-
(Academic Press Inc., 2015)In the heart, insulin controls key functions such as metabolism, muscle contraction and cell death. However, all studies have been focused on insulin action during reperfusion. Here we explore the cardioprotective action ...
-
(Oxford University Press, 1975)AUTHORS' SYNOPSIS: The mechanical effects of heart contraction on coronary flow were studied in the dog heart by implanting vessels in the subendocardial and subepicardial layers of the left ventricular wall and perfusing ...
-
(Oxford University Press, 1993)Objective: The aim was to clarify the role of cyclic AMP dependent protein kinase (PKA) and changes in mechanical heart function during development of cardiac hypertrophy induced by volume overload. Methods: Protein and ...
-
(NLM (Medline), 2018)Background: Numerous studies have proposed the use of fluorescent semiconductor nanoparticles or quantum dots (QDs) as novel tools to label cells and tumors. However, QD applications are limited by their toxicity in ...
-
(Springer Verlag, 2018)High-energy methods for the manufacturing of nanomedicines are widely used; however, interest in low-energy methods is increasing due to their simplicity, better control over the process, and energy-saving characteristics ...
-
(Oxford University Press, 1976)AUTHORS' SYNOPSIS: The effect of tachycardia on the distribution of coronary blood flow was studied in the dog heart using the radioactive microsphere technique. Increasing heart rate from 1.7 to 3.0 Hz produced an increment ...
