Cannabinoid receptor density and cannabinoid receptor-mediated G protein stimulation were studied by autoradiographic techniques throughout the budgerigar (Melopsittacus undulatus) brain. The maximal CB(1) receptor density value (using [(3)H]CP55,940 as radioligand) was found in the molecular layer of the cerebellum (Mol), and high binding values were observed in the nucleus taeniae amygdalae (...

The present study was carried out to detect the presence of Alfalfa mosaic alfamovirus (AMV), cucumber mosaic cucumovirus (CMV), lettuce mosaic potyvirus (LMV), cucumber green mottle mosaic virus (CGMMV), tomato bushy stunt tombusvirus (TBSV), tobacco mosaic tobamovirus (TMV), tomato black ring nepovirus (TBRV) and tomato mosaic tobamovirus (ToMV) in seeds of pepper, tomato, cucumber and lettuc...

Many existing training programs for Health Information Systems (HIS) do not adequately satisfy end users' needs nor meet training objectives. This is because they do not envisage the problems that users may encounter when performing specific tasks. Therefore the first priority for the development of an effective training program is to precisely assess the end users' training needs, a process ca...

Many studies have reported the occurrence of lethal acute renal failure after snakebites. The aim of the present investigation was to determine alterations in renal function produced by Crotalus durissus terrificus venom and crotoxin as well as the histological alterations induced by these venoms. Isolated kidneys from Wistar rats weighing 240 to 280 g were perfused with Krebs-Henseleit solutio...

Abstract Precipitation variability over the Tibetan Plateau (TP) depends largely on atmospheric circulation pattern associated with remote oceanic forcing, while contribution of sea surface temperature anomalies (SSTAs) in different ocean basins, especially tropical North Atlantic (TNA), remains unclear. By using multisource data and general model, this study reveals individual combined effects...

Fifty-nine percent of unselected strains of Haemophilus parainfluenzae were found to carry small, phenotypically cryptic plasmid DNA species. Using filter blot hybridization, we found several plasmids which were homologous to the small beta-lactamase-specifying plasmids pJB1 and pFA7, which were originally isolated from Haemophilus ducreyi and Neisseria gonorrhoeae, respectively. Detailed filte...

[1] Concentrations of heme b, the iron-containing component of b-type hemoproteins, ranged from< 0.4 to 5.3 pM with an average of 1.18 ± 0.8 pM (± 1σ; n= 86) in the Iceland Basin (IB), from< 0.4 to 19.1 pM with an average of 2.24 ± 1.67 pM (n = 269) in the tropical northeast Atlantic (TNA) and from 0.6 to 21 pM with an average of 5.1 ± 4.8 pM (n= 34) in the Scotia Sea (SS). Heme b concentration...
