Emergence of multidrug-resistant bacteria causes an urgent need for new generation of antibiotics, which may have a different mechanism of inhibition or killing action from the existing. Here, we report on the design, synthesis, and biological evaluation of thirty-nine coumarin derivatives in order to solve the antibacterial resistance by targeting at the inhibition of biosynthesis pathway of fatty acids. Their antibacterial activities against Escherichia coli, Staphylococcus aureus, Streptococcus agalactiae, and Flavobacterium cloumnare are tested and action mechanism against the key enzyme in bacterial fatty acid synthesis pathway are studied...

Steve W J Kozlowski
Teamwork has been at the core of human accomplishment across the millennia, and it was a focus of social psychological inquiry on small group behavior for nearly half a century. However, as organizations world-wide reorganized work around teams over the past two decades, the nature of teamwork and factors influencing it became a central focus of research in organizational psychology and management. In this article, I reflect on the impetus, strategy, key features, and scientific contribution of "Enhancing the Effectiveness of Work Groups and Teams," by Kozlowski and Ilgen, a review monograph published in Psychological Science in the Public Interest in 2006...

Juan Zhao, Jianping Wang
In this work, anionic effect on water structure and on peptide backbone and water interaction was investigated directly in aqueous solution using thin-layer transmission infrared spectroscopy. The chaotropic anions were found to weaken the water hydrogen-bonding strength and red shift the HOH bending frequency, while the kosmotropic anions were found to strengthen the water hydrogen-bonding network and blue shift the HOH bending frequency. The kosmotropes, especially F-, blue shift the vibrational frequencies of both amide-II and amide-III bands of N-methylacetamide (NMA), indicating NMA is in the "salting-in" state; while the chaotropes (Cl-, NO3-, Br-, I-, and SCN-) red shift the frequencies of the two normal modes, indicating NMA is in the "salting-out" state...

Juvenile social interactions have been shown to influence the dendritic complexity of neurons in the prefrontal cortex. In particular, social play induces pruning of the cells in the medial prefrontal cortex (mPFC), whereas interacting with multiple partners, whether those interactions involve play or not, increases the complexity of cells in the orbital frontal cortex (OFC). Previous studies suggest that these changes differ in their stability during adulthood. In the present study, rats were reared in groups of either four (quads) or two (pairs) and the brains of the rats from each rearing condition were then harvested at 60 days (i...

Protein-carbohydrate interactions are very often mediated by the stacking CH-π interactions involving the side chains of aromatic amino acids such as tryptophan (Trp), tyrosine (Tyr) or phenylalanine (Phe). Especially suitable for stacking is the Trp residue. Analysis of the PDB database shows Trp stacking for 265 carbohydrate or carbohydrate like ligands in 5 208 Trp containing motives. An appropriate model system to study such an interaction is the AAL lectin family where the stacking interactions play a crucial role and are thought to be a driving force for carbohydrate binding...

Structure-function relationships of nine rationally designed ritonavir-like compounds were investigated to better understand the ligand binding and inhibitory mechanism in human drug-metabolizing cytochrome P450 3A4 (CYP3A4). The analogs had a similar backbone and pyridine and tert-butyloxycarbonyl (Boc) as the heme-ligating and terminal groups, respectively. N-Isopropyl, N-cyclopentyl, or N-phenyl were the R1-side group substituents alone (compounds 5a-c) or in combination with phenyl or indole at the R2 position (8a-c and 8d-f subseries, respectively)...

Background: Despite improvements, air pollution still remains a major public health issue. Numerous epidemiological studies have demonstrated the adverse health effects of air pollution exposure based on modeled measures, but only a few have considered the health impact of perceived air quality. Improving our knowledge of individual perceptions is crucial to defining targeted actions and promoting appropriate intervention measures. Our objective is to investigate the relationship between subjective and objective measures of air pollution and to focus on how individual characteristics combined with the neighborhood socioeconomic deprivation index, measured at a fine spatial scale, may or may not alter this relationship...

Polyacrylonitrile (PAN)/carbon nanotube (CNT) composites are used as a precursor for ultrastrong and lightweight carbon fibers. However, the mechanisms of formation and relationships of the nanoscale structure to mechanical and thermal properties have remained uncertain. This study reports on the impact of different degrees of PAN pre-orientation and CNT diameter on the composite properties using molecular dynamics simulation with accurate potentials and comparisons to experimental data. Relationships between the atomically resolved structure, thermal, and mechanical properties are derived...

A broad range of carbon sources have been used to fabricate varieties of carbon quantum dots (CQDs). However, majority of these studies concern on the influence of primary structures and chemical compositions of precursors on the CQDs; it is still unclear that whether the superstructures of carbon sources have effects on the physiochemical properties of the synthetic CQDs. In this work, the concept of molecular assembly is first introduced into design of a new carbon source. Compared with the tropocollagen molecules, the hierarchically assembled collagen scaffolds, as a new carbon source, immobilizes functional groups of the precursors through hydrogen bonds, electrostatic attraction and hydrophobic forces...

Objective The Energy Envelope Theory of myalgic encephalomyelitis and chronic fatigue syndrome postulates that individuals with myalgic encephalomyelitis and chronic fatigue syndrome may experience some increase in functioning if their level of exertion consistently remains within the limits of their available energy. Findings of several studies support this theory; however, the current study is the first to explore how an individual's initial level of available energy may influence the relation between energy envelope maintenance and level of functioning...
