Cancer Research: Virus in cattle linked to human breast cancer ♦ Genetic mechanism for cancer progression discovered ♦ Keeping one step ahead of cancer cells

Genetic mechanism for cancer progression discovered Genetics researchers have identified a novel long non-coding RNA, dubbed DACOR1, that has the potential to stymie the growth of tumor cells in the second-most deadly form of cancer in the US -- colorectal cancer.

Drug resistance in cancer patients linked to oxygen-bearing molecules in body Increased levels of certain chemically reactive, oxygen-containing molecules in the body can cause patients to become resistant to cancer drugs such as chemotherapy.

Mediterranean diet plus olive oil associated with reduced breast cancer risk Eating a Mediterranean diet supplemented with extra virgin olive oil was associated with a relatively lower risk of breast cancer in a study of women in Spain.

Virus in cattle linked to human breast cancer For the first time, researchers have established a link between infection with the bovine leukemia virus and human breast cancer. Researchers analyzed breast tissue from 239 women, comparing samples from women who had breast cancer with women who had no history of the disease for the presence of bovine leukemia virus (BLV). They found that 59 percent of breast cancer samples had evidence of exposure to BLV, as determined by the presence of viral DNA.

Keeping one step ahead of cancer cells BRD4 inhibitors are among the most promising new agents in cancer therapy that are currently evaluated in clinical trials. In a new study, a team of researchers reveals how leukemia cells can evade the deadly effects of BRD4 inhibition. Understanding this adaptation process could aid the development of sequential therapies to outsmart resistant leukemias.

Nutritional Research: Eating a Mediterranean diet could cut womb cancer risk ♦ Increasing dietary fiber reduces risk of developing diabetes ♦ Memories influence choice of food

Memories influence choice of food The stronger our memory is of a certain food, the more likely we are to choose it -- even if it is the more unattractive option. Psychologists conducted a study on how memory influences our choices by offering various foods and using scans to track brain activity. The researchers were able to show that the influence of memory is mediated by increasing communication between the relevant brain areas.

Study questions beneficial effects of a Nordic diet on cardiovascular events Although individual components of a healthy so-called Nordic diet previously have been linked to beneficial effects on cardiovascular health, as well as to other health effects, there is no evidence of an association with cardiovascular events in a general population

Eating a Mediterranean diet could cut womb cancer risk Women who eat a Mediterranean diet could cut their risk of womb cancer by more than half (57 per cent), according to a new study.

Increasing dietary fiber reduces risk of developing diabetes Consuming greater quantities of dietary fiber reduces the risk of developing type 2 diabetes, Over 360 million people worldwide are estimated to be affected by diabetes, and this number is projected to increase to more than 550 million by 2030, with serious consequences for the health and economy of both developed and developing countries.

Heart Health:Mediterranean diet cuts heart disease risk ♦ anger can trigger a heart attack! ♦ Eating Peanuts associated with decreased cardiovascular diseases ♦ Plus more

Mediterranean diet cuts heart disease risk by nearly half Adults who closely followed the Mediterranean diet were 47 percent less likely to develop heart disease over a 10-year period Continue Reading

Keep calm, anger can trigger a heart attack!  The risk of a heart attack is 8.5 times higher in the two hours following a burst of intense anger, researchers have found after investigating the link between acute emotional triggers and high risk of severe cardiac episodes Continue Reading

Homeless people with mental illness have higher 30-year risk of serious cardiovascular disease, research finds  Homeless people with mental disease have a greater than double risk of developing serious or fatal cardiovascular disease over 30 years than people of the same age and gender with no risk factors for the disease, Continue Reading

Peanut consumption associated with decreased total mortality from cardiovascular diseases  Researchers have examined the association of nut and peanut consumption with mortality among low-income and racially diverse populations and found that intake of peanuts was associated with fewer deaths from heart disease.Continue Reading

Excess sitting linked to coronary artery calcification, an early indicator of heart problems Sitting for many hours per day is associated with increased coronary artery calcification, a marker of subclinical heart disease that can increase the risk of a heart attack, according to research. Coronary artery disease is the leading cause of death in the United States.Continue Reading

12/7/14 Health News: New approach to treating asthma ♦ Mediterranean diet linked to longer life ♦ Fracking chemical can harm reproduction ♦ Compound eliminates malaria parasite

Novel approach to treating asthma: Neutralize the trigger

Current asthma treatments can alleviate wheezing, coughing and other symptoms felt by millions of Americans every year, but they don't get to the root cause of the condition. Now, for the first time, scientists are reporting a new approach to defeating asthma by targeting the trigger -- the allergen -- before it can spark an attack Continue Reading

Mediterranean diet linked to longer life

Eating a Mediterranean diet might help extend your lifespan, suggests a study. The diet appears to be associated with longer telomere length -- an established marker of slower aging Continue Reading

Chemicals released during natural gas extraction may harm reproduction, development

Unconventional oil and gas operations combine directional drilling and hydraulic fracturing to release natural gas from rock. Discussions have centered on potential air and water pollution from chemicals and how they affect the more than 15 million Americans living within one mile of UOG operations. Now, a researcher has conducted the largest review of research centered on fracking byproducts and their effects on human reproductive and developmental health Continue Reading

Promising compound rapidly eliminates malaria parasite

A promising anti-malarial compound tricks the immune system to rapidly destroy red blood cells infected with the malaria parasite but leave healthy cells unharmed, an international group of researchers has found. Planning has begun for safety trials of the compound in healthy adults. Continue Reading

1/23/14 Health News: Salmonella Biofilms Resists Disinfectants - Concussions Diagnosed on Sports Field - Toxin Kills of HIV- Mediterranean Diet Cuts Type 2 Diabetes

SALMONELLA BIOFILMS EXTREMELY RESISTANT TO DISINFECTANTS

Researchers have discovered that common disinfectants face an uphill battle killing Salmonella once it has had the time to form a biofilm – a community of cells that attach to each other and a surface, increasing the density of bacterial growth and providing support from harsh environments. Researchers at the National University of Ireland, Galway,... Continue Reading

A New Blood Test to Diagnose Concussions on the Sports Field

A protein could signal the first signs of brain changes due to a concussion.

With a finger-stick and a drop of blood, researchers from the University of Rochester say it may be possible to tell whether a player experienced a concussion. Levels of the brain protein S100B start to rise with intense exertion, but also after a major impact such as a blow to the head. So the scientists investigated whether it would be possible to distinguish the two circumstances in hopes of finding a way to detect the first signs of traumatic brain injury. Based on their findings, the researchers concluded that a rise in S100B of more than 45% is nearly equivalent to a concussion diagnosis, and easily distinguishable from physical exertion..continue reading

Toxin Shows Promise in Killing Off Lurking HIV

An antibody and toxin mix has successfully detected and killed HIV-infected cells lurking in the organs and bone marrow of mice that were altered to have a human immune system. The results, reported offer conceptual proof that a reservoir of HIV-infected cells in organs can sought out and destroyed, a scenario that would potentially end the stalemate between the virus and antiretroviral drug therapies. The altered mice, developed about eight years ago, can be infected by the human immunodeficiency virus in an identical manner to humans; they exhibit the same viremia and respond the same way to current antiretroviral drug therapy, but do not come down with AIDS, according to the study.Continue Reading
