Aging

The thyroid gland has an important role in regulating the body's metabolism, but researchers say it can also influence mental health. Past research found links between an increased risk of depression and both over- and under-active thyroid glands. Now, a new study in the Journal of Clinical Endocrinology  &  Metabolism has found an association between depression and thyroid activity variations...even within the normal range.


Researchers have created an adult stem cell based method for restoring strength to damaged skeletal muscles in the elderly. 

Skeletal muscles are some of the most important muscles in the body, supporting functions such as sitting, standing, blinking and swallowing. In aging individuals, the function of these muscles significantly decreases.   People lose fifteen percent of muscle mass every single year after the age of 75, a trend that is irreversible. 

Through tracing the signaling pathways of the cells, the researchers determined that during aging, a subpopulation of stem cells begin to express a modification of a protein that inhibits their ability to grow and make new stem cells. 


Survey results related to how men approach old age found that happiness remains relatively stable for some 80 percent of the population, but perceptions of unhappiness – or dealing with "hassles" – tends to get worse once you are about 65-70 years old.

The reasons vary, researchers say, but may be because of health issues, cognitive decline or the loss of a spouse or friends.


Chronic pain diagnoses are easy to obtain. Because it is symptom-based medicine and a subjective ailment, it's difficult to say what is real and what isn't.

In cases where the ailment is psychological, the treatment is also, and a new review paper finds that psychological interventions provide more relief than prescription drugs or surgery, though they are used much less frequently than traditional medical. According to the paper, almost half of American adults suffer from chronic pain, and who are you to tell anyone they are not in pain?


Drinking water with a relatively high concentration of magnesium protects against hip fractures, according to results of a study by the Norwegian Institute of Public Health.  They found that magnesium protects against hip fracture for both men and women. They found no independent protective effect of calcium.  

The study notes that there are considerable variations in the quality of drinking water in Norway. The researchers studied variations in magnesium and calcium levels in drinking water between different areas, as these are assumed to have a role in the development of bone strength.

They wanted to examine whether there was a correlation between magnesium and calcium concentrations in drinking water and the incidence of hip fracture. 


What shapes a man’s life?

To begin: Mom, dad, little Jenny Harrison in the 3rd grade, adolescence, acne, heartache, and the jockstrap.

And then there comes the real trauma, age 60 or so: loss of gluteofemoral adipose tissue.

As in:

Sagging of the butt

Collapse of the “gluteo-pecs”

and even...

Disappearance of the “back package.”

You know what I’m talking about. It’s that age-related reworking of your once-marvelous physique, when we replace pecs with moobs, 6-pac abs with a two-liter jug and slim leg Levy’s for old time beltless-wear.

Here is how I found out about it:

Tailor: “What is going on back here? Looks like...diapers. Pampers!”

Me: “What do you mean?”

With any pesticide, over-use can have harmful effects on the environment. 

DDT has not been used in America for over four decades but Rutgers scholars say that exposure to DDT may also increase the risk and severity of Alzheimer's disease in some people, particularly those over the age of 60. 


World War II had consequences for continental Europeans. Living in a war-torn country increased the likelihood of a number of physical and mental problems later in life, according to a paper by economists. 


When you think of treating urinary incontinence in senior women, what is the first thing that comes to mind?

Probably not dancing. But maybe it will work, and it sounds like fun. 

For a study of potential benefits of dancing (and virtual reality), researchers added a series of dance exercises via a video game console to a physiotherapy program for pelvic floor muscles. The results of the small study (24 participants) was a greater decrease in daily urine leakage than for the usual program (so, an improvement in effectiveness) as well as no dropouts from the program and a higher weekly participation rate (an increase in compliance). 


Medical researchers have found a way to reverse a cause of aging in animals - and it doesn't involve starvation. 

The work relates to mitochondria, which are our cells' battery packs and give energy to carry out key biological functions, and a series of molecular eventsthat  enable communication inside cells between the mitochondria and the nucleus. As communication breaks down, aging accelerates.
