In addition purchase generic avalide line blood pressure 15080, today we know that their nutritional role extends beyond that of the preven tion of deficiency or deficiency-associated diseases best 162.5 mg avalide blood pressure medication with c. They can also aid in preventing some of the most prevalent chronic diseases in developed societies discount avalide 162.5 mg amex pulse pressure values. Vitamin C, for example, prevents scurvy and also appears to prevent certain types of cancer. Vitamin E, a potent antioxidant, is a protector factor in cardiovascular disease and folates help in preventing fetal neural tube defects . These vitamins can accumulate and cause toxicity when in gested in large amounts . Therefore, any problem with respect to the absorp tion of fats will be an obstacle to the absorption of liposoluble vitamins. The latter are stored in moderate amounts in the vital organs, especially in the liver . Hydrosoluble vitamins: The following are vitamins of the B group: [B (thiamin); B (ribofla1 2 vin; B3 (niacin); pantothenic acid; B (pyridoxine); biotin; folic acid, and B (cyanocobala6 12 min)], and vitamin C (ascorbic acid), contained in the aqueous compartments of foods. These are water-soluble compounds that are found in foods of animal and plant origin. Dif ferent from liposoluble vitamins, water-soluble vitamins are not stored in the body; thus, they should be ingested daily with food to avoid their supply becoming exhausted . The hydrosoluble vitamins participate as co-enzymes in processes linked with the metabolism of organic foods: carbohydrates; lipids, and proteins. One important difference between these two vitamin groups lies in their final destiny in the organism. An excess of water-soluble vitamins is rapidly excreted in the urine; on the other hand, liposoluble vitamins cannot be eliminated in this manner; they accumulate in tissues and organs. This characteristic is associated with a greater risk of toxicity, which means the ingestion of excessive amounts of liposoluble vitamins, especially vitamins A and E. Vita min B12 constitutes an exception because it is stored in the liver in important quantities. Action: The presence of this vitamin is required for a certain number of metabolic reactions in all animals and plants and is created internally by nearly all organisms, humans compris ing a notable exception . Currently, this vitamin is the most widely employed vitamin in drugs, premedication, and nutritional supplements worldwide . If these are not neutralized, so-called propagation or amplification is produced and, in the case of oxidation, the peroxides are again oxi dized into peroxyls . Foods are substances or products of any nature that due to their characteristics and compo nents are utilized for human nutrition. Chemical structure: Ascorbic acid is a 6-carbon ketolactone that has a structural relationship with glucose; it is a white substance, stable in its dry form, but in solution it oxidizes easily, even more so if exposed to heat. Its chemical structure is reminiscent of that of glucose (in many mammals and plants, this vitamin is synthesized by glucose and galactose). If dihydroascorbic acid is hydrated, it is transformed into diketo gluconic acid, which is not biologically active, and with this an irreversible transformation. Deficit: It is well known that a deficiency of vitamin C causes scurvy in humans, thus the origin of the name ascorbic given to the acid . Prior to the era of research on vita mins, the British Navy established the practice of supplying lemons and other citric fruits to their sailors to avoid scurvy . The oxidation-reduction (redox) reaction of vitamin C, molecular forms in equilibrium. L-dihydroascorbic acid also possesses biological activity, due to that in the body it is reduced to form ascorbic acid. Daily recommended doses of ascorbic acid are 75 mg/day (for women) and 90 mg/day (for men). Absorption: Vitamin C is easily absorbed in the small intestine, more precisely, in the duo denum. In normal inges tions (30180 mg), vitamin C is absorbed (bioavailability) at 7090% vs. The vitamin C concentration in the leukocytes is in relation to the concentration of the vita min in the tissues: therefore, by measuring the concentration of vitamin C in the leukocytes, we can know the real level of the vitamin in the tissues. The pool of vitamin C that humans possess under normal conditions is approximately 1,500 g. If there are deficiencies, absorption is very high and there is no elimination by urine. Alcohol consumption diminishes absorption of the vitamin, and the smoking habit depletes the levels of the vita min in the