You won’t notice me as I line up with the back of the pack at the local 5k this weekend. You might notice my son, tucked into his running stroller in his bright orange “I Know You Can Do it” shirt. You might even offer him a high five, which he will gladly return. But you won’t notice me. I am neither the fastest or the slowest. I am not running in a costume, or the finest and newest in running apparel. I am not the heaviest or the thinnest. I will never be on your leader board. You won’t hear my name at the awards ceremony. You will not notice me this weekend.

I was never a runner. A singer, a cheerleader, an actress, a math nerd, yes. But a runner? No. That was my sister. She played basketball, and she did it well. And in the off-season, she ran cross country and track to stay in shape. In the off season. Three miles a day, three or four days a week. Three miles? My God, I couldn’t imagine. Too much like work, as far as I was concerned.

I married young, when I was twenty three. My husband and I were desperately in love, happy and carefree. Three days after we returned from our honeymoon, I went to the doctor for a routine visit. I was a newlywed, relaxed and tan, and when the doctor began rattling off alphabet soup to her nurse, I didn’t think twice about it. CBC, T4, they meant nothing to me. I was the very definition of ten feet tall and bullet proof.

Six months later, after countless blood tests, uptake scans, ultrasounds, and biopsies, I underwent a partial thyroidectomy for a lump on my thyroid that almost certainly wasn’t cancer.

Only it was.

It was two different types of thyroid cancer, both aggressively attacking my lymph nodes, but fortunately very treatable. Two surgeries and a round of radiation later, I was on my way with a prescription for Synthroid and a clean bill of health. I told everyone I was fine. I thought I was fine. I was far from it.

Cancer changes you. My body had attacked me, so I attacked it back. I ate whatever I pleased, whenever I pleased. I was self destructive. I reveled in feeling poorly, paying my body back for what it had done to my spirit. Depression settled in, and the weight piled on. At the time, I didn’t realize how bad it was but looking back, I’m shocked I was able to keep from my family how very, very sad I was. After three long years and a very difficult pregnancy, I realized something had to change. I was sick and tired of the way I looked, sick and tired of the way I felt. Sick and tired of being sick and tired.

I easily talked myself out of doing anything rash, like joining a gym or changing my eating habits. But I did begin to walk. I strapped my son into his bulky stroller and walked around my neighborhood every day. I did it while my husband was at work; I didn’t want witnesses to my huffing and puffing. When I began having trouble getting out of bed because of my sore legs though, I had to let my husband in on my secret. He was immediately supportive, loading my closet with new running clothes and nudging me towards the door when I began talking myself out of my walks. A few weeks later, a shiny new running stroller arrived at our door. I laughed because running? Me? I don’t think so.

Slowly though, I did begin to run. At first it was just one lap, not even three quarters of a mile, around our neighborhood. Then two laps, then three. I can’t even remember who first suggested that I run a 5k, whether it was me (certainly not) or my husband or my sister, who began to run with me and take it in turns to push the stroller, but on June 23, 2007, I lined up to run my first 5k. I was nervous and uncertain and downright terrified. My sister stood beside me, prattling on so I wouldn’t have to talk.

We finished the race in 47 minutes. It hurt, and I was miserable, but as soon as I finished, I knew I’d run another.

And I did. I ran half a dozen 5ks, then decided to move up to a 10k. It was the best run of my life, and before I knew it, I had registered for a half marathon. On February 10, 2008, exactly three years after being declared cancer free, I finished the Mercedes-Benz half marathon in just over three hours. I finished with tears streaming down my face.

I started running to change my body. I kept running because it changed my soul.

My friend Angela is always telling me to take baby steps. I tend to rush into things without looking, expecting perfection of myself, setting myself up for failure. I finally took her advice and changed my life.

And somehow, when I wasn’t even looking, I became a runner.

How To Quit Smoking

July 12th, 2008

If your reading this document then I would assume that you are eager if not desperate to rid yourself of the addiction that has permeated probably almost every aspect of your life and may now also ultimately be affecting your health to the point you can no longer sustain your present lifestyle .

