Improving the quality of digital pathology imaging

Related video There’s a low-tech problem troubling the high-tech world of digital pathology imaging. The issue: Even as digital pathology makes rapid advances worldwide–with more physicians analyzing tissue images on “smart” computers to diagnose patients–there are no reliable standards for the preparation and digitization of the tissue slides themselves. That means poor quality slides get […]

Scientists get closer to injecting artificial lymph nodes into people to fight disease

Related video In a proof-of-principle study in mice, scientists at Johns Hopkins Medicine report the creation of a specialized gel that acts like a lymph node to successfully activate and multiply cancer-fighting immune system T-cells. The work puts scientists a step closer, they say, to injecting such artificial lymph nodes into people and sparking T-cells […]

Two new epigenetic regulators maintain self-renewal of embryonic stem cells

Related video Embryonic stem cells (ESC) have the ability to self-renew, and, being pluripotent have the potential to create almost any cell type in the body. The embryonic stem cell state is established and maintained by multiple regulatory networks that include epigenetic regulators; the function of these epigenetic regulators though has not been well-defined. An […]

New study finds that previously described differences among endoscopists are not true

Related video Previous research has suggested that specific factors about the doctor performing colonoscopy – for example, a gastroenterologist versus a surgeon, female versus male – were associated with different rates of detection of precancerous polyps. However, a Cleveland Clinic-led research team found that those previously described differences among endoscopists are not true. Adjusting for […]
