Single Dose of Old Drug Boosts Memory, Attention

A drug that for a century has been safely used as a stain and to treat medical disorders could boost activity in brain regions linked to short-term memory and attention, results of a placebo- controlled study demonstrate. Using functional MRI (fMRI), researchers found that a single oral dose of methylene blue increased brain activity in the bilateral insular cortex, as well as the prefrontal cortex and parietal and occipital lobes, compared with placebo. Timothy Q. Duong, PhD, from the University of Texas Health Science Center at San Antonio, pointed out…

Metformin: New Perspectives

We’ve Come So Far, and Yet… Diabetes was transformed from a malignant disease to a chronic disorder just over 90 years ago when insulin became available. Antrectomy with vagotomy for ulcer—which I scrubbed in on as a surgical rotation student—has gone the way of the history book due to H2 blockers and proton pump inhibitors. These and other medicines have literally transformed the management of the diseases for which they are used. A typical patient with diabetes who has been referred to a specialist can expect to be prescribed two…

Vitamin B12 May Slow Brain Aging

Individuals with increased levels of circulating homocysteine have faster rates of brain changes associated with aging than other people, whereas higher levels of vitamin B12 are associated with slower rates of brain aging, new research suggests. Babak Hooshmand, MD, PhD, Center for Alzheimer Research–Aging Research Center, Karolinska Institutet, Stockholm, Sweden, and colleagues found that total brain volume losses were lower in individuals with higher baseline vitamin B12 levels, whereas the opposite was true of those with increased homocysteine levels. “Vitamin B12 and tHcy [total homocysteine] might be independent predictors of…

Soil Is the Solution

It’s easy to take soil for granted. That is, until you lose it. The dirt beneath your feet is arguably one of the most under-appreciated assets on the planet. Without it, life would largely cease to exist while, when at its prime, this “black gold” gives life.

It contains microorganisms that thrive on chemicals released from the plant’s roots. These chemicals, known…