The author quit smoking in 1999 and did it without the aid of nicotine patches, gums, additives or any other chemical helper to try and ease the pain of the withdrawl symptoms.I have not had or touched a tobnacco product sime that time today’s date is May.06.2008 .

But I had to quit my health was suffering badly I was a the point one drag would send my lungs into an explosion of pain , I was truly stuck between addicton and needing to quit . I had several false starts too before I finally kicked the habit.It was an experience I am not going to forget any time soon , being stuck like a yo yo refraining one minute then scrambling for a puff the next. Before I finally made the reslove to do it for real I truly was on my last leg of health of which I could go no further with smoking.

Why we smoke!

Nicotine is classified as a tranquiliser however there are other chemicals in cigarettes that cause your body to produce adrenaline and that triggers the brain into believing that something exiting maybe dangerous is going to happen , like winning a lottery or meeting a movie star.
So the combination of tranquility and exitement that counterbalance each other actually produce exitement but in a euphoric sort of way. When you are feeling this exitement caused by the cigarettes it’s reinforcing the way that you want to feel, which is exited because you think something good is going to happen.
I have heard people say things like ” It calmes me down ” thats the tranquilising side .The there are the smoking triggers such as getting into your car or the phone rings, ask yourself why do you reach for a smoke at these particular times ?It’s because you want to feel that special kind of exitement and you want to ease the pain of say bad news if the phone call could be something bad.

We could go on and on about smoking triggers, chemical reacions, emotional wellbeing, ect ect but the bottom line is that we smoke because we get something we want from it! That’s the pure simple truth.

Now the Hard Part!

Before you even attempt to quit there are afew simple things you need to do before yo u start , this I learned the hard way so for you the ride might be a little bit easier.
First you need to have a clear understanding.

First resolve:

From the moment you take your last puff…. THATS IT ! No going back , no just one little puff here or there say on your b day or if a baby’s born . THATS IT , if your addiced and quitting smoking is going to be hard for you then understand and get it through your head once and for all , and tatoo it to the inside of your eye lids “THATS IT ” !

Second resolve:

Quitting smoking is going to be hell , if you are having real trouble and you want to do it right and not give in then be prepared to undestand and accept the fact that it’s going to be HARD HARD HARD ! No matter what anyone says the withdrawl symptoms are going to make you feel like ripping yourself out of your own skin and biting your tongue off ! You will soon discover how nasty and evil your “Good buddies ” [ nickname for smokes] truly are once you lay them to rest.I don’t know anyone who has been successful with patches and other helpers but my way is cold turkey and it is to this method I am referring .

Third resolve: There will be times in your life when the compulsion to have a smoke even afew years after you quit becomes so strong you simply cannot resist . This happened to me when I attended a Slayer rock concert . All I wanted to do was get as high and drunk and f ed up as I possibly could although I have never done hard drugs. But smoking was on the list for that night. If I could go back to that time I would not have taken the smoke. Rather I see it now as the warden that imprisons you instead of the gatekeeper that set’s you free !

Now for the good part !

You can think of quitting smoking as breaking the spine of your enemy .
Once you have broken it’s spine the physical and psychological hold it has over you greatly diminishes.

For me I guess it took about 7 days to break the spine of my cigarette addiction . For 7 days all I could think about was breaking down and getting another puff but I knew that it would lead to disaster because of my lung problems.So I was greatly stuck and needed a tremendous amount of willpower to hold out against the cravings .In the first 6 days I felt as if I was someone else , I was uncomfortable all the time , I had an awareness of my mouth which is really annoying , I had brain fog and had trouble concentrating because all I could think about was having a smoke . I guess I had anxiety because I knew that if I kept my promise about it being my last puff I would NeVER have another one as long as I lived literally it was all I could think about from dawn to dusk !

On the seventh day !

I got up as usual and my thoughts immediately turned to the days work ahead as I planned what I was going to do , I went to the shower turned on the tap started to wash and then it hit me ! ” My god I made it a whole ten minutes without not even the slightest inclination about having or wanting a cigarette . I knew I had broken the spine of my enemy at that point.Literally all the really bad withdrawl symptoms became only slight blemished as to what they had been , I drank and enjoyed my coffee and my lunch and also enjoyed having more energy , getting things done faster and the feeling of not having my lungs burning .All in all it was a really good day!

