title: Agronomy researchers and research scholars in Brazil: Gender, scientific age, scientific production and impact, and training of human resources

description: ABSTRACT Transparency of evaluation criteria and monitoring recommendations for research grants require careful judgment and frequent reassessment of guiding parameters. The aim of this study is to inform the scientific community and funding agencies about the applicants profile for research productivity grants (PQ) in the field of Agronomy of the National Council for Scientific and Technological Development (CNPq), and to contribute to the analysis of grant distribution using the grant applicants of the 2018 call as a study sample. The data registered in the Lattes Curriculum platform were used to quantify the scientific production index. This index considers the number of published articles with different weights for the different segments of the journal’s impact factor values, in addition to the number of patents and books, and human resources training index that considers the number of supervisions and their level (scientific initiation, master’s, doctorate and post-doctorate) completed as principal advisor. The H index (ISI-Web of Science base and Scopus base), scientific age (equal to the number of years after doctorate thesis defense), and the m index (H index divided by scientific age) were also considered, as well as the gender of the fellows. The results show that more than three quarters (75.8 %) of Agronomy PQ fellows are male. At the Category 1 levels and on the Agronomy Committee itself, the relative participation of female researchers is even lower. Women are more involved in human resource training, publish more in non-JCR journals, and are older (scientific age) at the lower level of fellow and among candidates, while men have greater scientific production, H and m indices, and m increase as scientific age advances. The indices of scientific production and human resources training, and national/international insertion (H index) are not homogeneous within the same level/category, despite the search for more transparent and verifiable evaluation indices/indicators. There are fewer opportunities for success and advancement for women, which characterizes a space for achieving gender equity. Objective, easily calculated indices/indicators are absolutely necessary for a large number of researchers, while the critical evaluation and the search for more such parameters must move forward and be compatible with the peer-review process. We suggest that CNPq collect data on citations to Google Scholar and, in particular, share information on gender and interruptions due to illness, maternity and paternity, and care for the sick, elderly or dependent.

title: Ti-LAYERED MATERIALS APPLIED IN PHOTOCATALYTIC PROCESSES

description: Titanium (Ti)-layered materials have interesting characteristics for photocatalytic applications, such as the high specific surface area and ease of intercalation of species in the interlamellar region, which are extremely favorable for the surface processes. In this sense, this review addresses the data available in the literature related to the preparation, structure and main photocatalytic applications of Ti-layered materials. The main synthesis methodologies of these materials were addressed: the hydrothermal, which is mainly used to obtain powders (containing TiO2 or titanates) and the anodization process that is commonly used to obtain films composed mainly of TiO2 nanotubes. Prominent photocatalytic applications for semiconductors were also addressed, focusing on the use of pure or associated Ti-layered materials for the photodegradation of emerging pollutants, photoreduction of CO2 or metals, hydrogen production and the inactivation of microorganisms. It was possible to observe that, despite these being extremely promising materials and with outstanding efficiency in some processes, such materials can still be considered little explored and deserve greater attention from researchers in the area.

title: Influence of shadowing in Sequoia sempervirens (D. Don) Endl. mini-stumps and mini-cuttings

description: ABSTRACT The aim of the work was to analyze the influence of variables such as shading, temperature and humidity in the production and rooting of mini-cuttings of Sequoia sempervirens (D. Dom) Endl. in a clonal mini-garden. The experiment was conducted at the Forest Nursery at the University of Santa Catarina State - CAV/UDESC, Lages - SC. The minicuttings were obtained by vegetative rescue of a single clone (A228). The original S. sempervirens individuals studied are located in the National Forest of São Francisco de Paula -RS (FLONA). Sprouts were collected 90 days after the application of girdling rescue techniques. Subsequently, mini-stumps were obtained, which were submitted to three different treatments: T1 - Mini-stumps without shading protection, T2 - Mini-stumps with single layer of shading and T3 - Mini-stumps with double layer of shading. There was no significant difference for humidity and temperature in relation to the production of mini-cuttings by the mini-stumps, while for shading the treatments T2 and T3 showed greater efficiency. It is possible that the shading treatments on S. sempervirens mini-stumps allows the vegetative tissue to be more juvenile, obtaining excellent results in cutting.

title: Effects of thymoquinone on alpha-amanitin induced hepatotoxicity in human C3A hepatocytes

description: Abstract Thymoquinone (TQ) has shown hepatoprotective effects in various experimental studies. We aimed to investigate the possible beneficial effects of TQ regarding its prevention of alpha-amanitin induced hepatotoxicity in human C3A hepatocytes. After administering alpha-amanitin in a concentrations of 1 and 10µg/mL on the cells in a hepatocyte cell line, TQ was administered in various concentrations (10, 5, 1, 0.5, 0.1, 0.05, 0.01, 0.005 µg/mL). The MTT test was used to determine cell viability. For the groups given only TQ at various concentrations, the cell viability rates at 48 hours post-administration were found at 82.6, 98.3, 102.1, 102.5, 99.4, 99.4, 101.9 and 106.3%, respectively. For the group with 1μg/mL alpha-amanitin and various TQ concentrations, the cell viability rates were found at 74.6, 88.5, 87.4, 88.7, 85.7, 86.8, 88.4, and 92.9%, respectively. For the group with 10μg/mL alpha-amanitin and various TQ concentrations, the cell viability rates for each TQ subgroup were found at 65.2, 79.2, 81.4, 81.1, 81.8, 81.8, 82.2 and 91.9%, respectively. Our study is the first in vitro study that investigates TQ’s effects on alpha-amanitin induced hepatotoxicity. Although TQ had beneficial effect in low doses did not significantly increase cell viability in liver damage due to alpha-amanitin toxicity.

