Fast food makes the immune system more aggressive in the long term

Thu, 11 Jan 2018 05:00:00 +0100

(University of Bonn) The immune system reacts similarly to a high fat and high calorie diet as to a bacterial infection. This is shown by a study led by the University of Bonn. Unhealthy food seems to make the body's defenses more aggressive in the long term. Even long after switching to a healthy diet, inflammation towards innate immune stimulation is more pronounced. These changes may be involved in the development of arteriosclerosis and diabetes. (Source: EurekAlert! - Biology)

Long-lasting adaptations of the innate immune system through the bone marrow

Thu, 11 Jan 2018 05:00:00 +0100

(Radboud University Nijmegen) The immune system not only detects and destroys pathogens such as microbes but also plays a role in the onset of diseases such as arteriosclerosis. Scientists from Radboud university medical center, Bonn, Dresden and Pennsylvania, studied a new mechanism that regulates the immune system's functioning. They discovered that cholesterol inhibitors may prevent infections, that a high-fat Western diet can have a long-lasting effect on our immunity and that even our stem cells can be disrupted.

Ra Medical CEO Irwin aims for Feb 2018 IPO

Thu, 24 Aug 2017 17:30:41 +0100

In May, Ra Medical received a nod from the FDA for its Dabra arteriosclerosis laser, clearing it for use in the US. It was a decision the company had been waiting on for approximately 3 years, CEO Dean Irwin told MassDevice.com in an interview, and signaled a significant shift forward. “In 2014, we submitted to the FDA, and here in 2017, just on May 24th, we received the go ahead to begin marketing in the United States,” Irwin said.

New unknown risk factor for arteriosclerosis identified

Mon, 09 Jan 2017 14:30:17 +0100

Following a blood infection, the first class of antibodies produced by the immune system are IgM antibodies. They form the " vanguard " of the immune response, before other cells are activated to fight the infection. Some people are deficient or completely lack these antibodies, so that they develop congenital immune deficiency. Researchers have now discovered how this deficiency can also lead to an increased risk of arteriosclerosis and consequently even to serious cardiovascular diseases.

Smokers have higher lifetime risk of abdominal aortic aneurysm

Thu, 17 Nov 2016 19:59:02 +0100

This study adds to the literature by reporting AAA lifetime risk from a community-based cohort with long follow-up,” Tang told Reuters Health by email. The researchers used data from more than 15,000 middle-aged people who were at risk of developing AAA based on an initial assessment between 1987 and 1989. The participants made three subsequent visits for exams and assessments through 1998. Nearly 6,000 people were still alive between 2011 and 2013 and underwent an ultrasound exam at a fifth assessment visit then. Over the 22-year follow-up period, there were 590 diagnosed, ruptured or repaired AAAs. In 2011, the ultrasound scans found 75 more cases that had gone undetected. Based on these results, researchers calculated that for participants who began the study, 1 in 17 would go on to d...

Control Inflammation and “Turn Off” Disease-Causing Genes

Tue, 15 Sep 2015 21:26:46 +0100

The single most important thing you can do to prevent premature aging is to control inflammation. Inflammation is the body’s effort to heal itself. But too much produces disease. In fact, most of the diseases associated with aging are essentially inflammatory diseases. That includes cancer, heart disease, arthritis, arteriosclerosis, Alzheimer’s disease and diabetes. And the truth is that we’re all inflamed thanks to a modern diet that includes inflammation-friendly ingredients like sugar, cheap vegetable oils, and refined carbohydrates. Most doctors are not educated in the role of nutrition in disease. And they often recommend the bland buzz phrase of eating a “balanced diet.” But that’s usually just a balance of junk, like breads, cereals, and other pr...



Sleep Problems May Hint At Future Heart Disease Risk

Thu, 10 Sep 2015 21:36:07 +0100

By Kathryn Doyle (Reuters Health) - Adults who get too much or too little sleep may have the beginnings of “hardening" of the arteries, which can be an early sign of heart disease, according to a new study. “Many people, up to one third or one fourth of the general population, suffer from inadequate sleep – either insufficient duration of sleep or poor quality of sleep,” said co-lead author Dr. Chan-Won Kim of Kangbuk Samsung Hospital of Sungkyunkwan University School of Medicine in Seoul, South Korea. Several studies have linked inadequate sleep with an increased risk of heart attack and stroke, but other conditions like depression or obesity could influence this association, Kim told Reuters Health by email. “In contrast, we studied if sleep of inadequate du...

