Epigenetics: How exercise and other lifestyle changes can affect your DNA

© Mun Fitness Blog
Exercising literally changes your DNA expression
We all know that exercise can make us fitter and reduce our risk for illnesses such as diabetes and heart disease. But just how, from start to finish, a run or a bike ride might translate into a healthier life has remained baffling.

Now new research reports that the answer may lie, in part, in our DNA. Exercise, a new study finds, changes the shape and functioning of our genes, an important stop on the way to improved health and fitness.

The human genome is astonishingly complex and dynamic, with genes constantly turning on or off, depending on what biochemical signals they receive from the body. When genes are turned on, they express proteins that prompt physiological responses elsewhere in the body.

Scientists know that certain genes become active or quieter as a result of exercise. But they hadn't understood how those genes know how to respond to exercise.

Comment: In addition to exercise, improving your diet and decreasing your stress or managing it properly can have beneficial effects on your DNA.

Exposure to cold reveals 'switch' that controls formation of brown, white fat


Each type of fat may change into the other, depending on the temperature. In particular, cold temperatures may encourage 'unhealthy' white fat to change into 'healthy' brown fat.
The roles that white fat and brown fat play in metabolism is well documented, but new research published in the January 2015 issue of the FASEB Journal presents a new wrinkle: each type of fat may change into the other, depending on the temperature. In particular, cold temperatures may encourage "unhealthy" white fat to change into "healthy" brown fat.

"Fat cells can adopt a range of metabolic phenotypes, depending on physiological conditions and location in the body," said James G. Granneman, Ph.D., a researcher involved in the work from the Center for Integrative Metabolic and Endocrine Research at the Wayne State University School of Medicine in Detroit, MI. "Our long-term goal is to harness this cellular and metabolic flexibility for the treatment of metabolic disorders linked to dysfunctional fat, such as type 2 diabetes."

Comment: Cold therapy enhances immune system function. In this day of superbugs, unending strains of new flu virus and ebola, it only makes sense to do everything possible to strengthen it. Cold therapy is a valuable technique for improving over all health but should be approached in a gradual way. Some helpful articles:

Depression as an allergic and inflammatory reaction

Could depression be a form of 'sickness behaviour'?
Barely a week goes by without a celebrity "opening up" about their "battle with depression". This, apparently, is a brave thing to do because, despite all efforts to get rid of the stigma around depression, it is still seen as some kind of mental and emotional weakness.

But what if was nothing of the sort? What if it was a physical illness that just happens to make people feel pretty lousy? Would that make it less of a big deal to admit to? Could it even put a final nail in the coffin of the idea that depression is all in the mind?

According to a growing number of scientists, this is exactly how we should be thinking about the condition. George Slavich, a clinical psychologist at the University of California in Los Angeles, has spent years studying depression, and has come to the conclusion that it has as much to do with the body as the mind. "I don't even talk about it as a psychiatric condition any more," he says. "It does involve psychology, but it also involves equal parts of biology and physical health."

The basis of this new view is blindingly obvious once it is pointed out: everyone feels miserable when they are ill. That feeling of being too tired, bored and fed up to move off the sofa and get on with life is known among psychologists as sickness behaviour. It happens for a good reason, helping us avoid doing more damage or spreading an infection any further.

It also looks a lot like depression. So if people with depression show classic sickness behaviour and sick people feel a lot like people with depression - might there be a common cause that accounts for both?

Depression: It's not your Serotonin

Millions believe depression is caused by 'serotonin deficiency,' but where is the science in support of this theory?
"Depression is a serious medical condition that may be due to a chemical imbalance, and Zoloft works to correct this imbalance."
Herein lies the serotonin myth.

As one of only two countries in the world that permits direct to consumer advertising, you have undoubtedly been subjected to promotion of the "cause of depression." A cause that is not your fault, but rather; a matter of too few little bubbles passing between the hubs in your brain! Don't add that to your list of worries, though, because there is a convenient solution awaiting you at your doctor's office...

What if I told you that, in 6 decades of research, the serotonin (or norepinephrine, or dopamine) theory of depression and anxiety has not achieved scientific credibility?

You'd want some supporting arguments for this shocking claim.

So, here you go:

Comment: Psychiatrist Dr. Daniel Carlat has said "psychiatry has become a proving ground for outrageous manipulations of science in the service of profit."

Listen to the SOTT podcast Good Science, Bad Science - Psychology and Psychiatry for a lively discussion on this topic:
In this second in our series of shows on the topic of science and its benefits and negative consequences for mankind, we'll be taking a look at the use and abuse of psychiatry and psychology.

From the psychotherapist's chair to anti-depressant drugs and diverse therapeutic modalities, psychiatry and psychology have come up with as many solutions for mental health issues as there are theories of what makes people tick.

While many individuals have benefited from some form of intervention or another, the application of psychological knowledge for propaganda purposes, mind control experiments and pure corporate greed has apparently left most people's psychological health more fragile than ever.

This week, we will attempt to sort the good from the bad and the ugly by 'psychoanalyzing' some of the questionable practices and theories of the mind, and untangle the confusion produced by psychological terminology that frequently overlaps the same basic underlying problems people encounter in our stressful modern world.

Skin fat helps fight infection

Fat cells just under a person's skin may be the first responders to invading bacteria, buying time until the white blood cells arrive at a wound site, according to a new study.

The new findings suggest that the task of fighting infections is not solely the responsibility of the immune system, the researchers said. Moreover, fat cells may fight infections by producing antimicrobial compounds, lab experiments in mice and human fat cells showed.

