title: Burndown herbicides in Crambe abyssinica crops: seed yield and quality

description: ABSTRACT The application of burndown herbicides to crambe crops is important for production of quality seeds. The objective of this work was to evaluate the effect of burndown herbicides applied at pre-harvest, using different spray volumes, on seed yield and quality of crambe plants (Crambe abyssinica cv. FMS Brilhante). A randomized block experimental design was used, with four replications, in a 2 × 5 factorial arrangement consisted of two burndown herbicides [glyphosate (Roundup Original 360 g L-1) and diquat (Reglone 200 g L-1)] and five spray volumes (0.0, 0.5, 1.0, 1.5, and 2.0 L ha-1). The burndown herbicides were applied at 74 days after sowing, when the plants presented 80% brown seeds, based on visual evaluation of the seed maturation stage. After harvest, the seeds were processed and evaluated for water content, one-thousand seed weight, seed yield, oil contents, germination, and vigor (first germination counting, emergence speed index, accelerated aging, and electrical conductivity). The pre-harvest desiccation of crambe with the herbicide diquat, using spray volumes between 1.3 and 1.5 L ha-1, resulted in seeds with better physiological quality. The seed vigor was low when using desiccation of plants with glyphosate. The crop yield was not affected by the herbicides nor by the different spray volumes.

title: Development of a portable multisensor platform for soil mapping

description: ABSTRACT Soil sensors are alternatively used to reduce the costs of soil sampling and be able to perform analyses in a laboratory. However, using individual sensors can result in low accuracy because the measured variable may be related to more than one soil characteristics. This study aimed to develop a portable soil multisensor platform with sensors for apparent electrical conductivity, moisture, temperature, and penetration resistance of the soil. The multisensor platform was developed based on a BeagleBone Black (BBB) single-board computer. Electronic circuits have been developed for electrical conductivity and moisture sensors. A load cell was used in the soil-penetration resistance sensor. For validation, the ECa, soil moisture, and penetration resistance data obtained using the multisensor platform and commercial sensors were compared. A low-cost global navigation satellite system module was used to georeference sampling points. The cost of acquiring the components required to assemble the multisensor platform was US$ 361.94. The strong correlation between the data obtained with the multisensor platform and commercial sensors proves that the developed multisensor platform has acceptable accuracy. The spatial variability of the apparent soil electrical conductivity, moisture, temperature, and penetration resistance in a coffee plantation can be characterized by the generated maps from the data obtained by the four sensors.

title: Wheat grain biofortification for essential amino acids

description: Abstract The objective of this work was to select wheat genotypes aiming to increase the essential amino acids in their grains. The study was carried out in the 2019 crop year, in a randomized complete block design, organized in a 5x5 factorial arrangement – five environments in the state of Rio Grande do Sul, Brazil (Cachoeira do Sul, Cruz Alta, Santo Augusto, São Gabriel, and Vacaria), and five wheat genotypes ('BRS Parrudo', 'Marfim', 'Quartzo', 'TBIO Mestre', and 'TBIO Sinuelo') –, with two replicates. Polar metabolites were extracted from the flour of the ground wheat grains, derivatized, and evaluated by gas chromatography-mass spectrometry. Both variance components and genetic parameters were estimated for the metabolites. To select the genotypes for the traits of interest, the multi-trait index based on factor analysis and ideotype design, the multi-trait genotype-ideotype distance index, and the multi-trait stability index were applied. The wheat genotypes express a high genetic variability and selection possibility for gentiobiose, butyric acid, galactopyranosyl, phenylalanine, tryptophan, leucine, and isoleucine. The 'Marfim' genotype remains stable for essential amino acid levels in the studied environments. The 'Quartzo' genotype stands out in the expression of leucine, isoleucine, phenylalanine, and tryptophan in its grains.

title: Pathological and Immunohistochemical Examinations in Chukar Partridge (Alectoris chukar) of Wild and Captive Populations

description: ABSTRACT The aim of this study was to evaluate the health situation of chukar partridges through several diagnostic methods. We investigated a total of 224 birds in eighteen populations throughout Turkey, fourteen wild and four captive. The molecular sexing method was used for gender identification. Clinically, traumatic lesions and inflammatory reactions were the most commonly observed in the eyes and extremities of the Chukar Partridges in the breeding stations. At necropsy, the most common findings were enteritis and liver lesions. At the histopathological examination, pneumonia, anthracosis, and inflammatory changes in the digestive system were among the common findings. Interestingly, liver parasites were found in wild samples. At the immunohistochemical examinations, the tissues were evaluated for Marek’s disease (MD), Adenovirus, Avian mycobacteriosis (AMB), and Aspergillosis. While MD and AMB were not found in breeding stations, we determined them from wild populations. Aspergillus was found in both wild and captive populations; Adenovirus antigens were found only in breeding stations. When the captive and wild populations were evaluated together, MD 1.3%, AMB 0.9%, Aspergillosis 1.3%, Adenovirus 1.8% were found. The relation between sex and diseases was also examined. As a result, the data of this study showed that chukar partridges from both breeding stations and wild populations are not an important source of diseases, but especially released partridges from breeding stations may carry some microorganisms. For that reason, captive populations should be regularly monitored for contagious diseases.

