Depressive Symptoms, Antidepressant Medication Use, and Insulin Resistance The PPP-Botnia Study

OBJECTIVE-Although insulin resistance (IR) may underlie associations between depressive symptoms and diabetes, previous findings have been contradictory. We examined whether depressive symptoms associate with IR and insulin secretion, and, additionally, whether antidepressant medication use may modulate such associations. RESEARCH DESIGN AND METHODS-A total of 4,419 individuals underwent an oral g

Hepatic contrast medium enhancement at computed tomography and its correlation with various body size measures

Background: When the same dose of iodine is given to all patients when performing abdominal computed tomography (CT) there may be a wide inter-individual variation in contrast medium (CM) enhancement of the liver. Purpose: To evaluate if any of the measures body height (BH), body mass index (BMI), lean body mass (LBM), ideal body weight (IBW), and body surface area (BSA) correlated better than bod

Computational assignment of redox states to Coulomb blockade diamonds

With the advent of molecular transistors, electrochemistry can now be studied at the single-molecule level. Experimentally, the redox chemistry of the molecule manifests itself as features in the observed Coulomb blockade diamonds. We present a simple theoretical method for explicit construction of the Coulomb blockade diamonds of a molecule. A combined quantum mechanical/molecular mechanical meth

Universal scaling of the elliptic flow data at RHIC

Recent PHOBOS measurements of the excitation function for the pseudo-rapidity dependence of the elliptic flow in Au + Au collisions at RHIC have posed a significant theoretical challenge. Here we show that these differential measurements, as well as the RHIC measurements on transverse momentum satisfy a universal scaling relation predicted by the Buda-Lund model, based on exact solutions of perfec

Dietary alpha-ketoglutarate reduces gastrectomy-evoked loss of calvaria and trabecular bone in female rats

Objective. Surgical removal of the stomach (gastrectomy, Gx) leads to osteopenia in animals and in humans. In the rat, Gx adversely affects calvaria and trabecular bone. alpha-Ketoglutarate (AKG) is a precursor of hydroxyproline - the most abundant amino acid in bone collagen. The purpose of this study was to investigate the effects of dietary AKG on Gx-induced osteopenia. Material and methods. Tw

Electrical wiring of live, metabolically enhanced Bacillus subtilis cells with flexible osmium-redox polymers.

The present study explores genetic engineering of the respiratory chain and the application of two different flexible osmium redox polymers to achieve efficient electric communication between the gram-positive organism Bacillus subtilis and an electrode. Poly(1-vinylimidazole)(12)-[Os-(4,4'-dimethyl-2,2'-bipyridyl)(2)Cl(2)](+/2+) (osmium redox polymer I) and poly(vinylpyridine)-[Os-(N,N'-methylate

Context Processing: A Distributed Approach

Context processing refers to the operation of processing different types of context data and/or information using different kinds of operators. These operators are applied according to some conditions or constraints given in context queries. Existing context aware systems process context data in a centralized fashion to answer context queries and generate context information. However, this method

N-acetyltransferase 2 Phenotype, Occupation, and Bladder Cancer Risk: Results from the EPIC Cohort

Background: An association between N-acetyltransferase 2 (NAT2) slow acetylation and bladder cancer has been consistently observed in epidemiologic studies. However, evidence has been mainly derived from case-control studies and was sparse from cohort studies. We evaluated the association between NAT2 slow acetylation and bladder cancer in a case-control study nested in the European Prospective In

Supporting positive mental health development in adolescents with a group cognitive intervention

Background: Supporting positive mental health development in adolescents is an important school health concern, but there is a need to investigate the suitability of the interventions used. Aim: To investigate the experiences of school health professionals in conducting a universal school-based program aimed at preventing depressive symptoms in adolescents. Methods: Twenty-two school health prof

A Hybrid Public Announcement Logic with Distributed Knowledge

In this paper the machinery of Hybrid Logic and the logic of public announcements are merged. In order to bring the two logics together properly the underlying hybrid logic has been changed such that nominals only partially denote states. The hybrid logic contains nominals, satisfaction operators, the downarrow binder as well as the global modality. Following this, an axiom system for the Hybrid P

