“Effects of radiation on living tissues”

Radiation may come from either an external source like fallout from bombs, melt down from nuclear power plant melt downs  given off into the environment both air, water and food, x-ray machine, or an internal source, such as an injected radioisotope.

How does radiation effect living tissues?
The impact of radiation on living tissue is complicated by the type of radiation and the variety of tissues.

What effect can ionizing radiation have on the cells’ chemical bonds?
The functions of living tissue are carried out by molecules, that is, combinations of different types of atoms united by chemical bonds. Some of these molecules can be quite large. The proper functioning of these molecules depends upon their composition and also their structure (shape). Altering chemical bonds may change composition or structure.

Ionizing radiation is powerful enough disrupt chemical bonding. For example, a typical ionization releases six to seven times the energy needed to break the chemical bond between two carbon atoms.[91] This ability to disrupt chemical bonds means that ionizing radiation focuses its impact in a very small but crucial area, a bit like a karate master focusing energy to break a brick. The same amount of raw energy, distributed more broadly in nonionizing form, would have much less effect. For example, the amount of energy in a lethal dose of ionizing radiation is roughly equal to the amount of thermal energy in a single sip of hot coffee.[92] The crucial difference is that the coffee’s energy is broadly distributed in the form of nonionizing heat, while the radiation’s energy is concentrated in a form that can ionize.

What is DNA?
Of all the molecules in the body, the most crucial is DNA (deoxyribose nucleic acid), the fundamental blueprint for all of the body’s structures. The DNA blueprint is encoded in each cell as a long sequence of small molecules, linked together into a chain, much like the letters in a telegram. DNA molecules are enormously long chains of atoms wound around proteins and packed into structures called chromosomes within the cell nucleus. Only a small part of this DNA needs to be read at any one time to build a specific molecule. Each cell is continually reading various parts of its own DNA as it constructs fresh molecules to perform a variety of tasks.

What effect can ionizing radiation have on DNA?
Ionizing radiation, by definition, “ionizes,” that is, it pushes an electron out of its orbit around an atomic nucleus, causing the formation of electrical charges on atoms or molecules. If this electron comes from the DNA itself or from a neighboring molecule and directly strikes and disrupts the DNA molecule, the effect is called direct action. This initial ionization takes place very quickly, in about 0.000000000000001 of a second. However, today it is estimated that about two-thirds of the damage caused by x rays is due to indirect action. This occurs when the liberated electron does not directly strike the DNA, but instead strikes an ordinary water molecule. This ionizes the water molecule, eventually producing what is known as a free radical.

A free radical reacts very strongly with other molecules as it seeks to restore a stable configuration of electrons. A free radical may drift about up to 10,000,000,000 times longer than the time needed for the initial ionization (this is still a very short time, about 0.00001 of a second), increasing the chance of it disrupting the crucial DNA molecule. This also increases the possibility that other substances could be introduced that would neutralize free radicals before they do damage.
What immediate effects can ionizing radiation have on living cells?
All of these collisions and ionizations take place very quickly, in less than a second. It takes much longer for the biological effects to become apparent. If the damage is sufficient to kill the cell, the effect may become noticeable in hours or days. Cell “death” can be of two types. First, the cell may no longer perform its function due to internal ionization; or “reproductive death” (mitotic inhibition) may occur when a cell can no longer reproduce, but still performs its other functions.
Death may also result if cell reproduction ceases in parts of the body where cells are continuously being replaced at a high rate (such as the blood cell-forming tissues and the lining of the intestinal tract).

What long-term effects can radiation have?
The effect of the radiation may not be to kill the cell, but to alter its DNA code in a way that leaves the cell alive but with an error in the DNA blueprint. The effect of this mutation will depend on the nature of the error and when it is read. Since this is a random process, such effects are now called stochastic.[100] Two important stochastic effects of radiation are cancer, which results from mutations in nongerm cells (termed somatic cells), and heritable changes, which result from mutations in germ cells (eggs and sperm).

