Human eyes do not need monochromatic aberrations for dynamic accommodation

Ophthalmic and Physiological Optics, Volume 37, Issue 5, Page 602-609, September 2017., 2017
Abstract Purpose To determine if human accommodation uses the eye's own monochromatic aberrations to track dynamic accommodative stimuli. Methods Wavefront aberrations were measured while subjects monocularly viewed a monochromatic Maltese cross moving sinusoidally around 2D of accommodative demand with 1D amplitude at 0.2 Hz.

Apple Peel Supplemented Diet Reduces Parameters of Metabolic Syndrome and Atherogenic Progression in ApoE−/− Mice

Evidence-Based Complementary and Alternative Medicine, Volume 2015, Issue 1, 2015., 2015
Cardiovascular Diseases (CVD) represent about 30% of all causes of death worldwide. The development of CVD is related in many cases with the previous existence of metabolic syndrome (MS). It is known that apple consumption has a cardiovascular protecting effect, containing phenolic compounds with antioxidant effect, which are concentrated in the fruit ...

Novel Point Mutations and A8027G Polymorphism in Mitochondrial‐DNA‐Encoded Cytochrome c Oxidase II Gene in Mexican Patients with Probable Alzheimer Disease

International Journal of Alzheimer’s Disease, Volume 2014, Issue 1, 2014., 2014
Mitochondrial dysfunction has been thought to contribute to Alzheimer disease (AD) pathogenesis through the accumulation of mitochondrial DNA mutations and net production of reactive oxygen species (ROS). Mitochondrial cytochrome c‐oxidase plays a key role in the regulation of aerobic production of energy and is composed of 13 subunits.
