Dengue virus (DENV) is the causative agent of dengue fever and dengue hemorrhagic fever. The virus is endemic in over 120 countries, causing over 350 million infections per year. Dengue vaccine development is challenging because of the need to induce simultaneous protection against four antigenically distinct DENV serotypes and evidence that, under some conditions, vaccination can enhance disease due to specific immunity to the virus. While several live-attenuated tetravalent dengue virus vaccines display partial efficacy, it has been challenging to induce balanced protective immunity to all 4 serotypes...

More than 520 soil samples were surveyed for species of the mycoparasitic zygomycete genus Syncephalis using a culture-based approach. These fungi are relatively common in soil using the optimal conditions for growing both the host and parasite. Five species obtained in dual culture are unknown to science and are described here: (i) S. digitata with sporangiophores short, merosporangia separate at the apices, simple, 3-5 spored; (ii) S. floridana, which forms galls in the host and has sporangiophores up to 170 µm long with unbranched merosporangia that contain 2-4 spores; (iii) S...

Prader-Willi Syndrome (PWS) is caused by a genetic imprinting abnormality resulting from the lack of expression of the paternal genes at 15q11-q13. Intellectual disability, low muscle tone, and life-threatening hyperphagia are hallmarks of the phenotype. The need for the Heimlich maneuver, death from choking, and pulmonary infection occur in a disproportionally high number of persons with PWS. The widely held belief is that eating behaviors are responsible for choking and aspiration; yet, no investigation had sought to determine if swallowing impairments were present in persons with PWS...

BACKGROUND: Postburn axillary contractures are common and significantly impact quality of life. Simple release combined with split thickness skin grafting necessitates a donor site, requires immobilization, and may result in poor functional outcome. Common methods of adjacent tissue rearrangement are not well designed to treat broad linear contractures. Flaps from the back, flank, or arm can be used, but may come with significant donor site morbidity. We demonstrate the use of the STARplasty, a novel adjacent tissue rearrangement initially developed to treat neosyndactyly, as a useful reconstructive option for the release of Kurtzman type 1 posterior or anterior axillary contractures...

Child and adolescent trauma exposure is prevalent, with trauma exposure-related symptoms, including posttraumatic stress, depressive, and anxiety symptoms often causing substantial impairment. This article updates the evidence base on psychosocial treatments for child and adolescent trauma exposure completed for this journal by Silverman et al. (2008). For this review, we focus on 37 studies conducted during the seven years since the last review. Treatments are grouped by overall treatment family (e.g., cognitive behavioral therapy), treatment modality (e...

One of the central challenges of transplantation is the development of alloreactivity despite the use of multi-agent immunoprophylaxis. Effective control of this immune-suppression-resistant T cell activation represents one of the key unmet needs in the fields of both solid organ and hematopoietic stem cell transplant (HCT). To address this unmet need, we have used a highly-translational non-human primate model to interrogate the transcriptional signature of T cells during Breakthrough Acute GVHD that occurs in the setting of clinically-relevant immune suppression and compared this to the Hyperacute GVHD, that develops in unprophylaxed or sub-optimally prophylaxed transplant recipients...

There is demand for non-DMSO cryoprotective agents that maintain cell viability without causing poor post thaw function or systemic toxicity. The focus of this investigation involves expanding our understanding of multicomponent osmolyte solutions and their ability to preserve cell viability during freezing. Controlled cooling rate freezing, Raman microscopy, and differential scanning calorimetry (DSC) were utilized to evaluate the differences in recovery and ice crystal formation behavior for solutions containing multiple cryoprotectants including sugars, sugar alcohols, and small molecule additives...

The interactions of 8-hydroxybenzo[b]quinolizinium and 9-hydroxy-benzo[b]quinolizinium with DNA are investigated in detail. Specifically, spectro¬photometric and spectrofluorimetric titrations, thermal DNA-de¬na¬turation experiments as well as CD- and LD-spectroscopic ana¬lysis show that a pH shift by just one or two orders of magnitude has a significant impact on the interactions of the acidic ligands with the nucleic acid. Both ligands bind with high affinity to DNA at pH = 6 (Kb ≈ 105 M-1). At pH = 7 or 8, however, the binding interactions are much weaker because of the formation of the corresponding charge neutral conjugate bases whose affinity to DNA is reduced due to the resulting lack of a positive charge...

Bottom-up evolutionary approaches, including geographically-explicit population genomic analyses, have the power to reveal the mechanistic basis of adaptation. Here we conduct a population genomic analysis in the model legume, Medicago truncatula, in order to characterize population genetic structure and identify symbiosis-related genes showing evidence of spatially-variable selection. Using RAD-seq, we generated over 26,000 SNPs from 191 accessions from within three regions of the native range in Europe. Results from STRUCTURE analysis identify 5 distinct genetic clusters with divisions that separate east and west regions in the Mediterranean basin...

This review focuses on important aspects of applying physisorption for the pore structural characterization of hierarchical materials such as mesoporous zeolites. During the last decades major advances in understanding the adsorption and phase behavior of fluids confined in ordered nanoporous materials have been made, which led to major progress in the physisorption characterization methodology (summarized in the 2015 IUPAC report on physisorption characterization). Here we discuss progress and challenges for the physisorption characterization of nanoporous solids exhibiting various levels of porosity from micro- to macropores...

This study examined the effect of time pressure on face-matching accuracy. Across two experiments, observers decided whether pairs of faces depict one person or different people. Time pressure was exerted via two additional displays, which were constantly updated to inform observers on whether they were on track to meet or miss a time target. In this paradigm, faces were matched under increasing or decreasing (Experiment 1) and constant time pressure (Experiment 2), which varied from 10 to 2 seconds. In both experiments, time pressure reduced accuracy, but the point at which this declined varied from 8 to 2 seconds...

BACKGROUND: Eating disorders such as anorexia nervosa and bulimia nervosa affect overall and reproductive health and may also affect breast cancer risk. We studied the association between self-reported eating disorders and breast cancer risk in a prospective cohort study. METHODS: In 2003-2009, the Sister Study enrolled women aged 35-74 who had a sister with breast cancer but had never had it themselves. Using data from 47,813 women, we estimated adjusted hazard ratios (HR) and 95% confidence intervals for the association between eating disorders and invasive breast cancer over a median of 5...

BACKGROUND: Developing a healthcare delivery system that is more responsive to the future challenges of an aging population is a priority in Canada. The World Health Organization acknowledges the need for knowledge translation frameworks in aging and health. Knowledge brokering (KB) is a specific knowledge translation approach that includes making connections between people to facilitate the use of evidence. Knowledge gaps exist about KB roles, approaches, and guiding frameworks. The objective of the scoping review is to identify and describe KB approaches and the underlying conceptual frameworks (models, theories) used to guide the approaches that could support healthy aging...
