His Owner Thought Something Was Wrong With Him. Little Did She Know He Was About to Save Her Life. By: Oliver Darcy Maureen Burns’ dog Max was usually full of life. That’s why when the 9-year-old collie cross started behaving strangely, she assumed the worst. coque iphone 7 “I thought at the time, Max was fading. He was nine-and-a-half and I was preparing myself for losing him,” she told BBC Earth. Little did Burns know, Max was perfectly healthy. She, however, wasn’t and Max knew why. “[Max] would come up and touch my breast with his nose, and back off so desperately unhappy…” “[He] wouldn’t come with me, wouldn’t sit by me, wouldn’t sit on my lap,” Burns explained. coque iphone xr ”The odd signs were when he would come up and touch my breast with his nose, and back off so desperately unhappy with such a sad look in his eyes.” Burns had a lump in her breast, but because her last mammogram had come back clear, she didn’t think anything of it. That’s until she connected the lump with Max’s behavior. coque iphone xs Burns scheduled a follow-up mammogram and scan. Both came back negative. coque iphone Still worried, she underwent a surgical biopsy. coque iphone 2019 Cancer was detected. According to BBC Earth, dogs can smell chemicals from cancerous tumors. coque iphone 8 In fact, as TheBlaze previously reported, research continues to confirm the accuracy with which dogs can smell cancer. Burns said that when she went home after her tumor had been removed, things were quite different with Max. “He put his nose across my breast to check where the operation had been and was wagging his tail and his eyes were happy,” she told BBC Earth.

Video: Epigenetics – Nature vs. Nurture in Cancer Research

Posted on July 12, 2014October 6, 2019 by admin@wholeuni

Once nurture seemed clearly distinct from nature. Now it appears that our diets and lifestyles can change the expression of our genes. coque iphone 6 How? By influencing a network of chemical switches within our cells collectively known as the epigenome. This new understanding may lead us to potent new medical therapies. vente de coque iphone Epigenetic cancer therapy, for one, already seems to be yielding promising results.

http://www.pbs.org/wgbh/nova/body/epigenetics.html In biology, and specifically genetics, epigenetics is the study of heritable changes in gene activity that are not caused by changes in the DNA sequence; it also can be used to describe the study of stable, long-term alterations in the transcriptional potential of a cell that are not necessarily heritable. Unlike simple genetics based on changes to the DNA sequence (the genotype), the changes in gene expression or cellular phenotype of epigenetics have other causes, thus use of the term epi- (Greek: επί- over, outside of, around) -genetics. The term also refers to the changes themselves: functionally relevant changes to the genome that do not involve a change in the nucleotide sequence. coqueiphone Examples of mechanisms that produce such changes are DNA methylation and histone modification, each of which alters how genes are expressed without altering the underlying DNA sequence. coque iphone Gene expression can be controlled through the action of repressor proteins that attach to silencer regions of the DNA. coque iphone These epigenetic changes may last through cell divisions for the duration of the cell’s life, and may also last for multiple generations even though they do not involve changes in the underlying DNA sequence of the organism; instead, non-genetic factors cause the organism’s genes to behave (or “express themselves”) differently. (There are objections to the use of the term epigenetic to describe chemical modification of histone, since it remains unclear whether or not histone modifications are heritable.) One example of an epigenetic change in eukaryotic biology is the process of cellular differentiation. During morphogenesis, totipotent stem cells become the various pluripotent cell lines of the embryo, which in turn become fully differentiated cells. In other words, as a single fertilized egg cell – the zygote – continues to divide, the resulting daughter cells change into all the different cell types in an organism, including neurons, muscle cells, epithelium, endothelium of blood vessels, etc., by activating some genes while inhibiting the expression of others. In 2011, it was demonstrated that the methylation of mRNA plays a critical role in human energy homeostasis. The obesity-associated FTO gene is shown to be able to demethylate N6-methyladenosine in RNA.

The Mind-Body Aspects Of Yoga & Breast Cancer

Posted on March 6, 2014October 6, 2019 by admin@wholeuni

The mind-body aspects of yoga specifically could carry benefits for women undergoing breast cancer treatment, according to a small new study.

The research, published in the Journal of Clinical Oncology, shows that women undergoing radiation therapy for breast cancer who were enrolled in a yoga intervention (that included meditation, relaxation and breathing techniques) experienced improved stress hormone regulation, decreased fatigue and improved general health.

“Combining mind and body practices that are part of yoga clearly have tremendous potential to help patients manage the psychosocial and physical difficulties associated with treatment and life after cancer, beyond the benefits of simple stretching,” study researcher Lorenzo Cohen, Ph.D., director of the Integrative Medicine Program at the University of Texas MD Anderson Cancer Center, said in a statement.

The study included 191 women with breast cancer of varying stages, who were randomly assigned to one of three groups as they underwent their radiation treatment for six weeks. One group did simple stretching, the second group did yoga, and the third group did no yoga or stretching. The yoga and stretching groups did their assigned activity for one hour, three times a week.

The participants self-reported their fatigue and depression levels throughout the intervention, and researchers also collected saliva samples and administered echocardiogram tests at the beginning of the study, at the end of the radiation treatment, and then one, three and six months after the radiation treatment had ended.

They found that overall, the participants who were assigned to the yoga group experienced the greatest gains in all measurements of health. Specifically, the yoga group had the greatest decreases in cortisol levels throughout the day. And after radiation treatment, the yoga and stretching groups experienced decreases in fatigue, compared with the control group. Months after the radiation treatment, the yoga group self-reported higher general health, and were also more likely than the other two groups to say that they found some kind of meaning of life from their cancer experience.

Previous research has indicated that yoga could decrease inflammation and fatigue among breast cancer survivors. One study showing this effect, published in the same journal as the new study, posited that the beneficial effects could come from yoga’s ability to improve sleep.