How I got through the cravings

Since I went cold turkey there was only one tool I used and it was a psychological one . Since my cravings and uncomfortable feelings were so bad they bordered on depression as well, I had to have a way of visualising myself rising out of this addictive hell .
I did it with a simple affirmation.

I would close my eyes, try to relax take a deep breath and focus to calm myself and then repeat to myself ” Beyond the hell of today lies a utopia of tomorrow.I know this utopia is going to be a far better life and what I feel right now will be banished from my being for good.I will be empowered to realise my dreams and live a life far greater than the one I have while imprisoned in this world of cigarette addiction.

As I read the affirmation to myself I visualised myself doing things i couldn’t possibly do while I smoked cuz my health wouldn’t allow it . i envisioned skiing and mountain climbing and playing soccer or any other kind of fantasy you like . It’s your world ! I envisioned myself being in goopd shape and more attractive to women and stuff , these are powerful motivators.

The cravings lost their hold for a while and when they came back I hit them harder with affirmation continually reinforcing the fantasy world I was determined to make a reality .

All I can say is that well … It Worked!

You really didn’t give up anything .

Now if you can say you don’t smoke anymore and say it with the confidence of knowing you don’t even flirt with them you can start exploring ways of recreating the exitement/ tranquilising feeling that you had exept this time without cigarettes. Eg Exercise : produces powerful endorphrins and a hot tub afterwards is pure magic .

How about turning out all the lights ordering your favorite pizza and then watching a super scary movie? Again no smoking but you will enjoy some cool and tingly emotions !

These are just a couple of examples . You can get as creative as you want.

One last thing …

After you quit smoking your body may react in some strange ways . It may recognise that your trying to improve your health and go on a campagne to liberate you from years of toxic builup in your organs and tissues, so if you end up feeling physically blah for a while after quitting then there is a good chance it’s toxins affecting you while they are being liberated from your body . But go see your doctor if you experience strange health problems of any kind. This article is not intended to be a representation of medical advice!

Remeber there truly is a utopia that lies beyond addictive behaviour.
You were born free and that is how you should remain !

Good Luck !

Polymerase chain reaction (PCR)

July 3rd, 2008

DNA is mixed with short (10–20 base) single-stranded oligonucleotide primers that are complementary
to the 5′ and 3′ ends of the sequence to be amplified. The mixture is heated to dissociate or “melt” all double-stranded DNA, and then cooled to permit the primers to anneal to their complementary sequences on the DNA to be amplified. Note that the 5′ primer will anneal to the “lower” strand, and the 3′ primer will anneal to the “upper” strand. A heat-resistant (thermostable) DNA polymerase (Taq polymerase, see text) was present in the original mixture, and it now synthesizes DNA by starting at the primers and using the strands to which the primers are annealed as a template. This results in the formation of two double-stranded DNA copies for every molecule of double-stranded DNA in the original mixture. The reaction is then heated to melt double-stranded DNA, cooled to allow reannealing, and the polymerase makes new double-stranded DNA again. There are now four double-stranded DNA copies for each original DNA molecule. This process can be repeated n times (usually 20–50) to result in 2” copies of double-stranded DNA.

NUCLEOTIDE SEQUENCING

July 3rd, 2008

The nucleotide sequence of a gene’s coding region encodes the amino acid sequence of its protein. This means that even in the absence of any knowledge about a gene’s protein, we can predict the structure of that protein given the nucleotide sequence of the gene. How can the nucleotide sequence of a gene be determined?

There are two methods used for sequencing DNA, the “chemical modification” method devised by Maxam and Gilbert,25 and the “enzymatic chain termination” method devised by Sanger and his colleagues.  Because of its ease and wider use, the chain termination method will be described here.
The chain termination method relies on properties of enzymes called “DNA polymerases” . These are enzymes that create new DNA polymers starting from individual nucleotides. However, in order for a DNA polymerase to work, it needs a “template” of single- stranded DNA on which to create the new polymer. DNA polymerase adds a new nucleotide to the 3′ end of a growing DNA chain, but the base of the new nucleotide must be able to base-pair (i.e., be complementary) to the base on the template over which the polymerase
is positioned. After the addition of that nucleotide, the polymerase moves to the next nucleotide on the template, and adds a new nucleotide to the 3′ end of the growing chain. Again, the new nucleotide must be complementary to the next base in the template.