How can ionizing radiation cause cancer?
Cancer is can be produced if radiation does not kill the cell but creates an error in the DNA blueprint. Different cells have different sensitivities to radiation thus some take longer to show its effects like bone marrow is more sensitive than skin cells to radiation-induced cancer.  If the cell’s DNA mutates it can lose control of cell division, and begins dividing uncontrollably which produces the phenomena known as cancer. This effect might not appear for many years.
Cancers induced by radiation do not differ from cancers due to other causes, so there is no simple way to measure the rate of cancer induced by radiation.

Because the cancers can occur anytime in the exposed person’s lifetime,
How can ionizing radiation produce genetic mutations?
The risk of genetic mutation is expressed in terms of the doubling dose: the amount of radiation that would cause additional mutations equal in number to those that already occur naturally from all causes, thereby doubling the naturally occurring rate of mutation.
Well, on the one hand radiation can cause genetic mutation (cell death or cancer)… it can cause illness due to mutated proteins and whatnot that cause cellular function and processes to become messed up (radiation sickness). That is radiation, by itself. Radioactive material gives off radiation. If consumed or ingested, the source of radiation would be inside the body, providing a continuous dose.

Most radioactive materials are poisonous by its very chemical nature… like uranium, cesium, which is a heavy metal… and is poisonous regardless of its isotopic properties.

And chemical isotope that has one chemical property can be consumed and utilized by the body, naturally… like the formation of cell membranes or calcium for bones. If those chemicals themselves were radioactive then when they decay, they will convert to alternative chemicals. The radiation or material itself is irrelevant in this case, but the problem arises in the fact that essential components of the body are no longer built using the proper materials.

“Sleep it off, not by the TV”

The effects of Sleep loss on weight

10 overweight men and women  were put on a low calorie diet.

1/2 the group sleep for only 5 1/2 hours per night

!/2 slept 8 1/2 hours per night

After 3 months the groups switched the number of hours they were allowed to sleep

Results the effects of sleep deprivation on human body

  • no effect on weight lost
  • all lost 55 per cent less fat
  • 60 per cent more lean body ( mainly muscle) mass
  • increase in appetite due to increase in  hormone ghrelin
  • lower metabolic rate
  • increase tendency to gain weight or be obese

Both hormones leptin and ghrelin influence appetite. When you have sleepless night do you often feel that you cannot get enough food to satisfy your hunger the next day?no matter what you ate you never felt full or satisfied?

Sleep and sleep disruption do remarkable things to the body and some weight fluctuation can be attributed to the changes in the hormones leptin and ghrelin caused by stress.

Sleep in a quiet dark room and try to get 8 hours of solid uninterrupted sleep.  Good dreaming!

“Beware of kids loving tooth paste !”

Beware of young children loving tooth paste too much. Seems if a young child eats or drinks and then swallows too much fluoride, the fluoride, it can damage the natural coloration of their teeth permanently. Their teeth can be damaged mildly as in the image below or severely as in the bottom.

Dental fluorosis is a health condition caused by a child receiving too much fluoride during tooth development and nutrition. The critical period of exposure is between 1 and 4 years old; children over age 8 are not at risk. In its mild form, which is the most common, fluorosis appears as tiny white streaks or specks that are often unnoticeable. In its severest form, which is also called mottling of dental enamel, it is characterized by black and brown stains, as well as cracking and pitting of the teeth.
How does fluoride stain or pit the teeth?

Dental fluorosis occurs by ingesting too much fluoride, either from the fluoride in the water supply, naturally occurring or added to it; or from fluoride toothpaste or other sources. It damages teeth while they are developing in children between the ages of 3 months to 8 years, from the overexposure to fluoride.
How are teeth damaged by fluorosis?

