Gemstones are mineral crystals or organic materials that have been cut and polished into beautiful items by skilled craftsmen. The minerals are naturally formed, solid, inorganic chemical compounds found in rocks. Each mineral has a fixed chemical composition and regular atomic structure, which gives it the specific hardness and color it possesses. Many natural crystals are attractive enough to be displayed. However, most of these crystals are faceted and polished to enhance their appearance. Few gems, which are called organics, come from plants and animals. These gems include ivory, amber and pearl. There is a category of gemstones known as synthetics. They do not have any natural origin and...

Emphysema is defined as a chronic illness that results from the lung's tissue elasticity being destroyed and the lung airspaces being enlarged. It is a kind of COPD, chronic obstructive pulmonary disease, along with asthma and chronic bronchitis. Unfortunately, it can be fatal. As with all the treatment of any health concern, emphysema treatment begins with knowledge of the disease. Doctors diagnose the disease based on a group of emphysema symptoms that may differ somewhat between patients. There are similarities between asthma, chronic bronchitis and emphysema symptoms. Asthma and chronic bronchitis treatments differ from emphysema treatment, so doctors attempt to differentiate between the...

(NC)-Each year, a growing number of Canadians make the heartfelt decision to give one of their kidneys to a relative or friend in need. While this life-saving gesture is a blessing for the recipient, it can pose challenges on a number of levels for the donor. The standard practice for removing a kidney is to make a 20- to 30- centimetre incision across the side of the body, go through two to three layers of muscle and remove 10 centimetres of rib. With incurred scarring and several months of subsequent inactivity, the decision to be a donor is understandably daunting for many. Yet thanks to an innovative medical procedure called laparoscopic or "keyhole" surgery, painful incisions and long recovery...

The third annual Prostate Cancer Symposium may not seem a likely place to hear about aerobic or resistance exercise. However, there was an interesting report proving the value of resistance and aerobic exercise on those undergoing radiation therapy for prostate cancer. Normally, you might expect that it would be better to rest and preserve your strength to fight the cancer. But, researchers found that by doing either aerobic or resistance exercise significantly improves both the aerobic capacity and decreases fatigue. Fatigue is one of the major negative results of radiation therapy. Roanne Segal, M.D., of the University of Ottawa in Ontario and the Ottawa Regional Cancer Center and her team divided...

Earlier we only had x-ray method of detecting a disease but since last 10-15 years we have other methods like ultrasound, and other imaging methods. Imaging simply means creating an image of the insides of your body and radiology is the use of radiation for different types of "imaging," including X-rays and radarscopes. When doctors take the help of radiation for various types of imaging then it is called the science of radiology. Actually there are many other names for it. You can call it radioscopy or clinical radiology. When radiology is used for medical purpose then it is called clinical radiology. Radiology is used for treating and diagnosing various types of disease or injuries. Radiation...

The performance of RayBans as eyewear is almost close to legendary. No eyewear has been as much imitated in styling and has sold as many as the RayBan.

RayBan sunglasses are quality eyewear. It stands for exceptional value, classic style and excellent if not lucky market exposure. It is not often that something that is worn by the father can still be in fashion today with the son. An amazing feat that RayBan eyewear would not have accomplished if it does look so good and work so well. It enjoyed to have continued and prestigious...

Patients who believe in the effectiveness of their pain medication will experience greater pain relief, finds a University of Michigan study published in the Journal of Neuroscience. Just thinking that a medicine will relieve pain is enough to prompt the brain to release its own natural painkillers, results indicate. The study, funded by the National Institutes of Health, provides the first concrete evidence that endorphins, the brain's own pain-fighting chemicals, play a direct role in the phenomenon known as the "placebo effect." Endorphins behave similarly to opiate drugs, such as heroin and morphine. They bind to receptors and stop the transmission of pain signals along the nerve pathways...

The popularity of radiography in the field of medicine has grown exponentially. Radiographers were encouraged and trained to adopt the new technology of conducting diagnostic tests involving X-rays. It started with fluoroscopy, computed tomography and mammography. Medical radiographers later added ultrasound and magnetic resonance imaging to the list of specializations. Medical radiographers are experts who make use of imaging instruments to x-ray various body parts of human beings, in order to diagnose health problems properly. The procedure incorporates medical imaging actions to identify health related problems. Besides this, professionals also prepare the patients for radiology examinations by...

Malta as part of the British Empire was a strategic naval outpost in the Mediterranean Sea. For many years it provided hospital services to sailors in the Royal Navy and helped ensure that British supremacy in the Mediterranean sphere of influence was upheld. Today this long tradition of British hospital patients in Malta is returning; as medical tourism increasingly becomes an option for British citizens. Medical tourism is not a new idea; the ancient Greeks visited a territory called Epidauria; fabled as the sanctuary of Askelepios, the healing god. The spa towns dotted all over Europe can also be seen as early examples of the medical tourism industry. The industry has become popular of late and...

