Crocodilians divert blood through a special vessel called the left aorta to bypass their lungs during digestion. This unique system enables them to secrete gastric acid at an unprecedented rate, facilitating digestion and survival. By shunting CO2-rich blood straight to the stomach, crocodilians maintain optimal digestive conditions.
Localized prostate cancer treatment options face uncertainty due to limited evidence. Gene expression tests for breast cancer hold promise but require further data on benefits and limitations. New HIV treatment guidelines suggest earlier initiation may increase life expectancy for younger patients. Pregnant women should not be screened...
