Improving the field production environment for soybeans

During the past 10 years, soybeans have reached a prominent position among crops in the world. A substantial contribution to world production has been achieved by tropical countries, due to favorable conditions for high yields. Two limitations keep commercial yields below those obtained in experimental results (above 3,000 kg/ha): one is the lack of local adapted varieties and the other is an adequate field production environment. Solutions must be obtained by local research data. Seedbed preparation is one of the most important production steps, since the other production practices are dependent on it. Conventional methods and minimum tillage, when soybeans follow another crop, are being used, with the problem of soil compaction and losses by erosion. Looking for superior strains of Rhizobium is crucial because nitrogen can be supplied by a proper symbiosis. The addition of limestone to the soil is a common practice used to raise the pH to proper levels. The use of fertilizers should be guided by local research findings. Chemical control of weeds, pests and diseases is needed to prevent yield losses, but possible effects on the environment should be considered. © 1981 American Oil Chemists' Society.

Chronic Conventional resistance exercise reduces blood pressure in stage 1 Hypertensive men

Moraes, MR, Bacurau, RFP, Casarini, DE, Jara, ZP, Ronchi, FA, Almeida, SS, Higa, EMS, Pudo, MA, Rosa, TS, Haro, AS, Barros, CC, Pesquero, JB, Wurtele, M, and Araujo, RC. Chronic conventional resistance exercise reduces blood pressure in stage 1 hypertensive men. J Strength Cond Res 26(4): 1122-1129, 2012-To investigate the antihypertensive effects of conventional resistance exercise (RE) on the blood pressure (BP) of hypertensive subjects, 15 middle-aged (46 +/- 3 years) hypertensive volunteers, deprived of antihypertensive medication (reaching 153 +/- 6/93 +/- 2 mmHg systolic/diastolic BP after a 6-week medication washout period) were submitted to a 12-week conventional RE training program (3 sets of 12 repetitions at 60% 1 repetition maximum, 3 times a week on nonconsecutive days). Blood pressure was measured in all phases of the study (washout, training, detraining). Additionally, the plasma levels of several vasodilators or vasoconstrictors that potentially could be involved with the effects of RE on BP were evaluated pre- and posttraining. Conventional RE significantly reduced systolic, diastolic, and mean BP, respectively, by an average of 16 (p < 0.001), 12 (p < 0.01), and 13 mm Hg (p < 0.01) to prehypertensive values. There were no significant changes of vasoactive factors from the kallikrein-kinin or renin-angiotensin systems. After the RE training program, the BP values remained stable during a 4-week detraining period. Taken together, this study shows for the first time that conventional moderate-intensity RE alone is able to reduce the BP of stage 1 hypertensive subjects free of antihypertensive medication. Moreover, the benefits of BP reduction achieved with RE training remained unchanged for up to 4 weeks without exercise.

Proposta de estrutura para o gerenciamento de projetos de revitalização urbana

Os projetos de revitalização urbana são realizações do poder público a partir da identificação de áreas degradadas ou que necessitam de projetos especiais. Para a sua execução, o governo precisa desenvolver uma estrutura gerencial especialmente organizada para este fim. Atualmente ainda não existe uma estrutura de gerenciamento sólida o suficiente para ser utilizada como modelo e replicada em diferentes áreas ou escalas no país. Esta carência está se tornando mais visível em consequência do aumento das parcerias entre o poder público e empresas privadas, viabilizando muitos destes projetos no Brasil mas que, em contrapartida, pressionam o governo a se movimentar para estabelecer uma estrutura eficiente a fim de executá-los no mesmo ritmo que as empresas privadas impõem no desenvolvimento de empreendimentos próprios. Assim, o presente trabalho teve como objetivo reconhecer os principais elementos que compõem a estrutura de gerenciamento de um projeto público de revitalização urbana, levantando informações através da literatura, de três projetos de revitalização urbana já realizados no Brasil e no exterior, procurando extrair as boas práticas1 , e propondo por fim, uma estrutura que permita servir como direcionamento para gerenciadoras ou partes interessadas, com a possibilidade de replicação em diferentes escalas de projetos urbanos. Os resultados encontrados foram separados pelo presente autor em seis fases que, entendem-se relevantes para o planejamento macro da estrutura do ciclo de vida dos projetos de revitalização urbana, sendo estes: (i) Fase de Iniciação, (ii) Fase de Formulação, (iii) Fase de Planejamento e Estrutura, (iv) Fase de Execução, (v) Fase de Monitoramento e Controle e (vi) Fase de Encerramento. O presente artigo é parte de uma pesquisa mais abrangente e detalhada que constitui uma dissertação de mestrado em andamento no programa de Pós-Graduação de Engenharia Civil da Escola Politécnica da USP.

Detection of chest trauma with whole-body low-dose linear slit digital radiography: a multireader study

The objective of our study was to compare the performance of low-dose linear slit digital radiography (DR) with computed radiography (CR) for the detection of trauma sequelae in the chest including rib fractures, pneumothorax, and lung contusion.

Immunohistochemical localization of osteoclastogenic cell mediators in feline tooth resorption and healthy teeth

Tooth resorption is among the most common and most challenging problems in feline dentistry It is a progressive disease eventually leading to tooth loss and often root replacement. The etiology of moth resorption remains obscure and to date no effective therapeutic approach is known. The present study is aimed at assessing the reliability of radiographic imaging and addressing the possible involvement of receptor activator of NF kappa B (RANK), its ligand (RANKL), and osteoprotegerin (OPG) in the process of tooth resorption. Teeth from 8 cats were investigated by means of radiographs and paraffin sections followed by immunolabeling. Six cats were diagnosed with tooth resorption based on histopathologic and radiographic findings. Samples were classified according to a four-stage diagnostic system. Radiologic assessment of tooth resorption correlated very strongly with histopathologic findings. Tooth resorption was accompanied by a strong staining with all three antibodies used, especially with anti-RANK and anti-RANKL antibodies. The presence of OPG and RANKL at the resorption site is indicative of repair attempts by fibroblasts and stromal cells. These findings should be extended by further investigations in order to elucidate the pathophysiologic processes underlying tooth resorption that might lead to prophylactic and/or therapeutic measures.

Postmortem imaging-guided biopsy as an adjuvant to minimally invasive autopsy with CT and postmortem angiography: a feasibility study

Although postmortem CT suffices for diagnosing most forms of traumatic death, the examination of natural death is, to date, very difficult and error prone. The introduction of postmortem angiography has led to improved radiologic diagnoses of natural deaths. Nevertheless, histologic changes to tissues, an important aspect in traditional examination procedures, remain obscure even with CT and CT angiography. For this reason, we examined the accuracy of a minimally invasive procedure (i.e., CT angiography combined with biopsy) in diagnosing major findings and the cause of death in natural deaths.
