Filtration: A slow sand filter, pressurized rapid sand filter, or pre-coat filter is the next step in treatment to filter out as many of the blue-green algae cells as possible before the water enters the disinfection system. ï Pressured rapid sand filters are the most common filters used for drinking water ponds.
Reactive urothelial cells and severe, mostly chronic inflammation. -- Urothelial cells, a type of epithelial cell found only in the urinary tract, line the urinary tract and they become reactive (changed) when injured by inflammation.
Urothelial carcinoma, also known as transitional cell carcinoma (TCC), is by far the most common type of bladder cancer. In fact, if you are told you have bladder cancer it is almost certain to be a urothelial carcinoma. These cancers start in the urothelial cells that line the inside of the bladder. Urothelial cells also line other parts of the urinary tract, such as the part of the kidney that connects to the ureter (called the renal pelvis), the ureters, and the urethra. Patients with bladder cancer sometimes have other tumors in these places, so the entire urinary tract needs to be checked for tumors.
