Projecto n. 48, Sessão de 4 de agosto de 1884 : parecer n. 48A, formulado em nome das Commissões Reunidas de Orçamento e Justiça Civil, acerca do projecto de emancipação dos escravos

Rui de Oliveira Barbosa, jurisconsulto e estadista, nasceu em Salvador, em 1849, e morreu em Petrópolis, Rio de Janeiro, em 1923. Iniciou o curso de Direito na Faculdade do Recife, em 1866, concluindo-se na Faculdade de Direito de São Paulo, em 1870. Entusiasta da campanha abolicionista, escreveu artigos, ainda como estudante, no jornal o Radical Paulistano e no Diário da Bahia. Elegeu-se deputado-geral pela Bahia, em 1878. Destacando-se nas discussões sobre as eleições diretas, abolição da escravatura e reforma do ensino. Com a Proclamação da República, foi nomeado Ministro da Fazenda do Governo Provisório e Vice-Presidente da República, quando defendeu a primeira Constituição da República na imprensa e no Parlamento. Em 1891, foi eleito Senador pela Bahia, mandato que desempenhou até sua morte, em 1923. Rui Barbosa foi autor dos decretos da proclamação da Bandeira Nacional, da liberdade de cultos e de tantos outros que estruturaram as instituições democráticas brasileiras. Em 1907, chefiou a delegação do Brasil à II Conferência da Paz, em Haia, onde defendeu o princípio da igualdade entre as nações. Sócio fundador da Academia Brasileira de Letras, foi eleito seu presidente, cargo que ocupou até 1919. Rui Barbosa não foi apenas notável como jurisconsulto, mas também como orador, conferencista, jornalista e escritor. Sendo considerado, hoje, um dos grandes clássicos da língua portuguesa. Projecto n. 48... de julho de 1884, traz, na íntegra, o projeto de lei, do qual Rui Barbosa foi relator, que objetivava abolir a escravatura no Brasil, mas que foi rejeitado pela Câmara dos Deputados. De acordo com Sacramento Blake, esse projeto foi publicado no Diário Oficial e depois em outra fontes da Corte.

Function of microRNA-146a and NF-κB in physiologic and pathologic hematopoiesis

During inflammation and infection, hematopoietic stem and progenitor cells (HSPCs) are stimulated to proliferate and differentiate into mature immune cells, especially of the myeloid lineage. MicroRNA-146a (miR-146a) is a critical negative regulator of inflammation. Deletion of the gene encoding miR-146a—expressed in all blood cell types—produces effects that appear as dysregulated inflammatory hematopoiesis, leading to a decline in the number and quality of hematopoietic stem cells (HSCs), excessive myeloproliferation, and, ultimately, to exhaustion of the HSCs and hematopoietic neoplasms. Six-week-old deleted mice are normal, with no effect on cell numbers, but by 4 months bone marrow hypercellularity can be seen, and by 8 months marrow exhaustion is becoming evident. The ability of HSCs to replenish the entire hematopoietic repertoire in a myelo-ablated mouse also declines precipitously as miR-146a-deficient mice age. In the absence of miR-146a, LPS-mediated serial inflammatory stimulation accelerates the effects of aging. This chronic inflammatory stress on HSCs in deleted mice involves a molecular axis consisting of upregulation of the signaling protein TRAF6 leading to excessive activity of the transcription factor NF-κB and overproduction of the cytokine IL-6. At the cellular level, transplant studies show that the defects are attributable to both an intrinsic problem in the miR-146a-deficient HSCs and extrinsic effects of miR-146a-deficient lymphocytes and non-hematopoietic cells. This study has identified a microRNA, miR-146a, to be a critical regulator of HSC homeostasis during chronic inflammatory challenge in mice and has provided a molecular connection between chronic inflammation and the development of bone marrow failure and myeloproliferative neoplasms. This may have implications for human hematopoietic malignancies, such as myelodysplastic syndrome, which frequently displays downregulated miR-146a expression.

Measurement of the direct CP asymmetry in b-->s+gamma via sum of exclusive B Meson decays using the BABAR detector

We perform a measurement of direct CP violation in b to s+gamma Acp, and the measurement of a difference between Acp for neutral B and charged B mesons, Delta A_{X_s\gamma}, using 429 inverse femtobarn of data recorded at the Upsilon(4S) resonance with the BABAR detector. B mesons are reconstructed from 16 exclusive final states. Particle identification is done using an algorithm based on Error Correcting Output Code with an exhaustive matrix. Background rejection and best candidate selection are done using two decision tree-based classifiers. We found $\acp = 1.73%+-1.93%+-1.02% and Delta A_X_sgamma = 4.97%+-3.90%+-1.45% where the uncertainties are statistical and systematic respectively. Based on the measured value of Delta A_X_sgamma, we determine a 90% confidence interval for Im C_8g/C_7gamma, where C_7gamma and C_8g are Wilson coefficients for New Physics amplitudes, at -1.64 < Im C_8g/C_7gamma < 6.52.

