The Stem Cell Debate: Is it Over? – Genetics

Posted: Published on May 23rd, 2018

Regulations and policies change frequently to keep up with the pace of research, as well as to reflect the views of different political parties. Here President Obama signs an executive order on stem cells, reversing some limits on federal research funding. (White House photo by Chuck Kennedy) Governments around the globe have passed legislation to regulate stem cell research. In the United States, laws prohibit the creation of embryos for research purposes. Scientists instead receive "leftover" embryos from fertility clinics with consent from donors. Most people agree that these guidelines are appropriate. Disagreements surface, however, when political parties debate about how to fund stem cell research. The federal government allocates billions of dollars each year to biomedical research. But should taxpayer dollars be used to fund embryo and stem cell research when some believe it to be unethical? Legislators have had the unique challenge of encouraging advances in science and medicine while preserving a respect for life. U.S. President Bush, for example, limited federal funding to a study of 70 or so hES cell lines back in 2001. While this did slow the destruction of human embryos, many believe the restrictions set back the progress of stem cell research. President … Continue reading →

Cardiac Stem Cell Research – Cedars-Sinai

Posted: Published on May 22nd, 2018

Results from a ground-breaking Smidt Heart Institute clinical trial show that an infusion of cardiac stem cells helps damaged hearts regrow healthy muscle. The first-in-man clinical trial, based on technologies and discoveries made by Eduardo Marbn, MD, PhD, and led by Raj Makkar, MD, explored the safety of harvesting, growing and giving patients their own cardiac stem cells to repair heart tissue injured by heart attack. The study's findings, published in The Lancet, show that heart attack patients who received stem cell treatment demonstrated a significant reduction in the size of the scar left on the heart muscle; this is a pioneering stem cell result, says Marban, who notes the study shows actual regeneration of tissues. With support from the California Institute for Regenerative Medicine, the Heart Institute team is now planning future clinical trials to treat advanced heart disease patients with stem cells. The process to grow cardiac-derived stem cells involved in the study was developed earlier by Marbn when he was on the faculty of Johns Hopkins University. The university has filed for a patent on that intellectual property, and has licensed it to a company in which Marbn has a financial interest. No funds from that company … Continue reading →

Welcome to the ABG Tutorial – Welcome to Hansen Nursing

Posted: Published on May 22nd, 2018

A note about pre-requisite learning: A clear understanding of human acid-base physiology is necessary before you begin this learning activity An introduction to acid-base imbalances will facilitate your understanding of the contents within this tutorial. Upon completion of this learning activity, you will be able to orecognize clinical manifestations associated with acid-base imbalances. omatch pH values with acid-base imbalances. oselect the correct answer following the review of each case study. ocompare and contrast the step-wise assessment of determining the acid-base balance of the blood. oidentify the appropriate etiology of metabolic acidosis/alkalosis and respiratory acidosis/alkalosis. odifferentiate between compensatory and non-compensatory ABG changes. Sometimes reading and deciphering Arterial Blood Gases (ABGs) can be a challenge! I have provided an interactive online tutorial for your review. Arterial blood gas values reflect ventilation and acid-base balance. The results include the arterial blood pH (concentration of hydrogen ions in the blood) , partial pressure of carbon dioxide (PaCO2) dissolved in the arterial plasma, and the concentration of sodium bicarbonate (HCO3-) in the blood. Our bodies regulate an acid-base balance through a "buffer system." This buffer system neutralizes acids. There are three buffer systems that exist for the maintenance of our acid-base equilibrium: a buffer system … Continue reading →

Cardiac catheterization – Mayo Clinic

Posted: Published on May 22nd, 2018

Overview Cardiac catheterization (kath-uh-tur-ih-ZAY-shun) is a procedure used to diagnose and treat cardiovascular conditions. During cardiac catheterization, a long thin tube called a catheter is inserted in an artery or vein in your groin, neck or arm and threaded through your blood vessels to your heart. Using this catheter, doctors can then do diagnostic tests as part of a cardiac catheterization. Some heart disease treatments, such as coronary angioplasty, also are done using cardiac catheterization. Usually, you'll be awake during cardiac catheterization, but given medications to help you relax. Recovery time for a cardiac catheterization is quick, and there's a low risk of complications. Mayo Clinic's approach Cardiac catheterization is done to see if you have a heart problem, or as a part of a procedure to correct a heart problem your doctor already knows about. If you're having cardiac catheterization as a test for heart disease, your doctor can: Cardiac catheterization is also used as part of some procedures to treat heart disease. These procedures include: Angioplasty with or without stent placement. Angioplasty involves temporarily inserting and expanding a tiny balloon at the site of your blockage to help widen a narrowed artery. Angioplasty is usually combined with implantation … Continue reading →

If you or a loved one is one of the millions of people suffering from eczema on your face, you probably feel very frustrated at each recurrence of the redness, pimple-like bumps, discoloration, inflammation, and sometimes oozing lesions. When eczema occurs in the face and neck it can have a profound impact on every aspect of your life and you may become desperate for relief. This is easy to understand, you greet the world with your face and you may feel the world looks on you differently when you have a recurrence. Photo credit: kthrn Facial eczema, sometimes called excema, is very common in infants and young children. In fact, it is normally the first area affected in this type of atopic eczema. These cases typically clear up by adolescence, but they can recur later in life. However, it is the adult onset of eczema in the facial area that can be more severe, cause greater discomfort, and very negatively impact your quality of life. Fortunately, this type of facial eczema can be the most responsive to safe and natural treatments. Some of the traditional medical treatments, like topical steroid creams, are not as effective on facial eczema as more … Continue reading →

anon950526Post 156 Is there any impact due to this? Obviously, some of you dont have kids. The life of a child is worth so much more than any adult. You got to live. What if that embryo happened to be you? Would you then feel that it is OK to conduct this research? I am a mother of two, soon to be three. I don't care about any of that just long as my kids at least get a chance at living and there is a God. I had a 50 percent chance of having babies because of a huge benign tumor that grew on my left ovary and killed my left fallopian tube. I prayed for my babies and got them every time. Besides that, everybody has their I watched this gruesome abortion video and the lady was 12 weeks along. You could see the child trying to fight for its life. Murder is murder. Helping to save other people or not -- that's like you seeing a man trying to rape a woman and you shoot him dead. It's the same if you were trying to save her life but you get persecuted and convicted for taking matters … Continue reading →

High blood pressure (hypertension) – Symptoms and causes …

Posted: Published on May 18th, 2018

Overview High blood pressure is a common condition in which the long-term force of the blood against your artery walls is high enough that it may eventually cause health problems, such as heart disease. Blood pressure is determined both by the amount of blood your heart pumps and the amount of resistance to blood flow in your arteries. The more blood your heart pumps and the narrower your arteries, the higher your blood pressure. You can have high blood pressure (hypertension) for years without any symptoms. Even without symptoms, damage to blood vessels and your heart continues and can be detected. Uncontrolled high blood pressure increases your risk of serious health problems, including heart attack and stroke. High blood pressure generally develops over many years, and it affects nearly everyone eventually. Fortunately, high blood pressure can be easily detected. And once you know you have high blood pressure, you can work with your doctor to control it. Most people with high blood pressure have no signs or symptoms, even if blood pressure readings reach dangerously high levels. A few people with high blood pressure may have headaches, shortness of breath or nosebleeds, but these signs and symptoms aren't specific and … Continue reading →
