Risk factors for unnatural death : Fatal accidental intoxication, undetermined intent and suicide: Register follow-up in a criminal justice population with substance use problems

BACKGROUND: Risk factors for suicide and fatal accidental intoxication are extensively studied, while risk factors for intoxications/injuries of undetermined intent are less well known. The latter have shown an overlap with suicides, but also with fatal accidental intoxications. The objective was to analyze potential differences and similarities in the patterns of risk factors for accidental intox

Incretin hormone receptors are required for normal beta cell development and function in female mice

The incretin hormones, glucose dependent insulinotropic polypeptide (GIP) and glucagon-like peptide 1 (GLP-1), potentiate insulin secretion and are responsible for the majority of insulin secretion that occurs after a meal. They may also, however, have a fundamental role in pancreatic beta cell development and function, independently of their role in potentiating insulin secretion after a meal. Th

In vivo imaging of leukocyte-endothelium interactions in septic lung injury

Excessive accumulation of leukocytes in the lung represents a key feature in the development of an acute lung injury (ALI). Numerous studies demonstrated that leukocyte rolling is a compulsory precondition for the firm adhesion in organs. However, it seems that the recruitment process of leukocytes in the lung is more complex. Increasing evidence suggests that recruitment of leukocytes in pulmonar

How can rAAV-α-synuclein and the fibril α-synuclein models advance our understanding of Parkinson's disease?

Abstract: Animal models of Parkinson's disease (PD) are important for understanding the mechanisms of the disease and can contribute to developing and validating novel therapeutics. Ideally, these models should replicate the cardinal features of PD, such as progressive neurodegeneration of catecholaminergic neurons and motor defects. Many current PD models emphasize pathological forms of α-synucle

War Violence, Sexual War Violence and Victimhood in Reconciliation Narratives of Survivors from the War in Bosnia and Herzegovina

In this analysis of the retold experiences of 27 survivors of the war in northwestern Bosnia, the aim is to describe the informants’ portrayal of “war violence”, “sexual war violence”, “victimhood”, and “reconciliation” as a social phenomenon as well as analyzing the discursive patterns that contribute to constructing the category “victim” and “perpetrator”. The violence practice during the war is

Digital breast tomosynthesis (3D-mammography) screening : A pictorial review of screen-detected cancers and false recalls attributed to tomosynthesis in prospective screening trials

This pictorial review highlights cancers detected only at tomosynthesis screening and screens falsely recalled in the course of breast tomosynthesis screening, illustrating both true-positive (TP) and false-positive (FP) detection attributed to tomosynthesis. Images and descriptive data were used to characterise cases of screen-detection with tomosynthesis, sourced from prospective screening trial

Modeling of mass and charge transport in a solid oxide fuel cell anode structure by a 3D lattice Boltzmann approach

A 3D model at microscale by the lattice Boltzmann method (LBM) is proposed for part of an anode of a solid oxide fuel cell (SOFC) to analyze the interaction between the transport and reaction processes and structural parameters. The equations of charge, momentum, heat and mass transport are simulated in the model. The modeling geometry is created with randomly placed spheres to resemble the part o

SOFC modeling at the cell scale including hydrogen and carbon monoxide as electrochemically active fuels

Fuel cells are promising for future energy systems, because they are energy efficient and able to use renewable fuels. A fully coupled computational fluid dynamics (CFD) approach based on the finite element method (with the software COMSOL Multiphysics) in two-dimensions is developed to describe an intermediate temperature solid oxide fuel cell (SOFC) single cell. Governing equations covering heat

Aromatase inhibitors alone or sequentially combined with tamoxifen in postmenopausal early breast cancer compared with tamoxifen or placebo - Meta-analyses on efficacy and adverse events based on randomized clinical trials

Tamoxifen (TAM) and aromatase inhibitors (AI) are adjuvant therapy options for postmenopausal women with estrogen receptor positive (ER+) breast cancer. This systematic review of seven randomized controlled studies comparing TAM and AI, and one study comparing extended therapy with an AI with placebo after about 5 years of tamoxifen, aims to assess long-term clinical efficacy and adverse events. T

Interactive effects of physical fitness and body mass index on risk of stroke : A national cohort study

BACKGROUND: High body mass index (BMI) and low physical fitness are risk factors for stroke, but their interactive effects are unknown. Elucidation of interactions between these modifiable risk factors can help inform preventive interventions in susceptible subgroups.METHODS: National cohort study of all 1,547,294 military conscripts in Sweden during 1969-1997 (97-98% of all 18-year-old males). St

Neuropeptide Y (NPY) in cerebrospinal fluid from patients with Huntington's Disease : increased NPY levels and differential degradation of the NPY1-30 fragment

Huntington's disease (HD) is an inherited and fatal polyglutamine neurodegenerative disorder caused by an expansion of the CAG triplet repeat coding region within the HD gene. Progressive dysfunction and loss of striatal GABAergic medium spiny neurons (MSNs) may account for some of the characteristic symptoms in HD patients. Interestingly, in HD, MSNs expressing neuropeptide Y (NPY) are spared and

Marine silicon cycle through the Cenozoic

Omsättningen av kisel (Si) är en av de viktiga biogeokemiska processerna på jorden. Den lösta formen av Si (DSi) är ett nödvändigt näringsämne för såväl markens som havens ekosystem. Löst kisel kommer från den långsamma kemiska vittringen av kiselmineral. Denna process förbrukar koldioxid och bidrar därför till att reglera jordens klimat genom årmiljonerna. Kisel transporteras huvudsakligen via odSilicon (Si) cycle is one of Earth's major biogeochemical cycles. Furthermore, the dissolved form of Si (DSi) is an essential nutrient for both terrestrial and marine ecosystems. DSi ultimately derives from the slow process of chemical weathering of silicate minerals, a mechanism that consumes carbon dioxide, and therefore participates in regulating Earth's climate over geologic timescales. Si is

Identification of Non-HLA Genes Associated with Celiac Disease and Country-Specific Differences in a Large, International Pediatric Cohort

OBJECTIVES: There are significant geographical differences in the prevalence and incidence of celiac disease that cannot be explained by HLA alone. More than 40 loci outside of the HLA region have been associated with celiac disease. We investigated the roles of these non-HLA genes in the development of tissue transglutaminase autoantibodies (tTGA) and celiac disease in a large international prosp

Frequent mismatch-repair defects link prostate cancer to Lynch syndrome

BACKGROUND: A possible role for prostate cancer in Lynch syndrome has been debated based on observations of mismatch-repair defective tumors and reports of an increased risk of prostate cancer in mutation carriers. Potential inclusion of prostate cancer in the Lynch syndrome tumor spectrum is relevant for family classification, risk estimates and surveillance recommendations in mutation carriers.M

Tyrosine residues as redox cofactors in human hemoglobin : implications for engineering nontoxic blood substitutes

Respiratory proteins such as myoglobin and hemoglobin can, under oxidative conditions, form ferryl heme iron and protein-based free radicals. Ferryl myoglobin can safely be returned to the ferric oxidation state by electron donation from exogenous reductants via a mechanism that involves two distinct pathways. In addition to direct transfer between the electron donor and ferryl heme edge, there is
