In summary, we report that CD38+ NK cells may be an unexplored therapeutic target for priming the immune system of MM patients.Analysis of observed Indian Summer Monsoon precipitation reveals more increase in extreme precipitation (in terms of its magnitude) over south India compared to north and central India during 1971-2017 (base period 1930-1970). In the future, analysis of precipitation from the Coordinated Regional Downscaling Experiment indicates a southward shift of precipitation extremes over South Asia. For instance, the Arabian Sea, south India, Myanmar, Thailand, and Malaysia are expected to have the maximum increase (~18.5 mm/day for RCP8.5 scenario) in mean extreme precipitation (average precipitation for the days with more than 99th percentile of daily precipitation). However, north and central India and Tibetan Plateau show relatively less increase (~2.7 mm/day for RCP8.5 scenario). Analysis of air temperature at 850 mb and precipitable water (RCP4.5 and RCP8.5) indicates an intensification of Indian Ocean Dipole in future, which will enhance the monsoon throughout India. Moisture flux and convergence analysis (at 850 mb) show a future change of the direction of south-west monsoon winds towards the east over the Indian Ocean. These changes will intensify the observed contrast in extreme precipitation between south and north India, and cause more extreme precipitation events in the countries like Myanmar, Thailand, Malaysia, etc.BACKGROUND/OBJECTIVES Sarcopenia defined by the association of skeletal muscle mass depletion and a decreased physical performance is underdiagnosed in chronic obstructive pulmonary disease (COPD) patients. The objective was to assess prevalence of sarcopenia and malnutrition in hospitalized COPD patients during an acute exacerbation, after 6 months follow-up and the 1-year survival. SUBJECTS/METHODS Hospitalized COPD patients were recruited for the assessment of body composition, handgrip strength, respiratory function, and maximal inspiratory and expiratory pressures (MIP and MEP), during hospitalization and 6 months later. gp91dstat Sarcopenia was defined according to the criteria of the European Working Group on Sarcopenia in Older Adults, malnutrition was defined according to French criteria 2007. Survival data were collected 12 months after hospitalization. RESULTS We analyzed data from 54 patients, aged 68 ± 9 years and BMI 26.9 ± 7.8 kg/m2, with an average FEV1 of 1.13 ± 0.49 l (45 ± 16% predicted value). Sarcopenia and malnutrition prevalence were, respectively, 48% and 52% during hospitalization, 30% and 30% after 6 months. MIP and MEP were lower in sarcopenic patients (p = 0.01 and 0.009, respectively). In multivariate analysis, skeletal muscle mass index and MIP were positively correlated at 6 months' follow-up (r = 0.40, p = 0.04). The 1-year survival rate was lower in sarcopenic patients (65 vs 86%, p = 0.03), particularly when malnutrition was associated (p = 0.02). CONCLUSIONS Sarcopenia in COPD patients is highly prevalent during and after recovery of an acute exacerbation, exposing to lower survival. A multimodal management is required to treat sarcopenia and improve prognosis.The prognostic significance of sarcopenia has been widely studied in different cancer patients. This study aimed to analyze the influence of sarcopenia on long-term survival in patients with colorectal liver metastasis (CRLM) undergoing hepatic resection. A retrospective analysis of 182 patients undergoing hepatic resection for CRLM was performed. Sarcopenia was determinedusing the Hounsfield unit average calculation (HUAC), a measure of muscle quality-muscledensity at preoperative abdominal computed tomography scans. Sarcopenia was defined as an HUAC score of less than 22 HU calculated using receiver operating characteristic analysis. The prognostic relevance of clinical variables and overall survival (OS) and recurrence-free survival (RFS) was evaluated. Patients with sarcopenia were older (p 3) (HR 1.750; 95% CI, 1.066-2.872; p = 0.027), high aspartate aminotransferase level (HR 1.024; 95% CI, 1.003-1.046; p = 0.025) and male gender (HR 1.688; 95% CI, 1.036-2.748; p = 0.035) were independent factors of RFS. In conclusion, despite no significance in whole cohort, sarcopenia was predictive of worse OS in patients with multiple CRLM after partial hepatectomy.Under the same selection pressures, two genetically divergent populations may evolve in parallel toward the same adaptive solutions. Here, we hypothesized that magnetotaxis (i.e., magnetically guided chemotaxis) represents a key adaptation to micro-oxic habitats in aquatic sediments and that its parallel evolution homogenized the phenotypes of two evolutionary divergent clusters of freshwater spirilla. All magnetotactic bacteria affiliated to the Magnetospirillum genus (Alphaproteobacteria class) biomineralize the same magnetic particle chains and share highly similar physiological and ultrastructural features. We looked for the processes that could have contributed at shaping such an evolutionary pattern by reconciling species and gene trees using newly sequenced genomes of Magnetospirillum related bacteria. We showed that repeated horizontal gene transfers and homologous recombination of entire operons contributed to the parallel evolution of magnetotaxis. We propose that such processes could represent a more parsimonious and rapid solution for adaptation compared with independent and repeated de novo mutations, especially in the case of traits as complex as magnetotaxis involving tens of interacting proteins. Besides strengthening the idea about the importance of such a function in micro-oxic habitats, these results reinforce previous observations in experimental evolution suggesting that gene flow could alleviate clonal interference and speed up adaptation under some circumstances.An amendment to this paper has been published and can be accessed via a link at the top of the paper.The structure of the bacteriome associated with grapevine roots can affect plant development, health and grape quality. We previously investigated the bacterial biodiversity of the Vitis vinifera cv. Pinot Noir rhizosphere in a vineyard subjected to integrated pest management. The aim of this work is to characterize the bacteriome of V. vinifera cv. Pinot Noir in a conventionally managed vineyard using a metabarcoding approach. Comparisons between the microbial community structure in bulk soil and rhizosphere (variable space) were performed and shifts of bacteriome according to two sampling times (variable time) were characterized. Bacterial biodiversity was higher at the second than at the first sampling and did not differ according to the variable space. Actinobacteria was the dominant class, with Gaiella as the most represented genus in all the samples. Among Proteobacteria, the most represented classes were Alpha, Beta and Gamma-Proteobacteria, with higher abundance at the second than at the first sampling time.
