In general, estrogen modulates the activity of target cells by binding to special cellular sites called and estrogen receptors. Phytoestrogens, which include isoflavones, are a broad group of plant-derived compounds that have selective estrogenic actions. They have an impact on these and receptors but not as strongly as real estrogen.2 In some tissue, they stimulate an estrogenic response agonistic activity in others, they inhibit the estrogenic effect antagonistic activity ; .3 They act as "natural" selective estrogen receptor modulators SERMs ; . SERMs, such as raloxifene and tamoxifen, are engineered drugs that possess a specific action similar to that of estrogen.4.

Effect on lipoprotein a ; in 6 other studies, 20, 50, 55, nor did soy protein that contained isoflavones.20, 31, 32, 36. The isoflavones play diverse roles in the plant-microbe interactions of the Papilionoideae. Isoflavones function as antibiotics as well as precursors for defense-related phytoalexins. They also serve as signal molecules in the induction of microbial genes involved in soybean Glycine max ; nodulation. Although isoflavones are normally present at relatively low levels in mature soybean tissues, their accumulation is strongly induced in response to pathogen attack or defense elicitors. Isoflavonne synthase IFS ; is a key enzyme for the formation of the isoflavones. Subramanian et al. pp. 13451353 ; show that the silencing of both copies of IFS genes in roots initiated from soybean cotyledons leads to the effective spread of silencing throughout the nontransformed cotyledon tissues. Distal silencing was established within 5 d of transformation and was highly efficient for a 3- to 4-d period, after which it faded. Distal silencing effected a nearly complete suppression of mRNA accumulation for both the IFS1 and IFS2 genes and of isoflavone production induced by wounding or treatment with the cell wall glucan elicitor from Phytophthora sojae. Preformed isoflavone conjugates were not reduced in distal tissues, suggesting little turnover of these stored isoflavone pools. Silencing of IFS led to enhanced susceptibility to P. sojae. The soybean cotyledon system may prove to be a convenient and effective system for the functional analysis of other plant genes through gene silencing. acid serves as a pathogenicity factor during Sclerotinia infection. Direct application of oxalic acid to stem or leaf tissue causes tissue injury and wilting, similar to plant responses to fungal infection by S. sclerotiorum. Mutant isolates of S. sclerotiorum, deficient in oxalic acid production, are not pathogenic on bean Phaseolus vulgaris ; , but revertants became pathogenic once they regain the ability to produce oxalic acid. Oxalic acid may aid in fungal infection through a number of proposed routes, including the facilitation of cell wall-degrading enzyme activity, through pH-mediated tissue damage, or via sequestration of Ca21 ions. There is also evidence that oxalic acid can directly suppress the oxidative burst associated with the detection of pathogens by plants and disturb guard cell function during infection by S. sclerotiorum by inducing stomatal opening and inhibiting abscisic acid ABA ; induced stomatal closure. Oxalate oxidase OO ; has received considerable attention for its possible utility in plant defense. OO catalyzes the degradation of oxalic acid to produce carbon dioxide and hydrogen peroxide. It has been proposed that through the production of hydrogen peroxide, OO may cause cross-linking of plant cell wall proteins at the site of infection or play a role in the plant hypersensitive response. Livingstone et al. pp. 1354 1362 ; report that the size of S. minorinduced lesions were reduced by 75% to 97% in OO-transformed peanut plants, providing evidence that OO confers enhanced resistance to Sclerotinia blight in peanut. secretions, it is generally assumed that their effect on growth is mainly due to removal of phloem sap from their host plants. Kinematic studies offer a powerful tool for assessing the fluxes and deposition rates that sustain the growth of plant organs. Although kinematic studies have previously been used to study the effects of a wide variety of abiotic stresses on growth, Girousse et al. pp. 14741484 ; provide the first kinematic study of a biotic stress, namely pea aphid infestation of alfalfa. They report that severe short-term aphid infestation induces a strong and synchronized reduction in elongation and in water and carbon deposition. Reduced nitrogen contents were observed in some parts of the infested stems, especially in the apex. This suggests that aphid infestation converts the shoot apex, normally a sink tissue, into a source tissue. Because aphid infestation reduced longitudinal elongation 1.4 times more than radial expansion, and in a manner similar to mechanical stimulation, the authors speculate that aphid infestation stress may also involve a thigmomorphogenic component and isoniazid. Sub 2-value has significantly shortened as a result of the administration of the anabolic isoflavone from 03 days to 23 days ; which is also indicative of the protein incorporation. The statin guidelines list as high risk individuals: frail elderly over age 80 ; who have small body frames, patients with multisystem disease, patients following surgery, patients taking multiple drugs, patients consuming more than a quart of grapefruit juice daily, and patients who abuse alcohol and vasodilan, for instance, isoflavones men. Many chemicals that induce illegitimate recombination of MLL gene are also inhibitors of DNA topoisomerase II topo II ; , which functions in maintaining the fidelity of gene transcription, DNA replication and recombination by directing DNA unwinding and religation. Common topo II inhibitors include benzene metabolites, isoflavones, flavonoids, certain herbal medicines, pesticides, and some cancer chemotherapeutics [9]. Maternal dietary consumption of topo II inhibitors has been associated with increased risk to IAL in at least two case-control studies [8, 10]. Furthermore, cancer chemotherapeutics such as the epipodophyllotoxins and including etoposide ; that target topo II have been associated with increased risk of treatment-related leukemias secondary to chemotherapy [7, 19]. As in IAL, a large proportion of the chemotherapy. It is only administered by qualified healthcare professionals and ketorolac.

