Nutrition and Lifestyle Coaching: An Interprofessional Course for Pharmacy, Medical, and Dietetic Students.

Background Poor nutrition and lifestyle choices are major contributors to the development and progression of various chronic diseases. Enhancing patients' awareness of healthy nutrition and lifestyle habits by interprofessional healthcare teams can play a significant role in tackling many chronic diseases, particularly in underserved communities with inequitable access to healthcare and educational opportunities. However, healthcare professionals are not adequately prepared to provide effective, culturally competent nutrition and lifestyle coaching due to a lack of emphasis on these topics in the curricula of many healthcare professional programs.

P2Y purinergic signaling in prostate cancer: Emerging insights into pathophysiology and therapy.

Despite recent advances in the treatment landscape for prostate cancer, many challenges still remain. A more profound understanding of prostate cancer pathogenesis and the underlying mechanisms is critical to developing novel therapeutics strategies. Extracellular nucleotides play a central role in the growth and progression of a variety of cancer types - almost all tumor cells and immune cells express purinergic membrane receptors for extracellular nucleotides (ATP, ADP, UTP, UDP, UDP-sugar) and their metabolic nucleoside products (e.

Blending team-based learning and game-based learning in pharmacy education.

Background And Purpose: Team-based learning (TBL) and game-based learning (GBL) are evidence-based active learning pedagogies. This study reports a learning experience that harnesses TBL and GBL benefits by blending both pedagogies (referred herein as TGL) in the facilitation of an immunology module for pharmacy students. The manuscript presents the rationale for using TGL, a description of the TGL process, student outcomes and satisfaction with the learning experience, and TGL applicability in different topics/disciplines.

SARS-CoV-2 early infection signature identified potential key infection mechanisms and drug targets.

Background: The ongoing COVID-19 outbreak has caused devastating mortality and posed a significant threat to public health worldwide. Despite the severity of this illness and 2.3 million worldwide deaths, the disease mechanism is mostly unknown.

Enhancing nutrition and lifestyle education for healthcare professional students through an interprofessional, team-based training program.

Background And Purpose: Nutrition and lifestyle modifications are effective interventions in tackling many chronic diseases, including cardiovascular diseases. However, healthcare professionals are not sufficiently trained in nutrition and lifestyle education. To address this gap, we established an interprofessional, team-based framework to train healthcare professional students on healthy nutrition and culturally competent dietary coaching and motivational interviewing.

Pim1 maintains telomere length in mouse cardiomyocytes by inhibiting TGFβ signalling.

Aims: Telomere attrition in cardiomyocytes is associated with decreased contractility, cellular senescence, and up-regulation of proapoptotic transcription factors. Pim1 is a cardioprotective kinase that antagonizes the aging phenotype of cardiomyocytes and delays cellular senescence by maintaining telomere length, but the mechanism remains unknown. Another pathway responsible for regulating telomere length is the transforming growth factor beta (TGFβ) signalling pathway where inhibiting TGFβ signalling maintains telomere length.

Hypoxia Prevents Mitochondrial Dysfunction and Senescence in Human c-Kit Cardiac Progenitor Cells.

Senescence-associated dysfunction deleteriously affects biological activities of human c-Kit cardiac progenitor cells (hCPCs), particularly under conditions of in vitro culture. In comparison, preservation of self-renewal and decreases in mitochondrial reactive oxygen species (ROS) are characteristics of murine CPCs in vivo that reside within hypoxic niches. Recapitulating hypoxic niche oxygen tension conditions of ∼1% O in vitro for expansion of hCPCs rather than typical normoxic cell culture conditions (21% O ) could provide significant improvement of functional and biological activities of hCPCs.

Mechanisms of Cardiac Repair and Regeneration.

Cardiovascular regenerative therapies are pursued on both basic and translational levels. Although efficacy and value of cell therapy for myocardial regeneration can be debated, there is a consensus that profound deficits in mechanistic understanding limit advances, optimization, and implementation. In collaboration with the TACTICS (Transnational Alliance for Regenerative Therapies in Cardiovascular Syndromes), this review overviews several pivotal aspects of biological processes impinging on cardiac maintenance, repair, and regeneration.

Cardiac c-Kit Biology Revealed by Inducible Transgenesis.

Rationale: Biological significance of c-Kit as a cardiac stem cell marker and role(s) of c-Kit+ cells in myocardial development or response to pathological injury remain unresolved because of varied and discrepant findings. Alternative experimental models are required to contextualize and reconcile discordant published observations of cardiac c-Kit myocardial biology and provide meaningful insights regarding clinical relevance of c-Kit signaling for translational cell therapy.

Objective: The main objectives of this study are as follows: demonstrating c-Kit myocardial biology through combined studies of both human and murine cardiac cells; advancing understanding of c-Kit myocardial biology through creation and characterization of a novel, inducible transgenic c-Kit reporter mouse model that overcomes limitations inherent to knock-in reporter models; and providing perspective to reconcile disparate viewpoints on c-Kit biology in the myocardium.

Empowering human cardiac progenitor cells by P2Y nucleotide receptor overexpression.

Key Points: Autologous cardiac progenitor cell (CPC) therapy is a promising approach for treatment of heart failure (HF). There is an unmet need to identify inherent deficits in aged/diseased human CPCs (hCPCs) derived from HF patients in the attempts to augment their regenerative capacity prior to use in the clinical setting. Here we report significant functional correlations between phenotypic properties of hCPCs isolated from cardiac biopsies of HF patients, clinical parameters of patients and expression of the P2Y purinergic receptor (P2Y R), a crucial detector for extracellular UDP-sugars released during injury/stress.

P2Y Nucleotide Receptor Prompts Human Cardiac Progenitor Cell Activation by Modulating Hippo Signaling.

Rationale: Autologous stem cell therapy using human c-Kit cardiac progenitor cells (hCPCs) is a promising therapeutic approach for treatment of heart failure (HF). However, hCPCs derived from aged patients with HF with genetic predispositions and comorbidities of chronic diseases exhibit poor proliferative and migratory capabilities, which impair overall reparative potential for injured myocardium. Therefore, empowering functionally compromised hCPCs with proregenerative molecules ex vivo is crucial for improving the therapeutic outcome in patients with HF.

Inflammation and Epithelial-Mesenchymal Transition in Pancreatic Ductal Adenocarcinoma: Fighting Against Multiple Opponents.

Pancreatic ductal adenocarcinoma (PDAC) is the most common type of pancreatic cancer and one of the most lethal human cancers. Inflammation is a critical component in PDAC initiation and progression. Inflammation also contributes to the aggressiveness of PDAC indirectly via induction of epithelial-mesenchymal transition (EMT), altogether leading to enhanced resistance to chemotherapy and poor survival rates.

Concurrent Isolation of 3 Distinct Cardiac Stem Cell Populations From a Single Human Heart Biopsy.

Rationale: The relative actions and synergism between distinct myocardial-derived stem cell populations remain obscure. Ongoing debates on optimal cell population(s) for treatment of heart failure prompted implementation of a protocol for isolation of multiple stem cell populations from a single myocardial tissue sample to develop new insights for achieving myocardial regeneration.

Objective: Establish a robust cardiac stem cell isolation and culture protocol to consistently generate 3 distinct stem cell populations from a single human heart biopsy.
