The aim of the study was to evaluate the effect of rosiglitazone treatment on islet ghrelin and insulin gene expressions in streptozotocin (STZ)-induced diabetic rats. Animals were divided into four groups. 1. Intact controls. 2. Rosiglitazone-treated controls. 3. STZ-induced diabetes. 4. Rosiglitazone-treated diabetes, Rosiglitazone was given for 7 days at a dose of 20 mg/kg body weight. Ghrelin

The olivocerebellar and corticonuclear connections of the forelimb area of the paravermal medial C3 zone were studied in the cat using a combined electrophysiological and fluorescent tracer technique. During an initial operation under barbiturate anaesthesia, lobules IV/V of the cerebellar anterior lobe were exposed and small injections of dextran amines tagged with rhodamine or fluorescein were m

In a forest ecosystem at steady state, net carbon (C) assimilation by plants and C loss through soil and litter decomposition by heterotrophic organisms are balanced. However, a perturbation to the system, such as increased mean soil temperature, will lead to faster decay, enhancing CO2 release from decomposers, and thus upsetting the balance. Recent in situ experiments have indicated that the sti

An assessment of nutrient sustainability has been done for stands of European beech, Sycamore maple, European oak, Norway spruce, Larch, Grandis fir and Douglas fir at Bjornstorp Estate in southern Sweden. To estimate the nutrient sustainability, mass balance was calculated with respect to Ca, Mg, K, N and P. The release from mineral weathering was calculated using the PROFILE model. The leaching

Honeybees, like humans and most other vertebrates, are colour-blind in dim light. Bees are primarily day-active and have apposition compound eyes, the typical eye design of diurnal insects. Most bees are trichromats with photoreceptors sensitive in the UV, blue and green [1]. While their diurnal colour vision was established almost 100 years ago, honeybees are known to be colour-blind in moonlight

Background The relationship between selenium and cancer involves many different aspects. These include the forms of selenium present in the diet and in the body, their functions and mechanisms of action, and methods employed in assessing an individual's selenium nutritional status-both in general, and in epidemiological studies of the risk of cancer in relation to diet, as well as in connection wi

A system for interstitial photodynamic therapy is used in the treatment of thick skin tumors. The system allows simultaneous measurements of light fluence rate, sensitizer fluorescence, and tissue oxygen saturation by using the same fibers as for therapeutic light delivery. Results from ten tumor treatments using delta-aminolevulinic acid (ALA)-induced protoporphyrin IX show a significant, treatme

Nuclear magnetic resonance spectroscopy and rheological analysis have been used to investigate the stability of mechanically induced tri-ethylene-glycol-mono-n-decyl-ether (C10E3)/deuterium oxide (D2O) multi-lamellar vesicles (MLVs) and the transition from MLVs to planar lamellae. It was found that MLVs prepared by vortex stirring, relax back to the lamellar phase in a few hours while the relaxati

A major neuropathological feature of Parkinson's disease (PD) is the loss of nigrostriatal dopaminergic neuron. Patients exhibit motor symptoms, including bradykinesia, rigidity, and tremor. Neural grafting has been reported to restore striatial dopaminergic neurotransmission and induce symptomatic relief. The major limitation of cell replacement therapy for PD is the shortage of suitable donor ti

Objective: The aim of this study was to construct a rating scale to predict long-term outcome on the basis of clinical and sociodemographic characteristics in patients with symptoms of psychosis who seek psychiatric help for the first time. Method: Patients (N = 153) experiencing their first episode of psychosis (DSM-IV schizophrenia, schizophreniform disorder, schizoaffective disorder, brief psyc

Objective: To investigate the influence of social capital and individual factors on the level of leisure time physical inactivity in the neighbourhoods. Methods: The public health survey in Malm 1994 is a cross sectional study. A total of 5600 people aged 2080 years were invited to answer a postal questionnaire. The participation rate was 71. A multilevel logistic regression model, with individual

Severe caffeine poisoning is rare but associated with a high mortality. The symptoms are mainly attributable to hyperadrenergic stimulation, are relatively well known and described in the literature. Transient rises in plasma lactate levels may occur but are, however, less well described. We present a case of serious caffeine poisoning with a concomitant rise in lactate treated with a non-selectiv

We present a method for estimating the minimal periodic orbit structure, the topological entropy, and a fat representative of the homeomorphism associated with the existence of a finite collection of periodic orbits of an orientation-preserving homeomorphism of the disk D-2. The method focuses on the concept of fold and recurrent bogus transition and is more direct than existing techniques. In par

The properties of a sol-gel prepared Mn-modified TiO2 film have been studied with X-ray absorption spectroscopy (XAS) and photoelectron spectroscopy (PES) using synchrotron radiation. The chemical composition and oxidation state of the elements have been determined. The manganese content estimated by PES of the Mn-modified film is about 10% and both Mn2+ and Mn3+ are observed. Addition of Mn is fo

Objective: Body mass index (BMI) is associated with increased incidence of cardiovascular disease (CVD). However, the risk could be very different for individuals with the same body mass. The present study explored whether regional fat distribution, as measured by waist-hip ratio (WHR), could modify the impact of BMI on the risk of CVD in men and women. Design: Prospective population-based study.

Drug-induced dyskinesias (DID) manifested as hyperkinetic and/or dystonic movements or postures are common problems in Parkinson's disease (PD). Novel therapeutic interventions may offer possibilities to counteract these common adverse effects of an otherwise necessary treatment. To be able to evaluate the effects of such interventions on DID, reliable and relevant clinical assessment tools are ne

The early marsh orchid, Dactylorhiza incarnata (L.) Soo s. l., grows in medium-rich to rich fens and marshes over much of Europe and parts of Asia. The species is highly polymorphic and different forms may grow together at the same site. In the present study, I tested the hypothesis that these forms represent different migrant populations that have colonized Scandinavia independently of each other
