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.
Physical Exam. Your doctor will listen to your breathing with a stethoscope to find out whether your lungs are making any abnormal sounds. If you have pleurisy, the inflamed layers of the pleura make a rough, scratchy sound as they rub against each other when you breathe. Doctors call this a pleural friction rub. If your doctor hears the friction rub, he or she will know that you have pleurisy. If you have a pleural effusion, fluid buildup in the pleural space will prevent a friction rub. But if you have a lot of fluid, your doctor may hear a dull sound when he or she taps on your chest.
