Price transmission is a critically important issue that affects market enlargement and the unification of Canadian–U.S. agriculture. This study adopts alternative frameworks to examine the nature of cross-border integration in selected meat and livestock markets. The aim is to determine the extent to which selected meat and livestock markets transmit price signals across the international borde...

Choline plays a lipotropic role in lipid metabolism as an essential nutrient. In this study, we investigated the effects of choline (5, 35 and 70 μM) on DNA methylation modifications, mRNA expression of the critical genes and their enzyme activities involved in hepatic lipid metabolism, mitochondrial membrane potential (Δψm) and glutathione peroxidase (GSH-Px) in C3A cells exposed to excessive ...

BACKGROUND Paraoxonase-1 (PON1) activity is suggested to be altered in individuals infected with human immunodeficiency virus type-1 (HIV-1). We investigated PON1 activity in individuals receiving different regimens of highly active antiretroviral therapy (HAART). METHODS PON1 activity was evaluated in 91 HIV-1 seronegative and 624 HIV-1 infected individuals (115 were not undergoing therapy (...

A tooth enamel electron spin resonance (ESR) dosimetry study was carried out with the purpose of obtaining the individual absorbed radiation doses of population from settlements in the Semipalatinsk region of Kazakhstan, which was exposed to radioactive fallout traces from nuclear explosions in the Semipalatinsk Nuclear Test Site and Lop Nor test base, China. Most of the settlements are located...

Scatter search is a population-based method that has recently been shown to yield promising outcomes for solving combinatorial and nonlinear global optimization problems. Based on formulations originally proposed in the 1960s for combining decision rules and problem constraints, such as in generating surrogate constraints, scatter search uses strategies for combining solution vectors that have ...

introduction: application of light transmitting posts to restore greatly damaged endodontically treated teeth has been increased. it is suspected that light intensity decreases as it passes throughout different materials. this can reduce the degree of conversion required for adequate bond strength throughout the length of these posts. the objective of this study was to evaluate the amount of li...

PURPOSE The aim of this study was to determine the correlation between the pharyngeal airway space and head posture after mandibular setback surgery for mandibular prognathism. MATERIALS AND METHODS Serial lateral cephalograms of 37 patients with mandibular prognathism who underwent intraoral vertical ramus osteotomy (IVRO) were evaluated before (T1) and immediately (T2), between 6 weeks and ...

For complex tasks such as parse selection, the creation of labelled training sets can be extremely costly. Resource-efficient schemes for creating informative labelled material must therefore be considered. We investigate the relationship between two broad strategies for reducing the amount of manual labelling necessary to train accurate parse selection models: ensemble models and active learni...

Ground-based Folurier Transform infrared (FTIR) instruments are being produced at the University of Wisconsin (UW) and the Unliversity of Denver (UD) for the Atmospheric Radiation Measurement (ARM) Program's Cloud and Radiation Te:stbed (CART) sites as part of a joint Instrument Development Program (lOP). The three instrument types under development are summarized in Table 1 . For each ARM site...

Patients with schizophrenia tend to have impaired source monitoring and intact item recognition, suggesting an over-reliance of familiarity effects. We previously demonstrated that providing patients with a levels-of-processing (LOP) semantic encoding strategy normalized source monitoring. The current blood-oxygen-level-dependent (BOLD) functional magnetic resonance imaging (fMRI) study tests t...
