Several brain-imaging studies have found associations between aberrant functioning in the frontal and temporal lobes and violent offending. We have previously reported decreased frontotemporal perfusion unrelated to psychosis, substance abuse, or current medication in 21 violent offenders. In the present study, we compared the regional cerebral blood flow (rCBF) in a new group of 32 violent offend
Major practical constraints on neural grafting in Parkinson's disease are the shortage of human donor tissue and the great loss of dopamine neurons during the grafting procedure. The vast majority of implanted embryonic dopamine neurons are believed to die within a few days of transplantation surgery, at least in part through apoptosis. We have previously found that survival of nigral grafts in ro
SETTING: Addis Ababa Tuberculosis Demonstration and Training Center, Ethiopia. OBJECTIVES: To determine the pattern of drug resistance among re-treatment cases of pulmonary tuberculosis (TB), to determine the risk factors associated with multi-drug resistant (MDR) TB, and to propose re-treatment regimens based on the patterns of susceptibility to first-line and alternative drugs. DESIGN: One hundr
Caldicellulosiruptor saccharolyticus is an extremely thermophilic, gram-positive anaerobe which ferments cellulose-, hemicellulose- and pectin-containing biomass to acetate, CO2, and hydrogen. Its broad substrate range, high hydrogen-producing capacity, and ability to coutilize glucose and xylose make this bacterium an attractive candidate for microbial bioenergy production. Here, the complete gen
Sixteen open-top chambers (diameter, 3.66 m) were established in a scrub oak habitat in central Florida where vegetation was removed in a planned burn prior to chamber installation. Eight control chambers have been continuously exposed to ambient air and eight have been continuously exposed to elevated CO2 at twice-ambient concentration (similar to700 ppm) for 5 years. Soil cores were collected fr
OBJECTIVE: To investigate the leptin and TNF systems in relation to testosterone in insulin resistant myotonic dystrophy (DM1) subjects. DESIGN AND SUBJECTS: Fasting morning samples and diurnal sampling during 24 h. Forty-two DM1 subjects (20 women and 22 men; age 41.5 (28.5-58.7)y, body mass index (BMI) 23.3 (18.6-29.2)kg/m(2); median and 10th and 90th percentile, respectively). Fifty healthy vol
The effect of Phytophthora species, soil chemistry, precipitation and temperature on the vitality of oak was evaluated in 32 oak stands in southern Sweden. In addition, the relationship between the occurrence of Phytophthora species and soil conditions was determined. The results showed that there was a weak association between the presence of P. quercina, the most frequently recovered Phytophthor
Background: No recommendation exists on the amount of petrolatum (pet.) preparation to be applied in a Finn Chamber (R) or van der Bend Chamber. Objectives: The aim of this study was to determine the appropriate amount of pet. preparation to apply in the Finn and van der Bend chambers. Methods: 12 volunteers were patch tested with green-coloured pet. in Finn and van der Bend chambers on the back o
A series of copolymers of N-isopropylacrylamide (NIPAM) and the more hydrophobic comonomer N-tert-butylacrylamide (NTBAM), with increasing NTBAM content (i.e., increasing hydrophobicity) were prepared. The adhesion of human epithelial cells on polymer films prepared from copolymers of NIPAM: NTBAM was observed to increase with increasing polymer hydrophobicity. However, in the absence of serum, ce
Using a population synthesis model we estimate the fraction of stars of different types that are likely to show eclipses, as a function of the period. The population model is based on the bse-code from Hurley et al. (2002) which is a rapid binary evolution code that include all common effects in close binaries such as mass transfer, tidal locking, wind etc. We use this to evolve millions of system
Background— Inflammation is an important pathophysiological feature of abdominal aortic aneurysms (AAA). Whether elevated levels of inflammation-sensitive plasma proteins (ISPs) predict the long-term risk of fatal or repaired AAA is largely unknown. Methods and Results— Five ISPs (fibrinogen, orosomucoid, {alpha}1-antitrypsin, haptoglobin, and ceruloplasmin) were measured in 6075 healthy men, mea
A gas chromatographic method was developed to quantify the phytotoxin prehelminthosporol, which is a sesquiterpene metabolite of the plant pathogen Bipolaris sorokiniana. The toxin was extracted from mycelium or culture filtrates, pre-cleaned using solid phase extraction, and analyzed by gas chromatography as a trimethylsilyl-derivative. The detection limit of the method was 5 ng mul(-)1 (signal t
Purpose - The main purpose is to provide an in-depth understanding of market orientation in retailing and to identify the specific activities that have to be understood and managed in order for a retail firm to become market oriented. Design/methodology/approach - Qualitative studies of six firms in Sweden, Italy and the UK were carried out, including in-depth interviews with retail managers and m
A subpopulation of neurones in the cerebellar nuclei projects to the inferior olive, the source of the climbing fibre input to the cerebellum. This nucleo-olivary projection follows the zonal and, probably also, the microzonal arrangement of the cerebellum so that closed loops are formed between the neurones in the olive, the cerebellar cortex and the nuclei. The nucleo-olivary pathway is GABAergi
A feasibility study and two interlaboratory exercises on the determination of selected heterocyclic amines (HAs) in beef extract, organised in the framework of a European project, are presented. The aim of these exercises was to improve the quality of the laboratories and to evaluate the performance of a standardised analytical method and also the methods currently used by each of the participants
