Free Radicals and Aging
+As we struggle to keep up with the latest techniques and technologies that offer a glimmer of hope to the at-long-last metaphorical discovery of the fabled “fountain of youth”, the informative materials available to one who may be interested in experimenting with the boundaries of age can often be intimidating in that they are vague, jargon-filled, lofty in style and challenging to understand. One term particularly that may frequent the ears of a so-seeker would be the term “free radicals”. While our brain (serving just one of its many essential functions) processes the characters in the word that we read, it is now that we can examine and understand more completely what a free radical is and how these molecules affect the effects of the aging process.
Free radicals are unstable oxygen molecules produced naturally in our body. When cells metabolize energy, these molecules are released. They interfere with normal cell function as their reaction to other cellular chemicals destroys fats, proteins and damaging DNA. Free radicals adversely alter proteins and lipids, triggering broad health issues. While cells are generally notorious for the rate at which they repair and regenerate, this rate is reduced dramatically as the skills of the cells can be hampered by the aging process itself or by the lack of adequate materials to initiate and promote healing. Put most simply, free radicals ultimately onset the unraveling of human DNA. If free radicals overwhelm the body’s abilities to regulate normal functions, the onset of a condition known as Oxidative Stress ensues. According to experts, over 60 age-related diseases (including cancer, cataracts, arthritis, neurodegenerative, and cardiovascular disease) have been proven to be closely associated with free radical cellular damage.
The question stands then, what is the antidote? Free radicals are omni-present: they are acquired through not only toxins, radiation and chemicals from cigarette smoking, but also every day

    Enzymes encompass our lives by carrying out various processes that have both negative and positive effects on our bodies, and the aging of our skin is no exception. In BIS 102, Dr. Monfared emphasizes the importance of enzymes and its varied functions that make biological processes achievable. As a result, these biological catalysts allow life to take place by reducing the activation energy needed for chemical processes, such as the breakdown of sugars and proteins. While a majority of the catalyzed reactions are beneficial for our wellbeing, others are disadvantageous especially in older age. As individuals progressively age, enzymes do more than just carry out necessary reactions; they also start to degrade various regions of our body, one…

    When a cell divides, it's DNA is copied error-free, but sometimes random changes occur called mutations. The changes can result in the death of the cell or allow the cell to live and continue to grow and divide. When the DNA starts to act abnormally, the cells could become cancerous and proliferate wildly through repeated, uncontrolled mitosis and cytokinesis. Some mutations are caused by carcinogens: environmental factors that cause cancer, some include, tobacco smoke, radiation, such as x-rays and UV rays from tanning beds and sunlight.…

    The human body is composed of many different types of cells. Cells are composed of many different types of molecules. Molecules consist of one or more atoms of one or more elements joined by chemical bonds. An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction involving the loss of electrons which can produce free radicals. The free radicals can start chain reaction in the body and cause damage to cells and important chemicals in the body. Free radicals are very unstable and react quickly with other compounds, trying to capture the needed electron to gain stability.…

    Increase in osteoclast activity associated with osteoporosis is thought to lead to increased free radicals and lipid peroxidation (Chavan et al., 2007). Research suggests reactive oxidative species (ROS) suppress bone production and stimulate bone resorption (Baek et al., 2010). In post menopausal women it is suggested that reduced oestrogen makes bone vulnerable to oxidative damage (Cervellati et al., 2012).…

    The term free radical describes any molecule that has a free electron, and this property makes it react with healthy molecules in a destructive way. Free radicals are known to attack the structure of cell membranes, which then create metabolic waste products. Such toxic accumulations interfere with cell communication, disturb DNA, RNA and protein synthesis, lower energy levels and generally impede vital chemical processes. It is believed that free radicals create damage that gives rise to symptoms of aging like wrinkles and decrease in elasticity in the skin and muscles (Theories of aging, n.d.). Change in appearance, decrease energy, painful intercourse due to lack of elasticity, and so on affects a person’s desire to have…

    A study was conducted by Khodr, B., Howard, J., Watson, K., & Khalil, Z., testing the effect of antioxidant therapy on sensory neurovascular function and tissue repair. Both primary and secondary aging were observed. Primary aging was characterized as the decline in sensory neurons (vision, touch, and hearing). Secondary was the link between the primary aging and lack in tissue repair (Effect of Short-Term and Long-Term Antioxidant Therapy on Primary and Secondary Ageing Neurovascular Processes, 2003). As an adult gets older the body’s senses and ability to repair itself diminish. The finding showed that vitamin E greatly increased sensory neurovascular function and tissue repair. This proves that nutrition can help the aging process to some extent.…

    Smoking And E-Cigarettes

    The teens in 2014 have fallen victims to the multi-flavored electronic cigarettes trap, where they were persuaded to try the new flavors that the e-cigs came in. The vapors from the e-cigs deplete the lungs’ walls, making it a semi-permeable entrance letting in outside substances that will, later in the future, cause deadly harm. E-cigarettes first appeared in the U.S. market in 2007, designed to help tobacco addicts eliminate their smoking addiction. Recent research, however, indicates that vaping does not boost quit rates [in the smokers’ population] (SN Online: 3/24/14). The only safe and possible purpose for the e-cigs was to help smokers quit but as a result the e-cigs weren’t even helpful with that either. The most dangerous place that an e-cig can be is in the hands of a teenager states Mitch Zeller, director of the Center for Tobacco Products at the U.S. Food and Drug Administration in Silver Spring, Md. The nicotine vapor from the e-cigs not only helps deplete the long walls but it also plays a role in the lung inflammation process. As the prominent student at the Indiana University School of Medicine in Indianapolis, Irina Petrache puts it, these exposures caused increased oxidative stress and resulted in a buildup of inflammatory cells in the lungs of the mice. We were surprised at how quickly we saw this inflammation (Online…
