Following decades of ecologic and economic impacts from a growing list of nonindigenous and invasive species, government and management entities are committing to systematic early- detection monitoring (EDM). This has reinvigorated investment in the science underpinning such monitoring, as well as the need to convey that science in practical terms to those tasked with EDM implementation. Using the context of nonindigenous species in the North American Great Lakes, this article summarizes the current scientific tools and knowledge - including limitations, research needs, and likely future developments - relevant to various aspects of planning and conducting comprehensive EDM...

Bootstrap methods are widely used in statistics, and bootstrapping of residuals can be especially useful in the regression context. However, difficulties are encountered extending residual resampling to regression settings where residuals are not identically distributed (thus not amenable to bootstrapping)-common examples including logistic or Poisson regression and generalizations to handle clustered or multivariate data, such as generalised estimating equations. We propose a bootstrap method based on probability integral transform (PIT-) residuals, which we call the PIT-trap, which assumes data come from some marginal distribution F of known parametric form...

Machine learning is becoming a popular and important approach in the field of medical research. In this study, we investigate the relative performance of various machine learning methods such as Decision Tree, Naïve Bayes, Logistic Regression, Logistic Model Tree and Random Forests for predicting incident diabetes using medical records of cardiorespiratory fitness. In addition, we apply different techniques to uncover potential predictors of diabetes. This FIT project study used data of 32,555 patients who are free of any known coronary artery disease or heart failure who underwent clinician-referred exercise treadmill stress testing at Henry Ford Health Systems between 1991 and 2009 and had a complete 5-year follow-up...

Even decades after the discovery of Cadmium (Cd) toxicity, research on this heavy metal is still a hot topic in scientific literature: as we wrote this review, more than 1440 scientific articles had been published and listed by the PubMed.gov website during 2017. Cadmium is one of the most common and harmful heavy metals present in our environment. Since pregnancy is a very particular physiological condition that could impact and modify essential pathways involved in the handling of Cd, the prenatal life is a critical stage for exposure to this non-essential element...

Alzheimer's disease (AD) is a chronically progressive neurodegenerative disease highly correlated to aging. Whether AD originates by targeting a localized brain area and propagates to the rest of the brain across disease-severity progression is a question with an unknown answer. Here, we aim to provide an answer to this question at the group-level by looking at differences in diffusion-tensor brain networks. In particular, making use of data from Alzheimer's Disease Neuroimaging Initiative (ADNI), four different groups were defined (all of them matched by age, sex and education level): G1 (N1 = 36, healthy control subjects, Control), G2 (N2 = 36, early mild cognitive impairment, EMCI), G3 (N3 = 36, late mild cognitive impairment, LMCI) and G4 (N4 = 36, AD)...

It has been demonstrated that the biological effector of mesenchymal stem/stromal cells (MSCs) is their secretome, which is composed of a heterogeneous pool of bioactive molecules, partially enclosed in extracellular vesicles (EVs). Therefore, the MSC secretome (including EVs) has been recently proposed as possible alternative to MSC therapy. The secretome can be considered as a protein-based biotechnological product, it is probably safer compared with living/cycling cells, it presents virtually lower tumorigenic risk, and it can be handled, stored and sterilized as an Active Pharmaceutical/Principle Ingredient (API)...

Around the world, psychiatrists are in exceptionally short supply. The majority of mental health treatment is delivered in primary care. In the United States, the Collaborative Care Model (CCM) addresses the shortfall of psychiatrists by providing indirect consultation in primary care. A Cochrane meta-analysis affirms the efficacy this model for depression and anxiety. However, our experience with the CCM suggests that most patients referred for consultation have problems far more complex than simple depression and anxiety...

