(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 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)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 ...
-
(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)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 ...
-
(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)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)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)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)Study and objectives: (Na + K)-adenosine triphosphatase (ATPase) activity, oxidative stress parameters, and morphologic characteristics of the lung and kidney of rats under acute ethanol intoxication were assessed to ...
-
(2002)Cytochrome P450-dependent oxidation of lauric acid, p-nitrophenol and ethanol by liver microsomal fractions were studied in control rats and in animals given either ethanol, red wine, or alcohol-free red wine for 10 weeks. ...
-
(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. ...
-
(Lippincott Williams and Wilkins, 2002)Synovium and synovial fluid findings in SAPHO (synovitis, acne, pustulosis, hyperostosis, and osteitis) syndrome have not been well characterized, and only a few patients have been described in the Americas. We describe ...
-
(2002)Clinical and research practices designed by developed countries are often implemented in host nations of the Third World. In recent years, a number of papers have presented a diversity of arguments to justify these practices ...
-
(2002)We presented a rare case of large tracheal hamartoma in a 14-year-old boy and its management with a novel technique of reparation with pericardium of entire membranous portion of the trachea, after the failure of more ...
-
(Lippincott Williams and Wilkins, 2002)The objective of this study was to evaluate the prevalence of antibodies to Helicobacter pylori CagA and VacA proteins and correlate this prevalence with gastric diseases in colonised Chileans. The study was performed in ...
-
Hematological parameters and stress index in Rufous-collared Sparrows dwelling in urban environments (American Ornithologist Society, 2002)A number of wild bird species have fortuitously incorporated themselves into urban life. One of these, the Rufous-collared Sparrow (Zonotrichia capensis), dwells with seemingly similar success in urban and rural areas. ...
-
(2002)Medicine is becoming increasingly confident that scientific advances, especially in the area of genetics, will allow a major improvement in the control and eradication of disease. This development seems to go hand in hand ...
