1. Algin (alginate)
This gelatinous material, a polysaccharide extract from brown algae , is widely used in foods, medicines, and industrial and household products. The main algae that produce it are Laminaria species and Macrocystis pyrifera (a chemically different version of algin is produced by the bacterium Azobacter vinelandii.)

2. Amebiasis (amebic dysentery)
Amebiasis is an infection with amoebas (a type of protozoan), particularly Entamoeba histolytica. The disease is contracted by eating food or drinking water that has been infected with encysted forms of the amoebas. The symptoms include diarrhea, weakness, and sometimes jaundice. During the course of the disease, sores and abscesses form on the mucous membrane of the large intestine (sometimes causing perforations), and the abscesses may be carried to the liver via the portal vein. Patients are usually treated with drugs called metronidazole (Flagyl) and chloroquinine; they may need to be medicated for up to three months to clear the infection.

3. Blastocyst (blastodermic vesicle)
A stage in the development of a mammalian embryo just after the blastula stage, where the hollow ball of cells becomes two layers of cells - one layer, called the trophoblast, is at one end of the embryo and attaches it to the wall of the uterus so that it can receive nutrition during its development. The other is a single-cell layer which surrounds the blastocoele , the fluid-filled hollow part of the ball.

4. Blastocyst
The developmental stage of the fertilized ovum by the time it is ready to implant; formed from the morula and consists of an inner cell mass, an internal cavity, and an outer layer of cells (the trophoblast ).

5. Breast ultrasound
Ultrasound can differentiate cysts and solid masses of the breast when x-ray examination of the breast cannot. Ultrasound is often used to localize the mass with a marker (e.g. a wire) which the surgeon uses as a guide to cut out the mass for examination.

6. CA-125 tumor marker
This is a protein measured in blood samples. It is produced by a variety of cells, but particularly by ovarian cancer cells. It is used as a tuomor marker to confirm the suspicion of ovarian cancer and to follow the presence of residual or recurrence of ovarian cancer after surgery. Its blood levels may be elevated in pregnant women and patients with breast and colorectal cancers, endometriosis , ovarian cysts, fibroid s, cirrhosis , hepatitis , or pancreatitis . (Normal range is 0-35 u/mL).

7. Chlamydomonas
A genus of green algae consisting of more than 600 species worldwide, living in marine, freshwater, soil, and even snow environments. They are single cell ed eukaryotic organisms ranging from 5 to 100 micrometers long which can be roughly spherical, egg shaped, or elliptical. Most species have two flagella (coming out the same side) for swimming. Most of the time they are haploid and reproduce by dividing into two ( binary fission ); when they are stressed they can form gamete s which fuse to form diploid cyst s which later divide into four haploid cells. Taxonomically they have been classified under plants, animals, and protist s. Several species from this genus are important model organisms for the study of cell biology , molecular biology , genetics , plant physiology , and biotechnology . The species most commonly used in scientific experiments is Chlamydomonas reinhardtii (also known as C. reinhardi or C. reinhardii).

8. Chloride
This is a serum electrolyte; normal value is 95 - 107 mmol/L. Sweat chloride is measured for the diagnosis of cystic fibrosis; normal value of sweat chloride is 4 - 60 mmol/L. Elevated sweat chloride coupled with clinical picture is diagnostic of this condition.

9. Cholecystectomy
Surgical removal of the gallbladder .

10. Cholecystectomy
This is surgery to remove the gallbladder . Cholecystectomy is indicated for patients with gallstones that cause severe symptoms. If the stones are less than 1 cm in diameter and contain no calcium , dissolution therapy with ursodeoxycholic acid is successful in 50% of the cases at six months of therapy. Shock-wave treatment (extracorporeal shock-wave lithotripsy) is applicable in only about 7% of the patients (with less than 3 stones, total stone diameter less than 20 mm and stone volume less than 15 mL). Only 50% of patients receiving shock-wave therapy have relief of their symptoms. For patients with medical problems severe enough to contraindicate immediate cholecystectomy, percutaneous catheter cholecystostomy may be preferable. For these patients, cholecystecomy can be performed after their general medical condition improves. The operative death rate 0.1% in patient under age 50 and 0.5% in patients over 50. Most deaths occur in patients who have other preoperative medical problems. Delaying cholecystectomy when indicated increases the chance of cholangitis, acute pancreatitis (inflammation of the pancreas ), empyema and perforation of the gallbladder, gallstone ileus and common bile duct obstruction.
