The predominant menaquinones of strain LAM7117T were MK-8 and MK-9. Based on the phenotypic characteristics, chemotaxonomic data and genotypic analyses, strain LAM7117T should be classified as a novel species of genus Arthrobacter, for which the name Arthrobacter sulfonylureivorans sp. nov. is proposed. The type strain is LAM7117T (= JCM 32824T = CGMCC 1.16681T).Ever since the development of the first antibiotic compound with anticancer potential, researchers focused on isolation and characterization of prospective microbial natural products with potential anti-infective and anticancer activities. The present work describes the production of bioactive metabolites by heterotrophic bacteria associated with intertidal seaweeds with potential anti-infective and anticancer activities. The bacteria were isolated in a culture-dependent method and were identified as Shewanella algae MTCC 12715 (KX272635) and Bacillus amyloliquefaciens MTCC 12716 (KX272634) based on combined phenotypic and genotypic methods. Further, the bacteria were screened for their ability to inhibit drug-resistant infectious pathogens and prevent cell proliferation of human liver carcinoma (HepG2) and breast cancer (MCF7) cell lines, without affecting the normal cells. Significant anti-infective activity was observed with bacterial cells and their organic extracts against broad-spectrum multidrug-resistant pathogens, such as vancomycin-resistant Enterococcus faecalis, methicillin-resistant Staphylococcus aureus, Klebsiella pneumonia and Pseudomonas aeruginosa with minimum inhibitory concentration ≤ 3.0 µg mL-1 as compared to the antibiotic agents' chloramphenicol and ampicillin, which were active at ≥ 6.25 mg mL-1. The extracts also exhibited anticancer activity in a dose-responsive pattern against HepG2 (with IC50, half maximal inhibitory concentration ~ 78-83 µg mL-1) and MCF7 (IC50 ~ 45-48 µg mL-1) on tetrazolium bromide screening assay with lesser cytotoxic effects on normal fibroblast (L929) cell lines (IC50 > 100 µg mL-1). The results revealed that seaweed-associated heterotrophic bacteria could occupy a predominant role for a paradigm shift towards the development of prospective anti-infective and anticancer agents.Association of rhizobia with other plant growth-promoting bacteria (PGPB), such as Azospirillum, have the potential to increase crop yields. This work aimed to assess how Rhizobium tropici and Azospirillum brasilense alone or in combination, affect the growth and yields of common bean grains (Phaseolus vulgaris L.). In a field experiment, R. tropici and A. brasilense were inoculated on seeds, alone or in combination, associated or not with foliar spraying of A. brasilense. Shoot biomass, nitrogen accumulation, thousand-grain weight, and grain yield were evaluated. Application of A. brasilense, on seed or by foliar spraying, and seed inoculation of R. tropici, had an additive effect, increasing biomass and accumulated nitrogen, thousand-grain weight, and grain yield.Secreted frizzled-related proteins (SFRP) are glycoproteins containing a so-called frizzled-like cysteine-rich domain. This domain enables them to bind to Wnt ligands or frizzled (FzD) receptors, making potent regulators of Wnt signaling. As Wnt signaling is often altered in cancer, it is not surprising that Wnt regulators such as SFRP proteins are often differentially expressed in the tumor microenvironment, both in a metastatic and non-metastatic setting. Indeed, SFRP2 is shown to be specifically upregulated in the tumor vasculature of several types of cancer. Several studies investigated the functional role of SFRP2 in the tumor vasculature, showing that SFRP2 binds to FzD receptors on the surface of tumor endothelial cells. This activates downstream Wnt signaling and which is, thereby, stimulating angiogenesis. Interestingly, not the well-known canonical Wnt signaling pathway, but the noncanonical Wnt/Ca2+ pathway seems to be a key player in this event. In tumor models, the pro-angiogenic effect of SFRP2 could be counteracted by antibodies targeting SFRP2, without the occurrence of toxicity. Since tumor angiogenesis is an important process in tumorigenesis and metastasis formation, specific tumor endothelial markers such as SFRP2 show great promise as targets for anti-cancer therapies. This review discusses the role of SFRP2 in noncanonical Wnt signaling and tumor angiogenesis, and highlights its potential as anti-angiogenic therapeutic target in cancer.Post-transplant cyclophosphamide (PTCY) effectively prevents graft-versus-host disease after unmanipulated HLA-haploidentical HSCT. The use of PTCY in the unrelated donor HSCT setting is less explored. We conducted a retrospective study of 132 consecutive patients undergoing a matched or 9/10 mismatched unrelated donor HSCT in 4 centers in Spain, 60 with anti-thymocyte globulin (ATG)-based prophylaxis combined with MTX-CsA, and 72 using a PTCY-based regimen. Peripheral blood stem cells were used as graft in most patients (111 patients, 84%); mMUD donors were balanced between groups. Cumulative incidences of grades II-IV and III-IV acute GVHD at 100 days were lower in the PTCy group (46% vs. 67%, p = 0.008; 3% vs. 34%, p = 0.003), without statistically significant differences in the 2-year cumulative incidence of chronic moderate-severe GVHD. At 2 years, no significant differences were observed in overall survival, event-free survival, cumulative incidence of relapse, and non-relapse mortality. GVHD was the most frequent cause of NRM in the ATG group. No differences were observed between groups in the composite endpoint of GVHD-free and relapse-free survival. In this study, PTCy combined with additional immunosuppression after MUD/mMUD HSCT showed a reduction of aGVHD rate with safety results comparable to those obtained with the ATG-based prophylaxis.25-hydroxy