PURPOSE: Walking programs improve health outcomes in adults at risk for cardiovascular disease and self-monitoring strategies can improve adherence to such programs. The objective of this study was to determine if a six-month internet-based walking program using web-enhanced pedometers results in more weight loss than walking programs based on time or simple pedometer-step count goals in adults with or at risk for cardiovascular disease (CVD). METHODS: This was a multi-site, randomized controlled trial of 255 male Veterans who were ambulatory, insufficiently active, BMI ≥ 28, and who reported 1 ≥ CVD risk factors...

Background: ADIPOQ gene, which encode for Adiponectin (APN), is sited on chromosome 3q27 and linked to a susceptibility locus for metabolic syndrome (MetS). The ADIPOQ rs266729 G/C gene polymorphism is significantly associated with low APN levels and linked to susceptibility to develop cancer. In addition, decreased APN serum levels are linked with tumor development and progression and inversely associated with markers of inflammation. Here, we investigate the influence of APN rs266729 G/C polymorphism on adipocytokine circulating levels and their association with MetS in colorectal cancer patients (CRC)...

PURPOSE: In minimally invasive interventions assisted by C-arm imaging, there is a demand to fuse the intra-interventional 2D C-arm image with pre-interventional 3D patient data to enable surgical guidance. The commonly used intensity-based 2D/3D registration has a limited capture range and is sensitive to initialization. We propose to utilize an opto/X-ray C-arm system which allows to maintain the registration during intervention by automating the re-initialization for the 2D/3D image registration...

BACKGROUND: Pulse oximeters continuously monitor arterial oxygen saturation. Continuous monitoring of venous oxygen saturation (SvO2) would enable real-time assessment of tissue oxygen extraction (O2E) and perfusion changes leading to improved diagnosis of clinical conditions, such as sepsis. METHODS: This study presents the proof of concept of a novel pulse oximeter method that utilises the compliance difference between arteries and veins to induce artificial respiration-like modulations to the peripheral vasculature...

Background and Aims: Preliminary evidence suggests fermentable carbohydrate restriction might ameliorate functional gastrointestinal symptoms (FGS) in quiescent inflammatory bowel disease (IBD). Our aim was to determine whether fermentable carbohydrates exacerbate FGS in quiescent IBD using a randomised, double-blinded, placebo-controlled, cross-over, re-challenge trial. Methods: Patients with quiescent IBD and FGS responsive to a low FODMAP diet were allocated to a series of 3-day fermentable carbohydrate challenges in random order (fructan, 12 g/d; galacto-oligosaccharides, GOS, 6 g/d; sorbitol, 6 g/d; and glucose placebo, 12 g/d), each separated by a standardised washout period...

BACKGROUND: In Zambia, 14.2% of adults have HIV/AIDS. There has been a substantial and significant increase in patients hospitalized for ischaemic stroke with co-existing HIV infection. However, little is known about the mechanism of stroke in these HIV + ve patients let alone studied in our region. The aim of this pilot study was to explore the association of hypercoagulability state in HIV + ve patients with ischaemic stroke. This was achieved by comparing hypercoagulability state markers between HIV + ve ischaemic stroke patients with HIV-ve and HIV + ve patients with and without ischaemic stroke respectively...

A 2-arm parallel-group randomized controlled trial measured the cost-effectiveness of caries prevention in caries-free children aged 2 to 3 y attending general practice. The setting was 22 dental practices in Northern Ireland. Participants were centrally randomized into intervention (22,600 ppm fluoride varnish, toothbrush, a 50-mL tube of 1,450 ppm fluoride toothpaste, and standardized prevention advice) and control (advice only), both provided at 6-monthly intervals during a 3-y follow-up. The primary outcome measure was conversion from caries-free to caries-active states assessed by calibrated and blinded examiners; secondary outcome measures included decayed, missing, or filled teeth surfaces (dmfs); pain; and extraction...

