Desempenho de milho inoculado com Azospirillum brasiliense associado a doses de nitrogênio em cobertura.

RESUMO: Uma das alternativas de redução no consumo de fertilizantes nitrogenados na cultura do milho é a inoculação de sementes com bactérias diazotróficas que possuem a capacidade de fixar N atmosférico no solo. O objetivo deste trabalho foi avaliar algumas características agronômicas e o rendimento de grãos de milho cultivado em Latossolo Vermelho com diferentes doses de N em cobertura, na presença e ausência de inoculação de sementes com Azospirillum brasilense. Os experimentos foram conduzidos em Papanduva e em Campos Novos, SC, nos anos agrícolas 2011/12 e 2012/13, utilizando-se delineamento fatorial 2 x 6, com os tratamentos alocados em blocos casualizados, com três repetições, avaliando-se a variedade de milho de polinização aberta SCS155 Catarina. Os fatores testados foram a inoculação com A. brasilense (presença e ausência) e doses de N em cobertura (0, 25, 50, 75, 100 e 125kg ha-1). A inoculação de sementes de milho com A. brasilense não aumenta o rendimento de grãos e não altera a massa de mil grãos, estatura de plantas, altura da inserção da espiga principal e diâmetro do colmo. A aplicação de N em cobertura no milho influencia de modo positivo o rendimento de grãos. ABSTRACT: One of the alternatives to reduce the consumption of nitrogen fertilizers in corn production is seed inoculation with diazotrophic bacteria that have the ability of fixing atmospheric N in the root zone. The aim of this study was to evaluate some agronomic characteristics and grain yield of maize grown in an Oxisol with the presence and absence of seed´s inoculation with Azospirillum brasilense associated with different nitrogen doses (0, 25, 50, 75, 100 and 125kg/ha). The experiments were carried out in the municipalities of Papanduva and Campos Novos, in Santa Catarina State (Southern Brazil), during the 2011/12 and 2012/13 seasons. The experiments were ploted in a 2x6 factorial with the treatments assigned in a randomized blocks with three replications, using the corn cultivar ?SCS155 Catarina? as indicator. The inoculation of seeds with Azospirillum brasilense does not increase the corn yield and does not alter the weight of the grains, plant height, ear height and main stem diameter. Nitrogen application in corn influences positively the grain yield

Metabarcoding analysis of gut microbiota of healthy individuals reveals impact of probiotic and maltodextrin consumption

In a previously published double-blind, placebo-controlled study, we showed that probiotics intake exerted a positive effect on sleep quality and a general improvement across time in different aspects of the profile of mood state, like sadness, anger, and fatigue in 33 healthy individuals. The present work investigates the impact of the probiotic product, constituted of Limosilactobacillus fermentum LF16, Lacticaseibacillus rhamnosus LR06, Lactiplantibacillus plantarum LP01 (all former members of Lactobacillus genus), and Bifidobacterium longum 04, on the gut microbiota composition of the same cohort through a metabarcoding analysis. Both the placebo and probiotic treatments had a significant impact on the microbiota composition. Statistical analysis showed that the microbiota of the individuals could be clustered into three groups, or bacteriotypes, at the baseline, and, inherently, bacterial compositions were linked to different responses to probiotic and placebo intakes. Interestingly, L. rhamnosus and L. fermentum were retrieved in the probiotic-treated cohort, while a bifidogenic effect of maltodextrin, used as placebo, was observed. The present study shed light on the importance of defining bacteriotypes to assess the impact of interventions on the gut microbiota and allowed to reveal microbial components which could be related to positive effects (i.e. sleep quality improvement) to be verified in further studies

A Comparative Study of the Triglycerides/HDL Ratio and Pseudocholinesterase Levels in Patients with Bladder Cancer

Background: Lipid alterations may serve as potential tumour biomarkers. The ratio of triglycerides to HDL cholesterol (TG/HDL ratio) is associated with various cancers. Pseudocholinesterase (PChE) activity, involved in TG hydrolysis, plays an important role in the metabolism of lipoprotein. There is scarce data assessing the reliability of both the TG/HDL ratio and PChE levels in correctly classifying patients suffering from bladder cancer. Methods: Three hundred and ninety-six patients undergoing cystoscopy or transurethral resection of the bladder (TURB), broken into two major groups, i.e., patients with histologically confirmed, non-metastatic bladder cancer (n = 208) and without bladder cancer (no bladder cancer, n = 188), formed the study population. The last group was split into two subgroups consisting of a cohort of patients never suffering from bladder cancer but with other bladder diseases (no CaBD, n = 100) and another cohort formed by patients characterised by eradicated bladder cancer after TURB with no recurrence during a three-month follow-up (previous bladder cancer, n = 88). Pieces of information by both metabolic derangement (the presence of type 2 diabetes mellitus), hypertension and lipid profile were retrieved from patient records upon entry to the study. Sensitivity, specificity, areas under the ROC (AUROC) of the TG/HDL ratio, and PChE levels were used in diagnostic decision making. Results: The TG/HDL ratio as well as PChE concentrations of bladder cancer patients were significantly different when compared to those with previous bladder cancer and the no CaBD patients (p = 0.023 and 0.0004, respectively). There was an independent role of both the TG/HDL ratio and PChE levels in predicting the presence of bladder cancer (OR: 1.22 and 0.99, respectively), but the reliability of the TG/HDL ratio (AUROC: 0.587) was superior to that of PChE levels (AUROC: 0.374). The AUROC of a new parameter resulting from the combination of the TG/HDL ratio with PChE levels showed a further increment in the discriminant power of the bladder cancer presence (0.6298), interestingly with a negative predictive value (89%) according to the Bayesian approach. The cut-off of the TG/HDL ratio, the main marker of the present study that better distinguishes bladder cancer from no bladder cancer patients, was 2.147. Discussion and Conclusions: The reliability of the TG/HDL ratio is based on the fact that this parameter likely mirrors the insulin resistance (IR) underlying bladder cancer patients. Furthermore, PChE levels evidence both IR and the associated non-alcoholic fatty liver disease. The TG/HDL ratio and PChE levels as well as their combined use could help physicians to assess/confirm the presence of this very common cancer, where early detection is important to ensure the best therapeutical approach

Metabolomic Approaches for Detection and Identification of Biomarkers and Altered Pathways in Bladder Cancer

Metabolomic analysis has proven to be a useful tool in biomarker discovery and the molecular classification of cancers. In order to find new biomarkers, and to better understand its pathological behavior, bladder cancer also has been studied using a metabolomics approach. In this article, we review the literature on metabolomic studies of bladder cancer, focusing on the different available samples (urine, blood, tissue samples) used to perform the studies and their relative findings. Moreover, the multi-omic approach in bladder cancer research has found novel insights into its metabolic behavior, providing excellent start-points for new diagnostic and therapeutic strategies. Metabolomics data analysis can lead to the discovery of a “signature pathway” associated with the progression of bladder cancer; this aspect could be potentially valuable in predictions of clinical outcomes and the introduction of new treatments. However, further studies are needed to give stronger evidence and to make these tools feasible for use in clinical practice
