title: Using palynological evidence from royal jelly to mediate the spread of Paenibacillus larvae in Brazil

description: ABSTRACT Royal jelly may contain pollen grains and their presence can be used to determine the phytogeographical origin of the product. This study analyzed the phytogeographical origin of commercial royal jelly samples from São Paulo State, tested as part of the Brazilian Federal Inspection System (SIF), found to be contaminated with spores of the bacterium Paenibacillus larvae, that causes the American Foulbrood Disease. The pollen grains of Castanea had the highest total percentage, with lower percentages of Cirsium/Carduus, Cistus, Parthenocissus, Prunus, Quercus, Robinia, Scrophulariaceae, Taraxacum, Tilia, among others. This pollen spectrum is incompatible with royal jelly samples produced in Brazil. The pollen spectrum resembled that of an imported product, compatible with the Northern Hemisphere origin. Brazilian legislation does not require the phytogeographic origin of imported bee products to be analyzed by palynological procedures, but it is mandatory to have a certificate issued by the country of origin attesting the absence of pathogens, monitored with the objective of preventing the exotic diseases from entering Brazil. Palynology, therefore, proved to be fundamental in detecting imports of this contaminated batches.

title: The Behavior of CPW-Fed Sierpinski Curve Fractal Antenna

description: Abstract In this paper, the behavior of Coplanar Waveguide (CPW) fed SIERPINSKI curve fractal antenna is studied. The results show that there is a relationship between the iteration number and the resonance frequencies. With increase in the number of iteration the resonance frequency decreases with a constant ratio. The use of fractal structures to design antennas makes them more miniaturized. The simulated results obtained from CADFEKO a Method of Moments (MoM) model based Solver and measurement using Vector Network Analyzer Anritsu MS2026C are in good agreement.

title: A technical note on low cost rat laparoscopy an initial experience

description: Abstract Purpose: To evaluate a novel and adapted low-cost set model for laparoscopic surgery in rats. Methods: Nine Wistar rats underwent two different laparoscopic procedures, splenectomy (n=3) and distal pancreatectomy with splenectomy (n = 6), after assembling a low-cost set replacing the conventional one (monitor, micro camera, image processor, light source, laparoscope and insufflator). The new set included an Android Tablet 10.5 ", a 5mm USB Endoscope and semiautomatic sphygmomanometer monitor. Results: The same surgeon performed the laparoscopic procedures. Total surgical time ranged from 36 to 60 minutes with a mean of 45.8 minutes. Three rats died during the distal pancreatic and splenectomy procedure (33.3%), due to respiratory failure (n = 1), uncontrolled abdominal hemorrhage (n=1) and iatrogenic gastric perforation (n = 1). We followed the other six rats (66.6%) for seven days with no further evidence of complications. Conclusions: The laparoscopic partial pancreatectomy and splenectomy can be performed with the novel low-cost set assembled in the present experimental study. Both specific training and skills development are required to validate more advanced laparoscopic procedures and achieve a desirable outcome.

title: Genetic improvement of horticultural crops mediated by CRISPR/Cas: a new horizon of possibilities

description: ABSTRACT The burden of the current global challenge involving food security lies in the need to improve crop production. In this regard, biotechnology stands out as an essential tool to generate plants able to cope with pests, diseases, and harsh climatic conditions, and more efficient in the use of natural resources. An advanced approach to create genetic variability in a precise and targeted way, the genome-editing technique CRISPR/Cas (clustered regularly interspaced short palindromic repeats/CRISPR associated proteins), has drawn the attention of breeders. The genome editing CRISPR/Cas system relies on a guiding RNA that directs a nuclease to generate a double-strand break (DSB) at a target DNA, activating the cell repair systems and eventually leading to deletions or insertions of nucleotides. Therefore, CRISPR/Cas is a toolbox to achieve many goals, from basic science investigations to the development of crops with improved agronomic traits, with potential to bring innovative solutions to food production. The CRISPR/Cas system has been applied in a large number of plants, including some horticultural species. In this review, we present details of the CRISPR/Cas natural and artificial systems, its possibilities as a biotechnological tool, advantages over other breeding techniques, regulatory issues, and its applicability in horticultural crops, as well as future challenges.

title: Effects of Adding Organic Matter to a Red-Yellow Latosol in the Sorption and Desorption of Tebuthiuron

description: ABSTRACT: Tebuthiuron is one of the most widely used herbicides in the sugarcane culture and its characteristic is the long persistence in soil. When used without knowing its interactions with soil attributes, it can reduce the sustainability of cropping systems and contaminate surface and groundwaters. In this research, by using a high-performance liquid chromatography, the effects of adding organic matter in a Red-Yellow Latosol were evaluated, as for the sorption and desorption of tebuthiuron. It was concluded that there is a direct relation between the sorption of tebuthiuron and the organic matter content in Red-Yellow Latosols and there is an inverse relation for desorption. The hysteresis index was lower in samples with high organic matter content.

title: Irrigation as an alternative to reduce damages caused by defoliation of sweet corn

description: ABSTRACT Reduction of leaf area significantly affects maize productivity, due to its low plasticity. Thus, appropriate water application can minimize this problem, considering that under favorable water conditions the plant would express its maximum production potential. The aim of this study was to evaluate the influence of irrigation on the productive performance of sweet corn submitted to different defoliation levels at the beginning of crop cycle. The experimental design was a randomized block design, arranged in split plot scheme; plots consisting of four water depths [50, 75, 100 and 125% of crop evapotranspiration (ETc)] and the subplots consisted of three defoliation levels [0% (control); 35% (removal of four fully expanded leaves), 100% (total removal of leaves, shoot section)], with three replicates. The use of irrigation has a positive influence on recovery of damages caused by defoliation at the initial development stages of sweet corn, and the success of irrigation management, as a strategy to mitigate damages caused by defoliation, depends on the level of the lost leaf area and the amount of water used.

