Wetlands in the region of Southern Ontario, Canada have declined substantially from their historic area. Existing regulations and programs have not abated this decline. However, reversing this trend by protecting or restoring wetlands will increase the supply of important ecosystem services. In particular, these actions will contribute to moderating the impacts of extreme weather predicted to result from climate change as well as reducing phosphorous loads in Lake Erie and ensuing eutrophication. Since the majority of land in the region is privately owned, landowners can play an important role...

Clinical observations suggest a complex relationship between human obesity and cardiovascular disease. Whilst abdominal (visceral) adiposity leads to deleterious metabolic disturbances, subcutaneous fat accumulation has a benign effect on cardiometabolic risk. Notably, an accumulating body of evidence paradoxically links increased body mass index with a better prognosis in patients with established cardiovascular disease, a finding that has been termed the 'obesity paradox'. While this is now acknowledged to be an epidemiological finding, a metabolically healthy obese group associated with low cardiovascular risk has also been identified...

Oxidized low density lipoprotein (oxLDL) induces macrophage activation, an event essential for atherosclerosis. Emerging evidence supports that epigenetic regulation plays important roles in macrophage activation and function. However, it remains unclear which epigenetic modulator is responsible for oxLDL-induced macrophage activation. Here, we identify for the first time KDM4A (JMJD2A) as an epigenetic modifying enzyme that controls oxLDL-induced pro-inflammatory M1 polarization of macrophages. OxLDL triggered M1 polarization of murine and human macrophages, characterized by expression of iNOS and robust production of inflammatory cytokines (e...

Various novel androgen receptor (AR) targeting drugs have been developed recently and have shown beneficial effects on survival in patients with metastatic castration-resistant prostate cancer (mCRPC). However, no consensus has been reached regarding which of these agents provides the most favorable oncological outcomes. Here, we aimed to compare the efficacy of novel AR-targeted agents by performing a network meta-analysis of randomized controlled trials (RCTs). We included eight RCTs for men with mCRPC treated with one of the AR targeting agents: abiraterone acetate, enzalutamide, or orteronel...

We have devised the composite procedures WG and WGh to unify the W1X and the (computationally more economical) G4(MP2)-6X protocols. The WG procedure employs a combination of MP2, MP2-F12, CCSD-F12b, and CCSD(T) to approximate the all-electron scalar-relativistic CCSD(T)/CBS energy. In addition, it incorporates features such as the scaling of the energy components and an empirical "higher-level-correction" term. The WGh protocol represents a somewhat more economical variant of WG with partial removal of diffuse functions...

RHO GTPases regulate cell migration, cell-cycle progression, and cell survival in response to extracellular stimuli. However, the regulatory effects of RHO GTPases in mesenchymal stromal cells (MSCs) are unclear. Herein, we show that CDC42 acts as an essential factor in regulating cell proliferation and also takes part in lipotoxic effects of palmitate in human umbilical cord Wharton's jelly derived MSCs (hWJ-MSCs). Cultured human bone marrow (hBM-MSCs), adipose tissue (hAD-MSCs), and umbilical cord Wharton's jelly (hWJ-MSCs) derived cells had varying pro-inflammatory cytokine secretion levels and cell death rates when treated by palmitate...

Millions of tons of sodium borates are used annually by global industries in diverse applications important to modern society. The Na2O-B2O3-H2O phase diagram in the 0-100 °C temperature range contains 13 unique hydrated crystalline sodium borates, including five important industrial products. Structures were previously reported for each of these except for that having the highest boron content, known as sodium enneaborate, Na4B18O29·11H2O or 2Na2O·9B2O3·11H2O (1). Here we report the single-crystal structure of 1, revealing the structural formula Na2[B8O11(OH)4]·B(OH)3·2H2O, and describe some of its properties and relationships to other sodium borates...

We review current findings associating socioeconomic status (SES), development of neurocognitive functions, and neurobiological pathways. A sizeable interdisciplinary literature was organized through a bifurcated developmental trajectory (BiDeT) framework, an account of the external and internal variables associated with low SES that may lead to difficulties with attention and learning, along with buffers that may protect against negative outcomes. A consistent neurocognitive finding is that low-SES children attend to information nonselectively, and engage in late filtering out of task-irrelevant information...

Enzyme-linked immunosorbent assay (ELISA) is widely used in medical diagnostics and fundamental biological research due to its high specificity and reproducibility. However, the traditional 96-well-plate based ELISA still suffers from several notable drawbacks, such as long assay time (4-6 hours), burdensome procedures and large sample/reagent volumes (∼100 μl), which significantly limit traditional ELISA's applications in rapid clinical diagnosis and quasi-real-time prognosis of some fast-developing diseases...

