The data shown in Tables 3 through 6 are original and have not been published yet cheap cialis black 800mg without prescription. It shows that even the concentration of vitamin C is lower in the edible portion in the shells report ed in Table 5 order 800mg cialis black with mastercard. Content of ascorbic acid in the shell of some fruits and vegetables Table 6 shows the values of ascorbic acid in some plant species used as flavoring for Mexi can dishes buy cialis black 800 mg on-line. In most cases the amount used for the preparation of food is very low and some times do not amount to more than 2% by weight of the end plate. However their presence in cooked food gives organoleptic properties suitable for the acceptance of it and especially the potential of the flavors of food. For this reason, it may partially destroyed in foods during processing, if exposed to air during storage or if treated with water. The addi tion of ascorbic acid as an antioxidant should be appropriately marked in the list of ingredi ents on the label of the final product Ascorbic acid and its salts are practically insoluble in lipids (fats), for this reason that is often used in the food industry as an antioxidant and preservative greasy foods, in order to avoid rancid. Their salts are usually used with a solubilizing agent (usually a monoglyceride) to improve its implementation. Sodium ascorbate is a sodium salt of ascorbic acid (vitamin C) and formula C H NaO. This form is used in the food industry for their functions antiseptic, antioxidants,6 7 6 and preservatives. Ascorbyl palmitate is an ester formed by ascorbic acid (vitamin C) and palmitic acid creating a liposoluble form of vitamin C. It is wrong to think that is a natural antioxidant Use as a preservative Is usually used as a food preservative and as antioxidant in the food industry, a typical case is found as a bread improver additive. In industry collecting fruit prevents the color oxida tive change known browning. Is often added to foods treated with nitrite in order to reduce the generation of nitrosamines (a carcinogen), so commonly found in sausages and cold cuts. Ascorbic acid and its sodium, potassium and calcium salts are used widely as antioxidants and additives. These compounds are soluble in water, so that fats do not protect against oxi dation. For this purpose may be used ascorbic acid esters with fat soluble long chain fatty acids (palmitate and ascorbyl stearate). Signs and symptoms A frank deficiency of vitamin C causes scurvy, a disease characterized by multiple hemorrhag es. The diagnosis of scurvy, is achieved by testing plasma ascorbic acid, low concentration indicates low levels in tissues. It is generally accepted that ascorbic acid concentration in the layer of coa gulated lymph (20-53 ug/10 leukocytes) is the most reliable indicator of nutritional status re8 garding vitamin C and its concentration in tissues. Deficiencies secondary and association with other diseases Severe deficiency of vitamin C leads to Scurvy. By deficiency of collagen, the wounds do not heal scars and wounds of previous rupture and may lead to secondary infections. Neurotic disorders are common, consisting of hyste ria and depression, followed by decreased psychomotor activity. In addition to "rebound scurvy," gastric intolerance and kidney, its use decreases the cobalamin (vitamin B ), a substance synthesized by the body. The daily requirement in an adult male is 90 mg/d and a woman of 75 mg/d (mg/day), although there are always situations where it is necessary to increase the dose of vitamin A through supplementation. Anemia by Vitamin C Deficiency Anemia of vitamin C Deficiency is a rare type of anemia that is caused by a severe and very pro longed lack of vitamin C. In this type of anemia, the bone marrow produces small red blood cells (microcytosis). This deficiency is diagnosed by measuring the values of vitamin C in white blood cells. However this method quantifies all the forms of the vitamin C present in the sample, and even it detects an epimer of ascorbic acid, the eritorbic acid or isoascorbic acid. The samples of vitamin C saturation are used to establish the defi ciency of ascorbate in tissue and are useful to confirm the diagnostic of scurvy when the pa tient has a normal absorption (Engelfried, 1944). It has been described 3 types of tests to determine the tissue saturation, the first 2 are easy to make but they dont cover the problem on totally, the third test is complicated and its only useful in research work listed below: a. Measurement of blood levels with and without a test sample: The vitamin C in the plasma is not found doing a metabolic function; it is rather in a transit from one tissue to another. Its lost or decrease does not indicates the intracellular sta tus of this vitamin. A well-nourish adult with a free acid ascorbic diet decreases his serum levels of acid to cero in about 6 weeks; however only after many weeks of more deprivation the scurvy symptoms appears. So that for this reason the scurvy patients have low levels of ascorbic acid in the plasma.

The diagnosis of cancer in pathology is mainly based on the morphology of tissues and cells trusted cialis black 800mg. The immunological reaction that takes place with this technique has remarkable sensitivity and specificity and it is applicable to routinely processed tissues cialis black 800mg sale, including fixed tissues discount cialis black 800 mg amex. A great advantage of immunohistochemistry is the fact that we can simultaneously visualize the morphology of the cells and the immunostaining, so that we can locate the antigen we are detecting, in a particular subcellular localization or in a specific subtype of cells. Another advantage of the technique is that it is applicable to several types of material including tissue sections and cytological specimens [Chess & Hajdu, 1986]. At present, it is thought that their utility depends on the use of a panel of markers that include various combinations of them [Zafon et al. Batistatou et al [2008] found a negative correlation between E-cadherin and dysadherin expression and the tumor size. Correlation (+ positive, - negative, 0 no correlation) between molecular markers and papillary thyroid microcarcinoma features. Papillary Thyroid Microcarcinoma Do Classical Staging Systems Need to Be Changed? Additionally, the role of age, as the paradigm of prognostic factors, remains to be established. Older age is especially significant in patients with advanced tumors [Pelizzo et al. However, once again, though articles recognize the age factor, most of them are retrospective studies that include cases without current standardized therapeutic protocols. Moreover, few reports specifically analyze the behavior of thyroid cancer in the elderly. The authors found that older age was an important risk factor for overall survival. Furthermore, investigators showed that the probability of survival changed significantly according to the decade in which the patient was treated. They concluded that one important difference with respect to younger subjects was the delay in the diagnosis. It is assumed that older subjects have tumors with a higher percentage of histological types with less favorable prognosis [Hundahl et al. Other factors have been proposed such as the sexual hormone status and the impaired immune response, which accompanies older individuals [Haymart, 2009a]. Accordingly, it appears that thyroid cancer in the elderly and in younger patients could have a different behavior [Biliotti et al, 2006]. They found that only an increased age at diagnosis predicted decreased disease-specific survival. However, age was not related with multifocality, bilaterality and extrathyroid extension, risk factors shown to increase recurrences. The same authors also showed that there was no correlation between the duration of the disease-free interval and the age of patients [2008]. Another study reported that patients with lymph node metastasis were younger than those without lymph node metastases [Chung et al. On the contrary, some reports suggest that younger age could be a worse prognostic factor. To date, the clinical significance of many of these variables is yet to be established. As a consequence, there is no agreement about the optimal treatment of smaller tumors [Kk et al, 2007]. Whereas some authors argue for an aggressive approach, others suggest that no further treatment is needed after lobectomy or thyroidectomy. Moreover, some even propose observation, without surgical treatment [Ito et al, 2003]. Papillary thyroid carcinoma and microcarcinoma: is there a need to distinguish the two?
