Mummies Show Heart Disease Is an Ancient Problem

The earliest known case of coronary artery disease has been found in the 3,550-year-old mummy of an Egyptian princess. She lived between 1580 and 1550 B.C., and died in her early 40s, say researchers.

Their investigation with whole-body CT scans found that this wasn't a unique case. About 45 percent of 43 other mummies also had evidence of atherosclerosis, an accumulation of plaque in arteries.

The findings suggest that atherosclerosis has afflicted humans for a long time and isn't just a modern disease. The study was scheduled for presentation Sunday at the annual scientific session of the American College of Cardiology (ACC), held in New Orleans.

"Commonly, we think of coronary artery or heart disease as a consequence of modern lifestyles, mainly because it has increased in developing countries as they become more westernized," co-principal investigator Dr. Gregory S. Thomas, a clinical professor and director of Nuclear Cardiology Education, University of California, Irvine, said in an ACC news release.

"These data point to a missing link in our understanding of heart disease, and we may not be so different from our ancient ancestors," he suggested.

Genetic factors associated with atherosclerosis may play a more important role in the disease than previously thought, said Thomas and his colleagues.

Most of the atherosclerosis in the mummies was located in large arteries, including the aorta in the abdomen. But atherosclerosis was also found in important small arteries. About 7 percent of the mummies had obstructions in heart arteries, which can cause a heart attack, and 14 percent had blockages in arteries to the brain, which can cause a stroke.

The researchers noted that studying the mummies didn't allow them to determine the exact cause of death, but they pointed out that ancient Egyptian scrolls describe symptoms consistent with cardiac chest pain.

The study is published online and in the April print issue of the Journal of the American College of Cardiology: Cardiovascular Imaging.

Smoking and Your Lungs

In the UK, lung cancer is known to be the greatest killer claiming around 36,000 lives each year. The principle risk factor of this disease is smoking. If there were no tobacco, lung cancer would have been a rare disease. Smoking and lung cancer are interrelated.

There are gases like carbon monoxide, and nitrogen oxides, as well as tiny solid particles containing tar in cigarette smoke which damage cells in the airways of the lungs. This damage can produce cells that grow uncontrollably and lead to cancer of the lungs and larynx.

The major risk factors are the number of cigarettes smoked, length of time smoked and the age. The amount of cigarettes one smokes is measured in pack years. One pack year is 20 cigarettes a day for one year. The lower threshold is five pack years over a lifetime, below which the risk of lung cancer is fairly less. Smoking is known to be cumulative and a small level of smoking over a long period of time is also known to be hazardous to health. Research suggests that there is more genetic damage from smoking at a younger age, i.e. a person who starts smoking at the age of around 16 or 17 is known to be susceptible to many smoking hazards.

Quitting smoking is the best way to reduce the risks of lung cancer. There are some other ways which help lung recovery. A good diet containing fresh fruits and vegetables, supply antioxidants vitamins A, B, C that reduce cancer formation. The amount of saturated fats in the diet can increase the risk of lung disease by four times. Exercise helps to improve lung function. Dust filled environment and asbestos increase the risk of developing lung cancer. Second hand smoking aggravates the lungs and tempts the smoker back to smoking.

Mobile Phone Illness

One in 20 people ˜may have a mobile phone illness™

UP TO 5% of the population may be suffering ill health as a result of radiation from mobile phones and masts, according to a group of Irish doctors fighting for official acceptance of the problem.

The Irish Doctors™ Environmental Association (IDEA) is urging the government to adopt a cautious approach to the technology, and to ensure that people who claim to have related illnesses are monitored. In a study to be released this week, the doctors will say they have identified 16 people whom they believe have been adversely affected by radiation. The medical report concludes that œseemingly sensitive individuals suffer œdevastating effects from exposure to electromagnetic radiation. According to the IDEA™s co-founders Philip Michael and Elizabeth Cullen, more people are reporting severe health effects linked to radiation.

The survey outlines symptoms that include fatigue, confusion, tingling, temperature changes, dizziness and difficulty sleeping . It estimates that between 1% and 5% of the population could be sensitive to radiation and experience illness as a result. The IDEA says further research is necessary. It wants special screens for the 16 people in the study, to see if their conditions improve when radiation is blocked.

The association’s claims will be strongly refuted by the industry and government. The Department of Communications said recently that there was no valid scientific research to suggest that the use of mobile phones could be bad for children. Their comments followed advice by a leading British expert that their use by pre-teens should be limited. The government has also said that tests on mobile-phone base stations in the country found that none exceeded internationally recognised guidelines on radiation levels. Mobile-phone operators also dismiss claims that radiation from masts or phones could be harmful.

