Mutations in the VWF gene cause von Willebrand disease. The VWF gene provides instructions for making a blood clotting protein called von Willebrand factor, which is essential for the formation of blood clots.ype 3 is the most severe and rarest form of the condition. The four subtypes of type 2 von Willebrand disease are intermediate in severity. Another form of the disorder, acquired von Willebrand syndrome, is not caused by inherited gene mutations.
A vaporizer or vaporiser (a âvapeâ) is a device used to vaporize the active ingredients of plant material, commonly cannabis, tobacco, or other herbs or blends for the purpose of inhalation. However, they can also be filled with a mixture of propylene glycol, glycerin, and nicotine. (e.g. tobacco-free nicotine).
Vaping is an alternative to smoking. Itâs like smoking minus several of the adverse effects of the latter: no bad smell and bad breath, no cigarette burns, no more dirty ashtrays, less likelihood of getting cancer and other smoking-affiliated illnesses â you get the drift. In short, vaping is the name given to the use of a vaporizer. The process involves applying heat to a liquid which generates vapor. The user, called a vaper (smoker in traditional cigarette circles) gets their nicotine hit through inhaling the almost odorless vapor (smoking equivalent of âsmokeâ).
