Researchers discovered that HIV protease inhibitors can prevent photoreceptor apoptosis in mouse models of retinal detachment, reducing the cause of vision loss. CD133 expression was found not to be restricted to stem cells, and both CD133+ and CD133– metastatic colon cancer cells can initiate tumors.
An experimental drug, OSU-HDAC42, has blocked prostate cancer progression in mice with an aggressive form of the disease. The agent reactivates genes that normally protect against cancer, shifting tumor progression to a more benign direction.
The home telehealth and remote patient monitoring market is projected to grow at a rate of 70% over the next three to five years, driven by increasing demand for convenient and accessible healthcare services.
