Reshaping commensal gut microbiota in early life with amoxicillin presents with lower blood pressure
Contributors: Saroj Chakraborty
... Pediatric hypertension is recognized as an emerging global health concern. While new guidelines are developed for facilitating clinical management, the reasons for the prevalence of hypertension in children remain unknown. Genetics and environmental factors do not fully account for the growing incidence of pediatric hypertension. Because stable bacterial flora in early life are linked with health outcomes later in life, we hypothesized that reshaping of gut microbiota in early developmental stages of life affects blood pressure (BP) of pediatric subjects. To test this hypothesis, we administered amoxicillin, the most commonly prescribed pediatric antibiotic, to alter gut microbiota of young, genetically hypertensive rats (study 1) and dams during gestation and lactation to reshape microbiota of offspring (study 2). Reshaping of microbiota, with reductions in Firmicutes/Bacteriodetes ratio observed in Amoxicillin treated young rats and in dams. Amoxicillin treated rats also had lower blood pressure compared to the untreated rats. In the young rats treated with amoxicillin, the lowering effect on blood pressure persisted even after the antibiotics were discontinued. Similarly, the offspring from the dams treated with amoxicillin also showed lower systolic blood pressure compared to the control rats. Remarkably, in all cases, a decrease in BP was associated with lowering of Veillonellaceae, which are succinate-producing bacteria. Elevated plasma succinate is reported in hypertension. Accordingly, serum succinate was measured and found lower in animals treated with amoxicillin. Our results demonstrate a direct correlation between succinate-producing gut microbiota and early development of hypertension, and indicate that reshaping gut microbiota, especially by depleting succinate-producing microbiota early in life may have long-term benefits for hypertension-prone individuals.

A new method for analyzing sustainability performance of global supply chains and its application to material resources
Contributors: Livia Cabernard, Stephan Pfister, Stefanie Hellweg
... VERSION 2 Compared to version 1, version 2 runs without matlab. The file “Instructions.pdf” attached below explains how to install and use this application. The file “Explanation_method_examples.pptx” attached below illustrates the principle of the method and how to use the application with several examples. OVERALL DESCRIPTION (same as for version 1): We share here the data compiled to calculate the results presented in the study «A new method for analyzing sustainability performance of global supply chains and its application to material resources». In order to allow for the compilation of all results of interest, we provide an application. This application is based on the multi-regional-input output database EXIOBASE3 (version 3.4) and data to assess the potential environmental impacts of emissions and resource use. While the data for assessing the environmental impacts is provided here, the user must download the Exiobase data from the Exiobase website (due to copyright issues). The provided application allows to assess the cumulated upstream impacts of any sector or region on the globe without double-counting and to track these impacts upstream and downstream the global value chain. The application covers a broad set of environmental and socio-economic indicators and the timespan from 1995 to 2011. The methodology of this application is comprehensively explained in the study: «A new method for analyzing sustainability performance of global supply chains and its application to material resources» (e.g Section 2.1 gives a broad overview of the principle of the method).

Virtual outcrop geology comes of age: the application of consumer-grade virtual reality hardware and software to digital outcrop data analysis
Contributors: Thomas Seers, Ali Sheharyar
... In this work, the need for discipline specific analysis tools is addressed by harnessing a consumer grade virtual reality system (HTC Vive) and freeform 3D visual arts software package (Google Tilt Brush) to interactively interpret and analyze sedimentary and structural architecture (bedding contacts, faults, fractures) from digital outcrop models. Having generated these interpretations, users utilize a script library developed in the MATLABTM language to extract geologically useful data (e.g. orientation, length, intensity) from interactively generated 3D mesh patches output by Tilt Brush. Note that the submission contains the MATLAB code library, test data and presentation (.ppt) with videoed examples of Tilt Brush data input and interpretation.

The NAD-booster nicotinamide riboside potently stimulates hematopoiesis through increased mitochondrial clearance
Contributors: Olaia Naveiras
... It has been recently shown that increased oxidative phosphorylation, as reflected by increased mitochondrial activity, together with impairment of the mitochondrial stress response can severely compromise hematopoietic stem cell (HSC) regeneration. Here we show that the NAD+-boosting agent Nicotinamide Riboside (NR) reduces mitochondrial activity within HSCs through increased mitochondrial clearance, leading to increased asymmetric HSC divisions. NR dietary supplementation results in a significantly enlarged pool of progenitors, without concurrent HSC exhaustion, improves survival by 80%, and accelerates blood recovery after murine lethal irradiation and limiting-HSC transplantation. In immune-deficient mice, NR increased the production of human leucocytes from hCD34+ progenitors. Our work demonstrates for the first time a positive effect of NAD+ boosting strategies on the most primitive blood stem cells, establishes a novel link between HSC mitochondrial stress, mitophagy and stem cell fate decision, and unveils the potential of NR to improve recovery of patients suffering from hematological failure including post-chemo/radiotherapy.
