Acromion Marker Cluster (AMC) methods have been shown to accurately track scapula motion during humeral elevation below 90°, however, their accuracy has not been assessed in shoulder girdle motion such as clavicle protraction, retraction, elevation and depression independent of humeral movement. The aim of this study was to examine the reliability and validity of the AMC method to record scapula orientation at end range clavicle protraction, retraction, elevation and depression. The right scapulae of twenty-two female and twenty male asymptomatic volunteers were assessed with an AMC and Scapula Locator (SL) method during end range clavicle protraction, retraction, elevation and depression (without humeral elevation) using an eight-camera 3D movement registration system...

Lyme borreliosis (LB) is the most important human tick-borne disease, but Borrelia genospecies cause different clinical manifestations. Ticks of the genus Ixodes removed from humans between 2006 and 2012 were analysed for Borrelia burgdorferi sensu lato (sl) infections. The majority of ticks originated from the Greater Hanover region in Northern Germany. The engorgement status varied over the entire spectrum from unengorged (no evidence of started blood feeding) to fully engorged. In the present study, prevalence data for B...

OBJECTIVES: This study has investigated the influence of Titanium dioxide nanotubes (TiO2-nt) addition to self-adhesive resin cement on the degree of conversion, water sorption, and water solubility, mechanical and biological properties. METHODS: A commercially available auto-adhesive resin cement (RelyX U200™, 3M ESPE) was reinforced with varying amounts of nanotubes (0.3, 0.6, 0.9wt%) and evaluated at different curing modes (self- and dual cure). The DC in different times (3, 6, 9, 12 and 15min), water sorption (Ws) and solubility (Sl), 3-point flexural strength (σf), elastic modulus (E), Knoop microhardness (H) and viability of NIH/3T3 fibroblasts were performed to characterize the resin cement...

Genetic and environmental factors affect bread wheat plant architecture, which determines grain yield. In this study, we demonstrate that miR156 controls bread wheat plant architecture. We show that overexpression of tae-miR156 in bread wheat cultivar Kenong199 leads to increased tiller number and severe defects in spikelet formation, probably due to the tae-miR156-mediated repression of a group of SQUAMOSA PROMOTER BINDING PROTEIN-LIKE (SPL) genes. Furthermore, we found that the expression of two genes TaBA1 and TaTB1, whose orthologous genes in diverse plant species play conserved roles in regulating plant architecture, is markedly reduced in the tae-miR156-OE bread wheat plants...

BACKGROUND: Sodium lactate has been shown to improve hemodynamics and avoid fluid overload. The objective of this study was to confirm a beneficial effect on fluid balance with sodium lactate infusion and to specify whether the advantage of lactate is related to a negative chloride balance, its particular metabolism, or simply its energy load. METHODS: This was an interventional, randomized, open-label, controlled experimental study. Fifteen female "large white" pigs (2 months old) were challenged with intravenous infusion of Escherichia coli endotoxin...

Chronic Scapholunate ligament (SL) injuries are difficult to treat and can lead to wrist dysfunction. Whilst several tendon reconstruction techniques have been employed in the management of SL instability, SL gap reappearance after surgery has been reported. Using finite element model and cadaveric study data we investigated the performance of the Corella, schapolunate axis (SLAM) and modified Brunelli tenodesis (MBT) techniques. Virtual tenodesis surgery was undertaken in 3D finite element (FE) models to obtain the scapholunate (SL) gap and angle resulting from the three reconstruction techniques...

OBJECTIVES: Over the last 10 years, appropriate workforce utilisation has been an important discussion among healthcare practitioners and policy-makers. The role of healthcare aides (HCAs) has also expanded to improve their utilisation. This evolving role of HCAs in Canada has prompted calls for standardised training, education and scope of practice for HCAs. The purpose of this research was to examine the differences in HCAs training and utilisation in continuing care facilities. DESIGN: From June 2014 to July 2015, we conducted a mixed-method study on HCA utilisation in continuing care...

In plants, microRNA (miRNA)-target complementarity has long been considered the predominant factor determining the silencing outcome of the miRNA-target interaction, although the efficacy of such interactions have rarely been appraised in plants. Here, we perform in planta silencing efficacy assays on seven Arabidopsis MYB genes, all of which contain conserved miR159-binding sites of analogous complementarity. These genes were found to be differentially silenced by miR159; MYB81, MYB97, MYB101, MYB104 and DUO1 were all poorly silenced, whereas MYB33 and MYB65 were strongly silenced...