vitamin D [25-(OH)D] is widely used to determine vitamin D status in clinic. The aim of our study was to evaluate the prognostic value of 25-(OH)D in extranodal NK/T cell lymphoma (ENKTL). Ninety-three (93) ENKTL patients with available serum 25-(OH)D values were enrolled in our study. Vitamin D deficiency is defined as a 25-(OH)D below 50 nmol/L (20 ng/ml). Univariate and multivariate regression analyses were performed to determine independent risk factors for progression-free survival (PFS) and overall survival (OS). Receiver operator characteristic (ROC) curves were plotted, and corresponding areas under the curves (AUC) were calculated to estimate the accuracy of PINK-E (prognostic index of natural killer lymphoma added with Epstein-Barr virus-DNA status) and 25-(OH)D deficiency in ENKTL risk-stratification. Our results suggested that the vitamin D deficiency was an independent inferior prognostic factor for both PFS [hazard ratio (HR), 2.869; 95% confidence interval (CI), 1.540 to 5.346; P = 0.003] and OS (HR, 3.204; 95% CI, 1.559 to 6.583; P = 0.006) in patients with ENKTL. Additionally, we demonstrated that adding 25-(OH)D deficiency to PINK-E score system indeed has a superior prognostic significance than PINK-E alone for PFS [AUC 0.796 (95% CI 0.699 to 0.872) vs. 0.759 (95% CI 0.659 to 0.841), P = 0.020] and OS [AUC 0.755 (95% CI 0.655 to 0.838) vs. 0.721 (95% CI 0.618 to 0.809), P = 0.040]. In conclusion, our study proved that 25-(OH)D deficiency was associated with inferior survival outcome of ENKTL patients.Timely administration of appropriate empirical antibiotics in febrile neutropenia is crucial for favourable patient outcomes. There are guidelines in place recommending such antibiotics. However, regional variations and local epidemiological data must be evaluated to tailor the antibiotics for best possible and rational use. In this study, we audited the clinical and microbiological data of febrile neutropenic episodes occurring at a tertiary care haematology institution. Three hundred and ninety-three febrile neutropenic episodes occurring in 123 patients over a 1-year period were analysed for microbial profile, sensitivity and resistance patterns, and finally clinical outcomes. Gram-negative bacilli (GNB) blood stream infections (46.9%) were more prevalent as compared to gram-positive infections (41.9%). Overall mortality due to complicated neutropenic sepsis was 19.5% (24/123 patients). Increased resistance to carbapenems, beta-lactam beta-lactamase inhibitor combinations, aminoglycosides, fluoroquinolones, and cephalosporins were observed. Cefepime and tigecycline resistance were seen in 20% and 15% GNB isolates, respectively. Chest was the most frequent focus of infection, and acute myeloid leukaemia (AML) was the most common underlying disorder which correlated with the likelihood of death (p less then 0.01). Multidrug-resistant GNB (esp. TMP195 Klebsiella sp.) are still most worrisome isolates in neutropenic patients. Single-agent cefepime or piperacillin-tazobactam/tigecycline combination may be considered empirical agents. Chest infections and AML were independent predictors of poor clinical outcome in neutropenic patients. Regular audit of infections and antibiotic susceptibility data is needed to improve clinical outcomes in patients with febrile neutropenia.In a metaphor such as lawyers are sharks, the concept lawyers, which is the metaphor topic, and the concept sharks, which is the metaphor vehicle, interact to produce a figurative meaning such that lawyers are predatory. Some theorists argue that sensorimotor properties of the vehicle are the basis of metaphor comprehension. Accordingly, the metaphor lawyers are sharks is processed as a simulation in which bodily actions related to sharks are accessed (e.g., sharks chasing prey). In contrast, the long-standing assumption is that metaphors are processed as abstractions with no role played by sensorimotor properties. From this theoretical perspective, abstract characteristics of sharks (e.g., vicious, predatory) are argued to be the core properties involved in metaphor processing. Here, we juxtapose these two opposing views of metaphor processing using cross-modal lexical priming. We find evidence that low-familiar metaphors (e.g., highways are snakes) prime bodily-action associates (i.e., slither) but not abstraction associates (i.e., danger), and are hence processed via simulation, whereas high-familiar metaphors (e.g., lawyers are sharks) prime abstraction associates (i.e., killer) but not bodily-action associates (i.e., bite) and are therefore processed via abstraction. The results align with views of cognition and language that posit the presence of both embodied and abstract representations.

The inclusion of transitional care professionals to improve the sectoral interface management is politically supported. The nine components of the transitional care model (TCM) originating from the USA, are used in arandomized controlled trial within the TIGER project, which is funded by the Federal Joint Committee of Germany. Geriatric patients are accompanied prior to discharge from hospital and up to 12months after discharge in the home environment.

Within the framework of the TIGER project a nationwide survey was carried out on the use of the TCM components in the accompanied transition from hospital to home in the field of geriatrics.

Adata collection was set up to establish contact with people from the immediate and care policy environment of geriatrics. In a2-stage process, the first question was whether ageriatric project was known that focuses on the transition from hospital to home in geriatric patients. After confirmation, aquestionnaire could be filled out online or by post.

Atotal of 31 different projects out of 39 answered questionnaires were identified.
