BACKGROUND AND PURPOSE: The aim was to determine whether a delayed transfer to an enriched environment improves outcome after focal brain ischemia. METHODS: Performance on a rotating pole, prehensile traction, limb placement, and postural reflexes were tested in 15 spontaneously hypertensive rats housed in standard laboratory cages for 2 weeks after middle cerebral artery ligation. Seven of the 15
Endocrine-disrupting compounds are exogenous agents that interfere with the natural hormones of the body. Human biological monitoring is a powerful method for monitoring exposure to endocrine disrupting compounds. In this review, we describe human biological monitoring systems for different groups of endocrine disrupting compounds, polychlorinated biphenyls, brominated flame retardants, phthalates
The use of supercritical CO, (SC-CO2) for extracting alkylresorcinols from rye bran was investigated. For pure SC-CO2, 35 MPa and 55 degrees C were used. SC-CO2 with 10% ethanol or methanol as co-solvents was tested at four pressure levels (8, 15, 30 and 35 MPa) and two temperatures (40 and 55 degrees C). Experiments were conducted at a constant SC-CO2 flow of 5 g/min for 2 h. For comparative purp
alpha(1)-Antitrypsin (alpha(1)-AT) is a serum protease inhibitor that is synthesized mainly in the liver, and its rate of synthesis markedly increases in response to inflammation. This increase in alpha(1)-AT synthesis results in an increase in peptides, like its carboxyl-terminal C-36 peptide (C-36), resulting from alpha(1)-AT cleavage by proteases. Atherosclerosis is a form of chronic inflammati
We examined the seasonal and inter-annual variation of leaf-level photosynthetic characteristics of three C-4 perennial species, Cyperus articulatus, Panicum repens and Imperata cylindrica, and their response to environmental variables, to determine comparative physiological responses of plants representing particular microhabitats within a seasonal tropical floodplain in the Okavango River Delta,
Rheumatoid arthritis (RA) is associated with certain MHC class II alleles and is characterized by a chronic autoimmune response in the joints. Using transgenic mice expressing human DR4 (DRB1*0401) and human CD4, but lacking endogenous MHC class II, we show that posttranslational glycosylation of type II collagen (CII) influences the level of T cell tolerance to this candidate cartilage-specific a
Persons who stutter often report their stuttering is influenced by emotional reactions, yet the nature of such relation is still unclear. Psychophysiological studies of stuttering have failed to find any major association between stuttering and the activity of the sympathetic nervous system. A review of published studies of heart rate in relation to stressful speech situations indicate that adults
Objective: To describe and compare self-reported health complaints, overall and health-related quality of life and to investigate how health complaints, age, gender, marital status, living and dwelling conditions and socio-economy predicted overall and health-related quality of life. Data and Method: A sample of 469 persons (aged 75-99) responded to a postal questionnaire. Multiple linear regressi
Atmospheric dispersion represents a relatively overlooked problem in connection with the ultimate quality of ELT images corrected by adaptive optics (AO). The aim of this paper is to evaluate the contribution from atmospheric dispersion to the background level of the point-spread function (PSF). Since proper suppression of this level is important for the prospects for direct exo-planet observation
The morphology of acute immune complex (IC) elicited synovitis in rabbit knee joints was studied, as well as IC-induced leukocyte activation in vivo and in vitro. Acute synovitis was induced by intra-articular injection of in vitro preformed, complement activating bovine serum albumin (BSA)-anti-BSA IC. Within 30 min, migration of polymorphonuclear granulocytes (PMNGs) was observed. Scanning elect
We report the isolation and characterization of a cDNA encoding the mitochondrial short chain DELTA-3,DELTA-2-enoyl-CoA isomerase from rat liver. Tryptic fragments of the purified protein were generated, purified, and sequenced. A rat liver cDNA library, constructed in the plasmid vector pUEX1 was screened with oligonucleotides synthesized on the basis of peptide sequences. The obtained clone cont
Background: The early diastolic downward slope (EDS) of the left atrioventricular plane displacement (AVPD) is a parameter of early left ventricular (LV) diastolic filling, particularly useful in revealing pseudonormalisation of the transmitral Doppler early to atrial (E/A) ratio. In recent studies LV early diastolic function seems to be closely linked to LV systolic function. In order to further
The aim of this work was to evaluate the measurement properties and hierarchical item structure of the Epworth Sleepiness Scale (ESS) in patients with Parkinson's disease (PD). Data were taken from a cross-sectional study regarding fatigue and sleep-related aspects of PD. One hundred and eighteen consecutive patients with neurologist-diagnosed PD without significant co-morbidities (54% men; mean a
1. We analysed time-series data from populations of red kangaroos (Macropus rufus, Desmarest) inhabiting four areas in the pastoral zone of South Australia. We formulated a set of a priori models to disentangle the relative effects of the covariates: rainfall, harvesting, intraspecific competition, and domestic herbivores, on kangaroo population-growth rate. 2. The statistical framework allowed fo
GPR30, or G protein-coupled estrogen receptor (GPER), is a GPCR reported to bind 17β-estradiol (E2), couple to the G proteins Gs and Gi/o, and mediate non-genomic estrogenic responses. However, controversies exist regarding the receptor pharmacological profile, effector coupling, and subcellular localization. We addressed the role of the type I PSD-95/Discs-large/ZO-1 homology (PDZ) motif at the r
