Saccharomyces cerevisiae expresses α-glucoside transporters, such as MalX1p (X=1(Agt1p), 2, 3, 4, and 6), which are proton symporters. These transporters are regulated at transcriptional and posttranslational levels in the presence of glucose. Malt wort contains glucose, maltose, and maltotriose, and the assimilation of maltose is delayed as a function of glucose concentration. With the objective of increasing beer fermentation rates, we characterized α-glucoside transporters and bred laboratory yeasts that expressed various α-glucoside transporters for the simultaneous uptake of different sugars...

BACKGROUND: We sought to externally validate our pathologic nodal staging score (pNSS) model, which allows for quantification of the likelihood that a pathologically node-negative patient will not have lymph node (LN) metastasis after radical prostatectomy for prostate cancer (PCa) in a population-based cohort. PATIENTS AND METHODS: We analyzed data from 50,598 patients treated with radical prostatectomy and pelvic LN dissection using the Surveillance, Epidemiology, and End Results database...

One of the most common marine dinophytes is a species known as Heterocapsa triquetra. When Stein introduced the taxon Heterocapsa he formally based the type species H. triquetra on the basionym Glenodinium triquetrum. The latter was described by Ehrenberg and is most likely a species of Kryptoperidinium. In addition to that currently unresolved nomenclatural situation, the thecal plate composition of H. triquetra sensu Stein (1883) was controversial in the past. In order to clarify the debate, we collected material and established the strain UTKG7 from the Baltic Sea off Kiel (Germany, the same locality as Stein had studied), which was investigated using light and electron microscopy, and whose systematic position was inferred using molecular phylogenetics...

Robots intended for social contexts are often designed with explicit humanlike attributes in order to facilitate their reception by (and communication with) people. However, observation of an "uncanny valley"-a phenomenon in which highly humanlike entities provoke aversion in human observers-has lead some to caution against this practice. Both of these contrasting perspectives on the anthropomorphic design of social robots find some support in empirical investigations to date. Yet, owing to outstanding empirical limitations and theoretical disputes, the uncanny valley and its implications for human-robot interaction remains poorly understood...

Helicobacter suis colonizes the stomachs of a variety of animals, including humans, and is more likely than other Helicobacter species to induce gastric mucosa-associated lymphoid tissue lymphoma. Obesity is a low-grade chronic inflammatory state in which the induction of a chemokine network contributes to a variety of diseases. However, the effect of obesity on the development of gastric MALT in the presence of H. suis infection remains unclear. Here, we reveal that high-fat-diet-induced obesity upregulates the expression of lymphoid chemokines in the stomach and accelerates the H...

The aging population increases the demand of intensive care unit (ICU) treatments. However, the availability of ICU beds is limited. Thus, ICU admission of octogenarians is considered controversial. The population above 80 years is a very heterogeneous group though, and age alone might not be the best predictor. Aim of this study was to analyze resource consumption and outcome of octogenarians admitted to a medical ICU to identify reliable survival predictors in a senescent society.This retrospective observational study analyzes 930 octogenarians and 5732 younger patients admitted to a medical ICU...

A 53-year-old man had a diagnosis of mucosa-associated lymphoid tissue lymphomas of the dura in the left tentorium. The patient underwent whole-body F-FDG PET/CT and C-methionine PET/CT in order to complete the staging of dural mucosa-associated lymphoid tissue lymphoma. C-methionine uptake was detected in multiple meningeal sites, including left tentorium, with no significant FDG uptake in the same regions.

Gluten free products have emerged during the last decades, as a result of a growing public concern and technological advancements allowing gluten reduction in food products. One approach is to use gluten degrading enzymes, typically at low or ambient temperatures, whereas many food production processes occur at elevated temperature. We present in this paper, the discovery, cloning and characterisation of a novel recombinant thermostable gluten degrading enzyme, a proline specific prolyl endoprotease (PEP) from Sphaerobacter thermophiles...

Background Magnetic resonance imaging (MRI) is widely used in several muscle disorders. Diffusion-weighted imaging (DWI) is an imaging modality, which can reflect microstructural tissue composition. The apparent diffusion coefficient (ADC) is used to quantify the random motion of water molecules in tissue. Purpose To investigate ADC values in patients with myositis and non-inflammatory myopathy and to analyze possible associations between ADC and laboratory parameters in these patients. Material and Methods Overall, 17 patients with several myositis entities, eight patients with non-inflammatory myopathies, and nine patients without muscle disorder as a control group were included in the study (mean age = 55...

A 64-years-old woman with chronic thyroiditis was refered to our hospital because of anterior mediastinum tumors identified by chest computed tomography (CT). The lesions with increased fluoro-2-deoxy-D-glucose (FDG) uptake was noted by CT and positron emission tomography (PET). Extended thymo-thymectomy was performed, and the tumors was completely resected. Pathologically, the tumors were diagnosed as mucosa-associated lymphoid tissue( MALT) lymphoma of the thymus. Postoperative chemotherapy was not performed and the patient has been well for 4 years without recurrence...

Associations between immunoglobulin (IG) receptors with distinctive immunogenetic features and particular gene mutations is a recurring theme in mature B cell lymphomas. Relevant observations have been made in chronic lymphocytic leukemia (CLL), where gene mutations are distributed asymmetrically in cases bearing or not somatic hypermutations within the clonotypic immunoglobulin heavy chain variable region (IGHV) genes (e.g. TP53 mutations predominate in IG-unmutated CLL, whereas the opposite is seen for MYD88 mutations, enriched in IG-mutated CLL) and in subsets of cases with stereotyped IG (enrichment for SF3B1 mutations in CLL subset #2)...

In a retrospective study performed in California, U.S.A., ca. 3% of patients with gastric intestinal metaplasia (GIM) developed gastric cancer (GC) within a median time period of 4.6 years after diagnosis of GIM. This observation stresses the importance of targeted surveillance even in regions with a low GC prevalence. Patients with alcoholic liver disease as well as survivors of colorectal and lobular breast cancer were found to be at increased risk of secondary GC. A population-based Chinese study confirmed "serologic biopsy" as a useful screening tool for stratifying the individual risk of developing GC...

Based on our previous demonstration of CXCR7 as the major mediator of CXCL12 signaling in cultured astrocytes, we have now compared astrocytic expression of the CXCL12 receptors, CXCR7 and CXCR4, during CNS development and disease. In addition, we asked whether disease-associated conditions/factors affect expression of CXCL12 receptors in astrocytes. In the late embryonic rat brain, CXCR7(+)/GFAP(+) cells were restricted to the ventricular/subventricular zone while CXCR4 was widely absent from GFAP-positive cells...
