BACKGROUND: Paediatric PCL injuries are rare but constitute a significant management challenge. We describe a novel approach to the surgical management of an 11-year-old boy who presented with persisting symptomatic instability following 18months of failed conservative therapy. METHODS: PCL reconstruction was performed using a physeal sparing, all-inside technique under fluoroscopic control. This avoids the potential for iatrogenic growth injury. A parentally donated hamstrings allograft was used to ensure adequate graft size, and reinforced using a non-elastic two millimetre braided suture...

The crystal structure of the title compound, C14H15BF2N2O2, which comprises a boron-dipyrromethene (BODIPY) backbone and a propionic acid group, has been determined at 100 K. The BODIPY fused-ring system is nearly planar, with a maximum deviation from the mean plane of 0.032 (2) Å. In the crystal, pairs of O-H⋯O hydrogen bonds connect the mol-ecules, forming inversion dimers. The dimers are linked via C-H⋯O hydrogen bonds, forming a tape along the a axis. The tapes are stacked along the c axis through C-H⋯F hydrogen bonds and π-π inter-actions...

Background: Social accountability (SA) comprises a set of mechanisms aiming to, on the one hand, enable users to raise their concerns about the health services provided to them (voice), and to hold health providers (HPs) accountable for actions and decisions related to the health service provision. On the other hand, they aim to facilitate HPs to take into account users' needs and expectations in providing care. This article describes the development of a SA intervention that aims to improve health services responsiveness in two health zones in the Democratic Republic of the Congo...

Elevated sphingosine 1-phosphate (S1P) is detrimental in Sickle Cell Disease (SCD), but the mechanistic basis remains obscure. Here, we report that increased erythrocyte S1P binds to deoxygenated sickle Hb (deoxyHbS), facilitates deoxyHbS anchoring to the membrane, induces release of membrane-bound glycolytic enzymes and in turn switches glucose flux towards glycolysis relative to the pentose phosphate pathway (PPP). Suppressed PPP causes compromised glutathione homeostasis and increased oxidative stress, while enhanced glycolysis induces production of 2,3-bisphosphoglycerate (2,3-BPG) and thus increases deoxyHbS polymerization, sickling, hemolysis and disease progression...

BACKGROUND: The Integral Theory (IT) states that urinary stress and urge symptoms mainly arise from lax suspensory ligaments, which are a consequence of altered collagen/elastin. Four important muscle groups (pubococcygeal muscle, levatorplate, longitudinal muscle of the anus, and the puborectalis muscle) are only able to guarantee the opening and closure mechanism of the bladder, the urethra and the anal tube if the suspensory ligaments are intact. The first practical application of the IT was the repair of the pubourethral ligament (PUL) known as tension-free vaginal tape (TVT)...

The purpose of tinnitus retraining therapy (TRT) is to induce habituation, first of the reaction to the tinnitus signal, and subsequently to habituate the perception of tinnitus itself. Habituation of sound is achieved through sound treatment which involves the use of low-level broadband noise mainly through noise maskers. Noise maskers are costly hence there is a need to find an alternate source of noise like MP3 and mobile phones. The goal of present study was to find out whether persons with tinnitus may be successfully treated with TRT using sound treatment from the noise presented through mobile phones...

This paper focuses on the construction and test results of Coil 2 that is part of a trio of nested coils composing the REBCO 800 MHz insert. Upon its completion, the REBCO 800 MHz insert will be placed in the bore of a 500 MHz low temperature superconducting (LTS) NMR magnet (L500) to form the MIT 1.3 GHz high-resolution NMR magnet. Coil 2 is a stack of 32 double pancake (DP) coils wound with 6-mm wide REBCO tape using the no-insulation (NI) technique. Each pancake is wound on a stainless steel inner supporting ring to prevent the collapsing of its crossover due to the external pressure exerted by the winding pack...

Control of parasitic gastroenteritis in cattle is typically based on group treatments with anthelmintics, complemented by grazing management, where feasible. However, the almost inevitable evolution of resistance in parasitic nematodes to anthelmintics over time necessitates a reappraisal of their use in order to reduce selection pressure. One such approach is targeted selective treatment (TST), in which only individual animals that will most benefit are treated, rather than whole groups of at-risk cattle. This study was designed to assess the feasibility of implementing TST on three commercial farms, two of which were organic...

RATIONALE: The detection and identification of human blood on crime-related items are of particular relevance to many investigations because shed blood can provide evidence of violent contact between individuals. However, for any detection and identification technique, specificity is a critical performance characteristic to assess; that is, whether the technique has the capability to differentiate between human blood (which usually is of relevance to a criminal investigation) and non-human blood (which usually would not be associated with a crime but may be detected incidentally)...

BACKGROUND/OBJECTIVES: Recent advances have extended anthropometry beyond flexible tape measurements to automated three-dimensional optical devices that rapidly acquire hundreds of body surface dimensions. Three new devices were recently introduced that share in common inexpensive optical cameras. The design, and thus potential clinical applicability, of these systems differ substantially leading us to critically evaluate their accuracy and precision. SUBJECTS/METHODS: 113 adult subjects completed evaluations by the three optical devices (KX-16 (16 stationary cameras), Proscanner (1 vertically oscillating camera), and Styku scanner (1 stationary camera)), air displacement plethysmography (ADP), dual-energy X-ray absorptiometry (DXA) and a flexible tape measure...
