And what does a truly digital age imply for the ethics and social structures of ecosystem citizens? Age of Design. Ecosystems are about people, their activities and the fundamental human need to share and build emotional relationships.
Biochemical reactions in your body rapidly convert ammonia into less harmful molecules under normal conditions. Liver disease can cause ammonia levels to build up in your body. Your brain is normally protected from the low levels of ammonia in your body by the blood-brain barrier. Liver disfunction can cause ammonia levels to build up in your brain causing permanent brain damage, a condition known as hepatic encephalopathy.
Normal concentrations of ammonia do not rule out hepatic encephalopathy. Other wastes can contribute to changes in mental function and consciousness, and brain levels of ammonia may be much higher than blood levels. This can make correlation of a person's symptoms to ammonia blood levels difficult. A decreased level of ammonia may be seen with some types of hypertension, such as essential (high blood pressure of unknown cause) and malignant (very high blood pressure that occurs suddenly and quickly). ^ Back to top.
