Why Being An Optimist Is Good For Your Heart
(CNN) — Looking on the bright side could save your life. People who look at life from a positive perspective have a much stronger shot at avoiding death from any type of cardiovascular risk than pessimistic people, according to a new meta-analysis of nearly 300,000 people published Friday in the medical journal JAMA. “We observed that an optimist had about a 35% lower risk of major heart complications, such as a cardiac death, stroke or a heart attack, compared to the pessimists in each of these studies,” said cardiologist Dr. Alan Rozanski, a professor of medicine at the Icahn School of Medicine at Mount...

Impaired Activity of Ryanodine Receptors Contributes to Calcium Mishandling in Cardiomyocytes of Metabolic Syndrome Rats
Conclusion Principal findings of this work are that abnormal Ca2+ transient amplitude, contractile dysfunction; and impaired relaxation of MetS cardiomyocytes underlies intrinsic dysfunctional RyR2 and SERCA pump. Abnormal activity of RyRs was evidenced by its decreased ability to bind [3H]-ryanodine. Although the MetS condition does not modify RyR2 protein expression, its phosphorylation at Ser2814 is decreased, which impairs its capacity for activation during ECC. The dysfunctional RyRs, together with a decreased activity of SERCA pump due to decreased Thr17-PLN phosphorylation suggest a downregulation of CaMKII in MetS...

Spacing out after staying up late? Here ’s why
Ever sleep poorly and then walk out of the house without your keys? Or space out while driving to work and nearly hit a stalled car?A new study led by UCLA ’sDr. Itzhak Fried is the first to reveal how sleep deprivation disrupts brain cells ’ ability to communicate with each other. Fried and his colleagues believe that disruption leads to temporary mental lapses that affect memory and visual perception. Their findings are published online today by Nature Medicine.“We discovered that starving the body of sleep also robs neurons of the ability to function properly,” said Fried, the study’s senior author, a profess...

Decrease the Symptoms of Sleep Apnea
by Phil Hardesty New research is showing that exercise not only helps the quality of our sleep, but it can improve conditions such as obstructive sleep apnea, or OSA. What is OSA? Obstructive sleep apnea is a condition where a person's breathing frequently pauses during sleep. One of the most noticeable sign of OSA is snoring. Other signs and symptoms of OSA are: Excessive daytime fatigue and sleepiness Observed episodes of breathing cessation during sleep Abrupt awakenings accompanied by shortness of breath Awakening with a dry mouth or sore throat Awakening with chest pain Sudden waking with gasping for breath Mornin...

We Are Our Shadows
The same year the Dalai Lama won the Nobel Peace Prize, 1989, I had my first panic attack. It was my freshman year in college and in the midst of hip-hop, frozen yogurt and scrunchies, I was celebrating independence from my parents for the first time but struggling academically. I had never defined myself as anxious, nervous or worried. Instead I was the girl who doesn't worry about anything. That's how my family had always described me, and I played the part well. As I stood in the emergency room breathing into a bag, doctors urging me to go on medication for my anxiety, I began to question my own sanity. These panic att...
