Here Are the Safest and Most Effective Sunscreens
Summer means more time in the sun, which can be good for the bones—all that vitamin D—but bad for the skin. In its annual report on the sunscreens with the least toxic ingredients that are also effective, the Environmental Working Group (EWG) found more than 250 products that measure up. All are free of two ingredients the Food and Drug Administration (FDA) has deemed are not generally safe and effective—PABA and trolamine salicylate—based on research showing these chemicals can contribute to immune system changes and other adverse health effects. The FDA has determined that two other active ingredi...

Doctors and public health officials have long recommended that people use sunscreen to protect against the sun’s ultraviolet rays. But how safe are the sunscreens that so many people now use regularly?

Discussion The liver is one of the largest organs in the body, weighing just over 3 pounds in an adult. It is found in the upper right abdomen, under the right dome of the diaphragm. Grossly, it has asymmetric lobes with the right being larger than the left. The lobes are separated by a fibrous connective tissue band that also anchors the liver in the abdominal cavity. The gallbladder is located on the inferior surface of the liver and stores bile, which is then released into the duodenum. Microscopically, the liver cells are arranged in lobules with canals carrying blood vessels and bile ducts. At any moment about 10-13% ...
