Potential drug therapy for diabetic retinopathy under study

Scientists are exploring the therapeutic potential of (+)- pentazocine in treating diabetic retinopathy. The study aims to determine if the drug can block or promote sigma receptor action and improve retinal health in patients. Researchers also want to know if the drug is effective when given later in the disease process.

Vacuum arcs spark new interest

Scientists model vacuum breakdown to understand its implications for applications, including particle accelerators and fusion reactors. A new model reveals that the breakdown arc is triggered by an electric field tearing apart the metal surface, leading to extremely damaging effects.

Mild painkillers in pregnancy are associated with an increased risk of male reproductive problems

Research found a seven-fold increased risk of undescended testicles in sons born to women taking multiple painkillers during pregnancy. The study suggests that exposure to certain chemicals, including mild analgesics, can disrupt testosterone production and lead to poor semen quality and testicular cancer.

Soy may stop prostate cancer spread

Researchers at Northwestern University have found that a soy-based drug can prevent the movement of prostate cancer cells from the prostate to the rest of the body. The experimental treatment, genistein, has shown beneficial effects on human subjects with localized prostate cancer in a recent phase II study.

Do not abandon new cigarette warning labels

Health Canada's decision to cancel plans for new cigarette warning labels may result in increased smoking rates and a surge in smoking-related illnesses and deaths. Warning labels are an effective communication strategy that deter smokers and non-smokers alike, with international guidelines recommending large pictorial warnings.

Greater food insecurity from recession poses increased risk to low income individuals with diabetes

A new study found that food-insecure adults with diabetes have higher body mass indexes and greater financial constraints on food choices. However, after receiving nutrition education via telemedicine, both groups reported improved diet adherence and similar lab values associated with diabetes care.

Louisiana State University Health Sciences Center research shows fish oil component given up to 5 hours after stroke limits brain damage

A study by LSU Health Sciences Center researchers found that Docosahexaenoic acid (DHA), a fish oil component, can protect brain tissue and promote recovery in acute ischemic stroke even when treatment is delayed. DHA treatment reduced swelling and facilitated neurobehavioral recovery.
