Molecular and metabolomic characterization of hiPSC-derived cardiac fibroblasts transitioning to myofibroblasts.

Background: Mechanical stress and pathological signaling trigger the activation of fibroblasts to myofibroblasts, which impacts extracellular matrix composition, disrupts normal wound healing, and can generate deleterious fibrosis. Myocardial fibrosis independently promotes cardiac arrhythmias, sudden cardiac arrest, and contributes to the severity of heart failure. Fibrosis can also alter cell-to-cell communication and increase myocardial stiffness which eventually may lead to lusitropic and inotropic cardiac dysfunction.

Transplantation of decellularized porcine kidney grafts repopulated with primary human cells demonstrates filtration function in pigs.

Background: End-stage renal disease is a growing global health issue, disproportionately impacting low- and middle-income countries. While kidney transplantation remains the best treatment for end-stage renal disease, access to this treatment modality is limited by chronic donor organ shortages. To address this critical need, we are developing transplantable bioengineered kidney grafts.

Impart backspin and pitch the ball up: strategies cricket fast bowlers can employ to generate late swing.

In cricket fast bowling, late swing can increase interception difficulty for opposition batters. However, little is known about the occurrence and cause of late swing. This study investigated ball kinematics and the effect of changing kinematics on late swing with new cricket balls.

The PI3K-AKT-mTOR axis persists as a therapeutic dependency in KRAS-driven non-small cell lung cancer.

Introduction: KRAS and KRAS inhibitors represent a major translational breakthrough for non-small cell lung cancer (NSCLC) and cancer in general by directly targeting its most mutated oncoprotein. However, resistance to these small molecules has highlighted the need for rational combination partners necessitating a critical understanding of signaling downstream of KRAS mutant isoforms.

Methods: We contrasted tumor development between Kras and Kras genetically engineered mouse models (GEMMs).

Differences in COVID-19 Vaccination and Experiences among Patients with Hypertension in Colombia and Jamaica during the COVID-19 Pandemic.

During the COVID-19 pandemic, hypertensive patients had increased infection and healthcare disruption in many low- and middle-income countries (LMICs) with limited vaccine access. The objective of this report is to describe COVID-19 experiences and vaccination uptake among hypertensive patients in Colombia and Jamaica. A cross-sectional study of patients with hypertension was conducted in primary care clinics in both countries between 2021 and 2022.