Sequence specific complexation of b DNA at sites containing g,c base pairs

A series of eight related analogs of distamycin A has been synthesized. Footprinting and affinity cleaving reveal that only two of the analogs, pyridine-2- car box amide-netropsin (2-Py N) and 1-methylimidazole-2-carboxamide-netrops in (2-ImN), bind to DNA with a specificity different from that of the parent compound. A new class of sites, represented by a TGACT sequence, is a strong site for 2-PyN binding, and the major recognition site for 2-ImN on DNA. Both compounds recognize the G•C bp specifically, although A's and T's in the site may be interchanged without penalty. Additional A•T bp outside the binding site increase the binding affinity. The compounds bind in the minor groove of the DNA sequence, but protect both grooves from dimethylsulfate. The binding evidence suggests that 2-PyN or 2-ImN binding induces a DNA conformational change.

In order to understand this sequence specific complexation better, the Ackers quantitative footprinting method for measuring individual site affinity constants has been extended to small molecules. MPE•Fe(II) cleavage reactions over a 10^5 range of free ligand concentrations are analyzed by gel electrophoresis. The decrease in cleavage is calculated by densitometry of a gel autoradiogram. The apparent fraction of DNA bound is then calculated from the amount of cleavage protection. The data is fitted to a theoretical curve using non-linear least squares techniques. Affinity constants at four individual sites are determined simultaneously. The distamycin A analog binds solely at A•T rich sites. Affinities range from 10^(6)- 10^(7)M^(-1) The data for parent compound D fit closely to a monomeric binding curve. 2-PyN binds both A•T sites and the TGTCA site with an apparent affinity constant of 10^(5) M^(-1). 2-ImN binds A•T sites with affinities less than 5 x 10^(4) M^(-1). The affinity of 2-ImN for the TGTCA site does not change significantly from the 2-PyN value. At the TGTCA site, the experimental data fit a dimeric binding curve better than a monomeric curve. Both 2-PyN and 2-ImN have substantially lower DNA affinities than closely related compounds.

In order to probe the requirements of this new binding site, fourteen other derivatives have been synthesized and tested. All compounds that recognize the TGTCA site have a heterocyclic aromatic nitrogen ortho to the N or C-terminal amide of the netropsin subunit. Specificity is strongly affected by the overall length of the small molecule. Only compounds that consist of at least three aromatic rings linked by amides exhibit TGTCA site binding. Specificity is only weakly altered by substitution on the pyridine ring, which correlates best with steric factors. A model is proposed for TGTCA site binding that has as its key feature hydrogen bonding to both G's by the small molecule. The specificity is determined by the sequence dependence of the distance between G's.

One derivative of 2-PyN exhibits pH dependent sequence specificity. At low pH, 4-dimethylaminopyridine-2-carboxamide-netropsin binds tightly to A•T sites. At high pH, 4-Me_(2)NPyN binds most tightly to the TGTCA site. In aqueous solution, this compound protonates at the pyridine nitrogen at pH 6. Thus presence of the protonated form correlates with A•T specificity.

The binding site of a class of eukaryotic transcriptional activators typified by yeast protein GCN4 and the mammalian oncogene Jun contains a strong 2-ImN binding site. Specificity requirements for the protein and small molecule are similar. GCN4 and 2-lmN bind simultaneously to the same binding site. GCN4 alters the cleavage pattern of 2-ImN-EDTA derivative at only one of its binding sites. The details of the interaction suggest that GCN4 alters the conformation of an AAAAAAA sequence adjacent to its binding site. The presence of a yeast counterpart to Jun partially blocks 2-lmN binding. The differences do not appear to be caused by direct interactions between 2-lmN and the proteins, but by induced conformational changes in the DNA protein complex. It is likely that the observed differences in complexation are involved in the varying sequence specificity of these proteins.

