Amorphous calcium carbonate enhances osteogenic differentiation and myotube formation of human bone marrow derived mesenchymal stem cells and primary skeletal muscle cells under microgravity conditions.

Astronauts are exposed to severely stressful physiological conditions due to microgravity and increased space radiation. Space environment affects every organ and cell in the body and the significant adverse effects of long-term weightlessness include muscle atrophy and deterioration of the skeleton (spaceflight osteopenia). Amorphous Calcium Carbonate (ACC) emerges as a promising candidate for prevention of these effects, owing to its unique physicochemical properties and its potential to address the intricately linked nature of bone-muscle crosstalk.

Lower Extremity Amputee Outcomes with Reference to Co-morbidities.

Background: Lower extremity amputation related to diabetes is a serious outcome, which can have devastating effects on the patient and family. The epidemiology of amputations has recently been used as a possible measure of the adequacy of medical prevention and treatment of diabetes and diabetic foot complications.

Objectives: To report on patients undergoing amputations at one medical center in Israel, their co-morbidities, and the outcomes.
