A new European survey of doctors reveals a glaring blind spot when it comes to watching out for female patients’ heart health. French researchers sent out a questionnaire to 52 general practitioners (GPs). They also obtained access to the medical histories of more than 2,000 of their randomly selected patients. But when they tried to use […]

Cancer Cells Hijack the Body’s Internal Clocks, Study Finds

Posted on Leave a commentPosted in Biomedical Science, Cancer, Cardiovascular, Diagnostics

Cancer patients rare die directly from their tumors. Anyone who’s lost a friend or loved one knows the disease usually wastes away the body. Often, at the end stages, food just doesn’t seem to stick. Now a new study may help explain how and why this happens. Tumor cells disrupt the body’s circadian clocks, interfering […]

Strokes – The 3 types & what to look for

Posted on Leave a commentPosted in Biomedical Science, Cardiovascular, Diagnostics, Emergency Medicine, Medical Advice, Neurology

Two of the most common cardiovascular problems often leading to long term disability or death are heart attacks and strokes. Today’s session will focus on strokes, which according to the world heart federation, is responsible for 15 million cardiovascular cases a year.  What are the different types of strokes? How can you recognize them? What […]

Heart Cancers Are So Extremely Rare It’s As If They Didn’t Exist

Posted on 1 CommentPosted in Cancer, Cardiovascular, Diagnostics, Epidemiology

Food for thought: there are cancers of the brain, blood, lymph nodes, lungs, bone, and every other bodily organ, part, or system imaginable. Why, then, do we never hear about heartcancer — could it be our hearts, long symbolized as the root of loving emotion, are somehow immune to the dreaded disease? Unfortunately, the reason […]

Pancreatic cancer: implantable chemo device may slow, shrink tumors

Posted on Leave a commentPosted in Biomedical Science, Biotechnology, Cancer, Cardiovascular, Medical News, Pharmaceuticals, Pioneering Technology

Researchers have developed a small, implantable device for delivering chemotherapy drugs directly to pancreatic tumors. Tests in mice showed it was up to 12 times more effective than giving the drugs intravenously, which is how most patients receive them. The researchers describe how they developed and tested their innovation in a paper published in the […]

Treating depression may reduce heart disease risk

Posted on 1 CommentPosted in Cardiovascular, Diagnostics, Medical News, Mental Health

Heart disease and depression are both serious and prevalent conditions; mounting evidence infers that they are connected. Depression has been shown to increase the likelihood of developing heart disease later in life. A new study looks in depth at this relationship. An estimated 6.7% of American adults suffered one or more major depressive episodes in […]

Silicon ‘nano-balls’ have wiped out metastatic breast cancer in mice

Human trials could start as early as 2017. Despite all our advances in cancer research, our best strategy of fighting the disease is still brute force, with only a fraction of the drugs administered actually reaching the tumour cells, and most being absorbed into healthy tissue. When cancer spreads, the likelihood of medication reaching it […]

LMU researchers identify new drug target for atherosclerosis

Posted on Leave a commentPosted in Atherosclerosis, Cardiovascular, Medical News

The enzyme Dicer processes RNA transcripts, cutting them into short segments that regulate the synthesis of specific proteins. A Ludwig-Maximilians-Universitaet (LMU) in Munich team has shown that Dicer promotes the development of atherosclerosis, thus identifying a new drug target. The term atherosclerosis refers to a pathological process in which fat-rich deposits in the walls of major […]