title: Analysis of virome by high-throughput sequencing disclosed multiple infection in a single grapevine plant

description: ABSTRACT: Among phytosanitary problems of the grapevine, viruses stand out for their capacity of reducing the quality and yield of grapes. However, detecting and identifying viral infections in grapevines can be challenging. This study performed a high throughput sequencing (HTS) of the viral pathogens present in a vine showing virus-like symptoms to elucidate the etiology. HTS analysis reported in a hybrid grapevine with mild curling down of leaf edges, the presence of four viruses and viroids, which were probably implicated in the observed symptoms. The determined complete genomes showed high genetic identities with previously characterized isolates of homologous pathogens.

title: The Neuroprotective Effects of Ginsenoside Rd Pretreatment in a Rat Model of Spinal Cord Ischemia-Reperfusion Injury

description: ABSTRACT Introduction: Paraplegia may develop as a result of spinal cord ischemia-reperfusion injury in patients who underwent thoracoabdominal aortic surgery. The objective of this research is to determine the neuroprotective effects of ginsenoside Rd pretreatment in a rat model of spinal cord ischemia-reperfusion injury. Methods: Sprague-Dawley rats (n=36) were randomly assigned to three groups. The sham (n=12) and control (n=12) groups received normal saline orally. The Rd group (n=12) received ginsenoside Rd (100 mg/kg) orally 48 hours before the induction of spinal cord ischemia. Spinal cord ischemia was induced by aortic occlusion using a Fogarty balloon catheter in the Rd and control groups. A neurological assessment according to the motor deficit index and a histological evaluation of the spinal cord were performed. To evaluate the antioxidant activity of ginsenoside Rd, malondialdehyde levels and superoxide dismutase activity were determined. Further, the tissue levels of tumor necrosis factor-alpha and interleukin-1 beta were measured. Results: The Rd group showed significantly lower motor deficit index scores than did the control group throughout the entire experimental period (P&lt;0.001). The Rd group demonstrated significantly greater numbers of normal motor neurons than did the control group (P=0.039). The Rd group exhibited decreased malondialdehyde levels (P&lt;0.001) and increased superoxide dismutase activity (P=0.029) compared to the control group. Tumor necrosis factor-alpha and interleukin-1 beta tissue levels were significantly decreased in the Rd group (P&lt;0.001). Conclusion: Ginsenoside Rd pretreatment may be a promising treatment to prevent ischemia-reperfusion injury in patients who undergo thoracoabdominal aortic surgery.

title: Percutaneous treatment of simple renal cysts with 24-h-interval ethanol sclerotherapy

description: Abstract Objective: To investigate the efficacy of 24-h interval multiple-session ethanol sclerotherapy for the treatment of simple renal cysts. Materials and Methods: The study sample included 58 patients (mean age, 65.37 ± 11.95 years). We included 76 simple renal cysts that were treated with percutaneous aspiration with a minimum of two sessions of 95% ethanol sclerotherapy in a 24-h interval between sessions. Patients were evaluated at 1, 3, and 6 months after the intervention for the efficacy of the treatment. Treatment success was defined as a complete regression of a cyst or a &gt; 50% reduction in its volume, with no recurrence of symptoms. Results: The mean preprocedural cyst size was 72.98 ± 25.14 mm, and the mean preprocedural cyst volume was 205.76 ± 244.15 mL. The mean volume of ethanol used in the first sclerotherapy session was 62.76 ± 30.71 mL. The mean fluid accumulation in the cysts at the end of the first 24-h interval was 4.66 ± 7.13 mL. The mean quantity of ethanol used in the second sclerotherapy session was 26.48 ± 22.2 mL. A third sclerotherapy session was required in only 10 (13.2%) of the cysts. The mean follow-up period was 52.84 ± 37.83 months. The rate of complete regression was 97.4% for the whole sample at the end of the follow-up. Conclusion: Ethanol ablation with 24-h intervals is a safe and effective treatment option in the minimally invasive percutaneous treatment of simple renal cysts.

title: High resistance levels in brazilian Plutella xylostella populations: needs for adjustments in field concentration

description: ABSTRACT Plutella xylostella cause severe damage on cruciferous plants all over the world. Farmers in several regions of Brazil report increasing inefficiency of chemical control, even when using high insecticide concentrations. We evaluate here the susceptibility of brazilian diamondback moth populations to the Premio® (Chlorantraniliprole), Dipel® (Bacillus thuringiensis var. kurstaki) and Lannate® BR (Oxime Methylcarbamate) insecticides, frequently used in Brazil. Susceptibility bioassays with five field-collected and two laboratory diamondback moth populations were conducted with increasing concentrations of insecticides up to ten times above the recommended concentration. Extremely high and region-dependent resistances were found in field populations against Chlorantraniliprole and B. thuringiensis, with Resistance Ratios up to 370.0 times for the Camocim de São Felix population. For Oxime Methylcarbamate, we were not able to do Probit analyses for the field populations because of very low mortality rates. Laboratory populations showed resistance to the three tested insecticides with all LC50 concentrations exceeding the recommended doses by at least 3 times. Our results show strong and variable resistance to the three tested insecticides according to the region of origin. To maintain efficient pest control in a large country like Brazil, local levels of resistance need therefore to be monitored by the authorities and reassessment and adjustments of regional doses of insecticides should be implemented as a public policy, to prevent massive spread of insecticides in the field, as well as increases in cases of resistance.
