Structural violence as a driver of COVID-19 vaccine hesitancy and low vaccine uptake among people experiencing homelessness in Toronto, Canada: A qualitative study.

Background: People experiencing homelessness are at increased risk of contracting SARS-CoV-2 and of severe complications of COVID-19. Vaccination is promoted as a key strategy to protect against severe illness from SARS-CoV-2 infection, but rates of vaccination among people experiencing homelessness are lower than the general population. Studies suggest lower uptake is a result of vaccine hesitancy, but few theoretically engage with the structural drivers of vaccine hesitancy.

Young people's lived sexual and reproductive health citizenship: participation and power of youth in Malawi.

This qualitative, focused critical ethnographic study explores how young people's 'lived SRH citizenship' and their active roles realising their sexual and reproductive health (SRH) and rights, shape their agency and participation in decision-making in Malawi. Informed by postcolonial feminist and difference-centred citizenship theories, our findings reveal that age-based power differentials, systems of gerontocracy and a culture of adultism impede bona fide youth involvement in SRH policymaking, making young citizens' participation more of an illusion than reality. Although democratisation and decentralisation aim to promote youth engagement, SRH policy spaces/processes lack institutionalised processes for integrating youth and remain dominated by donors and government.

Bridging the gap: a qualitative process evaluation from the perspectives of healthcare professionals of an audit-and-feedback-based intervention to improve transition to adult care for young people living with type 1 diabetes.

Background: The transition from pediatric to adult care is a vulnerable time for young people living with type 1 diabetes (T1D). Bridging the Gap (BTG) is an audit-and-feedback (AF) intervention aimed at improving both transitions-in-care processes and diabetes management in the year following transition. As part of BTG, we conducted a qualitative process evaluation to understand: (a) what was implemented and how; and (b) the contextual factors (micro-, meso- and macro-) that affected implementation, outcomes and study processes.

Physicians' perspectives on COVID-19 vaccinations for children: a qualitative exploration in Ontario, Canada.

Objectives: Parents' decisions to vaccinate their children against COVID-19 are complex and often informed by discussions with primary care physicians. However, little is known about physicians' perspectives on COVID-19 vaccinations for children or their experiences counselling parents in their decision-making. We explored physicians' experiences providing COVID-19 vaccination recommendations to parents and their reflections on the contextual factors that shaped these experiences.

Sexual and Reproductive Health Outcomes Among Adolescent Females During the COVID-19 Pandemic.

Background And Objectives: Coronavirus disease 2019 (COVID-19) posed a significant threat to adolescents' sexual and reproductive health. In this study, we examined population-level pregnancy and sexual health-related care utilization among adolescent females in Ontario, Canada during the pandemic and evaluated relationships between these outcomes and key sociodemographic characteristics.

Methods: This was a population-based, repeated cross-sectional study of >630 000 female adolescents (12-19 years) during the prepandemic (January 1, 2018-February 29, 2020) and COVID-19 pandemic (March 1, 2020-December 31, 2022) periods.

Participation of young women in sexual and reproductive health decision-making in Malawi: Local realities versus global rhetoric.

Despite the global prioritization of addressing adolescent girls' and young women's sexual and reproductive health (SRH) and participatory rights, little research has examined their lived experiences in shaping their engagement in SRH decision-making processes in the global South. Further, few studies have explored how structural and societal factors influence their agency and participation. This critical and focused ethnography, informed by postcolonial feminist and difference-centred citizenship theories, conducted in Malawi (2017-2018) elicited perspectives of youth and key informants to help address these knowledge gaps.

Parents' perspectives on SARS-CoV-2 vaccinations for children: a qualitative analysis.

Background: Uptake of the SARS-CoV-2 vaccine for children aged 5-11 years has been lower than anticipated in Canada. Although research has explored parental intentions toward SARS-CoV-2 vaccination for children, parental decisions regarding vaccinations have not been studied in-depth. We sought to explore reasons why parents chose to vaccinate or not vaccinate their children against SARS-CoV-2 to better understand their decisions.

Thrombin-Mediated Formation of Globular Adiponectin Promotes an Increase in Adipose Tissue Mass.

