DISPOSING of corpses can be tricky. Bury them in a shallow grave and hungry animals are liable to dig them up. Our body faces a somewhat similar problem when it comes to disposing of unwanted substances. One of the ways the liver purifies blood is by adding the equivalent of a “chuck this out” label to molecules, but this label is made of a kind of sugar – and the bugs in our gut have a sweet tooth. Some produce a special enzyme that allows them to cut off the sugar and eat it, which often results in compounds being recycled within the body rather than disposed of.
Back in the 1980s, Richard Jefferson used the enzyme to develop a powerful technique now relied upon by thousands of genetic engineers around the world. At the same time, he was intrigued by the enzyme’s normal role. Its recycling effect helps determine the blood levels of many compounds, including important substances such as sex hormones. Jefferson realised that the bacteria within us, far from being passive hangers-on, must affect us in profound ways. Continue reading The Hologenome: A new view of Evolution
Giving a keynote lecture, Dr Thacker advised delegates to move away from purely mechanical-based therapies for back pain patients, and become more aware of the role of neuro-immnunology in relation to pain.
“Traditional physiotherapy has based its management of back pain on anatomical, tissue-based principles and biomechanics”, said Dr Thacker. Continue reading Let go of outdated paradigms and stop dwelling on Biomechanical tissue-based models when treating Back Pain.
Doctors have warned of a “lack of knowledge” about the dangers of mixing some medications with grapefruit.
The fruit can cause overdoses of some drugs by stopping the medicines being broken down in the intestines and the liver.
The researchers who first identified the link said the number of drugs that became dangerous with grapefruit was increasing rapidly.
They were writing in the Canadian Medical Association Journal.
The team at the Lawson Health Research Institute in Canada said the number of drugs which had serious side effects with grapefruit had gone from 17 in 2008 to 43 in 2012. Continue reading Grapefruit causes dangerous interactions with Medication
Fibromyalgia is a disorder characterised by muscle pain, fatigue, and other symptoms. People with fibromyalgia have chronic widespread pain, as well as “tender points” on areas of the body, which hurt when slight pressure is applied. Although exercise appears to be an important part of fibromyalgia treatment, many people with fibromyalgia need medication to control symptoms and are unable to maintain muscle strength, flexibility, and overall fitness. Continue reading Tai Chi Benefits Patients With Fibromyalgia
THERE’S a fuzz in my brain and an ache in my gut. My legs are leaden and my eyesight is blurry. But I have only myself to blame. Besides, I have been assured that these symptoms will pass. Between 10 days and three weeks from now, my body will adjust to the new regime, which entails fasting for two days each week. In the meantime, I just need to keep my eyes on the prize. Forget breakfast and second breakfast, ignore the call of multiple afternoon snacks, because the pay offs of doing without could be enormous.
Fasting is most commonly associated with religious observation. It is the fourth of the Five Pillars of Islam. Buddhists consider it a means to practise self-control and advocate abstaining from food after the noon meal. For some Christians, temporary fasts are seen as a way of getting closer to God. But the benefits I am hoping for are more corporeal.
A new surge of interest in fasting suggests that it might indeed help people with cancer. It could also reduce the risk of developing cancer, guard against diabetes and heart disease, help control asthma and even stave off Parkinson’s disease and dementia. Many of the scientists who study fasting practise what they research, and they tell me that at my age (39) it could be vital that I start now. “We know from animal models,” says Mark Mattson at the US National Institute on Aging, “that if we start an intermittent fasting diet at what would be the equivalent of middle age in people, we can delay the onset of Alzheimer’s and Parkinson’s.” Surely it’s worth a try? Continue reading Intermittent Fasting by Emma Young
In this fiery and funny talk, New York Times food writer Mark Bittman weighs in on what’s wrong with the way we eat now (too much meat, too few plants; too much fast food, too little home cooking), and why it’s putting the entire planet at risk.
Findings of a recent trial show that women aged over 65 who received omega-3 fatty acids gained almost twice as much muscle strength following exercise than those taking olive oil.
A larger trial is planned to confirm these findings and to determine why muscle condition improves.
The findings are being presented at the British Science Festival in Aberdeen.
Some studies have linked diets high in omega-3 – commonly found in oily fish such as mackerel and sardines – to potential health benefits, such as a lower risk of coronary heart disease.
During healthy ageing, muscle size is reduced by 0.5-2% per year.
This process – known as sarcopenia – can result in frailty and immobility in old people.
Little is known about the prevalence of sarcopenia in the UK, but data from the US shows that 25% of people aged 50-70 have sarcopenia and this increases to more than half of those aged over 80 years. Continue reading Fish Oils help stop muscle atrophy in the Elderly