Similarly, the low-density lipoprotein cholesterol LDLC ; concentrations are much lower in monkeys fed Soy + ; compared with Soy - ; .5, 6 We were inclined to interpret those observations as evidence that the lipid lowering property of soy protein is related in a major way to the presence of the soy phytoestrogens or isoflavones. We recently completed a study that contradicts that theory, since we have been unable to restore the plasma Figure 1 lipid lowering effect of Soy - ; by adding back its isoflavones. Further evidence against our initial interpretation are several clinical reports suggesting that plasma lipid concentrations of women are consistently lowered by feeding isolated soy protein with isoflavones but not by feeding pills of isolated soy isoflavones.7 The cardiovascular beneficial components of soy protein remain an enigma and will SOYAND SOY be the subject of Effects of two doses of Raloxifene Lo Raloxifene: dose equivalent to 60 mg woman day, Hi PHYTOESTROintensive research Raloxifene: dose equivalent to 300 mg woman day ; compared to conjugated equine estrogens GENS over the next few CEE: dose equivalent to 0.625 mg woman day ; on cardiovascular endpoints in cynomolgus Some plants, primaryears not only by monkeys.

Miracle Foods" Need Further Study Soy: Scientists believe that compounds in soy called isoflavones bind to estrogen receptors in breast cells. Thus, they block human estrogen from entering cells and spurring tumor formation. But research results on the effects of jsoflavone supplements on breast cell growth and cancer risk have been conflicting. Since it is not known whether large doses of soy are protective or harmful for women at high risk for estrogen-dependent breast cancer, it's best to eat moderate amounts of soy foods and avoid isoflaovne supplements. Flaxseed: Flax provides lignans beneficial plant estrogens ; and alpha-linolenic acid an omega-3 fatty acid ; , both of which may offer breast cancer protection. In animal and human studies, diets containing flaxseed reduced breast tumor growth. According to Dr. Lilian Thompson, a flax expert from the University of Toronto, "Most people can eat flaxseed in moderation - about one tablespoon of ground flax a day - as part of a healthy diet. However, until clinical studies are completed, women with hormone-dependent breast cancer and those taking drugs like tamoxifen should limit or avoid eating large amounts of flax. Assigned a value of one-half the detection limit. Average 4-methylumbelliferone recovery from hydrolyzed 4-methylumbelliferone glucuronide was 80%. Each batch included 20 samples, consisting of 10 pairs i.e., samples from nights 1 and 2 ; of overnight urines. Laboratory staff were blinded to all characteristics of each aliquot. Two previously unthawed aliquots of an overnight urine pool from female donors were included in each batch for quality control purposes; mean urinary daidzein, genistein, ODMA, and equol in pool samples were 4.9, 3.2, 0.6, and 0.2 nmol ml, respectively. Based on the results for the quality control aliquots, the intra-run CV values were 5% for all compounds. Inter-run CV values for daidzein, genistein, ODMA, and equol were 12.9%, 22.4% 16.7%, and 14.8%, respectively. Results for ODMA excretion and equol excretion on day 2 were unavailable for two women and one woman, respectively, due to interfering peaks on the chromatogram; data on the other analytes were available for these women. Cr Analysis. Urinary Cr concentrations were measured on aliquots from all overnight urine samples based on a kinetic modification of the Jaffe reaction using the Roche Reagent for Cr Roche Diagnostic Systems, Nutley, NJ ; on a Roche Cobas Mira Plus chemistry analyzer, after first diluting the samples 1: 50 with distilled water. The assay was linear to 20 mg dl, and the intra- and inter-assay CVs were between 1% and 2%. Data Analyses. Urinary isoflavone data calculated as nmol mg Cr ; and isoflavone intake data expressed as nmol day or nmol week ; were skewed, and all analyses were performed on logtransformed data. For isoflavone excretion data, the natural log ln ; was taken. For isoflavone intake