Experimente über die Wirkung von UV-B auf pelagische Fischembryonen in einem Sonnenscheinsimulator

One of the supposed effects of the observed ozone depletion is the increase of solar UV-B irradiation at the seasurface. This will cause an impact on certain compartments of marine ecosystems. Especially, sensitive developmental stages of pelagic fish embryos might be affected. Embryos of dab (Limanda limanda) and plaice (Pleuronectes plalessa) were experimentally exposed 10 different amounts of UVB irradiation in a sunshine simulator. This programmable device allows the dosage of realistic solar irradiation in quality and guantity. Experiments were carried out in March 1995 and February 1996. Either artificially inserninated and reared emhryos of dab and plaice or embryos caught in the German Bight were exposed to simulated solar irradiation. The 1995 experiments served to identify the effective irradiation dosages. For the 1996 experiments irradiation applied was much lower, being dose to realistic valucs expected over the North Sea as a consequence of ozone depletion. The following end points were studied: 1. Mortality, 2. sublethal morphological effects (malformations), 3. DNA damage, 4. changes in buoyancy of embryos measured as changes in osmolarity of the perivitelline fluid. Conditions for the simulation of daylight were a c1oudless sky with a solar zenith distance of 34 % (air mass 1.2). The adopted ozone depletion was 40 % corresponding to 180 DU (Dobson Units) instead of 300 DU. In the 1995 experiments time and dosage dependent influenccs on mortality and buoyancy of embryos of dab and plaice were found. Even in those embryos which were protected from the UV-B spectral range a loss of buoyancy was registered after 12 hours in the simulator. No diffcrences in DNA integrity as determined by DNA unwinding of exposed and control embryos were found. Also with lower amounts of irradiation in the 1996 experiments dosage dependent acute mortality, malformations, and impact on the buoyancy of the emhryos was registered. Sublethal effects occurred as well in embryos protected against UV-B in the exposure chambers, but were not found in the dark controls. The impact of low dosages of UV-B on the buoyancy of pelagic fish embryos might indicate an important ecological threat and deserves further studies.

Short-pulse laser absorption via J x B heating in ultrahigh intensity laser plasma interaction

An analytical fluid model for JxB heating during the normal incidence by a short ultraintense linearly polarized laser on a solid-density plasma is proposed. The steepening of an originally smooth electron density profile as the electrons are pushed inward by the laser is included self-consistently. It is shown that the JxB heating includes two distinct coupling processes depending on the initial laser and plasma conditions: for a moderate intensity (a <= 1), the ponderomotive force of the laser light can drive a large plasma wave at the point n(e)=4 gamma(0)n(c) resonantly. When this plasma wave is damped, the energy is transferred to the plasma. At higher intensity, the electron density is steepened to a high level by the time-independent ponderomotive force, n(e)> 4 gamma(0)n(c), so that no 2 omega resonance will occur, but the longitudinal component of the oscillating ponderomotive field can lead to an absorption mechanism similar to "vacuum heating."

Studies toward the total synthesis of ritterazine B : the investigation of alkynylation reactions for use in the synthesis of the western fragment

The ritterazine and cephalostatin natural products have biological activities and structures that are interesting to synthetic organic chemists. These products have been found to exhibit significant cytotoxicity against P388 murine leukemia cells, and therefore have the potential to be used as anticancer drugs. The ritterazines and cephalostatins are steroidal dimers joined by a central pyrazine ring. Given that the steroid halves are unsymmetrical and highly oxygenated, there are several challenges in synthesizing these compounds in an organic laboratory.

Ritterazine B is the most potent derivative in the ritterazine family. Its biological activity is comparable to drugs that are being used to treat cancer today. For this reason, and the fact that there are no reported syntheses of ritterazine B to date, our lab set out to synthesize this natural product.

Herein, efforts toward the synthesis of the western fragment of ritterazine B are described. Two different routes are explored to access a common intermediate. An alkyne conjugate addition reaction was initially investigated due to the success of this key reaction in the synthesis of the eastern fragment. However, it has been found that a propargylation reaction has greater reactivity and yields, and has the potential to reduce the step count of the synthesis of the western fragment of ritterazine B.

A study of T = 2 states in ^(12)B, ^(12)C, ^(20)F and ^(28)Al

The lowest T = 2 states have been identified and studied in the nuclei ¹²C, ¹²B, ²⁰F and and ²⁸Al. The first two of these were produced in the reactions ¹⁴C(p,t)¹²C and ¹⁴C (p,³He)¹²B, at 50.5 and 63.4 MeV incident proton energy respectively, at the Oak Ridge National Laboratory. The T = 2 states in ²⁰F and ²⁸Al were observed in (³He,p) reactions at 12-MeV incident energy, with the Caltech Tandem accelerator.

The results for the four nuclei studied are summarized below:

(1) ¹²C: the lowest T = 2 state was located at an excitation energy of 27595 ± 20 keV, and has a width less than 35 keV.

