BALAÃO – O QUE OUVE AS PALAVRAS DE EL, TEM O CONHECIMENTO DE ELYON E VÊ A VISÃO DE SHADDAI: UM ESTUDO DE NÚMEROS 22-24

A presente pesquisa busca avaliar exegeticamente o texto que se encontra na Bíblia, especificamente no livro de Números capítulos 22-24 que relata sobre um personagem conhecido como Balaão. A pesquisa tem também como objeto o estudo sobre o panteão de divindades relatado no mesmo texto, assim como também o estudo dos textos descobertos em Deir Alla, na Jordânia, que apresentam um personagem designado como Balaão, possivelmente o mesmo personagem de Nm 22-24. A motivação que levou ao desenvolvimento dessa pesquisa foi o fato de se ter deparado com os conceitos dos diversos nomes divinos exibidos no texto, além da questão do profetismo fora de Israel, assim como as possibilidades hermenêuticas que se abrem para a leitura desse texto bíblico. O conceito geral sempre foi o de que Israel era a única nação onde existiam “verdadeiros” profetas e uma adoração a um único Deus, o “monoteísmo”. O que despertou interesse foi perceber, especialmente por meio da leitura dos livros bíblicos, que o profetismo não se restringiu somente a Israel. Ele antecede à formação do antigo Israel e já existia no âmbito das terras do antigo Oriente Médio, e que Israel ainda demorou muito tempo para ser monoteísta. Quem é esse Balaão, filho de Beor? Estudaremos sobre sua pessoa e sua missão. Examinaremos os textos de Deir Alla sobre Balaão e sua natureza de personagem mediador entre o divino e o humano. Esse personagem é apresentado como um grande profeta e que era famoso como intérprete de presságios divinos. Analisaremos a importante questão sobre o panteão de deuses que são apresentados na narrativa de Balaão nomeados como: El, Elyon Elohim e Shaddai, além de Yahweh. Entendemos, a princípio, que o texto possui uma conexão com a sociedade na qual foi criado e usando da metodologia exegética, faremos uma análise da narrativa em questão, buscando compreender o sentido do texto, dentro de seu cenário histórico e social. Cenário este, que nos apresentou esse profeta, não israelita, que profere bênçãos dos deuses sobre Israel e que, além disso, pronuncia maldições sobre os inimigos desse mesmo Israel. Percebemos que, parte do texto pesquisado é apresentado sob a ótica de Israel sobre as outras nações. A pesquisa defende, portanto, que o texto de Nm 22-24, além de nos apresentar um profeta fora de Israel igual aos profetas da Bíblia, defende que, o panteão de divindades também era adorado por Israel e que tais nomes são epítetos de uma mesma divindade, no caso YHWH. Defende, também, um delineamento de um projeto de domínio político e militar de Israel sobre as nações circunvizinhas.

Ubiquitin-mediated regulation of 3-hydroxy-3-methylglutaryl-CoA reductase

Regulation of the sterol-synthesizing mevalonate pathway occurs in part through feedback-regulated endoplasmic reticulum degradation of 3-hydroxy-3-methylglutaryl-CoA reductase (HMG-R). In yeast, the Hmg2p isozyme of HMG-R is regulated in this manner. We have tested the involvement of ubiquitination in the regulated degradation of Hmg2p, by using both genetic and direct biochemical approaches. Hmg2p degradation required the UBC7 gene, and Hmg2p protein was directly ubiquitinated. Hmg2p ubiquitination was dependent on UBC7 and was specific for the degraded yeast Hmg2p isozyme. Furthermore, Hmg2p ubiquitination was regulated by the mevalonate pathway in a manner consistent with regulation of Hmg2p stability. Thus, regulated ubiquitination appeared to be the mechanism by which Hmg2p stability is controlled in yeast. Finally, our data indicated that the feedback signal controlling Hmg2p ubiquitination and degradation was derived from farnesyl diphosphate, and thus implied conservation of an HMG-R degradation signal between yeast and mammals.

Sequence Determinants for Regulated Degradation of Yeast 3-Hydroxy-3-Methylglutaryl-CoA Reductase, an Integral Endoplasmic Reticulum Membrane Protein

The degradation rate of 3-hydroxy-3-methylglutaryl CoA reductase (HMG-R), a key enzyme of the mevalonate pathway, is regulated through a feedback mechanism by the mevalonate pathway. To discover the intrinsic determinants involved in the regulated degradation of the yeast HMG-R isozyme Hmg2p, we replaced small regions of the Hmg2p transmembrane domain with the corresponding regions from the other, stable yeast HMG-R isozyme Hmg1p. When the first 26 amino acids of Hmg2p were replaced with the same region from Hmg1p, Hmg2p was stabilized. The stability of this mutant was not due to mislocalization, but rather to an inability to be recognized for degradation. When amino acid residues 27–54 of Hmg2p were replaced with those from Hmg1p, the mutant was still degraded, but its degradation rate was poorly regulated. The degradation of this mutant was still dependent on the first 26 amino acid residues and on the function of the HRD genes. These mutants showed altered ubiquitination levels that were well correlated with their degradative phenotypes. Neither determinant was sufficient to impart regulated degradation to Hmg1p. These studies provide evidence that there are sequence determinants in Hmg2p necessary for degradation and optimal regulation, and that independent processes may be involved in Hmg2p degradation and its regulation.