data, ln 1 was computed due to a large number of zero values within the data set. In addition to performing analyses using individual isoflavones, we also used total isoflavone excretion for each woman as the sum of the excretions of the four individual isoflavones. We compared urinary excretion of isoflavones according to soy consumer status using parametric t tests. Pearson correlations were calculated to estimate the association between isoflavone excretion in the two urine samples collected 48 h apart and between isoflavone excretion and soy isoflavone intake. Geometric means and 95% CIs were calculated from the log-transformed data. Results Participants in this study averaged 43.3 years of age range, 25.0 59.0 years; Table 1 ; at recruitment into the main casecontrol study. Data on ethnicity, household income, and level of education are presented in Table 1. Detectable levels of at least one of the four isoflavones measured were found in either overnight urine sample from 355 97.8% ; of the women. Detectable levels of genistein and daidzein were found in urine samples from 228 62.8% ; and 294 81.0% ; women, respectively, on night 1 and from 224 61.7% ; and 281 77.4% ; women, respectively, on night 2. Pearson correlations between the two measures of urinary isoflavone excretion samples collected 48 h apart ; were as follows: a ; genistein, r 0.41 and P 0.001; b ; daidzein, r 0.30 and P 0.001; c ; ODMA, r 0.46 and P 0.001; and d ; equol, r 0.60 and P 0.001. Paired t tests on log-transformed data showed no significant difference in total isoflavone excretion between the two nights when considering all women 0.76 and 0.77 nmol mg Cr on nights 1 and 2, respectively; P 0.82 ; , soy consumers on either day of the diet recall 2.71 and 2.28 nmol mg Cr on nights 1 and 2, respectively; P 0.39 ; , soy nonconsumers on both days of the diet recall 0.54 and 0.58 nmol mg Cr on nights 1 and 2, respec. IMMUNE RESPONSE OF BETA THALASSEMIC PATIENTS TO HEPATITIS B VACCINE AND TITRATION OF ANTIBODY Dr. Azita Azarkeivan M.D Member board of Iranian Blood Transfusion Organization ; Hepatitis B vaccine is obligatory for beta thalassemia patients, but the immune response to vaccination is less than healthy individuals. We studied the immune status of our patients for Hepatitis B Virus HBV ; in Adult Thalassemia Clinic in Tehran, which covers Thalassemia Major TM ; , Intermedia TI ; , Sickle Thalassemia ST ; and Hb H disease patients. METHOD We checked Hepatitis B surface antigen HBsAg ; Hepatitis B surface antibody HBsAb ; , Hepatitis B core antibody HBcAb ; .We classified the Immune status of patients to four category; 1 Immune to HBV via the vaccination positive vaccinal ; If HBs Ag: negative, HBsAb: positive, HBc Ab: negative; 2 Immune to HBV via the natural disease past infection ; If HBs: negative, HBsAb: positive, HBcAb: positive; 3 Non immune to HBV negative ; If all three parameters were negative; 4 Carrier of HBV carrier state ; If HBs Ag was positive and HBs Ab and HBc Ab: both negative. We had grading of immunity to the HBV vaccine by antibody HBs Ab ; titration as below: Positive; if antibody level was more than 100 IU mL; Negative if antibody level was less than 10 IU mL and weakly positive if antibody level was 10-100 IU mL. RESULTS We studied 416 patients who were 303 72.6 % ; TM, 104 25.2 % ; TI, 7 1.4 % ; ST, and 3 0.72 % ; Hb H disease. We had 247 58.2 % ; male and 169 40 % ; female mean age was 25.6 years.256 patients 62.2% ; were splenectomized 169 TM, 83 TI, 3 ST, 1 Hb H ; . According to our classification 300 70.3% ; were positive vaccinal; 66 15.5 % ; were immune to HBV from past infection; 40 9.4 % ; were negative and 3 0.7 % ; were carrier state of HBV None of them had not active disease HBe Ag: negative ; . In grading of immunity to HBV vaccination, we had 236 76.4% ; HBsAb level more than 100 IU mL positive ; 62 20.1 % ; between 10-100 IU mL weakly positive ; and 11 3.6 % ; less than 10 IU mL negative ; . There wasn't correlation between the level of HBs Ab and spelenetomy or type of thalassemia. DISCUSSION Response rate with vaccination is more than 95% after complete course three doses ; in