Prognostic significance of right bundle branch block in patients with acute inferior myocardial infarction [PDF]

, 2009
There is little information available concerning the influence of right bundle branch block (RBBB) on the prognosis of patients with inferior myocardial infarction (MI).

Modelling Atherosclerotic Plaque Cap Mechanics: Microcalcifications Reduce Mechanical Properties in Mesenchymal Stromal Cell‐Based Model

Advanced Biology, EarlyView.
This study develops a tissue‐engineered model of the atherosclerotic cap using human mesenchymal stromal cells (MSCs). After 2 weeks of culture to produce a collagenous matrix, a mineralizing medium induces microcalcifications over 4 weeks. These constructs, imaged with second harmonic generation microscopy, lead to reduced ultimate stress at rupture ...

Divergent roles of red cell arginase in humans and mice: RBC Arg1 KO mice show preserved systemic l-arginine bioavailability and infarct size in vivo

Redox Biology
In humans and other primates, red blood cells (RBCs) constitutively express high levels of liver-type arginase 1 (Arg1), which regulates systemic l-arginine and nitric oxide (NO) bioavailability, particularly under pathological conditions such as sickle ...

Systemic Atherosclerotic Inflammation Following Acute Myocardial Infarction: Myocardial Infarction Begets Myocardial Infarction [PDF]

Journal of the American Heart Association, 2015
Background Preclinical data suggest that an acute inflammatory response following myocardial infarction (MI) accelerates systemic atherosclerosis. Using combined positron emission and computed tomography, we investigated whether this phenomenon occurs in humans. Methods and Results

Engineering the Hierarchical Porosity of Granular Hydrogel Scaffolds Using Porous Microgels to Improve Cell Recruitment and Tissue Integration

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
By fabricating and covalently assembling gelatin methacryloyl (GelMA) porous microgels, a new class of granular hydrogel scaffolds with hierarchical porosity is developed. These scaffolds have a significantly higher void fraction than their counterparts made up of nonporous microgels, enhancing cell recruitment and tissue integration. This research may

Is combined myocardial performance index and tricuspid annular plane systolic excursion a better predictive estimator than each of them alone in patients with inferior ST-elevation myocardial infarction?

Türk Kardiyoloji Derneği Arşivi, 2014
Objectives: We aimed to assess the combined estimator of left ventricular (LV) myocardial performance index (MPI) and tricuspid annular plane systolic excursion (TAPSE) as a pooled independent predictive factor for hospital mortality and one-year ...

Hypertension and myocardial infarction

Journal of the American College of Cardiology, 1983
Because hypertension and myocardial infarction are closely linked in several ways, a better understanding of this relation leads to more effective prophylaxis and management. Management should be directed at three different areas: 1) the prevention of a first myocardial infarction, 2) the prevention of complications after an infarction, and 3) the ...

Myocardial infarction in the young

Journal of Postgraduate Medicine, 2009
An increasing number of patients under 40 years of age are being hospitalized with the diagnosis of acute myocardial infarction. This is partly due to the increased prevalance of risk factors for atherosclerosis in the younger age group; especially increased incidence of impaired fasting glucose, high triglyceride, low high ...

Harnessing Outer Space for Improved Electrocaloric Cooling

Advanced Functional Materials, EarlyView.
A novel radiative heat sink/source‐integrated electrocaloric (R‐iEC) system combines the electrocaloric (EC) effect with a thermally conductive radiative cooler (TCRC) to address heat dissipation limitations in EC devices. Utilizing outer space as a heat sink, the system achieves up to 240 W m−2 of heat dissipation performance, making it highly ...

Biomaterial Strategies for Targeted Intracellular Delivery to Phagocytes

Advanced Functional Materials, EarlyView.
Phagocytes are essential to a functional immune system, and their behavior defines disease outcomes. Engineered particles offer a strategic opportunity to target phagocytes, harnessing inflammatory modulation in disease. By tuning features like size, shape, and surface, these systems can modulate immune responses and improve targeted treatment for a ...
