Acinetobacter baumannii produces a variety of capsular polysaccharides (CPS) via genes located at the chromosomal K locus and some KL gene clusters include genes for the synthesis of specific sugars. The structures of K11 and K83 CPS produced by isolates LUH5545 and LUH5538, which carry related KL11a and KL83 gene clusters, respectively, were established by sugar analysis and one- and two-dimensional (1)H and (13)C NMR spectroscopy. Both CPS contain L-rhamnose (L-Rha) and 6-deoxy-L-talose (L-6dTal), and both KL gene clusters include genes for dTDP-L-Rhap synthesis and a tle (talose epimerase) gene encoding an epimerase that converts dTDP-L-Rhap to dTDP-L-6dTalp...

Nicholas J Ray, Damien Hall, John A Carver
Deamidation of Glu147 in human αA-crystallin is common in aged cataractous lenses (Hains and Truscott, Invest. Ophthalmol. Vis. Sci. 2010, 51, 3107). Accordingly, this modification may have a causative effect in cataract. αA-crystallin is a small heat-shock molecular chaperone protein that prevents aggregation of proteins and is the principal defence against crystallin protein unfolding and aggregation in the ageing lens. Deamidated Q147E αA-crystallin was structurally characterised using a variety of spectroscopic and biophysical methods, including NMR, circular dichroism and fluorescence spectroscopy and dynamic light scattering...

PURPOSE: Pre-injury oral anticoagulants are associated with worse outcomes in geriatric (G-60) trauma patients, but there are limited data comparing warfarin with direct oral anticoagulants (DOAC). We sought to compare outcomes in G-60 trauma patients taking pre-injury DOACs vs. warfarin. METHODS: All trauma patients, age ≥60 who were admitted to the hospital and taking an oral anticoagulant pre-injury were retrospectively identified. Patients were excluded if their reason for admission was a suicide attempt or penetrating extremity injury...

BACKGROUND: Measuring and providing feedback about hand hygiene (HH) compliance is a complicated process. Electronic HH monitoring systems have been proposed as a possible solution; however, there is little information available about how to successfully implement and maintain these systems for maximum benefit in community hospitals. METHODS: An electronic HH monitoring system was implemented in 3 community hospitals by teams at each facility with support from the system vendor...

I walk into work thinking about her. The last time I walked through these doors, I wondered if I would ever see her again. Today, I wondered if she would be there when I walked through the halls. As I start my day, I begin to inquire about her. Is she still here? Is she still alive? How is she? They tell me she is still here, in body, but she's really gone. Any minute could be her last. I go about my busy day, tending to my patients and their needs. She begins to slip from my mind in the craziness of the day...

PURPOSE: Actinic keratoses (AKs) exist on a continuum with squamous cell carcinoma and can occur as sub-clinical and clinically visible lesions in cancerized fields on sun-damaged skin. Ingenol mebutate effectively treats AKs on areas up to 25 cm(2), but actinic keratosis can affect larger areas of skin. This trial evaluated systemic exposure and safety of ingenol mebutate gel on larger areas of skin under maximum use conditions. METHODS: Phase I, multicenter, open-label, uncontrolled, non-randomized trial...

Double layer two-dimensional electron systems at high perpendicular magnetic field are used to realize magnetic tunnel junctions in which the electrons at the Fermi level in the two layers have either parallel or antiparallel spin magnetizations. In the antiparallel case the tunnel junction, at low temperatures, behaves as a nearly ideal spin diode. At elevated temperatures the diode character degrades as long-wavelength spin waves are thermally excited. These tunnel junctions provide a demonstration that the spin polarization of the electrons in the N=1 Landau level at filling factors ν=5/2 and 7/2 is essentially complete, and, with the aid of an in-plane magnetic field component, that Landau level mixing at these filling factors is weak in the samples studied...

Fading Chen, Benjamin J Hall
Neurogenic differentiation factor 2 (NeuroD2) is a highly expressed transcription factor in the developing central nervous system. In newborn neurons, NeuroD2-mediated gene expression promotes differentiation, maturation, and survival. In addition to these early, cell-intrinsic developmental processes, NeuroD2 in post-mitotic neurons also regulates synapse growth and ion channel expression to control excitability. While NeuroD2 transactivation can be induced in an activity-dependent manner, little is known about how expression of NeuroD2 itself is regulated...

The mechanical behaviour of solid biological tissues has long been described using models based on classical continuum mechanics. However, the classical continuum theories of elasticity and viscoelasticity cannot easily capture the continual remodelling and associated structural changes in biological tissues. Furthermore, models drawn from plasticity theory are difficult to apply and interpret in this context, where there is no equivalent of a yield stress or flow rule. In this work, we describe a novel one-dimensional mathematical model of tissue remodelling based on the multiplicative decomposition of the deformation gradient...

BACKGROUND AND OBJECTIVES: Although arteriovenous fistulas have been found to be the most cost-effective form of hemodialysis access, the relative benefits of placing an arteriovenous fistula versus an arteriovenous graft seem to be least certain for older adults and when placed preemptively. However, older adults' life expectancy is heterogeneous, and most patients do not undergo permanent access creation until after dialysis initiation. We evaluated cost-effectiveness of arteriovenous fistula placement after dialysis initiation in older adults as a function of age and life expectancy...

BACKGROUND: Evidence associates various biometric and histological variables such as steatosis and absence of fibrosis as risk factors for post-operative pancreatic fistula (POPF) after pancreatoduodenectomy (PD). Following distal pancreatectomy (DP), the association between these factors and POPF is less clear. This study of patients, drawn from the same background population, undergoing PD or DP at a single centre is a comparative study of the risk factors for POPF after these two operations...

OBJECTIVE: Education scholarship can be conducted using a variety of methods, from quantitative experiments to qualitative studies. Qualitative methods are less commonly used in emergency medicine (EM) education research but are well-suited to explore complex educational problems and generate hypotheses. We aimed to review the literature to provide resources to guide educators who wish to conduct qualitative research in EM education. METHODS: We conducted a scoping review to outline: 1) a list of journals that regularly publish qualitative educational papers; 2) an aggregate set of quality markers for qualitative educational research and scholarship; and 3) a list of quality checklists for qualitative educational research and scholarship...
