Have you lost your contact lenses for the Nth time? Feeling frustrated, angry at yourself, and close to panic? Almost everyone who's ever worn "contact lenses" on a regular basis has experienced dropping contact lenses on the floor, on the table, in the sink, and every where else. And anyone who has ever dropped his or her contact lenses would have been thinking the same thing - "Drat! Here we go again. I wish I didn't have lousy vision so I don't have to wear my contact lenses ever again."So you dropped a contact lens, what's the big deal? Contact lenses are made of clear transparent material that are invisible to an observer when placed on the eye. They are normally worn by the person to correct for blurred vision. How do you think a person who has blurred vision feels when he or she has to search for a nearly-invisible, very small object without the optical aid that he or she normally uses for close range vision? That's right. It sucks!If you see your friend crawling on the carpet with his or her face just about a foot above the floor, chances are, that person lost a contact lens! For all you contact lenses wearers out there, does this sound familiar?If you've had it up to your neck with your contact lenses, how about going for a more permanent solution? If there was a way for you to stop wearing your contact lenses, or any other eyewear for that matter, while still having clear vision, would you do it? Is that a YES?Did you just say yes? YES! You see, my friend, there is this eye procedure called LASIK surgerythat can help you get rid of your contact lenses permanently. "LASIK surgery" was the most common eye procedure performed in the United States last year, and the reason it has become so popular is because it can fix some vision problems like myopia and astigmatism permanently. With your vision problems gone, you won't have to look for your LASIK surgery ever again! Good riddance!LASIK surgery has produced very good results, that it is definitely worth learning more about it.
Being overweight and obese is viewed by many as a serious and fast growing public health problem. More and more people are now adding extra weight because of several factors which includes family genetics, eating habits, lifestyle, and so on. This health condition not only gives the person a feel of embarrassment in social circles, but also faces a dangerous health condition.Obesity is defined as the excess or having too much body fat. Being overweight on the other hand, refers to those who weigh too much. Both of these conditions refer to weight as those that come from the bone, fat, muscle, and body water of a person. Either way, both terms apply to people who have excess weight, more than what their height applies for.Several health problems may arise if a person is considered as "overweight and obese" . From arthritis, asthma, high blood pressure, sleep apnea, high cholesterol, gallstone, fatty liver, insulin resistance and diabetes, to depression, these conditions may seriously risk one's health, putting an overweight or obese person at risk.In line with this, anti-obesity drugs have been available for people who are experiencing obesity or being overweight. This particular kind of medication includes all pharmacological treatments designed to decrease or control a person's body weight. Since these drugs are expected to alter one of the fundamental processes of the human body, anti obesity drugs are medically prescribed only for people with morbid obesity, or where weight loss can be life saving. A new and recent study on the effect of an anti-obesity drug called rimonabant found out that it reduced points of liver damage, decreases levels of pro inflammatory proteins, and improved on lipid profiles. Since obesity is associated with changes in tissue and blood levels of pro-inflammatory and anti-inflammatory proteins and hormones, it is the main cause of several metabolic syndrome features and their complications, including hepatic steatosis (an accumulation of fat in the liver). According to researchers, as they studied the effect of rimonabant on the liver, they found out that the treatment with this medication reduced liver enlargement, completely eliminated hepatic steatosis, and decreased blood levels that indicate liver disease and liver damage. The results from this study also showed an improvement in abnormal lipid levels, which can lead to cardiovascular diseases. It also lessened the levels of cholesterol and free fatty acids, and with the treatment of rimonabant, normalized levels of adiponectin are reached (a hormone that plays an important role in metabolic disorders). This study further suggests a potential clinical application in the treatment of "liver disease" s connected with obesity and the metabolic syndrome. Researchers from this study noted that while weight loss is achieved by burning more calories than consumed, the reality may not be that simple. But then again, this medication also offers a weakened rate due to its side effects such as nausea, dizziness, depression and diarrhea. In any case, this medication should be further studied to prevent any unaccesaaptable side effects that can harm people who are dealing with being overweight and obese.
