“These changes reduce the number of species capable of surviving in the intestinal environment, reducing overall diversity. This less diverse microbiota is less able to crowd-out dangerous microbes such as coliform pathogens.”

“A healthy mucus layer forms large droplets, while a dysfunctional mucus layer produces droplets that aerosolize into many smaller infectious droplets. Mucus structure and composition are influenced by age, environment, disease, and the microbiota.”

“These microorganisms produce a variety of polymer substances that form an extracellular matrix that has a sticky texture and protects the inside layers of the biofilm from the external environment, including antibiotic treatments.”

“A fundamental component of the inflammaging process is immune system recognition of metabolic, hormonal, and immune stimuli (such as chronic infections or age-related changes in the gut microbiota), thereby promoting an inflammatory environment.”

“There are biologically plausible explanations for the association between developmental vitamin D deficiency and an increased risk of offspring ADHD. Early pregnancy is a critical period for fetal brain development, which is a complex process influenced by genetics and the in utero environment.”

“Rather than pointing to a single cause or risk factor, biological age measures may capture the cumulative effects of many influences that shape the body's internal environment over time, including metabolic health, inflammation, sleep, chronic stress, environmental exposures, diet, obesity, physical activity, and social conditions.”

“Along with other metals such as copper, iron, and magnesium, zinc is essential for balancing oxidative and reductive reactions in the cellular environment. One enzyme, copper-zinc superoxide dismutase, neutralizes hydrogen peroxide radicals by accepting an electron at its copper site.”

“The original trial enrolled 33 adults with newly diagnosed astrocytoma, a brain tumor named for its resemblance to astrocytes, star-shaped cells that help support nerve cells by supplying nutrients and maintaining a healthy environment around them.”

“These antioxidant compounds eventually end up in the urine, which is temporarily stored in the bladder prior to elimination, providing a unique environment in which to study the effects of sulforaphane and its metabolic byproducts on bladder tissue.”

“Retinal ganglion cells called intrinsically photosensitive melanopsin retinal ganglion cells (IpRGCs) assess how bright the environment is and use this to set the circadian clock – ensuring that we’re alert during the day and that we get sleepy at night.”
