A research team from Washington State University has shown for the first time that nicotine residue can be extracted from plaque, also known as "dental calculus," on the teeth of ancient tobacco users. The research provides a new method that could help trace the ancient use of tobacco and other intoxicating plants further back into prehistory. The study findings were published in Journal of Archaeological Science Reports.

Researchers at the National Institutes of Health have cured mice with Chuvash polycythemia, a life-threatening disorder that involves the overproduction of red blood cells. They treated the mice using Tempol, an experimental drug being studied for the treatment of diabetes, cancer and other diseases. The findings offer hope that Tempol or a similar drug may treat polycythemias that affect humans, such as mountain sickness—a serious blood complication experienced in low-oxygen, high-altitude settings. The study appears in The Journal of Clinical Investigation.
Primary care physicians spent more time working in the electronic health record (EHR) than they spent in face-to-face time with patients in clinic visits, according to a new study published in the recent issue of Family Medicine.
Fifty-five patients representing 17 cancer types tested positive for TRK fusion and were treated with larotrectinib. The overall response rate was 75%.
Critically ill patients who experience long periods of hypoxic, septic or sedative-associated delirium, or a combination of the three, during an intensive care unit (ICU) stay are more likely to have long-term cognitive impairment one year after discharge from the hospital, according to a new study from the University of Pittsburgh and Vanderbilt University. This is the first study to show more than half of patients with acute respiratory failure or shock, or both, develop multiple sub-categories of delirium with lasting effects.
According to a new study, a special receptor on cells that line the sinuses, throat, and lungs evolved to protect mammals from developing a range of allergies and asthma.
Researchers at St George's, University of London, say their new study shows the classic symptoms associated with bacterial meningitis are uncommon in young infants less than three months of age – the group at highest risk of the disease.
In this study, researchers found the ongoing clinical challenge of treating moderate-to-severe Graves' orbitopathy show some potential benefits from the addition of mycophenolate mofetil to the standard of care, methylprednisolone, no benefit from the addition of radiotherapy to oral steroids. The study has published in The Lancet Diabetes & Endocrinology.
According to a new study, researchers examined the efficacy of moisturizer containing 4-t-butylcyclohexanol, which acts as a sensitivity regulator, and licochalcone A, an anti-inflammatory agentfrom the licorice plant Glycyrrhiza inflata, with that of 0.02% triamcinolone ace-tonide (TA) for the treatment of facial dermatitis. The study has published in the Journal of Cosmetic Dermatology.
Reactive oxygen species (ROS) are the unstable molecule containing oxygen. ROS plays an essential role in cell signaling and homeostasis. But, at times of environmental stress ROS levels increases resulting significant damage to cell structures
According to new research, they have demonstrated by targeting vaccine and other interventions to those near people with cholera could be an effective way to control cholera outbreaks, which can have devastating effects after disasters and in different emergency settings. The study was published in PLOS Medicine.
A new study has demonstrated that premature birth has a significant and, at the same time, a very selective effect on the functional networks of a child's brain. The results can primarily be seen in the frontal lobe, which is significant for cognitive functions. Premature birth is globally the most critical risk factor for lifetime disorders and defects in neurocognitive functions.
