TOXIDEZ POR ÁCIDOS ORGÂNICOS EM GENÓTIPOS DE ARROZ IRRIGADO

The soils flooded for lowland rice crop promote anaerobiosis conditions and low molecular weight organic aliphatic acids are produced and affect the rice crop by toxicity. This study was carried out to evaluate the organic acids effects in nutrient solution on lowland rice crop genotypes root and shoot growth recommended in Rio Grande do Sul State. The study was developed under controlled conditions (growth chamber) in the Plant Nutrition Laboratory at UFPel/FAEM/DS. A factorial statistical design 4x3 with 4 replicates was used. The following organic acids treatments were tested: zero; acetic acid 5.0 mmol dm-3; propionic acid 1.25 mmol dm-3; and butyric acid 1.0 mmol dm-3. Rice seedlings of genotypes EMBRAPA BRS-7 TAIM, IRGA 417 and EMBRAPA BRS PELOTA with 3 cm of root growth were put inside test tubes for 13 days with complete nutrient solution and organic acids. The effect of the organic acids was bigger in roots that those rice shoot; the PELOTA genotype was superior to that those genotypes in presence of organic acids, mainly butyric acid; the genotypes did not differed among them.O alagamento do solo para o cultivo do arroz irrigado promove condições de anaerobiose, produzindo ácidos orgânicos alifáticos de cadeia curta, que são tóxicos ao arroz. Com o objetivo de comparar o efeito dos ácidos acético, propiônico e butírico, em solução nutritiva, sobre o crescimento radicular e da parte aérea de três genótipos de arroz irrigado recomendados no Rio Grande do Sul, foi desenvolvido um experimento em condições controladas no Laboratório de Nutrição de Plantas da UFPel/FAEM/DS. Utilizou-se um delineamento fatorial 4x3 com 4 repetições, onde foram testados os seguintes tratamentos com ácidos orgânicos: testemunha, 5,00 mmol dm-3 de ácido acético; 1,25 mmol dm-3 de ácido propiônico e 1,00 mmol dm-3 de ácido butírico. Plântulas de arroz das cultivares EMBRAPA BRS - 7 TAIM, IRGA 417 e EMBRAPA BRS PELOTA com aproximadamente 3 cm de radícula, foram colocadas por treze dias em tubos de ensaio contendo solução nutritiva completa e ácidos orgânicos. O efeito dos ácidos orgânicos foi maior nas raízes do que na parte aérea; a cultivar PELOTA foi superior que as demais na presença de ácidos orgânicos, principalmente o ácido butírico; e dentro da cultivar, não houve diferença significativa entre os mesmos

Osteonecrosis of the jaw induced by receptor activator of nuclear factor-kappa B ligand (Denosumab): review

Background: Denosumab, an anti-resorptive agent, IgG2 monoclonal antibody for human Receptor activator of nuclear factor-kappa B ligand (RANKL), has been related to the occurrence of osteonecrosis of the jaws. Thus, the aim of this study was to review the literature from clinical case reports, regarding the type of patient and the therapeutic approach used for osteonecrosis of the jaws induced by chronic use of Denosumab. Material and Methods: For this, a literature review was performed on PubMed, Medline and Cochrane databases, using the keywords “Denosumab” “anti-RANK ligand” and “Osteonecrosis of jaw”. To be included, articles should be a report or a serie of clinical cases, describing patients aged 18 years or over who used denosumab therapy and have received any therapy for ONJ. Results: Thirteen complete articles were selected for this review, totaling 17 clinical cases. The majority of ONJ cases, patients receiving Denosumab as treatment for osteoporosis and prostate cancer therapy. In most cases, patients affected by ONJ were women aged 60 or over and posterior mandible area was the main site of involvement. Diabetes pre-treatment with bisphosphonates and exodontia were the most often risk factors related to the occurrence of this condition. Systemic and local antibiotic therapy with or without surgical debridement was the most used treatment for ONJ resolution. Conclusions: It is concluded that the highest number of ONJ cases caused by the use of anti-RANKL agents occurred in female patients, aged 60 years or older, under treatment for osteoporosis and cancer metastasis, and the most affected region was the mandible posterior

