NASA’s 21st SpaceX Cargo Mission carries research for Hearts, Airlocks and Asteroids

 

NASA - National Aeronautics and Space AdministrationHouston, TX – The 21st  SpaceX cargo resupply mission that launches from NASA’s Kennedy Space Center in Florida carries a variety of critical research and technology demonstrations to the International Space Station.

The mission represents the first on an upgraded version of the company’s Dragon cargo spacecraft designed to carry more science payloads to and from the space station.

Highlights of the payloads on this mission include:

Technicians work on the Nanoracks Bishop Airlock inside the Space Station Processing Facility at NASA's Kennedy Space Center in Florida on Sept. 29, 2020, preparing the facility for its flight to the International Space Station. The first commercially funded airlock for the space station provides payload hosting, robotics testing, satellite deployment, and more. (NASA/KSC)

Dodging the Roadkill: ‘Tis the Season

 

Dodging the Roadkill - A Biker's JourneyClarksville, TN – It’s early in the morning as I sip fresh coffee and reflect on the past several weeks of my life.  The pain and discomfort.  The constant replay of my accident.  The “what ifs” and “what could’ve, should’ve happened.”

That’s how the brain works.  That’s just human nature.  “Wow, I could have died, maybe I should quit riding, that was close!”

From the moment we were born, we’ve been told “NO” or “Don’t do that.”  We’re taught that we can’t and not “yes you can.” I’m guessing the older we get the more we realize that life comes at you fast and you just have to take it as it comes and enjoy it to the fullest.  If that means I’m a biker, understanding the risks and willing to conclude that this is how I might go out, then so be it.

American Heart Association says High Blood Pressure Treatment may slow Cognitive Decline

 

American Heart AssociationNew Orleans, LAHigh blood pressure appears to accelerate cognitive decline among middle-aged and older adults and treating high blood pressure may slow down the process, according to a preliminary research presented at the American Heart Association’s Hypertension 2019 Scientific Sessions.

The findings are important because high blood pressure and cognitive decline are two of the most common conditions associated with aging, and more people are living longer worldwide.

American Stroke Association says Working before and after Stroke is good for Brain Health

 

American Stroke Association - American Heart AssociationLos Angeles, CA – Adult stroke patients who are employed prior to and after suffering strokes are more likely than unemployed adults to have healthier minds two years post stroke, according to preliminary research presented at the American Stroke Association’s International Stroke Conference 2018, a world premier meeting dedicated to the science and treatment of cerebrovascular disease for researchers and clinicians.

Those who work after stroke also seem to benefit with better long-term cognitive status than those who don’t. (American Heart Association)

American Heart Association says Brain Stimulation plus Adult Neural Stem Cells may speed Stroke Recovery

 

American Heart AssociationLos Angeles, CA – Electrically stimulating implanted adult stem cells may someday speed stroke recovery, according to preliminary research presented at the American Stroke Association’s International Stroke Conference 2018, a world premier meeting dedicated to the science and treatment of cerebrovascular disease for researchers and clinicians.

Stem cell injections are already being studied in people who are slow to recover after an ischemic stroke (clot-caused stroke).

American Heart Association gives Seven steps to keep your Brain Healthy from Childhood to Old Age

 

American Heart Association/American Stroke Association Presidential Advisory

American Heart AssociationDallas, TX – A healthy lifestyle benefits your brain as much as the rest of your body — and may lessen the risk of cognitive decline (a loss of the ability to think well) as you age, according to a new advisory from the American Heart Association/American Stroke Association.

Both the heart and brain need adequate blood flow, but in many people, blood vessels slowly become narrowed or blocked over the course of their life, a disease process known as atherosclerosis, the cause of many heart attacks and strokes.

American Heart Association reports Brain Activity may be predictor of Stress-Related Cardiovascular Risk

 

American Heart Association Rapid Access Journal Report

American Heart AssociationDallas, TX – The brain may have a distinctive activity pattern during stressful events that predicts bodily reactions, such as rises in blood pressure that increase risk for cardiovascular disease, according to new proof-of-concept research in the Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.

The new research, the largest brain-imaging study of cardiovascular stress physiology to date, introduced a brain-based explanation of why stress might influence a person’s heart health.

American Heart Association says quitting statins after stroke may raise risk of another stroke

 

American Heart AssociationDallas, TXStroke patients who stopped taking statin drugs three to six months after a first ischemic stroke, the type caused by narrowed arteries, had a higher risk of a having another stroke within a year, according to new research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.

Researchers also found that discontinuing statin drugs, which lower cholesterol, between three and six months after a first ischemic stroke was linked to higher risk of death and hospitalization among the patients in the study.
