ASSESSMENT OF SCATTERED AND LEAKAGE RADIATION FROM ULTRA-PORTABLE X-RAY SYSTEMS IN CHEST IMAGING: AN INDEPENDENT STUDY.

Assessment of scattered and leakage radiation from ultra-portable X-ray systems in chest imaging: An independent study.

Ultraportable (UP) X-ray devices are ideal to use in community-based settings, particularly for chest X-ray (CXR) screening of tuberculosis (TB).Unfortunately, there is insufficient guidance on the radiation safety of these devices.This study aims to determine the radiation dose by UP X-ray devices to both the public and radiographers compared to i

Migration of culture-expanded human mesenchymal stem cells through bone marrow endothelium is regulated by matrix metalloproteinase-2 and tissue inhibitor of metalloproteinase-3

Background and Objectives Mesenchymal stem cells (MSC) are adult stem cells that can be expanded many fold in vitro and have the therapeutic potential to edgewater shoes restore the bone marrow microenvironment and support hematopoietic recovery after myeloablative conditioning for hematopoietic stem cell transplantation.Successful homing to the ta
