Nanoscale engineering has traditionally adopted the chemical route of synthesis or opto-chemical techniques like lithography requiring large process times, expensive equipment and an inert environment. Directed self-assembly using evaporation of nanocolloidal droplet can be a potential low-cost alternative across various industries ranging from semiconductors to biomedical systems. It is relatively simple to scale and re-orient the evaporation driven internal flow field in an evaporating droplet which can direct dispersed matter into functional agglomerates...

Previous research has established a link between testosterone concentrations in males and their mating effort as it relates to their mate seeking behaviors. However, very little research has analyzed how variability in basal testosterone concentrations of males affects their mating effort once they have secured a romantic partner. In a sample of undergraduate men, the relationship between testosterone, intrasexual competitiveness, and mate retention behavior was examined. Results showed that higher basal testosterone predicted more self-reported mate retention effort...

BACKGROUND: Functional endoscopic sinus surgery is a common procedure performed within otolaryngology, but it carries potential for significant life-changing complications. It is therefore essential that trainees undergo adequate training. The European Working Time Directive has led to reduced operating time for the trainee surgeon. With variable access and the cost implications associated with cadaveric specimens, simulation can be an invaluable educational resource in surgical training...

Underwater visual census (UVC) is the most common approach for estimating diversity, abundance and size of reef fishes in shallow and clear waters. Abundance estimation through UVC is particularly problematic in species occurring at low densities and/or highly aggregated because of their high variability at both spatial and temporal scales. The statistical power of experiments involving UVC techniques may be increased by augmenting the number of replicates or the area surveyed. In this work we present and test the efficiency of an UVC method based on diver towed GPS, the Tracked Roaming Transect (TRT), designed to maximize transect length (and thus the surveyed area) with respect to diving time invested in monitoring, as compared to Conventional Strip Transects (CST)...

BACKGROUND: American Academy of Orthopaedic Surgeons (AAOS) Clinical Practice Guidelines for pediatric femoral shaft fractures indicate titanium elastic nails (TENs) for children 5 to 11 years old. Growing evidence suggests these fractures may also be treated with open or submuscular plating. The purpose of this study was to compare estimated blood loss (EBL), operative time, fluoroscopy time, cost, and subjective and objective pain scores between TENs and plating techniques used in 5- to 11-year-old children with midshaft femur fractures based on length stability...

BACKGROUND: Enhanced recovery (ERAS) protocols lead to expedited discharges and decreased cost. Bariatric centers have adopted such programs for safely discharging patients after sleeve gastrectomy (LSG) on the first postoperative day (POD1). Despite pathways, some bariatric patients cannot be discharged on POD1. METHODS: Retrospective review of patients undergoing LSG, between 2013 through 2016, in a center of excellence utilizing a standardized enhanced recovery pathway...

Understanding the potential for organisms to tolerate thermal stress through physiological or evolutionary responses is crucial given rapid climate change. Although climate models predict increases in both temperature mean and variance, such tolerances are typically assessed under constant conditions. We tested the effects of temperature variability during development on male fitness in the rainforest fly Drosophila birchii, by simulating thermal variation typical of the warm and cool margins of its elevational distribution, and estimated heritabilities and genetic correlations of fitness traits...

PURPOSE: Nearly 12 million children and adolescents in sub-Saharan Africa have lost one or both parents to AIDS. Within sub-Saharan Africa, Uganda has been greatly impacted, with an estimated 1.2 million orphaned children, nearly half of which have experienced parental loss due to the epidemic. Cost-effective and scalable interventions are needed to improve developmental outcomes for these children, most of whom are growing up in poverty. This article examines the direct impacts and cost-effectiveness of a savings-led family economic empowerment intervention, Bridges to the Future, that employed varying matched savings incentives to encourage investment in Ugandan children orphaned by AIDS...

BACKGROUND: Epilepsy is a common neurological condition with a worldwide prevalence of around 1%. Approximately 60% to 70% of people with epilepsy will achieve a longer-term remission from seizures, and most achieve that remission shortly after starting antiepileptic drug treatment. Most people with epilepsy are treated with a single antiepileptic drug (monotherapy) and current guidelines from the National Institute for Health and Care Excellence (NICE) in the United Kingdom for adults and children recommend carbamazepine or lamotrigine as first-line treatment for partial onset seizures and sodium valproate for generalised onset seizures; however a range of other antiepileptic drug (AED) treatments are available, and evidence is needed regarding their comparative effectiveness in order to inform treatment choices...

Biomedical facilities across the nation and worldwide aim to develop cost-effective methods for the reproductive management of macaque breeding groups, typically by housing macaques in large, multi-male multi-female social groups that provide monkey subjects for research as well as appropriate socialization for their psychological well-being. One of the most difficult problems in managing socially housed macaques is their propensity for deleterious aggression. From a management perspective, deleterious aggression (as opposed to less intense aggression that serves to regulate social relationships) is undoubtedly the most problematic behavior observed in group-housed macaques, which can readily escalate to the degree that it causes social instability, increases serious physical trauma leading to group dissolution, and reduces psychological well-being...