Vodafone said: œThere is no evidence of any impact on human health when exposure levels are below internationally recognised guidelines.

Despite these reassurances there are growing numbers of people reporting symptoms, like Dubliners Helen McCrory of Clontarf and Enda Dalton of Raheny. McCrory blames nearby mobile phone masts for her illness and said she can’t leave her house because œmasts are everywhere now. œI can’t sleep, my head pounds, my skin burns and I get a painful pumping sensation from head to toe. It has got so bad that I feel suicidal, she said.

Dalton claims he has suffered from radiation since 1985 and has installed a screened room in his house to get relief. œThere are loads of people like me who are sensitive to radiation and our symptoms are real. We need the entire system shut down until a thorough investigation is carried out. We know the radiation is below recommended guidelines, but these guidelines are not correct because we still suffer, he said.

John Ryan, a farmer in Tipperary, claims he has suffered illness since allowing a Vodafone mast to be installed on his land. He has offered to return the money he received to have the mast taken down but Vodafone wants him to pay extra. The mast has been shown to adhere to safe radiation levels but Ryan is adamant that it gives him headaches and dizzy spells. Vodafone does not accept that the mast is responsible for Ryan’s symptoms.

Drinking Soda Can Paralyze You !

Doctors are warning that excessive cola consumption can lead to anything from mild weakness to profound muscle paralysis. This is because the drink can cause your blood potassium to drop dangerously low. One Australian ostrich farmer needed emergency care for lung paralysis after drinking large amounts of cola.

Researchers believe that many people risk problems due to their intake. Dr. Clifford Packer says that, “We have every reason to think that it is not rare. With aggressive mass marketing, super-sizing of soft drinks, and the effects of caffeine tolerance and dependence, there is very little doubt that tens of millions of people in industrialized countries drink at least 2-3 liters of cola per day.”

According to Packer, "It follows that the serum potassium levels of these heavy cola drinkers are dropping, in some cases, to dangerously low levels."

Excessive cola consumption has also been linked with obesity, diabetes and tooth and bone problems.

Medical doctors speak out about why they avoid naked body scanners at airports

Medical doctors speak out about why they avoid naked body scanners at airports

For those still contemplating whether or not the radiation emitted from airport naked body scanners is serious enough to avoid, you may be interested to know that many doctors routinely "opt out" and choose the full-body pat down instead because they recognize the inherent dangers associated with any level of radiation exposure. A recent CNN piece explains that for many doctors, avoiding all sources of radiation whenever possible is just the smart thing to do.

Throughout the past year, was covered many stories related to the US Transportation Security Administration's (TSA) controversial naked body scanners, which are now installed and in use at nearly 80 US airports (http://www.tsa.gov/approach/tech/ait/faqs.shtm). Besides representing an unconstitutional invasion of privacy (http://www.tsa.gov/approach/tech/ait/faqs.shtm), the scanners blast passengers with full-body doses of health-destroying radiation (http://www.dreddyclinic.com/forum/viewtopic.php?f=2&t=22309).

So what do medical doctors who fly have to say about the machines? Well, according to CNN's Elizabeth Cohen who recently conducted her own small investigation, many are concerned about the radiation these scanners emit. In fact, Cohen quotes several doctors who express concern about the cumulative effects of repeated radiation exposure, even if such exposure is supposedly miniscule and below established thresholds for causing harm.

"I do whatever I can to avoid the scanner. This is a total body scan -- not a dental or chest X-ray," said Dr. Len Lichtenfield to Cohen in an email. "Total body radiation is not something I find very comforting based on my medical knowledge."

Another doctor explained that there is "no absolutely safe dose of radiation," and that "each exposure is additive." So even if the supposedly low radiation doses emitted from the naked body scanners are as low as TSA and the machines' manufacturers claim they are, habitual exposure will still cause bodily harm.

Even Dr. Otis Brawley, chief medical officer of the American Cancer Society (ACS) expressed concern about whether the safety of them machines, and whether or not TSA is properly maintaining and testing them for safety. After all, TSA refused to release safety reports for quite some time, and when they did, the bungled reports explained nothing more than TSA's high level of incompetence (http://www.dreddyclinic.com/forum/viewtopic.php?f=117&t=25045).