When the process is completed, the DNA polymerase will have made a new DNA chain whose nucleotide sequence is completely complementary to the template DNA.
Nucleotide sequencing is based on the observation that when DNA polymerase adds a synthetic abnormal nucleotide to a growing chain, the polymerization stops. The synthetic “terminating” nucleotides used most commonly are dideoxynucleotides that have no alcohol substitutions on the 3′ carbon of their deoxyribose groups, and thus cannot be joined by a phosphate bridge to the next nucleotide . For example, in the presence of dideoxy-ATP (ddATP), chain termination will occur wherever an A appears in the new DNA sequence  These reactions are performed in vitro in a test tube, where millions of new DNA molecules are being made at once. If normal deoxy-ATP is mixed in the proper proportion with dideoxy-ATP, only a few of these molecules will terminate at each T in the template. This will generate a series of new DNA polymers,
each one stretching from the beginning of the chain to the position of an A . If the newly formed DNA is
radiolabeled, and the products of this reaction are separated electrophoretically in a polyacrylamide gel (see below), a ladder of radioactive bands will be generated. Each step of the ladder is a fragment of DNA that stretches from the start of the new polymer to the position of an A. Four separate reactions are performed using each of the four dideoxynucleotides. Each reaction is run in an adjacent lane on a polyacrylamide gel so that the nucleotide sequence can be read directly from the gel by reading up the steps of each ladder.
A specific application of DNA sequencing in cancer research has been the analysis of mutated sequences in the tumor suppressor gene p53.

The hallmark of tumor suppressor gene involvement in cancer is loss of function of these genes. While loss of function can occur by deletion of all or part of the gene, the same result can be achieved if the gene
undergoes a mutation that inactivates its protein. Thus, in many types of cancers that have retained a p53 allele, as determined by Southern blotting, DNA sequencing has shown that the remaining allele has often
undergone a single nucleotide, or “point,” mutation.27,28

RAPID TECHNIQUES FOR DETECTING MUTATIONS

Powerful as DNA sequencing may be, it is usually too cumbersome to be used as a screening tool for the identification of single mutations in patient DNA samples. A variety of clever techniques have been developed, which rapidly reveal single-base mutations without resorting to DNA sequencing.29 One is denaturing-gradient gel electrophoresis (DGGE), which depends on the fact that double-stranded DNA molecules “melt” or denature into single strands at different temperatures or chemical conditions, depending on their specific sequences.

For example, one can construct electrophoresis gels that contain a gradient of increasing concentrations of denaturants, such as urea or formamide, and if DNA is electrophoresed through such a gel, it will stop
migrating at the position at which it has denatured. If two DNA fragofments of identical length differ in their sequences at only one base pair, the concentration of denaturant at which the two fragments melt will
be slightly different. Thus, electrophoresis of these two DNA fragments through a gradient of denaturant will distinguish them by the positions at which the two fragments stop migrating. One could begin with fragments isolated by polymerase chain reaction (PCR) (see below), making this a convenient way to screen for the presence of common mutations using only a small amount of patient material.

Another simpler technique is single-stranded conformation polymorphism (SSCP), which relies on the differences in mobility between single-stranded DNA molecules on the basis of their secondary structures
in nondenaturing gels. Single-stranded DNA molecules can fold back on themselves due to intrastrand base-pairing and form unique shapes called “secondary structure.” Alteration of one base in a short
DNA molecule could, therefore, have profound effects on secondary structure by altering the pattern of intrastrand base-pairing. DNA molecules of identical length but different secondary structure will migrate at different rates in nondenaturing electrophoretic gels. Thus, DNA fragments can be isolated or synthesized by performing PCR on patient DNA samples, they can then be denatured, and individual strands allowed to reanneal to themselves rather than to their complementary strands. The products can be separated by nondenaturing electrophoresis, and fragments containing single base pair mutations can be identified by their anomalous migration. Although technically simpler than DGGE, which can detect nearly 100% of single base pair mutations, SSCP can only detect about 80% of such mutations.

