The deep veins play a significant role in propelling blood toward the heart. The one-way valves in deep veins prevent blood from flowing backward, and the muscles surrounding the deep veins compress them, helping force the blood toward the heart, just as squeezing a toothpaste tube ejects toothpaste.

Parkinson's disease is a progressive disorder of the nervous system that affects movement. It develops gradually, sometimes starting with a barely noticeable tremor in just one hand. But while a tremor may be the most well-known sign of Parkinson's disease, the disorder also commonly causes stiffness or slowing of movement. In the early stages of Parkinson's disease, your face may show little or no expression, or your arms may not swing when you walk. Your speech may become soft or slurred. Parkinson's disease symptoms worsen as your condition progresses over time. Although Parkinson's disease can't be cured, medications may markedly improve your symptoms. In occasional cases, your doctor may suggest surgery to regulate certain regions of your brain and improve your symptoms.

When food is taken, it is broken down into smaller components. Sugars and carbohydrates are thus broken down into glucose for the body to utilize them as an energy source. The liver is also able to manufacture glucose. In normal persons the hormone insulin, which is made by the beta cells of the pancreas, regulates how much glucose is in the blood. When there is excess of glucose in blood, insulin stimulates cells to absorb enough glucose from the blood for the energy that they need. Insulin also stimulates the liver to absorb and store any excess glucose that is in the blood. Insulin release is triggered after a meal when there is a rise in blood glucose. When blood glucose levels fall, during exercise for example, insulin levels fall too. High insulin will promote glucose uptake, glycolysis (break down of glucose), and glycogenesis (formation of storage form of glucose called glycogen), as well as uptake and synthesis of amino acids, proteins, and fat. Low insulin will promote gluconeogenesis (breakdown of various substrates to release glucose), glycogenolysis (breakdown of glycogen to release gluose), lipolysis (breakdown of lipids to release glucose), and proteolysis (breakdown of proteins to release glucose). Insulin acts via insulin receptors.

A pancreas transplant is a surgical procedure to place a healthy pancreas from a deceased donor into a person whose pancreas no longer functions properly. Your pancreas is an organ that lies behind the lower part of your stomach. One of its main functions is to make insulin, a hormone that regulates the absorption of sugar (glucose) into your cells. If your pancreas doesn't make enough insulin, blood sugar levels can rise to unhealthy levels, resulting in type 1 diabetes. Most pancreas transplants are done to treat type 1 diabetes. A pancreas transplant offers a potential cure for this condition. But it is typically reserved for those with serious diabetes complications, because the side effects of a pancreas transplant are significant. In some cases, pancreas transplants may also treat type 2 diabetes. Rarely, pancreas transplants may be used in the treatment of pancreatic, bile duct or other cancers. A pancreas transplant is often done in conjunction with a kidney transplant in people whose kidneys have been damaged by diabetes.

Three cholinesterase inhibitors are commonly prescribed: Donepezil (Aricept) is approved to treat all stages of Alzheimer's. Rivastigmine (Exelon) is approved to treat mild to moderate Alzheimer's. Galantamine (Razadyne) is approved to treat mild to moderate Alzheimer's. Currently, there is no cure for Alzheimer's. But drug and non-drug treatments may help with both cognitive and behavioral symptoms. Researchers are looking for new treatments to alter the course of the disease and improve the quality of life for people with dementia. ... Medications for Memory Loss.

A craniotomy is the surgical removal of part of the bone from the skull to expose the brain. Specialized tools are used to remove the section of bone called the bone flap. The bone flap is temporarily removed, then replaced after the brain surgery has been done.

The goal of a decompression surgery is usually to relieve pain caused by nerve root pinching. There are two common causes of lumbar nerve root pressure: from a lumbar herniated disc or lumbar spinal stenosis. This type of pain is usually referred to as a radiculopathy, or sciatica. A decompression surgery involves removing a small portion of the bone over the nerve root and/or disc material from under the nerve root to relieve pinching of the nerve and provide more room for the nerve to heal. The most common types of decompression surgery are microdiscectomy and laminectomy.

Research from Mayo Clinic finds that half of elderly patients who start dialysis after age 75 will die within one year.

Lead study author and a health care delivery scholar with the Mayo Clinic Robert D. and Patricia E. Kern Center for the Science of Health Care Delivery, Dr. Bjorg Thorsteinsdottir says many elderly patients and their families feel that they have no choice but to start dialysis, with several expressing regret from having initiated therapy.

The findings were presented at the American Society of Nephrology's Kidney Week 2013 in Atlanta.

Adult-onset Still's disease (AOSD) is a rare systemic inflammatory disease characterized by the classic triad of persistent high spiking fevers, joint pain, and a distinctive salmon-colored bumpy rash. The disease is considered a diagnosis of exclusion.

The following guidelines are an interpretation of the evidence presented in the 2010 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations1). They apply primarily to newly born infants undergoing transition from intrauterine to extrauterine life, but the recommendations are also applicable to neonates who have completed perinatal transition and require resuscitation during the first few weeks to months following birth. Practitioners who resuscitate infants at birth or at any time during the initial hospital admission should consider following these guidelines. For the purposes of these guidelines, the terms newborn and neonate are intended to apply to any infant during the initial hospitalization. The term newly born is intended to apply specifically to an infant at the time of birth.

Acanthamoeba keratitis is a rare disease in which amoebae invade the cornea of the eye. It may result in permanent visual impairment or blindness.

A ureteral stent, sometimes as well called ureteric stent, is a thin tube inserted into the ureter to prevent or treat obstruction of the urine flow from the kidney. The length of the stents used in adult patients varies between 24 to 30 cm.

A talus fracture is a break in one of the bones that forms the ankle. This type of fracture often occurs during a high-energy event, such as a car collision or a high-velocity fall. Because the talus is important for ankle movement, a fracture often results in significant loss of motion and function. In addition, a talus fracture that does not heal properly can lead to serious complications, including chronic pain. For this reason, many talus fractures require surgery.
