Article 1: Mir147 Limits the Contribution of Non-Foamy Macrophages to Atherosclerosis.
Journal: Circulation
PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41944070
Summary: The study found that Mir147 (microRNA 147) limits the contribution of non-foamy macrophages to atherosclerosis by downregulating inflammatory activation. Specifically, Mir147-3p is upregulated by inflammation and functions to reduce inflammatory responses within these macrophages. This mechanism prevents the inflammatory activation of non-foamy macrophages, thereby reducing their role in the progression of atherosclerosis. The findings establish a new regulatory pathway in macrophage biology relevant to atherosclerotic disease.
Article 2: Multi-Organ Physiologic Deficits During Exercise Identify Clinical and Molecular Predisposition to Heart Failure with Preserved Ejection Fraction.
Journal: Circulation
PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41944041
Summary: This study found that multi-organ physiologic deficits identified during exercise characterize Heart Failure with Preserved Ejection Fraction (H. F. pEF). The research identified seven specific exercise-related deficits, including reduced peak oxygen uptake and chronotropic incompetence, in patients with this condition. These multi-organ limitations were directly associated with the severity and prognosis of Heart Failure with Preserved Ejection Fraction. The findings establish a link between these exercise deficits and both clinical and molecular predispositions to Heart Failure with Preserved Ejection Fraction.
Article 3: Olfactory Receptor Activation Reduces Platelet Reactivity and Arterial Thrombosis Through Actin Cytoskeleton Remodeling.
Journal: Circulation
PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41944007
Summary: The study found that activating the human olfactory receptor 2 L 13 (O. R. 2 L 13) on platelets significantly reduced platelet aggregation in laboratory settings. Activation of O. R. 2 L 13 also provided robust protection against arterial thrombosis in living organisms. This antithrombotic effect occurs through the mechanism of actin cytoskeleton remodeling within the platelets. These findings identify platelet O. R. 2 L 13 activation as a novel and effective strategy for reducing platelet reactivity and preventing arterial thrombosis.
Article 4: Characteristics of Protein Profiling and Biomarkers in Aortic Regurgitation With Heart Failure.
Journal: Journal of the American Heart Association
PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41944198
Summary: This study identified 23 differentially expressed proteins in patients with severe aortic regurgitation compared to control subjects. Specifically, 7 proteins were upregulated and 16 were downregulated in severe aortic regurgitation cases. Key differentially expressed proteins included galectin three and matrix metalloproteinase nine. The data demonstrated that these differentially expressed proteins offer potential as biomarkers for the diagnosis and therapeutic monitoring of severe aortic regurgitation.
Article 5: Elevated Interleukin-6 Levels in Socioeconomically Disadvantaged Children With Borderline Subclinical Rheumatic Heart Disease in São Paulo, Brazil: A Prospective Cohort Study Highlighting Early Detection and Treatment Opportunities.
Journal: Journal of the American Heart Association
PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41944184
Summary: The study found that interleukin six levels were significantly elevated in children with borderline subclinical rheumatic heart disease (S. C. R. H. D.) compared to healthy controls at baseline, with a P value of 0.006. These elevated interleukin six levels persisted longitudinally throughout the two-year follow-up period in both borderline and definite subclinical rheumatic heart disease patients, with a P value of 0.004. The data demonstrate that interleukin six serves as a key inflammatory biomarker for early detection and disease activity in subclinical rheumatic heart disease. This persistent inflammation suggests opportunities for early therapeutic interventions in socioeconomically disadvantaged children.

Article number one. Mir147 Limits the Contribution of Non-Foamy Macrophages to Atherosclerosis.

Specifically, Mir147-3p is upregulated by inflammation and functions to reduce inflammatory responses within these macrophages. This mechanism prevents the inflammatory activation of non-foamy macrophages, thereby reducing their role in the progression of atherosclerosis. The findings establish a new regulatory pathway in macrophage biology relevant to atherosclerotic disease.
Article number two. Multi-Organ Physiologic Deficits During Exercise Identify Clinical and Molecular Predisposition to Heart Failure with Preserved Ejection Fraction. This study found that multi-organ physiologic deficits identified during exercise characterize Heart Failure with Preserved Ejection Fraction (H. F. pEF). The research identified seven specific exercise-related deficits, including reduced peak oxygen uptake and chronotropic incompetence, in patients with this condition. These multi-organ limitations were directly associated with the severity and prognosis of Heart Failure with Preserved Ejection Fraction. The findings establish a link between these exercise deficits and both clinical and molecular predispositions to Heart Failure with Preserved Ejection Fraction.

The study found that activating the human olfactory receptor 2 L 13 (O. R. 2 L 13) on platelets significantly reduced platelet aggregation in laboratory settings. Activation of O.