Rhesus monkeys know when they remember

Humans are consciously aware of some memories and can make verbal reports about these memories. Other memories cannot be brought to consciousness, even though they influence behavior. This conspicuous difference in access to memories is central in taxonomies of human memory systems but has been difficult to document in animal studies, suggesting that some forms of memory may be unique to humans. Here I show that rhesus macaque monkeys can report the presence or absence of memory. Although it is probably impossible to document subjective, conscious properties of memory in nonverbal animals, this result objectively demonstrates an important functional parallel with human conscious memory. Animals able to discern the presence and absence of memory should improve accuracy if allowed to decline memory tests when they have forgotten, and should decline tests most frequently when memory is attenuated experimentally. One of two monkeys examined unequivocally met these criteria under all test conditions, whereas the second monkey met them in all but one case. Probe tests were used to rule out “cueing” by a wide variety of environmental and behavioral stimuli, leaving detection of the absence of memory per se as the most likely mechanism underlying the monkeys' abilities to selectively decline memory tests when they had forgotten.

Simultaneous assessment of loss of heterozygosity at multiple microsatellite loci using semi-automated fluorescence-based detection: subregional mapping of chromosome 4 in cervical carcinoma.

Detection of loss of heterozygosity (LOH) by comparison of normal and tumor genotypes using PCR-based microsatellite loci provides considerable advantages over traditional Southern blotting-based approaches. However, current methodologies are limited by several factors, including the numbers of loci that can be evaluated for LOH in a single experiment, the discrimination of true alleles versus "stutter bands," and the use of radionucleotides in detecting PCR products. Here we describe methods for high throughput simultaneous assessment of LOH at multiple loci in human tumors; these methods rely on the detection of amplified microsatellite loci by fluorescence-based DNA sequencing technology. Data generated by this approach are processed by several computer software programs that enable the automated linear quantitation and calculation of allelic ratios, allowing rapid ascertainment of LOH. As a test of this approach, genotypes at a series of loci on chromosome 4 were determined for 58 carcinomas of the uterine cervix. The results underscore the efficacy, sensitivity, and remarkable reproducibility of this approach to LOH detection and provide subchromosomal localization of two regions of chromosome 4 commonly altered in cervical tumors.

In vivo examination of membrane protein localization and degradation with green fluorescent protein.

To test the utility of green fluorescent protein (GFP) as an in vivo reporter protein when fused to a membrane domain, we made a fusion protein between yeast hydroxymethylglutaryl-CoA reductase and GFP. Fusion proteins displayed spatial localization and regulated degradation consistent with the native hydroxymethylglutaryl-CoA reductase proteins. Thus, GFP should be useful in the study of both membrane protein localization and protein degradation in vivo.

Poems copied by James Diman, ca. 1730-1733

Small pamphlet-sized notebook containing handwritten transcriptions of three poems copied by James Diman, likely in the early 1730s. The notebook contains "The Catholic Remedy. to ye Tune of To all you Ladies, not at land &c.," "Father Ab--y's Will. Col. Sweeper Camb: Dec. 1731," and "The Poet's Lamentation for ye Loss of his cat, w'ch he used to call his Muse" copied from the London Magazine, November 1733. The "Catholic Remedy" begins "You Peope who desire to mend / your Desperate Estate..." and includes the note, "Made upon A--D--'s goving over to take orders. The note refers to the voyage of Addington Davenport (Harvard AB 1719) to England join the priesthood of the Church of England in 1730. "Father Ab--y's Will" begins "To my dear Wife, / My joy and Life..." and was a humorous poem published in 1731 after the death of Harvard College Sweeper Matthew Abdy, and attributed to Jonathan Seccombe (Harvard AB 1728). The "Poet's Lamentation" begins "Oppress'd with Grief, in heavy strains I mourn..." and was written by Joseph Green (Harvard AB 1726) as a parody of a psalm composed by Mather Byles (Harvard AB 1725). Pages 10-12, holding part of "Father Ab--y's Will" are missing, and pages 13-15 are no longer attached to the item.
