Acute Gastroenteritis which means food poisoning! =D. Agarose Gel Electrophoresis is a method used in biochemistry and molecular biology to separate DNA, RNA, or protein molecules by size. This is achieved by moving negatively charged nucleic acid molecules through an agarose matrix with an electric field (electrophoresis).
When In Doubt, Do CPR. If you're looking at a person you can't wake up and aren't sure if he or she is breathing, he or she probably isn't. If the patient is taking such shallow breaths you can't see the chest rising and falling, it's not enough. If the patient is gasping every few seconds for air, it's not enough. Either way, call 911 and push on the chest. CPR is changing. There's been a lot of research done trying to determine what kind of CPR is better and who should perform it. Simply put: doing something is better than doing nothing.
Normal breath sounds vary according to the diameter of the airways. For example, anteriorly over the trachea, you should hear a loud, high-pitched, hollow sound called a bronchial breath sound. It is abnormal to hear this sound over peripheral lung tissue, that is, away from the trachea and the large bronchi.Over the mainstem bronchi, which are relatively large-diameter airways, you should hear medium-pitched and quieter sounds, called bronchovesicular breath sounds.t is abnormal to hear this sound over peripheral lung tissue, that is, away from the trachea and the large bronchi.