FROM SERUM TO TISSUE: GALECTIN-BINDING GLYCOFORMS OF SERUM GLYCOPROTEINS AS FUNCTIONAL BIOMARKERS

Popular Abstract in Swedish Cellerna i kroppen är uppbyggda av fyra olika byggstenar: DNA, proteiner, fetter samt kolhydrater. Kolhydrater förknippas framförallt med energi och det pågår en intensiv debatt om kolhydraternas vara eller icke vara i vår kost. Kolhydraterna har dock också en helt annan funktion, en som är obestridligt oumbärlig för alla levande organismer. I denna roll förekommer de bGalectins are small soluble proteins defined by a conserved sequence motif that forms a defining β-galactoside binding site shared among galectins; adjacent binding sites give each galectin a unique fine specificity for a specific subset of galactose containing glycans. A wealth of data now suggests important roles of galectins in both cancer and inflammation. The aim of this project is to get a c

The clinical value of genetic analyses of bone and soft tissue tumors

Popular Abstract in Swedish Tumörer i ben och mjukdelar är vanliga men utgör endast 1 % av alla maligna neoplasier. De elakartade tumörerna är ofta utmanande att diagnostisera pga deras relativt likartade morfologi samt att de är ovanliga. Således är all tilläggsinformation värdefull och genetiska analysmetoder kan bidra med information som är användbar och i vissa fall tom avgörande för diagnostiTumors of bone and soft tissue are common but only constitute 1 % of all malignant tumors. The malignant tumors are often difficult to diagnose due to their rarity and morphological resemblance between subtypes. This makes the diagnostic process challenging. Thus, there is a need for ancillary techniques, such as genetic analyses, not only for diagnostic purposes, but also for obtaining informatio

Faceting and surface reconstruction of the GaP(111)B surface

Using Low Energy Electron Diffraction (LEED) and Scanning Tunneling Microscopy (STM) we have investigated the structure of the GaP(111)B surface. We have previously studied the formation of Ga droplets on GaP(111)B above the maximum temperature for congruent evaporation. In the present work, we investigate the nanometer-sized pyramid-shaped crystallites that are found on the GaP(111)B surface and

Competitive Semantic Memory Retrieval: Temporal Dynamics Revealed by Event-Related Potentials

Memories compete for retrieval when they are related to a common retrieval cue. Previous research has shown that retrieval of a target memory may lead to subsequent retrievalinduced forgetting (RIF) of currently irrelevant competing memories. In the present study, we investigated the time course of competitive semantic retrieval and examined the neurocognitive mechanisms underlying RIF. We contras

Architecture of the global land acquisition system: applying the tools of network science to identify key vulnerabilities

Global land acquisitions, often dubbed 'land grabbing' are increasingly becoming drivers of land change. We use the tools of network science to describe the connectivity of the global acquisition system. We find that 126 countries participate in this form of global land trade. Importers are concentrated in the Global North, the emerging economies of Asia, and the Middle East, while exporters are c

Senneolitisk grav i Uppåkra

Geophysical survey of the Iron Age settlement at Uppåkra church in southwestern Scania revealed some odd anomalies at the highest point of the study area. The anomalies showed a rectangle surrounded by a circle. Excavation uncovered a rectangular pit with drystone walls and a stone-paved floor, surrounded by an annular ditch with a diameter of eight metres. Looters had severely damaged this appare

Uncertainties in eddy covariance flux measurements assessed from CH4 and N2O observations

The uncertainty in eddy covariance (EC) flux measurements is assessed for CH4 and N2O using data measured at a dairy farm site in the Netherlands in 2006 and 2007. An overview is given of the contributing uncertainties and their magnitude. The relative and absolute uncertainty of a 30 min EC flux are estimated for CH4 and N2O using N = 2185 EC fluxes. The average absolute uncertainty and its stand

Intersexual differences in European lobster (Homarus gammarus): recognition mechanisms and agonistic behaviours

Dominance can be maintained through status recognition or recognition of individual (familiar) opponents. In crustaceans, both types of recognition exist, often based on chemical signals. Fight behaviours involved in establishment and maintenance of dominance relationships in male and female European lobster (Homarus gammarus) were examined. Same-sex pairs of size-matched animals interacted on two

Sustained reduction in major amputations in diabetic patients - 628 amputations in 461 patients in a defined population over a 20-year period

Background and purpose With an ageing population and an increasing incidence of diabetes, reduction of the number of diabetes-related amputations becomes increasingly difficult to achieve and maintain. There is controversy in this respect regarding the degree of success. We started a multidisciplinary treatment program for diabetic foot ulcers in 1982, and have now assessed incidence rates of ampu