X-Rays have been in use as a medical imaging technique since 1895 when Wilhelm Roentgen found that he was able to create images of internal bodily structures such as bones and tissues by passing electromagnetic waves through the body. He labeled the phenomenon "X" because he did not fully understand what made up the "rays". From that time forward, X-Rays have been the building block upon which medical imaging technology and medical imaging equipment have been built. Even though the X-Ray (or radiograph) has been a crutial tool for medical imaging, this approach has always had the down side that the images produced are indistinct. The images require very careful study and interpretation. Scientists...

Description Celiac disease is a type of malabsorption syndrome. During digestion, food is broken down into nutrient molecules that can be absorbed by the bloodstream. In people with malabsorption syndrome, nutrients are not released into the bloodstream but are instead eliminated in the stool. As a result, the body does not get the nutrients it needs from food. Also called celiac sprue, celiac disease is a relatively uncommon ailment, affecting approximately 1 person in 1000. It is caused by a sensitivity to gluten, a substance found in wheat, rye, oats, and barley. With extended exposure to gluten, the intestinal lining loses the tiny folds through which nutrients are absorbed and stops producing...

Most women are familiar with mammography as our "gold standard" for breast cancer screening. However, there are additional tools available that women can add to their arsenal. One of the most effective tools in breast cancer screening is breast self-exam (BSE). However, BSE works best when women are appropriately trained in the procedure, and then followed-up with annual clinical breast exams (CBE) from their physicians. In a 2000 University of Toronto study, approximately 20,000 women were screened for breast cancer with BSE and annual CBE, and 20,000 were screened with BSE and mammograms. After more than 10 years, the BSE and annual CBE reported 610 cases of invasive breast cancer, and 105...

What is this condition? Pneumonia is an acute lung inflammation in which the lungs fill with a fibrous material, impairing gas exchange. With poor gas exchange, the blood has too much carbon dioxide and too little oxygen. People with normal lungs and adequate immune defenses usually recover fully. However, pneumonia is the sixth leading cause of death in the United States. Classifying pneumonia Pneumonia can be classified by location or type, as well as cause . • Location: Bronchopneumonia involves the lungs and small airways of the respiratory tract. Lobular pneumonia involves part of a lobe of the lung. Lobar pneumonia involves an entire lobe . • Type: Primary pneumonia occurs when a...

Like humans, our canine friends often suffer back pain. It is especially prevalent in small breeds like Dachshund and Lhasa apso, but bigger breeds like German Shepherds and Great Danes can also suffer. Additionally, dogs that are overweight are more likely to have back problems than their leaner counterparts. Some back injuries involve nothing more than sore muscles. However, for some, disc injury or degenerative disc disease may be the problem. This can cause extreme pain, lost muscle control, nerve damage and paralysis. Like man, a dog's spine is made up of small bones called vertebrae. They run from the base of the skull to the end of the tail. Flexible discs made of cartilage provide a cushion...

[AD] Children and Acid Reflux Acid reflux is a condition normally associated with adults. Sadly, many children also suffer the effects of acid reflux. This desease, also referred to as gastro-esophageal reflux, occurs when stomach contents churn and rise up into the esophagus, the tube connecting the stomach with the mouth. A muscle between the esophagus and the stomach, known as the lower esophageal sphincter, is responsible for keeping the stomach closed off until food is swallowed. The lower esophageal sphincter then opens up and allows the food into the stomach before closing again. Although Acid reflux can begin during infancy, it can carry over into early childhood. Though quite common in...

Without a doubt, total immersion in any culture is the ideal way to learn a language quickly and fluently. The advantages include enveloping a suitable accent, learning the common use of the language (how it is spoken locally) and providing a clearer understanding of the semantic and grammatical nuances of it. For a widely spoken language like Spanish, there's no faster way to learn it! This approach to your linguistic studies begins by traveling to, and living in an area where Spanish is the official and (hopefully) primary language. You're not just going to pick it up by living there though, so make arrangements for regular classes or private instruction by someone qualified to teach non-native...

Most drunk driving cases start out with a contact between the driver of a motor vehicle and a police officer. While the police have the right to approach and speak with any citizen, they do not have the right to detain and investigate a citizen unless they have "probable cause". Probable cause is the legal reason an officer needs to detain and investigate. If the dui attorney can show to the judge the officer did not have probable cause, the case can be dismissed. Most detentions begin with the officer pulling over a driver who has committed a vehicle code infraction. The common reasons alleged by the police are based on poor driving - speeding, weaving within or outside the lane, running...
