Cure Tooth Decay Heal And Prevent Cavities With Nutrition

About seven months ago, I walked out of a dental office with a pretty serious quote for dental work that was needed to be done on 8 different cavities they found in my teeth. I was confused. I eat a pretty good diet. How could my teeth have cavities? I brush and I floss every day. How could this happen? I told my dentist that I had heard about the â€Å"remineralization† of teeth and even curing tooth decay and cavities with certain staples in your diet, and asked him his opinion on the subject. Of course, like any conventional dentist, he had never heard of it. I’m pretty sure he even offered fluoride treatments at that point. After that, I stopped asking questions, scheduled an appointment to have all of the cavities filled, and left somewhat upset and unsatisfied. When I got home, I began researching natural ways to heal your teeth. I read the book â€Å"Cure Tooth Decay: Heal Prevent Cavities with Nutrition† by Ramiel Nagel, and learned about healing and remineralization of teeth with a good diet, and my mind was completely blown. I can actually heal my own cavities without spending thousands at the dentist? I can actually heal my cavities and remineralize my teeth with a proper diet? No more needles or drills in my mouth? Count me in! To completely understand how to heal your own cavities, we need to look at what causes tooth decay. Lack of Nutrition is the Root of Tooth Decay Dr. Weston A.

LDH Purification lab Report free essay sample

Abstract The enzyme lactate dehydrogenase (LDH) catalyzes the last step of anaerobic glycolysis that is important for the normal function of the body. Purification of LDH is essential to understand its structure and function. The purpose of this experiment was to extract and purify LDH enzyme from chicken muscle tissue using a variety of various. Analytical methods such as activity and protein assay were employed to determine the presence and purity of LDH. The cells were initially disrupted and proteins were solubilized. LDH was purified from the ammonium sulfate precipitated protein mixture by affinity chromatography and its activity was studied by spectrophotometric determination of NADH at 340 nm. From Pierce BCA assay of crude homogenate, initial protein concentration was shown to be 100 mg/ml. The final protein concentration of the pooled affinity sample was shown to be 0.2 mg/ml. It was found that the total specific activity of LDH was 58.5  µmol/min/mg, and yield of 0. 6%. Even though we were successful in purifying LDH enzyme, further steps can be taken to increase the yield. Materials and Methods Cell Lysis and Extraction of LDH: Approximately 40 g of minced chicken breast meat (40.327 g) is blended with 75ml cold extraction buffer in four 30-seconds bursts for homogenation of the muscle tissue. The extraction buffer contained 10mM Tris-HCl (pH-7.4), 1mM 2-Mercaptoethanol, 1mM Phenylmethylsulfonylflouride (PMSF), 1mM Ethylene diamine tetraacetic acid (EDTA). The homogenization procedure was carried out in the cold room to prevent the denaturation of proteins. The homogenate was centrifuged at 15,000 rpm for 20 minutes at 40 C. The supernatant was filtered through two layers of cheesecloth to remove lipids from the supernatant. The total volume was noted and three 0.5 ml aliquots (crude extract) were stored at -200 C. Ammonium sulfate precipitation: 60% ammonium sulfate concentration was used to precipitate proteins. 0.39 g of ammonium sulfate per ml of the  supernatant was added gradually to the supernatant for 15-20 min with continuous gentle stirring at 40 C. The mixture was centrifuged for 20 minutes at 15,000 rpm at 40 C. The supernatant was discarded and the pellet was stored at -200 C. Dialysis: Ammonium precipitation leads to high concentration of salts in protein mixture that can interfere with further purification steps. In order to remove excess salts, dialysis was performed. The pellet was suspended in Tris-PMSF buffer (10 mM Tris-HCl, pH 8.6, 0.5 mM 2-Mercaptoethanol, and 1mM ratio of EDTA) and mixed very gently until it dissolved at 40 C. Volume of 4ml protein mixture was added in the dialysis tubing and incubated twice overnight with two 1L buffer changes (Same buffer as extraction buffer that was used for cell lysis). After two incubations, protein mixture was resuspended gently and centrifuged for 10 minutes at 15,000rpm at 40C. Pellet was discarded, total volume of supernatant was noted and three 0.1 ml aliquots were collected. Affinity Chromatography: Cibarcon Blue column was used to separate LDH from the other proteins. 5ml fractions were collected in thirteen test tubes. Column was first rinsed with Tris-PMSF buffer followed by addition of protein mixture. Then, 10ml NAD Buffer (10mM Tris-HCl pH-8.6, 0.5mM 2-Mercaptoethanol, 1mM Lithium acetate and 1mM NAD+) was added followed by 10ml NADH (10mM Tis-HCL PH 8.6, 1mM NADH and 0.5mM 2-Mercaptoethanol). Between each steps, column was washed with 10ml Tris-PMSF Buffer. Each fraction was subjected to absorbance reading of 280nm. For absorbance above 1.5nm, 1:10 dilutions were carried out. Activity Assay: We used LDH Enzyme assay to measure the amount of LDH activity in our protein mixture. LDH catalyzes the conversion of lactate to pyruvate and NAD+ to NADH. The NADH can be determined spectrophotometrically at 340 nm. The LDH assay was performed in the crude homogenate, desalted fraction and six peak fractions from the Cibacron blue column. A cocktail solution was prepared by mixing lactate stock solution (120 mM lithium lactate, 10 mM Tris-HCl; pH 8.6), NAD+ stock solution (12 mM NAD+, 10 mM Tris HCl; pH 8.6) and bicarbonate stock solution (18 mM NaHCO3, 0.5 M NaCl)  in the ratio of 6:4:2 in cuvette. 