Exercise impacts on gut bacteria, causing both brain activity and metabolic activity. A new study, published in the journal Immunology and Cell Biology, has specified the overall impact of the human gut bacteria on health over the course of a lifetime.
A new study, published by the Sahlgrenska Academy in the journal Cell Metabolism, has revealed that a dietary treatment works for some individuals and it depends on interactions between the gut microbiota and the diet.
Dr. Ruth Edge from The University of Manchester, together with her colleagues Professor George Truscott from Keele University and Professors Fritz Boehm & Christian Witt from Berlin, undertook a study of lycopene (one of the carotenoids – plant pigments found in many fruits and vegetables) and its effectiveness at protecting against radiation at the University of Manchester’s Dalton Cumbrian Facility, part of the Dalton Nuclear Institute.
“We have shown that lycopene can protect human cells efficiently against gamma radiation at low, but not high oxygen concentrations, and we hope that this effect may allow for improvements in radiation cancer therapy if the oxygen concentration can be increased in solid tumours compared to the healthy surrounding tissue”, said Dr. Ruth Edge, Experimental Officer and Laboratory Manager, Dalton Cumbrian Facility.
Radiation therapy is used to treat a wide range of tumors, but until now, its side effects have constrained its effectiveness. Recently, there has been interest in the possible role of dietary carotenoids in limiting these effects. In addition, interest has grown in identifying dietary counter-measures against nuclear accidents.
The results of the study, published in FEBS Letters, have shown that lycopene is an effective carotenoid at offering protection from the damaging effects of gamma radiation, and that dietary intervention could be useful in efforts to defend people from these effects. A major finding of the study is that such protective effects are reduced as the oxygen concentration is increased.
Gut bacteria have been associated with a number of immune diseases and treatment of diverse medical conditions. A new study presented at the National Cancer Research Institute’s (NCRI) Cancer conference in Liverpool has highlighted the role of gut bacteria with cancer immuno-therapy treatment.

A study analyzing populations across 187 countries found that high sodium intake, of more than 2,000 mg per day, caused 1.6 million cardiovascular-related deaths per year. Continue reading “Sodium consumption causes 1.6 million deaths per year.”
A study published in the Journal Clinical Endocrinology & Metabolism has revealed that people who have metabolic syndrome have a heightened risk of dying from heart disease than those without the condition. Another study has revealed the racial differentiation associated with cardiovascular disease as metabolic syndrome may increase the risk more in black women than in white women.

Breast cancer affected 1.7 million women globally in 2012. A new study published in the journal Nature Genetics has revealed a new RECQL mutation strongly linked to the development of breast cancer.

According to a study published in the American College of Cardiology running only a few minutes a day even at a slow speed significantly reduces the risk of death from cardiovascular disease. Continue reading “Running decreases mortality rate.”
