pacemaker cells mitochondria

Healthy functionally active mitochondria are taken from a donor’s oocyte and integrated with the patient’s cells. Next, fertilization with sperm and transfer of a healthy embryo into the patient’s uterus is performed.

Anti-mitochondrial antibodies (AMA) are autoantibodies, consisting of immunoglobulins formed against mitochondria,[1] primarily mitochondria in cells of the liver. The presence of AMAs in the blood or serum of a person is indicative of several autoimmune diseases such as primary biliary cirrhosis (PBC) (a scarring of liver tissue, confined primarily to the bile duct drainage system of the liver). It is present in about 95% of cases.

The new method focuses on mitochondria, small particles within cells that act as batteries which provide energy to the cell. Mitochondria contain their own genetic material, which is separate from the nuclear genetic material containing sperm and egg. The goal of scientists is to prevent the genetic material of damaged mitochondria to be transferred to the next generation of the mother. About 200 children a year are born with mutations in mitochondrial DNA.

Chemotherapy drugs damage the mitochondria in cancer cells. When mitochondria are damaged, they send signals to the cell to die. That's one way chemotherapy drugs kill cancer cells. According to the link you posted, Vitamin C protects the mitochondria, therefore preventing chemotherapy drugs from working well. But on the other hand, the Hepatitis C virus damages the mitochondria in liver cells (by a process of oxidation).

Diseases of the mitochondria cause the most damage to cells of organs and systems that require a great deal of energy: the brain, the heart, the skeletal muscles, the kidney, liver and the endocrine and respiratory systems.

This can happen in certain chronic conditions where mitochondria are stressed. Unfortunately, in many chronic conditions our mitochondria are stressed, and especially when intracellular infections are present that cause oxidative stress to our mitochondria. (The cardiolipin molecules in the inner mitochondrial membrane are expecially sensitive to excess oxidative stress and once oxidized they can be released from cells.

uk I have read so many articles about CFS that detail possible causes and proposed treatment plans, but no other doctor had illustrated, step by step, just how the mitochondria in our cells make energy so that they can function. She explains it all very clearly, although it is a complex bio-chemical process. I still don't know what caused my mitochondria to malfunction in the first place, but at least now I understand what I'm doing to my body when I PUSH myself through my day.

could anybody please tell me what actually mitochondria is an what happens with axonal outgrowth and how it affects the body with thanks

heart pacemaker and now have muscle damage requiring close watch and future change in pacemaker; clonus movements from time to time; weakness in right arm and knees. Over the past 3 years, MS, ALS, Lyme's lupus, you name it has been ruled out. I will have a muscle biopsy at UVA on the 22nd. My neurologist is leaning toward a mitochondrial disorder, which is why he ordered the biopsy. The last EMG he did showed some abnormalities (in the past, it would always be normal).

I have been watching a documentry presented by an anaesthetist, regarding lowering body temperature during surgery. It all came about when a woman Doctor in Norway was skiing and fell through some cracked ice, trapping herself in frozen water. It was several hours before she got to the hospital and was actually considered dead because of her pupils and having no brain activity. They put her onto a bypass machine which gradually warmed her blood and her heart actually started beating again.

You have suffered a great injustice, and I'm sorry for your experience. I do not know what the black substance was, or what the results of exposure may be. However, the skipped beats may be caused simply by confusion in the heart muscle itself. Your heart cells are all capable of contracting and causing the heart to beat. Usually, this job is segregated to specific cells that most people refer to as the "natrual pacemaker.

s the same kind of confused stuff as before, only instead of researching immune cells, I went a little higher up the chain of command, to the Outer Membrane of the Mitochondria. Sounds like a Star Trek episode right? "Mr. Sulu, set a course for the outer membrane of the mitochondria." Anyway, I've always liked coming here. The place is always full of inquisitive people, and I need help with my information.

Correction of thyroid hormones without repairing your mitochondria (the little batteries inside your cells that produce energy) can help but doing both is best.