10 microliters of the sample is then added and the assay absorption is measured at 340nm. If absorbance was above 1.5, samples were diluted. Protein Assay: The Pierce BCA Protein Assay (Thermo Scientific) is a detergent-compatible formulation based on bicinchoninic acid (BCA) for the colorimetric detection and quantitation of total protein concentration. A series of standard solution of Bovine Serum Albumin (BSA) ranging from 0-2000  µg/ml was prepared from a stock solution of 2 mg/ml BSA. 25ul of diluted crude (1:500, 1:250), desalted (1:100, 1:50), and 6 peak fractions from cibarcon blue column (1:10, 1:5) were loaded in microplate along with 175ul of BCA working reagent. Microplate was incubated for 30min at 370C and then the absorbance was measured at 562nm. Results/Discussion The purpose of this experiment was to extract and purify LDH enzyme from chicken muscle tissue using a variety of techniques including homogenization, ammonium sulfate precipitation, dialysis, and affinity chromatography. Activity and Protein assay were used to track the overall amount of LDH present in the samples. Crude Extraction: Chicken muscle tissue was homogenized in a blender with cold extraction buffer in order to lyse cells, releasing LDH into slurry of tissue components. Centrifugation separated membranes, nuclei, and other large cellular components to a pellet leaving a supernatant of crude product. Controlling temperature was a major consideration after homogenization since not only did this step releases proteins like LDH from the cell, but it also releases proteases that can now interact to degrade the LDH. Keeping samples on ice, pre-cooling the buffer, and avoiding excess kinetic energy through conservative blending were methods used to minimize activity of these proteases. After filtration through cheesecloth, our final volume of crude homogenate sample 74ml, much more volume than expected. Addition of more than 75ml of buffer volume could have increased the volume. Other possible explanation is that more solid components such as fats were present in the sample and hence, more than 20 minutes of centrifugation was  required. Desalted Sample: 60% ammonium sulfate is added to the crude extract that precipitates LDH proteins. The resulting 40% pellet theoretically contains most of the original LDH, which is re-suspended in very less volume (4ml) to create a more concentrated sample. This process leads to high concentration of salts in protein mixture that can interfere with subsequent purification steps. 4ml protein mixture underwent dialysis procedure that removes excess salts and our final volume after dialysis was 6ml. One possible explanation for increase in our volume could be that extraction buffer got mixed with protein mixture either due to tubing leaking or tubing clips not being properly tightened. Affinity Chromatography: Cibacron Blue column is an affinity column, which is specific to dehydrogenase type proteins, due to a compound structurally similar to NADH being attached covalently attached to the column. 13 fractions were collected and absorbance was measured at 280nm to check presence of LDH protein in the fractions. 1:10 dilution was performed if absorbance reading was above 1.5nm since it spectrophoretically indicates saturation and less than 1% light reaching the detector. During the addition of protein mixture (fraction# 4), high absorbance reading of 10nm was obtained (Fig.1). This could be due to lot of non-dehydrogenase-type proteins present in our sample that got eluted first during affinity chromatography. Second peak was seen after NAD+ was added since NAD solution results in the removal of the loosely bound protein. Third peak was seen after NADH was added since NADH solution results in release of maximum LDH proteins (Fig. 1). Enzyme Activity Assay: The LDH activity was measured spectrophotometrically by measuring the absorbance of NADH at 340 nm. Three peak fractions were selected for this assay based on their absorbance values obtained after adding NAD+ (fraction# 6, 7, 8) and other three after adding NADH in the affinity chromatography step (fraction# 10,11,12). A huge activity of 141umol/min/ml was seen at fraction# 7(PF1) which indicated that we had lot of proteins present in our sample. Second peak activity was seen at fraction #10 indicating that more LDH proteins is present in this fraction than in fraction# 11 (PF2) (fig.1). Based on this information, we selected fraction #10 as for our protein assay. Desalted showed highest activity among all the samples (Table1) possible due to errors occurring during dialysis explained previously. Figure 1. Absorbance readings of elutes obtained from affinity chromatography with LDH activity for 6 peak fractions. The desalted fraction was loaded to the Cibarcon blue column and proteins were eluted with Tris-PMSF, NAD+ and NADH wash subsequently. The absorbance at 280 nm of elutes were measured after each collected fractions. The LDH activity was calculated from the absorbance values obtained at 340nm. Protein Assay: We used BCA Pierce Assay to determine protein concentrations in our protein mixture. BSA standard curve was created for series of dilutions ranging from 0-2000  µg/ml and linear graph equation was used to calculate protein concentrations for the samples (Table 1). Based on Table 1, with each subsequent purification step, protein concentration decreases as sample become more concentrated with only LDH protein. Specific activity should increase and total activity should decrease with every purification step as samples get less and less diluted. Similar trend was observed in our study as well. However, exception is PF1 that has higher specific activity due to high activity suggesting more loosely bound proteins were eluted after NAD+ was added.

