Pulmonary circulation is the portion of the cardiovascular system which carries deoxygenated blood away from the heart, to the lungs, and returns oxygenated (oxygen-rich) blood back to the heart. The function of pulmonary circulation is to exchange carbon dioxide for oxygen in the blood. It is the passage of blood from the heart to the capillaries of the lungs, where the gases are exchanged, and back to the heart to be pumped around the body.
Respiratory syncytial virus (RSV) is a virus that causes infections of the lungs and respiratory tract. It's so common that most children have been infected with the virus by age 2. Respiratory syncytial (sin-SISH-ul) virus can also infect adults. In adults and older, healthy children, the symptoms of respiratory syncytial virus are mild and typically mimic the common cold. Self-care measures are usually all that's needed to relieve any discomfort. Infection with respiratory syncytial virus can be severe in some cases, especially in premature babies and infants with underlying health conditions. RSV can also become serious in older adults, adults with heart and lung diseases, or anyone with a very weak immune system (immunocompromised).

A brief description of the mechanisms, types and assessment of chromosomal analyses. Techniques such as standard cytogenetic testing, FISH and array methods are discussed. Indications for testing in prenatal, neonatal and adult periods are also discussed. Deletions, translocations, inversions etc are described, as are mosaicism and aneuploidy.
Macrobiopsy of breast lesions is a complicated procedure when performed with vacuum assisted biopsy tools. The Spirotome is a hand-held needle set that doesn't need capital investment, is ready to use and provides tissue samples of high quality in substantial amounts. In this way quantitative molecular biology is possible with one tissue sample. The Coramate is an automated version of this direct and frontal technology.
Hepatitis A is a highly contagious liver infection caused by the hepatitis A virus. The virus is one of several types of hepatitis viruses that cause inflammation and affect your liver's ability to function. You're most likely to contract hepatitis A from contaminated food or water or from close contact with someone who's infected. Mild cases of hepatitis A don't require treatment, and most people who are infected recover completely with no permanent liver damage. Practicing good hygiene, including washing hands frequently, is one of the best ways to protect against hepatitis A. Vaccines are available for people most at risk.
In this animation it depicts an artery with cholesterol plaque (the yellowish area) which is blocking most of the inside of this artery. Then small cells called platelets become clumped together and cause the red blood cells to form a clot. This is what causes a HEART ATTACK.
Upper gastrointestinal bleeding (sometimes upper GI, UGI bleed, Upper gastrointestinal hemorrhage, gastrorrhagia) refers to bleeding in the upper gastrointestinal tract, commonly defined as bleeding arising from the esophagus, stomach, or duodenum. In fact, the proportion of UGIB cases caused by peptic ulcer disease has declined, a phenomenon that is believed to be due to the use of proton pump inhibitors (PPIs) and H pylori therapy. Duodenal ulcers are more common than gastric ulcers, but the incidence of bleeding is identical for both.