"That was totally unexpected," study co-author Dr. Richard Gallo, chief of dermatology at the University of California, San Diego School of Medicine, said in a statement. "It was not known that [fat cells] could produce antimicrobials, let alone that they make almost as much" as immune system cells, he said.

Comment: Fat really is a wonderful thing! A high-fat, low-carb diet can reverse obesity and insulin resistance. And cold therapy not only activates brown fat cells, which enhances metabolism, but also boosts the immune system.

Big Pharma deflects responsibility for gruesome antibiotic side effects

A recent ABC news item featured an unfortunate tragedy of a women hospitalized in an intensive care burn unit with Stevens-Johnson syndrome after taking a pharmaceutical antibiotic. This "rare" syndrome is gruesome.

She was placed into intensive care of a burn unit in the University of California Irvine's burn unit, as 70 percent of her body is burning "from the inside out".

Dr. Joshua Zeichner, a dermatology professor at the Mount Sinai Hospital in Manhattan commented to ABC on this issue. "You're not truly burned, but what happens is you have compromised the skin barrier function." In other words, the epidermis separates from the dermis and 2nd and 3rd degree burns and blisters manifest painfully.

Pets may improve social skills of children with autism

Children with autism have stronger social skills when they live with a pet, an MU researcher found.
Dogs, cats and other animals may improve social skills of children with autism.

Dogs and other pets play an important role in individuals' social lives, and they can act as catalysts for social interaction, previous research has shown. Although much media attention has focused on how dogs can improve the social skills of children with autism, a University of Missouri researcher recently found that children with autism have stronger social skills when any kind of pet lived in the home.
"When I compared the social skills of children with autism who lived with dogs to those who did not, the children with dogs appeared to have greater social skills,"
said Gretchen Carlisle, research fellow at the Research Center for Human-Animal Interaction (ReCHAI) in the MU College of Veterinary Medicine.
"More significantly, however, the data revealed that children with any kind of pet in the home reported being more likely to engage in behaviors such as introducing themselves, asking for information or responding to other people's questions. These kinds of social skills typically are difficult for kids with autism, but this study showed children's assertiveness was greater if they lived with a pet."
Pets often serve as "social lubricants," Carlisle said. When pets are present in social settings or a classroom, children talk and engage more with one another. This effect also seems to apply to children with autism and could account for their increased assertiveness when the children are living in a home with pets, Carlisle said.

Comment: It's puzzling why the rates of autism have increased so dramatically during the last decades. It seems more and more likely that there are multiple external factors contributing to autism instead of it just being an accidental genetic neurological condition. Our medical authorities tell us that the high increase of autism is only due to improved and more efficient diagnosis of autism. In the mid '90s, 1 out of 500 children were diagnosed with autism. Now it's about 1 out of 70 children. In the United States, the prevalence of autism has increased 30% in just two years, between 2012 and 2014, according to CDC. Are we supposed to believe that this kind of epidemic growth is happening only because we're able to detect it better? Read these articles to learn more:

Altering your gut bacteria eases anxiety and depression

The plethora of microbes living in the human gut not only affect people's physical health, they may also influence mental health, according to a growing body of research.

Recent studies in animals show that changes in the gut bacteria community appear to make mice less anxious, and also affect levels of the stress hormone cortisol.

In humans, there is some very early evidence of a link between gut bacteria and mental health. A new study from England found that supplements that boost "good" bacteria in the gut (called "prebiotics") may alter the way people process emotional information, suggesting that changes in gut bacteria may have anti-anxiety effects.

Scientists are now interested in studying whether probiotics (strains of good bacteria) or prebiotics (carbohydrates that serve as food for those bacteria) could be used to treat anxiety or depression, or if the substances improve patients' response to psychiatric drugs, said study author Philip Burnet, a researcher in the University of Oxford's department of psychiatry.

Question

Why is it illegal for communities to protect themselves from toxic harm?

The supposed answer to that question is the Supremacy Clause of the US Constitution, Article 6, paragraph 2:
"This Constitution, and the laws of the United States which shall be made in pursuance thereof; and all treaties made, or which shall be made, under the authority of the United States, shall be the supreme law of the land; and the judges in every state shall be bound thereby, anything in the Constitution or laws of any State to the contrary notwithstanding."
By inference, the individual states declare their own supremacy when local communities try to nullify or avoid state statutes.

Keep in mind that the US Constitution enumerates powers granted to the federal government, and reserves all other powers for the states or the people. But this restraint has been trampled on so many times it's barely visible under the tonnage of federal law and regulation.

Comment: Some communities are attempting to make a difference and stand up for the health of its citizens.

Ebola in the UK: New suspected case in Gloucestershire, as Scottish nurse worsens


Great Western Hospital, Swindon
A patient suspected of having the deadly Ebola virus is being transferred to hospital in Swindon, while doctors say Pauline Cafferkey, the Scottish nurse already stricken with the disease, has deteriorated to a critical condition

A new patient displaying symptoms of the deadly Ebola virus is being rushed to hospital as doctors say the Scottish nurse already suffering from the disease has worsened and is now in a critical condition.

Hospital officials said the unnamed new patient was being transferred to hospital in Swindon by specialist ambulance team after being taken ill after returning from West Africa.

The patient, from South Gloucestershire, will undergo tests at the hospital and if necessary be transferred to the specialist quarantine unit in London where nurse Pauline Cafferkey is already being treated.

A spokesman for the Great Western Hospitals NHS Foundation Trust said: "Any suspected patients will be tested for a variety of things. If there was a confirmed Ebola case, they would be transferred to London."
