rotten > Library > Medicine > DNA How did life first get started on this planet? And why does it suck so much? The answer is found in DNA. DNA was discovered in 1869, but at the time, no one really knew what it was or whether it was important. Scientists knew that it was a complicated molecule found inside the cells of living things, and they suspected it had something to do with heredity. In 1944, quantum physicist Erwin Schrodinger (of "Schrodinger's Cat" fame) published a collection of lectures titled What is Life? Schrodinger postulated that all life was somehow designed according a pre-set script that could found among the molecules of the body. Following on his discoveries in the study of subatomic systems, Schrodinger believed that information about the structure of a life form was physically encoded into the life form at a very small scale, and that the code was inherited by each generation from the previous. Schrodinger challenged his contemporaries in the life sciences to find that code. In the 1950s, two young scientists named James Watson and Francis Crick discovered that the molecules of DNA were coiled up in the double helix formation. A couple … Continue reading

DNA Structure and Function

Posted: Published on September 24th, 2015

DNA Structure and Function Background History: Mitosis in onion root tip DNA stands for deoxyribonucleic acid. DNA is pretty unusual in that it is about the only common molecule capable of directing its own synthesis. The processes of mitosis and meiosis were discovered in the 1870s and 1890s. It was observed that, as cells divided, chromosomes moved around in a cell, and people began to wonder what their function was. It was determined that chromosomes were made of protein and DNA, about which people knew almost nothing. People began to suspect that chromosomes had something to do with genetics, but couldnt explain what/how. When enough evidence was accumulated to confirm that chromosomes did, indeed, have something to do with genetics, most people thought that in some way the protein in the chromosomes served as the genetic material. People knew that DNA was also in the chromosomes, but because its structure was unknown and people didnt know much about it, few people thought it was the genetic material. Griffiths Experiment In 1928, Frederick Griffith performed an experiment using pneumonia bacteria and mice. This was one of the first experiments that hinted that DNA was the genetic code material.

Chemistry.com is an online dating service. It is the sister site of Match.com and was established by the same team that worked for that company.[1] The site's policies involve specifically pairing members for long-term relationships using methods it refers to as "compatibility" and "chemistry", hence its eponym. Chemistry.com's matching algorithm was designed by Dr. Helen Fisher, a professor of anthropology and scholar, and features interviews and contributions from her along with MSN spaces page, "The Great Mate Debate".[2] On January 30, 2009, ABC's 20/20 aired a two-hour special featuring Dr. Fisher and discussing her theory and research behind the Chemistry.com personality test and matching. The website became notable after several ads portrayed online daters who were rejected by eHarmony, including one which featured a gay man, highlighting the fact that eHarmony will not match people with individuals of the same gender.[3][4] In April 2008, Chemistry launched a new set of advertisements signifying the second phase of its long-term strategy, by taking the conventional wedding vows shared between two people and re-inventing them "Chemistry style". As of June 2013, more than 8 million people across the world have taken the Chemistry.com personality test. [5] Read this article: Chemistry.com - Wikipedia, the … Continue reading

Posted: Published on September 23rd, 2015

Hormone Replacement Therapy: Balance Your Hormones for a Better Life Hormones function as your bodys chemical messengers, playing an integral part in how each of our bodies work, ensuring that our bodies operate according to plan. Created by your endocrine glands, hormones travel through the blood stream to signal your organs and tissues to how to function properly. Our hormones labor in a specific balance with other chemicals in our body to guarantee certain results, but as we age, however, our hormones run the risk of falling out of balance, producing various side effects that range from minor, like tiredness or irritability, to major, like diabetes and weight gain. Arguably the worst aspect of hormone imbalance is feeling out of control of your body. Suddenly, your body no longer functions the way you have come to expect, and that can be scary and uncomfortable. Hormone Replacement Therapy (HRT) offers individuals the potential to feel in control of their bodies again. There are different types of hormonal imbalance, and each imbalance has different symptoms. At the Beverly Hills Rejuvenation Center, we can treat the most common hormonal imbalances with Bio-Identical Hormone Replacement, a version of HRT that utilizes hormones that are … Continue reading

