Research shows that repeated administrations of radionuclide therapy with 188Re-HEDP improve overall survival rates, reducing pain in prostate cancer patients with hormone-refractory bone metastases. The study found significant increases in post-treatment survival for patients receiving two or three therapies.
Researchers found that inhibiting Notch signalling converts triple-negative breast cancer cells into hormone-receptor positive cells, making them dependent on estrogen. This technique has potential for combination therapy, where a Notch inhibitor is used to make all cancer cells hormone-sensitive.
A clinical trial of resveratrol supplements has shown significant metabolic shifts in obese men, comparable to calorie restriction. The study found improved measures of metabolism, lower blood sugar levels, and a drop in blood pressure, with no apparent side effects.
The Thermal Infrared Sensor (TIRS) has successfully completed its first round of thermal vacuum testing at NASA's Goddard Space Flight Center. The test evaluated the fully-assembled instrument at its normal operating temperature, achieving results that surpass expectations in some areas.