organism; thus, it is recommended that smokers and regular alcohol consumers supplement their diet with vitamin C. Thus, the symptoms of scurvy do not appear for months in subjects with a diet deficient in vitamin C . The L-dihydroascorbic acid molecule is better absorbed than that of L-ascorbic acid. Passive absorption is dependent on a glucose transporter and active absorption is dependent on Na. But if the daily dose of vitamin C exceeds 2,000 mg/day, the following can appear : Diarrhea Smarting on urinating Prickling and irritation of the skin Important alterations of glucose in persons with diabetes Insomnia Excessive iron absorption Formation of oxalate and uric kidney stones. A great diversity of scientific works has allowed increasing the knowledge of the biological function of vitamin C, but this has also generated doubts, given that controversies have sur faced. One of these controversial points comprises the pro-oxidant activity of vitamin C [12,17]. Vitamin E Discovered at the beginning of the 1920s in vegetable oils such as that of wheat germ by Herbert Evans and Katherine Bishop, vitamin E is also denominated tocopherol or the anti sterile vitamin, due to its activity. Vitamin E is a group of methylated phenolic compounds known as tocopherols and toco trienols (a combination of the Greek words [birth] and [possess or car ry], which together mean "to carry a pregnancy"). Alpha-tocopherol is the most common of these and biologically that with the greatest vitaminic action. It is a lipophilic antioxi dant that is localized in the cell membranes whose absorption and transport are found to be very highly linked with that of lipids. In the mean diet of Spaniards, vegetable oils furnish 79% of the vitamin E that they consume . Vitamin E acts jointly and synergically with the mineral seleni um, another of the organisms antioxidants. Action: It has been proposed that in addition to its antioxidant function, vitamin E can per form a specific physicochemical function in the ordering of the lipic membranes, especially of phospholipids rich in arachidonic acid (thus acting as a membrane stabilizer) . Tocopherols act as intra- and extracellular liposoluble antioxidants within the body. It can reduce the formation of scars (stimu lating the curing of burns and wounds), could help in the treatment of acne, and is a poten tial treatment for diaper dermatitis and bee stings. Chemical structure: The chemical formula for vitamin E (C H O ) is utilized for designat29 50 2 ing a group of eight natural species (vitamers) of tocopherols and tocotrienols (,,, and ). They are essentials, given that the organism cannot synthesize them; therefore, their contribution is carried out through the diet in small amounts. For efficient absorption by the organism, these require the presence of fatty acids, bile, and lipolytic enzymes of the pan creas and intestinal mucosa . Chemical structure of the possible stereoisomers of the tocopherols and tocotrienols that make up the natu ral vitamin E.

This pro- vides healthy 162.5mg avalide fast delivery arrhythmia specialists, young cells to fill the gaping hole or to replace the injured cells order avalide 162.5mg otc blood pressure home remedies. Tumor Cell Division They dont stop because the brakes on cell division are not being used discount avalide 162.5 mg with mastercard blood pressure medication memory loss. The brakes are another chemi- cal made by each cell for itself, called pyruvic aldehyde. So, not only is there an accelerated multiplication of cells going on, but the brakes slowing them down are gone. Pyruvic aldehyde is susceptible to amines, much as car brakes are susceptible to drops of oil. But when massive amounts of amines appear in the cell, there may be no brakes on cell divi- sion for fifteen minutes at a time, followed by just one minute of pyruvic aldehyde, typical of a fast growing tumor. Some amines are produced naturally by our cells, perhaps to do exactly this release the brakes by combining with pyruvic aldehyde on a tight schedule. But for some reason the tumor cells can neither kill them, nor free themselves of them. The cells primitive solution to this impasse is to divide itself (release the brakes on cell divi- sion), so at least one of the two newly formed cells will escape and be free of the attacker, assuring survival. Like a fingernail you accidentally hit with a hammer, the nail will fall off eventu- ally and reveal a new one growing underneath. Tumor Cell Bacteria It is understandable now, why tumor cells are not able to do any work. That parasite then contrib- utes ortho-phospho-tyrosine to accelerate them into