title: Parasitism of Tetrastichus howardi (Ollif, 1893) (Hymenoptera: Eulophidae) on Chrysodeixis includens (Walker, [1858]) (Lepidoptera: Noctuidae) pupae at different ages

description: ABSTRACT Tetrastichus howardi (Olliff, 1893) (Hymenoptera: Eulophidae) is an adult parasitoid of lepidopteran pests, and the age of the host has a strong influence on its reproduction. This study aimed to evaluate the biological characteristics of T. howardi reared on different aged pupae of Chrysodeixis includens (Walker, [1858]) (Lepidoptera: Noctuidae). For that, pupae with 24, 48, 72, 96, 120, 144 or 168 h of age were exposed to parasitism. The experimental design was completely randomized, with seven treatments (pupal age) and ten replications, with each replication consisting of five pupae individualized with one female parasitoid at the respective ages. Tetrastichus howardi parasitized and emerged in pupae of all the evaluated ages. The duration of the cycle (egg-adult) in days, number of parasitoids that emerged per pupa (progeny), progeny per female, sex ratio of the parasitoid and longevity of adults were similar. This is the first record of T. howardi reproducing in C. includens pupae under laboratory conditions. The highest parasitism and development of T. howardi was obtained in 24-to 96-hour-old pupae of C. includens, indicating that this age range is more favorable to rear this parasitoid under laboratory conditions.

title: Exposure to lipopolysaccharide and calcium silicate-based materials affects the behavior of dental pulp cells

description: Abstract This study assessed the cell viability, cytokine production, and mineralization potential of human dental pulp cells (hDPCs) after exposure to lipopolysaccharide (LPS) and application of calcium silicate-based materials (CSBM). Characterization of the CSBM was performed by infrared spectroscopy (n = 3). Extracts of Bio-C Repair, Biodentine, Cimmo HD, and MTA Repair HP were prepared and diluted (1:1, 1:4, and 1:16). Culture of hDPCs was established and treated or not with 1 µg/mL of LPS from Escherichia coli for 7 days. MTT assay was used to assess cell viability at 24, 48, and 72 h (n = 6). Alkaline phosphatase (ALP) activity was assayed on day 7 (n = 4). Il-10 and TNF-α were quantified by ELISA at 24 h (n = 6). Data were analyzed by ANOVA and Tukey’s test (α = 0.05). Cell viability of LPS-activated hPDCs was higher than untreated control in 48 and 72 h (p &lt; 0.05). Differences between non-treated and LPS-activated hPDCs were observed for Biodentine and Cimmo HP (p &lt; 0.05). The CSBM influenced the cell viability (p &lt; 0.05). ALP activity was higher in LPS-activated hDPCs (p &lt; 0.05). No changes in the concentration of TNF-α were observed between groups (p &gt; 0.05). The CSBM increased the Il-10 production (p &lt; 0.05). LPS-activated hDPCs presented increased cell viability and ALP activity. The CSBM showed mild toxicity and was able to enhance the cell viability and mineralization potential of untreated and LPS-activated hDPCs. The CSBM also induced anti-inflammatory mechanisms without compromising pro-inflammatory ones.

title: Inoculation and co-inoculation with multifunctional rhizobacteria for the initial development of soybean

description: ABSTRACT Soybean inoculation and co-inoculation with multifunctional rhizobacteria is a sustainable alternative that may contribute to plant growth and increased agricultural production, making the product more competitive, as well as reducing costs for the producer. This study aimed to evaluate the effect of inoculation and co-inoculation with multifunctional Serratia sp. and Bacillus sp. rhizobacteria on the early development of soybean. A completely randomized experimental design was used, with four treatments and ten replicates, totaling 40 experimental plots. The treatments consisted of the microbiolization of soybean seeds and a control treatment: BRM 32114 (Serratia sp.) isolate; BRM 63573 (Bacillus sp.) isolate (formerly named 1301); co-inoculation with BRM 32114 + BRM 63573; and control (without microbiolization). BRM 32114 and BRM 63753, both isolated and combined, were eficient to improve the initial development of soybean seedlings, providing significant effects for most of the analyzed variables (length, total surface, root volume and root, shoot and total biomass), when compared to the control treatment.

