anginarex com Ablation Therapy For Atrial Fibrillation - What Are Ablation Therapy For Atrial Fibrillation? Atrial fibrillation (AF) is a common rhythm abnormality of the heart. Over the years, the incidence of atrial fibrillation is increased, in both the developed and developing world. If you have AF, electrical impulses do not arise normally in the SA node as described above. Instead, many impulses begin simultaneously and spread through the atria and compete for a chance to travel through the AV node. This results in a very rapid, disorganized and irregular heartbeat. The alternative to drug therapy is radiofrequency ablation for atrial fibrillation, however, current medical guidelines still recommend ablation for AF as second-line therapy, meant for patients who have failed drug treatment. Ablation therapy is a type of minimally invasive procedure doctors use to destroy abnormal tissue that occurs with many conditions. For example, a doctor might use an ablation procedure to treat a small kidney tumor or to destroy a small amount of heart tissue that's causing abnormal heart rhythms.

http://graystonemortgagedotcom/ - Interest rates are low and with an economy that seems to be on the rise, people are looking at what options are with home loans.

Mercury Mercury has no known beneficial role in human metabolism, and its ability to affect the distribution and retention of other heavy metals makes it one of the most dangerous toxic metals (Houston 2011). Mercury toxicity can arise from ingestion of metallic mercury or mercury salts (which are generally poorly bioavailable) or by inhalation of mercury vapor (which is readily absorbed) (ATSDR 2001). The relatively high solubility and stability of certain mercury salts in water enables them to be readily taken up and biotransformed to methylmercury by certain fish; these forms are readily absorbed through the GI tract and are becoming a major source of mercury exposure in humans (Houston 2011). Dimethylmercury, a mercury compound chemically synthesized in the laboratory, can also be absorbed through the skin, and several cases of fatal exposure among laboratory workers have been reported (Nierenberg 1998; Bernhoft 2012). Although humans can excrete small amounts of mercury in urine or feces as well as via exhalation or sweating, they lack an active robust mechanism for mercury excretion, allowing levels to accumulate with chronic exposure (Houston 2011; Sällsten 2000; Houston 2011). Mercury, particularly when inhaled as mercury vapors, can distribute to many organs, but may concentrate in the brain and kidneys (ATSDR 2001). It can also cross the placenta and be found in breast milk (Yang 1997). Mercury exerts its toxic effects by competing with and displacing iron and copper from the active site of enzymes involved in energy production; this induces mitochondrial dysfunction and oxidative damage (Houston 2011). Mercury can also directly accelerate the oxidative destruction of cell membranes and LDL cholesterol particles as well as bind to and inactivate the cellular antioxidants N-acetyl cysteine, alpha-lipoic acid, and glutathione (Houston 2011). Because of its effect on cellular defense and energy generation, mercury can cause widespread toxicity and symptoms
