A bacterial strain, designated IMCC26223T, was isolated from an oligotrophic freshwater lake, Lake Soyang, Korea. Cells of strain IMCC26223T were Gram-staining negative, strictly aerobic, non-motile and short-rod-shaped. Growth occurred at pH 6-8 (optimum, pH 7.0), at 4-25 °C (optimum, 15 °C) and with 0-0.5 % (w/v) NaCl (optimum, 0 %). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain IMCC26223T was identified as a member of the genus Flavobacterium and most closely related to Flavobacterium fluvii H7T (97...

We show that worker wellbeing is determined not only by the amount of compensation workers receive but also by how compensation is determined. While previous theoretical and empirical work has often been preoccupied with individual performance-related pay, we find that the receipt of a range of group-performance schemes (profit shares, group bonuses and share ownership) is associated with higher job satisfaction. This holds conditional on wage levels, so that pay methods are associated with greater job satisfaction in addition to that coming from higher wages...

Thanh Dang, Cheryl Ingram-Smith
Acetate kinase (ACK; E.C. 2.7.2.1), which catalyzes the interconversion of acetate and acetyl phosphate, is nearly ubiquitous in bacteria but is present only in one genus of archaea and certain eukaryotic microbes. All ACKs utilize ATP/ADP as the phosphoryl donor/acceptor in the respective directions of the reaction (acetate + ATP [Formula: see text] acetyl phosphate + ADP), with the exception of the Entamoeba histolytica ACK (EhACK) which uses pyrophosphate (PPi)/inorganic phosphate (Pi) (acetyl phosphate + Pi  [Formula: see text] acetate + PPi)...

BACKGROUND: Negative psychosocial consequences have been reported for children with auditory processing disorder (APD). The current literature surrounding APD does not sufficiently address the emotional and psychological consequences of living with the disorder. It is recommended that data be collected from multiple sources, including the child living with APD. Subjective reports of the perceptions of children with APD and their families have real-life validity and can inform clinical decisions and guide future research...

OBJECTIVES: To explore the roles of miR-130b-3p and miR-301b-3p which may regulate Rb1-inducible coiled-coil 1 (Rb1cc1) expression during myogenic differentiation of chicken primary myoblasts. RESULTS: After 4 days of myogenic differentiation, myotubes appeared and after 6 days the cells fused to each other and expression of MyHC could be detected by immunofluorescence staining. TargetScan and RNAhybrid 2.2 showed miR-130b-3p and miR-301b-3p were well complementary with the target site of Rb1cc1 3'-untranslated region (3'-UTR)...

BACKGROUND: Among early adolescents in the United States (U.S.), the prevalence of cigarette smoking is at its lowest level in recent decades. Nonetheless, given the risks of smoking in early development, it remains critically important to study both risk factors for smoking and risks from smoking. This longitudinal study with U.S. early adolescents examines smoking initiation and tests a model of reciprocal prediction between ever smoking and the personality trait of urgency (i.e., mood-based impulsivity), a trait that increases risk for multiple forms of dysfunction...

Cong Peng, Rob M A Nelissen, Marcel Zeelenberg
Receiving favors is often a mixed blessing and commonly triggers two emotions: the positive emotion gratitude and negative emotion indebtedness. In three studies, we examined the hypothesis that gratitude and indebtedness have distinct functions in social exchange. Contrary to current views, we believe that the function of gratitude does not primarily reside in facilitating social exchange. Instead, we propose that indebtedness motivates people to repay favours received, and thus accounts for most of the prosocial effects commonly attributed to gratitude...

Monica Lodi, Fedde W Meijer, Joris M Koene
Promoted by sexual selection, males usually adopt different ways to increase their fertilization chances. In many insect taxa males donate nuptial gifts, together with sperm, which represent a valuable additional nutrient source that females can use to provision eggs. This has also been suggested to occur in simultaneous hermaphrodites, organisms with both sex functions. In theory, donation of nuptial gifts or extra nutrients might work in hermaphrodites that mate unilaterally (one-way donation of ejaculates), but will not be effective when these organisms mate reciprocally (mutual exchange of ejaculates), since on average each partner would receive the amount it also transfers...

This study examines possible bidirectional relationships between emotion regulation and motives related to consuming palatable foods during adolescence. Participants included 79 adolescents (96% African American) who took part in Waves 2 and 3 of the Coping with Violence Study. The youth were recruited from four public middle schools serving low income, urban communities in Birmingham, AL. Participants completed self-report measures of emotion regulation and indicated different motives for consuming tasty foods and drinks at both waves...

This study aimed at moving beyond previous research on couple therapy efficacy by examining moment-by-moment proximal couple and therapist interactions as well as final treatment outcomes and their reciprocal association. Seven hundred four episodes of dyadic coping within 56 early therapy sessions, taken from 28 married couples in treatment, were intensively analyzed and processed using a mixed-methods software (T-LAB). Results showed that negative dyadic coping was self-perpetuating, and therapists tended to passively observe the negative couple interaction; on the contrary, positive dyadic coping appeared to require a therapist's intervention to be maintained, and successful interventions mainly included information gathering as well as interpreting...

Time-reversal symmetry for elastic wave propagation breaks down in a resonant mass-in-mass lattice whose inner-stiffness is weakly modulated in space and in time in a wave-like fashion. Specifically, one-way wave transmission, conversion and amplification as well as unidirectional wave blocking are demonstrated analytically through an asymptotic analysis based on coupled mode theory and numerically thanks to a series of simulations in harmonic and transient regimes. High-amplitude modulations are then explored in the homogenization limit where a non-standard effective mass operator is recovered and shown to take negative values over unusually large frequency bands...

Reciprocal interactions between cancers and the surrounding microenvironment have an important role in tumour evolution. In this study, our data suggested that through thrombospondin 1 (TSP1), tumour-associated microvessel provides a dormant niche to sustain inactive status of breast invasive ductal carcinoma (IDC) cells. TSP1 levels in the tumour stroma were negatively correlated with vascular indoleamine 2,3-dioxygenase 1 (IDO1) in IDC tissues. IDO1 is an intracellular enzyme initiating the first and rate-limited step of tryptophan breakdown...

BACKGROUND: The best treatment approach for ST-segment elevation myocardial infarction (STEMI) is prompt primary percutaneous coronary intervention (PCI). However, some patients show ST elevation on electrocardiography (ECG), but do not have myocardial infarction. We sought to identify the frequency of and to develop a prediction model for false-positive STEMI. METHODS: This study was conducted in the emergency departments (EDs) of two hospitals using the same critical pathway (CP) protocol to treat STEMI patients with primary PCI...

Trust and trustworthiness contribute to reciprocal behavior and social relationship development. To make better decisions, people need to evaluate others' trustworthiness. They often assess this kind of reputation by learning through repeated social interactions. The present event-related potential (ERP) study explored the reputation learning process in a repeated trust game where subjects made multi-round decisions of investment to different partners. We found that subjects gradually learned to discriminate trustworthy partners from untrustworthy ones based on how often their partners reciprocated the investment, which was indicated by their own investment decisions...
