Models of Care (MoCs) for injured workers in the compensation environment recommend adoption of biopsychosocial management approaches. Still, widespread dominance of biomedical constructs at the system, organisational and individual levels of the compensation system prevails, contributing to suboptimal management practices and outcomes for injured workers. Efforts to implement contemporary MoCs in the compensation environment show some promise in improving outcomes. Areas of promise at the organisational level, particularly in the workplace, and at the system level are discussed...

Molecularly imprinted polymer (MIP) synthetic receptors have proposed and applied applications in chemical extraction, sensors, assays, catalysis, targeted drug delivery, and direct inhibition of harmful chemicals and pathogens. However, they rely heavily on effective design for success. An algorithm has been written which mimics radical polymerization atomistically, accounting for chemical and spatial discrimination, hybridization, and geometric optimization. Synthetic ephedrine receptors were synthesized in silico to demonstrate the accuracy of the algorithm in reproducing polymers structures at the atomic level...

Several studies have suggested that large-diameter (>25 μm) arterio-venous shunt pathways exist in the lungs of rats, dogs, and humans. We investigated the nature of these pathways by infusing specific-diameter fluorescent latex particles (4, 7, 15, 30, or 50 μm) into isolated, ventilated rat lungs perfused at constant pressure. All lungs received the same mass of latex (5 mg), which resulted in infused particle numbers that ranged from 1.7 × 10(7) 4 μm particles to 7.5 × 10(4) 50 μm particles...

Transcriptomes of two switchgrass genotypes representing the upland and lowland ecotypes will be key tools in switchgrass genome annotation and biotic and abiotic stress functional genomics. Switchgrass (Panicum virgatum L.) is an important bioenergy feedstock for cellulosic ethanol production. We report genome-wide transcriptome profiling of two contrasting tetraploid switchgrass genotypes, VS16 and AP13, representing the upland and lowland ecotypes, respectively. A total of 268 million Illumina short reads (50 nt) were generated, of which, 133 million were obtained in AP13 and the rest 135 million in VS16...

OBJECTIVES: Pulmonary hypertension has been reported to occur in a considerable proportion of patients with end-stage renal disease. End-stage renal disease affects the health-related quality of life of patients. There is a lack of specific information on the relation between pulmonary hypertension and health-related quality of life in patients with end-stage renal disease in the literature. We aimed to evaluate this relation in patients undergoing hemodialysis. MATERIALS AND METHODS: This prospective case-control study included 68 patients treated with hemodialysis and 30 healthy participants as controls...

Patients with aneurysmal subarachnoid hemorrhage (a-SAH) show long-term fatigue and face difficulties in resuming daily physical activities. Impaired muscle strength, especially of the lower extremity, impacts the performance of daily activities and may trigger the onset of fatigue complaints. The present study evaluated knee muscle strength and fatigue in patients with a-SAH. This study included 33 patients, 6 months after a-SAH, and 33 sex-matched and age-matched healthy controls. Isokinetic muscle strength of the knee extensors and flexors was measured at 60 and 180°/s...

Disruptive, damaging ultra-rare variants in highly constrained genes are enriched in individuals with neurodevelopmental disorders. In the general population, this class of variants was associated with a decrease in years of education (YOE). This effect was stronger among highly brain-expressed genes and explained more YOE variance than pathogenic copy number variation but less than common variants. Disruptive, damaging ultra-rare variants in highly constrained genes influence the determinants of YOE in the general population...

The rational design of molecularly imprinted polymers (MIPs) has been a major contributor to their reputation as "plastic antibodies" - high affinity robust synthetic receptors which can be optimally designed, and produced for a much reduced cost than their biological equivalents. Computational design has become a routine procedure in the production of MIPs, and has led to major advances in functional monomer screening, selection of cross-linker and solvent, optimisation of monomer(s)-template ratio and selectivity analysis...

Novel molecularly imprinted polymer nanoparticles (nanoMIPs) were designed for endotoxin from Escherichia coli 0111:B4, using computational modeling. The screening process based on binding energy between endotoxin and each monomer was performed with 21 commonly used monomers, resulting in the selection of itaconic acid, methacrylic acid and acrylamide as functional monomers due to their strong binding interaction with the endotoxin template. The nanoMIPs were successfully synthesized with functional groups on the outer surface to aid in the immobilization onto sensor surface...

BACKGROUND: Both osteoarthritis (OA) and cardiovascular diseases (CVD) are prevalent conditions which often co-exist. Vascular involvement in the pathogenesis of these diseases, as well as increased cardiovascular risk in OA patients give occasion to investigate arterial stiffness in OA. The aim of this study was to establish associations between OA and arterial stiffness. METHODS: The characteristics of arterial stiffness were measured with Sphygmocor and HDI devices in 48 patients (age 63 ± 7 years (mean ± SD)) with end-stage OA awaiting knee and hip replacement and in 49 age and gender matched controls (61 ± 7 years)...
