Yannas had been studying collagen, a protein found in human skin. Teaming up during the 1970s, the two made a polymer (a chemical compound made of multiple repeating units). Using collagen fibers and a long sugar molecule, they formed a porous (full of small holes) material resembling skin.

Dizziness
Dizziness samer kareem 12,492 Views • 2 years ago

Dizziness is a word that is often used to describe two different feelings. It is important to know exactly what you mean when you say "I feel dizzy," because it can help you and your doctor narrow down the list of possible problems. Lightheadedness is a feeling that you are about to faint or "pass out." Although you may feel dizzy, you do not feel as though you or your surroundings are moving. Lightheadedness often goes away or improves when you lie down. If lightheadedness gets worse, it can lead to a feeling of almost fainting or a fainting spell (syncope). You may sometimes feel nauseated or vomit when you are lightheaded. Vertigo is a feeling that you or your surroundings are moving when there is no actual movement. You may feel as though you are off balance, spinning, whirling, falling, or tilting. When you have severe vertigo, you may feel very nauseated or vomit. You may have trouble walking or standing, and you may lose your balance and fall.

Side Effects Of Birth Control Pills

The oral contraceptive pill, commonly known as "the pill," is a hormone-based method of preventing pregnancy. It can also help resolve irregular menstruation, painful or heavy periods, endometriosis, acne, and premenstrual syndrome (PMS). Birth control pills work by preventing ovulation. No egg is produced, so there is nothing for the sperm to fertilize. Pregnancy cannot occur. "The pill" is used by nearly 16 percent of women aged 15 to 44 years in the United States, and it has both advantages and disadvantages. People with different risk factors may be advised to use a particular kind of pill. There are different types of contraceptive pills. They all contain synthetic forms of the hormones estrogen, progesterone, or both. Synthetic progesterone is called progestin. Combination pills contain progestin and estrogen. The "mini pill," contains only progestin. Monophasic pills all contain the same balance of hormones. With phasic pills, two or three different types of pill are taken each month, each with a different balance of hormones.

Can Oral Sex Increase Risk of Cancer?
Can Oral Sex Increase Risk of Cancer? Alicia Berger 19,839 Views • 2 years ago

Oral sex can be an enjoyable, healthy part of an adult relationship. But there are some things that many people don't know about oral sex. Here are four facts that might surprise you. 1. Oral sex is linked to throat cancer. Cancer? Yes, you can get throat cancer from oral sex, says American Cancer Society Chief Medical Officer Otis Brawley, MD. It's not oral sex, per se, that causes cancer, but the human papillomavirus (HPV), which can be passed from person to person during sex, including oral sex.

Complete cardiac transplant
Complete cardiac transplant samer kareem 7,657 Views • 2 years ago

The first operation is harvesting the heart from the donor. The donor is usually an unfortunate person who has suffered irreversible brain injury, called "brain death". Very often these are patients who have had major trauma to the head, for example, in an automobile accident. The victim's organs, other than the brain, are working well with the help of medications and other "life support" that may include a respirator or other devices. A team of physicians, nurses, and technicians goes to the hospital of the donor to remove donated organs once brain death of the donor has been determined. The removed organs are transported on ice to keep them alive until they can be implanted. For the heart, this is optimally less than six hours. So, the organs are often flown by airplane or helicopter to the recipient's hospital.

Closure of Wound by Stress Relaxation
Closure of Wound by Stress Relaxation samer kareem 1,726 Views • 2 years ago

Stress-relaxation is a well-established mechanism for laboratory skin stretching, with limited clinical application in conventional suturing techniques due to the inherent, concomitant induction of ischemia, necrosis and subsequent suture failure. Skin defects that cannot be primarily closed are a common difficulty during reconstructive surgery. The TopClosure tension-relief system (TRS) is a novel device for wound closure closure, providing secured attachment to the skin through a wide area of attachment, in an adjustable manner, enabling primary closure of medium to large skin defects. The aim of this study was to evaluate the efficiency of the TopClosure TRS as a substitute for skin grafting and flaps for primary closure of large soft tissue defects by stress-relaxation. We present three demonstrative cases requiring resection of large to huge tumors customarily requiring closure by skin graft or flaps. TRS was applied during surgery serving as a tension-relief platform for tension sutures, to enable primary skin-defect closure by cycling of stress-relaxation, and following surgery as skin-secure system until complete wound closure. All skin defects ranging from 7 to 26 cm in width were manipulated by the TRS through stress-relaxation, without undermining of skin, enabling primary skin closure and eliminating the need for skin grafts and flaps. Immediate wound closure ranged 26 to 135 min. TRS was applied for 3 to 4 weeks. Complications were minimal and donor site morbidity was eliminated. Surgical time, hospital stay and costs were reduced and wound aesthetics were improved. In this case series we present a novel technology that enables the utilization of the viscoelastic properties of the skin to an extreme level, extending the limits of primary wound closure by the stress-relaxation principle. This is achieved via a simple device application that may aid immediate primary wound closure and downgrade the complexity of surgical procedures for a wide range of applications on a global scale.

Neurotransmission
Neurotransmission samer kareem 1,485 Views • 2 years ago

Ca2+ binds with the membrane of the synaptic vesicles, which causes the vesicles to break and release the neurotransmitter into the synaptic cleft. After the neurotransmitters are released, they diffuse across the synaptic cleft and interact with receptors on the postsynaptic membrane. When the action potential reaches the presynaptic terminal, it provokes the release of a small quantity of neurotransmitter molecules, which bind to chemical receptor molecules located in the membrane of another neuron, the postsynaptic neuron, on the opposite side of the synaptic cleft.
