To act as a robust barrier against pathogens while also absorbing needed nutrients, the lining of the intestines must regenerate on a daily basis to remain equal to the task. The intestine's resident ...

Cerebral blood delivery depends on mechanisms such as electrical signaling, which propagates through capillary networks to upstream arterioles to deliver blood, and calcium signaling, which fine-tunes ...

Researchers have developed a human in vitro model that closely mimics the complexities of radiation-induced lung injury (RILI) and radiation dose sensitivity of the human lung. Using a previously ...

Veins in the lungs, or pulmonary veins, play a critical role not only in lung functioning but also in maintaining sufficient ...

Researchers found that endothelial cells lining the veins in lungs contribute to repair of blood vessels after lung injury. Veins in the lungs, or pulmonary veins, play a critical role not only in ...

For example, the hemoglobin denaturation (HD) test and the Ocular Irritection test are in chemico alternatives to the Draize rabbit test. The Draize rabbit test was developed in 1944 to test cosmetic ...
