STAT: a fast, scalable, MinHash-based k-mer tool to assess Sequence Read Archive next-generation sequence submissions.

Sequence Read Archive submissions to the National Center for Biotechnology Information often lack useful metadata, which limits the utility of these submissions. We describe the Sequence Taxonomic Analysis Tool (STAT), a scalable k-mer-based tool for fast assessment of taxonomic diversity intrinsic to submissions, independent of metadata. We show that our MinHash-based k-mer tool is accurate and scalable, offering reliable criteria for efficient selection of data for further analysis by the scientific community, at once validating submissions while also augmenting sample metadata with reliable, searchable, taxonomic terms.

Effect of ultraviolet-C light on the environmental bacterial bioburden in various veterinary facilities.

Objective: To determine the effect of a mobile UV-C disinfection device on the environmental bacterial bioburden in veterinary facilities.

Samples: 40 swab samples of surfaces from the operating theaters of 3 veterinary hospitals and 1 necropsy laboratory.

Procedures: Various surfaces were swabbed, and collected material was eluted from the swabs in PBSS.

Osteoarticular Infection in Three Young Thoroughbred Horses Caused by a Novel Gram Negative Cocco-Bacillus.

We describe three cases of osteoarticular infection (OAI) in young thoroughbred horses in which the causative organism was identified by MALDI-TOF as . The pattern of OAI resembled that reported with infection in humans. Analysis by 16S rRNA PCR enabled construction of a phylogenetic tree that placed the isolates closer to and , rather than .

Resourcing the Fairytale Country with Wind Power: A Dynamic Material Flow Analysis.

Wind energy is key to addressing the global climate challenge, but its development is subject to potential constraints of finite primary materials. Prior studies on material demand forecasting of wind power development are often limited to a few materials and with low technological resolution, thus hindering a comprehensive understanding of the impact of microengineering parameters on the resource implications of wind energy. In this study, we developed a component-by-component and stock-driven prospective material flow analysis model and used bottom-up data on engineering parameters and wind power capacities to characterize the materials demand and secondary supply potentials of wind energy development in Denmark, a pioneering and leading country in wind power.

Managing Sequence Data.

Nucleotide and protein sequences are the foundation for all bioinformatics tools and resources. Researchers can analyze these sequences to discover genes or predict the function of their products. The INSDC (International Nucleotide Sequence Database-DDBJ/ENA/GenBank + SRA) is an international, centralized primary sequence resource that is freely available on the Internet.

Selective Allosteric Inhibition of MMP9 Is Efficacious in Preclinical Models of Ulcerative Colitis and Colorectal Cancer.

Expression of matrix metalloproteinase 9 (MMP9) is elevated in a variety of inflammatory and oncology indications, including ulcerative colitis and colorectal cancer. MMP9 is a downstream effector and an upstream mediator of pathways involved in growth and inflammation, and has long been viewed as a promising therapeutic target. However, previous efforts to target matrix metalloproteinases (MMPs), including MMP9, have utilized broad-spectrum or semi-selective inhibitors.

Non-catalytic site HIV-1 integrase inhibitors disrupt core maturation and induce a reverse transcription block in target cells.

HIV-1 integrase (IN) is the target for two classes of antiretrovirals: i) the integrase strand-transfer inhibitors (INSTIs) and ii) the non-catalytic site integrase inhibitors (NCINIs). NCINIs bind at the IN dimer interface and are thought to interfere primarily with viral DNA (vDNA) integration in the target cell by blocking IN-vDNA assembly as well as the IN-LEDGF/p75 interaction. Herein we show that treatment of virus-producing cells, but not of mature virions or target cells, drives NCINI antiviral potency.

Objective: To investigate the effect of laser shock peening on the fatigue life and surface characteristics of 3.5-mm-diameter cortical bone screws.

Sample Population: 32 stainless steel, 3.

Stress fractures of the tibia and humerus in Thoroughbred racehorses: 99 cases (1992-2000).

Objective: To determine clinical characteristics of and outcome in Thoroughbred racehorses with tibial or humeral stress fractures.

Design: Retrospective study.

Animals: 99 Thoroughbreds with tibial or humeral stress fractures.

Rous sarcoma virus negative regulator of splicing selectively suppresses SRC mRNA splicing and promotes polyadenylation.

Retroviruses require a balance of spliced and unspliced RNA for efficient replication. Here, we examined the effect of mutations in a splicing suppressor sequence called the negative regulator of splicing (NRS), located within the gag gene of Rous sarcoma virus. While the NRS mutant viruses showed only small changes in the levels of spliced env mRNAs, they had significant increases in src mRNA levels and transformed cells more efficiently than wild-type virus.
