Telomere length dynamics and DNA damage responses.

(B and C) Analysis of microbial community taxonomic structure at the genus level (B) and functional gene content (C) using mMDS of annotated shotgun metagenome sequence data.

GC-MS/MS urine, metabolomics data showed an increase in the, lactic acid/pyruvic acid ratio (Fig. KBR (NYSE: KBR), is proud to be part of the groundbreaking NASA Twins Study , whose newly published findings will help prepare humans for long-term space travel and propel NASA closer to its recently announced goal of sustaining a permanent lunar presence. 6).

explain the development of these symptoms, collectively referred to by NASA as SANS (, including the spaceflight-induced cephalad fluid, shift and associated adaptations. Green and colleagues also saw no changes in levels of microbial diversity during Scott's time on the space station. Samples collected on the ISS were, duration of the mission or returned under ambient, conditions to Earth.

); NNX17AB26G, NNX17AB26G, and. (A) mtRNA content observed in RNA-seq data for the unsorted frozen PBMC (expressed relative to total number of aligned reads).

M. A. Shammas, Telomeres, lifestyle, cancer, and aging. The findings from this study indicate that micro-CT evaluation is a sensitive and reliable method to characterize ocular structure changes. 2D). We also observed a, trend for increased levels of plasma TCA cycle, intermediates in the inflight period, such as, citric acid and malic acid (FDR < 0.10), com-. We now have developed a hypothesis regarding the mechanisms that link 1-carbon pathway genetics and the condition that we suggest calling, "astronaut ophthalmic syndrome."
