Leucine‐Dependent SLC7A5–PGAM5 Interaction Promotes Advanced Atherosclerosis Through Hindering Mitochondrial Function of Macrophages

Advanced Science, EarlyView.
Higher plasma leucine is associated with increased risk of new‐onset myocardial infarction. Leucine deprivation alleviates advanced atherosclerosis in mice. Tumor‐induced leucine deprivation reprograms macrophage metabolism and increases CD5Lhi macrophages in mouse plaques. Mechanistically, leucine deficiency reduced SLC7A5‐PGAM5 binding in macrophages,

Surgery of the aortic root: should we go for the valve-sparing root reconstruction or the composite graft-valve replacement is still the first choice of treatment for these patients?

Brazilian Journal of Cardiovascular Surgery, 2015
Objective:To compare the results of the root reconstruction with the aortic valve-sparing operation versus composite graftvalve replacement.Methods:From January 2002 to October 2013, 324 patients underwent aortic root reconstruction.

The use of transgenic animals for xenotransplantation: An update

Animal Models and Experimental Medicine, EarlyView.
One way to produce genetically modified pigs is to use somatic cell nuclear transfer (SCNT). This procedure involves removing the metaphase plate from a mature oocyte using micromanipulation and then transferring the modified nucleus from the donor somatic cell to the oocyte.

Noradrenergic and cholinergic innervation of the normal human heart and changes associated with cardiomyopathy

The Anatomical Record, EarlyView.
Abstract Autonomic nerves are crucial in cardiac function and pathology. However, data on the distribution of cholinergic and noradrenergic nerves in normal and pathologic human hearts is lacking. Nonfailing donor hearts were pressure‐perfusion fixed, imaged, and dissected. Left ventricular cardiomyopathy samples were also obtained.
