This graphic shows the effects of mental stress on psychophysiological domains, myocardial ischemia, and outcomes in men and women.
Men and women have different cardiovascular and psychological reactions to mental stress, according to a study of men and women who were already being treated for heart disease. The study, published today in the Journal of the American College of Cardiology, looked at 56 women and 254 men diagnosed with heart disease enrolled in a larger REMIT study of the impact of the medication escitalopram on heart disease induced by mental stress.

After undergoing baseline testing, participants carried out three mentally stressful tasks - a mental arithmetic test, a mirror tracing test, and an anger recall test - followed by a treadmill exercise test. During mental stress tasks and rest periods between tests, researchers conducted echocardiography to study changes in the heart, took blood samples, and measured blood pressure and heart rate.

Researchers from the Duke Heart Center found that while men had more changes in blood pressure and heart rate in response to the mental stress, more women experienced myocardial ischemia, decreased blood flow to the heart. Women also experienced increased platelet aggregation, which is the start of the formation of blood clots, more than men. The women compared with men also expressed a greater increase in negative emotions and a greater decrease in positive emotions during the mental stress tests.

Leading Neuroscientist: "ADHD is not a real disease"

One of the world's leading pediatric neuroscientists, Dr. Bruce D. Perry, M.D., Ph.D, recently stated publicly that Attention Deficit/Hyper-Activity Disorder (ADHD) is not 'a real disease,' and warned of the dangers of giving psycho-stimulant medications to children.

Speaking to the Observer, Dr. Perry noted that the disorder known as ADHD should be considered a description of a wide range of symptoms that many children and adults exhibit, most of which are factors that everyone of us displays at some point during our lives.
"It is best thought of as a description. If you look at how you end up with that label, it is remarkable because any one of us at any given time would fit at least a couple of those criteria," he said.

Comment: There is a connection between diet and hyperactivity in children. Read the following articles for more information about how ADHD symptoms can be reduced by a change in diet:
According to a new study by Dutch scientists, restricting the range of foods fed to children suffering from ADHD can "significantly improve" their disrupting behavior and can prove a standard treatment for such kids.
A new study from Perth's Telethon Institute for Child Health Research shows an association between ADHD and a 'Western-style' diet in adolescents.

Leader of Nutrition studies at the Institute, Associate Professor Wendy Oddy, said the study examined the dietary patterns of 1800 adolescents from the long-term Raine Study and classified diets into 'Healthy' or 'Western' patterns.

Dr Oddy said:
"We suggest that a Western dietary pattern may indicate the adolescent has a less optimal fatty acid profile, whereas a diet higher in omega-3 fatty acids is thought to hold benefits for mental health and optimal brain function.

"It also may be that the Western dietary pattern doesn't provide enough essential micronutrients that are needed for brain function, particularly attention and concentration, or that a Western diet might contain more colors, flavors and additives that have been linked to an increase in ADHD symptoms.

Dallas nurse tests positive for Ebola

A health care worker at Texas Health Presbyterian Hospital in Dallas who had "extensive contact" on "multiple occasions" with Thomas Eric Duncan has tested positive for Ebola after a preliminary test, officials said Sunday.

Confirmatory testing is being conducted by the Centers for Disease Control and Prevention in Atlanta. Test results are expected to be announced later in the day.

The patient is a nurse, an official who is familiar with this case told CNN.

She was involved in Duncan's second visit to the hospital, when he was admitted for treatment, and was wearing protective gear as prescribed by the CDC: gown, gloves, mask and shield, Texas Health Resources chief clinical officer Dan Varga said.

She is in stable condition, Varga said. Duncan, the first person to be diagnosed with Ebola in the United States, died Wednesday.

The Ketogenic Diet - An Overview

Ketogenic diet helps weight loss, epilepsy, MS, Alzheimer's and starves cancer


Samantha Chang - authoritarian follower, DOJ wannabe - puts profit before people
The author of this article, and a few other articles hosted on Sott.net, Samantha Chang, recently demanded that Sott.net stop republishing her articles (all of which are on the Ketogenic diet), on pain of "bad things happening" to us (see email below).

Like a good authoritarian follower, Ms. Chang backed up her 'threat' with a symbol of the totalitarian state under which she exists - an image of a United States Dept. of Justice wallet (see below), which seems to suggest that she has perhaps internalized the fascistic ideology of the police state that is the US of A.

Many writers have published information on the benefits of a Ketogenic diet, including research conducted by Sott.net that was made freely available to all. Ms. Chang, however, obviously does not subscribe to the idea of the free flow of vitally important information in an age of massive information control and subversion.

Given that Ms. Chang is obviously more interested in personal profit rather than the dissemination of information that could help many people, we will no longer be carrying her articles. In chasing after self-aggrandizement at the expense of helping others, she has clearly aligned herself with the fundamentals of our pathologically narcissistic global society.