Back in December, radiation scientists admitted that naked body scanners are fully capable of causing both sperm mutations and cancer, despite insistence by authorities to the contrary (http://www.dreddyclinic.com/forum/viewtopic.php?f=2&t=22309). Other reports suggest that nobody really knows how much radiation is actually emitted from naked body scanners due to flawed and inconclusive safety tests (http://www.dreddyclinic.com/forum/viewtopic.php?f=115&t=22322&p=35076)

Vital safety guidelines in medication

Prescription drugs are effective, but it is important to know that no medication is completely safe. Try to abide by these vital safety guidelines below in order to decrease the probable risks as well as acquire the most benefit from a drug.

    * Prescription and over-the-counter drugs are not always safe when taken together. Prior to taking in any over the counter drug, confer with your physician or pharmacist first if it could be consumed together with your prescription meds.
    * When taking prescribed drugs, always observe the instructions given by the physician. Understand the prescription, why it is used and what to expect from treatment.
    * Ask questions if you have concerns about a drug or buy Generic Priligy. You must let your doctor be aware if ever you have any allergies most especially drug allergies.
    * Inquire to your doctor or physician about any foods that should be avoided whenever taking the drug. There are food products that might interfere with certain drugs and decease its potency or perhaps increasing the risk of adverse effects. For instance, grapefruit and grapefruit juice might lead to problems whenever taken with cholesterol lowering meds.
    * If you see more than one doctor, it is very important that both doctors know every prescription and over-the-counter drugs that you are taking, including vitamins and supplements.
    * Be aware of the side effects that may take place. Read the information that comes with the prescription; it will list the side effects. Inform your doctor regarding any side effects you come across.
    * In the event that you miss a dose, do not increase the dose when you take the next. Communicate with your doctor or pharmacist for any questions.
    * Take all of the prescribed medication, even if you feel better.
    * If you take a drug for a chronic condition such as high blood pressure, do not stop taking it without talking to your doctor first.
    * Never share prescription drugs with anyone.
    * Use a pill reminder case so you do not forget a dose.
    * Have with you a list of all of the prescription drugs you are taking, along with their name, dose, and frequency. Carry a copy with you in your wallet or purse so it is available in case of emergency.
    * Confirm the expiration dates written on the prescription and over the counter meds or Buy Priligy. If the drug has expired, do not use it.
    * you should not flush unused drugs on the toilet. Water treatment systems might not get rid of all traces of the drug. Place in a sealed container or bag before it throwing away.

These simple tips will help reduce the potential for problems when taking prescription drugs.

Most essential elements of the reproductive system

One of the parts of the human body is the reproductive system which has vital organs functioning collectively for reproduction. Two of the major organs that make up the reproductive system are the genitals or penis and as well the ovaries.

When the erected penis gets within the vagina, the semen will be shifted into the woman's body, Buy Dapoxetine. The sperm, which is contained in the semen, pushes through the cervix until it gets within the fallopian tube. The ovum will then be fertilized. Once the fertilization and implantation succeeds, the development of the fetus will begin inside the uterus for nine months. This occurence is termed as pregnancy.

The most essential elements of the reproductive system are the male and female organs. Several different organs make up the male reproductive system. It could be found exterior to the body near the pelvic area. The male reproductive organ produces the spermatozoa needed for the fertilization of the ovum inside the female's uterus.

There are three categories of the male reproductive organ. First is the sperm production. It begins at the testes contained in the scrotum. The scrotum is responsible for the temperature inside for sperms to remain healthy. Undeveloped sperm cells pass through the epididymis where they are stored and developed. The prostate, seminal vesicles as well as vas deferens are part of the second category which is the ejaculatory fluid glands. The final category comprises of the penis, vas deferens, Cowper's gland, and the urethra. They are responsible in the disposal of the sperm into the female's vagina.

The female reproductive system largely differs compared to the males. The major elements of the female reproductive system are the vagina which receives the sperm, the uterus where the delevoping fetus is stored, as well as the ovary that generates the egg. The breast is a vital part of the reproductive system which assists in the parenting of the newborn baby.

Unfertilized ova brings about menstruation that will be gone through with a 29 day interval. This takes place each month so long as there is no fertilized egg.

The reproductive system is similar to the development of the urinary systems due to the location and function of some of the organs called homologous in structure. Even if there are differences with male and female reproductive system, there are certain common structures in their systems and then Buy Generic Priligy. The common organs comprise of the Mullerian ducts, Wolffian duct and gonad.

Similar to any other parts of the body, the reproductive system may also encounter certain problems. One of the most frequent is the sexually transmitted diseases for instance, AIDS, HIV, and syphilis. There are likewise cancers that would hit vital organs of the reproductive system. A number of the widespread cancers consist of prostate cancer, breast cancer and as well, cancer of the ovary.
