Paracentesis is a procedure to take out fluid that has collected in the belly (peritoneal fluid). This fluid buildup is called ascites . Ascites may be caused by infection, inflammation, an injury, or other conditions, such as cirrhosis or cancer. The fluid is taken out using a long, thin needle put through the belly.
Cervical cancer occurs when abnormal cells on the cervix camera.gif grow out of control. The cervix is the lower part of the uterus that opens into the vagina. Cervical cancer can often be successfully treated when it's found early. It is usually found at a very early stage through a Pap test.
This medical animation shows laparoscopically assisted gallbladder removal surgery, or cholecystectomy. The animation begins by showing the normal anatomy of the liver and gallbladder. Over time, gallstones form within the gallbladder, blocking the cystic duct, and causing the gallbladder to become enlarged and inflamed. The procedure, sometimes called a "lap-chole", begins with the insertion of four trocar devices, which allow the physician to see inside the abdomen without making a large incision. Air is added to the abdominal cavity to make it easier to see the gall bladder. Next, we see a view through the laparascope, showing two surgical instruments grasping the gallbladder while a third severs the cystic duct. After the gallbladder is removed, the camera pans around to show that the cystic artery and vein, have already been clipped to prevent bleeding.

Asthma is a condition in which your airways narrow and swell and produce extra mucus. This can make breathing difficult and trigger coughing, wheezing and shortness of breath. For some people, asthma is a minor nuisance. For others, it can be a major problem that interferes with daily activities and may lead to a life-threatening asthma attack. Asthma can't be cured, but its symptoms can be controlled. Because asthma often changes over time, it's important that you work with your doctor to track your signs and symptoms and adjust treatment as needed.
The most popular and one of the principal stains in histology is hematoxylin and eosin stain. It gives us an overview of the tissue and its structure. Hematoxylin binds with basophilic structures – for example DNA and RNA. So we can observe nuclei stained in blue or purple color. Eosin binds to acidophilic substances such as positively charged amino acid side chains. So as the result cytoplasm is pink or orange. All samples in laboratory are stained with H&E. There are several different types of hematoxylins and eosins used in histology which will give us different results.
In this video you will see, how we stain slides with different types of hematoxylins and eosins. Finally, we will compare the results.