malignancy. Ordinarily when bacteria attack, either your cells or the bacteria win the battle. But if your cells win, the bacteria die and are digested by special little fortresses inside your cells called lysosomes. The virus genes now hidden amongst your own can be triggered by common chemicals (as anyone with chronic Herpes infection knows) to reproduce. Such an event is quite possible, even probable, when hordes of Clostridium bacteria have invaded your cells without killing them or being killed. Cell Defense Mechanisms Cells that are struggling for their lives call out for help. Ultimately, they call for self-destruction in a self-sacrificing way to protect you. Perhaps the metals arriving on the site destroy your white blood cells ability to find and home-in on 19 the infected cells. Perhaps the absence of germanium (the good, organic kind) suppresses immunity and does not let in- 20 terferon be made. Perhaps our white blood cells are smothered with ferritin or immobilized due to lanthanides (discussed in detail later). So for many reasons your cells cannot depend on your immune system to assist them. Their body temperature is H C C H often more than one degree C colder than normal! Oxidation means burning up by adding an oxygen atom or by subtracting an electron. Here is an example of oxidizing benzene (which looks simple, but is very difficult to do in your body). Sharing creates a strong bond between them, like two people holding hands tightly. Your body has the necessary enzyme to pry apart one of these strong bonds, and pull out an electron or insert an oxygen atom. The advantage gained is that the oxidized benzene atom is more soluble in water (namely urine) and can be excreted through the kidneys. If you live in a home with copper water pipes, the excess copper in your water is competing with the iron in your food. Other oxi- H C C H dizers like diamine oxidase, D- 23 amino acid oxidase, rhodi- zonic acid, and cytochrome C H C C H are also missing. Reduction, like oxidation, is strong chemistry, but in a cancer patient this mechanism is very 25 weak. Cell Mutations Meanwhile, as the cells are multiplying faster and faster, a sinister development takes place. The very act of mitosis (cell division) exposes the chromosomes to chemicals that might cause mutations. The protective nuclear membrane is temporar- ily gone, leaving the genes naked in the cell sap, called cyto- plasm. But in the Clostridium-infected cells, mitosis is going on much more frequently due to the overabundance of thiourea. The problem with constant mitosis is that it increases exposure of your genes to the hazards of mutagens (substances that cause mutations) in the cytoplasm. It at- tracts mutagens and carcinogens (these are chemicals specifi- cally known to cause mutations or tumors). Numerous small doses of a carcinogen, were 27,28 more effective than fewer large doses. In this respect, it was similar to the carcinogenic action of radiation: again, the smaller 29 the dose, the more effective it was. So that is why I advise people not to wear metal jewelry, to remove toxic tooth fillings, to change their metal water pipes to plastic, and avoid processed food (it has traces of dyes and antiseptic chemicals). Other attractive forces have already been studied: the liver attracts liver flukes, even if they are injected into a fish, far away from the liver near the tail; the flukes can somehow 27 Warburg, O. The attraction of certain metals, like thu- lium, gallium, technetium specifically to cancer sites has been the feature making bone scans possible. The attractive force between bacteria and white blood cells can be felt for long distances; it is de- 31 stroyed by heavy metals and fungus toxins. Perhaps some of these are not true forcesbut just an acci- dent of shape or chemistry, the way a kitchen sink drains and attracts water because of the hole in the base. Copper, cobalt, and vanadium are always there, detected by the Syncrometer; the others are often there. This also detoxifies them in the body, solu- bilizing them, so they can be excreted. After your sulfur is used up, the plain met- als remain in circulation and are attracted to the tiny hyperactive tissue where cell division is accelerated. They be- long to a special group of metals that are highly magnetic (paramagnetic), second only to iron. But they were so difficult to separate, one from an- other, that getting any one in pure form was rare indeed. There are 15 in all; although two other elements, yttrium and scan- dium, are often added to the group. They are rarely found as pollutants in processed foods, nor in drinking water with two exceptions.
