Vitamin D deficiency as a risk factor for cystic fibrosis-related diabetes in the Scandinavian Cystic Fibrosis Nutritional Study

Aims/hypothesis Many cystic fibrosis patients are vitamin D-insufficient. Cystic fibrosis-related diabetes is a major complication of cystic fibrosis. The literature suggests that vitamin D might possess certain glucose-lowering properties. We aimed to assess the relationship between vitamin D and cystic fibrosis-related glucose intolerance. Methods We enrolled 898 cystic fibrosis patients from Sw

Values at stake: autonomy, responsibility, and trustworthiness in relation to genetic testing and personalized nutrition advice

Personalized nutrition has the potential to enhance individual health control. It could be seen as a means to strengthen people’s autonomy as they learn more about their personal health risks, and receive dietary advice accordingly. We examine in what sense personalized nutrition strengthens or weakens individual autonomy. The impact of personalized nutrition on autonomy is analyzed in relation to

The error structure of the Douglas-Rachford splitting method for stiff linear problems

The Lie splitting algorithm is frequently used when splitting stiff ODEs or, more generally, dissipative evolution equations. It is unconditionally stable and is con- sidered to be a robust choice of method in most settings. However, it possesses a rather unfavorable local error structure. This gives rise to order reductions if the evolution equation does not satisfy extra compatibility assumption

Effect of electroconvulsive seizures on pattern separation

Strategies employing different techniques to inhibit or stimulate neurogenesis have implicated a role for adult-born neurons in the therapeutic effect of antidepressant drugs, as well as a role in memory formation. Electroconvulsive seizures, an animal model of electroconvulsive therapy, robustly stimulate hippocampal neurogenesis but it is not known how this relates to either therapeutic efficacy

Metabolic gene variants associated with chromosomal aberrations in healthy humans.

Nonspecific chromosomal aberrations (CAs) are found in about 1% of lymphocytes drawn from healthy individuals. They include chromosome-type aberrations (CSAs), which are increased in exposure to ionizing radiation, and chromatid-type aberrations (CTAs) which in experimental systems are formed by DNA binding carcinogens and mutagens. The frequency of CAs is associated with the risk of cancer, but t

Molecular characterization and distribution of Haemoproteus minutus (Haemosporida, Haemoproteidae): A pathogenic avian parasite

Recently, the lineage hTURDUS2 of Haemoproteus minutus (Haemosporida, Haemoproteidae) was reported to cause mortality in captive parrots. This parasite lineage is widespread and prevalent in the blackbird Turdus merula throughout its entire distribution range. Species identity of other closely related lineages recently reported in dead parrots remains unclear, but will be important to determine fo

Low-level cadmium exposure and effects on kidney function.

The nephrotoxicity of cadmium at low levels of exposure, measured by urinary cadmium, has recently been questioned since co-excretion of cadmium and proteins may have causes other than cadmium toxicity. The aim of this study was to explore the relation between kidney function and low or moderate cadmium levels, measured directly in kidney biopsies.

Effects of ROCK inhibitor Y27632 and EGFR inhibitor PD168393 on human neural precursors co-cultured with rat auditory brainstem explant.

Hearing function lost by degeneration of inner ear spiral ganglion neurons (SGNs) in the auditory nervous system could potentially be compensated by cellular replacement using suitable donor cells. Donor cell-derived neuronal development with functional synaptic formation with auditory neurons of the cochlear nucleus (CN) in the brainstem is a prerequisite for a successful transplantation. Here a

A Randomized, Double-Blind, Phase III Study of the Immunogenicity and Safety of a 9-Valent Human Papillomavirus L1 Virus-Like Particle Vaccine (V503) Versus Gardasil®in 9-15-Year-Old Girls.

A 9-valent human papillomavirus (9vHPV) vaccine has been developedto prevent infections and diseases related to HPV 6/11/16/18 (as per the licensed quadrivalent HPV [qHPV] vaccine), as well as 5additional oncogenic HPV types (HPV 31/33/45/52/58). Compared with the qHPV vaccine, the 9vHPV vaccine potentially increases the coverage of protection from 70% to 90% of cervical cancers. We compared the i

Technological dynamics and social capability: US states and European nations

This article analyzes factors shaping technological capabilities in USA and European countries, and shows that the differences between the two continents in this respect are much smaller than commonly assumed. The analysis demonstrates a tendency toward convergence in technological capabilities for the sample as a whole between 1998 and 2008. The results indicate that social capabilities, such as

The ultrastructure of the striated muscles of Derocheilocaris typica (Mystacocarida, Crustacea).