healthy individuals but failure to vaccination coverage seems a problem in chronically transfused patients. In European study 22% of multitransfused thalassemic patients had not response to HBV vaccination, and in Cypriot study only 45% of their patients was immunized by vaccination.There isn't any recommendation of booster dose for healthy individuals but for thalassemic patients TIF advise to check the antibody level and administration of booster dose for patients with levels less than 10 IU mL. Similar decision must be done for weakly positive HbsAb level 10-100 ; patients or serial follow up needs for possibility of the booster dose, must be considered for this group of patients. Choice. In both cases, soy-based products or the soybean itself may appear in different forms: as a natural food, as industrial products or as homemade meals. Beans are consumed as fresh produce, always hydrated and cooked before meal preparation, to inactivate antinutrient factors , and also to increase digestibility. Industrial products offer different options like beverages, isolated proteins, soy flour , precooked beans and oriental products like Tofu and Miso. Protein isoflavone and fiber contents vary in these different products, being the most popular soybean patties and soy based beverages. Even when the argentine typical diet does not traditionally include legumes, the possibilities for the incorporation of soybean in home meals are very diverse.

Isoflavones are like other estrogens in that they are two-edged swords, conferring both benefits and risk sheehan and medlock, 1995; sheehan, 1997. Isoflavone sourcesIsoflavone content in soybean mealThese changes in breast and prostate cancer risk have been mostly attributed to change to a lowsoya Western diet. In countries such as Japan, Korea, China and Taiwan, the mean daily intake of soya products has been estimated to be in the range of 1050 g compared with only 13 g in the U.S.A. [9]. The phytoestrogen family includes the lignans and members of the flavonoid family, such as the isoflavonoids ; also some of the flavones, flavanones, chalcones, coumestans and stilbenes [10]. Isoflavonoids include the isoflavones genistein and daidzein, which occur mainly as the glycosides genistin and daidzin respectively, in soya beans and, consequently, in a wide range of soya-derived foods and, to a lesser extent, in other legumes [11]. Some alcoholic beverages such as beer contain significant amounts of isoflavonoids [12]. Daidzin and genistin are hydrolysed in the large intestine by the action of bacteria ; to release genistein and daidzein. Daidzein can be metabolized in the large intestine by bacteria to form the isoflavan equol oestrogenic ; or O-desmethylangolensin non-oestrogenic ; , whereas genistein is metabolized to the non-oestrogenic p-ethyl phenol. Inter-individual variation in ability to metabolize daidzein to equol could thus influence the potential health protective effects of soya isoflavones. Plasma isoflavonoid levels in Japanese and Finnish men have been measured, and the means of the total daidzein, genistein, O-desmethylangolensin and equol levels of these men were approximately 17-fold, 44-fold, 33-fold and 55-fold higher for the Japanese subjects compared with the Finnish ones [13]. In post-menopausal Australian women following consumption of soya flour, mean plasma levels of daidzein and equol of 68 ng\ml and 31 ng\ml respectively were observed [14]. Interestingly, only 33 % of subjects were able to metabolize daidzein to equol [14]. The bioavailabilities of genistein and daidzein are similar despite differences in urinary excretion, as shown by the approximately equal areas under their plasma concentrationtime curves ; [15]. A variable metabolic response to isoflavones has been shown for subjects following consumption of soya flour ; urinary excretion concentrations of genistein, daidzein, equol and O-desmethylangolensin were increased 8-fold, 4-fold, 45-fold and 66-fold respectively, compared with baseline levels [16]. Great interindividual variation in metabolic response was reported, with the peak levels of equol showing the most variation [16]. In.
