The management of fertilization in maize plants is a preponderant factor in the search for higher yields and obtaining quality seeds. In this sense, the study of nitrogen (N) management is predominant in improving the efficiency of its application. The objective of this study was to evaluate the growth, partition assimilation and vigor expression of maize seeds submitted at different doses of nitrogen applied at sowing. The treatments were constituted by different doses of nitrogen fertilization at sowing, being: 25%, 50%, 75% and 100% of the recommended dose for the crop, according to the recommendation of nitrogen fertilization. The plants were collected at regular intervals of 21 days after sowing until the end of the growth cycle. For the analysis of growth and partition of dry matter between the organs, the accumulation of dry matter and leaf area was measured. The experimental design was randomized blocks in a 4 × 7 factorial scheme (four N rates at sowing and seven collection times with three replications). The maize plants under the influence of nitrogen fertilization at sowing presented differential growth and distinct responses in the assimilated partition between their structures, with the intensity dependent on the dose used. Plants grown using 75% of the recommended dose of N at sowing had a higher relative growth rate, with more pronounced effects compared to the other doses. The expression of maize seed vigor increases to an increase of 82.5% N at sowing.

Toll-Like Receptors as Biomarkers of Gastric Carcinogenesis:Implications for Diagnosis,Prognosis and Treatment

引用

Journal of Cancer Therapy 2013年第5期4卷 1037-1047页

作者： Pedro Pimentel-Nunes joao Bruno Soares Mário Dinis-Ribeiro Department of Physiology Cardiovascular Research&Development UnitFaculty of MedicineUniversity of PortoPortoPortugal Gastroenterology Department Portuguese Oncology InstitutePortoPortugal Gastroenterology Department Hospital de BragaBragaPortugal CIDES/CINTESIS Faculty of MedicineUniversity of PortoPortoPortugal

Toll-like receptors (TLR) are essential for Helicobacter pylori (Hp) recognition and subsequent innate and adaptive immunity responses. TLR2 appears to be the receptor responsible for most of the immunologic reaction against Hp infection. However, TLR4, TLR9 and eventually TLR5 may also have a synergic effect with TLR2 against Hp. It has been shown that gastric Hp infection increases TLR expression in the gastric mucosa. Moreover, recent studies have shown that human gastric carcinogenesis is associated not only with increased expression of TLR but also with decreased expression of their inhibitors such as Toll-Interacting Protein (TOLLIP) and peroxisome proliferator-activated receptor (PPAR)-g. Indeed, gastric dysplasia and adenocarcinoma are associated with high expression levels of TLR and low levels of TOLLIP and PPAR-g, suggesting increased activation of these receptors throughout human gastric carcinogenesis. In this article we discuss how these novels findings could be used not only for the diagnosis and prognosis of gastric lesions associated with Hp infection but also for their treatment. Specifically, we discuss the potential use of TLR agonists in addition to antibiotics to improve eradication rates of Hp and of TLR antagonists to slow the progression of gastric preneoplastic lesions. We also discuss the potential value of TLR signalling blockers and quantification of tumoral TLR expression, respectively, in the treatment and prognosis of gastric cancer. In conclusion, TLRs can be an important link between Hp and the sequence of gastric carcinogenesis and they can be used as biomarkers of gastric carcinogenesis. In this article, future lines of investigation related with these novel scientific findings are proposed and discussed.

Psidium guajava L. has extensive use in folk medicine. The aim of this study was to quantify the levels of phenolic, flavonoids, antioxidant activity, leathality assay and antibacterial and antitumoral activities of the extract of P. guajava. In the dry guava extract there were high levels of phenolics (766.08 ± 14.52 mg/g), flavonoids (118.90 ± 5.47 mg/g) and antioxidant activity (87.65%). The LD50 was 185.15 μg/ml. The MIC value was 250 μg/ml for Streptococcus mutans, Streptococcus mitis and Streptococcus oralis. IC50 of the extract tested in the HeLa, RKO and Wi cell lines was 15.6 ± 0.8 μg/ml, 21.2 ± 1.1 μg/ml and 68.9 ± 1.5 μg/ml, respectively. The results of all analyses allow us to conclude that the dry extract of guava leaves has promising activity to be applied topically in the oral cavity or in the development of antitumor formulation or even be used as a functional food.

The Contribution of Accounting for the Definition of Performance Indicators： The Case of Higher Education Institutions

引用

Journal of Modern Accounting and Auditing 2012年第4期8卷 537-548页

作者： Carmem Pereira Leal joao Baptista Carvalho Carlos Machado-Santos UTAD University Vila Real Portugal University of Minho Braga Portugal

The influence of the New Public Management (NPM) principles in Portuguese Public Administration, particularly in higher education, has led these institutions on a path of adaptation of structures and systems in order to improve their decision-making processes. Public organizations must, at the present, to consider the strategic issues that are of vitally importance to their survival. In this context, the Balanced Scorecard (BSC), due to its intrinsic characteristics, is presented as value added in attempts to link the set of objectives with the corporate strategy; determining, a priori, a course of action that must be constantly monitored. Our research analyzes the issues underlining the development of a model of performance management based on the BSC and formatted to a higher education institution (HEI). The analysis of the results confirms the viability of applying an evaluation model constructed within a specific framework. In addition, the analysis attests the importance of performance indicators in this model of evaluation, specifically those of accounting, and consequently, the added contribution they can make in the process of decision-making within HEI, particularly, in current times when the priority is to achieve more with fewer resources.

PillCam~ SB3 capsule: Does the increased frame rate eliminate the risk of missing lesions?

引用

World Journal of Gastroenterology 2016年第10期22卷 3066-3068页

作者： Sara Monteiro Francisca Dias de Castro Pedro Boal Carvalho Maria joao Moreira Bruno Rosa José Cotter Department of Gastroenterology Hospital Senhora da Oliveira Rua dos Cutileiros Creixomil 4835-044 Guimaraes Portugal Life and Health Sciences Research Institute (ICVS) School of Health Sciences University of Minho 4710-057 Braga Portugal ICVS/3B's PT Government Associate Laboratory 4710-057 Braga/Guimaraes Portugal

Since its emergence in 2000, small bowel capsule endoscopy(SBCE) has assumed a pivotal role as an investigation method for small bowel diseases. The PillCam SB2-ex offers 12 h of battery time, 4 more than the previous version(SB2). Rahman et al recently found that the PillCam SB2-ex has a significantly increased completion rate, although without higher diagnostic yield, compared with the SB2. We would like to discuss these somewhat surprising results and the new potentialities of the PillCam SB3 regarding the diagnostic yield of small bowel studies. PillCam SB3 offers improved image resolution and faster adaptable frame rate over previous versions of SBCE. We recently compared the major duodenal papilla detection rate obtained with PillCam SB3 and SB2 as a surrogate indicator of diagnostic yield in the proximal small bowel. The PillCam SB3 had a significantly higher major duodenal papilla detection rate than the PillCam SB2(42.7% vs 24%, P = 0.015). Thus, the most recent version of the PillCam capsule, SB3, may increase diagnostic yield, particularly in the proximal segments of the small bowel.
