General Articles, - The protein that reveals the heart’s ability to repair itself: Thymosin Beta-4- visit-http://aydnajimudeen.blogspot.com

Beyond all the miraculous systems in the body, the heart by itself
is one of the finest examples of flawless creation. No similar
artificial mechanism that "can keep someone alive" has thus far been
built, despite all the recent scientific advances. With the cells
that comprise it, its special valve systems and the manner in which
the opening and closing of these valves is regulated, the heart is
an organ with exceptionally complex and special systems. No other
organ can do anything like the work it performs.

· How can the heart repair itself following a heart attack?
· What role does the thymosin beta-4 (TB4) molecule play in the
heart's self-repair?
Although it is only 22 days since its creation, a small collection
of cells on the left side of the fetus begins to move. This
collection of cells will never stop now, not for a very long time.
It will never tire. It will beat approximately 70 times per minute,
some 35 million times per year, and around two trillion times over
the course of an average life span. It will pump some 227 million
liters of blood over the course of a lifetime. It will tirelessly
feed all the organs of the body through the network of blood
vessels . The heart functions perfectly in every body because Allah
so chooses, and everything it does is under our Lord's control at
every moment. Allah exhibits His artistry of detail in the human
body and reveals this in a verse:
" Allah brought you out of your mothers' wombs knowing nothing at
all, and gave you hearing, sight and hearts so that perhaps you
would show thanks." (Surat an-Nahl, 78)
This organ, the foundation of life, also uses blood to nourish
itself. However, in order to remind people of their weakness, our
Lord may sometimes cause the vessels that feed the heart to narrow,
using such natural causes as cholesterol (blood fats), other fats,
calcium and combinations of other substances. This then leads to
impaired circulation in the blood vessels (coronary arteries) that
supply the heart, finally resulting in a heart defect. When the
narrowing of the vessels turns into complete blockage over the
course of time, the result is severe chest pain and a heart attack.
This generally proves fatal, though some victims do survive. But
their hearts still suffer damage from the attack.
Recent studies have once again shown Almighty Allah's love for and
mercy on His servants. Because a protein that the heart produces
during the developmental stage in children enables the damaged
heart to be repaired and increases the vessels supplying it.
The Healing Power of the Heart: Thymosin Beta-4
During a heart attack, heart cells die when the flow of blood to the
heart is suddenly cut off, resulting in irreparable damage. This
damage persists in the form of a decreased quality of life in the
patient's later life.
Until recently it used to be thought that, unlike other organs, the
heart had no ability to repair itself. Today, however, we know that
this damage can be put right by the body. The protein thymosin beta-4
(TB4), which plays a key role in the development of the heart in
children, activates stem cells that are lie dormant in the adult
heart. These tiny proteins, known as thymosin, which comes in two
forms in living tissue, α 1 and β 4, possess the ability to
reprogram cells in the body. The protein is today administered in
the form of a drug, and sends the stem cells a code regarding the
repair of the heart. The heart thus heals itself without the need
for other treatment. Administered in pharmaceutical form, this
protein improves heart performance by up to 25% by causing stem
cells to turn into heart and artery cells. It repairs the damaged
heart cells, increases the arteries supplying the heart and permits
the muscles to repair themselves.
Allah, the Creator of All, Is Most Great
Events in our body that we are unaware of, and whose existence we
have usually never even heard of, take place inside us with the
greatest regularity. Our heartbeat, essential for our survival, is
not something we initiate or maintain of our own will. Our heart is
one of the organs miraculously created by our Lord. This organ
begins beating as a collection of cells when a person is still in his
mother's womb, and continues to flawlessly discharge its duties
until the end of that person's life.
