Loss of Drosophila Vps16A enhances autophagosome formation through reduced Tor activity

The HOPS tethering complex facilitates autophagosome-lysosome fusion by binding to Syx17 (Syntaxin 17), the autophagosomal SNARE. Here we show that loss of the core HOPS complex subunit Vps16A enhances autophagosome formation and slows down Drosophila development. Mechanistically, Tor kinase is less active in Vps16A mutants likely due to impaired endocytic and biosynthetic transport to the lysosom

Multiscale directed self-assembly of composite microgels in complex electric fields

This study explored the application of localized electric fields for reversible directed self-assembly of colloidal particles in 3 dimensions. Electric field microgradients, arising from the use of micro-patterned electrodes, were utilized to direct the localization and self-assembly of polarizable (charged) particles resulting from a combination of dielectrophoretic and multipolar forces. Deioniz

An electron poor iridium pincer complex for catalytic alkane dehydrogenation

A novel electron deficient 4,6-bis(trifluoromethyl)-1,3-phenylene diphosphinite ligand 4 was developed and synthesized. Reaction of Ir precursors with ligand 4 gave chloro(hydride) pincer complex 5, which demonstrated a higher TON in alkane dehydrogenation reactions compared to similar phosphinite based pre-catalysts. The formation of cyclooctene (COE) and tert-butylethylene adducts of the 14e cat

Engineering considerations on skewing of an interior permanent magnet synchronous machine for parallel hybrid electric heavy vehicles

The focus of this paper is on investigating the influence of skewing on the torque production of an Interior Permanent Magnet Synchronous Machine (IPMSM). The machine is designed as a traction machine according to the requirements of a parallel hybrid electric commercial heavy vehicle. In order to meet the requirements, the machine is designed with a speed higher than that of the conventional powe

Frequent visitors at the psychiatric emergency room – A literature review

Frequent visitors at the psychiatric emergency room (PER) constitute a small subgroup of patients, yet they are responsible for a disproportionate number of visits and thus claim considerable resources. Their needs are often left unmet and their repetitive visits reflect their dissatisfaction as well as that of PERs' staff. Motivated by these dilemmas, this study systematically reviews the literat

Sepsis Alert – a triage model that reduces time to antibiotics and length of hospital stay

Objective: To study if a modified triage system at an Emergency Department (ED) combined with educational efforts resulted in reduced time to antibiotics and decreased length of hospital stay (LOS) for patients with severe infection. Methods: A retrospective, observational study comparing patients before and after the start of a new triage model at the ED of a University Hospital. After the implem

Temperature responsive lipid liquid crystal layers with embedded nanogels

Polymer nanogels are embedded within layers consisting of a nonlamellar liquid crystalline lipid phase to act as thermoresponsive controllers of layer compactness and hydration. As the nanogels change from the swollen to the collapsed state via a temperature trigger, they enable on-demand release of water from the mixed polymer-lipid layer while the lipid matrix remains intact. Combining stimuli-r

The association between adult attained height and sitting height with mortality in the European prospective investigation into cancer and nutrition (EPIC)

Adult height and sitting height may reflect genetic and environmental factors, including early life nutrition, physical and social environments. Previous studies have reported divergent associations for height and chronic disease mortality, with positive associations observed for cancer mortality but inverse associations for circulatory disease mortality. Sitting height might be more strongly asso

17β-estradiol regulates the expression of apolipoprotein M through estrogen receptor α-specific binding motif in its promoter

Background: We have previously demonstrated that estrogen could significantly enhance expression of apolipoprotein M (apoM), whereas the molecular basis of its mechanism is not fully elucidated yet. To further investigate the mechanism behind the estrogen induced up-regulation of apoM expression. Results: Our results demonstrated either free 17β-estradiol (E2) or membrane-impermeable bovine serum

The role of pebble fragmentation in planetesimal formation I. Experimental study

Previous work on protoplanetary dust growth shows a halt at centimeter sizes owing to the occurrence of bouncing at velocities of 0.1 m s-1 and fragmentation at velocities ≳;1 m s-1. To overcome these barriers, spatial concentration of centimeter-sized dust pebbles and subsequent gravitational collapse have been proposed. However, numerical investigations have shown that dust aggregates may underg

Tensions in the Field of Health Care : Knowledge Networks and the Evidence-based Practice: An Action Research Approach

Empirically, this thesis has focused on nine research and development (R&D) networks set up to promote a professional approach to care and strengthen the collaboration between health care sectors in a Swedish health care setting. The research project was embedded in an action research approach intended to encourage network development by means of a dialogical process. The specific research que

Comment on Possamai, Turner, Roose, Dagistanli and Voyce/2. : The "fatwa" chaos, the multiplication of competent authorities, and the state

The new forms of communication facilitated by the IT revolution have provided followers of various interpretations of Islam to participate in the newly opened public spheres. More and more Muslims find it possible to choose among these competing authorities and to select a suitable fatwa, to solve problems of everyday life and to smooth adjustments to living in the new environments. IT revolution

Use and definitions of perioperative mortality rates in low-income and middle-income countries : a systematic review

BACKGROUND: Aggregate and risk-stratified perioperative mortality rates (POMR) are well-documented in high-income countries where surgical databases are common. In many low-income and middle-income country (LMIC) settings, such data are unavailable, compromising efforts to understand and improve surgical outcomes. We undertook a systematic review to determine how POMR is used and defined in LMICs