(2) ¹²B: the lowest T = 2 state was found at an excitation energy of 12710 ± 20 keV. The width was determined to be less than 54 keV and the spin and parity were confirmed to be 0⁺. A second ¹²B state (or doublet) was observed at an excitation energy of 14860 ± 30 keV with a width (if the group corresponds to a single state) of 226 ± 30 keV.

(3) ²⁰F: the lowest T = 2 state was observed at an excitation of 6513 ± 5 keV; the spin and parity were confirmed to be 0⁺. A second state, tentatively identified as T = 2 from the level spacing, was located at 8210 ± 6 keV.

(4) ²⁸Al: the lowest T = 2 state was identified at an excitation of 5997 ± 6 keV; the spin and parity were confirmed to be 0⁺. A second state at an excitation energy of 7491 ± 11 keV is tentatively identified as T = 2, with a corresponding (tentative) spin and parity assignment J^π = 2⁺.

The results of the present work and the other known masses of T = 2 states and nuclei for 8 ≤ A ≤ 28 are summarized, and massequation coefficients have been extracted for these multiplets. These coefficients were compared with those from T = 1 multiplets, and then used to predict the mass and stability of each of the unobserved members of the T = 2 multiplets.

Desenvolvimento de técnica de análise de imagens digitais para avaliação do estágio da fibrose em biópsias hepáticas de pacientes portadores de hepatite crônica por vírus da hepatite B e C

As hepatites crônicas por vírus são as mais frequentes, destacando-se os vírus das hepatites B (VHB) e C (VHC). O estudo anatomopatológico da biópsia hepática é considerado o padrão ouro para avaliar com precisão a distorção arquitetural e o grau de fibrose do parênquima do fígado, importantes fatores prognósticos para os pacientes portadores de hepatites crônicas virais. Na avaliação histopatológica atual, em adição aos relatos subjetivos das alterações histológicas, escores semiquantitativos que correlacionam achados morfológicos com graus numéricos são usados, tais como os reconhecidos escores de Ishak e METAVIR. Entretanto, em todos estes sistemas há a desvantagem da subjetividade do examinador e da incorporação de alterações categóricas, sem referências às mudanças quantitativas do colágeno hepático. Técnicas de análise de imagens digitais (AID) que fornecem quantificação objetiva dos graus de fibrose em amostras histológicas têm sido desenvolvidas. Todavia, o alto custo e dificuldade ao acesso das tecnologias descritas restringem seu uso a poucos centros especializados. Este estudo visa o desenvolvimento de uma técnica de custo acessível para a análise de imagens digitais da fibrose hepática em hepatites crônicas virais. Foram estudadas 304 biópsias de pacientes com hepatite crônica por vírus B e C, obtidas através de agulhas Menghini. Todas as amostras tinham pelo menos 15 mm de comprimento ou cinco espaços-porta completos e foram coradas pelo método Tricrômico de Masson. O estadiamento foi feito por um único hepatopatologista experiente, sem o conhecimento dos dados clínicos dos pacientes. Os escores de Ishak e METAVIR foram aplicados. As imagens microscópicas foram digitalizadas. Os índices de fibrose foram determinados de forma automatizada, em técnica desenvolvida no programa Adobe Photoshop. Para o escore de Ishak, observamos os seguintes índices de Fibrose (IF) médios: 0,8% 0,0 (estágio 0), 2.4% 0,6 (estágio 1), 4,7% 1,6 (estágio 2), 7,4% 1,4 (estágio 3), 14,9% 3,7 (estágio 4), 23,4% 2,9 (estágio 5) e 34,5% 1,5 (estágio 6). Para a classificação METAVIR: 0,8% 0,1 (estágio F0), 3,8% 1,8 (estágio F1), 7,4% 1,4 (estágio F2), 20,4% 5,2 (estágio F3) e 34,5% 1,5 (estágio F4). Observamos uma excelente correlação entre os índices de fibrose da AID e os escores de Ishak (r=0,94; p<0,001) e METAVIR (r=0,92; p<0,001). Em relação à indicação de tratamento antiviral, foi observado IF médio de 16,4%. Em relação ao diagnóstico de cirrose, foi observado IF médio de 26,9%, para o escore de Ishak, e 34,5% para a classificação METAVIR. A reprodutibilidade intra-observador foi excelente. Este novo método de análise de imagens digitais para a quantificação de fibrose hepática tem custo acessível e foi desenvolvido com tecnologia que está disponível em todo o mundo, permitindo identificar com precisão todos os estágios de fibrose, com excelente reprodutibilidade intra-observador.