HRT – Hormone Replacement Therapy – Garramone

Posted: Published on September 23rd, 2015

HRT (Hormone Replacement Therapy) refers to the replacement of estrogen/progesterone in a womans body to counteract the loss of these hormones during the cycle of menopause as a result of the natural aging process. When correctly administered, HRT addresses the health issues and symptoms that can accompany the pre, peri, and post-menopause stages. HRT that includes the use of DHEA and Human Growth Hormone as a part of its components, can also be used to effectively combat many of the biological effects of aging. Conventional HRT has a decades-long history of being approached from a One size fits all methodology with regard to mass-market, predetermined dosages. Additionally many of the hormones that have been traditionally used are synthesized from inorganic chemical elements, or animal derived substances such as horse urine. These substances are not molecularly identical (bio-identical) to human hormones, and the result is a series of side effects and health drawbacks that will be discussed below. Many women experiencing perimenopause are reluctant to begin HRT or refuse to continue with it as a result of myriad side effects. They can experience depression, anxiety, breast tenderness or even the elevated occurrence of other menopause symptoms like increased vaginal bleeding, hot … Continue reading

Bioidentical Hormone Replacement Therapy – Amen Clinics

Posted: Published on September 23rd, 2015

For many years, the most commonly prescribed drug in the nation was a synthetic estrogen made from horses urine (Premarin). Premarin in pill form is offered in five different dosages. In recent years, studies have linked negative outcomes to conventional hormone replacement therapy, such as increased risk of cancer and heart disease. Today, conventional hormone therapy is approached more cautiously. Recent years have seen the emergence of bioidentical hormone replacement therapy, which takes a more individualized, natural approach to hormone replacement. In bioidentical hormone replacement therapy (BHRT), hormones are biologically identical to human hormones on a molecular level, which is believed to help the body accept the hormone more effectively and avoid side effects commonly experienced with synthetic hormones. Additionally, bioidentical hormones are prescribed on a case-by-case basis based on the specific dosage needs of each patient. Instead of just five dosage options, none of which may be right for you, your Amen Clinics doctor can determine any dose that you specifically need and it will get made for you. This individualized approach makes far better sense than a one size fits all approach no two people are exactly the same, so why would their hormone levels be? And since … Continue reading

Hormone Replacement Therapy – Women’s Health Specialists

Posted: Published on September 23rd, 2015

Lets put menopausal estrogen use in an historical perspective: Throughout history and as women have become over-nourished, the age of puberty has become younger. The age of menopause, however, has stayed the same, on average about 52. When the ancient Egyptians were going through menopause, the average age of death was ten years before menopause. Now the average age of death for women is 78 to 80. We live nearly half our lives past menopause. In the 1960s, scientists discovered hormone replacement and its benefits: improved cognition, less arthritis, stronger bones, better sleep, and better sex. For decades now, millions of women entering menopause in America were prescribed Premarin or Prempro without much question. Premarin, a mixture of estrogens derived from the urine of a pregnant horse, and Prempro, a combination of horse estrogens and synthetic progesterone, served to replace female hormones that naturally dissipate in peri-menopausal and menopausal women, primarily estrogen and progesterone. Healthcare providers and their female patients were shocked to learn that hormone replacement therapy was not as safe as they had once thought after receiving the data from the Womens Health Initiative. The results of the study suggested that this type of hormone replacement therapy did … Continue reading

Bioidentical hormones: Are they safer? – Mayo Clinic

Posted: Published on September 23rd, 2015

Are "bioidentical" or "natural" hormones safer and more effective than hormones used in traditional hormone therapy for menopause symptoms? Answers from Shannon K. Laughlin-Tommaso, M.D. No, they aren't. According to the Food and Drug Administration (FDA) and several medical specialty groups, the hormones marketed as "bioidentical" and "natural" aren't safer than hormones used in traditional hormone therapy, and there's no evidence they're any more effective. The term "bioidentical" means the hormones in the product are chemically identical to those your body produces. In fact, the hormones in bioidentical medications may not be any different from those in traditional hormone therapy. Several hormone therapy products approved by the FDA and prescribed by health care providers contain bioidentical hormones. "Natural" means the hormones in the product come from plant or animal sources; they're not synthesized in a lab. However, many of these products still need to be commercially processed to become bioidentical. Traditional hormone therapies don't necessarily exclude natural hormones. Some FDA-approved products such as Estrace, Climara and Vivelle-Dot, which contain estrogens, and Prometrium, a natural progesterone also are derived from plants. Marketers of bioidentical hormones say their products have certain advantages over traditional hormone therapy: Some women may benefit from nonstandard … Continue reading
