A recent paper published in Age & Ageing, the scientific journal of the British Geriatrics Society, finds that current smoking in older people increases the risk of developing frailty, though former smokers did not appear to be at higher risk.
Writing today in the journal Cancer Research, James DeGregori, Ph.D., deputy director of the University of Colorado Cancer Center offers evidence that it is forces of evolution driven by natural selection acting in the ecosystem of the body that, in the presence of tissue damage, allow cells with dangerous mutations to thrive.
CRG scientists identify important processes that create mutations that cause cancer by studying the genomes of more than 1,000 tumors. Many mutations in human cancers are caused by mistakes made by a repair mechanism or 'DNA spellchecker' rather than the actual damage to DNA caused by the environment. Sunlight and alcohol consumption increase the rate at which this happens, resulting in more mutations in the most important parts of our genomes.
University of California San Diego School of Medicine and Moores Cancer Center researchers performed a population-level analysis of national surveys conducted from 2001 to 2015 and found that in the United States the smoking cessation rate increased for the first time in 15 years. The study suggests e-cigarettes helped users of the electronic devices to quit smoking traditional cigarettes.
A new collaborative Dartmouth study finds strong and consistent evidence of greater risk between initial e-cigarette use and subsequent cigarette smoking initiation, regardless of how initiation was defined and net other factors that predict cigarette smoking.
Researchers compared the thickness of brain cortex in patients with brain tumors before and after radiation therapy was applied and found significant dose-dependent changes in the structural properties of cortical neural networks, at both the local and global level.
Anticancer agents targeting microtubule from marine sources hold great potential in the field of cancer therapeutics and are gradually advancing in the clinical setup.
Researchers from the University of Luxembourg, in cooperation with the University of Strasbourg, have developed a computational method that could be used to guide surgeons during brain surgery.
Tobacco-specific nitrosamines (TSNAs) are potent carcinogens formed predominantly during the cigarette manufacturing process. Despite initial success lowering TSNA levels in cigarettes sold in Canada, following subsidies by the Ontario government to manufacturers in 2000, a study published today in the journal Nicotine & Tobacco Research has found that the decrease in TSNAs have not been sustained.
An IDIBELL research team manages to characterize the complete epigenomes of the most frequent tumors, including those of colon, lung and breast cancer. The study represents a big step in the study of origin and progression of these tumors.
