Fecal bacteriotherapy ('stool transplant') can be effective in treating recurrent Clostridium difficile infection, but concerns of donor infection transmission and patient acceptance limit its use. Here we describe the use a stool substitute preparation, made from purified intestinal bacterial cultures derived single healthy donor, to treat C. that had failed repeated standard antibiotics. Thirty-three isolates were recovered sample. Two patients who at least three courses metronidazole or...
Vertebrate corpse decomposition provides an important stage in nutrient cycling most terrestrial habitats, yet microbially mediated processes are poorly understood. Here we combine deep microbial community characterization, community-level metabolic reconstruction, and soil biogeochemical assessment to understand the principles governing assembly during of mouse human corpses on different substrates. We find a suite bacterial fungal groups that contribute nitrogen reproducible network...
Establishing the time since death is critical in every investigation, yet existing techniques are susceptible to a range of errors and biases. For example, forensic entomology widely used assess postmortem interval (PMI), but can from days months. Microbes may provide novel method for estimating PMI that avoids many these limitations. Here we show microbial community changes dramatic, measurable, repeatable mouse model system, allowing be estimated within approximately 3 over 48 days. Our...
Abstract Microbial breakdown of organic matter is one the most important processes on Earth, yet controls decomposition are poorly understood. Here we track 36 terrestrial human cadavers in three locations and show that a phylogenetically distinct, interdomain microbial network assembles during despite selection effects location, climate season. We generated metagenome-assembled genome library from cadaver-associated soils integrated it with metabolomics data to identify links between...
Abstract The Arabidopsis genome contains a family of v-SNAREs: VTI11, VTI12, and VTI13. Only VTI11 VTI12 are expressed at appreciable levels. Although these two proteins 60% identical, they complement different transport pathways when in the yeast vti1 mutant. was identified recently as mutated gene shoot gravitropic mutant zig. Here, we show that vti11 zig has defects vascular patterning auxin transport. An T-DNA insertion mutant, vti12, had normal phenotype under nutrient-rich growth...
We present the preliminary design of WEAVE next generation spectroscopy facility for William Herschel Telescope (WHT), principally targeting optical ground-based follow up upcoming (LOFAR) and spacebased (Gaia) surveys. is a multi-object multi-IFU utilizing new 2 degree prime focus field view at WHT, with buffered pick place positioner system hosting 1000 (MOS) fibres or to 30 integral units each observation. The are fed single spectrograph, pair 8k(spectral) x 6k (spatial) pixel cameras,...
Abstract The vacuole occupies most of the volume plant cells; thus, tonoplast marker δ-tonoplast intrinsic protein-green fluorescent protein delineates cell shape, for example, in epidermis. This permits rapid identification mutants. Using this strategy, we identified shape phenotype-1 (csp-1) mutant Arabidopsis thaliana. Beyond an absence lobes pavement cells, phenotypes included reduced trichome branching, altered leaf serration and stem increased stomatal density. result from a point...
Intracluster stellar populations are a natural result of tidal interactions in galaxy clusters. Measuring these is difficult, but important for understanding the assembly most massive galaxies. The Coma cluster one nearest truly clusters, and host to correspondingly large system globular clusters (GCs). We use imaging from HST/ACS Cluster Survey present first definitive detection population intracluster GCs (IGCs) that fills core not associated with individual GC surface density profile...
We present scaling relations between structural properties of nuclear star clusters and their host galaxies for a sample early-type dwarf observed as part the Hubble Space Telescope (HST) Advanced Camera Surveys (ACS) Coma Cluster Survey.We have analysed light profiles 200 in magnitude range 16.0 < m F814W 22.6 mag, corresponding to -19.0 M -12.4 mag.Nuclear are detected 80 per cent galaxies, thus doubling HST-observed with clusters.We confirm that cluster detection fraction decreases...
Death investigations often include an effort to establish the postmortem interval (PMI) in cases which time of death is uncertain. The can lead identification deceased and validation witness statements suspect alibis. Recent research has demonstrated that microbes provide accurate clock starts at relies on ecological change microbial communities normally inhabit a body its surrounding environment. Here, we explore how build most robust Random Forest regression models for prediction PMI by...
An Integrated Sounding System (ISS) that combines state-of-the-art remote and in situ sensors into a single transportable facility has been developed jointly by the National Center for Atmospheric Research (NCAR) Aeronomy Laboratory of Oceanic Administration (NOAA/AL). The instrumentation each ISS includes 915-MHz wind profiler, Radio Acoustic (RASS), an Omega-based NAVAID sounding system, enhanced surface meteorological station. general philosophy behind is integration various measurement...
We present images of extended Hα clouds associated with 14 member galaxies in the Coma cluster obtained from deep narrowband imaging observations Suprime-Cam at Subaru Telescope. The parent are distributed farther than 0.2 Mpc peak X-ray emission cluster. Most bluer g − r ≈ 0.5 and they account for 57% blue (g < 0.5) bright (r 17.8 mag) central region They reside near red- blueshifted edges radial velocity distribution galaxies. Our findings suggest that most were recently captured by...
We have used new deep observations of the Coma cluster from Galaxy Evolution Explorer to visually identify 13 star-forming galaxies with asymmetric morphologies in ultraviolet (UV). Aided by wide-field optical broad-band and Hα imaging, we interpret features as being due star formation within gas stripped interaction environment. The selected objects display a range structures broad fan-shaped systems filaments knots (‘jellyfish’) narrower smoother tails extending up 100 kpc length. Some...
Carrion decomposition is an ecologically important natural phenomenon influenced by a complex set of factors, including temperature, moisture, and the activity microorganisms, invertebrates, scavengers. The role soil microbes as decomposers in this process essential but not well understood represents knowledge gap carrion ecology. To better define sources decomposition, lab-reared mice were decomposed on either (i) with intact microbial community or (ii) that was sterilized. We characterized...