A decrease in the circulating levels of adiponectin in obesity increases the risk of metabolic complications, but the role of globular adiponectin, a truncated form produced by proteolytic cleavage, has not been defined. The objective of this investigation was to determine how globular adiponectin is generated and to determine whether this process impacts obesity. The cleavage of recombinant full-length adiponectin into globular adiponectin by plasma in vitro was used to identify Gly-93 as the N-terminal residue after proteolytic processing.

Scleraxis and fibrosis in the pressure-overloaded heart.

Aims: In response to pro-fibrotic signals, scleraxis regulates cardiac fibroblast activation in vitro via transcriptional control of key fibrosis genes such as collagen and fibronectin; however, its role in vivo is unknown. The present study assessed the impact of scleraxis loss on fibroblast activation, cardiac fibrosis, and dysfunction in pressure overload-induced heart failure.

Methods And Results: Scleraxis expression was upregulated in the hearts of non-ischemic dilated cardiomyopathy patients, and in mice subjected to pressure overload by transverse aortic constriction (TAC).

Growth State-Dependent Expression of Arachidonate Lipoxygenases in the Human Endothelial Cell Line EA.hy926.

Endothelial cells regulate vascular homeostasis through the secretion of various paracrine molecules, including bioactive lipids, but little is known regarding the enzymes responsible for generating these lipids under either physiological or pathophysiological conditions. Arachidonate lipoxygenase (ALOX) expression was therefore investigated in confluent and nonconfluent EA.h926 endothelial cells, which represent the normal quiescent and proliferative states, respectively.

Genetic Regulation of Vertebrate Forebrain Development by Homeobox Genes.

Forebrain development in vertebrates is regulated by transcription factors encoded by homeobox, bHLH and forkhead gene families throughout the progressive and overlapping stages of neural induction and patterning, regional specification and generation of neurons and glia from central nervous system (CNS) progenitor cells. Moreover, cell fate decisions, differentiation and migration of these committed CNS progenitors are controlled by the gene regulatory networks that are regulated by various homeodomain-containing transcription factors, including but not limited to those of the (paired), , (orthodenticle), (genetic screened), and (distal-less) homeobox gene families. This comprehensive review outlines the integral role of key homeobox transcription factors and their target genes on forebrain development, focused primarily on the telencephalon.

Economic costs of childhood stunting to the private sector in low- and middle-income countries.

Background: Stunting during childhood has long-term consequences on human capital, including decreased physical growth, and lower educational attainment, cognition, workforce productivity and wages. Previous research has quantified the costs of stunting to national economies however beyond a few single-country datasets there has been a limited number of which have used diverse datasets and have had a dedicated focus on the private sector, which employs nearly 90% of the workforce in many low- and middle-income countries (LMICs). We aimed to examine (i) the impact of childhood stunting on income loss of private sector workforce in LMICs; (ii) to quantify losses in sales to private firms in LMICs due to childhood stunting; and (iii) to estimate potential gains (benefit-cost ratios) if stunting levels are reduced in select high prevalence countries.

A Comprehensive Analysis of the Efficacy of Resveratrol in Atherosclerotic Cardiovascular Disease, Myocardial Infarction and Heart Failure.

Atherosclerosis, myocardial infarction (MI) and heart failure (HF) are the main causes of mortality and morbidity around the globe. New therapies are needed to better manage ischemic heart disease and HF as existing strategies are not curative. Resveratrol is a stilbene polyphenolic compound with favorable biological effects that counter chronic diseases.

Comparative and Combinatorial Effects of Resveratrol and Sacubitril/Valsartan alongside Valsartan on Cardiac Remodeling and Dysfunction in MI-Induced Rats.

The development and progression of heart failure (HF) due to myocardial infarction (MI) is a major concern even with current optimal therapy. Resveratrol is a plant polyphenol with cardioprotective properties. Sacubitril/valsartan is known to be beneficial in chronic HF patients.

Non-communicable diseases among adolescents: current status, determinants, interventions and policies.

Background: Addressing non-communicable disease (NCDs) is a global priority in the Sustainable Development Goals, especially for adolescents. However, existing literature on NCD burden, risk factors and determinants, and effective interventions and policies for targeting these diseases in adolescents, is limited. This study develops an evidence-based conceptual framework, and highlights pathways between risk factors and interventions to NCD development during adolescence (ages 10-19 years) and continuing into adulthood.