madonna and child Essay Giovanni Bellini was born in 1426 1516. He was born in Venice, Italy. His father, Jacopo was also a painter. Giovanni more than likely began his career as an assistant in their fathers workshop. In hisfirst years as an artist Bellini was strongly influenced by his brother-in-law, Andrea Mantegna, from who he took a sculptures figure style. Giovanni Bellini was the founder of founder of the Venetian school of painting. He raised Venice to a centre of renaissance art that rivalled Florence and Rome. I will discuss two of his paintings further on in the essay. Madonna with the child (Greek Madonna) Madonna of the Meadow (Madonna del Prato) Madonna with the Child (Greek Madonna) 1460-64, Bellini Rafaello Santi was born in Urbane on good Friday 6th Aril 1483. His father was a painter and poet and worked for Frederica da Montefelto who was of the most famous princes and art patrons of the early Italian renaissance . Raphael helped his father in his studio from an early age. This is wh ere he is believed to have learned about art. His father died in 1494 and in 1504, Raphael moved to Florence and lived there for four years. He studied works by Leonardo da Vinci and Michelangelo here which inspired him even more. It was in Florence he began his series of Madonnas. I will talk about two of his Madonna paintings later. The Small Cowper Madonna Raphael c1505 In this essay I am going to discuss Raphaels and Bellinis approach to the theme Madonna and child. Both Bellini and Raphael painted many versions of the Madonna and child, both viewed this theme as a religious one however we can see that both portrayed the Madonna and child differently. Raphael painted Madonna and childs relationship as a warm and loving one. Be