POLYMERASE CHAIN REACTION

To detect gene sequences by Southern blotting, at least 1 to 2 μg of genomic DNA is required. This translates into milligram quantities of tissue that must be used fresh or freshly frozen. By amplifying specific fragments of DNA, the PCR lowers the theoretical limit of detectable DNA sequences in a sample to
a single molecule of DNA. With some advance knowledge of thenucleotide sequences in the DNA to be detected, microscopically small amounts of tissue, even a single cell, contains enough DNA to be
amplified, and the amplified DNA can be easily analyzed. Even fixed tissue in paraffin blocks or on slides can yield sufficient DNA for analysis using PCR.

The concepts underlying PCR are diagrammed in Figure 1.9. Two short single-stranded DNA fragments, called primers, have sequences complementary to those that flank the stretch of DNA to be amplified.
They are added to the target DNA, the mixture is heated to dissociate the paired double strands of target DNA, and then the temperature is lowered to permit hybridization, or annealing, of the primers to their
complementary sequences on the target DNA. A DNA polymerase enzyme is added to the mixture which will add nucleotides to the 3′ end of the primers using the target DNA as a sequence template. This step generates one copy of each of the strands of one target DNA molecule. The mixture is heated again to dissociate the strands, then cooled to allow more primers to anneal to the target sequences on both
the original and new pieces of DNA. DNA polymerase is added again and now generates four copies of the target sequences. These steps are repeated, resulting in a geometrically increasing amount of target
DNA, that is, a chain reaction.

When it was first devised, this technique used a DNA polymerase from E. coli, which is inactivated by heating, so that fresh enzyme had to be added at every step. With the discovery and cloning of
the DNA polymerase from the thermophilic bacterium, T. aquaticus (the Taq polymerase), which retains activity after being heated to 95°C, heating and cooling steps could be carried out on the same mixture
without adding new enzyme.35 This allowed the procedure to be automated. There are now automated thermal cyclers in every molecular biology laboratory, and in many clinical laboratories, that will take
PCR mixtures through 20 to 50 cycles, producing large amounts of synthetic DNA for subsequent analysis.

PULSED-FIELD GEL ELECTROPHORESIS

July 3rd, 2008

One application for Southern blotting is the direct demonstration of physical linkage between two genes. If two different gene probes were to hybridize to the same restriction fragment in a Southern blot, this would prove that the loci of the two genes were closely linked. Unfortunately, eukaryotic genetic linkages ordinarily extend over millions of bases (megabases) of DNA, and the largest DNA fragments that can be resolved by conventional agarose gel electrophoresis are less than 100 thousand bases (100 kilobases). The reason for this limitation is the tendency for all DNA molecules above a certain size to become oriented with their
long axes parallel to the electric field.

Easy Steps to Prevent Mesothelioma

June 1st, 2008

Mesothelioma is a rare cancer that attacks the body’s mesothelial cells around the organs. The mesothelium provides a protective membranous lining for the internal organs and allows moving organs (i.e. the heart and the lungs) to glide easily against adjacent structures. The names of the three regions of mesothelial cells that provide protective coating are 1) pleura, the sac which surrounds the lungs; 2) peritoneum, the lining which protects the abdominal cavity; and 3) pericardium, the sac which surrounds the heart. Three different types of mesothelioma cancer attack these three different regions.

Pleural mesothelioma: A type of lung cancer which attacks the pleura surrounding the lungs, this is the most common type of mesothelioma, affecting approximately two-thirds of all mesothelioma patients. Symptoms include horseness, fever, blood in sputum, swollen arms and face, coughing, loss of weight, difficulty breathing, chest pain, weak muscles, and reduced tactile sensitivity.

Peritoneal mesothelioma: A cancer of the abdomen which attacks the peritoneum lining the abdominal cavity. This affects approximately one-third of all mesothelioma patients. Symptoms include abdominal bloating, impaired bowl function, fever, swollen feet, and nausea.

