Foods high in thiamin dietThe shift from independent observations to stochastic processes destabilized the identification of probabilities with frequencies. We can observe only one Solar System: the stochastic process plays itself out only once. There are recurring events in the Solar System, and so there are, as Neyman says, various frequencies to explain. But the probabilities required to define so complex a stochastic process go far beyond those that can be estimated by frequencies, and the frequencies explained may go beyond those that approximate single probabilities. Examples of frequencies that are not explained by single probabilities go back to the law of large numbers formulated by Poisson in 1837 [42]. If events E1 , have probabilities p1 , and if the relative frequency of the En the fraction that happen ; approximates the average of the pn , then the pn explain the frequency, even though the frequency does not approximate a single probability. In the framework of stochastic processes, each pn is a probability conditional on earlier events. Poisson's result was treated in this spirit by Kolmogorov in 1929 [27]. I will discuss its game-theoretic formulation in 3.3 and 3.4. Neyman dealt with the failure of classical frequentism by falling back on the thought that phenomena have "chance mechanisms" behind them. Perhaps God does play dice with the universe. With this rhetorical shift, Neyman clung to a sense of objectivity, but he lost frequentism's strong empiricism. A chance mechanism is supposed to be an objective feature of the world, but we cannot thoroughly observe and test it. We cannot refute the mere hypothesis that a phenomenon is governed by some completely unknown stochastic process. This elusiveness contributed to the resurgence of subjectivism in the late twentieth century. In more recent years, our much increased capacity to acquire, store, and analyze data has reversed somewhat the shift from the model of independent observations to stochastic processes. We now see many large datasets in which the number of variables measured greatly exceeds the number of observations [73]. We may still be interested in predicting a particular variable Y from other variables X1 , Neyman was [40], p. 626 ; , but when k is so extremely large, it often seems neither necessary nor practical to model the evolution of the system over time. Instead, we may simply assume that changes in the system are adequately summarized by current values of the Xi . But this does not bring back the strong empiricism of frequentism. We are still positing a stochastic model so vast, with so many unspecified probabilities, that it can be neither estimated nor refuted. Instead of proclaiming a proud empiricism as our predecessors in the mid-twentieth century did, we now mumble that no models are strictly true; at best they are somehow useful! Receiving- thiamin plus basal ration were hypertropliied, it is obvious that the total fat in the livers of these birds was mark edly increased over that of the controls. Similarly the total moisture was greatly increased with thiamin therapy. On the other hand, the total protein and phospholipid values com pare favorably with the controls although they are lowered in. Thiamin for womenThe concept of isosterism as applied to thiamin has been the subject of recent discussion. Schmelkes and Joiner' and Schmelkes2 described the synthesis of a compound isosteric with thiamin and reported that it had some antineuretic activity. Baumgarten and Dornow3 synthesized the same substance and reported its antineuretic activity to be about one twenty-sixth that of thiamin. It is probable, however, that the compound described by Schmelkes and by Baumgarten and Dornow was an a-hydroxyethyl derivative instead of the assumed , B-hydroxyethyl pyridine.4 Tracy and Elderfield5 synthesized the , B-hydroxyethyl compound. Their compound is 1- 4-amino-2-methyl ; 5-pyrimidylmethyl-2-methyl-3- f-hydroxyethyl ; -pyridinium bromide hydrobromide monohydrate ; . The pyrimidine6 portion of this compound is identical with that of thiamin; the pyridine portion differs from the thiazole part of thiamin as may be noted from the following formula. Epithelial cells on promoter activities in vivo. The results of our investigations showed that differentiation of intestinal epithelial cells is associated with an up-regulation in intestinal carrier-mediated thiamin uptake. This upregulation in thiamin uptake was found to be mediated at least in part ; via transcriptional regulatory mechanisms that involve induction in the activities of both the human SLC19A2 and SLC19A3 genes. MATERIALS and METHODS specific Custom-made [3H]-thiamin activity 30 Ci mmol; radiochemical purity 98.0% ; was obtained from American Radiolabeled Chemical St. Louis, MO ; . All other chemicals, reagents, and kits were of analytical molecular biology grade and were obtained from commercial sources. Cell culture and uptake studies - The humanderived intestinal epithelial Caco-2 cells ATCC, Manassas, VA ; were plated at a density of 2 X 105 cells well onto 12-well plates. Uptake studies were performed between passage 23 and 36 ; on preconfluent 1 day after seeding ; , confluent 3 days after seeding when cells were visibly confluent ; and post-confluent 5 days after seeding 3 days after confluence ; monolayers of Caco-2 cells. Uptake was measured at 37C in Krebs-Ringer buffer in mM: 133 NaCl, 4.93 KCl, 1.23 MgSO4, 0.85 CaCl2, 5 glucose, 5 glutamine, 10 HEPES, and 10 MES, pH 7.4 ; . Labeled and unlabeled thiamin was added to the incubation medium at the onset of incubation, and uptake was examined during the initial linear period 9 ; . The reaction was terminated by the addition of 2 ml ice-cold buffer followed by immediate aspiration. Cells were then rinsed twice with ice-cold buffer, digested with 1 ml of NaOH, neutralized with HCl, and then measured for radioactive content using a scintillation counter. Protein content of cell digests was measured in parallel wells by using a Bio-Rad Dc Protein Assay kit Bio-Rad, Richmond, VA ; . Isolation of mouse villus and crypt intestinal epithelial cells and uptake studies - Mouse villus and crypt intestinal epithelial cells were isolated as described before 33 ; using a well-established fractionation procedure 34 ; . Using this procedure, we collected ten consecutive fractions. Thiamin pillsIncubated with 3 mM [1-14C]KIV alone showed rates of decarboxylation of 0. 