The vaccine also led to modest reductions in pain and duration of zoster when it did occur avalide 162.5 mg low cost blood pressure newborn. The study also analyzed the incidence of post-herpetic pain buy avalide 162.5mg low cost hypertension kidney group 08755, a serious consequence that follows outbreaks of herpes zoster order avalide online pills arrhythmia kidney function. Post-herpetic neuralgia was reduced by two thirds in the vaccinated group of the study. The herpes zoster vaccine is a single dose immunization of a live attenuated varicella virus. The concentration of virus is more than 10 times that of the traditional varicella vaccine, therefore the two vaccines are not interchangeable. The immunization is not approved to treat zoster infection nor post-herpetic neuralgia. It is important to note that vaccination does not change the recommendations for routine cervical cancer screening. The vaccine will likely be given at age 11 to 12 years old in the pediatric population, along with the tetanus toxid plus diphtheria antigen with pertussis anti- gen (Tdap) booster. If the series of immunizations is interrupted, the next shot dose should be given as soon as possiblethe sequence does not need to be reinitiated. There is no data available to support the use of the vaccine in men or in women older than the age of 26 years, although trials are currently being carried out to assess efficacy of the vaccine in these groups. Pneumococcal disease causes an estimated 3,400 deaths each year in senior citizens older than the age of 65 years. The vaccine is 60 to 70% effective overall in the prevention of invasive pneumococcal disease, although it may be less effective in those with underlying serious illnesses. Antibody levels decrease over 5 to 10 years, but the nature of the relationship between antibody levels and the degree of protection is unclear. Published evidence confirms that the pneumococcal vaccine provides excellent protection against bacteremia in older adults, although other strategies may be necessary to combat nonbacteremic pneumonia. Persons with chronic disease include patients with chronic cardiovascular disease (e. In addition, persons aged 2 to 64 years who are living in environments or social settings in which the risk for invasive pneumococcal disease or its complica- tions is increased (e. A one-time revaccination is indicated for those vaccinated before age 65 years or for members of the highest-risk groups who were vaccinated more than 5 years earlier (asplenic or immunosuppressed patients or those with renal failure or who have had an organ transplant). The pneumococcal vaccine is administered intramuscularly or subcutaneously with 25g of each antigen per dose. The most common adverse reactions are pain, swelling, and erythema that occur at the site of injection in 30 to 50% of vaccinees. More systemic symptoms of fever and myalgias occur in approximately 1% of vaccine recipients. The vaccine is contraindicated in those with a moderate to severe acute illness and in those who have an allergic reaction to the vaccines components or who experienced previous adverse reactions to the vaccine. It may be administered simultaneously with the influenza vaccine but at another anatomic site. Approximately 60% of American adults aged 65 years and older have ever received the pneumococcal vaccine. National health objectives for 2010 include increasing the pneumococcal vaccination rate in elderly adults to more than 90%. To meet this goal, physicians need to seize opportunities in outpatient and inpatient settings. Studies have shown that 65% of those with severe pneumococcal disease had been hospitalized, and yet not vaccinated, within the past 3 to 5 years. With an increase in pneumococcal resistance to penicillin, it makes more sense than ever to try to prevent the diseases that are less responsive to antibiotics. Influenza and pneu- monia together are the sixth leading cause of death overall in the United States and the number one cause of death from infectious disease. Because of antigenic drift in the virus and waning immunity in the vaccine recipient, the vaccine needs to be given each fall. The inactivated vaccine usually includes two type A strains of influenza and one strain of type B. The exact com- position of the influenza vaccine is based on strains prevalent at the end of the pre- ceding flu season and outbreaks in other parts of the world. The effectiveness of the vaccine is partly based on the similarity of the vaccine to circulating strains. A new antigenic strain can result from antigenic shift, which leads to worldwide pandemics, the last of which occurred between 1968 and 1969. The overall efficacy is 70 to 90% in those younger than 65 years and 30 to 40% in frail elderly persons. Nonetheless, the vaccine is 80% effective in reducing death from complications of influenza among elderly patients. Other candidates include pregnant women who are beyond 20 weeks gestation during the flu season, all residents of long-term care facilities, and healthcare workers. A study conducted in 2000 showed that only 38% of healthcare workers were immunized. Studies have shown that employees are often the source of influenza spread in long- term care facilities. Local soreness at the immunization site occurs in approximately 20% of recipients. Systemic symptoms occur in < 1% of recipients, most often after the first influenza vaccination. Immunization is deferred until recovery in persons with moderate to severe acute illnesses. Patients with an egg allergy should be excluded from vac- cination in most circumstances. Our national health goals for 2010 target a 90% yearly influenza vaccination rate. In adults, studies have shown an efficacy statistically the same as the injectable influ- enza vaccine. It cannot be used in asthmatic patients, pregnant women, diabetic patients, or any other group that falls in a high-risk group for influenza. Similar to the injectable flu vaccine, it cannot be used in those with egg allergy. The recommendations also urged those with close contact to newborns, such as parents, grandparents, and healthcare workers be given the Tdap to decrease the chance of transmission to vulnerable newborns. The vaccine can be given in intervals as short as 2 years to those in close contact with newborns. The Tdap is category C, although pregnant women were excluded from prelicensure trials. Clostridium tetani is a slender, gram-positive, anaerobic rod that is sensitive to heat and cannot survive in oxygen. However, the bacteria produce a terminal spore that survives antiseptics and even autoclaving.
