Topically Delivered Treg‐Attracting Microparticle‐Hydrogel Composites Recruit Regulatory T Cells and Limit Cardiac Injury After Severe Ischemia

Advanced Healthcare Materials, EarlyView.
CCL22‐releasing PLGA microparticles (MP) suspended in topically applied hydrogels (HEART) establish a sustained chemokine gradient at the injured myocardium. HEART recruits CCR4+ regulatory T cells, reduces infarct size and graft fibrosis, and improves cardiac function.

Reduced Graphene Oxide Enhances the Vascular Organization and Contractile Performance of Fibrin‐Gelatin‐Based Engineered Cardiac Tissue

Advanced Materials Interfaces, EarlyView.
Fibrin–gelatin hydrogels functionalized with reduced graphene oxide create a mechanically stable and bioactive 3D environment for engineered cardiac tissue. The composite matrix promotes endothelial lumen formation, enhances sarcomeric protein expression, and increases contractile performance of embedded cardiomyocytes.

Allometric scaling for left ventricular mass and geometry in male and female athletes of mixed and endurance sports

Echo Research and Practice
Background The athlete’s heart (AH) defines the phenotypical changes that occur in response to chronic exercise training. Echocardiographic assessment of the AH is used to calculate LV mass (LVM) and determine chamber geometry.

Unusual Left Ventricular Mass detected after Myocardial Infarction-A Case Report [PDF]

, 2011
Any major cardiac mass, by virtue of their anatomic location, is capable of producing a myriad of cardiac, embolic and systemic symptoms, sometimes with fatal consequences. We report a case of 37 year old patient with anterior wall MI with EF of 40%, and

Extrusion‐Based Bioprinting of Living Bioinks for Tissue and Organ Engineering

Advanced Materials Technologies, EarlyView.
Extrusion‐based bioprinting is presented as the most versatile route for fabricating living, heterogeneous tissues. Its ability to combine diverse bioinks, support matrices, and advanced printhead geometries transforms familiar constraints into powerful biofabrication opportunities.

Normotensive offspring of hypertensive Nigerians have increased Left ventricular mass and abnormal geometric patterns

The Pan African Medical Journal, 2012
BACKGROUND:Reports have shown that normotensive offspring of hypertensive parents (OHP) are at increased risk of developing systemic hypertension (SH) and adverse cardiovascular events later in life. The pathological antecedents of this are thought to be

From Rigid to Soft Robotic Approaches for Neuroendoscopy

Advanced Robotics Research, EarlyView.
Robotic assistance has had minimal impact on deep intraventricular surgeries, where small‐scale, precision, and reduced invasiveness can contribute to improved patient outcomes. Emerging technologies in rigid, soft, and hybrid robotics are reviewed to identify the most promising mechanisms for deep brain navigation in addition to an attempt to identify

Gonadotropin‐Inhibitory Hormone (GnIH) and Its Receptor GPR147 Mediates Acute Stress‐Induced Activation of the Locus Coeruleus‐SAM Axis

Advanced Science, EarlyView.
ABSTRACT Gonadotropin‐inhibitory hormone (GnIH, also known as RFamide‐related peptide‐3, RFRP‐3) is a hypothalamic neuropeptide that regulates vertebrate reproduction via its receptor GPR147. Although GnIH is known to mediate stress‐induced reproductive suppression, its role in broader stress responses remains unclear.

Prognostic Value of Cardiac Troponin I and Left Ventricular Hypertrophy in Mortality of Chronic Hemodialysis Patients [PDF]

Cardiovascular events are the most common cause of death in hemodialysis patients. Cardiac biomarkers and especially Cardiac troponin I has been used as a prognostic marker in hemodialysis patients and there is some controversies about its value.

Cardiovascular Risk Factors from Early Life Predict Future Adult Cardiac Structural and Functional Abnormalities: A Systematic Review of the Published Literature [PDF]

, 2014
Background: Clinical practice evaluates cardiovascular risk based on current risk factor (RF) levels [Blood pressure (BP), body mass index (BMI) and glycaemic control] largely disregarding previous risk-factor history over the totality of the life course.