It is important to be fit, everyone knows that. Your physical fitness has a big impact upon how you feel about yourself, and how much effort your body has to expend in order to keep working. Lack of physical fitness has supposedly reached an epidemic proportion in America, though the truth is that Americans are obsessed with physical fitness, and TV doctors and celebrities alike make a fortune through selling fitness videos and books to the public. Unless youre planning to buy em all and use them as weights to lift up and down every day, none of these will ever do your physical fitness any good at all.The best way to improve your physical fitness is by incorporating regular activity into your daily routine. It is not necessary to take out full membership of your local gym, or even attend one exercise class. What it does mean is choosing an activity that increases your heart rate, or improves your strength and general flexibility. Walking a few more blocks, doing some gardening or housework, climbing the stairs, are all examples of something that can fit quite easily into your routine, but which can also increase your physical fitness. Taking the elevator, driving the car to the shop at the corner of your street, and spending more time in bed are all things that will not improve your fitness level.A healthy lifestyle cannot be a fad, or something that you will do next year. It should be on your to-do list all year round, not just as a New Year Resolution that you never intend to keep. Once you start on an exercise regime, you will need to keep that up for the rest of your life; or your physical fitness will be lost, and you will have to start all over again. Without regular exercise, the muscles reduce, and fat takes its place (muscles do not become fat, they merely move over to make more room for it if they arent used). It is therefore important that you choose a regime that is going to keep you interested in the long term; every year throws up a new fitness fad, but most people take them up and then discard them after a fortnight. Instead, choose something that you enjoy. If the thought of being instructed on stepping up and down on a plastic board fills you with scorn, then you might try something else martial arts are always popular, and a physical fitness regime which incorporates some kind of team sport will also help to keep you interested.Remember: physical activity everyday is the key to fitness, and that is what is important. Improving your physical fitness can provide you with more energy, and will help you to feel more positive about yourself.
I will outline in this cosmetic dentistry article the most frequently asked questions along with their answers, you will sure find them useful for your "cosmetic dentistry" research.First Question: Can whitening my teeth damage them ? What are the effects ?Your teeth will become more sensitive to cold, heat and sweets. Because it's a new technology, it's long term effects are still unknown. Bleaching will probably have to be repeated in order to maintain your whitening.Second Question: Because I used antibiotics as a child, I now have darkened teeth. What can I do to make them white again?Discoloration of your teeth is called intrinsic stain and can be treated very good with bleaching. Best option in this case is to ask your personal dentist on what options you might have. You could place porcelain laminate veneers or place crowns for ex.Third Question: Why do people's teeth discolor upon aging ? Is this just a part of aging?Yes, it could be just a part of aging. The surface of the teeth becomes thin during lifetime, this it's allowing underlying dentin to shine through or in some cases, become exposed to the surface. Some people are less motivated to do something about it and this will cause their oral hygiene to suffer.Fourth Question: I am a little scared about laminates. Does it hurt to have my teeth prepared for them ? Can you tell me more about it ?It does not hurt a bit. Actually, it is a cosmetic dentistry procedure that will be ready in two visits to your personal dentist. You can also benefit from a local anesthesia if you are a highly sensitive patient. Local anesthesia is necessary in less then 40% of the cases.Fifth Question: I would like to know if there are advantages of laminates versus orthodontic treatments. What is the time required for both of these cosmetic dentistry procedures ?Yes, these two cosmetic dentistry procedures are totally different by all means. If you choose orthodontic treatments, you will have to wait more than one year and a half to be 100% completed, this is not at all the case with porcelain laminates. Porcelain laminates will take only two visits to your local dentist and will correct crooked teeth usually better than the orthodontic treatment.I am sure that you found these cosmetic dentistry questions and answer very helpful for your cosmetic dentistry research.
