... Our study aimed to investigate the protective effect confered by immune priming in A. vulgare against S. enterica by determining its setting up and duration. We also analysed haemocyte variations in order to linked them with a potential protection against the bacterial infection. For these purposes, we conducted two distinct experiments with several independant experimental replicates: The first consisted to primed (i.e "vaccinated") individuals either with a low dose of living S. enterica bacteria, with LB broth or without injection (control). 1 day , 7 days or 15 days later, we sampled haemolymph of individuals and examined haemocyte concentrations and viabilities. Data of these experiments are available in the file "Prigot_DataHaemocytes" in the open access repository Mendeley Data. The second experiment was based on the same priming treatment than in the first (with low dose of living bacteria, LB broth or nothing). But 1 day, 7 days or 15 days later, we injected a LD50 of bacteria in all individuals and monitored their survival rates for 7 days. Datas of these experiments are available in the file "Prigot_DataSurvivals" in the open access repository Mendeley Data. Differents animals were use for the two experiments. You can also find enclosed a .txt file (Prigot_DataLegends) giving all legends of the datasets colomn heads. Datasets are ready to be used in R program for statistical analysis, see enclosed the R-script file. For any problems in the dataset comprehension, do not hesitate to contact us.

... A portfolio of commodity index-ETF pairs was constructed and its performance was compared against the Bloomberg commodity index. The portfolio was trained on data from 2011 to 2014 to determine the optimal parameters for trade-execution thresholds. Using these parameters and the optimal exposures found from optimizing the risk-adjusted expected returns, the trading strategy was tested from 2015 to 2018 with the portfolio rebalanced at the beginning of each year. Comparing the returns of the portfolio against the Bloomberg Barclays Commodities Index as a benchmark, it was found that the portfolio outperformed the benchmark in total returns and Sharpe ratio for 2015, 2017, and 2018, but it underperformed for both metrics in 2016. Performing a paired t-test on the portfolio and benchmark returns proved that the portfolio does not signiﬁcantly outperform the benchmark in any given year.

... dataset for "A Two Year Survey for VLF Emission from Fireballs" raw data in this dataset was gathered by AWESOME system located in Elginfield Observatory located in southern Ontario, Canada. all event spectrogram folder contains the lightcurve/+-2s/+-5s/+-15s spectrogram for all 80 events for rough inspection. no phenomenologically different signals were found in these events non positively correlated events folder contains the 7 events where calculated signal direction matches recorded meteor, and correlated lightning was not recorded in the NLDN database. in this folder, the 2 .mat files are the raw signals for NS(A) and EW(B) channel of AWESOME antenna, filename denotes its time. the offset between AWESOME antenna and ASGARD-SOMN is roughly 1.23+-0.03s. phi.txt in each folder records (in order) the (1)beginning azimuth, (2)ending azimuth, (3)start of luminous flight compared to peak brightness, (4)end of luminous flight compared to peak brightness, and (5)exact time of peak brightness within the second(raw data is only trimmed to be centered around the start of the second of the peak brightness, not the exact time of the peak brightness). The subfolders are named as "sample number of the peak/binsize of spectrogram/time of peak relative to the time of peak brightness", and each subfolder contains +-2ms amplitude, +-10ms amplitude, direction fit, and location within luminous flight of the particular fit.

But 1 day, 7 days or 15 days later, we injected a lethal dose of bacteria in all individuals and monitored their survival rates for 7 days. Obtained data are available in the file "Prigot_DataSurvivals". With the two datasets, you will find enclosed a .txt file (Prigot_DataLegends) giving all legends of the datasets colomn heads.

Reshaping commensal gut microbiota in early life with amoxicillin presents with lower blood pressure

... 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.

... The dataset presented in the article comprises of finger forces of participants during a finger pressing task. The finger pressing task involves the production of fingertip forces using Index, Middle, Ring, and Little (I, M, R&L) fingers of the right hand. During experimentation, first, the participants performed the Maximum Voluntary Contraction (MVC) task, where they were instructed to produce maximum possible force from each finger individually and all together. The MVC task is followed by the finger pressing task that involves two conditions, i.e., without the epilogue and with the epilogue. The epilogue is a particular case of post-trial visual feedback where only the outcome of the just-concluded trial is shown to the participant. The force levels in the experiments of both these cases were normalized with respect to MVC. Fourteen healthy participants were recruited for the experiments and were instructed to produce fingertip forces using four fingers of the right hand with the target line at 15% MVC (15% of the force that they produced in the MVC task). Each of the two conditions has 30 trials, and the subjects performed 60 trials in total for the complete experiment apart from the MVC task. A single trial of both the conditions lasted for sixteen seconds, where for the initial eight seconds, there is visual feedback followed by the visual occlusion period where there is no visual feedback. For the experiment involving epilogue the participants were shown the feedback of the just-concluded trial, whereas for the without epilogue case, they were not given any post-trial feedback. The dataset consists of three files; the first file has the data of Maximum Voluntary Contraction (MVC) data, the second file has the data of without epilogue case, and the third file has the data of with epilogue case.
