For decades we’ve been told that stress can kill you, that happy people live longer and that hours in the gym will keep you healthy. Now researchers have turned this kind of long-cherished conventional wisdom on its head. The new mantra: Stress can be good for you. Serious people may live longer than those with sunny dispositions. The treadmill may not hold the key to longevity.
These conclusions come from a unique study, which followed 1,500 Californians across eight decades. The study is described in a new book, “The Longevity Project.” Study co-author Leslie Martin says that some of the new results surprised both her and her co-author, Howard Friedman.
So, if what we’ve been told isn’t true, what can we do to live a long life? Below are eight suggestions gleaned from the longevity study. Read more…
Scientist had reviewed several theories about the Camphor in the vapor rub might improve symptoms, including providing a sensation of improved nasal airflow.
Camphor rightly emphasize the potential benefit of improved sleep for both the children and the parents.
As a result there is an improvement in symptoms may be entirely the result of perception — perception by the child of improved airflow and improved parental perception of how severe the symptoms were because the parent slept better.
Whatever the mechanism is, the use of vapor rub would appear to offer a potential intervention for parents frustrated by URI symptoms. Read more…
Researchers are working upon a universal blood product that will be able to remove the requirement of matching blood groups prior to transfusion.
Maryam Tabrizian and colleagues from McGill University in Canada note that blood transfusions require a correct match between a donor and the recipient’s blood.
This can be a tricky proposition given that there are 29 different red blood cell types, including the familiar ABO and Rh types, reports the journal Biomacromolecules.
The wrong blood type can provoke serious immune reactions that result in organ failure or death, so scientists have long sought a way to create an all-purpose red blood cell for transfusions that doesn’t rely on costly blood typing, according to a McGill release.
To develop this “universal” red blood cell, the scientists discovered a way to encase living, individual red blood cells within a multilayered polymer shell.
The shell serves as a cloaking device, they found, making the cell invisible to a person’s immune system and able to evade detection and rejection.
Oxygen can still penetrate the polymer shell, however, so the red blood cells can carry on their main business of supplying oxygen to the body.
“The results of this study mark an important step toward the production of universal RBCs,” the study says.