Hfq is a bacterial protein that is involved in several aspects of nucleic acids metabolism. It has been described as one of the nucleoid associated proteins shaping the bacterial chromosome, although it is better known to influence translation and turnover of cellular RNAs. Here, we explore the role of Escherichia coli Hfq's C-terminal domain in the compaction of double stranded DNA. Various experimental methodologies, including fluorescence microscopy imaging of single DNA molecules confined inside nanofluidic channels, atomic force microscopy, isothermal titration microcalorimetry and electrophoretic mobility assays have been used to follow the assembly of the C-terminal and N-terminal regions of Hfq on DNA...

INTRODUCTION: Eccentric leg cycling (cycle ergometry adapted to impose muscle lengthening contractions) offers an effective exercise for restoring lower-body muscular function, maintaining health, and improving performance in clinical and athletic populations. PURPOSE: We extended this model to the upper body and evaluated the effectiveness of a 7-week eccentric arm cycling (ECCarm) intervention to improve upper-body muscular function. We also explored whether ECCarm would alter arterial function...

Aim: Enhanced recovery after surgery (ERAS) is a multimodal approach that aims to optimize perioperative treatment. Whether elderly patients receiving colorectal surgery can adhere to and benefit from an ERAS approach is uncertain. The aim of this study was to compare patients in different age groups participating in an ERAS program. Method: In this substudy of a randomized controlled trial, we analyzed the interventional ERAS arm of adult patients eligible for laparoscopic or open colorectal resection with regard to the importance of age...

Myxoid melanoma is a rare variant of melanoma, which is characterized by atypical spindle cells and dense mucin deposition in dermis. This tumor is usually seen in elderly people with a similar progress in other variants of melanoma. A 28-year-old male presented to our outpatient clinic with a 6-month history of a slowly growing asymptomatic pink lesion on his arm. Dermoscopic examination revealed pink-white cristalline structures and blue-grayish ovoid globules. The lesion was totally excised with initial diagnosis of basosquamous carcinoma, amelanotic melanoma and basal cell carcinoma...

Cells undergoing meiosis produce haploid gametes through one round of DNA replication followed by two rounds of chromosome segregation. This requires that cohesin complexes, which establish sister chromatid cohesion during S phase, are removed in a stepwise manner. At meiosis I, the separase protease triggers the segregation of homologous chromosomes by cleaving cohesin's Rec8 subunit on chromosome arms. Cohesin persists at centromeres because the PP2A phosphatase, recruited by the shugoshin protein, dephosphorylates Rec8 and thereby protects it from cleavage...

This study aims at evaluating the utility of the population pharmacokinetics approach in therapeutic protein drug-drug-interaction (DDI) assessment. Simulations were conducted for 2 representative victim drugs, methotrexate and trastuzumab, using a parallel-group design with and without the interaction drug. The effect of a perpetrator on the exposure of the victim drug is described as the ratio of clearance/apparent clearance of the victim drug given with or without the perpetrator. The power of DDI assessment was calculated as the percentage of runs with 90% confidence interval of the estimated DDI effect within 80% to 125% for the scenarios of no DDI, benchmarked with the noncompartmental approach with intensive sampling...

In dividing cells, DNA replication occurs in a precise order, but many questions remain regarding the mechanisms of replication timing establishment and regulation. We now have generated genome-wide, high-resolution replication timing maps throughout zebrafish development. Unexpectedly, in the rapid cell cycles preceding the midblastula transition, a defined timing program was present that predicted the initial wave of zygotic transcription. Replication timing was thereafter progressively and continuously remodeled across the majority of the genome, and epigenetic changes involved in enhancer activation frequently paralleled developmental changes in replication timing...

Background -It is currently unknown whether intensive blood pressure (BP) lowering beyond that recommended would lead to more lowering of the risk of Left ventricular hypertrophy (LVH) in patients with hypertension, and whether reducing the risk of LVH explains the reported cardiovascular disease (CVD) benefits of intensive BP lowering in this population. Methods -This analysis included 8,164 participants (mean age 67.9 years, 35.3% women, 31.2% blacks) with hypertension but no diabetes from the Systolic Blood Pressure Intervention (SPRINT) Trial; 4,086 randomly assigned to intensive BP lowering (target systolic BP<120mmHg) and 4,078 assigned to standard BP lowering (target systolic BP <140mmHg)...
