During normal sleep, you cycle through REM and four stages of non-REM (NREM) sleep numerous times a night. Stage 1 of NREM sleep is the lightest, while stage 4 is the deepest. When you're repeatedly interrupted and can't cycle normally through these types and stages of sleep, you may feel tired, fatigued, and have trouble concentrating and paying attention while you're awake. Sleepiness puts you at greater risk for car wrecks and other accidents.

Cisplatin is in a class of drugs known as platinum-containing compounds used to treat various types of cancers including metastatic testicular and ovarian tumors. The molecule was first discovered in 1845, but did not receive FDA approval until 1978. Today it is known as the "penicillin of cancer drugs," because it is so effective for many different cancers. There are three key players involved in Cisplatin's mechanism: (1) Cisplatin, (2) DNA (3) and an HMG Protein. Most Cisplatin enters the body through active transport, but some molecules are passively defused through the cell membrane. Once in the nucleus, Cisplatin can form an adduct with two consecutive guanine bases within a strand of DNA. The molecule loses its chlorine atoms in exchange for the nitrogen atoms of the target guanines. Cisplatin can bond more tightly with nitrogen because nitrogen balances the platinum charge more effectively than chlorine. It is this adduct-induced DNA bend that allows binding of proteins which contain the high mobility group, HMG domain. Once the protein is bound to the DNA, it inserts a wedge-like phenyl group of phenylalanine 37 into the widened minor groove created by the bend. The tightly bound HMG protein causes destacking of the nucleotide bases, resulting in the DNA helix becoming kinked. In this way, Cisplatin can be thought of as a monkey wrench in the DNA repair system. With the HMG protein bound to the DNA, the modified strand is not repaired properly and so the cell dies. The success of Cisplatin depends on its ratio of efficacy between cancerous and healthy cells.

Atherosclerosis is a narrowing of the arteries caused by a buildup of plaque. It’s also called arteriosclerosis or hardening of the arteries. Arteries are the blood vessels that carry oxygen and nutrients from your heart to the rest of your body. As you get older, fat and cholesterol can collect in your arteries and form plaque. The buildup of plaque makes it difficult for blood to flow through your arteries. This buildup may occur in any artery in your body and can result in a shortage of blood and oxygen in various tissues of your body. Pieces of plaque can also break off, causing a blood clot. Atherosclerosis can lead to heart attack, stroke, or heart failure if left untreated.

Your baby is still tiny, but already your body is changing. Your breasts start to swell and may feel tender. Tiredness, nausea, and a frequent need to pee are common pregnancy symptoms. In your second trimester, your growing uterus gradually rises up out of your pelvis.

This 40 yr male had upper abdominal pain for 3 months. A video-endoscopic examination of esophagus, stomach and duodenum was performed. A large 2.5x2.5 cm chronic ulcer was detected in the first part (bulb) of duodenum. A gastric biopsy was taken for diagnosis of Helicobacter infection and a rapid urease test done which was positive. He received triple therapy (2 antibiotics and acid suppressive drug for one week) to eradicate Helicobacter pylori infection. Ulcer disease showed rapid clinical and endoscopic healing. Eradication of Helicobacter pylori infection led to permanent ulcer cure.

Sever's disease (also known as calcaneal apophysitis) is a type of bone injury in which the growth plate in the lower back of the heel, where the Achilles tendon (the heel cord that attaches to the growth plate) attaches, becomes inflamed and causes pain.

First described by Aubaniac in 1952, central venous catheterization, or central line placement, is a time-honored and tested technique of quickly accessing the major venous system. Benefits over peripheral access include greater longevity without infection, line security in situ, avoidance of phlebitis, larger lumens, multiple lumens for rapid administration of combinations of drugs, a route for nutritional support, fluid administration, and central venous pressure (CVP) monitoring. Central vein catheterization is also referred to as central line placement. Overall complication rates are as high as 15%, [1, 2, 3, 4] with mechanical complications reported in 5-19% of patients, [5, 6, 7] infectious complications in 5-26%, [1, 2, 4] and thrombotic complications in 2-26%. [1, 8] These complications are all potentially life-threatening and invariably consume significant resources to treat. Placement of a central vein catheter is a common procedure, and house staff require substantial training and supervision to become facile with this technique. A physician should have a thorough foreknowledge of the procedure and its complications before placing a central vein catheter. The supraclavicular approach was first put into clinical practice in 1965 and is an underused method for gaining central access. It offers several advantages over the infraclavicular approach to the subclavian vein. At the insertion site, the subclavian vein is closer to the skin, and the right-side approach offers a straighter path into the subclavian vein. In addition, this site is often more accessible during cardiopulmonary resuscitation (CPR) and during active surgical cases. Finally, in patients who are obese, this anatomic area is less distorted.

Do I Need to See My Doctor for Menstrual Cramps? || Common gynaecological problems in women It's perfectly normal to experience mild cramps during your period, and the good news is that these cramps can usually be eased with simple therapies like a heating pad or an over-the-counter pain reliever. However, some women's menstrual cramps may not feel better with these basic remedies. If this is the case for you, making an appointment with your doctor is important. This way you not only get the pain relief you deserve but also ensure there is nothing else going on.

Appendicitis is one of the most common surgical problems. One out of every 2,000 people has an appendectomy sometime during their lifetime. Treatment requires an operation to remove the infected appendix. Traditionally, the appendix is removed through an incision in the right lower abdominal wall. In most laparoscopic appendectomies, surgeons operate through 3 small incisions (each ¼ to ½ inch) while watching an enlarged image of the patient’s internal organs on a television monitor. In some cases, one of the small openings may be lengthened to complete the procedure.
