Jamun fruit comprises of seed and thick pulp. The pectin-protein bond of the thick pulp creates difficulty in making juice. Clear Jamun juice is not available in the market, so there is a need for extraction of juice with maximum yield. The goal of this research is to obtain high yield of clarified juice with the help of Pectinase (Aspergillus aculeatus) enzyme. The study was conducted at different enzyme concentration (0.01-0.1%), time duration (40-120 min), and temperature (30-50 °C). Various physical and chemical parameters, such as yield, turbidity, viscosity, clarity, colour, polyphenol, protein, TSS, and total solid, were measured as dependent variables...

Arash Barfar, Balaji Padmanabhan
In a recent article by Barfar and Padmanabhan (2015), we demonstrated how television viewership data could predict presidential election outcomes in the United States. In this article, we examine predictive models using a snapshot of Nielsen's national data on television viewership. The study is conducted with high-dimensional low sample size (HDLSS) data, whereby we conduct a comparative analysis with and without feature reduction on the data from the 2012 elections. We find that simple "single-show models" often provided more insights and predictive accuracies than models from feature reduction...

RATIONALE: Amiodarone is reported to cause hepato and pulmonary toxicity in humans, which has been envisaged to be due to formation of its reactive metabolites, essentially based on its structural similarity to benzbromarone, a drug withdrawn from the market due to reasons of similar hepatotoxicity. Therefore, the purpose of this study was to detect glutathione conjugates of amiodarone and its reactive diquinone metabolites in rat bile using mass spectrometry tools. METHODS: Wistar rats were dosed orally with an amiodarone suspension and bile was collected via bile duct cannulation followed by solid-phase extraction, protein precipitation and centrifugation...

In our response, we review and address the comments on our target article made in the 25 commentaries. First, we review and discuss the commentaries that recognized the value of our approach, accepted the main premises and conclusions of our target article, and suggested further avenues for research on attractiveness-related biases. We then respond to commentators who either misinterpreted some parts of our target article or made statements with which we disagree. These commentaries provided us with an opportunity to clarify some aspects of our target article, for example, the fact that we address both the functional significance of attractiveness-related biases and their underlying mechanisms...

Enrichetta Ravina
Labor market and real-life studies were not designed to discriminate between evolutionary and taste-based and stereotype explanations for the beauty premium, have too many confounding effects, and lack crucial information. Smaller-stake and experimental studies provide more compelling evidence in favor of mating motives and suggest the direction of future research for the economists' field studies.

Christopher Y Olivola, Alexander Todorov
The influence of appearances goes well beyond physical attractiveness and includes the surprisingly powerful impact of "face-ism" - the tendency to stereotype individuals based on their facial features. A growing body of research has revealed that these face-based social attributions bias the outcomes of labor markets and experimental economic games in ways that are hard to explain via evolutionary mating motives.

REVIEW
Cameron P Peace
Crops of the Rosaceae family provide valuable contributions to rural economies and human health and enjoyment. Sustained solutions to production challenges and market demands can be met with genetically improved new cultivars. Traditional rosaceous crop breeding is expensive and time-consuming and would benefit from improvements in efficiency and accuracy. Use of DNA information is becoming conventional in rosaceous crop breeding, contributing to many decisions and operations, but only after past decades of solved challenges and generation of sufficient resources...

Max K Shepherd, Elliott J Rouse
Individuals with post-stroke hemiparesis often have difficulty standing out of a chair. One way to potentially improve sit-to-stand is to provide knee extension assistance using a powered knee exoskeleton. An exoskeleton providing unilateral, partial assistance during sit-to-stand would need to be torque-controllable. There are no knee exoskeletons on the market suitable for conducting experiments assisting stroke patients with sit-to-stand, so to enable such experiments a research device was developed. The purpose of this report is to present the design of a novel knee exoskeleton actuator that uses a fiberglass leaf spring in series to improve torque-controllability, and present a characterization of the actuator performance...

Ghareb M Soliman
Invasive fungal infections are becoming a major health concern in several groups of patients leading to severe morbidity and mortality. Moreover, cutaneous fungal infections are a major cause of visits to outpatient skin clinics. Despite the availability of several effective agents in the antifungal drug arena, their therapeutic outcome is less than optimal due to limitations related to drug physicochemical properties and toxicity. For instance, poor aqueous solubility limits the formulations options and efficacy of several azole antifungal drugs while toxicity limits the benefits of many other drugs...

CONTEXT: The proportion of patients disenrolling from hospice prior to death has increased over the decade with significant variations across hospice types and regions. Such trends have raised concerns about live disenrollment's effect on care quality. Live disenrollment may be driven by factors other than patient preference and may create discontinuities in care, disrupting ongoing patient-provider relationships. Researchers have not explored when and how providers make this decision with patients...

Linda Papa, Kevin K W Wang
Research in blood-based traumatic brain injury (TBI) biomarkers has imploded over the last two decades and continues to grow at an unwavering pace. Commercialization of these biomarkers is ongoing, with a number of companies seeking FDA approval to market their test for clinical application. Although there are many papers being published, many lack the rigorous reporting required to adequately evaluate these markers for clinical use. Too often, there are inadequate sample sizes, inappropriate control groups and outcome measures, variable definitions of TBI, inconsistencies in when samples are drawn relative to time of injury, variability in how samples are processed and performance characteristics of the assays themselves are rarely known or poorly described...

Lei Mou, Xingyu Jiang
Conventional immunoassays suffer from at least one of these following limitations: long processing time, high costs, poor user-friendliness, technical complexity, poor sensitivity and specificity. Microfluidics, a technology characterized by the engineered manipulation of fluids in channels with characteristic lengthscale of tens of micrometers, has shown considerable promise for improving immunoassays that could overcome these limitations in medical diagnostics and biology research. The combination of microfluidics and immunoassay can detect biomarkers with faster assay time, reduced volumes of reagents, lower power requirements, and higher levels of integration and automation compared to traditional approaches...

BACKGROUND: Worldwide, in the absence of standard pediatric prescribing information, clinicians often use medicines in children in a dosage form or for an indication that has not been approved for use. Inadequate clinical trials increase exposure to drugs that lack safety-efficacy data in pediatric population. Hence, off-label and unlicensed drug use must be regarded as a patient safety-issue that is known to be associated with increased risks of adverse drug reactions apart from under- or over-dosing due to lack of pharmacokinetic data...

Research in clinical pharmacology covers a wide range of experiments, trials and investigations: clinical trials, systematic reviews and meta-analyses of drug usage after market approval, the investigation of pharmacokinetic-pharmacodynamic relationships, the search for mechanisms of action or for potential signals for efficacy and safety using biomarkers. Often these investigations are exploratory in nature, which has implications for the way the data should be analysed and presented. Here we summarize some of the statistical issues that are of particular importance in clinical pharmacology research...

BACKGROUND: Total hip arthroplasty (THA) costs are a source of great interest in the currently evolving health care market. The initiation of a bundled payment system has led to further research into costs drivers of this commonly performed procedure. One aspect that has not been well studied is the effect of comorbidities on the reimbursements of THA. The purpose of this study was to determine if common medical comorbidities affect these reimbursements. METHODS: A retrospective, level of evidence III study was performed using the PearlDiver supercomputer to identify patients who underwent primary THA between 2007 and 2015...