Surfactants are ubiquitous constituents of commercial and biological systems that function based on complex structure-dependent interactions. Sophorolipid (SL) n-alkyl esters (SL-esters) comprise a group of modified naturally derived glycolipids from Candida bombicola. Herein, micellar self-assembly behavior as a function of SL-ester chain length was studied. Surface tensions as low as 31.2 mN/m and critical micelle concentrations (CMCs) as low as 1.1µM were attained for diacetylated SL-decyl ester (dASL-DE) and SL-octyl ester, respectively...

Various contents of lignin-coated cellulose nanocrystals (L-CNC) were incorporated into methacrylate (MA) resin and their mixture was used to prepare nanocomposites via 3D stereolithography (3D-SL) printing. Gaps were found between the L-CNC and MA matrix in 3D-SL printed nanocomposites before postcure. However, gaps decreased after postcure due to interactions between the L-CNC and MA molecules. Mechanical properties increased with the addition of 0.1% and 0.5% L-CNC after postcure, and the thermal stability was improved at 0...

Xiaozhao Fang, Shaohua Teng, Zhihui Lai, Zhaoshui He, Shengli Xie, Wai Keung Wong
This paper proposes a novel method, called robust latent subspace learning (RLSL), for image classification. We formulate an RLSL problem as a joint optimization problem over both the latent SL and classification model parameter predication, which simultaneously minimizes: 1) the regression loss between the learned data representation and objective outputs and 2) the reconstruction error between the learned data representation and original inputs. The latent subspace can be used as a bridge that is expected to seamlessly connect the origin visual features and their class labels and hence improve the overall prediction performance...

Tat Woon Chao, Liam Geraghty, Pandelis Dimitriou, Simon Talbot
BACKGROUND: Femoral component malrotation is a common cause of patient dissatisfaction after total knee arthroplasty. The sulcus line (SL) is more accurate than Whiteside's line as it corrects for variation in the coronal orientation of the groove. The hypothesis is that averaging the SL and posterior condylar axis (PCA) will reduce femoral malrotation. METHODS: The component was inserted at a position between the SL and PCA in 91 patients. An intraoperative photograph was taken showing the landmarks...

INTRODUCTION: Wearable health devices have become trendy among consumers, but it is not known whether they accurately measure sleep and physical activity parameters. To address this question, we have studied the measured data of two consumer-level activity monitors (Up Move Jawbone(®) (U) and Withings Pulse 02(®) (W)) and compared it with reference methods for sleep and activity recordings, namely the Bodymedia SenseWear Pro Armband(®) actigraph (SWA) and home-polysomnography (H-PSG)...

REVIEW
Shelley Lumba, Asrinus Subha, Peter McCourt
Strigolactones (SLs) are small molecules that act as endogenous hormones to regulate plant development as well as exogenous cues that help parasitic plants to infect their hosts. Given that parasitic plants are experimentally challenging systems, researchers are using two approaches to understand how they respond to host-derived SLs. The first involves extrapolating information on SLs from model genetic systems to dissect their roles in parasitic plants. The second uses chemicals to probe SL signaling directly in the parasite Striga hermonthica...

Multi-dimensional mass spectrometry-based shotgun lipidomics (MDMS-SL) has made profound advances for comprehensive analysis of cellular lipids. It represents one of the most powerful tools in analyzing lipids directly from lipid extracts of biological samples. It enables the analysis of nearly 50 lipid classes and thousands of individual lipid species with high accuracy/precision. The redox imbalance causes oxidative stress, resulting in lipid peroxidation, and alterations in lipid metabolism and homeostasis...

BACKGROUND: Percutaneous dilatational tracheostomy (PDT) in critically ill patients is often led by optical guidance with a bronchoscope. This is not without its disadvantages. Therefore, we aimed to study the feasibility of a recently introduced endotracheal tube-mounted camera (VivaSight™-SL, ET View, Misgav, Israel) in the guidance of PDT. METHODS: We studied 10 critically ill patients who received PDT with a VivaSight-SL tube that was inserted prior to tracheostomy for optical guidance...

INTRODUCTION: An ageing population has become an urgent concern for Asia in recent times. In nursing homes, polypharmacy has also become a compounding issue. Deprescribing practice is an evidence-based strategy to provide a better outcome in this group of patients; however, its implementation in nursing homes is often challenging, and prospective outcome data on deprescribing practice in the elderly is lacking. Our study assesses the implementation of team-care deprescribing to understand the benefits of this practice in geriatric setting and to explore the factors affecting deprescribing practice...