Teeth are generally composed of minerals/calcium compounds, calcium phosphate hydroxyapatite and carbonated hydroxyapatite; when fluoride is present, some fluorapatite is formed. When excessive fluoride is present, white spots, brown stains or pitting or mottling of enamel will occur. Once the tooth has come through gums into the oral cavity, fluorapatite is beneficial; it is more resistant to dissolution by acids (demineralization). Although it is usually the permanent (adult) teeth which are affected, occasionally the primary (baby) teeth may be involved.

The organic portion of enamel does not contain collagen, as dentin and bone does. Instead, it has two unique classes of proteins called amelogenins and enamelins . The role of these proteins is uncertain but thought to be needed for the development of enamel as a framework support and other mechanisms.

Talk to your pediatric dentist or water treatment facility to tell you how much fluoride is in your local drinking water. If you drink well water or bottled water, your pediatric dentist can assist you in getting an analysis of its fluoride content. After you know how much fluoride your child receives, you and your pediatric dentist can decide together whether your child needs a fluoride supplement.

Caution:

  • Monitor your child when it is tooth brushing time:
  • If you are using a fluoridated toothpaste use a pea-sized amount on the brush is plenty for fluoride protection.
  • Teach your child to spit out the toothpaste, not swallow it, after brushing.

“Scientists unlock chocolate genes”

Don’t mess with Mother Nature
Researchers have found the genes that code for the production of the cocoa butter in Theobroma cacao, needed to make sweets, pharmaceuticals and cosmetics.
Studying the genes of Mother Nature’s finest crop cacao, researchers are finding ways to make the best chocolate in the world “better”. Better means, increased disease resistance and increased profitability to the grower.

Researchers have found genes that code for the production of cocoa butter, a substance highly prized in chocolate making, confectionery, pharmaceuticals and cosmetics. Most cocoa beans are already about 50 percent fat, but these 84 genes control not only the amounts fat produced, but quality of the cocoa butter.  Altering these genes might produce chocolate with better flavors, aromas and even “healthier” chocolate by influencing the production of flavonoids, natural antioxidants and terpenoids, hormones and pigments.
The team sequenced the DNA of a variety of Theobroma cacao, considered to produce the world’s finest chocolate. The Maya domesticated this variety of Theobroma cacao, Criollo, about 3,000 years ago in Central America, and it is one of the oldest domesticated tree crops. Today, many growers prefer to grow hybrid cacao trees that produce chocolate of lower quality but are more resistant to disease.
“Fine cocoa production is estimated to be less than 5 percent of the world cocoa production because of low productivity and disease susceptibility,” said Guiltinan, professor of plant molecular biology.
The researchers report in the current issue of Nature Genetics “consumers have shown an increased interest for high-quality chocolate made with cocoa of good quality and for dark chocolate, containing a higher percentage of cocoa, while also taking into account environmental and ethical criteria for cocoa production.”

“What’s swinging in your family tree?”

– M.Wolken editor of CMANews
When I went in the early 90s to a family reunion for my mother family I took time to observe what was swinging from my family’s health tree and the decade of life these  various health imbalances began to show. It was fasinating glimpse into the my possible health future.
My training in natural medicines especially Homeopathy has taught me to look at each of life’s challenges from a different perspective. Our response to each health and or emotional crisis has come to be from our cumulative training from those people and the environment both inside our body as well as those stresses of living our life has brought us.

To assist a person  find peace and wellness a practitioner must learn as much about the entire personal and familial history  as possible. Nothing in health or dis-ease happens in isolation.

Family health history a powerful, underused tool in modern medicine today.
In integrated medical practice like homeopathy, ayurvedic, oriental, and naturopathic medicines, the family history has always been seen as needed. We were taught the better the initial history the better the evaluation, the better insight, the better individualized care and the more positive the healing.

In Homeopathy and Oriental medicine add another aspect to the history and patient profile, learning how to observe how a person, how they move, presents themselves, shake hands, the health and coloring of their tongue and their emotional history are the vital components of the patient history.