Pericardial mesothelioma: This form of mesothelioma which attacks the pericardium surrounding the heart is extremely rare. Symptoms include chest pain, dyspnea, cough, and palpitations.
Mesothelioma has been linked to asbestos exposure. Asbestos is a type of building material used in thermal insulation products and ceiling tiles. In the United States, asbestos usage peaked during the 1950s - 1970s. During the late 1960s, concerns over the health consequences of asbestos exposure began to arise, thereby decreasing the amount of asbestos manufactured in next two decades. By the 1980s, a new industry of asbestos abatement began to flourish. But according to the United States Environmental Protection Agency (EPA), as many as 733,000 schools and public buildings still contain asbestos.

Small asbestos fibers that enter the air do not evaporate and can remain suspended in the air for a long time. These fibers, when breathed into the body, are toxic. There are three types of asbestos exposure.
Occupational asbestos exposure: People working in factories that manufacure asbestos are likely to have a high exposure to asbestos and are most at risk of developing asbestosis or mesothelioma.
Paraoccupational asbestos exposure: Family members of workers exposed to asbestos in the workplace are susceptible to exposure from asbestos dust brought home by the worker on his clothes or skin.
Neighborhood asbestos exposure: Those who live in the vicinity of an asbestos manufacturing plant are also at risk.
Mesothelioma is still a relatively rare form of cancer. There are an estimated 2,000 - 3,000 new cases per year in the United States. Approximately 7-13 per one million male patients with a history of asbestos exposure contract mesothelioma. Diagnosis usually occurs 20-40 years after initial exposure to asbestos.

Choosing a Mesothelioma Doctor

June 1st, 2008

Mesothelioma Cancer is considered, within the medical profession, to be a serious illness. Mesothelioma Doctors are now available to those who are sufferers of Mesothelioma Cancer.

Mesothelioma Doctors are well educated in the cause of Mesothelioma Cancer, diagnosis of Mesothelioma Cancer, the affects of Mesothelioma Cancer and the available treatment for Mesothelioma Cancer.

Therefore, when choosing a Mesothelioma Doctor, ensure that they have expertise, or quality experience in the area of Mesothelioma Cancer. This can be achieved through your general GP’s general enquiries on your behalf, or through conducting your own research.

You might even consider making enquiries with the American Cancer Society, who hold a variety of information about different types of Cancer and where to seek help. When seeking help it is best to research all your available options and then choose the best one for you.

Some of the important information that you might need to tell your Mesothelioma Doctor include, what types of symptoms you are experiencing, how long ago since you were exposure to an Asbestos related substance and for how long where you exposed to the Asbestos related substance.

After you receive and initial consultation from your Mesothelioma Doctor, you may be required to undergo either a Chest CT scan, or a biopsy, depending on which type of Mesothelioma Cancer your Mesothelioma Doctor considers that you have.

Essentially, there are three possible types of Mesothelioma Cancer that you could have. These include, Pleural (Lungs) Mesothelioma Cancer, Peritoneal (abdominal) and Pericardial (heart).

Once your Mesothelioma Cancer doctor has made a definitive diagnosis, he/she will then be able to tell you which type of Mesothelioma Cancer you have, at what stage the Mesothelioma Cancer is, whether it has spread to surrounding organs, or whether it is contained within the original area of the diseases initiation.

Your Mesothelioma doctor will then discuss your treatment options in relation to the type of Mesothelioma Cancer that you have and what stage the Cancer is at. Your Mesothelioma Doctor should explain these options in detail, including any side affects and the recovery period.

Your Mesothelioma Doctor should also explain to you what the results of not undergoing these recommended treatment options could be. Essentially, your Mesothelioma Doctor should give you a detailed explanation of your entire prognosis.

Your prognosis should include details regarding any risks that you may be subjected to, the chances of the Cancer reoccurring following treatment and how long you are expected to survive once treatment has been implemented.

Keep in mind that through ongoing research into Mesothelioma Cancer, treatments are becoming more effective and patients diagnosed with Mesothelioma Cancer, who undergo treatment, are surviving for longer periods of time.
