Glucose metabolism by lymphocytes, macrophages, and tumor cells from Walker 256 tumor-bearing rats supplemented with fish oil for one generation

Here we investigated the effect of lifelong supplementation of the diet with coconut fat (CO, rich in saturated fatty acids) or fish oil (170, rich in n-3 polyunsaturated fatty acids) on tumor growth and lactate production from glucose in Walker 256 tumor cells, peritoneal macrophages, spleen, and gut-associated lymphocytes. Female Wistar rats were supplemented with CO or FO prior to mating and then throughout pregnancy and gestation and then the male offspring were supplemented from weaning until 90 days of age. Then they were inoculated subcutaneously with Walker 256 tumor cells. Tumor weight at 14 days in control rats (those fed standard chow) and CO supplemented was approximately 30 g. Supplementation of the diet with FO significantly reduced tumor growth by 76%. Lactate production (nmol h(-1) mg(-1) protein) from glucose by Walker 256 cells in the group fed regular chow (W) was 381.8 +/- 14.9. Supplementation with coconut fat (WCO) caused a significant reduction in lactate production by 1.6-fold and with fish oil (WFO) by 3.8-fold. Spleen lymphocytes obtained from W and WCO groups had markedly increased lactate production (553 +/- 70 and 635 +/- 150) when compared to non-tumor-bearing rats (similar to 260 +/- 30). FO supplementation reduced significantly the lactate production (297 +/- 50). Gut-associated lymphocytes obtained from W and WCO groups increased lactate production markedly (280 +/- 31 and 276 +/- 25) when compared to non-tumor-bearing rats (similar to 90 +/- 18). FO supplementation reduced significantly the lactate production (168 +/- 14). Lactate production by peritoneal macrophages was increased by tumor burden but there was no difference between the groups fed the various diets. Lifelong consumption of FO protects against tumor growth and modifies glucose metabolism in Walker tumor cells and lymphocytes but not in macrophages. Copyright (C) 2008 John Wiley & Sons, Ltd.

Walker 256 tumour growth causes marked changes of glutamine metabolism in rat small intestine

The effect of Walker 256 tumour growth on the metabolism of glucose and glutamine in the small intestine of rats was examined. Walker 256 tumour has been extensively used as an experimental model to induce cancer cachexia in rats. Walker 256 tumour growth decreased body weight and small intestine weight and length. The activities of glucose-6-phosphate dehydrogenase and phosphate-dependent glutaminase were reduced in the proximal, median and distal portions of the intestine. Glutamine oxidation was reduced in the proximal portion only. The decrease in glutaminase activity was not due to a low synthesis of the protein as indicated by Western blotting analysis. Hexokinase and citrate synthase activities were not changed by the tumour. These findings led us to postulate that tumour growth impairs glutamine metabolism of small intestine but the mechanism involved remains to be elucidated. Copyright (C) 2001 John Wiley Sons, Ltd.

Bond between John Leverett and Edward Hutchinson, Treasurer of Harvard College, 1722 June 13

One-folio sized leaf containing a handwritten copy of a bond between John Leverett and Edward Hutchinson, Treasurer of Harvard. The bond was witnessed by Benjamin Walker and John Edwards, Jr. An October 3, 1726 receipt of payment from Nathaniel Byfield on the bond, signed by Treasurer Edward Hutchinson, is located on the verso of the first leaf.

John Warren's copy of votes from a meeting of the Boston Medical Society, 1784 May 3

This document lists the eleven votes cast at a meeting of the Boston Medical Society on May 3, 1784. It was authorized as a "true coppy" by Thomas Kast, the Secretary of the Society. The following members of the Society were present at the meeting, all of them doctors: James Pecker, James Lloyd, Joseph Gardner, Samuel Danforth, Isaac Rand, Jr., Charles Jarvis, Thomas Kast, Benjamin Curtis, Thomas Welsh, Nathaniel Walker Appleton, and doctors whose last names were Adams, Townsend, Eustis, Homans, and Whitwell. The document indicates that a meeting had been held the previous evening, as well (May 2, 1784), at which the topics on which votes were taken had been discussed. The votes, eleven in total, were all related to the doctors' concerns about John Warren and his involvement with the emerging medical school (now Harvard Medical School), that school's relation to almshouses, the medical care of the poor, and other related matters. The tone and content of these votes reveals anger on the part of the members of the Boston Medical Society towards Warren. This anger appears to have stemmed from the perceived threat of Warren to their own practices, exacerbated by a vote of the Harvard Corporation on April 19, 1784. This vote authorized Warren to apply to the Overseers of the Poor for the town of Boston, requesting that students in the newly-established Harvard medical program, where Warren was Professor of Anatomy and Surgery, be allowed to visit the hospital of the almshouse with their professors for the purpose of clinical instruction. Although Warren believed that the students would learn far more from these visits, in regards to surgical experience, than they could possibly learn in Cambridge, the proposal provoked great distrust from the members of the Boston Medical Society, who accused Warren of an "attempt to direct the public medical business from its usual channels" for his own financial and professional gain.

Síndrome do X Frágil com variante de Dandy-Walker: estudo clínico das manifestações comunicativas orais e escritas

A síndrome do X Frágil é a causa mais frequente de deficiência intelectual hereditária. A variante de Dandy-Walker trata-se de uma constelação específica de achados neurorradiológicos. Este estudo relata achados da comunicação oral e escrita de um menino de 15 anos com diagnóstico clínico e molecular da síndrome do X-Frágil e achados de neuroimagem do encéfalo compatíveis com variante de Dandy-Walker. A avaliação fonoaudiológica foi realizada por meio da Observação do Comportamento Comunicativo, aplicação do ABFW - Teste de Linguagem Infantil - Fonologia, Perfil de Habilidades Fonológicas, Teste de Desempenho Escolar, Teste Illinois de Habilidades Psicolinguísticas, avaliação do sistema estomatognático e avaliação audiológica. Observou-se: alteração de linguagem oral quanto às habilidades fonológicas, semânticas, pragmáticas e morfossintáticas; déficits nas habilidades psicolinguísticas (recepção auditiva, expressão verbal, combinação de sons, memória sequencial auditiva e visual, closura auditiva, associação auditiva e visual); e alterações morfológicas e funcionais do sistema estomatognático. Na leitura verificou-se dificuldades na decodificação dos símbolos gráficos e na escrita havia omissões, aglutinações e representações múltiplas com o uso predominante de vogais e dificuldades na organização viso-espacial. Em matemática, apesar do reconhecimento numérico, não realizou operações aritméticas. Não foram observadas alterações na avaliação audiológica periférica. A constelação de sintomas comportamentais, cognitivos, linguísticos e perceptivos, previstos na síndrome do X-Frágil, somada às alterações estruturais do sistema nervoso central, pertencentes à variante de Dandy-Walker, trouxeram interferências marcantes no desenvolvimento das habilidades comunicativas, no aprendizado da leitura e escrita e na integração social do indivíduo.