These wholistic aspects to patient care are so often ignored or missed in the current “managed care system of seeing a person every 3 to 5 minutes, reminding them to focus only on what is bothering them the most and running on to the next person before the patient has gotten acquainted with the professional.
A recent  Cleveland Clinic study compared using a good oral family history to using simply the lab results from an online genomic testing services that analyze DNA glitches and predict people’s predisposition to various diseases to uncovered who might be at an increased risk of cancer.  Not surprisingly , a good family history taken by an office assistant from relatives accompanying the patient was found to be a better predictor.
All it costs is a little time questioning your relatives, yet good family health trees are rare. A government survey estimated less than a third of families have one – and time-crunched doctors seldom push their patients to remedy that.

*Encourage each family to write down as much as they can remember about the conditions their parents and elderly had, how they died and from what. Knowing both sides of your family tree are vital. A study of 2,500 women found that women not only know less about the health of their paternal relatives, they tend to dismiss the threat of breast cancer if it’s on Dad’s side.
“It’s a risk no matter what,” says Dr. Wendy Rubinstein of Chicago’s North Shore University Health System.

Dr. Charis Eng, a cancer geneticist at the Cleveland Clinic’s Genomic Medicine Institute believes that  “It’s the best-kept secret in health care.”

How to start your family health history.

The U.S. Surgeon General operates a free website – https://familyhistory.hhs.gov – that helps people create a family health history and share it electronically with relatives and their doctor.

“Will a laptop fry your parts?”

Sitting with a computer on your lap and the cell phone in your pocket on your hip or over your heart may effect your health and your ability to reproduce.
When the temperature in your upper leg area rises it may effect the quality, viability and numbers of sperm.of your nether regions.
In the journal Fertility and Sterility, short of putting your laptop on a desk, researchers found no way to protect the sexual organs..
The researchers hooked thermometers to the scrotums of 29 young men who were balancing a laptop on their knees. They found that even with a lap pad under the computer, the men’s scrotums overheated quickly. After one hour, when a laptop is held on your knees, sitting still with your legs closed. men’s testicle temperature had risen by up to 2.5 C.
A lap pad kept the computer cool and also made sure less heat was transmitted to the skin. But it didn’t do much to cool the testicles, and might give “a false sense of security,” according to Dr. Yefim Sheynkin, a urologist at the State University of New York at Stony Brook, who led the new study.
“Within 10 or 15 minutes their scrotal temperature is already above what we consider safe, but they don’t feel it,” he added. Under normal circumstances, the testicles’ position outside of the body makes sure they stay a few degrees cooler than the inside of the body, which is necessary for sperm production.  The body is designed to protect  the testicles’ position outside of the body to sure they stay a few degrees cooler than the inside of the body, which is necessary for sperm production.
Earlier research has shown that warming the scrotum more than one degree Celsius (1.8 degrees Fahrenheit) is enough to damage sperm.
According to the American Urological Association, nearly one in six couples in the US have trouble conceiving a baby, and about half the time the man is at the root of the problem.
Many factors influence reproductive health including genetics, lifestyle, nutrition, drug use and this up and coming factor heat and radiation effects from cell phones and cell phone towers.

Health Hazard
Using computers, cell phone or living too close to cell phone towers can increase damage to living cells, increase sleep problems and malignant tumors and ADD and ADHD symptoms,  fatique and decrease overall well being.

The solution is protection, healthy diet and placing cell phone towers at a safe distance from communities they are serving.

"Remyelination of the spinal cord after injury may be a step closer"

Brain and spinal cord injuries may soon have a new treatment process that is natural and based on the individual’s own stem cells. Oligodendrocyte, precursor cells (OPCs), are  a type of cell found in the brain and nervous system that forms the coating around the nerve cells. These cells are formed during embryo formation in the ventricular zone of the neural tube (embryonic spinal cord), and the cells migrate outwards along the circumference of the tube, and then along its length. During this migration, OPCs actively seek axons around which they can wrap

their processes once they have differentiated into oligodendrocytes. Myelination, the process by which oligodendrocytes wrap their processes around nerve fibers, begins towards the end of embryonic development, and continues post-natally coating around the nerve cells.

