Unlike later feces, meconium is composed of materials ingested during the time the infant spends in the uterus: intestinal epithelial cells, lanugo, mucus, amniotic fluid, bile, and water. Meconium, unlike later feces, is viscous and sticky like tar – its color usually being a very dark olive green and it is almost odorless. [1]
TAR increases with increasing beam energy because higher energy radiation is more penetrating; TAR decreases with depth because of attenuation; TAR increases with field size due to increased scatter contribution; Measurements for each are taken using an ion chamber for identical source to detector distances and field sizes.

Meconium induces an inflammatory reaction within the lungs as there is an increase of autophagocytic cells and levels of caspase 3 after exposure. After 8 hours of meconium exposure, in rabbit foetuses, the total amount of apoptotic cells is 54%. [15] Therefore, the majority of meconium-induced lung damage may be due to the apoptosis of lung ...
One can produce a tar-like substance from corn stalks by heating them in a microwave oven. This process is known as pyrolysis. Tar is a dark brown or black viscous liquid of hydrocarbons and free carbon, obtained from a wide variety of organic materials through destructive distillation. Tar can be produced from coal, wood, petroleum, or peat. [1]
Health experts recommend reducing a person's intake of ultra-processed foods. A registered dietitian and the CEO of Nourish Science share some helpful ways to spot these foods where you shop.
Thrift Store Shopping and Sustainability. For Gen Z, thrifting is life. The last time shopping for used, vintage clothes and items was this hot was in the 1990’s. And think back to the 80s, when ...
Radiographs in meconium ileus classically demonstrate a bubbly appearance in the right lower quadrant due to a combination of ingested air and meconium. If, on contrast enema, reflux into the dilated distal small bowel loops can be achieved, the study is both diagnostic and therapeutic, as the ionic contrast medium can dissolve the meconium to ...
Mysterious tar balls washed up on several Florida beaches, forcing closures and triggering an investigation by the U.S. Coast Guard. Fort Lauderdale’s shoreline was among the most impacted ...
