Every 10 minutes, someone is added to the national transplant waiting list, and every day, 22 people on average die waiting for a match, according to the United Network for Organ Sharing. But, thanks to innovations in bioengineering, all of that could change. Conceived nearly 60 years ago, the total artificial heart (TAH) has helped sustain the sickest biventricular failure patients waiting for a transplant. While the design of the primary TAH used today has mostly remained stagnant since the ’80s, when it was first implanted in a patient, new models and clinical trials may lead to a better device and, one day, a permanent solution. “We are still many years away from that,” Dr. Nader Moazami, director of the Cardiac Transplantation and Ventricular Assist Device Therapy Program at the Cleveland Clinic, told FoxNews.com of a permanent artificial heart. “Although tremendous strides have been made, biocompatibility will always remain a challenge.”
Cushing's disease is a serious condition of an excess of the steroid hormone cortisol in the blood level caused by a pituitary tumor secreting adrenocorticotropic hormone (ACTH). ACTH is a hormone produced by the normal pituitary gland. ACTH stimulates the adrenal glands (located on top of the kidneys) to produce cortisol, commonly referred to as the stress hormone.
Cardiovascular disease (CVD) is a general term that describes a disease of the heart or blood vessels. Blood flow to the heart, brain or body can be reduced as the result of a blood clot (thrombosis), or by a build-up of fatty deposits inside an artery that cause the artery to harden and narrow (atherosclerosis).

Broca's Aphasia (expressive) When a stroke injures the frontal regions of the left hemisphere, different kinds of language problems can occur. This part of the brain is important for putting words together to form complete sentences. Injury to the left frontal area can lead to what is called Broca's aphasia.
Our nervous system is involved in everything our body does, from maintaining our breath to controlling our muscles. Our nerves are vital to all we do; therefore, nerve pain and damage can heavily influence our quality of life. In Discovery News' latest video, "Why Can't We Reverse Nerve Damage?" host Lissette Padilla explains the central nervous system (CNS) has certain proteins that inhibit cell regeneration, because each cell in the nervous system has a unique function on the pathway, like a circuit, and can't be replaced.
Lewy body dementia, also known as dementia with Lewy bodies, is the second most common type of progressive dementia after Alzheimer's disease dementia. Protein deposits, called Lewy bodies, develop in nerve cells in the brain regions involved in thinking, memory and movement (motor control). Lewy body dementia causes a progressive decline in mental abilities. People with Lewy body dementia may experience visual hallucinations, and changes in alertness and attention. Other effects include Parkinson's disease-like symptoms such as rigid muscles, slow movement and tremors.
If your knee is severely damaged by arthritis or injury, it may be hard for you to perform simple activities, such as walking or climbing stairs. You may even begin to feel pain while you are sitting or lying down. If nonsurgical treatments like medications and using walking supports are no longer helpful, you may want to consider total knee replacement surgery. Joint replacement surgery is a safe and effective procedure to relieve pain, correct leg deformity, and help you resume normal activities. Knee replacement surgery was first performed in 1968. Since then, improvements in surgical materials and techniques have greatly increased its effectiveness. Total knee replacements are one of the most successful procedures in all of medicine. According to the Agency for Healthcare Research and Quality, more than 600,000 knee replacements are performed each year in the United States. Whether you have just begun exploring treatment options or have already decided to have total knee replacement surgery, this article will help you understand more about this valuable procedure.
Dieta Alcalina Recetas, Listado De Alimentos Alcalinos, Que Es El Agua Alcalina, Menu Para Adelgazar-- http://dieta-alcalina-alimentos.good-info.co -- Entendiendo los Efectos del nivel de pH en el cuerpo El nivel de pH en el cuerpo tiene la habilidad de afectar cada célula del cuerpo. Cuando la sangre tiene un pH alcalino en vez de un pH ácido, ocurre un efecto positivo en cada función corporal del sistema. El cerebro, el sistema circulatorio, los nervios, los músculos, el sistema respiratorio, el sistema digestivo y reproductivo se pueden beneficiar de un nivel adecuado de pH. Por otro lado, cuando el pH del cuerpo es muy ácido, es susceptible a muchas enfermedades y problemas. Ganancia de peso, enfermedades del corazón, envejecimiento prematuro, fatiga, problemas nerviosos, alergias, enfermedades musculares y cáncer son las más probables a ocurrir cuando el pH del cuerpo no está al nivel óptimo. Ya que todos estos problemas son más probables a ocurrir cuando el pH del cuerpo está muy ácido, tiene sentido consumir una dieta rica en alimentos alcalinos. El objetivo principal es usualmente comer aproximadamente entre 75-80% de alimentos alcalinos junto con solamente entre 20-25% de alimentos ácidos. Si se mantiene este nivel en la dieta, el resultado final es un nivel de pH bajo en el cuerpo, el que se requiere para una salud óptima.
