During mammalian embryonic development, neurons polarize to create distinct cellular compartments of axon and dendrite that inherently differ in form and function, providing the foundation for directional signaling in the nervous system. Polarization results from spatio-temporal segregation of specific proteins' activities to discrete regions of the neuron to dictate axonal vs. dendritic fate. We aim to manipulate axon formation by directed subcellular localization of crucial intracellular protein function...

Ostomy-specific adjustment may or may not predict health-related quality of life (HRQoL) and/or overall quality of life (QoL). A cross-sectional study was conducted among patients recruited from the customer registers of 8 surgical suppliers and pharmacies across Norway between November 2010 and March 2011 to determine which of the 34 items of the Ostomy Adjustment Scale (OAS) are the strongest predictors for HRQoL and overall QoL and to determine the HRQoL and overall QoL of individuals with an ostomy compared to a control group representing the general population...

Limb congenital defects afflict approximately 0.6:1000 live births. In addition to genetic factors, prenatal exposure to drugs and environmental toxicants, represents a major contributing factor to limb defects. Examples of well-recognized limb teratogenic agents include thalidomide, warfarin, valproic acid, misoprostol, and phenytoin. While the mechanism by which these agents cause dymorphogenesis is increasingly clear, prediction of the limb teratogenicity of many thousands of as yet uncharacterized environmental factors (pollutants) remains inexact...

Medical imaging using animal models for human diseases has been utilized for decades; however, until recently, medical imaging of diseases induced by high-consequence pathogens has not been possible. In 2014, the National Institutes of Health, National Institute of Allergy and Infectious Diseases, Integrated Research Facility at Fort Detrick opened an Animal Biosafety Level 4 (ABSL-4) facility to assess the clinical course and pathology of infectious diseases in experimentally infected animals. Multiple imaging modalities including computed tomography (CT), magnetic resonance imaging, positron emission tomography, and single photon emission computed tomography are available to researchers for these evaluations...

Protein-protein interactions perform diverse functions in living organism. The integrative analysis of binding and stabilizing residues will provide insights on the functions of protein-protein complexes. In this work, we constructed a non-redundant dataset of 261 protein-protein complexes and identified binding site residues, stabilizing residues and common to both binding and stabilizing, termed as "key residues". We found that 6.1% of residues are involved in binding and 6.8% of residues are important for folding and stability...

Labial striations on the anterior teeth have been documented in numerous European pre-Neandertal and Neandertal fossils and serve as evidence for handedness. OH-65, dated at 1.8 mya, shows a concentration of oblique striations on, especially, the left I(1) and right I(1), I(2) and C(1), which signal that it was right-handed. From these patterns we contend that OH-65 was habitually using the right hand, over the left, in manipulating objects during some kind of oral processing. In living humans right-handedness is generally correlated with brain lateralization, although the strength of the association is questioned by some...

BACKGROUND: Obesity, eating disorders and unhealthy weight-loss practices have been associated with diminished growth in adolescents worldwide. Interventions that address relevant behavioural dimensions have been lacking in Malaysia. This paper describes the protocol of an integrated health education intervention namely 'Eat Right, Be Positive About Your Body and Live Actively' (EPaL), a primary prevention which aimed to promote healthy lifestyle in preventing overweight and disordered eating among secondary school adolescents aged 13-14 years old...

Background: The Department of Health and Human Services in Victoria provides funded hepatitis B vaccine to many priority groups at risk of acquiring infection. We aimed to determine the uptake of vaccine ordering for at-risk groups over time, to assess any trends and identify any gaps in prevention of hepatitis B for those at risk. Methods: Routinely collected administrative data regarding the indication for vaccine ordered by practitioners were analysed for the period June 2013 to December 2014. Number of doses and courses distributed was determined and compared with the estimated size of the priority populations...

Cuing a location in space produces a short-lived advantage in reaction time to targets at that location. This early advantage, however, switches to a reaction time cost and has been termed inhibition of return (IOR). IOR behaves differently for different response modalities, suggesting that it may not be a unified effect. This letter presents new data from two experiments testing the gradient of IOR with random, continuous cue-target Euclidean distance and cue-target onset asynchrony. This data were then used to train multiple diffusion models of saccadic and manual reaction time for these cuing experiments...

Millions of people want to donate their organs after they die for transplantation, and many of them have registered their wish to do so or told their family and friends about their decision. For most of them, however, this wish is unlikely to be fulfilled, as only a small number of deaths (1% in the United Kingdom) occur in circumstances where the opportunity to donate organs is possible. Even for those who do die in the 'right' way and have recorded their wishes or live in a jurisdiction with a 'presumed consent' system, donation often does not go ahead because of another issue: their families refuse to allow donation to proceed...

Irritable bowel syndrome (IBS) is the most common cause of non-organic recurrent abdominal pain in children. IBS is a clinical diagnosis, which is based on the Rome IV criteria for functional gastrointestinal disorders in children, as well as the patient's history. The diagnosis of IBS is established following the exclusion of organic causes of recurrent abdominal pain. Staggered investigations should be avoided because they might increase the child's and family's anxiety in the absence of an organic diagnosis...

Tryptophan hydroxylase 2 (TPH2) catalyses the initial and rate-limiting step in the biosynthesis of serotonin, which is associated with a variety of disorders such as depression, obsessive compulsive disorder, and schizophrenia. Full-length TPH2 is poorly characterized due to low purification quantities caused by its inherent instability. Three truncated variants of human TPH2 (rch TPH2; regulatory and catalytic domain, NΔ47-rch TPH2; truncation of 47 residues in the N terminus of rch TPH2, and ch TPH2; catalytic domain) were expressed, purified, and examined for changes in transition temperature, inactivation rate, and oligomeric state...

Bioluminescence, which living organisms such as fireflies emit light, has been studied extensively for over half a century. This intriguing reaction, having its origins in nature where glowing insects can signal things such as attraction or defense, is now widely used in biotechnology with applications of bioluminescence and chemiluminescence. Luciferase, a key enzyme in this reaction, has been well characterized; however, the enzymes involved in the biosynthetic pathway of its substrate, luciferin, remains unsolved at present...

The use of live attenuated intravesicular Bacillus Calmette-Guerin (BCG) therapy is a generally accepted safe and effective method for the treatment of superficial transitional cell carcinoma (TCC) of the bladder. Although rare, < 5% of patient's treated with intravesicular BCG therapy may develop potentially serious complications, including localized infections to the genitourinary tract, mycotic aneurysms and osteomyelitis. We present here a case of a 63-year-old male who developed left coronary and multiple peripheral M...

The newly revised 2014 Set of Standards for"Designated Cancer Care Hospitals"mandated the screening of all cancer patients6 for their physical and psychological suffering systematically in both outpatient and inpatient settings as well as rapid response to the suffering detected. It is a step forward as a cancer control policy, but because the pain associated with cancer changes by time depending on factors such as disease progression and treatment, it must be evaluated repeatedly. Simply complying with the standard by measuring once, say on admission or at the initial visit, will not help patients...

Multiple sclerosis (MS) is a complex disease, where several processes can be selected as a target for positron emission topography (PET) imaging. Unlike magnetic resonance imaging (MRI), PET provides specific and quantitative information, and unlike neuropathology, it can be non-invasively applied to living patients, which enables longitudinal follow-up of the MS pathology. In the study of MS, PET can be useful for in vivo evaluation of specific pathological characteristics at various stages of the disease...
