What makes us feel good? A data-driven investigation of positive emotion experience.

What does it mean to feel good? Is our experience of gazing in awe at a majestic mountain fundamentally different than erupting with triumph when our favorite team wins the championship? Here, we use a semantic space approach to test which positive emotional experiences are distinct from each other based on in-depth personal narratives of experiences involving 22 positive emotions ( = 165; 3,592 emotional events). A bottom-up computational analysis was applied to the transcribed text, with unsupervised clustering employed to maximize internal granular consistency (i.e.

Identification of bacteria in the tracheal swabs of farmed ostriches and their effect on the viability of influenza A virus.

Avian influenza surveillance is a requirement for commercial trade in ostrich products, but influenza A viruses (IAVs) have proven difficult to isolate from ostrich tracheal swabs that test positive using molecular methods. We hypothesized that microbes unique to the ostrich trachea propagate in the transport medium after sampling and affect viral viability. We cultured tracheal swabs from 50 ostriches on 4 farms in South Africa, and recovered and identified 13 bacterial, 1 yeast, and 2 fungal species.

Effect of Porins and bla Expression on Activity of Imipenem with Relebactam in Klebsiella pneumoniae: Can Antibiotic Combinations Overcome Resistance?

Imipenem with relebactam is a novel β-lactam-β-lactamase inhibitor that has activity against most KPC-producing Enterobacteriaceae. Using 10 isolates of KPC-possessing Klebsiella pneumoniae, we assessed the relationship between imipenem-relebactam minimum inhibitory concentrations (MICs) and mechanisms known to contribute to antimicrobial resistance. The effect of adding a second agent was assessed by time-kill experiments.

Reduction in the prevalence of carbapenem-resistant Acinetobacter baumannii and Pseudomonas aeruginosa in New York City.

We compared susceptibilities of Acinetobacter baumannii and Pseudomonas aeruginosa collected during surveillance studies conducted during 2009 and 2013-2014 involving hospitals in New York City. There were significant decreases in the number of carbapenem-resistant A baumannii and P aeruginosa cases during 2013-2014; it appears the institution of effective infection control measures has contributed to this decline. However the number of isolates of A baumannii with OXA-23-type β-lactamase increased during 2013-2014.