Save Your Brain

Wed, 06 May 2015 18:28:41 +0100

Alzheimer’s is one of the most devastating and dreaded diseases I’m confronted with at my South Florida anti-aging clinic. And because I’m based in a part of the country that’s a major retirement Mecca, I see more seniors than the average American physician – and proportionally more Alzheimer’s sufferers. Many patients fear Alzheimer’s more than cancer or any other debilitating disease. They’re terrified of this cruel, progressive and degenerative illness that attacks the brain, steals memory, confuses thinking, and can turn even the most intelligent and achieving adults into mental infants. Mainstream doctors will tell you there’s no way to reverse this dreaded scourge. And they’ll tell you that only expensive Big Pharma drugs have a...

Why You Should Avoid Statins

Tue, 03 Feb 2015 19:22:19 +0100

At my anti-aging clinic, I continue to wage war against what I call the “medical-industrial complex.” And I do it for one reason only – I care more about my patients than I do about profits. Big Pharma clearly takes the opposite view. And now it seems these pharmaceutical behemoths won’t be happy until every man, woman and child is popping anti-cholesterol pills. Researchers at Duke University recently issued a report recommending that even children and people as young as 30 should be on statins, if they have just slightly elevated cholesterol levels.1 And why wouldn’t researchers at Duke recommend such a thing? Guess where great chunks of their funding comes from … yep, Big Pharma. That research team at Duke University includes two doctors who have admitted to ...



Sunshine and Telomeres

A warm sunny day … what could feel better? Yet the warm sun on our skin that we all crave gets a lot of bad press from the medical establishment. Far from being a source of illness that will kill you before your time, the sun is your best hope to live longer and prevent illness. Did you know, for example, that people living in places that get more of the sun’s UV radiation have the lowest incidence of cancer?1 That doesn’t mean sunlight lowers the “risk” of getting cancer. Getting more sunlight keeps people from actually getting cancer. Studies show sunlight prevents skin cancer, prostate2 cancer, lung3 cancer, colorectal4 cancer… and it lowers rates of leukemia, breast cancer, bladder cancer and lymphoma. I could list many more.

Dare to Be 100: Fat, Carbs, Calories

These three items were the centerpiece of my early science life. I wrote my honors thesis at Williams College about arteriosclerosis which at that time was considered to be heavily influenced by dietary fat. Then after medical school I entered a wonderful time of life learning much about F, Cs, and Cs. The 1960s overflowed. The high point of those years was those spent in the intellectual and physical embrace of two multi-million dollar research grants from the NIH. The first dealt with the control of cholesterol synthesis, and the second "The Effect of Diet on the Metabolism of Fat In Man." This second grant supported a five-bed metabolic study unit at the Lankenau Hospital in Overbrook, Pennsylvania. The study beds were staffed with full nutritional and biochemical backup as we fed spec...

Researchers Identify Target To Prevent Hardening Of Arteries

Mon, 20 May 2013 08:00:00 +0100

The hardening of arteries is a hallmark of atherosclerosis, an often deadly disease in which plaques, excessive connective tissue, and other changes build up inside vessel walls and squeeze off the flow of oxygen-rich blood throughout the body. Now, researchers at Sanford-Burnham Medical Research Institute have described the molecular and cellular pathway that leads to this hardening of the arteries - and zeroed in on a particularly destructive protein called Dkk1. Their study was published online today by Arteriosclerosis, Thrombosis, and Vascular Biology... (Source: Health News from Medical News Today)

Jekyll into Hyde: Breathing auto emissions turns HDL cholesterol from 'good' to 'bad'

Wed, 15 May 2013 20:00:00 +0100

Academic researchers have found that breathing motor vehicle emissions triggers a change in high-density lipoprotein (HDL) cholesterol, altering its cardiovascular protective qualities so that it actually contributes to clogged arteries.    In addition to changing HDL from "good" to "bad," the inhalation of emissions activates other components of oxidation, the early cell and tissue damage that causes inflammation, leading to hardening of the arteries, according to the research team, which included scientists from UCLA and other institutions.   The findings of this early study, done in mice, are available in the online edition of the journal Arteriosclerosis, Thrombosis and Vascular Biology, a publication of the American Heart Association, and will appear in the journal's Ju...

RAGE Splicing Variants in Mammals

Tue, 01 Jan 2013 05:00:00 +0100

The receptor for advanced glycation end products (RAGE) is a multiligand receptor of environmental stressors which plays key roles in pathophysiological processes, including immune/inflammatory disorders, Alzheimer’s disease, diabetic arteriosclerosis, tumorigenesis, and metastasis. Besides the full-length RAGE protein in humans nearly 20 natural occurring RAGE splicing variants were described on mRNA and protein level. These naturally occurring isoforms are characterized by either N-terminally or C-terminally truncations and are discussed as possible regulators of the full-length RAGE receptor either by competitive ligand binding or by displacing the full-length protein in the membrane. Accordingly, expression deregulations of the naturally occurring isoforms were supposed to have s...