The spread of electricity throughout the heart muscle is possible because all heart muscle cells, not just pacemaker cells, are excitable. Usually, the heart muscle cells keep time more slowly than normal pacemaker cells. This allows the pacemaker cells within the SA node to be in control of generating and pacing the heartbeat.

Hi, am doing some research. please can you explain why an 89yr old with pacemaker kept her 70bpm pulse with a fever of 40 deg.C. Also what were the metabolic implications for her? Many thanks.

The sinoatrial node (SA node) is a group of cells positioned on the wall of the right atrium, near the entrance of the superior vena cava. Cells in the SA node will naturally discharge at about 70-80 times per minute. Because the sinoatrial node is responsible for the rest of the heart's electrical activity, it is sometimes called the primary pacemaker, the natural pacemaker.

Cytochrome P450 is located on the inner membrane of the mitochondria of liver cells (the mitochondria is the powerplant of the cell...it stores oxygen to power the cell). CYP450, is a target of the hepatitis C virus. The virus gets help from CYP450. Why does HCV target the mitochondria? Because the mitochondria is the location of the interferon response mechanism. By damaging the mitochondria, the Hep C virus stops the interferon response.

The spread of electricity throughout the heart muscle is possible because all heart muscle cells, not just pacemaker cells, are excitable. Usually, the heart muscle cells keep time more slowly than normal pacemaker cells. This allows the pacemaker cells within the SA node to be in control of generating and pacing the heartbeat.

I was reading the pathology report for the 2005 FNA and it says Occasional Hurthle cells are seen in the background, and Occasional Hurthle cells are identified in the background. When you google Hurthle, you get thyroid cancer. So, have any of you guys had Hurthle cells and not cancer?? I'm totally confused (which is getting to be pretty normal around here. . . ) Thanks in advance for your help figuring *this* out!! Tricia S. : ) (no surgery yet!

By the way...I noticed the ??? near the "natural pacemaker" portion of your post. Thought I'd take a minute to help you understand. The sinus atrial node is a clump of cells in your heart that put out an electrical current that causes the rest of your cells in the atrial center of your heart to contract. The electrical current continues into the ventricular node and causes the bottom of the heart to contract immediately after that.

Yes, the condition can infect the heart's natural pacemaker. The heart's "natural" pacemaker is called the sinoatrial (SA) node or sinus node. It's a small mass of specialized cells in the top of the heart's right atrium (upper chamber). It makes the electrical impulses that cause your heart to beat.

For two years i have been dealing with a neurologist and a metabolic doctor who both diagnosed me with mitochondria however my muscle biopsy results came back saying i did have features of mitochondria but not ones good enough to say this is whats effecting my walk.So the metabolic doctor said she would not be able to help me and that i didnt have mitochondria but the neurologist thinks different.

If the cells are dead, a cath would not be of any help. If the cells are hibernating due to low blood flow to the area, medication can increase the blood flow to the area....angina with stress and rest normal blood flow. Your symptoms, if any, would be the issue to correct. If you are having chest pain (angina) with exertion and rest relieves the chest pain that would be stable angina and medication can be effective.

Acetyl L-Carnitine is an amino acid that acts in the mitochondria (the powerhouse) within the cells. It gives the mitochondria something more than glucose and fructose to chew on to provide a little more "kick" in the energy the mitochondria provides to the cell. My MS neuro prescribed me these a year ago. I take 1500 mg in the morning, and another 1500 mg late in the afternoon when I take my 2nd dose of Baclofen.

It is very important where to buy the supplements, as some of them are produced in a way much better accessible for your cells (and providing more energy) than the others. I hope, your Dr advised you on that. 4) There is a great website of the United Mitochondrial Disease Foundation http://www.umdf.org/. You can find all the information you need, including the genetic testing and inheritance.

hey jennafa22, Welcome to the forum. Typical of a pathogenic infectious condition which has caused thyroid dysfunction (hypothyroidism) , muscular and central nervous system disease( MS) . Also typical are your side effects of synthroid. In autoimmune disease, in cases like yours, it is probably the consequence of the body attacking its own cells because of a pathogen hiding within the cells.