Natural plant microbiomes are abundant and have a remarkably robust composition, both as epiphytes on the plant surface and as endophytes within plant tissues. Microbes in the former "habitat" face limited nutrients and harsh environmental conditions, while those in the latter likely lead a more sheltered existence. The most populous and diverse of these microbiomes are associated with the zone around the plant roots, commonly referred to as the rhizosphere. A majority of recent studies characterize these plant-associated microbiomes by community profiling of bacteria and fungi, using amplicon-based marker genes and next-generation sequencing (NGS)...

DNA methylation is the most important epigenetic change affecting gene expression in plants grown under normal as well as under stress conditions. Therefore, researchers study differential DNA methylation under distinct environmental conditions and their relationship with transcriptome abundance. Up to date, more than 25 methods and techniques are available to detect DNA methylation based on different principles. Bisulfite sequencing method is considered as a gold standard since it is able to distinguish 5-methylcytosine from cytosine using the bisulfite treatment...

Lipid droplets are cytoplasmic organelles that store neutral lipids and are critically important for energy metabolism. Their function in energy storage is firmly established and increasingly well characterized. However, emerging evidence indicates that lipid droplets also play important and diverse roles in the cellular handling of lipids and proteins that may not be directly related to energy homeostasis. Lipid handling roles of droplets include the storage of hydrophobic vitamin and signaling precursors, and the management of endoplasmic reticulum and oxidative stress...

The cardiac sarco/endoplasmic reticulum Ca(2+)-dependent ATPase 2a (SERCA2a) plays a central role in Ca(2+) handling within cardiomyocytes and is negatively regulated by phospholamban (PLN), a sarcoplasmic reticulum (SR) membrane protein. The activation of SERCA2a, which has been reported to improve cardiac dysfunction in heart failure, is a potential therapeutic approach for heart failure. Therefore, we developed a novel small molecule, compound A and characterized it both in vitro and in vivo. Compound A activated the Ca(2+)-dependent ATPase activity of cardiac SR vesicles but not that of skeletal muscle SR vesicles that lack PLN...

BACKGROUND: Intraoperative instrument recounts are performed to avoid retained foreign surgical items. These additional counts, however, beget risks of their own, including prolonged operative times, exposure to radiation, and increased cost. Our study aimed to identify factors that increase the likelihood of instrument recounts during plastic surgery procedures, and use our findings to guide potential solutions for preventing unnecessary recounts across all surgical fields. STUDY DESIGN: This is a retrospective review of all plastic surgical cases in the main operating setting at New York University Langone Medical Center (NYULMC) between March 2014 and February 2015...

To rapidly identify novel PPARγ ligands, a robust binding assay amenable to high-efficiency screening toward PPARγ would be desirable. In this study, a new PPARγ assembled on DNA origami (PPARγ/DNA origami) biochromatography drug screening model was constructed and evaluated. The method was used to screen active ingredients acted on PPARγ from the total ginsenosides. The total ginsenosides were handled on this biochromatography column by HPLC. The collected retention fraction from the biochromatography column was analyzed by HPLC and HPLC/MS...

The life of an organism requires the assistance of an unlikely process: programmed cell death. Both development and the maintenance of homeostasis result in the production of superfluous cells that must eventually be disposed of. Furthermore, programmed cell death can also represent a defense mechanism; for example, by depriving pathogens of a replication niche. The responsibility of handling these dead cells falls on phagocytes of the immune system, which surveil their surroundings for dying or dead cells and efficiently clear them in a quiescent manner...

The use of cyanuric acid as a biomarker for ingestion of swimming pool water may lead to quantitative knowledge of the volume of water ingested during swimming, contributing to a better understanding of disease resulting from ingestion of environmental contaminants. When swimming pool water containing chlorinated cyanurates is inadvertently ingested, cyanuric acid is excreted quantitatively within 24 h as a urinary biomarker of ingestion. Because the volume of water ingested can be quantitatively estimated by calculation from the concentration of cyanuric acid in 24 h urine samples, a procedure for preservation, cleanup, and analysis of cyanuric acid was developed to meet the logistical demands of large scale studies...