These cells are formed during embryo formation in the ventricular zone of the neural tube (embryonic spinal cord), and the cells migrate outwards along the circumference of the tube, and then along its length. During this migration, OPCs actively seek axons around which they can wrap their processes once they have differentiated into oligodendrocytes. Myelination, the process by which oligodendrocytes wrap their processes around nerve fibers, begins towards the end of embryonic development, and continues postnatally.


Throughout their migration, these cells extend and retract filopodia-like processes to obtain cues from their surroundings. Upon coming into contact with neighboring OPCs. These hair or cilia like projections are withdrawn and then extended in the opposite direction. This seems to be a mutual repulsion mechanism which ensures that OPCs are evenly distributed along the length of the axons they will myelinate (coat). An axon is a long, slender extension of a nerve cell, or neuron, that conducts electrical impulses away from the neuron’s cell body

Oligodendrocyte precursor cells (OPCs) comprise 5% of the cells in the adult brain, where they are the most proliferative cell present. They can generate both neurons and glial cells, making them an important stem cell population in the adult brain.
The bottom line is that this animal model with the injection of  hESC-OPCs cells has demonstrated that remyelination of the cervical injury site and the restoration of movement to the  limbs of these animals may help restore function in spinal cord injuries victims in the future.

"Camp Lejeune sees rise in male and female breast cancer"

Cover up by Marine Corp toxic dump
The Marine Corps still hasn’t notified everyone who drank tainted water at Camp Lejeune of the health risks like many kinds of cancer including male breast cancer, birth defects and miscarriages all coming from their own drinking water.malebreastcancer

Seems that dry cleaning chemicals were dumped into at least two water distribution systems at Camp Lejeune. Many Marines, sailors, their families and civilian employees have been affected by the contamination. This water tested positive for tetrachloroethylene, vinyl chloride, benzene, toluene, ethylbenzene, and xylene. These chemicals are commonly used in dry cleaning.
Marine Corps had known about these chemicals in the base water supply since 1980. Mike parents were consuming the contaminated water in 1967, when they were expecting him. He was a small baby, born with a persistent skin rash, and developed other health problems as he grew up. His parents, along with many other base residents, have developed more than the average number of health problems. Camp LeJeune’s water supply was contaminated for 30 years. This preventable water problem and the resulting health disaster may have affected an estimated 800,000 to 1 million former Marines and their families.
This total disregard for human life is appalling.
Seems Congress will have to demand that all the old records be handed over and the problem be responsibly addressed. Since the Marine Corps had their own hazardous material regulations and potable water standards in place dating back to 1963, but chose not to follow them. IF found guilty must be help responsible for the care of all these victims. This type of dumping is preventable.

Clues to preventing cancers

For many years Integrated Medicine has known that many factors play into creating cancerous conditions in the body. Some of

Vitamin D3
Vitamin D3

these include, but are not limited to eating foods that create an acidic condition in the body like meats, milk products, processed foods and sugar. Anything that changes the pH to acidic from the normal alkaline can create a breeding grounds for cell/DNA changes including long lasting deep seated repressed emotions.

Now Cedric Garland, DrPH, professor of family and preventive medicine at the UC San Diego School of Medicine, and his research team explain that with enough vitamin D and calcium present, cells adhere to one another in tissue and act as normal, mature epithelial cells. If there is a deficiency of vitamin D, cells can lose their sticking ability as well as their identity as differentiated cells. When this happens, they may revert to a dangerous stem cell-like state and become cancerous.

In 2008, Dr. Garland and his colleagues found an association between a lack of sunlight exposure, low vitamin D and breast cancer. In earlier work, they showed linkages between increased levels of vitamin D3 or markers of vitamin D and a lower risk for breast, colon, ovarian and kidney cancers, too