Suspect Ebola cases popping up all over the globe - global panic just beginning

A person in Quebec with symptoms of the Ebola virus is being treated in a hospital in Abitibi-Témiscamingue. According to the regional health and social services agency, the patient was recently in contact with people who may have been exposed to Ebola. "I have to highlight that our suspicion is very weak," said Dr. Éric Lampron-Goulet, a regional public health official. "We did a test out of precaution." Lampron-Goulet said the patient has a fever and that, combined with having contact with West African travelers, is sufficient to merit tests. He said the patient has been isolated while the tests are underway. Tests have been sent to the public health laboratory in Quebec and results are expected within 24 to 36 hours. He also said Quebec's health system is prepared for Ebola is following the procedure for treating suspicious cases. - CBC

Brazil:

Fears are growing that the deadly Ebola virus has hit a new continent as a missionary in Brazil undergoes tests for the infection. If the Brazilian case is confirmed, it would mean the disease has spread to South America for the first time. The suspected patient is a 47-year-old man from Guinea, one of the African countries that have been ravaged by the disease. He has been described in local media as a missionary and he was taken in an air force plane from the southern state of Parana to the National Infectious Disease Institute in Rio de Janeiro on Friday morning. It came after he arrived at a health centre in the town of Cascavel with a fever the previous afternoon. The health ministry said today that the patient was 'in good shape' and his slight fever had now subsided. Minister Arthur Chioro noted that the patient had been in Brazil for the maximum incubation period for the Ebola virus of 21 days. The result of a test for the virus should be available by early Saturday, he said. - Mail

Czechoslovakia:

Czech Republic registers its first case of suspected Ebola, who returned from Liberia 22 days ago, Czech chief sanitary officer Vladimir Valenta said Thursday. The man, 56, has fever but no other Ebola symptoms, and was in isolation at Prague's Na Bulovce hospital, Xinhua quoted Valenta as saying. (Read: Ebola facts - frequently asked questions (FAQ))'As the only symptom has been fever so far, we hope that it might be another disease, for instance, malaria,' he said, adding that all people whom the patient has met since his return are being checked. Hospital sources said the results of tests conducted are expected Friday. - Health Site

Ebola virus and dogs: Where do we stand?

The recent euthanasia of a dog owned by a Spanish nursing assistant infected with Ebola virus has raised much concern about the canine role in Ebola virus transmission and the risks dogs may pose to humans. As is common with emerging diseases, there are many gaps in our knowledge - and these gaps can create fear.

Comment: Unfortunately, when it comes to zoonotic diseases there are more questions than answers. What's for sure, where there is a high rate of mutation, there is a wide range of surprises.

Ebola could be airborne and can be spread even without symptoms, say virus researchers

coughing man

The chorus of U.S. health officials constantly reassuring the public that Ebola can't transmit through the air is quickly tailing off, as virologists and other disease experts say "not so fast." Health experts know very little about the nature of the Ebola strain now in circulation, they say, and it appears as though the current iteration of the disease is much more virulent than previously believed.

Dr. C.J. Peters, a former researcher who worked with the Centers for Disease Control and Prevention (CDC) to study Ebola's transmissibility in humans, is just one of many who now say that airborne transmission of Ebola can't be ruled out as an impossibility. There simply isn't enough data to suggest otherwise, he says.

Mechanism that repairs brain after stroke discovered

© Lund University
A stroke is caused by a blood clot blocking a blood vessel in the brain, which leads to an interruption of blood flow and therefore a shortage of oxygen. Many nerve cells die, resulting in motor, sensory and cognitive problems.
A previously unknown mechanism through which the brain produces new nerve cells after a stroke has been discovered at Lund University and Karolinska Institutet in Sweden. The findings have been published in the journal Science.

A stroke is caused by a blood clot blocking a blood vessel in the brain, which leads to an interruption of blood flow and therefore a shortage of oxygen. Many nerve cells die, resulting in motor, sensory and cognitive problems.

The researchers have shown that following an induced stroke in mice, support cells, so-called astrocytes, start to form nerve cells in the injured part of the brain. Using genetic methods to map the fate of the cells, the scientists could demonstrate that astrocytes in this area formed immature nerve cells, which then developed into mature nerve cells.

"This is the first time that astrocytes have been shown to have the capacity to start a process that leads to the generation of new nerve cells after a stroke," says Zaal Kokaia, Professor of Experimental Medical Research at Lund University.

The scientists could also identify the signalling mechanism that regulates the conversion of the astrocytes to nerve cells. In a healthy brain, this signalling mechanism is active and inhibits the conversion, and, consequently, the astrocytes do not generate nerve cells. Following a stroke, the signalling mechanism is suppressed and astrocytes can start the process of generating new cells.

"Interestingly, even when we blocked the signalling mechanism in mice not subjected to a stroke, the astrocytes formed new nerve cells," says Zaal Kokaia.

A Briton with symptoms of Ebola has died in Macedonia, local authorities said. The hotel in Skopje where he was staying has been sealed off, while another Briton and hotel staff are being kept inside to prevent possible spreading of infection.

According to Macedonian authorities the man came to Skopje from London on October 2 and was taken to hospital on Thursday where he died several hours later.

The man reportedly suffered from fever, vomiting and internal bleeding. His condition deteriorated rapidly, Dr. Jovanka Kostovska of the ministry's commission for infectious diseases said.

"These are all symptoms of Ebola, which raises suspicions with this patient," Kostovska told a news conference.