Drivers of stunting reduction in Nepal: a country case study.

Background: Chronic child malnutrition represents a serious global health concern. Over the last several decades, Nepal has seen a significant decline in linear growth stunting - a physical manifestation of chronic malnutrition - despite only modest economic growth and significant political instability.

Objective: This study aimed to conduct an in-depth assessment of the determinants of stunting reduction in Nepal from 1996 to 2016, with specific attention paid to national-, community-, household-, and individual-level factors, as well as relevant nutrition-specific and -sensitive initiatives rolled out within the country.

Drivers of stunting reduction in Peru: a country case study.

Background: Peru reduced its under-5 child stunting prevalence notably from 31.3% in 2000 to 13.1% in 2016.

Drivers of stunting reduction in Ethiopia: a country case study.

Background: Chronic undernutrition in children continues to be a global public health concern. Ethiopia has documented a significant decline in the prevalence of childhood stunting, a measure of chronic undernutrition, over the last 20 y.

Objectives: The aim of this research was to conduct a systematic assessment of the determinants that have driven child stunting reduction in Ethiopia from 2000 to 2016, focused on the national, community, household, and individual level.

Wavelength- and irradiance-dependent changes in intracellular nitric oxide level.

Significance: Photobiomodulation (PBM) refers to the beneficial effects of low-energy light absorption. Although there is a large body of literature describing downstream physiological benefits of PBM, there is a limited understanding of the molecular mechanisms underlying these effects. At present, the most popular hypothesis is that light absorption induces release of nitric oxide (NO) from the active site of cytochrome c oxidase (COX), allowing it to bind O2 instead.

Drivers of stunting reduction in Senegal: a country case study.

Background: Senegal has been an exemplar country in the West African region, reducing child stunting prevalence by 17.9% from 1992 to 2017.

Objectives: In this study, we aimed to conduct a systematic in-depth assessment of factors at the national, community, household, and individual levels to determine the key enablers of Senegal's success in reducing stunting in children <5 y old between 1992/93 and 2017.

Drivers of stunting reduction in the Kyrgyz Republic: A country case study.

Background: Chronic malnutrition among infants and children continues to represent a global public health concern. The Kyrgyz Republic has achieved rapid declines in stunting over the last 20 y, despite modest increases in gross domestic product per capita.

Objective: This study aimed to conduct a systematic, in-depth assessment of national, community, household, and individual drivers of nutrition change and stunting reduction, as well as nutrition-specific and -sensitive policies and programs, in the Kyrgyz Republic.

Youth participation in sexual and reproductive health: policy, practice, and progress in Malawi.

Objectives: Ensuring youth participation in policymaking that affects their health and well-being is increasingly recognized as a strategy to improve young people's reproductive health. This paper aimed to describe the policy context and analyze underlying factors that influence youth participation in sexual and reproductive health (SRH) policymaking in Malawi.

Methods: This critical, focused ethnographic study is informed by postcolonial feminism and difference-centered citizenship theory, based on data collected from October 2017 to May 2018.

Resveratrol prevents palmitic-acid-induced cardiomyocyte contractile impairment.

Long-chain saturated fatty acids, especially palmitic acid (PA), contribute to cardiomyocyte lipotoxicity. This study tests the effects of PA on adult rat cardiomyocyte contractile function and proteins associated with calcium regulating cardiomyocyte contraction and relaxation. Adult rat cardiomyocytes were pretreated with resveratrol (Resv) and then treated with PA.

Divergent Effects of Resveratrol on Rat Cardiac Fibroblasts and Cardiomyocytes.

In this study, we tested the potential cardioprotective effects of the phytoalexin resveratrol (Rsv) on primary adult rat cardiac fibroblasts (CF), myofibroblasts (MF) and cardiomyocytes. Adult rat CF and cardiomyocytes were isolated from male 10-week old Sprague-Dawley rats, cultured for either 24 h (cardiomyocytes) or 48 h (CF) before treatments. To isolate MF, CF were trypsinized after 48 h in culture, seeded in fresh plates and cultured for 24 h prior to treatment.
