BACKGROUND: Blood collection through intravenous (IV) catheters is a common practice at emergency departments (EDs). This technique is associated with higher in vitro hemolysis rates and may even be amplified by the use of vacuum collection tubes. Our aim was to investigate the association of five different vacuum tubes with hemolysis rates in comparison to an aspiration system under real-life conditions and to propose an equation to estimate the amount of hemolysis, depending on the vacuum collection tube type...

Decades of research have documented how sex workers worldwide, particularly female sex workers (FSWs), shoulder a disproportionate burden of the HIV epidemic. In India, although a substantial progress has been made in controlling the epidemic, its prevalence among FSWs and the Devadasis (also called traditional sex workers) in northern Karnataka is still significantly high. On the other hand, much of the HIV prevention research has focused on their mapping and size estimation, typologies, bio-behavioural surveillance, condom use and other prevention technologies...

: Rhinoviruses are the most common cause of the common cold. Their many distinct lineages fall into "major" and "minor" groups that use different cell-surface receptors to enter host cells. Minor-group rhinoviruses are more immunogenic in laboratory studies, although their patterns of transmission and their cold symptoms are broadly similar to those of the major group. Here we present evolutionary evidence that minor-group viruses are also more immunogenic in humans. A key finding is that rates of amino-acid substitution at exposed sites in the capsid proteins VP2, VP3 and VP1 tend to be elevated in minor-group relative to major-group viruses, while rates at buried sites show no consistent differences...

Training physicians to be effective practitioners throughout their careers begins in undergraduate medical education with particular focus on self-directed inquiry, professional and interprofessional development, and competency-based assessment. A select number of medical schools are restructuring their curricula by placing the student at the center of content delivery to enhance the learning experience. While this restructuring may benefit the adult learner, administrators often make assumptions about how students will perceive and respond to such innovative and unfamiliar educational concepts...

Soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNAREs) are universal molecular engines that drive membrane fusion. Particularly, synaptic SNAREs mediate fast calcium-triggered fusion of neurotransmitter-containing vesicles with plasma membranes for synaptic transmission, the basis of all thought and action. During membrane fusion, complementary SNAREs located on two apposed membranes (often called t- and v-SNAREs) join together to assemble into a parallel four-helix bundle, releasing the energy to overcome the energy barrier for fusion...

Extracellular vesicles (EVs), including exosomes, play a key role in inter and intracellular communication, promoting the proliferation and invasion of recipient cells to support tumor growth and metastasis. Metastasis comprises multiple steps that first include the detachment of tumor cells through epithelial to mesenchymal transition (EMT), allowing the physical dissemination to distant organs. Thereafter, cancer-derived exosomes are still critical components for preparing the tumor microenvironment by (i) enabling tumor cells to escape from the immunological surveillance and (ii) arranging the pre-metastatic site for the engraftment of detached cancer cells...

Directed acyclic graphs (DAGs), which offer systematic representations of causal relationships, have become an established framework for the analysis of causal inference in epidemiology, often being used to determine covariate adjustment sets for minimizing confounding bias. DAGitty is a popular web application for drawing and analysing DAGs. Here we introduce the R package 'dagitty', which provides access to all of the capabilities of the DAGitty web application within the R platform for statistical computing, and also offers several new functions...

Problems in fairly allocating welfare and health resources are very often located in the spaces where citizens interact directly with state workers. This study draws on observations of doctor-patient encounters in disability assessments for the South African disability grant (DG) to examine how doctor-patient interactions and patient agency shape social welfare allocation in a context of high poverty and inequality. Data were gathered via interviews with healthcare workers and observations of doctor-patient interactions in twelve clinics and three hospitals in the Western Cape province between October 2013 and August 2014...

Prior research conceptualised action understanding primarily as a kinematic matching of observed actions to own motor representations but has ignored the role of object information. The current study utilized fMRI to identify (a) regions uniquely involved in encoding the goal of others' actions, and (b) to test whether these goal understanding processes draw more strongly on regions involved in encoding object semantics or movement kinematics. Participants watched sequences of instrumental actions while attending to either the actions' goal (goal task), the movements performed (movement task) or the objects used (object task)...

BACKGROUND: Cellulases are key player in the hydrolyzation of cellulose. Unfortunately, this reaction is slow and a bottleneck in the process chain from biomass to intermediates and biofuels due to low activities of the enzymes. To overcome this draw back, a lot of effort is put into the area of protein engineering, to modify these enzymes by directed evolution or rational design. Huge clone libraries are constructed and have to be screened for improved variants. High-throughput screening is the method of choice to tackle this experimental effort, but up to now only a few process steps are adapted to automated platforms and little attention has been turned to the reproducibility of clone rankings...

REVIEW
Ofer Feinerman, Amos Korman
The concerted responses of eusocial insects to environmental stimuli are often referred to as collective cognition at the level of the colony. To achieve collective cognition, a group can draw on two different sources: individual cognition and the connectivity between individuals. Computation in neural networks, for example, is attributed more to sophisticated communication schemes than to the complexity of individual neurons. The case of social insects, however, can be expected to differ. This is because individual insects are cognitively capable units that are often able to process information that is directly relevant at the level of the colony...

Low levels of employee trust in top leaders pose challenges to organizations with respect to retention, performance, and profits. This research examines how trust in top leaders can be fostered through the relationships individuals have with their direct leaders. We propose a trickle-up model whereby trust in direct leaders exerts an upward influence on trust in top leaders. Drawing on the group value model, we predict that direct leaders' procedural justice serves as the key mechanism in facilitating the trickle-up process...