title: Heritability of resistance to potato late blight in an F1 population of elite potato cultivars

description: ABSTRACT Phytophthora infestans is the most important disease in potato crops. Its control is based on the use of chemical products that have developed pathogen resistance and high economic and environmental impacts. To reduce these effects, the use of plant varieties or cultivars resistant to this pathogen has been proposed. The aim of this study was to evaluate the heritability of resistance to this pathogen in a population of elite Solanum phureja genotypes. In this study, 1,355 clones with three replicates from 20 families were included in the evaluation. Heritability was assessed in the broad and narrow senses. Results of the relative area under the disease progress curve varied between 0.08 and 0.64, indicating that the population contains genes that code for resistance. Heritability in both directions (narrow 0.022 and broad 0.255) showed significant differences, indicating an influence of dominance genetic effects and environmental effects. Thus, to use these genotypes in potato breeding programs, hybridization methods should be used instead of selection methods.

title: GUIDE FOR CHROMATOGRAPHY COUPLED TO MASS SPECTROMETRY DATA PROCESSING

description: In this work, a discussed and step-wise tutorial for LC-MS and GC-MS data processing using the open-access software MZMine2 is presented and discussed. The rationale behind each step was demonstrated to enable the readers to go through their own data and process it accordingly. The main lesson to be learned is that each parameter must be chosen in light of the raw data and no guidelines should suggest a predetermined value. Still, it is worth mentioning that ideal values for each parameter do not exist, and that the user might end up investing too much time futilely optimizing values. Our suggestion is to process your data in light of the raw data (and the study design) following the preview figure result and the resulting feature list generated in each processing step, interpret your data, and go back to process it again to tune the detection of important features.

title: Sex and slaughter weight on carcass traits and non-carcass components of horses

description: ABSTRACT: The study evaluated the effect of sex and slaughter weight on carcass traits and non-carcass components of 1,489 horses (739 geldings and 750 females, classified into eight groups according to their weight). Data were analyzed under a completely randomized design. Geldings had a higher (P &lt; 0.05) hot carcass yield (HCY) and cold carcass yield (CCY) than females; however, fat yellowness values (b*) were greater (P &lt; 0.05) in females. Slaughter weight (SW) affected the carcass characteristics. Hot carcass weight (HCW), cold carcass weight (CCW), HCY, and CCY increased (P &lt; 0.05) in accordance with slaughter weight, while cool loss percentage (CL%) was lower (P &lt; 0.05) in horses weighing more than 300 kg. In addition, the non-carcass components decreased (P &lt; 0.05) as the weight of the horses increased. In conclusion, sex and body weight are factors to consider in the production of equine meat since they affect carcass characteristics and non-carcass components.

title: Physical exercise as a therapeutic approach for adults with insomnia: systematic review and meta-analysis

description: ABSTRACT Objective To systematically review the effects (benefits and harms) of different types of physical exercise on insomnia outcomes in adult populations with no mood disorders. Objective and subjective sleep outcomes and related mismatches were analyzed. Methods Systematic review and meta-analysis. Quality of evidence was also examined. Results Six studies including 295 participants with insomnia diagnosis were selected. Yoga, Tai Chi, resistance exercise and aerobic exercise were used in protocols with different duration, intensity and frequency. Studies involved different populations, including inactive or sedentary individuals, older adults and postmenopausal women. Physical exercise improved subjective sleep quality (very low quality of evidence) and reduced insomnia severity (high quality of evidence). Conclusion Findings suggest individualized physical exercise must be addressed to design optimal protocols, with standardized type, duration, intensity, and frequency. For the time being, physical exercise may be considered an alternative and/or ancillary therapeutic modality for patients diagnosed with insomnia. Physical exercise can be used to improve subjective complaints, but not objective sleep outcomes.

title: Yield components of soybean cultivars under sowing densities

description: ABSTRACT The aim of this study was to assess yield components and grain yield of soybean cultivars in response to sowing densities. For this, two soybean cultivars and five sowing densities were tested, in a two-factor scheme. The following yield components were measured by the end of the cycle: plant height; insertion height of the first pod; number of nodes per plant; number of pods with one, two, three and four grains; number of pods per plant; number of grains per plant; weight of a thousand grains; humidity and grain yield. Sowing densities did not cause significant variations of grain yield (bags ha-1) for any cultivar, however, higher populational densities promoted a reduction in the number of pods with two and three grains, as well as a reduction in the total number of pods and grains per plant for both cultivars. Cultivar NS 5700 IPRO was the most productive, with a higher number of pods with two and three grains and number of pods and grains per plant.

title: Source-sink relationship of soybean accessed by increasing in solar radiation through the plant canopy

description: ABSTRACT The photosynthetic metabolism is a key point to improve soybean yield. In this work, we demonstrated that radiation use by soybean plants can be improved, aiming to improve the grain yield in the lower canopy. The objective of this study was to observe whether the increase in solar radiation input in the canopy of soybean plants improves their yield performance. Three experiments were carried out during the 2017/2018 season. For each experiment, treatments consisted in the opening of one or two side rows of cultivation at the R2 and R5 stage of soybean plants (NA5909RR) until maturity, plus a control. Increase on solar radiation provided by the oppening of rows enhanced the yield potential in the nodes of the lower canopy, mainly when two rows were opened. The main benefits of increasing the radiation available throughout the canopy of soybean plants are observed in the number of pods and thousand-grain weight, demonstrating the importance of increasing the availability of assimilates in lower leaves. Interestingly, the benefits of the increase in solar interceptation were observed regardless of the yield potential of the area, which varied between 4.9 and 6.7 ton ha-1.
