-
(2002)Although the action of Gonyautoxins (GTXs) and Saxitoxin (STX) mechanisms is well known at the molecular level, there are still many unresolved questions associated with the intoxication syndrome in mammals. For example, ...
-
(2002)Previous studies have shown that the HPV-1 6 E7 protein interacts with TBP. This interaction was found to take place through residues in the carboxy terminal half of E7, mutation of which resulted in weaker transforming ...
-
(2002)We have previously found the existence of a relation between activity of the brain mitochondrial aldehyde dehydrogenase (ALDH2) and consumption of ethanol in rats of the low-alcohol-drinking (UChA) and the high-alcohol-drinking ...
-
(2002)The association of hypertension and coronary heart disease is a frequent one. There are several pathophysiologic mechanisms which link both diseases. Hypertension induces endothelial dysfunction, exacerbates the atherosclerotic ...
-
(2002)We report the establishment of continuously growing cell lines from spinal cords of normal and trisomy 16 fetal mice. We show that both cell lines, named M4b (derived from a normal animal) and MTh (trisomic) possess ...
-
(2002)By proteomic analysis we found a 21-kDa protein (P21) from Acidithiobacillus ferrooxidans ATCC 19859 whose synthesis was greatly increased by growth of the bacteria in pyrite, thiosulfate, elemental sulfur, CuS, and ZnS ...
-
(2001)Desipramine-induced inhibition of spinal cord nociceptive transmission was studied in rats with or without lesion of the bulbospinal noradrenergic system by recording the C-fiber evoked nociceptive reflex from a hind limb. ...
-
(2002)The aim of this study was to develop a rat model of capsaicin-induced pain in the orofacial region. We examined the effects of subcutaneous injection of different doses of capsaicin (0.25, 0.4, 0.8, 1.5, 2.5, 25, 50, 100, ...
-
(2002)The present study was designed to assess the effect of okadaic acid (OA), a protein phosphatase inhibitor, on aldosterone secretion in response to angiotensin II (AII), adrenocorticotropin (ACTH) and rises in external ...
-
(2002)Intracerebral manganese administration together with the DT-diaphorase inhibitor dicoumarol (Mn3+ 40 nmol+-dicoumarol 2 nmol; in 4 μl) into the left medial forebrain bundle (MFB) produced a behavioural pattern characterised ...
-
(2002)The intracellular polymerization of cytoskeletal proteins into their supramolecular assemblies raises many questions regarding the regulatory patterns that control this process. Binding experiments using the ELISA solid ...
-
(2002)SNpc neurons are uniquely at risk from damage by a variety of ROS, including catechol-quinones formed from autoxidation of DA; as well as Tyr O, TyrOOH, H2O2O-.2, NO., HONOO-, and HO.. The high content of Fe2+ in SNpc ...
-
(2002)We have previously reported on a defect in both extracellular signal-regulated protein kinase (ERK) and c-jun N-terminal kinase (JNK) mitogen-activated protein kinase (MAPK) activation in splenocytes obtained from old rats. ...
