BACKGROUND: Physical activity (PA) in university students has not been analyzed with specific questionnaires tailored to this population. Therefore, the purpose of this study was to analyse the validity of three PA questionnaires developed on other populations comparing with accelerometer values: counts and moderate to vigorous PA (MVPA) calculated with uniaxial and triaxial cut points. METHODS: 145 (92 women) university students from Spain wore an accelerometer GT3X or GTX+ to collect PA data of 7 full days...

PURPOSE: 4D-MRI based on resorting of 2D-cine-MRI images shows great potential to assess tumor motion more accurately compared to 4D-CT, however, it suffers from low through-plane resolution and stitching artifacts. 4D-MRI based on 3D acquisition results in stitching-artifact-free images with high in-plane and through-plane resolutions. In this study, we report our early clinical experience of a prototype 4D-MRI sequence with 3D stack-of-stars (SOS) trajectory for internal target volume (ITV) definition...

This study aimed to evaluate changes in tibial bone speed of sound (SOS) over time, in preterm and term infants during infancy, in addition to identifying factors influencing the development of tibial SOS during infancy. Preterm (n = 155) and term (n = 65) infants were enrolled in this study. Tibial bone SOS was measured using quantitative ultrasonography (QUS) on the left tibia of newborn infants after birth (within 7 days), at 1 month old, and then every 2 months until subjects were approximately 12-15 months old...

PURPOSE/OBJECTIVE: Personality has been linked to cognitive appraisal and health outcomes; however, research specific to traumatic brain injury (TBI) has been sparse. Gray's theory of behavioral inhibition system and behavioral activation system (BIS/BAS) offers a neurobiologic view of personality that may be especially relevant to neurobehavioral change associated with TBI. The present study examined theoretical and psychometric issues of using the BIS/BAS scale among adults with TBI as well as BIS/BAS personality correlates of TBI...

Student effort on large-scale assessments has important implications on the interpretation and use of scores to guide decisions. Within the United States, English Language Learners (ELLs) generally are outperformed on large-scale assessments by non-ELLs, prompting research to examine factors associated with test performance. There is a gap in the literature regarding the test-taking motivation of ELLs compared to non-ELLs and whether existing measures have similar psychometric properties across groups. The Student Opinion Scale (SOS; Sundre, 2007) was designed to be administered after completion of a large-scale assessment to operationalize students' test-taking motivation...

OBJECTIVE: Stigmatization is common in people with chronic skin conditions and may also affect their significant others (SOs). The fast and implicit processing of stigmatization-related stimuli has received little attention in these populations; however, such knowledge may offer indications for new treatment methods. This study aimed to investigate implicit processing of stigmatization-related stimuli in people with skin conditions and their SOs. METHOD: A modified Stroop task and 2 approach-avoidance tasks were administered to participants with chronic skin conditions (alopecia: n = 50 and psoriasis: n = 50); their significant others (alopecia SOs: n = 47 and psoriasis SOs: n = 50); and controls (n = 50)...

BACKGROUND: Ecological models are currently the most used approaches to classify and conceptualise determinants of sedentary behaviour, but these approaches are limited in their ability to capture the complexity of and interplay between determinants. The aim of the project described here was to develop a transdisciplinary dynamic framework, grounded in a system-based approach, for research on determinants of sedentary behaviour across the life span and intervention and policy planning and evaluation...

Hepatic veno-occlusive disease, also called sinusoidal obstruction syndrome (VOD/SOS), is an unpredictable and potentially fatal complication of hematopoietic cell transplantation (HCT) or nontransplantation-associated chemotherapy/radiotherapy. In cases of severe hepatic VOD/SOS, typically defined by associated multiorgan failure (MOF, also known as multiorgan dysfunction), mortality exceeds 80%. Preclinical and early clinical data have provided a rationale for defibrotide treatment in hepatic VOD/SOS. Based on this evidence and in recognition of the dismal prognosis for these patients, defibrotide was made available through an international multicenter compassionate-use program conducted from December 1998 to March 2009...

The simplest forms of mutations, base substitutions, typically have negative consequences, aside from their existential role in evolution and fitness. Hypermutations, mutations on steroids, occurring at frequencies of 10(-2) -10(-4) per base pair, straddle a domain between fitness and death, depending on the presence or absence of regulatory constraints. Two facets of hypermutation, one in Escherichia coli involving DNA polymerase V (pol V), the other in humans, involving activation-induced deoxycytidine deaminase (AID) are portrayed...

OBJECTIVE: The role and mechanisms of insulin receptor internalization remain incompletely understood. Previous trafficking studies of insulin receptors involved fluorescent protein tagging at their termini, manipulations that may be expected to result in dysfunctional receptors. Our objective was to determine the trafficking route and molecular mechanisms of functional tagged insulin receptors and endogenous insulin receptors in pancreatic beta-cells. METHODS: We generated functional insulin receptors tagged with pH-resistant fluorescent proteins between domains...

UNLABELLED: Our laboratory recently discovered that Escherichia coli cells starved for the DNA precursor dGTP are killed efficiently (dGTP starvation) in a manner similar to that described for thymineless death (TLD). Conditions for specific dGTP starvation can be achieved by depriving an E. coli optA1 gpt strain of the purine nucleotide precursor hypoxanthine (Hx). To gain insight into the mechanisms underlying dGTP starvation, we conducted genome-wide gene expression analyses of actively growing optA1 gpt cells subjected to hypoxanthine deprivation for increasing periods...

Cell-to-cell heterogeneity typically evolves due to a manifold of biological and environmental factors and special phenotypes are often relevant for the fate of the whole population but challenging to detect during conventional analysis. We demonstrate a microfluidic single-cell cultivation platform that incorporates several hundred growth chambers, in which isogenic bacteria microcolonies growing in cell monolayers are tracked by automated time-lapse microscopy with spatiotemporal resolution. The device was not explicitly developed for a specific organism, but has a very generic configuration suitable for various different microbial organisms...
