ELISA
ELISA Magdy 5,823 Views • 3 years ago

The purpose of an ELISA is to determine if a particular protein is present in a sample and if so, how much. There are two main variations on this method: you can determine how much antibody is in a sample, or you can determine how much protein is bound by an antibody. The distinction is whether you are trying to quantify an antibody or some other protein. In this example, we will use an ELISA to determine how much of a particular antibody is present in an individuals blood.

ELISAs are performed in 96-well plates which permits high throughput results. The bottom of each well is coated with a protein to which will bind the antibody you want to measure. Whole blood is allowed to clot and the cells are centrifuged out to obtain the clear serum with antibodies (called primary antibodies). The serum is incubated in a well, and each well contains a different serum (see figure below). A positive control serum and a negative control serum would be included among the 96 samples being tested.

Debulking Cytoreduction Surgery

Debulking is the surgical removal of part of a malignant tumour which cannot be completely excised, so as to enhance the effectiveness of radiation or chemotherapy. It is used only in specific malignancies, as generally partial removal of a tumor is not considered a worthwhile intervention. Ovarian carcinoma and some types of brain tumor are debulked prior to commencing radio- or chemotherapy. It may also be used in the case of slow growth tumors to shift tumor cells from phase of cell cycle to replicative pool.

Palmitoylethanolamide in glaucoma, retinoprotection and improving ou
Palmitoylethanolamide in glaucoma, retinoprotection and improving ou jan keppel hesselink 1,910 Views • 3 years ago

Recent studies show that administration of PEA in glaucoma patients has a double effect, decrease the IOP and neuroprotection. The IOP is the major risk factor in glaucoma, constricts blood vessels and reduces the delivery of oxygen and nutrients to the retina and optic nerve (ON), causing a process of ischemia and cell death (apoptosis).
New research points out palmitoylethanolamide has a dual action in glaucoma:

1. It reduces high eye pressure by promoting fluid flow out of the eye, and

2. PEA protects nerve cells and retina cells via its neuroprotective and reparative properties.

In the Youtube the essence of the natural treatment of glaucoma with palmitoylethanolamide has been summarized. Daily dose: 2-3 times 400 mg palmitoylethanolamide.

Tracheotomy Procedure Medical Animation
Tracheotomy Procedure Medical Animation Mohamed Ibrahim 39,029 Views • 3 years ago

Tracheotomy is a surgical procedure which consists of making an incision on the anterior aspect of the neck and opening a direct airway through an incision in the trachea (windpipe). The resulting stoma (hole), or tracheostomy, can serve independently as an airway or as a site for a tracheostomy tube to be inserted; this tube allows a person to breathe without the use of his or her nose or mouth. Both surgical and percutaneous techniques are widely used in current surgical practice. It is among the oldest described procedures.

Breast Cancer Screening Recommendations Breast cancer screening is important for all women. If you are at higher risk of breast cancer, you may need to be screened earlier and more often than women at average risk. Breast cancer screening is only recommended for some men at very high risk due to an inherited gene mutation or a strong family history of breast cancer.

Epstein–Barr Virus
Epstein–Barr Virus samer kareem 1,887 Views • 3 years ago

The virus was first discovered in 1964 when Sir Michael Anthony Epstein and Ms. Yvonne Barr found it in a Burkitt lymphoma cell line. In 1968, the virus was linked to the disease infectious mononucleosis. Infection with Epstein-Barr virus (EBV) is common and usually occurs in childhood or early adulthood. EBV is the cause of infectious mononucleosis (also termed "mono"), an illness associated with fever, sore throat, swollen lymph nodes in the neck, and sometimes an enlarged spleen. It is also known as human herpes virus 4. Although EBV can cause mononucleosis, not everyone infected with the virus will get mononucleosis. Less commonly, EBV can cause more serious disease. Symptoms caused by EBV are usually mild and self-limited, but the virus persists in the body for life. It can be reactivated quietly without causing symptoms and may contaminate saliva. Thus, otherwise healthy people can spread the virus to uninfected people through kissing or sharing

Shoulder Cortisone Injections
Shoulder Cortisone Injections samer kareem 2,020 Views • 3 years ago

Corticosteroid Injections – Doctors sometimes inject corticosteroids directly into the knee joint for quick relief of pain and inflammation. Their benefits may last anywhere from a few days to more than six months. While the injections bring targeted relief to the joint and lack many of the side effects of oral corticosteroid medications, they are not without risks. Repeated knee injections may actually contribute to cartilage breakdown. For that reason your doctor will likely put a limit on the number of injections you can receive.