Healthy eating is difficult to achieve because we have so many health factors to consider and food choices to make. We know antioxidants are good for us so we want to eat lots of colorful fruits and vegetables because they contain phytochemicals like carotenoids and flavonoids which neutralize the free radicals that cause the age-related degenerative diseases. We know that we may not get all the antioxidants that we need in our food so we take supplements to ensure an adequate supply of antioxidants. But what about the actual food we eat. One of the major problems with our modern diet is that the food we eat is a tasty combination of saturated fats and highly processed and quickly digested carbohydrates. However in the last several years, people have become so concerned about fats in their diet that they have substituted carbohydrates and avoided even the good unsaturated fats in lean meat, olive oil and other plant oils. Now everybody seems to be eating a medium- to high-carbohydrate diet without giving proper attention to the type of carbs that they eat.Not all carbohydrates behave the same in our bodies. We have been told for years to avoid simple carbs like honey and white bread and eat complex carbohydrates that our body doesnt digest and turn to glucose as quickly. However determining whether a food containing carbohydrates is absorbed and raises our blood sugar quickly or slowly is not at all intuitive. Scientists have done a lot of rigorous testing over the past several years and have found that white bread and baked potatoes raise our blood sugar level much faster than honey, jams and chocolate bars. These scientists developed a numerical index called the Glycemic Index or GI to compare the ability of different carbohydrate containing foods to raise the bodys blood sugar levels or in other words the speed of conversion to glucose. GI values are determined by feeding human subjects who have fasted overnight a fixed amount of the food and then measuring their blood glucose levels at fixed intervals of time. Pure glucose is set at 100 and then other foods are compared to this profile. Testing is time consuming and the tests have to be averaged for a number of individuals. However these studies have yielded some surprising results such as the fact that the starches in rice, bread, potatoes and many types of cereals were absorbed and raised blood sugars very quickly but the sugars in fruit, candy, chocolate and ice cream did not result in prolonged rises in blood sugars. In other words many of the starchy foods had a much higher Glycemic Index than many of the sugary foods. Needless to say these results seem counter intuitive and have caused a lot of controversy in the food industry. The rate of absorption is very dependant on how the carbs are bound up with the food fiber and the particle size. For example less gelatinized products like al dente spaghetti and oatmeal have lower GI values and stone ground flours have lower GI values than finely ground flours. The fibrous coat surrounding beans and seeds stop enzymes from getting at the starchy carbs inside and will slow the digestion of grainy breads, legumes and barley. The acidity of foods also slows down digestion and vinegar, lemon juice, pickles and sourdough bread will result in lower GI meal values.The Glycemic Index is important not only to diabetics but also to non-diabetics because we need to know what foods will keep our blood sugars on an even keel and not raise them too high and then have them plummet down again causing hunger. The slow digestion of low GI foods and the gradual rise and fall in blood-glucose response helps people with diabetes control their blood sugar levels and increase their sensitivity to insulin. Low GI foods will help healthy people delay hunger pangs and promote weight loss in overweight individuals. In addition low GI carbohydrates can reduce blood cholesterol levels and also reduce our risk of heart disease. High blood glucose spikes can result in oxidative stress leading to the formation of plaque that can cause atherosclerosis and even blood clots. So keeping our blood sugar levels fairly level and low seems like what we should be trying to achieve through healthy eating. How do we go about achieving this?The first step is to look at what carbohydrates we are consuming and the GI levels of the meals that we are eating. Then we should try and ensure we have at least one low GI food in each meal to keep the overall meal GI close to 50. Most fats and proteins have no effect on the GI level of our meal because they dont contain carbs. However watch out for saturated fats and too many calories. Lets look at some meals and see what substitutions we could make. The GI values are shown in brackets.BreakfastCut back on Corn Flakes (92), Rice Krispies (82) and substitute All-Bran (32) or switch to a cereal based on oats, barley or bran. Stop eating white bagels (72), white bread (70) or whole-wheat bread (77) and switch to pumpernickel (50) or sourdough (55). Fruits are mostly low GI foods and surprisingly orange juice (46) is very good.Lunch and DinnerEat your colored vegetables and make your salad dressings with olive oil and vinegar. Avoid parsnips (97) and substitute pastas like al dente white spaghetti (38), linguini (46) or macaroni (47) for Instant white rice (87) and potatoes baked (85), red-skin peeled and boiled (88). Except for parsnips and potatoes most vegetables have a low GI value.Additional information on GI values can be found at the University of Sydney website http://www.glycemicindex.com/ or in the The New Glucose Revolution: Shoppers Guide to GI Values 2006.
