Glucose lowering therapy in type 1 and type 2 diabetes is often associated with hypoglycemic events. To avoid this, glucose lowering therapies need to be developed that support the hypoglycemic defense mechanisms. Such development needs a tool for evaluating counterregulatory mechanisms in vivo. A sustained glucagon release during hypoglycemia is of most importance to hypoglycemic defense mechanis
The positron emission tomography (PET)/computed tomography (CT) camera is a combination of a PET camera and a CT. The image from the PET camera is based on the detection of radiation that is emitted from a radioactive tracer, which has been given to the patient as an intravenous injection. The radiation that is emitted from the radioactive tracer is more energetic than any other radiation used in
We have developed the novel Aerosol Dynamics, gas- and particle-phase chemistry model for laboratory CHAMber studies (ADCHAM). The model combines the detailed gas-phase Master Chemical Mechanism version 3.2 (MCMv3.2), an aerosol dynamics and particle-phase chemistry module (which considers acid-catalysed oligomerization, heterogeneous oxidation reactions in the particle phase and non-ideal interac
High-resolution spectral Doppler is an important and pow- erful non-invasive tool for estimation of velocities in blood vessels using medical ultrasound scanners. Such estimates are typically formed using an averaged periodogram technique, resulting in well-known limitations in the resulting spectral resolution. Recently, we have proposed tech- niques to instead form high-resolution data-adaptive
Phase change material (PCM) absorbs or releases latent heat when it changes phases, making thermal-regulated clothing possible. The objective of this study was to quantify the relationships between PCM cooling rate and temperature gradient, mass, and covering area on a thermal manikin in a climatic chamber. Three melting temperatures (24, 28, 32 °C) of the PCMs, different mass, covering areas, and
We demonstrate that grafted human fetal mesencephalic neurons can survive and extend axons for 22 years in the brain of a patient with Parkinson's disease (PD). In this patient, the overall survival and fiber outgrowth of the grafts were, however, relatively poor, which is consistent with the lack of significant clinical graft-induced benefit. We have compared the morphology of neurons in the 22-y
Exopolysaccharides (EPS) are excreted by microorganisms into the surrounding environment and have been shown to have various physiological effects and are commonly used as food additives due to their rheological properties. Four commercially available microbial EPS with different polymeric structures and composition were tested in LDL receptor knock-out mice to investigate their effect on blood ch
AIMS: Induction of iNOS in pancreatic islets leads to exaggerated NO production associated with dysfunctional β-cells. We examined insulin secretion, iNOS expression and its relation to the cAMP system in islets from human type 2 diabetes. METHODS: Insulin, glucagon and cAMP were analyzed by RIA; iNOS or PDE expression by qPCR, Western blot and confocal microscopy; cell viability by MTS. RESU
Purpose: To explore packaging in developing countries by means of identifying and describing supply chain needs regarding packaging. Design/methodology/approach: The research approach is qualitative and includes an embedded single case study of ambient milk supply chains in developing countries. Data collection is based on the review of internal company documents, semi-structured interviews with i
Bladder Exstrophy-Epispadias Complex (BEEC), the severe end of the uro-rectal malformation spectrum, has a profound impact on continence as well as sexual and renal functions. It is widely accepted that for the majority of cases the genetic basis appears to be multifactorial. Here, we report the first study which utilizes genome-wide association methods to analyze a cohort comprising patients pres
In Western blotting, immunodetection of housekeeping proteins is routinely performed to detect differences in electrophoresis loading. The present work describes a much faster and simpler protein staining method, which is compatible with ordinary blocking conditions. In addition, the method can be used after immunodetection with superior linearity compared to ordinary staining methods. After immun
Utilizing passive floodwater for spate irrigation in arid areas is an opportunity to use marginal water for production of crops. These techniques have only partially been studied in an extensive way. This paper describes a floodwater harvesting and spreading system for spate irrigation and field experiments for cultivation of barley. The field experiments were carried out during a three-year perio
MAX-lab is a Swedish national synchrotron radiation facility, first established as a small-scale university project in the late 1970s and then gradually developed into a national and international user facility. This article presents a historical study of MAX- lab that illustrates the decentralized character of the Swedish science policy system and especially its lack of aggregation mechanisms for
This clinical study was performed to investigate hand problems in individuals with systemic lupus erythematosus (SLE) in comparison with healthy controls, and to explore problems in the performance of daily activities related to these hand problems, in order to objectify findings from a previous mail survey. We also investigated whether a simple hand test could detect hand problems in SLE. All ind
This study investigated the ability of Zen meditators and non-meditators to sustain attention during an ongoing task. We hypothesized that meditators (n = 15) would sustain attention more efficiently than non-meditators (n = 19) by responding faster to task stimuli, making fewer commission errors, and reporting fewer interfering thoughts in the sustained attention to response task (SART). Their mo
Introduction and objective. Lead has a negative effect on the central nervous system (CNS), inter alia indicated by disturbance of posture. However, knowledge of the CNS effects at low exposure is insufficient. Individuals differ in vulnerability, possibly because of genetic predisposition. Polymorphisms in the δ-aminolevulinic acid dehydratase (ALAD) and vitamin D receptor (VDR) genes may modify
Environmental exposures, including smoking, hormone-related factors, and metabolic factors, have been implicated in the etiology of rheumatoid arthritis (RA). A previous study has indicated that blood lipid levels may influence the development of RA. The objective of this study was to investigate the impact of serum total cholesterol and triglycerides on the risk of RA in a prospective study.

We amplified RPB1, RPB2, and the ITS and LSU ribosomal genes from species mostly in the phlebioid clade, focusing heavily in phanerochaetoid taxa. We performed Maximum Likelihood and Bayesian analyses for different combinations of datasets. Our results provide a strongly supported phylogenetic picture of the phlebioid clade, representing 89 species in the four genes analyses, of which 49 represent
Background: Obesity has been proposed as a risk factor for pancreatic cancer. Methods: Pooled data were analyzed from the National Cancer Institute Pancreatic Cancer Cohort Consortium (PanScan) to study the association, between prediagnostic anthropometric measures and risk of pancreatic cancer. PanScan applied a nested case-control study design and included 2170 cases and 2209 control subjects. O
