A circulatory anastomosis is a connection (an anastomosis) between two blood vessels, such as between arteries (arterio-arterial anastomosis), between veins (veno-venous anastomosis) or between an artery and a vein (arterio-venous anastomosis). An end artery (or terminal artery) is an artery that is the only supply of oxygenated blood to a portion of tissue. Examples of an end artery include the splenic artery that supplies the spleen and the renal artery that supplies the kidneys.
Folic acid, which is also called folate, is a B vitamin. The best food sources of folic acid are fortified cereals. Folic acid plays an important role in the production of red blood cells and helps your baby's neural tube develop into her brain and spinal cord.
Gallbladder cancer is cancer that begins in the gallbladder. Your gallbladder is a small, pear-shaped organ on the right side of your abdomen, just beneath your liver. The gallbladder stores bile, a digestive fluid produced by your liver. Gallbladder cancer is uncommon. When gallbladder cancer is discovered at its earliest stages, the chance for a cure is very good. But most gallbladder cancers are discovered at a late stage, when the prognosis is often very poor. Gallbladder cancer is difficult to diagnose because it often causes no specific signs or symptoms. Also, the relatively hidden nature of the gallbladder makes it easier for gallbladder cancer to grow without being detected.

Simple microinstruments and a medical school laboratory microscope were used for anastomosis training. Chicken blood vessels were used as a material for this study. A long segment of blood vessel from the proximal brachial artery to the distal radial artery was used for training. End-to-side anastomosis was practiced first, and the training continued with end-to-end anastomosis of the appropriate segments.
Heart failure can be ongoing (chronic), or your condition may start suddenly (acute). Heart failure signs and symptoms may include: Shortness of breath (dyspnea) when you exert yourself or when you lie down Fatigue and weakness Swelling (edema) in your legs, ankles and feet Rapid or irregular heartbeat Reduced ability to exercise Persistent cough or wheezing with white or pink blood-tinged phlegm Increased need to urinate at night Swelling of your abdomen (ascites) Sudden weight gain from fluid retention Lack of appetite and nausea Difficulty concentrating or decreased alertness Sudden, severe shortness of breath and coughing up pink, foamy mucus Chest pain if your heart failure is caused by a heart attack
Nasal polyps are associated with inflammation of the lining of your nasal passages and sinuses that lasts more than 12 weeks (chronic rhinosinusitis, also known as chronic sinusitis). However, it's possible — and even somewhat more likely — to have chronic sinusitis without nasal polyps. Nasal polyps themselves are soft and lack sensation, so if they're small you may not be aware you have them. Multiple growths or a large polyp may block your nasal passages and sinuses.
Occupational respiratory disease is any lung condition you get at work. Certain workplaces lend themselves to disease. The most common are coalmines and factories or areas with high amounts of toxins. These include asbestos and silica dust, as well as smoke, fumes, gases, and other particles. Types of occupational respiratory disease include: coal workers’ pneumoconiosis, also known as Black Lung Disease asbestosis silicosis farmers’ lung, also known as allergic alveolitis. It also includes forms of asthma, bronchitis, or emphysema.
Nasal polyps are soft, painless, noncancerous growths on the lining of your nasal passages or sinuses. They hang down like teardrops or grapes. They result from chronic inflammation due to asthma, recurring infection, allergies, drug sensitivity or certain immune disorders. Small nasal polyps may not cause symptoms. Larger growths or groups of nasal polyps can block your nasal passages or lead to breathing problems, a lost sense of smell and frequent infections. Nasal polyps can affect anyone, but they're more common in adults. Medications can often shrink or eliminate nasal polyps, but surgery is sometimes needed to remove them. Even after successful treatment, nasal polyps often return.
Take your left leg and place your ankle against the knee. Hold the position for a moment before changing legs. This helps stretch the tiny piriformis muscle, which sometimes becomes inflamed and presses against the sciatic nerve causing pain. Repeat by switching sides and doing the same exercise with the other leg.
