Ultra-low-level measurements of radionuclides in air have been conducted at the Savannah River National Laboratory (SRNL) to determine the atmospheric concentration of fission products released following the Fukushima Daiichi reactor accident on March 11, 2011. Air filter samples were acquired from two high-volume collection systems (a traditional filter-based system and an electrostatic precipitator-based system) to monitor airborne radionuclide concentrations in the period covering from 2 weeks to 3 years after the disaster. The world-wide spread of low-level concentrations of airborne fission products from the Fukushima event provided a unique opportunity to demonstrate SRNL's electrostatic particle collection technology and other improvements in environmental monitoring developed at the Savannah River Site (SRS).

Collegiate recovery programs (CRPs) offer resources and programming for postsecondary students in addiction recovery to ensure they can initiate or maintain their recovery and complete college. To achieve these goals, CRPs offer a variety of activities that research and theory suggests should produce positive outcomes among their students; yet the lack of systematic evaluation research in this area means it is unknown which programming components may drive outcomes. Recovery capital theory posits a variety of factors at multiple ecological levels that might influence students' recovery experience and their engagement and success in community programs like CRPs.

Plant respiration can theoretically be fueled by and dependent upon an array of central metabolism components; however, which ones are responsible for the quantitative variation found in respiratory rates is unknown. Here, large-scale screens revealed 2-fold variation in nighttime leaf respiration rate (R) among mature leaves from an Arabidopsis () natural accession collection grown under common favorable conditions. R variation was mostly maintained in the absence of genetic variation, which emphasized the low heritability of R and its plasticity toward relatively small environmental differences within the sampling regime.

Article Synopsis
  • Intracellular protein inclusions are key features in ALS, and their role is still unclear.
  • Peripherin, a protein associated with ALS, might lead to harmful inclusion formation due to abnormal splicing, resulting in aggregation-prone variants.
  • This study found that different peripherin forms create distinct inclusion types, affect protein expression, and may help protect against oxidative stress in nerve cells, highlighting their potential significance in ALS research.

Agriculture requires a second green revolution to provide increased food, fodder, fiber, fuel and soil fertility for a growing population while being more resilient to extreme weather on finite land, water, and nutrient resources. Advances in phenomics, genomics and environmental control/sensing can now be used to directly select yield and resilience traits from large collections of germplasm if software can integrate among the technologies. Traits could be Captured throughout development and across environments from multi-dimensional phenotypes, by applying Genome Wide Association Studies (GWAS) to identify causal genes and background variation and functional structural plant models (FSPMs) to predict plant growth and reproduction in target environments.

Background: The high affinity tyrosine kinase receptor, TrkB, is the primary receptor for brain derived neurotrophic factor (BDNF) and plays an important role in development, maintenance and plasticity of the striatal output medium size spiny neuron. The striatal BDNF/TrkB system is thereby implicated in many physiologic and pathophysiologic processes, the latter including mood disorders, addiction, and Huntington's disease. We crossed a mouse harboring a transgene directing cre-recombinase expression primarily to postnatal, dorsal striatal medium spiny neurons, to a mouse containing a floxed TrkB allele (fB) mouse designed for deletion of TrkB to determine its role in the adult striatum.

Chiral N-heterocyclic carbenes (NHCs) promote the asymmetric formal [4 + 2] cycloaddition of alkylarylketenes with β,γ-unsaturated α-ketocarboxylic esters and amides. Divergent diastereoselectivity is observed in this process, with γ-aryl-β,γ-unsaturated α-ketocarboxylic esters and amides giving preferentially syn-dihydropyranones (up to 68 : 32 dr syn : anti, up to 98% ee), while γ-alkyl-derivatives generate anti-dihydropyranones (up to 18 : 82 dr syn : anti, up to 75% ee).

Huntington's disease (HD), caused by a CAG repeat expansion in the huntingtin (HTT) gene, is characterized by abnormal protein aggregates and motor and cognitive dysfunction. Htt protein is ubiquitously expressed, but the striatal medium spiny neuron (MSN) is most susceptible to dysfunction and death. Abnormal gene expression represents a core pathogenic feature of HD, but the relative roles of cell-autonomous and non-cell-autonomous effects on transcription remain unclear.

The relevance of the melanocortin system to sexual activity is well established, and nonselective peptide agonists of the melanocortin receptors have shown evidence of efficacy in human sexual dysfunction. The role of the MC4 receptor subtype has received particular scrutiny, but the sufficiency of its selective activation in potentiating sexual response has remained uncertain owing to conflicting data from studies in preclinical species. We describe here the discovery of a novel series of small-molecule MC4 receptor agonists derived from library hit 2.

A series of aryloxyazetidines, aryloxypyrrolidines and aryloxypiperidines were designed based on structural overlap with previously reported arylpyrazine Oxytocin antagonists. Similarly high levels of Oxytocin antagonism were achievable in these new series. Several aryloxyazetidines also showed high levels of selectivity, with one compound, 25, displaying promising in vivo pharmacokinetics and significantly improved aqueous solubility over related compounds containing a biaryl substituent.

Background: Emergency physicians commonly encounter low-probability/high-morbidity decisions, and chest pain is a prime example. Negative outcomes are improbable but feared, resulting in substantially more patients admitted for chest pain than have important disease. The literature gives little guidance on patient preferences for decision-making when the negative outcomes are unlikely but potentially severe.

Feedback Expert System for Emergency Medical Services (EMS) Documentation (FEED) has a rule-based knowledge base (KB) that was verified against specifications in a focus group consisting of six experts. The focus group suggested changes in almost all rules discussed, indicating that the KB did not meet specifications at that stage of development. However, enough information was gathered to address these issues in the next iteration of development.