Nitrogen Fertilization in Blackberry

Nutrition studies for blackberry crop are scarce worldwide. This chapter presents several aspects of nitrogen (N) in blackberry (Rubus spp.) nutrition. Soil characteristics that can influence nitrogen fertilization are the large discrepancies in the rates recommended in the literature, forms and times of application, sources of nitrogen, differences between cultivars and the main symptoms of N deficiency. The impact of moderate and severe nitrogen deficiency on vegetative growth and yield of ‘Tupy’ blackberry is also presented. In addition, a nitrogen fertilization recommendation system is proposed, based on the organic matter content of the soil, the age of the plants, and the expected productivity of the cultivars

Eficiência do fosfato natural para o arroz irrigado em solo do sul do Brasil

Phosphate rock efficiency to lowland rice was evaluated in a study that we tested: a) phosphorus sources (P): 1- triple superphosphate (TSP); 2-Phosphate rock (PR); and b) phosphorus rates: 0, 10, 20, 40 and 80 mg kg-1. Rice variety EMBRAPA 7 "TAIM", was grown in a pot for thirty days. Soil solution pH values were similar between rates for the same source; however, the PR was superior to TSP in both soil solution sampling. The P concentrations in solution increased according to P rates. P amounts in the second soil solution sampling were similar between rates of the same source, but the differences were observed at P (TST) rate of 80 mg kg-1. Shoot dry matter increased with P rate and the 80 mg kg-1 P rate was superior in both sources. However, the TSP was superior to PR and this tendency was similar with the P in plant tissue and P uptake by plants. P in soil solution, P plant content, P uptake by plants and rice growth increased according to P applied in soil; PR showed high agronomic efficiency at rates over 40 mg kg-1 de P.Com o objetivo de avaliar a eficiência do fosfato natural na cultura do arroz irrigado, foi desenvolvido um experimento onde testou-se: a) fontes de fósforo(P) : 1- Superfosfato triplo (SFT); 2- Fosfato natural (FN); e b) Doses de P: 0, 10, 20, 40 e 80 mg kg-1. Arroz da cultivar EMBRAPA 7 "TAIM", foram cultivadas em vasos durante trinta dias. O pH na solução do solo não diferiu entre as doses na mesma fonte. O P na solução aumentou com o acréscimo das doses de P, porém na primeira coleta não diferiu entre as fontes. Na segunda coleta os teores de P foram similares nas diferentes doses para a mesma fonte, diferindo apenas no SFT na dose de 80 mg kg-1. A produção de matéria seca aumentou conforme a dose de P sendo que a dose de 80 mg kg-1 foi superior nas duas fontes. Os teores de P na solução do solo e na planta, a quantidade acumulada de P e a produção de matéria seca do arroz, aumentaram com o acréscimo das doses de P aplicadas ao solo; o fosfato natural apresentou alta eficiência agronômica a partir de doses equivalentes à 40 mg kg-1 de P

Association Of Inflammation, Dyslipidemia, Obesity And Physical Activity Status In Children

The aim of this study was to verify the association between inflammatory biomarkers, dyslipidemia, obesity and physical activity status in 10-years old children. Ninety-four children participated in this study and were classified into eutrophic (n=36), overweight (n=34) or obese (n=24) according to their body mass index (BMI). The genic expression of interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-α) and chemokine C-C motif ligand 2 (CCL-2) mRNA; the serum concentration of high-density lipoprotein cholesterol (HDL-c) and triglycerides; BMI, percentage of body fat (% BF) and waist circumference; and the number of steps per day were determined. The expression of IL-6, TNF-α and CCL-2 were associated (p 0.05) between pro-inflammatory biomarkers and number of steps per day was found.222182

