Encouraging primary care research: evaluation of a one-year, doctoral clinical epidemiology research course.

Research and PhDs are relatively rare in family medicine and primary care. To promote research, regular one-year research courses for primary care professionals with a focus on clinical epidemiology were started. This study explores the academic outcomes of the first four cohorts of research courses and surveys the participants' perspectives on the research course. An electronic survey was sent to

Synthesis, structural and theoretical studies of a rare hexameric water cluster held in the lattice of {[Zn(HL)(phen)(H2O)]center dot 3(H2O)}2 (H3L = trans-aconitic acid)

The reaction of Zn(NO3)(2)center dot 3(H2O) with trans-aconitic acid (H3L), in presence of chelating 1,10-phenanthroline, leads to the formation of a dinuclear unit {[Zn(HL)(phen)(H2O)]center dot 3(H2O)}(2). The lattice water molecules are assembled as a centrosymmetric hexamer. The crystal structure, thermal studies, theoretical calculations, and the factors that stabilize this water hexamer are

Evaluation of recurrent venous thromboembolism in patients with Factor V Leiden mutation in heterozygous form.

INTRODUCTION: To evaluate the risk for recurrence after first venous thromboembolism (VTE) among patients with or without Factor V Leiden (FVL) mutation. MATERIALS AND METHODS: A prospective population based study of 1465 consecutive unselected VTE patients was performed at Skåne University Hospital 1998-2008. The VTE was objectively verified and the patients answered questionnaire and left bloo

The inflammatory mediator leukotriene D4 induces subcellular β-catenin translocation and migration of colon cancer cells.

The abnormal activation of the Wnt/β-catenin pathway frequently occurs in colorectal cancer. The nuclear translocation of β-catenin activates the transcription of target genes that promote cell proliferation, survival, and invasion. The pro-inflammatory mediator leukotriene D4 (LTD4) exerts its effects through the CysLT1 receptor. We previously reported an upregulation of CysLT1R in patients with

Structure and function of the C-terminal domain of MrpA in the Bacillus subtilis Mrp-antiporter complex - The evolutionary progenitor of the long horizontal helix in complex I.

MrpA and MrpD are homologous to NuoL, NuoM and NuoN in complex I over the first 14 transmembrane helices. In this work, the C-terminal domain of MrpA, outside this conserved area, was investigated. The transmembrane orientation was found to correspond to that of NuoJ in complex I. We have previously demonstrated that the subunit NuoK is homologous to MrpC. The function of the MrpA C-terminus was t

A Parameterization of Sticking Efficiency for Collisions of Snow and Graupel with Ice Crystals: Theory and Comparison with Observations

A new parameterization of sticking efficiency for aggregation of ice crystals onto snow and graupel is presented. This parameter plays a crucial role for the formation of ice precipitation and for electrification processes. The parameterization is intended to be used in atmospheric models simulating the aggregation of ice particles in glaciated clouds. It should improve the ability to forecast sno

Search for direct chargino production in anomaly-mediated supersymmetry breaking models based on a disappearing-track signature in pp collisions at root s=7 TeV with the ATLAS detector

A search for direct chargino production in anomaly-mediated supersymmetry breaking scenarios is performed in p p collisions at root s = 7 TeV using 4.7 fb(-1) of data collected with the ATLAS experiment at the LHC. In these models, the lightest chargino is predicted to have a lifetime long enough to be detected in the tracking detectors of collider experiments. This analysis explores such models b

The impact of ethnicity on glucose homeostasis after gestational diabetes mellitus.

The objective of this study was to examine measures of insulin resistance and beta cell function in relation to ethnicity and the development of diabetes after gestational diabetes mellitus (GDM). Glucose homeostasis was assessed during a 75 g oral glucose tolerance test 1-2 years after delivery in 456 women with previous GDM (362 European, 94 non-European; including 41 Arab and 43 Asian women) an

Coulomb Excitation of 104Sn and the Strength of the 100Sn Shell Closure

A measurement of the reduced transition probability for the excitation of the ground state to the first 2(+) state in Sn-104 has been performed using relativistic Coulomb excitation at GSI. Sn-104 is the lightest isotope in the Sn chain for which this quantity has been measured. The result is a key point in the discussion of the evolution of nuclear structure in the proximity of the doubly magic n

Context-dependent effects of yolk androgens on nestling growth and immune function in a multi-brooded passerine.