AIDS - Whats New Essays - HIVAIDS, HIV, , Term Papers

AIDS - What's new ? ------------------- Is the message getting through? We already know enough about AIDS to prevent its spread, but ignorance, complacency, fear and bigotry continue to stop many from taking adequate precautions. We know enough about how the infection is transmitted to protect ourselves from it without resorting to such extremes as mandatory testing, enforced quarantine or total celibacy. But too few people are heeding the AIDS message. Perhaps many simply don't like or want to believe what they hear, preferring to think that AIDS "can't happen to them." Experts repeatedly remind us that infective agents do not discriminate, but can infect any and everyone. Like other communicable diseases, AIDS can strike anyone. It is not necessarily confined to a few high-risk groups. We must all protect ourselves from this infection and teach our children about it in time to take effective precautions. Given the right measures, no one need get AIDS. The pandemic continues: ----------------------- Many of us have forgotten about the virulence of widespread epidemics, such as the 1917/18 influenza pandemic which killed over 21 million people, including 50,000 Canadians. Having been lulled into false security by modern antibiotics and vaccines about our ability to conquer infections, the Western world was ill prepared to cope with the advent of AIDS in 1981. (Retro- spective studies now put the first reported U.S. case of AIDS as far back as 1968.) The arrival of a new and lethal virus caught us off guard. Research suggests that the agent responsible for AIDS probably dates from the 1950s, with a chance infection of humans by a modified Simian virus found in African green monkeys. Whatever its origins, scientists surmise that the disease spread from Africa to the Caribbean and Europe, then to the U.S. Current estimates are that 1.5 to 2 million Americans are now probably HIV carriers, with higher numbers in Central Africa and parts of the Caribbean. Recapping AIDS - the facts: --------------------------- AIDS is an insidious, often fatal but less contagious disease than measles, chicken pox or hepatitis B. AIDS is thought to be caused primarily by a virus that invades white blood cells (lymphocytes) - especially T4-lymphocytes or T-helper cells - and certain other body cells, including the brain. In 1983 and 1984, French and U.S. researchers independently identified the virus believed to cause AIDS as an unusual type of slow-acting retrovirus now called "human immunodeficiency virus" or HIV. Like other viruses, HIV is basically a tiny package of genes. But being a retrovirus, it has the rare capacity to copy and insert its genes right into a human cell's own chromosomes (DNA). Once inside a human host cell the retrovirus uses its own enzyme, reverse transcriptase, to copy its genetic code into a DNA molecule which is then incorporated into the host's DNA. The virus becomes an integral part of the person's body, and is subject to control mechanisms by which it can be switched "on" or "off". But the viral DNA may sit hidden and inactive within human cells for years, until some trigger stimulates it to replicate. Thus HIV may not produce illness until its genes are "turned on" five, ten, fifteen or perhaps more years after the initial infection. During the latent period, HIV carriers who harbour the virus without any sign of illness can unknowingly infect others. On average, the dormant virus seems to be triggered into action three to six years after first invading human cells. When switched on, viral replication may speed along, producing new viruses that destroy fresh lymphocytes. As viral replication spreads, the lymphocyte destruction virtually sabotages the entire immune system. In essence, HIV viruses do not kill people, they merely render the immune system defenceless against other "opportunistic: infections, e.g. yeast invasions, toxoplasmosis, cytomegalovirus and Epstein Barr infections, massive herpes infections, special forms of pneumonia (Pneumocystis carinii - the killer in half of all AIDS patients), and otherwise rare malignant tumours (such as Kaposi's sarcoma.) Cofactors may play a crucial contributory role: ----------------------------------------------- What prompts the dormant viral genes suddenly to burst into action and start destroying the immune system is one os the central unsolved challenges about AIDS. Some scientists speculate that HIV replication may

Economic growth in Australia since 2000 Australia has been standing out among OECD countries due to its sound economic policies. However, the slow growth of Australia’s economy is because of the financial crisis of 2008-2009. Australia is making efforts for the adjustment in the structural changes that is due to the commodity bang (OECD Economic Surveys Australia, 2012). The recent mining boom initiated in the year 2000 that led to the esca lating cost of commodities linked with mining. The following figure illustrates the rise in the non-rural commodity prices: Fig-4: Non-rural commodity prices: Source: Index of Commodity Prices, Reserve Bank of Australia as cited in Pham et.al, 2013, p.2 The mining boom has affected the Australian economy in some way or the other.Advertising We will write a custom essay sample on Sustaining Australias rate of economic growth specifically for you for only $16.05 $11/page Learn More The export companies as well as the struggling import businesses have made the Australian dollar to trim down the price competitiveness in the international market. â€Å"The Reserve Bank of Australia declared that the mining- related commodity prices peaked in August 2011, and are now down by around 23 percent from this peak.

