Determinação e comparação dos valôres Mi, A, Y e S, em dois tipos de solo do est. de S. Paulo

No presente trabalho, determinou-se e comparou-se os valores Mi de BARBIER et al., 1954, SCHEFFER e ULRICH, 1958, A de FRIED e DEAN, 1952 Y de LARSEN, 1952, e S de SOKOLOV, 1958, em dois tipos de solo do Estado de São Paulo: terra roxa legítima e um solo arenoso do campo da Secção Técnica de Química Agrícola da Escola Superior de Agricultura "Luiz de Queiroz". Aplicou-se 23,58 mg de fósforo, por vaso, na forma de superfosfato simples, contendo fósforo radioativo com uma atividade de 120.736 ipm; na forma de solução, aplicou-se também 200 mg de NH4N0(3) e 100 mg de KC1. Misturou-se bem para que houvesse homogenização a mais perfeita possível. Depois plantou-se 25 sementes de trigo, variedade 1146BH, deixando-se apenas 16 plantas após o desbaste. Procedeu-se àcolheita 55 dias após o plantio. Tanto a parte aérea como as raízes foram sêcas em estufa a 70-80°C. Sôbre o material triturado, digerido e diluído, retirou-se partes alíquotas para a determinação do P81 e do P32. Os valores obtidos para os dois tipos de solos foram os seguintes: mg de P por 1,5 kg de solo Valores Terra roxa legítima Solo arenoso Mi 177,96 92,62 A 177,55 92,71 Y 178,97 92,98 S 173,42 64,75 A análise estatística não revelou diferença significativa entre os valores Mi, A e Y, mas sim dêstes para o valor S. Quanto a este último valor, pode-se dizer que quanto mais rico em fósforo fôr o solo e quanto menor fôr o teor dêste elemento na semente, quanto mais êle deverá se aproximar dos valores Mi, A e Y.

Estudos sobre a correção da acidez do solo causada pelo Al+3 trocável. I. Efeitos sobre o pH, Al+3 e H+ trocáveis em solos das séries Sertãozinho e Monte Olimpo e das unidades 2 e 18

Ê descrito um ensaio de incubação com a finalidade de estudar os efeitos da adição de CaCO3 sobre o pH e Al³+ e H+ trocáveis de 4 terras, servindo-se do método do Al³+ trocàvel para a determinação das doses de CaCO3. De um modo geral, se encontrou uma forte elevação nos índices pH das terras e redução nos teores de Al³+ e de H+ trocáveis das mesmas, à medida em que se aumentavam as quantidades de CaCO3 empregadas. A dose 1 de CaCO3, que correspondia à quantidade de cálcio estequiometricamente igual à de Al³+ trocável presente em cada terra, foi suficiente para elevar o pH de todas elas ao redor de 5,7. O teor de Al³+ trocável, contudo, em uma delas permaneceu acima do nível considerado não tóxico às plantas.

Análisis jurisprudencial del derecho al secreto de las comunicaciones (art. 18.3 C.E.)

Este trabajo aspira a plantear en qué estado se halla actualmente la regulación de la intervención de las comunicaciones telefónicas en nuestro ordenamiento jurídico. Nuestro enfoque en el presente trabajo será plantearnos la legitimidad o licitud de las medidas de intervención telefónica así como su ámbito de validez y eficacia a efectos de su utilización en el proceso penal en el sentido de qué límites o controles deben establecerse. Asimismo analizaremos el derecho fundamental al secreto de las comunicaciones consagrado en el art. 18.3 de la Constitución y la regulación positiva de dicho derecho en nuestro ordenamiento jurídico. En definitiva, se trata de plantear la problemática en términos amplios para posteriormente profundizar y abordar cuestiones de gran relevancia tales como qué sucede o qué tratamiento debe darse a los llamados hallazgos casuales o a la prueba ilegalmente obtenida, elementos que debido a su extensión trataremos de una forma puntual y que serán objeto de desarrollo en un trabajo posterior.

Can a targeted psychological intervention be effective for young people following a first manic episode? Results from an 18-month pilot study.

Aim: There is a scarce literature describing psychological interventions for a young, first-episode cohort who have experienced psychotic mania. This study aimed to assess whether a manualized psychological intervention could be effective in reducing symptomatology and relapse, and improve functional outcome in this population. Methods: The study was an open-label design, drawn from a larger pharmacotherapy trial. All participants in the pharmacotherapy trial were offered a manualized psychological intervention in addition to case management. Inclusion in the psychotherapy group was based on participant's choice, and on completion of four or more of the eight modules offered. All clinical files were audited to ensure accuracy of group allocation. Forty young people aged 15 to 25 years old who had experienced a manic episode with psychotic features were recruited into the study, with 20 people in the combined treatment as usual plus psychotherapy group (P+TAU), and an equal number of matched control participants who received treatment as usual (TAU) within the same service. All participants were prescribed antipsychotic and mood-stabilizing medication. Symptomatic, functional and relapse measures were taken both at baseline and at 18-month follow-up. Results: Manic symptoms improved significantly for both groups, with no differences between groups. Depression scores and overall symptom severity were significantly lower in the P + TAU group. No differences were evident between groups with regard to numbers or type of relapse. The P + TAU group had significantly better social and occupational functioning after 18 months. Conclusion: This study suggests that a manualized psychological intervention targeted to a first-episode population can be effective in reducing depression and overall symptom severity, and can improve functional outcome following a first episode of psychotic mania.

Contribution of TIR domain-containing adapter inducing IFN-beta-mediated IL-18 release to LPS-induced liver injury in mice.

BACKGROUND/AIMS: After treatment with heat-killed Propionibacterium acnes mice show dense hepatic granuloma formation. Such mice develop liver injury in an interleukin (IL)-18-dependent manner after challenge with a sublethal dose LPS. As previously shown, LPS-stimulated Kupffer cells secrete IL-18 depending on caspase-1 and Toll-like receptor (TLR)-4 but independently of its signal adaptor myeloid differentiation factor 88 (MyD88), suggesting importance of another signal adaptor TIR domain-containing adapter inducing IFN-beta (TRIF). Nalp3 inflammasome reportedly controls caspase-1 activation. Here we investigated the roles of MyD88 and TRIF in P. acnes-induced hepatic granuloma formation and LPS-induced caspase-1 activation for IL-18 release. METHODS: Mice were sequentially treated with P. acnes and LPS, and their serum IL-18 levels and liver injuries were determined by ELISA and ALT/AST measurement, respectively. Active caspase-1 in LPS-stimulated Kupffer cells was determined by Western blotting. RESULTS: Macrophage-ablated mice lacked P. acnes-induced hepatic granuloma formation and LPS-induced serum IL-18 elevation and liver injury. Myd88(-/-) Kupffer cells, but not Trif(-/-) cells, exhibited normal caspase-1 activation upon TLR4 engagement in vitro. Myd88(-/-) mice failed to develop hepatic granulomas after P. acnes treatment and liver injury induced by LPS challenge. In contrast, Trif(-/-) mice normally formed the hepatic granulomas, but could not release IL-18 or develop the liver injury. Nalp3(-/-) mice showed the same phenotypes of Trif(-/-) mice. CONCLUSIONS: Propionibacterium acnes treatment MyD88-dependently induced hepatic granuloma formation. Subsequent LPS TRIF-dependently activated caspase-1 via Nalp3 inflammasome and induced IL-18 release, eventually leading to the liver injury.