The striated muscles of Derocheilocaris typica consist of mononucleated cells, each containing one filament bundle. Large muscles consist of two or more cells adjacent to each other. The mitochondria line up along the filament bundle on one side. The nucleus is situated in the mitochondrial row and has a small cytoplasmic area around it filled with glycogen. The sarcomeres are between 3 and 6 μm l

Immunohistochemistry in the differential diagnostics of primary lung cancer: an investigation within the southern Swedish lung cancer study.

Objectives: To assess immunohistochemical (IHC) stains differentially expressed between different types of lung cancer. Methods: We evaluated 16 different IHC stains in 209 prospectively included, surgically treated primary lung cancers, including 121 adenocarcinomas, 65 squamous cell carcinomas, 15 large-cell carcinomas, 5 adenosquamous carcinomas, 2 sarcomatoid carcinomas, and 1 small-cell carci

Resistin and Insulin/Insulin-like Growth Factor Signaling in Rheumatoid Arthritis

Objective. Human resistin has proinflammatory properties that activate NF-kappa B-dependent pathways, whereas its murine counterpart is associated with insulin resistance. The aim of this study was to examine potential cross-talk between resistin and insulin/insulin-like growth factor (IGF) signaling in rheumatoid arthritis (RA). Methods. Levels of IGF-1, IGF binding protein 3, and resistin were m

Solvation dynamics monitored by combined X-ray spectroscopies and scattering: photoinduced spin transition in aqueous [Fe(bpy)(3)](2+)

We have studied the photoinduced low spin (LS) to high spin (HS) conversion of aqueous Fe(bpy)(3) with pulse-limited time resolution. In a combined setup permitting simultaneous X-ray diffuse scattering (XDS) and spectroscopic measurements at a MHz repetition rate we have unraveled the interplay between intramolecular dynamics and the intermolecular caging solvent response with 100 ps time resolut

High-Dose Radioimmunotherapy Combined With Extracorporeal Depletion in a Syngeneic Rat Tumor Model

BACKGROUND: The aim of the current study was to investigate the possibility of increasing the maximal tolerated dose (MTD) of a tumor-selective radiolabeled antibody when radioimmunotherapy (RIT) is combined with extracorporeal depletion of radioimmunoconjugates from the circulation. Furthermore, the authors evaluated whether this increase in dose improved the therapeutic effect on solid manifest

Assessment of Peptide Chemical Modifications on the Development of an Accurate and Precise Multiplex Selected Reaction Monitoring Assay for Apolipoprotein E Isoforms

Apolipoprotein E (ApoE) is a polymorphic protein that plays a major role in lipid metabolism in the central nervous system and periphery. It has three common allelic isoforms, ApoE2, ApoE3 and ApoE4, that differ in only one or two amino acids. ApoE isoforms have been associated with the occurence and progression of several pathological conditions, such as coronary atherosclerosis and Alzheimer's d

In Situ X-ray Polymerization: From Swollen Lamellae to Polymer-Surfactant Complexes

The influence of the monomer diallyldimethylammonium chloride (D) on the lamellar liquid crystal formed by the anionic surfactant aerosol OT (AOT) and water is investigated, determining the lamellar spacings by SAXS and the quadrupolar splittings by deuterium NMR, as a function of the D or AOT concentrations. The cationic monomer D induces a destabilization of the AOT lamellar structure such that,

Rapid climate driven shifts in wintering distributions of three common waterbird species

Climate change is predicted to cause changes in species distributions and several studies report margin range shifts in some species. However, the reported changes rarely concern a species' entire distribution and are not always linked to climate change. Here, we demonstrate strong north-eastwards shifts in the centres of gravity of the entire wintering range of three common waterbird species alon

Systemic administration of Neuregulin-1ß(1) protects dopaminergic neurons in a mouse model of Parkinson's disease.

Neuregulin-1 (Nrg1) is genetically linked to schizophrenia, a disease caused by neurodevelopmental imbalance in dopaminergic function. The Nrg1 receptor ErbB4 is abundantly expressed on midbrain dopaminergic neurons. Nrg1 has been shown to penetrate blood-brain barrier, and peripherally administered Nrg1 activates ErbB4 and leads to a persistent hyperdopaminergic state in neonatal mice. These data