title: Phosphate fertilization influences macronutrient accumulation in watermelon cv Magnum

description: ABSTRACT Studies on nutrient uptake are important to understand nutritional needs of crops, which demand may also be influenced by fertilization management, particularly P fertilization. Thus, the aim of this study was to evaluate macronutrient accumulation and distribution in watermelon cv. Magnum, under two forms of phosphate fertilization. The experiment was carried out in a sandy-textured Argisol in Mossoró-RN. The experimental design was a randomized block design, arranged in split plot in time, with four replicates. We evaluated dose of 137 kg ha-1 of P2O5 under two forms of fertilization [pre-planting (F0) and pre-planting + topdressing (F1)]. Triple superphosphate (SFT) was used for pre-planting applications and topdressing applications were done through fertigation using monoammonium phosphate (MAP, 34 kg ha-1 of P2O5). Shoot samples (stem + leaf + fruit) of the experimental plots were collected at 27, 34, 40 and 55 days after emergence (DAE), and quantitative values of the accumulated nutrients were determined. In general, the highest accumulation of macronutrients occurred in the last third of the crop cycle. General accumulation of macronutrient was altered by fertilization form. An increase in P accumulation was observed using F1 fertilization, both in total and in fruits. Macronutrient accumulation rates increased during the evaluation period, except for Ca and Mg in F1 fertilization. F1 fertilization provided higher total accumulations of Ca and Mg, but the same did not occur for the accumulation in fruits.

title: Performance of processing tomatoes under different supply levels of crop evapotranspiration

description: ABSTRACT Irrigation management is essential to promote appropriate plant growth and guarantee production and quality of the tomatoes for processing, increases the efficiency of nutrients use and contributes to ensure the sustainability of the production chain. This study was installed to evaluate productive performance of two processing tomato hybrids submitted to five water depths under drip irrigation system. Five levels of crop evapotranspiration (ETc) replacement (60%, 100%, 140%, 180% and 220%) and two tomato hybrids (BRS Sena and H 9992) were tested. The experimental design was a 5×2 factorial arranged in randomized complete block design with four replications. During the crop cycle, hybrids BRS Sena and H 9992 needed 692.20 and 418.43 mm of water, yielding 80 and 44.06 t ha-1, respectively. For both hybrids, the higher water productivity was observed when lower levels of irrigation were applied. Higher productivities and pulp yields of ‘BRS Sena’ and ‘H 9992’ were noticed when replacing 150-166% and 99-101% ETc, respectively. We observed that improving the performance of processing hybrid tomatoes is possible by adjusting irrigation levels for each hybrid according to growing conditions.

title: Tolerance of Annual Winter Species to Protoporfirinogen Oxidase Inhibiting Herbicides (Protox)

description: ABSTRACT: The use of plant species for the phytoremediation of soils contaminated with herbicides is an alternative that has been emphasized to minimize the effects of the persistence of agrochemicals in the environment. The objective of this study was to evaluate the tolerance potential of winter species in soils contaminated with sulfentrazone and fomesafen. The experiment was in a completely randomized design with four replications. Doses of fomesafen (0.0, 0.125, 0.250, and 0.5 kg ha-1) and sulfentrazone (0.0, 0.3, 0.6 and 1.2 kg ha-1) were applied during the pre-emergence of phytoremediate species (black oat, vetch, birdsfood trefoil, radish and lupin). Forty five days after the emergence of the species, the phytotoxicity (%), leaf area (cm2), stalk and/or stem diameter (mm), height (cm) and dry matter (g) variables of the plants were evaluated. Data were submitted to analysis of variance by F test; when significant, linear or non linear regressions were applied to evaluate the effect of herbicide doses on the studied species. Birdsfood trefoil was the less tolerant species to fomesafen and sulfentrazone. Black oat was less affected by the application of fomesafen doses, but it was highly susceptible to sulfentrazone. Radish presented tolerance only up to the fomesafen dose of 0.25 kg ha-1; as for sulfentrazone, the species showed tolerance. The most tolerant species to fomesafen and sulfentrazone, regardless of the dose, was the lupine, which is a possible alternative for the phytoremediation of soils contaminated with these herbicides.

title: Hyperbaric oxygenation on adhesions prevention after laparotomy in rats

description: Abstract Purpose: To evaluate the effects of hyperbaric oxygenation on prevention of adhesions in the abdominal cavity after laparotomy. Methods: Fifty four rats underwent laparotomy; stitches were made in the four quadrant parietal peritoneum and abdominal cavity closure. Animals were divided into three groups: 1 - control; 2 - subjected to high pressures and oxygenation; 3 - subjected to 100% hyperbaric oxygenation. The animals in groups 2 and 3 were daily submitted to oxygenation hyperbaric chamber after surgery. On the seventh day another laparotomy, registration of procedure, assessment of adhesions and biopsies of the peritoneum were held. Professionals analyzed the videos and the biopsies. Results: Peritoneal cavity adhesions occurred in animals of three groups with no difference between them. In Group 3, the adhesions presented more fragile and vascular proliferation more pronounced, and there was no difference in comparison with the first and second groups. However, there was no significant difference in the evaluation of these parameters between the animals in groups 1 and 2. Conclusions: Postoperative hyperbaric oxygenation in rats submitted to laparotomy did not alter the frequency, but reduced the density of adhesions in the peritoneal cavity and promoted vascular proliferation. The change in atmospheric pressure alone had no influence on the results.
