Hyperprolactinemia has been suspected to increase mortality risk, but the available data are conflicting. The objective of this study was to estimate the association between hyperprolactinemia and all-cause and cardiovascular mortality among patients referred for assessment of prolactin. For this study, adults with no prio pituitary disease who underwent prolactin assessment at 3 university Hospitals in Denmark between 2001 and 2011 were included in a retrospective cohort study. A total of 3 633 patients with a median follow-up time of 5...

Background In the federal state of Saxony-Anhalt, gastric cancer (GC) incidence ranks among the highest in Germany. Helicobacter pylori prevalence is a surrogate marker for GC risk in a given population. In 2010 we reported an H. pylori seroprevalence of 44.4 % in patients at the emergency ward of the University Hospital of Magdeburg, the capital of Saxony-Anhalt. Our aim is to update these findings in a cohort of healthy blood donors from the same region. Materials and methods The sera of 516 consecutive blood donors (40...

BACKGROUND: Cardiac surgery may cause a serious coagulopathy leading to increased risk of bleeding and transfusion demands. Blood bank products are commonly first line haemostatic intervention, but has been associated with hazardous side effect. Coagulation factor concentrates may be a more efficient, predictable, and potentially a safer treatment, although prospective clinical trials are needed to further explore these hypotheses. This study investigated the haemostatic potential of ex vivo supplementation of coagulation factor concentrates versus blood bank products on blood samples drawn from patients undergoing cardiac surgery...

Gadolinium (Gd), a metal of the lanthanide series used in various industrial and medical purposes is released into the aquatic environment. However, there are few aquatic toxicological studies addressing environmental effects of Gd which remains unknown in aquatic animals. Therefore, this study aimed to compare the effects of GdCl3 and a gadolinium-based MRI contrast agent (Omniscan), in zebra mussels after 28 days through a multibiomarker approach. Data revealed that after GdCl3 exposure, the mRNA level of metallothionein (MT) was modulated, those of cytochrome c oxidase (CO1) and superoxide dismutase (SOD) were increased, while gene expressions of catalase (CAT) and glutathione-S-transferase (GST) were downregulated...

Importance: Following animal model data indicating the possible rejuvenating effects of blood from young donors, there have been at least 2 observational studies conducted with humans that have investigated whether donor age affects patient outcomes. Results, however, have been conflicting. Objective: To study the association of donor age and sex with survival of patients receiving transfusions. Design, Setting, and Participants: A retrospective cohort study based on the Scandinavian Donations and Transfusions database, with nationwide data, was conducted for all patients from Sweden and Denmark who received at least 1 red blood cell transfusion of autologous blood or blood from unknown donors between January 1, 2003, and December 31, 2012...

BACKGROUND: Detecting loss of resistance (LOR) can either be taught with dedicated simulators, with a cost ranging from &OV0556;1500 to 3000, or with the 'Greengrocer's Model', requiring simply a banana. OBJECTIVES: The purpose of this study was to compare three dedicated epidural puncture training simulators and a banana in their ability to simulate LOR. Our hypothesis was that there was a difference between the four simulators when comparing the detection of LOR...

The potential role of Eulemur fulvus (brown lemur) in the epidemiology of Rift Valley fever (RVF) in Mayotte, during an interepidemic period, was explored. In February and March 2016, 72 animals were blood sampled and tested for RVF. No evidence of RVF genome or antibodies was found in the samples. The role of other wild mammals on the island should, however, be further investigated.

Molecular doping of organic semiconductors is critical for optimizing a range of optoelectronic devices such as field-effect transistors, solar cells, and thermoelectric generators. However, many dopant:polymer pairs suffer from poor solubility in common organic solvents, which leads to a suboptimal solid-state nanostructure and hence low electrical conductivity. A further drawback is the poor thermal stability through sublimation of the dopant. The use of oligo ethylene glycol side chains is demonstrated to significantly improve the processability of the conjugated polymer p(g4 2T-T)-a polythiophene-in polar aprotic solvents, which facilitates coprocessing of dopant:polymer pairs from the same solution at room temperature...

The timing of puberty is a highly polygenic childhood trait that is epidemiologically associated with various adult diseases. Using 1000 Genomes Project-imputed genotype data in up to ∼370,000 women, we identify 389 independent signals (P < 5 × 10(-8)) for age at menarche, a milestone in female pubertal development. In Icelandic data, these signals explain ∼7.4% of the population variance in age at menarche, corresponding to ∼25% of the estimated heritability. We implicate ∼250 genes via coding variation or associated expression, demonstrating significant enrichment in neural tissues...

A specialized basal lamina (sBL) mediates adhesion of certain epithelial cells to the tooth. It is distinct because it does not contain collagens type IV and VII, is enriched in laminin-332, and includes three novel constituents called amelotin (AMTN), odontogenic ameloblast-associated (ODAM), and secretory calcium-binding phosphoprotein proline-glutamine rich 1 (SCPPPQ1). The objective of this study was to clarify the structural organization of the sBL. Fluorescence and immunogold labeling showed that the three proteins co-localize...

Solar cells made from inorganic-organic perovskites gradually approach market requirements as efficiency and stability improved tremendously in recent years. Planar low-temperature processed perovskite solar cells are advantageous for a possible large-scale production but are more prone to exhibit photocurrent hysteresis, especially in the regular n-i-p structure. Here, a systematic characterization of different electron selective contacts with a variety of chemical and electrical properties in planar n-i-p devices processed below 180 °C is presented...

Adolescent nutritional behaviors are assuming considerable importance in nutrition interventions given their important relationships with medium- and long-term outcomes. This is the period when young people undergo major anatomical and physiological maturational changes in preparation for adulthood. Nutritional requirements during puberty are higher during adolescence than during the prepubertal stage and during adulthood. A significant proportion of adolescents also become parents, and hence the importance of their health and nutritional status before as well as during pregnancy has its impact on their own health, fetal well-being, and newborn health...

The coupling of electron- and proton-transfer steps provides a general concept to control the driving force of redox reactions. N2 splitting of a molybdenum dinitrogen complex into nitrides coupled to a reaction with Brønsted acid is reported. Remarkably, our spectroscopic, kinetic, and computational mechanistic analysis attributes N-N bond cleavage to protonation in the periphery of an amide pincer ligands rather than the {Mo-N2 -Mo} core. The strong effect on electronic structure and ultimately the thermochemistry and kinetic barrier of N-N bond cleavage is an unusual case of a proton-coupled metal-to-ligand charge transfer process, highlighting the use of proton-responsive ligands for nitrogen fixation...

Filamentous organisms of the genus Streptomyces play an important role in industrial production processes, due to their extensive secondary metabolism variability, as well as their ability to secrete efficiently large amounts of (heterologous) proteins. While genetic engineering tools are available to rapidly build up large strain libraries, the subsequent strain screening and bioprocess development still constitutes a bottleneck. This is due to the lack of reliable parallelized and accelerated cultivation techniques for morphologically challenging organisms...

Alzheimer's disease (AD) is a progressively neurodegenerative disorder, which seriously affects human health but is still irreversible up to now. Recent studies indicate that type 2 diabetes mellitus (T2DM) is an important risk factor for AD, and the drugs used for treatment of T2DM have shown some neuroprotective effects in the treatment of AD. Glucagon-like peptide-1 (GLP-1)/ glucose-dependent insulinotropic polypeptide (GIP)/glucagon (Gcg) receptor Triagonist is a new monomeric polypeptide equally activating the GLP-1/GIP/Gcg receptors, which is built on the basis of GLP-1/Gcg receptor coagonist core sequence, and incorporated with partial amino acids of GIP...
