BACKGROUND: The 6-minute walk test (6MWT) is a simple functional test that can predict exercise capacity and is widely employed to assess treatment outcomes. Although mortality with transcatheter mitral valve repair (TMVr) using the MitraClip (Abbott Vascular, Menlo Park, CA) is significantly less than for open mitral valve surgery in high-risk patients, identifying which patient will benefit the most from TMVr remains a concern. There are limited prognostic metrics guiding patient selection and, no studies have reported relationship between prolonged hospitalization and 6MWT...

REVIEW
Adam Morton, Stephanie Teasdale
Accurate assessment of the pregnant patient in the ED depends on knowledge of physiological changes in pregnancy, and how these changes may impact on pathology tests, appearance on point-of-care ultrasound and electrocardiography. In addition the emergency physician needs to be cognisant of disorders that are unique to or more common in pregnancy. Part 1 of this review addresses potential deviations in laboratory investigation reference intervals resulting from physiological alterations in pregnancy, and the important causes of abnormal laboratory results in pregnancy...

Jing Gao, Huijuan Guo, Yucheng Sun, Feng Ge
BACKGROUND: The positive effects of nitrogen fertilization on the performance of phytophagous insects have been extensively reported, the physiological and molecular basis involved, however, are largely unclear. Here, we experimentally test whether the enhancement of juvenile hormone (JH) is responsible for the increased weight and fecundity of pea aphid (Acyrthosiphon pisum) under nitrogen fertilization. RESULTS: Aphids fed on Medicago truncatula with nitrogen fertilization have more amino acids content, greater weight at the 4th instar and adult stage, and produce more offspring than those without nitrogen fertilization...

NEW FINDINGS: What is the central question of this study? What are the initial metabolic and molecular events that underpin bed rest-induced skeletal muscle deconditioning, and what is the contribution of energy balance? What is the main finding and its importance? A single day of bed rest, irrespective of energy balance, did not lead to overt changes in skeletal muscle gene expression or insulin sensitivity. More than one day of physical inactivity is required to observe the insulin resistance and robust skeletal muscle transcriptional responses associated with bed rest and consequent alterations in energy balance...

Research characterizing transport of nutrients and waste in tissue engineering scaffolds has led to the study of scaffold properties that contribute to permeability and porosity of the scaffold. Both permeability and porosity contribute to the transport properties of the scaffold; however, permeability relates to the degree to which pores are interconnected within the scaffold. This work evaluated permeability for woven polymer fiber scaffolds by modulating the following scaffold parameters: material combination, weave configuration, and fiber geometry...

Henrique B Braz, Selma M Almeida-Santos, Christopher R Murphy, Michael B Thompson
The evolution of viviparity requires eggshell thinning to bring together the maternal uterus and extraembryonic membranes to form placentae for physiological exchanges. Eggshell thinning likely involves reduced activity of the uterine glands that secrete it. We tested these hypotheses by comparing the uterine and eggshell structure and histochemistry among oviparous and viviparous water snakes (Helicops) using phylogenetic methods. Eggshell thinning occurred convergently in all three origins of viviparity in Helicops and was accomplished by the loss of the mineral layer and thinning of the shell membrane...

Several studies suggested a relationship between stress and related mental illnesses, such as depression and osteoporosis. However, it was unclear whether patients with post-traumatic stress disorder (PTSD) were at risk of developing osteoporosis in later life. In this study, 6,041 patients with PTSD and 24,164 age- or sex-matched controls were enrolled between 2002 and 2009 in our study and followed up to the end of 2011. Cases of osteoporosis were identified during the follow-up. Patients with PTSD had an elevated likelihood of developing osteoporosis (HR: 2...

PURPOSE: To introduce and evaluate an image registration technique for robust quantification of CEST acquisitions corrupted by motion. METHODS: The proposed iterative algorithm exploits a low-rank approximation of the z-spectrum (LRAZ), to gradually separate the contrast variation due to saturation at different off-resonance frequencies and accompanying motion. This registration method was first tested in a creatine CEST analysis of a phantom with simulated rigid motion...

BACKGROUND: Our previous works have demonstrated that Helicobacter pylori (Hp) infection can alter histone H3 serine 10 phosphorylation status in gastric epithelial cells. However, whether Helicobacter pylori-induced histone H3 serine 10 phosphorylation participates in gastric carcinogenesis is unknown. We investigate the expression of histone H3 serine 10 phosphorylation in various stages of gastric disease and explore its clinical implication. MATERIALS AND METHODS: Stomach biopsy samples from 129 patients were collected and stained with histone H3 serine 10 phosphorylation, Ki67, and Helicobacter pylori by immunohistochemistry staining, expressed as labeling index...

This study used resting state functional magnetic resonance imaging (rsfMRI) to investigate whole brain networks in patients with persistent postural perceptual dizziness (PPPD). We compared rsfMRI data from 38 patients with PPPD and 38 healthy controls using whole brain and region of interest analyses. We examined correlations among connectivity and clinical variables and tested the ability of a machine learning algorithm to classify subjects using rsfMRI results. Patients with PPPD showed: (a) increased connectivity of subcallosal cortex with left superior lateral occipital cortex and left middle frontal gyrus, (b) decreased connectivity of left hippocampus with bilateral central opercular cortices, left posterior opercular cortex, right insular cortex and cerebellum, and (c) decreased connectivity between right nucleus accumbens and anterior left temporal fusiform cortex...