Female birds may adjust their offspring phenotype to the specific requirements of the environment by differential allocation of physiologically active substances into yolks, such as androgens. Yolk androgens have been shown to boost embryonic development, growth rate and competitive ability of nestlings, but they can also entail immunological costs. The balance between costs and benefits of androg

No evidence for shedding of circulating tumor cells to the peripheral venous blood as a result of mammographic breast compression.

This pilot study aimed to investigate whether mammographic compression procedures might cause shedding of tumor cells into the circulatory system as reflected by circulating tumor cell (CTC) count in peripheral venous blood samples. From March to October 2012, 24 subjects with strong suspicion of breast malignancy were included in the study. Peripheral blood samples were acquired before and after

Pharmacokinetic modeling of enterohepatic circulation of mycophenolic acid in renal transplant recipients.

Several factors contribute to mycophenolic acid (MPA) between-patient variability. Here we characterize the metabolic pathways of MPA and quantify the effect of combining genetic polymorphism of multidrug-resistant-associated protein-2, demographics, biochemical covariates, co-medication (cyclosporine (CsA) vs. macrolides), and renal function on MPA, 7-O-MPA-glucuronide (MPAG), and acyl-glucuronid

Molecular characterization of Haemoproteus sacharovi (Haemosporida, Haemoproteidae), a common parasite of columbiform birds, with remarks on classification of haemoproteids of doves and pigeons

Haemoproteus (Haemosporida, Haemoproteidae) is the largest genus of avian haemosporidian parasites, some species of which cause lethal diseases in birds. Subgenera Parahaemoproteus and Haemoproteus are usually accepted in this genus; these parasites are transmitted by biting midges (Ceratopogonidae) and hippoboscid flies (Hippoboscidae), respectively. As of yet, species of Parahaemoproteus have no

Mucosal glucagon-like peptide-1 and gastric inhibitory polypeptide cell numbers in the super-obese human foregut after gastric bypass.

Super-obesity, a body mass index>50 kg/m(2), is difficult to treat. Many studies have focused on the anatomic changes of the intestines; the physiologic background is not clearly identified. It is established that Roux-en-Y gastric bypass (RYGB) augments secretion of glucagon-like peptide-1 (GLP-1), peptide tyrosine tyrosine (PYY), and insulin, but other aspects of gut hormone cell function in the

Mosaic variation in allozyme and plastid DNA markers in the European ranges of Silene vulgaris and its partially sympatric relative S-uniflora (Caryophyllaceae)

The perennial herbs Silene vulgaris and S. uniflora are closely related, partially sympatric and interfertile, yet morphologically distinct. We used nuclear (allozyme) and plastid (polymerase chain reaction-restriction fragment length polymorphism) DNA markers to investigate whether these species have a shared history of postglacial colonization and hybridization in Europe, as inferred from large-

Genotype–phenotype correlations in THAP1 dystonia: Molecular foundations and description of new cases

An extensive variety of THAP1 sequence variants have been associated with focal, segmental and generalized dystonia with age of onset ranging from 3 to over 60 years. In previous work, we screened 1114 subjects with mainly adult-onset primary dystonia (Neurology 2010; 74:229-238) and identified 6 missense mutations in THAP1. For this report, we screened 750 additional subjects for mutations in cod

Evidence for caste differences in anal droplet alarm pheromone production and responses in the eusocial thrips Kladothrips intermedius

Thrips (Thysanoptera) are tiny insects that produce anal secretions whenthreatened. Several studies have shown that, depending on the species,the droplets may contain alarm pheromones and/or repellents againstenemies. In the eusocial gall-inducing thrips Kladothrips intermedius bothlarvae and adults produce such droplets. There are two castes of adults inthis species, soldiers (the sub-fertile and

Solvent-free lipase-mediated synthesis of six-membered cyclic carbonates from trimethylolpropane and dialkyl carbonates

Six-membered cyclic carbonates with hydroxyl and/or alkoxycarbonyloxy groups, as potential monomers for polyurethanes and polycarbonates, were prepared by the reaction between trimethylolpropane (TMP) with dimethyl carbonate (DMC) or diethylcarbonate (DEC) mediated by immobilized Candida antarctica lipase B, NovozymR (R) 435 in a solvent-free medium. The dialkyl carbonate served as a solvent for t

Near-surface silica does not increase radiative heat dissipation from plant leaves

It has been suggested that plants are able to increase radiative heat dissipation from their leaves by depositing near-surface silica, in this way increasing emissivity of infrared radiation and lowering leaf temperature. In order to test this theory, we have compared emissivity and radiative dissipation over the mid-infrared range 2.5–22.3 lm of leaves of plants that accumulate silica and plants