Multimorbidity and complex multimorbidity in Brazilians with severe obesity

To investigate the prevalence of multimorbidity and complex multimorbidity and their association with sociodemographic and health variables in individuals with severe obesity. This is a baseline data analysis of 150 individuals with severe obesity (body mass index ≥ 35.0 kg/m2) aged 18-65 years. The outcomes were multimorbidity and complex multimorbidity. Sociodemographic, lifestyle, anthropometric and self-perceived health data were collected. Poisson multiple regression was conducted to identify multimorbidity risk factors. The frequency of two or more morbidities was 90.7%, three or more morbidities was 76.7%, and complex multimorbidity was 72.0%. Living with four or more household residents was associated with ≥ 3 morbidities and complex multimorbidity. Fair and very poor self-perceived health was associated with ≥ 2 morbidities, ≥ 3 morbidities and complex multimorbidity. A higher BMI range (45.0-65.0 kg/m2) was associated with ≥ 2 morbidities and ≥ 3 morbidities. Anxiety (82.7%), varicose veins of lower limbs (58.7%), hypertension (56.0%) were the most frequent morbidities, as well as the pairs and triads including them. The prevalence of multimorbidity and complex multimorbidity in individuals with severe obesity was higher and the risk for multimorbidity and complex multimorbidity increased in individuals living in households of four or more residents, with fair or poor/very poor self-perceived health and with a higher BMI

Occupational accidents : social insurance costs and work days lost

OBJETIVO: Estimar a contribuição de benefícios concedidos por acidentes de trabalho dentre o total de benefícios relacionados com a saúde da Previdência Social, focalizando os custos conforme o tipo de benefício, e o impacto sobre a produtividade relativa a dias perdidos de trabalho. MÉTODOS: Utilizam-se registros dos despachos de benefícios do Sistema Único de Benefícios do Instituto Nacional de Seguridade Social da Bahia, em 2000. Acidentes de trabalho foram definidos com o diagnóstico clínico para Causas Externas, Lesões e Envenenamentos (SS-00 a T99) da Classificação Internacional de Doenças 10ª Revisão, e o tipo de benefício que distingue problemas de saúde ocupacionais e não ocupacionais. RESULTADOS: Foram estudados 31.096 benefícios concedidos por doenças ou agravos à saúde, dos quais 2.857 (7,3%) eram devidos a acidentes de trabalho. Maiores proporções foram estimadas entre os trabalhadores da indústria da transformação e construção/eletricidade/gás, 18% do total dos benefícios. Os custos com os benefícios para acidentes de trabalho foram estimados em R$8,5 milhões, com aproximadamente meio milhão de dias perdidos de trabalho no ano. CONCLUSÕES: Apesar do conhecimento de que esses dados são sub-enumerados, e restritos aos trabalhadores que conseguiram receber benefícios relacionados com a saúde, os achados revelam o grande impacto sobre a produtividade e o orçamento do Instituto Nacional de Previdência Social de agravos reconhecidos como evitáveis, reforçando a necessidade de sua prevenção.OBJECTIVE: To estimate the proportion of occupational accident benefits granted within the total for health-related social security benefits, viewing the costs according to benefit type and the impact on productivity according to work days lost. METHODS: Records of benefit decisions from the National Benefits System of the National Social Security Institute for the State of Bahia in 2000 were utilized. Occupational accidents were defined in accordance with the clinical diagnoses of External Causes, Injuries and Poisoning (SS-00 to T99) of the International Classification of Diseases, 10th Revision, and with the benefit type, which distinguishes between occupational and non-occupational health problems. RESULTS: A total of 31,096 benefits granted due to illnesses or health problems were studied. Of these, 2,857 (7.3$8.5 million, with around half a million work days lost during the year studied. CONCLUSIONS: Despite the fact that these data are under-reported and are restricted to workers who were able to receive health-related benefits, the findings reveal that avoidable health problems have a major impact on productivity and on the budget of the National Social Security Institute, thereby reinforcing the need for their prevention

Generation WAVY: a new breed of surface drifters for all ocean domains

A new family of multi-purpose, multi-sensor, small sized, easy-to-handle, low-cost, spherical surface drifters is about to appear in the market, with its first three models. The WAVY Ocean is a current, wave and near-surface temperature gradient tracker for the open Ocean; the WAVY Littoral is a current and wave tracker designed for nearshore operations; and the WAVY Basic is a current and nearsurface temperature tracker intended for riverine and estuarine environments, and suitable for citizen science. The WAVY optimized buoyancy - only 30% of the axes above the surface - ensures that their displacement is essentially due to the current, while their small size makes them sensitive to the average vectors in the very near surface. Examples of WAVY Ocean full resolution data from recent observations illustrate the performance and the potential of these drifters in operational missions requiring near-real time data of the very near surface of the ocean.This is a contribution to Project MELOA (Multipurpose/Multi-sensor Extra Light Oceanography Apparatus - H2020-SC5-2017-OneStageB).
