The researchers speculate that this development could be of great benefit in situations involving ongoing oxidative stress, such as chronic obstructive pulmonary disease and cystic fibrosis. Pre-eclampsia, an abnormal condition during the second half of pregnancy, is characterized by high blood pressure, fluid retention, and the presence of protein in the urine. It can cause maternal and fetal illness and mortality. These researchers found that snoring and partial upper airway obstruction occurred in all women with pre-eclampsia in all stages of sleep. For these women, blood pressure increased steadily throughout the night as they slept.
Houseflies can be a novel biomonitor of atmospheric pollutants.
Because they have an extensive tracheal tubular respiratory system that distributes inhaled substances to all tissues, houseflies can be exposed to levels of ozone and other pollutants over various time periods. Also, researchers found that the houseflies can adapt to varying levels of air pollutants and, as a result, suffer less protein damage to their tissues. Researchers are studying the different mood states related to smoking in men and women. For example, both men and women have positive associations between smoking urge and anger. Men have a smoking urge associated with fatigue, but women do not.