Atrial Fibrillation ECG
Atrial Fibrillation ECG samer kareem 3,104 Views • 3 years ago

AFib is caused by abnormal electrical impulses in the atria, which are the upper chambers of the heart. The result is a rapid and irregular pumping of blood through the atria. These chambers fibrillate, or quiver, rapidly.

Intra-aortic Balloon Pump
Intra-aortic Balloon Pump samer kareem 3,168 Views • 3 years ago

An intra-aortic balloon pump (IABP) is a mechanical device that helps the heart pump blood. This device is inserted into the aorta, the body's largest artery. It is a long, thin tube called a catheter with a balloon on the end of it. If you are hospitalized, your doctor may insert an IABP. Your doctor will numb an area of your leg and thread the IABP through the femoral artery in your leg into your aorta. He or she then positions the IABP at the center of your aorta, below your heart. The doctor will use an X-ray machine during this procedure to help accurately position the IABP. Why is it used? An IABP might be used to stabilize a person who is in the hospital for acute mitral valve regurgitation or severe heart failure. An IABP is only used for a short period of time (hours to days). A long-term treatment will likely be needed, such as valve surgery or the insertion of a left ventricular assist device (LVAD).

Irregular Menstrual Cycle
Irregular Menstrual Cycle samer kareem 1,717 Views • 3 years ago

Menstruation is the time of month when the womb (uterus) sheds its lining and vaginal bleeding occurs. This is known as a menstrual period. Periods vary widely from woman to woman. Some periods are punctual, some are unpredictable. On average, a woman gets her period every 24 to 38 days. A period usually lasts about two to eight days. Irregular periods may require treatment. What Are Irregular Periods? You may have irregular periods if: The time between each period starts to change. You are losing more or less blood during a period than usual. The number of days that your period lasts varies significantly. There are different terms for different types of irregular periods: Irregular Menstrual Bleeding (IrregMB): Bleeding of more than 20 days in individual cycle lengths over a period of one year. Absent Menstrual Bleeding (amenorrhea): No bleeding in a 90-day period. Heavy Menstrual Bleeding (HMB): Excessive menstrual blood loss that interferes with the woman’s physical, emotional, social, and material quality of life and can occur alone or in combination with other symptoms. Heavy and Prolonged Menstrual Bleeding (HPMB): Less common than HMB. It is important to make a distinction from HMB given they may have different etiologies and respond to different therapies. Light Menstrual Bleeding: Based on patient complaint, rarely related to pathology.

Endocarditis
Endocarditis samer kareem 2,448 Views • 3 years ago

Endocarditis is an infection of the inner lining of your heart (endocardium). Endocarditis generally occurs when bacteria or other germs from another part of your body, such as your mouth, spread through your bloodstream and attach to damaged areas in your heart. Left untreated, endocarditis can damage or destroy your heart valves and can lead to life-threatening complications. Treatments for endocarditis include antibiotics and, in certain cases, surgery. Endocarditis is uncommon in people with healthy hearts. People at greatest risk of endocarditis have damaged heart valves, artificial heart valves or other heart defects.

Irritable Bowel Syndrome
Irritable Bowel Syndrome samer kareem 3,885 Views • 3 years ago

Irritable bowel syndrome (IBS) is a common disorder that affects the large intestine (colon). Irritable bowel syndrome commonly causes cramping, abdominal pain, bloating, gas, diarrhea and constipation. IBS is a chronic condition that you will need to manage long term. Even though signs and symptoms are uncomfortable, IBS — unlike ulcerative colitis and Crohn's disease, which are forms of inflammatory bowel disease — doesn't cause changes in bowel tissue or increase your risk of colorectal cancer. Only a small number of people with irritable bowel syndrome have severe signs and symptoms. Some people can control their symptoms by managing diet, lifestyle and stress. Others will need medication and counseling.
