Research Highlights: Macrophages Pick-up “Trash” from Heart Muscles

Image Source: https://www.vet.cornell.edu/ Original Article: https://doi.org/10.1016/j.cell.2020.08.031 Cardiomyocytes are the cells responsible for generating contractile force in the intact heart. Cardiomyocytes are subjected to the intense mechanical stress and metabolic demands of the beating heart. Cardiomyocytes are long-lived and rarely renewed. It is unclear whether these cardiomyocytes manage to preserve homeostasis on their own. Researchers discovered … Continue reading Research Highlights: Macrophages Pick-up “Trash” from Heart Muscles

Trans Fats

By Kagor at the Ukrainian language Wikipedia, CC BY-SA 3.0, https://commons.wikimedia.org/w/index.php?curid=33636382 Trans Fats (OpenStax Biology 2e) The food industry artificially hydrogenates oils to make them semi-solid and of a consistency desirable for many processed food products. Simply speaking, hydrogen gas is bubbled through oils to solidify them. During this hydrogenation process, double bonds of the cis- … Continue reading Trans Fats

The Evolutionary Significance of Cytochrome c

By Vossman – Own work, CC BY-SA 3.0, https://commons.wikimedia.org/w/index.php?curid=16469416 The Evolutionary Significance of Cytochrome c (OpenStax Biology 2e) Cytochrome c is an important component of the electron transport chain, a part of cellular respiration, and it is normally located in the cellular organelle, the mitochondrion. This protein has a heme prosthetic group, and the heme’s … Continue reading The Evolutionary Significance of Cytochrome c

Vertebrate Axis Formation

Animal bodies have three axes for symmetry. (credit: modification of work by NOAA) OpenStax Biology 2e Even as the germ layers form, the ball of cells still retains its spherical shape. However, animal bodies have lateral-medial (left-right), dorsal-ventral (back-belly), and anterior-posterior (head-feet) axes. How are these established? In one of the most seminal experiments ever … Continue reading Vertebrate Axis Formation

Research Highlights: Excessive Exercise Linked to Mitochondrial Functional Impairment and Reduction of Glucose Tolerance

Image Source: https://doi.org/10.1016/j.cmet.2021.02.017 Excessive Exercise Linked to Mitochondrial Functional Impairment and Reduction of Glucose Tolerance Exercise can have a positive effect on metabolic health.Exercise can increase mitochondrial oxidative capacity and improve regulation of glucose.Exercise is initially encouraged to treat a number of metabolic diseases.However, the association between therapeutic benefits and excessive exercise has not been … Continue reading Research Highlights: Excessive Exercise Linked to Mitochondrial Functional Impairment and Reduction of Glucose Tolerance
