Unlabelled: Policy Points Efforts to address a perceived decline of comprehensiveness in primary care are hampered by the absence of a clear and common understanding of what comprehensiveness means. This scoping review mapped two domains of comprehensiveness (breadth of care and approach to care) as well as a set of factors that enable comprehensive practice. The resulting conceptual map supports greater clarity for future use of the term comprehensiveness, facilitating more precisely targeted research, practice, and policy efforts to improve primary care systems.

Accurately simulating the boundary layer is critical in improving climate model performance, which deeply relies on our understanding of the turbulence in the boundary layer. Turbulent energy sources in the boundary layer are traditionally believed to be dominated by waves, winds and convection.

Canadian provinces and territories have undertaken varied reforms to how primary care is funded, organized, and delivered, but equity impacts of reforms are unclear. We explore disparities in access to primary care by income, educational attainment, dwelling ownership, immigration, racialization, place of residence (metropolitan/non-metropolitan), and sex/gender, and how these have changed over time, using data from the Canadian Community Health Survey (2007/08 and 2015/16 or 2017/18). We observe disparities by income, educational attainment, dwelling ownership, recent immigration, immigration (regular place of care), racialization (regular place of care), and sex/gender.

The pandemic has also exacerbated many risk factors for poor mental health in the workplace, especially in public-facing jobs. Therefore, we sought to test the potential relationship between work setting and self-rated mental health.

Existing studies on burnout have mostly emphasized workplace culture, leadership, and employee engagement as key contributors to burnout. In this cross-sectional study, we examine the associations between Malach-Pines Short Burnout Measure (MPSBM) scores and participant's self reported personal characteristics, financial strain, workplace conditions, work-life balance, and social inclusion among Canadians living during the third wave of the COVID-19 pandemic.

Primary care system reforms in Canada may have had equity implications, but these have not been evaluated. We sought to determine if changes in primary care service use between 1999/2000 and 2017/2018 differ by neighbourhood income in British Columbia.

Objective: We conducted an environmental scan to explore the nature of private payment for primary care across Canada.
Method: We extracted data from clinic websites on funding models, range of services provided and whether they were independent or part of a chain.
Etoposide is a widely used anticancer drug that targets topoisomerase II, an essential nuclear enzyme. However, despite the fact that it has been in use and studied for more than 30years the specific site on the enzyme to which it binds is unknown. In order to identify the etoposide binding site(s) on topoisomerase II, a diazirine-based photoaffinity etoposide analog probe has been synthesized and its photoreactivity and biological activities have been characterized.

Gp120IIIB is a strain of a HIV glycoprotein with specificity for the CXCR4 receptor that induces neuronal apoptosis in in vitro models of acquired immunodeficiency syndrome (AIDS)-induced neurodegeneration. Since the catabolism of the neuropeptide N-acetylaspartylglutamate (NAAG) by glutamate carboxypeptidase (GCP) II increases cellular glutamate, an event associated with excitotoxicity, we hypothesized that inhibition of GCP II may prevent gp120IIIB-induced cell death.

Here, we examine possible mechanisms of gp120 and nucleoside reverse transcriptase inhibitors (NRTIs) in the pathogenesis of AIDS peripheral neuropathy. Neonatal dorsal root ganglion (DRG) neurons were found to undergo apoptosis in response to chronic treatment with gp120IIIB, an effect enhanced by the co-application of hCD4, as well as upon exposure to the nucleoside reverse transcriptase inhibitor (NRTI), 2',3'-dideoxyinosine (ddI).

Glutamate excitotoxicity has been implicated as a mechanism of MN death in both ALS and FALS. In this study, we tested whether a neuroprotective strategy involving potent and selective inhibitors of glutamate carboxypeptidase II (GCPII), which converts the abundant neuropeptide N-acetylaspartylglutamate to glutamate, could protect MNs in an in vitro and animal model of FALS.

We examined the ability of gp120IIIB to signal through the rat CXCR4 (rCXCR4) receptor and its dependence on the presence of the human CD4 (hCD4) protein in a number of cell systems. SDF-1alpha potently inhibited N-type Ca channels in cultured HEK293 cells expressing both the Ca channel subunits and rCXCR4 receptors.

Children with attention deficit hyperactivity disorder (ADHD) face an increased risk of poor achievement in school. Thus, knowledge of the cognitive processing abilities of children with ADHD is critical to understanding and improving their academic performance. Although many studies have focused on the specific nature of the attention deficit experienced by children with ADHD, few have examined higher order cognitive processing such as comprehension of stories.

Here we demonstrate that CEP-1347 (KT7515), an inhibitor of mixed lineage kinase 3 (MLK3), an upstream activator of JNK, inhibits gp120IIIB-induced apoptosis of hippocampal neurons. Furthermore, expression of wild type MLK3 in hippocampal pyramidal neurons enhanced gp120IIIB-induced neurotoxicity, whereas expression of a dominant negative MLK3 protected neurons from the toxic effects of the glycoprotein.

Impaired activity of the branched-chain 2-oxoacid dehydrogenase complex (BCOA-DH) causes accumulation of branched-chain L-amino (BCAA) and 2-oxoacids (BCOA) which may exert neurotoxic effects. Treatment comprises dietary management with strictly reduced quantities of protein and BCAA as well as aggressive intervention during acute neonatal and subsequent metabolic complications.

At the start, during and at the end of a 3 months' treatment with oral sustained release theophylline and during 1 week thereafter, the influence on airway hyperreactivity and ECP (eosinophil cationic protein) serum levels was investigated. Airway responsiveness was expressed as the cumulative provocative dose of methacholine necessary to decrease FEV1 by 20% (PD20-FEV1).

Abstract A seven compartment model was applied for evaluation of oral L-[1-(13)C]leucine loading tests (38 μmol/kg body wt.) in healthy volunteers. The model comprises transport and absorption in stomach and gut into a central L-leucine-compartment which is connected to a protein compartment and to the compartment of the corresponding 2-oxo acid.

Seventy-nine of 236 positively screened samples could not be tested for confirmation. Seropositive reactivity was observed in nine of 123 blood donors, and 3 of 46 healthy school children but banding patterns on Western blot were often sparse.

This ethnonursing qualitative investigation was focused on the domain of culture care values, expression and meanings of selected American Gypsies. The purpose of the study was to explicate culture care American Gypsy lifeways in order to help nurses understand this largely unknown culture, and to offer guidelines for providing culturally congruent nursing care. Leininger's theory of Culture Care Diversity and Universality was the appropriate theory to use for this study, along with the ethnonursing research method to generate emic and etic grounded data.
