Health Research: Accelerated brain aging in type 1 diabetes ♦ The dark side of cannabis: Panic attacks, nausea ♦ New leads into nerve regeneration

Accelerated brain aging in type 1 diabetes related to cognitive complications The brains of people with type 1 diabetes show signs of accelerated aging that correlate with slower information processing, according to research. The findings indicate that clinicians should consider screening middle-aged patients with type 1 diabetes for cognitive difficulties. If progressive, these changes could influence their ability to manage their diabetes.
Although the use of cannabis as a medical drug is currently booming, we should not forget that leisure time consumption -- for example, smoking weed -- can cause acute and chronic harms. These include panic attacks, impaired coordination of movement, and nausea.
Proteomics provides new leads into nerve regeneration Using proteomics techniques to study injured optic nerves, researchers have identified previously unrecognized proteins and pathways involved in nerve regeneration. Adding back one of these proteins -- the oncogene c-myc -- they achieved unprecedented optic nerve regeneration in mice when combined with two other known strategies.
Profiling approach to enable right lung cancer treatment match A new way to genetically profile lung cancer samples has been developed by researchers, potentially allowing doctors to more easily identify the most appropriate treatment for patients.
Breast cancer vaccines may work better with silicon microparticles The effectiveness of cancer vaccines could be dramatically boosted by first loading the cancer antigens into silicon microparticles, report scientists. Model studies showed that microparticles loaded with an antigen, HER2, not only protected the antigen from premature destruction, but also stimulated the immune system to recognize and relentlessly attack cancer cells overexpressing the HER2 antigen.
