Utilização de tecnologia alternativa para coleta de material meristemático de bananeira para estabelecimento in vitro.

Em Rondônia, a banana é a fruta de maior importância econômica e a mais produzida no Estado. Em 2006, em uma área de 5.401 ha, foram produzidas 46.117 toneladas Os principais municípios produtores são Buritis, Cacoal e Porto Velho, respectivamente. No entanto, a bananicultura no Estado enfrenta alguns problemas agrícolas: alta incidência de pragas e doenças (moleque, nematóides, mal do Panamá, Sigatokas negra e amarela, com maior destaque para a Sigatoka negra), baixo nível de tecnologia utilizado na produção e na pós-colheita e falta de capacitação dos agentes da cadeia produtiva. Assim, a seleção de variedades mostra-se como uma forma eficaz no combate a pragas e doenças. Neste sentido, o objetivo deste trabalho foi testar uma tecnologia alternativa para tornar mais simples e eficiente o processo de coleta e estabelecimento de explantes de bananeiras, contribuindo com a produção de mudas em sistemas de produção via cultura de tecidos vegetais.bitstream/CPAF-RO-2010/13267/1/ct101-banana.pd

Transient elastography and APRI score: looking at false positives and false negatives. Diagnostic performance and association to fibrosis staging in chronic hepatitis C

Although long regarded as the gold standard for liver fibrosis staging in chronic hepatitis C (CHC), liver biopsy (LB) implies both the risk of an invasive procedure and significant variability. The aim of this study was to evaluate the diagnostic performance for transient elastography (TE) and aspartate aminotransferase to platelet index (APRI) used alone and in combination compared to liver biopsy and to analyze false positive/negative results. Patients with CHC, and no previous clinical diagnosis of cirrhosis were enrolled to undergo liver biopsy, TE and APRI. A total of 182 adult patients with a median age of 55 years and median body mass index of 26.71 kg/m2 were analyzed. On LB, 56% of patients had significant levels of fibrosis (METAVIR F≥2) and 28% had advanced fibrosis (F3/F4). The strongest performance for both tests was observed for exclusion of advanced fibrosis with good negative predictive values (89 and 86%, respectively). Low necroinflammatory activity on LB was associated with false negative TE. False positives were associated with NASH and smaller LB fragments. Correlation between APRI and Fibroscan for F≥2 was 100% and 84% for F≥3 and remained high in both false negative and false positive instances, correctly identifying F<2 in 71% of cases and F<3 in 78% (and potentially foregoing up to 84% of LB). We concluded that low individual performance indicators could be attributable to limitations of LB. Poorer differentiation of lower levels of fibrosis is a known issue for LB and remains so for noninvasive tests. Good predictability is possible, however, for advanced fibrosis4991

Effects of Horizontal and Incline Bench Press on Neuromuscular Adaptations in Untrained Young Men

International Journal of Exercise Science 13(6): 859-872, 2020. The aim of the current study was to investigate the effects of horizontal and incline bench press as well as the combination of both exercises on neuromuscular adaptation in untrained young men. Forty-seven untrained men were randomly assigned to one of the three groups: 1) a horizontal bench press group (n= 15), 2) an incline bench press group (n= 15), and 3) a combination (horizontal + incline) group (n= 17). Training was conducted once a week for eight weeks, with equalized number of sets among groups. Muscle thickness, isometric strength and electromyography (EMG) amplitude of the pectoralis major were measured one week before and after the training period. There was no difference between groups for the change in horizontal bench press isometric strength (~ 10 kg increase, p=0.776) or incline bench press isometric strength (~ 11 kg increase, p=0.333). Changes in muscle thickness differed only in one of the three sites. The changes in the second intercostal space of the pectoralis major was greatest in the incline pressure group compared with the horizontal [mean difference (95% CI) of 0.62 (0.23, 1.0) cm, p=0.003] and combination groups [mean difference (95% CI) of 0.50 (0.14, 0.86) cm, p=0.008]. The change in EMG amplitude following training differed between groups in only one out of the four sites. The present results indicate that strength and conditioning professionals might consider that horizontal and incline bench press exercises, or a combination of both exercises can render similar change in general strength
