Telangiectasias (spider veins) most commonly seen around the nose, cheeks and ...
The wavelength of the light source needs to be appropriate for exciting the photosensitizer to produce radicals and/or reactive oxygen species. These are free radicals (Type I) generated through electron abstraction or transfer from a substrate molecule and highly reactive state of oxygen known as singlet oxygen (Type II). PDT is a multi-stage ...
“The rise in rates of these conditions are the by-products of a longer life span,” says Nicole Ehrhart, V.M.D., the director of Colorado State University’s Columbine Health Systems Center ...
Pro-oxidants are chemicals that induce oxidative stress, either by generating reactive oxygen species or by inhibiting antioxidant systems. [1] The oxidative stress produced by these chemicals can damage cells and tissues, for example, an overdose of the analgesic paracetamol (acetaminophen) can fatally damage the liver, partly through its production of reactive oxygen species.
An anti-aging therapy led to an extension of life by 25% in a new animal study. The treatment significantly decreased cancer-related deaths and reduced various diseases associated with fibrosis ...
The free radical theory of aging states that organisms age because cells accumulate free radical damage over time. [1] A free radical is any atom or molecule that has a single unpaired electron in an outer shell. [2] While a few free radicals such as melanin are not chemically reactive, most biologically relevant free radicals are highly ...
Aging researchers explain what inflammaging is and how to manage chronic inflammation as you age.
"Ozempic face is more likely to occur in middle-aged and older people," Dr. Mattingly says. "Many do not show obvious signs of aging until the fat loss. That's when the skin gets lines and sags ...
