Fertilization and Implantation in human
Fertilization and Implantation in human samer kareem 3,165 Views • 3 years ago

Millions of sperms are deposited into the vagina during sexual intercourse. The sperms make their way through the cervix into the uterus and then on to the fallopian tubes. As they swim along this way their numbers decline. Only a few hundred sperm will get close to the egg. During the trip, sperm prepare themselves to meet the egg by subtle alterations of their heads and movement patterns. Once inside the fallopian tube, the sperm attracts the egg by releasing a chemical. The egg is surrounded by a protective covering called the zona pellucida, which allows only one sperm to penetrate it. Once inside the egg, the head of the fertilizing sperm releases its genetic contents, which fuses with the nucleus of the egg. Fertilisation is now complete. Sperm are able to survive for 2-3 days within the female's reproductive tract. The length of the time that a woman's egg can be fertilized by a man's sperm ranges from 12-24 hours.

liver abcess
liver abcess samer kareem 1,714 Views • 3 years ago

Bacterial abscess of the liver is relatively rare; however, it has been described since the time of Hippocrates (400 BCE), with the first published review by Bright appearing in 1936. In 1938, Ochsner's classic review heralded surgical drainage as the definitive therapy; however, despite the more aggressive approach to treatment, the mortality remained at 60-80%.[1] The development of new radiologic techniques, the improvement in microbiologic identification, and the advancement of drainage techniques, as well as improved supportive care, have reduced mortality to 5-30%; yet, the prevalence of liver abscess has remained relatively unchanged. Untreated, this infection remains uniformly fatal. The three major forms of liver abscess, classified by etiology, are as follows: Pyogenic abscess, which is most often polymicrobial, accounts for 80% of hepatic abscess cases in the United States Amebic abscess due to Entamoeba histolytica accounts for 10% of cases [2] Fungal abscess, most often due to Candida species, accounts for fewer than 10% of cases

Primary sclerosing  cholangitis
Primary sclerosing cholangitis samer kareem 2,515 Views • 3 years ago

Primary sclerosing (skluh-ROHS-ing) cholangitis (koh-lan-JIE-tis) is a disease of the bile ducts, which carry the digestive liquid bile from your liver to your small intestine. In primary sclerosing cholangitis, inflammation causes scars within the bile ducts. These scars make the ducts hard and narrow and gradually cause serious liver damage. In most people with primary sclerosing cholangitis, the disease progresses slowly and can lead to liver failure, repeated infections, and tumors of the bile duct or liver. Liver transplant is the only known cure for primary sclerosing cholangitis. The search for other treatments to slow or stop primary sclerosing cholangitis is ongoing, and scientists have turned up many promising leads. Until better treatments are proved safe and effective, though, care for primary sclerosing cholangitis focuses on monitoring liver function, managing symptoms and, when possible, doing procedures that temporarily open blocked bile ducts.
