Towards the integration of rules and ontologies in the Semantic Web, we propose a combination of logic programming under the answer set semantics with the description logics SHIF(D) and SHOIN (D), which underly the Web ontology languages OWL Lite and OWL DL, respectively. This combination allows for building rules on top of ontologies but also, to a limited extent, building ontologies on top of...
Experimental models and observational studies suggest that homocysteine-lowering therapy with folic acid (FA) may prevent cardiovascular disease (CVD). However, FA also stimulates cell proliferation and might promote progression of atherosclerosis. Our objectives were to perform a meta-analysis of FA supplementation trials on CVD events and to explore a potential interaction between FA suppleme...
Seed dormancy removal by cold stratification is accompanied by the development of gluconeogenic competence. Although hydrogen cyanide can stimulate the germination of many herbaceous dormant seeds and increase gluconeogenesis in long term, its short-term effects on sugar metabolism require further investigation. Accordingly, an experiment in the form of complete randomized design was carried ou...
BACKGROUND Hyperglycemia is an independent predictor of adverse outcomes during hospitalization. In patients who have pneumonia, significant hyperglycemia is associated with poor outcomes. This study evaluates the interaction of the degree of hyperglycemia and complication rates stratified by age in non-critically ill patients admitted to the hospital for care of community-acquired pneumonia. ...
Spontaneous canine oral melanoma (COM) is a highly metastatic cancer, resistant to chemotherapy, and can serve as a model for cancer immunotherapy. Liposome-encapsulated muramyl tripeptide-phosphatidylethanolamine (L-MTP-PE) can activate the tumoricidal activity of the monocyte-macrophage system following i.v. injection. The objective of these studies was to evaluate the therapeutic effectivene...
BACKGROUND Previous nested case-control studies suggest that a prediagnostic biomarker of allergy, IgE, is inversely associated with the risk of glioma, but these findings are inconsistent. The purpose of our study was to assess this association and determine how long before glioma diagnosis it may be observed. METHODS We conducted a nested case-control study using serum specimens from the Ja...
We visited 51 lakes in Costa Rica as part of a broad-based survey to document their physical and chemical characteristics and how these relate to the mode of formation and geographical distribution of the lakes. The four oxbow lakes were low in elevation and tended to be turbid, high in conductivity and CO2, but low in dissolved O2; one of these, L. Gandoca, had a hypolimnion essentially compos...
Multiple herbicide-resistant kochia [ Bassia scoparia (L.) A.J. Scott] is a growing weed management concern for farmers in the Canadian prairies. A randomized–stratified survey of 319 sites Alberta was conducted 2021 to determine frequency and incidence glyphosate, fluroxypyr, dicamba resistance samples four nine years after previous rounds surveys. Kochia exhibiting were found at 78%, 44%, 28%...