Research in recent years has revealed that in the event of a defect
arising in this immaculately functioning organ, various proteins go
into action to repair it. However, proteins themselves possess no
such medical knowledge with which to identify defects developing in
the heart, and lack the consciousness to save a person's life by
taking such precautions. Yet they are present in everyone's body
and ready to serve the same function. A protein with such superior
properties is neither the product of human intelligence nor of any
supposed evolutionary process. It was created by Allah, He who
bestows order, glory and perfection on all He creates. Allah is He
Who meets the needs of all created things ( Kafi ), He Who enfolds
them ( Muhit ) and Who is mighty enough to do all that He wishes, in
the manner He wishes ( Kadir ). He is the only One to be thanked and
praised ( Hamid ). He is the One who creates without previous
models ( Bedi ). This is revealed in the following verse:
"the Originator of the heavens and earth. When He decides on
something, He just says to it, 'Be!' and it is." (Surat al-Baqara,
117)
The heart is made up of special muscles that never tire. If your
heart muscles were to tire in doing things that cause you fatigue,
then you could never do such routine day-to-day activities as
cleaning, sport, climbing up stairs and the like. You would be
exhausted before you even began. But apart from exceptional
diseases, this never happens. Because Allah manifests His infinite
mercy on His servants by bestowing tirelessness on the muscles of
the heart. There is no doubt that this is one of the matchless
works of our Lord, who knows all things down to the finest detail
and Who manifests His omniscience in every detail. The omniscience
of Allah is revealed in the following verse:
"... My Lord encompasses all things in His knowledge so will you
not pay heed?" (Surat al-An'am, 80)
There is a highly systematic mechanism in the heart. That mechanism is
essential for human life. Otherwise, a single flaw arising in the
system could spell the end of the life of the person concerned. The
most important of the heart's mechanisms is the pumps on its right and
left. There are also auricles and ventricles on both sides of the
heart. The small pumps on either side are the auricles, while the
ventricles constitute the large pumps. The left side of the heart is
occupied with clean blood. It is the task of the left auricle and
ventricle to ensure that incoming blood reaches the organs and
tissues. The right side of the heart is occupied with used (dirty)
blood. The right auricle and ventricle send the blood to the lungs for
cleaning.
The Heart Is An Immaculate Organ Created By Almighty Allah
It Pumps Blood with Ease: The heart is a piece of flesh the size of
a fist composed of water, fats and proteins. This piece of flesh
possesses a more perfect and complex system than the most advanced
technological pump that all the experts in the world could produce
using their computers. This matchless piece of flesh is strong
enough to cause blood to spout up to three meters in the air.
It Identifies Oxygen Requirements: The heart pumps as much blood as
it calculates the body needs. This wondrous organ pumps just four
to six liters of blood per minute when the body is at rest. That
is enough for the person at that time as the cells in the body do
not require that much oxygen just then. But someone doing
strenuous exercise needs more oxygen. Oxygen needs to be
transmitted to the cells more quickly. The heart immediately
identifies this need and begins beating faster. The amount of blood
pumped by the heart increases by four to seven times during
exercise.
It Supports Tiring Muscles: The heart never stops working, but
sometimes it works even harder than usual. When one runs, the amount
of blood pumped by the heart can rise to 2,270 liters an hour. It
can raise its work rate from 70 beats per minute to 180 per minute
in order to provide the oxygen our tiring muscles need. It can
increase the amount of blood supplied to the tissues five-fold. When
our other muscles engage in a tiring activity, the heart
accelerates to support them.
It Coordinates the Auricles and Ventricles: The system in the heart
has perfect timing. That is the result of co-ordination and
communication among the cells that comprise the heart. The
noteworthy thing here, of course, is the "intelligence" in the cells
that act under the inspiration of Allah. The cells that make up the
heart send a current to the other side of the heart at a speed of
some 60 centimeters per second. The signal is sent from a region
known as the S.A. node. The cells that make up the S.A. node produce
the signal in just 1/14 of a second. There are cells that produce a
second current here, known as the A.V. node. The current sets the
two auricles into motion as it passes and causes them to contract in
order to collect blood. When the electric current, that is still
moving, reaches the ventricular muscles, special fibrous cells in
the muscle tissue between the right auricle and the right ventricle
halt it. This causes a delay in the current reaching the ventricle.
The speed of the current falls to 20 centimeters per second and it
begins being transmitted in 1/16 of a second. This delay is
exceedingly important. Because of it, the auricles fill with blood
before the ventricles contract, and are thus able to prepare
themselves to pump blood. This is the secret of the synchronized
action of the heart.