Figure 4: The following chart shows Australia’s Gross Domestic product growth Source: ABS Cat. No. 5206.0, Australian National Accounts as cited in Pham et.al, 2013, p. 3 Sustaining economic growth in future The constant uninterrupted economic growth of Australia for past two decades will sustain in two conditions in near future: 1) the potency and span of the resources boom; and 2) productivity growth. Australia’s income growth in near future will depend upon maintaining a scenario that involves returning productivity growth to its historical standards, maintaining the terms of trade bringing all the advanced ventures and three-quarters of the partially developed projects to the stream. However, that too would ensure only 3.7 percent income growth as compared to the standard growth of 4.1 in the past. But the w orst-case scenario is draws attention that suggests that the terms of trade is leaning toward their long term average there is likely to be only two-thirds of advanced capital projects and one-third of the less advanced projects coming to realization and suggests no development in the current productivity growth. This sobering scenario may be threatening to the Australian income growth of 0.5 percent till 2017. Figure 5: Source: Taylor et.al, 2013, p.4 Mining and non-mining Sectors Conventionally, the economy of Australia can be divided into two-speed economy. One is a flourishing resources segment and the other comprises of all other gradually developing segments. However, it is wise to see Australia’s economy divided into four parts. The following figure illustrates the four sectors with respect to their link with the resources. Figure 6: Source: Taylor, et.al,2013,p.5 Resources sectors: Enforce capital productivity for successful investment According to Shann (2012), the speedy growth yet decreasing capital productivity in the resource sector has been evident in Australia’s economy. The lowest ridge in the scenarios for future income escalation is suggestive that future investment in the resource sector will surpass the previvious levels of income growth. There is an urgent need to get the capital productivity right that may lead to the prospective income growth (as cited in Taylor et. al, 2013). To capture the gains, it is necessary that the individual companies and the policy makers work together. Government is required to provide support through providing environmental approvals, development of the infrastructure, and enhancing industrial relations so that there can be balance maintained between growth and other social good. Resource rider sectors: Need to improve efficiency The other sectors like transport and professional services have also been affected by the mining energy boom; however, these have witnessed decrease in productivity. â€Å"These sectors attracted the vast majority of the overall economy’s increase in labor from 2005 to 201, but the contribution of labour productivity to sector output fell to zero during this period† (Taylor et.al 2012,p.6). It is important that new ways and more integrated cross-sector approach in resource productivity should be incorporated to make the infrastructure development more cost efficient. Local services: committing again to microeconomic reform Local services like retail trade and telecommunications do not exhibit any major impact of the resources boom. These sectors have shown solid productivity growth of A$49 billion to the overall income growth in 2005-2011. It is important that efforts from the individual companies in the form of innovative operating representation and government’s endeavor to rationalize regulation, promote improvement and encourage competitive markets can boost productivity. For this purpose, Australia needs to adopt the mi croeconomic reform as it did in 1990s. Manufacturing: Creating the base for long-term competitiveness Australia has seen continuing erosion in manufacturing productivity and employment. There has been a significant decrease in the capital productivity in the past six years except for the limited counterbalance created by the labor productivity. Improvement in the manufacturing sector can be derived through further cost efficiencies in the subsectors that contend mainly on price, enhancing labour mobility in the manufacturing sector along with a strong and facilitating ecosystem for bringing novelty in manufacturing. These measures can bring extra national income of about A$ 90 billion a year and sustain the historic scenario by 2017(Taylor et.al, 2013). Outlook It is difficult to state with surety when the climax will come about and the speed at which the mining investment will descend as a share of GDP. The decisive factors will be the actions taken on the uncommitted ventures and the speed of development in the existing projects along with the degree and features of the added overruns. However, there is a possibility of increased mining investment for quite some time as a huge bulk of work is still in progress. With the mining investment becoming weaker, it will enter upon the set phase of mining boom. The exports will rise as a reaction to the investment that has been taken on. The manifested growth in the resources like iron ore, coal and LNG exports for some time is suggestive of the further growth in these resources from 2015. Figure 7: Source: Kent, 2013, Para 14 Conclusion The trend in the mining investment reflects that the economic growth will be a little less around and will pick up later in 2014.As the growth rate of sectors other than the resources sector is gradual, it is better to observe the signs for some more time (Kent, 2013).

The Effects of Competition, Predation and Disturbance Essay

The Effects of Competition, Predation and Disturbance - Essay Example The predator is the population that attacks and hunts the prey population for survival. The process of predation ultimately leads to the death of the prey in cases which are either intentionally or unintentionally and also directly or indirectly undertaken by the predator. The said process then can be defined as consumption of the prey population. There are different types of predation that are undertaken by the four types of predators namely the true predators, the grazers, the parasitoids and the parasites. The said classification is based on the type of action wherein the process of predation is completed. The process of predation can result in different effects which can either be beneficial or detrimental to the prey population, predator population and the ecosystem in general. One of the most important effects of predation is the maintenance of balance between species population by prevention of the domination of a single type of organism in a community. The said process can be attributed to the action undertaken by the predators. For that matter, predation can be beneficial to the predators. On the other hand, the prey population is the main group that can achieve the detrimental effects of the process of predation. Although this is the case, due to the interactions of the different organisms in an ecosystem as exemplified by the food web and food chain, an organism can be a prey of a larger species while at the same time a predator of a smaller species. This process of interaction is the main cause for the achievement of the ultimate balance in the ecosystem. One of the ways to better understand the predator-prey interaction is through the use of the Lotka-Volterra model.
