The Good News About Plant Foods. Over the past few of months there have been a slew of new studies reporting the benefits of plant-based foods.
From berries to broccoli, fruits and vegetables are increasingly being recognized for their health-promoting, disease-fighting, and anti-aging properties! Below is a roundup of the good news about plant foods…including 10 new studies from the first quarter of 2012 alone! Berries - Berries are without a doubt one of the most nutritious and delicious foods on the planet! Nearly all berries are high in vitamin C and fiber and low in calories, making them an excellent, nutrient-dense snack or add-in. DocMikeEvans. Welcome to Dr.

For example, psychological stress is associated with greater risk for depression, heart disease and infectious diseases. But, until now, it has not been clear exactly how stress influences disease and health. A research team led by Carnegie Mellon University's Sheldon Cohen has found that chronic psychological stress is associated with the body losing its ability to regulate the inflammatory response. Published in the Proceedings of the National Academy of Sciences, the research shows for the first time that the effects of psychological stress on the body's ability to regulate inflammation can promote the development and progression of disease. "Inflammation is partly regulated by the hormone cortisol and when cortisol is not allowed to serve this function, inflammation can get out of control," said Cohen, the Robert E. The CD47-signal regulatory protein alpha (SIRPa) interaction is a therapeutic target for human solid tumors.
Electricity from trees. Plants have long been known as the lungs of the earth, but a new finding has found they may also play a role in electrifying the atmosphere.
Scientists have long-suspected an association between trees and electricity but researchers from Queensland University of Technology (QUT), in Brisbane, Australia, think they may have finally discovered the link. Dr Rohan Jayaratne and Dr Xuan Ling from QUT's International Laboratory for Air Quality and Health (ILAQH), led by Professor Lidia Morawska, ran experiments in six locations around Brisbane, including the Brisbane Forest Park, Daisy Hill and Mt Coot-tha.
They found the positive and negative ion concentrations in the air were twice as high in heavily wooded areas than in open grassy areas, such as parks. Hayflick limit. The Hayflick limit[Note 1] (or Hayflick phenomenon) is the number of times a normal human cell population will divide until cell division stops.
Empirical evidence shows that the telomeres associated with each cell's DNA will get slightly shorter with each new cell division until they shorten to a critical length. The concept of the Hayflick limit was advanced by Leonard Hayflick in 1961, at the Wistar Institute in Philadelphia. Hayflick demonstrated that a population of normal human fetal cells in a cell culture will divide between 40 and 60 times. What's Really Making Us Fat? - Kristin Wartman - Health.
It may not be as simple as calories in, calories out.
New research reveals a far more complex equation for weight gain that places at least some of the blame on organic pollutants. Image: Laborant/Shutterstock Conventional wisdom says that weight gain or loss is based on the energy balance model of "calories in, calories out," which is often reduced to the simple refrain, "eat less, and exercise more.
" But new research reveals a far more complex equation that appears to rest on several other important factors affecting weight gain. Researchers in a relatively new field are looking at the role of industrial chemicals and non-caloric aspects of foods -- called obesogens -- in weight gain. Body clock link to heart disease. Scientists have raised the possibility that cardiovascular disease is linked to disturbances in the body's 24-hour clock.
Working on mice, the Japanese team found a genetic risk factor for a form of high blood pressure is influenced by 24-hour or circadian rhythms. The study appears online in the journal Nature Medicine. Malfunctions in the body clock - which influences much of the body's chemistry - have been linked to many diseases. And lead researcher Professor Hitoshi Okamura said the latest study was in line with data which suggested shift workers, long-distance flight crews and people with sleep disorders have a heightened risk of heart problems. Body clock 'alters' immune system. 17 February 2012Last updated at 01:43 By James Gallagher Health and science reporter, BBC News Will the time affect medicine?
The time of the day could be an important factor in the risk of getting an infection, according to researchers in the US. Heart Surgeon Speaks Out On What Really Causes Heart Disease. We physicians with all our training, knowledge and authority often acquire a rather large ego that tends to make it difficult to admit we are wrong.
So, here it is. I freely admit to being wrong. As a heart surgeon with 25 years experience, having performed over 5,000 open-heart surgeries, today is my day to right the wrong with medical and scientific fact. I trained for many years with other prominent physicians labelled "opinion makers. "
