Inexpensive Arthritis Drug Methotrexate Can Effectively Treat Blood Cancer Sufferers
A simple arthritis drug could be an effective, low cost solution to treat patients with blood cancers such as polycythemia vera (PV) and essential thrombocythemia (ET), a breakthrough study has shown.
Parkinson's Disease May Originate in the Intestines
A theory that Parkinson's disease can arise in the intestinal system and from there migrate to the brain has now gained support from new research.
Popular Drug Reverses Cardiac Remodeling to Treat Heart Failure
Significant improvements in cardiac structure and function, biomarkers of cardiac wall stress and injury, and overall quality of life in the patients, underscores the potent effect of sacubitril/valsartan on cardiac remodeling in heart failure in patients with heart failure and reduced ejection fraction. These trials suggest that sacubitril/valsartan may actually reverse the cardiac remodeling that drives heart failure progression and worsening of clinical outcomes.
Kitchen Sponges Harbor Viruses That Kill Antibiotic-Resistant Bacteria
Researchers have discovered bacteriophages, viruses that infect bacteria, living in their kitchen sponges. As the threat of antibiotic resistance increases, bacteriophages, or phages for short, may prove useful in fighting bacteria that cannot be killed by antibiotics alone.
Healthy, Stress-Busting Fat Found Hidden in Dirt
Thirty years after scientists coined the term 'hygiene hypothesis' to suggest that increased exposure to microorganisms could benefit health, researchers have identified an anti-inflammatory fat in a soil-dwelling bacterium that may be responsible.
Obesity, Diabetes, High Cholesterol More Prevalent Among Irregular Sleepers
A new study has found that not sticking to a regular bedtime and wake up schedule -- and getting different amounts of sleep each night -- can put a person at higher risk for obesity, high cholesterol, hypertension, high blood sugar and other metabolic disorders. In fact, for every hour of variability in time to bed and time asleep, a person may have up to a 27% greater chance of experiencing a metabolic abnormality.
Bid to Beat Superbugs Boosted by Immune Defense Discovery
Scientists have found a molecule produced by the body – called LL-37 – specifically targets infected cells to produce a signal that summons neutrophils while causing infected cells to self-destruct, removing the threat to other healthy cells before the bacteria can grow and spread.
Antibiotics in World's Rivers Exceed 'Safe' Levels in New Global Study
Concentrations of antibiotics found in some of the world's rivers exceed 'safe' levels by up to 300 times, the first ever global study has discovered.
New Protein Discovery Protects Against High-Dose Radiation Damage
Intensive radiotherapy can be toxic in 60 percent of patients with tumors located in the gastrointestinal cavity. The protein URI protected mice against high-dose ionizing radiation-induced gastrointestinal syndrome and enhanced intestinal regeneration and survival in 100 percent of the cases. This finding could be useful to mitigate side effects of other sources of intensive radiation, such as nuclear accidents, nuclear warfare or the exposure to cosmic radiation during space explorations.
Breakthrough in 3D Printing Replacement Organs
Bioengineers bioprint tissues with entangled vascular networks to mimic the body's natural passageways for blood, air, lymph and other vital fluids.
