BACKGROUND The demand for total hip and total knee arthroplasties is increasing as are the waiting times for these procedures. Because of the differences between rural and urban areas in terms of the provision of arthroplasty services and between the 2 patient groups, patient perspectives of waiting times may also be different. METHODS To compare waiting times for initial orthopedic consultat...

In Table 1 below, we explore the distribution of health spending for a given population. Here we array the population in deciles, from deciles of individuals with the lowest health spending per capita to deciles of individuals with the highest per-capita health spending. These deciles are shown on the leftmost column of Table 1. Individuals in the 9 and 10 deciles represent the presumably sicke...

Studies describing the chemical composition of fine aerosol (PM2.5) in urban areas are often conducted for a few weeks only and at one sole site, giving thus a narrow view of their temporal and spatial characteristics. This paper presents a one-year (11 September 2009–10 September 2010) survey of the daily chemical composition of PM2.5 in the region of Paris, which is the second most populated ...

Anandamide is an endogenous ligand for brain cannabinoid CB1 receptors, but its behavioral effects are difficult to measure due to rapid inactivation. Here we used a drug-discrimination procedure to test the hypothesis that anandamide, given i.v. or i.p., would produce discriminative effects like those of -9-tetrahydrocannabinol (THC) in rats when its metabolic inactivation was inhibited. We al...

Background: Dayak Onion (Eleutherine bulbosa Urb.) is a typical plant of Kalimantan which traditionally used by the community as medicinal plant. onion bulbs have been proven had many pharmacology activities. Objective: This study aims to determine nonspesific and specific parameters 70% ethanol extract Eleutherine Urb. Total flavonoids was also quantified Methods:. Urb extracted with maseratio...

BACKGROUND The endogenous cannabinoid system plays an important role in motivation, stress, and drug abuse. Pharmacologically, the endocannabinoid system can be stimulated by either agonists of CB1 receptors or inhibition of metabolic degradation of endogenous cannabinoids and consequent increases in their brain levels. METHODS Here, we investigated whether chronic administration during a per...

Whereas the inhibition of fatty acid amide hydrolase (FAAH) or monoacylglycerol lipase (MAGL), the respective major hydrolytic enzymes of N-arachidonoyl ethanolamine (AEA) and 2-arachidonoylglycerol (2-AG), elicits no or partial substitution for Δ(9)-tetrahydrocannabinol (THC) in drug-discrimination procedures, combined inhibition of both enzymes fully substitutes for THC, as well as produces a...

BACKGROUND AND PURPOSE Cannabinoid receptor agonists reduce intestinal propulsion in rodents through the CB(1) receptor. In addition to its antagonistic activity at this receptor, rimonabant (N-(piperidino)-5-(4-chlorophenyl)-1-(2,4-dichlorophenyl)-4-methyl-3-pyrazole-carboxyamide) alone augments intestinal transit. Using rat and guinea-pig ileum MPLM (myenteric plexus-longitudinal muscle) prep...

Screens in mosaicDrosophila tissues that use chemical mutagenesis have identified many regulators of growth and patterning. Many of the mutant phenotypes observed were contingent upon the presence of both wild-type and mutant cells in the same tissue. More recently, large collections of RNAi lines or cDNAs expressed under Gal4/UAS control have been used to alter gene expression uniformly in spe...

The present study investigated whether peroxynitrite (ONOO)-elicited cytotoxicity on human brain vessel smooth muscle cells (HBVSMCs) was related to alteration in programmed cell death 4 (PDCD4) gene expression. Cell viability, morphological changes and apoptosis were determined by methylthiazoletetrazolium (MTT) assay, acridine orange staining and flow cytometry, respectively. Expressions of P...
