Past attempts to identify the neural substrates of hand and finger imitation skills in the left hemisphere of the brain have yielded inconsistent results. Here, we analyse those associations in a large sample of 257 left hemisphere stroke patients. By introducing novel Bayesian methods, we characterise lesion symptom associations at three levels: the voxel-level, the single-region level (using anatomically defined regions), and the region-pair level. The results are inconsistent across those three levels and we argue that each level of analysis makes assumptions which constrain the results it can produce...

Despite knowledge about the profound effects of child abuse and neglect, we know little about how best to assess whether maltreated children should return home. The effectiveness of the New Orleans Intervention Model (NIM) is being tested in a randomized controlled trial where the comparison is social work 'services as usual.' The future trial results will tell us which approach produces the best outcomes for children; meanwhile qualitative process evaluation is generating intriguing findings about the perceived impact of NIM on decision-making about childrens' futures...

BACKGROUND/OBJECTIVES: Refeeding syndrome (RFS), a life-threatening medical condition, is commonly associated with acute or chronic starvation. While the prevalence of patients at risk of RFS in hospital reportedly ranges from 0 to 80%, the prevalence and types of patients who die as a result of RFS is unknown. We aimed to measure the prevalence rate and examine the case histories of patients who passed away with RFS listed as a cause of death. SUBJECTS/METHODS: Patients were eligible for inclusion provided their death occurred within a Queensland hospital...

In the context of medical three-dimensional (3D) printing, in addition to 3D reconstruction from cross-sectional imaging, graphic design plays a role in developing and/or enhancing 3D-printed models. A custom prototype modular 3D model of the liver was graphically designed depicting segmental anatomy of the parenchyma containing color-coded hepatic vasculature and biliary tree. Subsequently, 3D printing was performed using transparent resin for the surface of the liver and polyamide material to develop hollow internal structures that allow for passage of catheters and wires...

BACKGROUND: Likely due to the high level of strain exerted across the elbow during the throwing motion, elbow injuries are on the rise in baseball. To identify at-risk athletes and guide postinjury return-to-throw programs, a better understanding of the variables that influence elbow varus torque is desired. PURPOSE: To describe the within-subject relationship between elbow varus torque and arm slot and arm rotation in professional baseball pitchers. STUDY DESIGN: Descriptive laboratory study...

Using deprotonated forms of tridentate azo-containing pyridine-2-/pyrazine-2-carboxamide 2-[N-(2-phenylazo)carbamoyl]-pyridine/pyrazine, seven bis-ligand complexes of Fe(II)/Co(II) and Fe(III)/Co(III) have been synthesized. Molecular structures of six of them reveal that these six-coordinate complexes utilize all available donor sites of the ligands and assume M(II/III)N2(pyridine/pyrazine)N'2(amide)N''2(azo) coordination. Complexes of Fe(II) and Co(III) are diamagnetic and those of Fe(III) and Co(II) are paramagnetic (S = 1/2; room-temperature magnetic data and EPR spectra)...

M Oberst
The new treatment procedures of the German Statutory Accident Insurance (DGUV) have ramifications for the injury type procedure clinics (VAV) from medical, economic and structural aspects. Whereas the latter can be assessed as positive, the medical and economical aspects are perceived as being negative. Problems arise from the partially unclear formulation of the injury type catalogue, which results in unpleasant negotiations with the occupational insurance associations with respect to financial remuneration for services rendered...

The analysis of timing in human movements requires a reference with which timing can be quantified. In reactive movements this reference is given by the stimulus. However, many movements do not respond to such an external event. In throwing, for instance, the hand opening for release has to be timed to an acceleration of the throwing arm. A common approach to analyzing release-timing variability is to choose a landmark in the movement that is supposed to have a fixed temporal relation to the release. Such distinct landmarks, however, are not always well definable...

BACKGROUND: Hamstring autograft is a common graft choice when performing ulnar collateral ligament reconstruction (UCLR). PURPOSE/HYPOTHESIS: The purpose of this study was to survey Major League Baseball (MLB) team physicians and determine whether these physicians harvest the hamstring (semitendinosus or gracilis) from the drive leg (ipsilateral to surgical site) or landing leg (contralateral to surgical site) when performing UCLR on elite-level pitchers. The hypothesis was that the majority of surgeons harvest the hamstring from the drive leg when performing a UCLR...

Butyrate and niacin are produced by gut microbiota, however butyrate has received most attention for its effects on colonic health. The present study aimed at exploring the effect of niacin on experimental colitis as well as throwing some light on the ability of niacin to modulate angiogenesis which plays a crucial role of in the pathogenesis of inflammatory bowel disease. Rats were given niacin for 2 weeks. On day 8, colitis was induced by intrarectal administration of iodoacetamide. Rats were sacrificed on day 15 and colonic damage was assessed macroscopically and histologically...

The mechanistic foundations of performance trade-offs are clear: because body size and shape constrains movement, and muscles vary in strength and fibre type, certain physical traits should act in opposition with others (e.g. sprint versus endurance). Yet performance trade-offs are rarely detected, and traits are often positively correlated. A potential resolution to this conundrum is that within-individual performance trade-offs can be masked by among-individual variation in 'quality'. Although there is a current debate on how to unambiguously define and account for quality, no previous studies have partitioned trait correlations at the within- and among-individual levels...

Paracetamol (APAP) is one of the most widely used and popular over-the-counter analgesic and antipyretic drugs in the world when used at therapeutic doses. APAP overdose can cause severe liver injury, liver necrosis and kidney damage in human beings and animals. Many studies indicate that oxidative stress is involved in the various toxicities associated with APAP, and various antioxidants were evaluated to investigate their protective roles against APAP-induced liver and kidney toxicities. To date, almost no review has addressed the APAP toxicity in relation to oxidative stress...

Visually-guided action of tossing to a target allows examining coordination between mechanical information for maintaining posture while throwing and visual information for aiming. Previous research indicates that relationships between visual and mechanical information persist in tossing behavior long enough for mechanical cues to prompt recall of past visual impressions. Multifractal analysis might model the long-term coordinations among movement components as visual information changes. We asked 32 adult participants (6 female, 25 male, one not conforming to gender binary; aged M=19...

Cortical microcircuits are very complex networks, but they are composed of a relatively small number of stereotypical motifs. Hence one strategy for throwing light on the computational function of cortical microcircuits is to analyze emergent computational properties of these stereotypical microcircuit motifs. We are addressing here the question how spike-timing dependent plasticity (STDP) shapes the computational properties of one motif that has frequently been studied experimentally: interconnected populations of pyramidal cells and parvalbumin-positive inhibitory cells in layer 2/3...