218 nmol of CO2 per min mg of protein for normal cells and 0.070 nmol of CO2 per min mg of protein for the thiamin-responsive variant cells-a rate that is 32% of the normal rate Table 1 ; . Intact classical MSUD fibroblasts had no measurable BCKA decarboxylation under similar conditions. Addition of saturating concentrations of thiamin 4 mM ; to intact normal and thiamin-responsive fibroblasts increased activity by 44 and 64%, respectively Table 1 ; . Classical MSUD intact fibroblasts continued to show no measurable decarboxylation of KIV in the presence of thiamin. The defect in decarboxylation in thiamin-responsive and classical MSUD fibroblasts was specific for KIV because pyruvate and a-ketoglutarate were decarboxylated at normal rates in mutant cells Table 1 ; . Thiamin stimulated the decarboxylation of pyruvate 20-40% ; and a-ketoglutarate 130-200% ; . In the disrupted cell assay, strains of normal skin fibroblasts derived from different subjects showed BCKA dehydrogenase activity that ranged from a low of 1.07 to a high of 1.56 nmol of CO2 per min mg of protein Table 2 ; . Disrupted cells from patients with clinically thiamin-responsive MSUD WG-34 ; and classical MSUD DaMa ; had deficient BCKA dehydrogenase activity when assayed in the presence of 0.2 mM TPP with 3 mM [1-14C]KIV. Fibroblasts from WG-34 had higher residual activity than did fibroblasts from the classical MSUD patient DaMa. On the other hand, activities of a-ketoglutarate and dichloroacetate-activated pyruvate dehydrogenase complexes appeared to be normal in both MSUD subjects, confirming the specificity of the defect in MSUD. Effect of TPP on BCKA Dehydrogenase. Because TPP is an essential cofactor for BCKA dehydrogenase, the effects of TPP on the enzyme activity of disrupted fibroblasts derived from normal subjects and those with classical MSUD GM-612 ; , variant grade 3 MSUD ElHa ; , and the clinically thiamin-responsive MSUD WG-34 ; were investigated. Disrupted normal cells exhibited hyperbolic or Michaelis-Menten kinetics over the substrate range 0.1-5.0 mM Fig. 1A ; . TPP 0.2 mM ; increased only the Vm. of the BCKA dehydrogenase without affecting the KM, which previously had been calculated to be 0.05 mM 7 ; . Disrupted classical-MSUD fibroblasts GM-612 ; showed sigmoidal enzyme kinetics with essentially no activity in the 0-1 mM range, but activity that approached 30% ofthe normal value at 5 mM concentration of substrate Fig. 1B ; . TPP 0.2 mM ; increased the Vm but did not change the K0.5, which was previously estimated to be 7 Fibroblasts from a subject with thiamin-nonresponsive grade 3 variant MSUD ElHa ; also showed Michaelis-Menten enzyme kinetics but with an in and thiotepa. Foods high in thiamin dietRate or pyruvate was used as substrate; however, he did report a decrease in oxygen utilization. In heart mitochondria from thiamin-deficient rats, Arcos et al. 30 ; re ported a decrease in oxygen utilization but no change in phosphorus oxygen ratios when pyruvate or a-ketoglutarate was used as substrate. The metabolic fate of pyruvate in mito chondria from normal, pair-fed and thia min-deficient animals is compared in ta ble 3. Pyruvate utilization was decreased 35% by pair-feeding and 80% by thiamin deficiency when compared to the normal control. The decrease in pyruvate utiliza tion results in a marked decrease in the amount of pyruvate carboxylated. However, when pyruvate carboxylation is estimated either by 14CO2 incorporation or total prod uct formation 31 ; we observe no change in the percentage pyruvate carboxylated; in all cases carboxylation was approximate ly 40% to 50% . In thiamin-deficient mito chondria there is an increase in the amount of a-ketoglutarate found 75% ; whereas the levels of malate and citrate are de creased when compared to the pair-fed con trol. This may reflect the biochemical lesion which has been previously observed in thi and thorazine. Novontrone, which must be administered by an oncologist, are sometimes prescribed, both with mixed success. I sincerely believe that our chances of reversing or managing MS over the long haul are better with the natural approach of diet and life-style changes. You are so fortunate in the U.K. in having this publication featuring alternative therapies. We unfortunately do not have an equivalent publication in the U.S. The MS Society rules supreme here, refusing to even entertain the idea that diet and lifestyle changes have any effect on MS. As a matter of fact the NMSS "official" view of my book, From MS to Wellness, is that I give people false hope. I plead "not guilty." If we do not have hope, what do we have? I wish much success to each of you in your personal journey to wellness. Thiamin absorptionFirst seen. She became pregnant and the decreased slightly but was still in the high normal range. The TPPE became unequivocally abnormal. She received a supplement of both thiamin and folate since serum folate was low. Note that TKA increased and timolol. Sunfish was what drew two bidders to tracts north of the North Cook Inlet gas field in this sale, but primarily companies appeared to be picking up acreage around existing units or acreage on the southern Kenai Peninsula or on the west side that may be prospective for gas. Kevin Banks, acting director of the Alaska Division of Oil and Gas, said after the sale that a typical Cook Inlet sale would have been in the .5 million to million range, "so getting a sale that's twice that is pretty good for us." People bought tracts around existing units, he said, including North Cook Inlet see SALE page 23 and thiamin. This paper was submitted directly Track II ; to the PNAS office.
