how does digitonin work?

It binds to the sterols in the cells membranes and make them insoluble.  Without the sterols, the cells are much less fluid and more crystalline.  Sterols like cholesterol get a bad rap but they are very necessary!

Amlactin works really well.  It is over the counter.

it probably works fine...but one ingredient in it (guggelsterones) may have some bad side effects.  it could cause higher blood pressure and be harmful to gains (if u workout) by blocking the receptor that produces testosterone.

Yes, researchers know how they work, in detail.  Most of the newer drugs are designed at the molecular level to perform specific functions.  Prozac is a perfect example.  It was the first of what has become an entire class of drugs known as SSRIs, or Selective Serotonin Re-uptake Inhibitors.  Prozac is used to treat Depression.  by design, it increases the amount of available Serotonin, (a neurotransmitter) in the synapses of the brain, by slowing the rate at which the cells that excrete the serotonin can reabsorb it.\n\nThe man who led the design team has said that he did it just to prove he could.

The heart cells are called myocytes that can contract.  Proteins inside the myocyte, actin and myosin, make this contraction possible.  Calcium ions are released very quickly (from the sarcoplasmic reticulum) and trigger the contraction. Then the heart relaxes and gets ready for the next beat.  The contraction is controlled from the top of the heart (the atria) and spreads down to the botton (the ventricles), like a water ripple through a pond but in this case it is through all the cells of the heart.  The coordinated contraction then results in blood being pumped into the lungs and forward through the body.\n\nIf you need a more detalied description let me know.  This is the basic idea though.  The billions of cells of the heart are coordinated to result in proper heart beats.

The laser in the disk writer etches patterns of bumps in a circular pattern on the CD. When the CD is read, a laser follows these paths, and the bumps it hits create an analog singal that is interpreted into a digital signal. \n\nIn a nutshell.

the magnets somehow circulates your blood.  The higher the #, the better they work.  But someone told me that it didnt really do anything for him.  Good luck

Firstly, it should be done by a healthcare professional...either a doctor or a diabetic nurse.  It is calculated based on individual response. So it is really a guess game. You give some insulin, see what a sugar value is in several hours and adjust based on that.  After several days, you arrive at a reasonable dose.  Hope this helps, but don't try this on your own :).

T-tubules transmit nerve impulses throughout the muscle.  Think of it this way.  Your biceps muscle is composed of many different muscle cells working together.  When your brain tells your biceps to contract, does it send individual nerves to every single muscle cell?  No it doesn't (I guess that really isn't an obvious answer).  This is where the T-tubules come in.  They transmit electrical impulses from one muscle cell to another.  This way, only some muscle cells need to be activated by a nerve--the rest will be signaled through the T-tubule network, so that all of the muscle cells will contract together.\n\nSo what happens when you block the T-tubules?  Your muscle doesn't work so well anymore.  You might still get cell-to-cell communication (I'm not sure), but even if you did, it would be slow so that the muscle fibers would not contract synchronously.\n\nAddendum: It's been 6 or 7 years since I last studied physiology, so I think you should listen to the professor, not me!

Foxglove is the source of two potent glycosides used as a heart stimulant, digoxin and digitoxin. They are administered for congestive heart failure, weakened heart and irregular heart beat (arrhythmia). These glycosides prolong the relaxation phase of the heart (ventricular diastole), thus allowing the left ventricle to fill with more blood. In accordance with Starling's Law of Contraction, the increased blood volume in the left ventricle results in a more forceful contraction (ventricular systole), thereby pumping more blood out into the aorta artery. After the contraction, as backflow pushes against the aorta semilunar valve, coronary arteries that feed the heart muscle fill with blood. They are able to fill with blood during diastole because the heart relaxes and the coronary vessels are not constricted. \nso on excess of the two stimulants, the ventricle might fill two much and during pumping it out, the muscular valves, which are thinnner at ventricle, might burst or stop the heart

I was wondering myself.  So, when no one answered I decided to do some research.  I found several explanations that did not make sense.  But I did locate some credible sources.\n\nThe first reference gives technical information on encoding the magnetic strip.\n\nThe second provides confirmation that noise from scratches or defects in the magnetic strip induces spikes in the reader that can be misinterpreted as valid data.\n\nThe third provides an explanation in layman's terms that is consistent with the more technical explanations.  The following quote is from this source.\n\n"Let's just say that when you swipe the card through the reader, the magnetized particles in its stripe generate a signal with "ticks" in it at intervals that the machine is able to interpret as digital ones or zeros. A scratch or other defect in the magnetic stripe can cause a spike (i.e., brief fluctuation) in the signal that a too-sensitive reader will interpret as a tick, meaning that the encoded data will fail the parity check (the numbers won't add up right) and the card won't work. Wrapping the card in plastic increases the distance between the read head and the magnetic stripe, thus reducing the strength and crispness of the signal and smoothing out anomalous fluctuations. Behold, the card works."

How it works\n\nPolysporin* Scar Solution* uses clinically proven silicone sheet technology, the same technology used for years by plastic surgeons and burn centres, to help make old and new scars a more natural colour and reduce their size by mimicking the natural barrier function of normal, healthy skin.\n\ni used to market earlier , it really helps..

Define effective and long run.\n\nIt works for large numbers yes, but it is developed to work with actual numbers. When applying TSM well, you'll even beat a calculator. But in math you work with formulas en equations and the benifits from TSM will be marginal.

The product I take is liquid in form, with Green Tea and other antioxidants.  It works from the first few minutes after you take it.\n\nIf you are interested in looking into it, write me (wasdadd) at yahoo.

In diastolic dysfunction (impaired relaxation) it slows the heart rate, increasing filling time ultimately resulting in increased cardiac output.\n\nIn systolic dysfunction (impaired contraction) it is thought to work on decreasing the sustained sympathetic stimulation seen with left ventricular dysfunction which can cause the b receptors to down regulate.  It also decreases the risk of fatal arrythmia associated with sympathetic surges.  It decreases myocardial oxygen demand.  There is some decrease in contractility initially, however doses are usually titrated gradually and tolerated.  After months of treatment contractility can actually improve due to the reasons described above.\n\nAdditionally, people are usually not started when in florid heart failure.

Tons of information is available from Dave Palumbo's magazine 'Rx Muscle'.\n\nBut trust me.  They work, they work quick, and they work GREAT.
