Angiotensin-converting enzyme inhibitor
|
view preview
Angiotensin-converting enzyme (ACE) inhibitors are a remarkable class of drugs for treating hypertension – high blood pressure. These drugs work by interfering with the enzymes that convert an inactive chemical known as angiotensin I to an active form, angiotensin II. Angiotensin II increases the retention of salt and water in the body, raising blood pressure. ACE inhibitors interfere with, or inhibit, the formation of angiotensin II, resulting in relaxed arterial walls and lowered blood pressure. Since the release of the first ACE inhibitor in the 1980s, known generically as captopril, there are now several different ACE inhibitors available on the market. Many of them are also available in combination with other types of hypertension medic ...

Doctor of Osteopathy vs. Doctor of Medicine
|
view preview
The United States has two kinds of physicians, the Doctor of Medicine (MD) and the Doctor of Osteopathy (DO). Both use medicines, surgery, and other standard methods of treating disease. DOs, however, place special emphasis on problems involving the musculoskeletal system, which includes muscles, ligaments, bones, and joints. Nevertheless, both doctors receive virtually identical training, and are equally licensed in all 50 states. Osteopathic medicine holds that true health involves complete physical, mental, and social well-being, rather than merely the absence of disease. In this system, the body has a capacity for health that the physician helps the individual attain. The osteopathic physician, therefore, treats the whole patient, consid ...

Child with ADHD vs. one who is simply more active
|
view preview
What's the difference between a child with attention-deficit hyperactivity disorder (ADHD) and one who is simply more active than other children?Many children are rambunctious, to an extent that their parents or teachers find somewhat worrisome. Figuring out how to distinguish between normal high-energy levels and pathological overactivity can be quite difficult. Furthermore, the distinction can be complicated by parental tendencies to be permissive and to fail to set up clear rules, reprimands, or restrictions for when a child steps outside the limits. Figuring out how to make this distinction is not a trivial issue. Children diagnosed with ADHD are usually prescribed methylphenidate (Ritalin) or other medications that lessen their activity ...

What do chiropractors do?
|
view preview
Chiropractic medicine is an approach that is derived from the Greek roots " cheir," meaning hand, and " praxis," meaning practice, and was formulated by the founder of chiropractic, Daniel David Palmer (originally of Canada), to mean " done by hand." The emphasis in chiropractic is on the use of physical manipulation or adjustments to correct misalignment of the spinal vertebrae and other musculoskeletal joints to improve the function of the related organs and musculature. The main treatments used by chiropractic physicians are adjustments, or physical manipulation of the musculoskeletal system. Chiropractors also use heat and/or cold therapy, immobilization (with splints, for example), hydrotherapy, ultrasound, and massage. Chiropractic treatme ...

Strange disease that causes fibers to grow underneath the skin
|
view preview
Imagine a disease whose presence is marked by a feeling of something crawling along your skin, stinging every part of your body as if there is insect or parasite infestation that doesn't go away. Not only that, but your skin is plagued with the presence of multicolored filaments that lie under, are embedded in, or project from skin. Morgellons disease (pronounced with either a hard or soft "g") is a highly misunderstood skin condition that was first reported in the USA in 2002, although may have a longer history depending on where you look. The characteristic filaments described earlier are microscopic, visually resembling textile fibers, and are white, black, or a more vibrant color, such as red or blue (left image). In addition to fiber p ...

What is the purpose of stress?
|
view preview
The stress response exists for the purpose of survival. When we experience stress, our sympathetic nervous system activates, blood pressure and heart rate increase, and often we begin to sweat. These physiological reactions prepare us for "fight or flight." Our bodies are at optimal physical performance and alertness levels, and we are therefore optimized for survival in a physically challenging situation. Sometimes we use this physiological activation to our advantage: Consider a champion weightlifter who, prior to lifting an extremely heavy weight, "pumps himself up." By doing this, the weightlifter is attempting behaviorally to elicit a stress response from his brain and body in order to achieve the highest level of physical performance ...

The Science Behind Fasting and Bad Breath
|
view preview
Fasting is a practice that has been followed by various cultures and religions for centuries. It involves abstaining from food and, in some cases, beverages for a defined period. While fasting can have several physical and mental benefits, it is not uncommon for individuals to notice an unpleasant odor in their breath during fasting periods. Let's explore the reasons behind this phenomenon and uncover the science behind why one's breath may smell when they've fasted. When we fast or restrict our carbohydrate intake for an extended period, our body undergoes a metabolic state called ketosis. During ketosis, the body shifts its primary source of energy from glucose (derived from carbohydrates) to ketones, which are produced when the liver brea ...