Cellular interactions in the tumor microenvironment influence neoplastic progression in pancreatic ductal adenocarcinoma. One underlying mechanism is the induction of the prognostically unfavorable epithelial-mesenchymal-transition-like tumor budding. Our aim is to explore the expression of microRNAs implicated in the regulation of tumor budding focusing on the microenvironment of the invasive front. To this end, RNA from laser-capture-microdissected material of the main tumor, tumor buds, juxta-tumoral stroma, tumor-remote stroma, and non-neoplastic pancreatic parenchyma from pancreatic cancer cases with (n=7) and without (n=6) tumor budding was analyzed by qRT-PCR for the expression of a panel of miRNAs that are known to be implicated in the regulation of epithelial-mesenchymal transition, including miR-21, miR-183, miR-200b, miR-200c, miR-203, miR-205, miR-210, and miR-217...

A hybrid vector of adeno-associated virus and phage (termed AAVP) has been introduced as a platform for systemic ligand-directed delivery of transgenes to tumors over the past decade. A series of studies have evaluated the AAVP platform for potential theranostic or purely therapeutic applications in several tumor models. Sufficient ligand-directed tumor targeting consistently resulted in specific molecular-genetic imaging and/or anti-tumor responses to 'suicide' transgene delivery. However, efforts to optimize transduction efficiency are still ongoing...

Background: Propolis, a resinous substance produced by the honeybee, has a wide spectrum of potent biological activities. However, anti-cancer activity of propolis obtained from Trigona sirindhornae, a new species of stingless bee, has not yet been reported. This study concerned cytotoxicity of propolis extracts from T. sirindhornae against two head and neck squamous cell carcinoma (HNSCC) cell lines. Materials and Methods: A dichloromethane extract of propolis (DMEP) was prepared generating 3 fractions: DMEP-A, DMEP-B, and DMEP-C...

BACKGROUND: There has been controversy as to whether the glyphosate resistance gene and/or glyphosate applied to glyphosate-resistant (GR) soybean affect the content of cationic minerals (especially Mg, Mn, and Fe), yield and amino acid content of GR soybean. A two-year field study (2013 and 2014) examined these questions at sites in Mississippi, USA. RESULTS: There were no effects of glyphosate, the GR transgene, or field crop history (for a field with both no history of glyphosate use versus one with a long history of glyphosate use) on grain yield...

Carbohydrate-binding modules (CBMs) are non-catalytic domains that are generally appended to carbohydrate-active enzymes. CBMs have a broadly conserved structure that allows recognition of a notable variety of carbohydrates, in both their soluble and insoluble forms, as well as in their alpha and beta conformations and with different types of bonds or substitutions. This versatility suggests a high functional plasticity that is not yet clearly understood, in spite of the important number of studies relating protein structure and function...

The use of sedative medications is commonplace in intensive care units (ICUs) and an invaluable clinical tool for the intensive care physician. Sedation for critically ill, mechanically ventilated patients provides an opportunity to reduce anxiety, discomfort as well as ventilator intolerance and dyssynchrony. Alpha-2 agonists in particular have become increasingly popular for use in the neurocritical care population due to their proposed effectiveness in facilitating examinations and procedures as well as reducing the need for adjunctive agents...

Maxwell S Barnish, Steve Turner
Evidence-based practice is an important component of health care service delivery. However, there is a tendency, embodied in tools such as Grades of Recommendation, Assessment, Development, and Evaluation, to focus principally on the classification of study design, at the expense of a detailed assessment of the strengths and limitations of the individual study. Randomized controlled trials (RCTs), and in particular the classical "explanatory" RCT, have a privileged place in the hierarchy of evidence. However, classical RCTs have substantial limitations, most notably a lack of generalizability, which limit their direct applicability to clinical practice implementation...

Approximately a fifth of ovarian carcinoma (OC) is associated with inherited germline mutations, most commonly in the DNA repair genes BRCA1 or BRCA2 (BRCA). BRCA1- and BRCA2-associated OCs have historically been described as a single subgroup of OC that displays a distinct set of characteristics termed the "BRCAness" phenotype. The hallmarks of this phenotype are superior clinical outcome and hypersensitivity to platinum-based chemotherapy and poly-(ADP-ribose) polymerase (PARP) inhibitors. However, growing evidence suggests that BRCA1- and BRCA2-associated OCs display distinct characteristics, most notably in long-term patient survival...

In the face of rapidly aging population, decreasing regional inequalities in population composition is one of the regional cohesion goals of the European Union. To our knowledge, no explicit quantification of the changes in regional population aging differentiation exist. We investigate how regional differences in population aging developed over the last decade and how they are likely to evolve in the coming three decades, and we examine how demographic components of population growth contribute to the process...
