A pre-clinical study of ANAVEX 2-73 found that it prevents mitochondrial dysfunction and blocks resulting oxidative stress and apoptosis (cell death) in a nontransgenic mouse model of Alzheimer's disease (AD).

Mitochondrial damages have been consistently reported as an early cause of Alzheimer's disease and appear before amyloid-beta plaques and memory decline in Alzheimer's patients and transgenic mice. If so, by preserving mitochondrial functionality and reducing other key Alzheimer's disease hallmarks, it has the potential to prevent, stop, slow or reverse the disease, in addition to treating its symptoms.
Competition between doctors' offices, urgent care centers and retail medical clinics that cater to wealthy elites often leads to an increase in the number of antibiotic prescriptions written per person, finds a new analysis.

The number of physicians per capita and the number of clinics are significant drivers of antibiotic prescription rate, they found, with the highest per capita rates of antibiotic prescriptions found in the southeastern U.S. and along the West and East coasts. The team's comparative analysis of data for the years 2000 and 2010 were collected from the U.S. Census Bureau and the IMS Health Xponent database, which tracks prescriptions dispensed at the ZIP code level. Notably high rates were found in Manhattan, southern Miami and Encino.
Statins, cholesterol-lowering drugs prescribed to prevent heart attacks for the last two decades, are not as effective nor as safe as claimed, according to a review by Dr. David M. Diamond, a psychologist at the University of South Florida, and Dr. Uffe Ravnskov, an independent researcher.

According to Diamond and Ravnskov, statins produce a dramatic reduction in cholesterol levels, but they have "failed to substantially improve cardiovascular outcomes." They further state that the many studies touting the efficacy of statins have not accounted for the adverse side effects of the drugs, but supporters of statins have used what the authors refer to as "statistical deception" to make inflated claims about their effectiveness. 
Picture this: For the past two weeks you have felt continuously dejected. You have lost interest in what normally makes you happy. Perhaps you’ve slept poorly or lost your appetite. There is a risk that you have one of the most common maladies in the world: Depression.

You decide to see a doctor. She considers different treatments and finally she gives you a prescription for a small box of antidepressants. Whether they will help you is unclear. Some patients report an effect after two or three weeks, others don’t notice any change at all. Some even get even more depressed.

More depressed? If it is actually a healthy person who doesn't have clinical depression, it's certainly possible. 
Diabetes is a significant risk factor for developing eye diseases and the most common diabetic eye disease and a leading cause of blindness is diabetic retinopathy, which is caused by elevated blood sugar levels damaging the blood vessels of the retina and affects approximately 7.7 million Americans.

About 750,000 Americans with diabetic retinopathy have diabetic macular edema (DME) in which fluid leaks into the macula, the area of the retina used when looking straight ahead. The fluid causes the macula to swell, blurring vision.
Human papillomaviruses (HPV) infect epithelial cells in the skin and mucosal tissue and can cause tumor-like growth. Some of these viruses also develop malignant tumors, especially cervical cancer in women, which kills around 4,000 women each year.
A nicotine metabolite once thought to be inactive, cotinine, instead supports learning and memory, by amplifying the action of a primary chemical messenger involved in both, finds a new study.

The new findings indicate cotinine makes brain receptors more sensitive to lower levels of the messenger acetylcholine, which are typical in Alzheimer's, and may boost effectiveness, at least for a time, of existing therapies for Alzheimer's and possibly other memory and psychiatric disorders.
A 10-year retrospective study of 383 children is the first to examine the prevalence of positive drug screens in pediatric patients undergoing  multiple sleep latency test (MSLT) for narcolepsy.

The results in Journal of Clinical Sleep Medicine showed that 43 percent of children with urine drug screens positive for marijuana actually had test results consistent with narcolepsy or abnormal REM sleep patterns. No child younger than 13 years of age had a positive urine drug screen. The data showed that males were more likely to have a positive urine drug screen and MSLT findings consistent with narcolepsy.  
Virginia state legislators just passed a bill that makes cannabidiol and delta9-tetrahydrocannabinol carboxylic acid (THC-acid or THCA) legal for the treatment of intractable epilepsy. You can read the bill here.

The problem is that while there is some evidence that cannabidiol might help treat intractable epilepsy, for which GW pharmaceuticals is testing Epidolex, there is little evidence for THCA.