title: An investigative study on teachers' level of expertise on the triad science-pedagogy-technology: evaluating Chemistry classrooms during the pandemic

description: Abstract: During the pandemic, the required changeover to Emergency Remote Teaching presented various technological hurdles for instructors all around the world, as well as a fertile field of study dedicated to reshaping existing teaching methods into the manner in which education is delivered today. With an investigative slant, this study examines a group of students' perceptions on their professors' pedagogical practices, focusing on abilities and competencies related to Technological Pedagogical Content Knowledge (TPACK). To that purpose, 324 students evaluated their professors' ability to grasp the interrelated triangle of scientific, pedagogical, and technical material in their lessons. The Survey research technique was employed for a quantitative inquiry, then a statistical method of deductive imprint. When combined with the pedagogical aims and scientific contents of chemical science, the findings indicate a guiding need for teaching techniques and pedagogical reform for the development of technological skills.

title: Control of barnyardgrass susceptible and resistant to imidazolinones at different temperature regimes before and after imazethapyr application

description: ABSTRACT Environmental conditions can influence herbicide metabolism and interfere with the evolution of weed resistance. This study aimed to evaluate the effect of thermal regimes on the control of barnyardgrass (Echinochloa crus-galli) susceptible and resistant to herbicides of the imidazolinones chemical group. Factor A (biotypes) consisted of one biotype that is susceptible and one that is resistant to imazethapyr; factor B (dose) comprised six imazethapyr doses between 0 and 800 g ha-1 for the resistant biotype and between 0 and 100 g ha-1 for the susceptible biotype; factor C (temperature) consisted of four thermal regimes (16/16 ºC, 25/25 ºC, 16/25 ºC and 25/16 ºC) to which the plants were submitted before and after the herbicide application. Concerning the resistant biotype, the highest control levels were observed in the thermal regimes with temperature fuctuation, especially at 25/16 ºC. At the recommended imazethapyr dose (100 g ha-1), the herbicide resulted in a control level over 90 % at 25/16 ºC and less than 50 % at 16/16 ºC, in the resistant biotype. The shoot dry mass was reduced by more than 80 % at 25/16 ºC and 16/25 ºC and less than 30 % at 16/16 ºC. The temperature conditions to which the plants are subjected in the pre- and post-application period interfere with the level of imazethapyr resistance in barnyardgrass.

title: The role of the artificial ponds for the conservation of mammals in the state of Santa Catarina

description: Abstract Man has profoundly modified the upper valley of the Uruguay River and its basin. The plains of these valleys and the lower areas of the hills have been modified for agricultural production, leaving small patches of wild forest on the tops of the hills, where wildlife takes refuge. These less modified sectors generally lack water. Therefore, the wild mammals must descend to the bottom of the valleys to drink. However, there are numerous fence lines between the hills and the rivers and streams which prevent the fauna access to these watercourses, so they ingest water from artificial ponds present in the agricultural establishments instead, which is reflected in the high values of δ18O observed in the bone bioapatite of local wild mammals. This finding highlights the importance of artificial reservoirs distributed in the agricultural landscape of Santa Catarina for the preservation of wildlife and the importance of their sanitary monitoring to prevent the transmission of diseases from livestock to wildlife.

title: Functional analysis of alternative castor bean DGAT enzymes

description: Abstract The diversity of diacylglycerol acyltransferases (DGATs) indicates alternative roles for these enzymes in plant metabolism besides triacylglycerol (TAG) biosynthesis. In this work, we functionally characterized castor bean (Ricinus communis L.) DGATs assessing their subcellular localization, expression in seeds, capacity to restore triacylglycerol (TAG) biosynthesis in mutant yeast and evaluating whether they provide tolerance over free fatty acids (FFA) in sensitive yeast. RcDGAT3 displayed a distinct subcellular localization, located in vesicles outside the endoplasmic reticulum (ER) in most leaf epidermal cells. This enzyme was unable to restore TAG biosynthesis in mutant yeast; however, it was able to outperform other DGATs providing higher tolerance over FFA. RcDAcTA subcellular localization was associated with the ER membranes, resembling RcDGAT1 and RcDGAT2, but it failed to rescue the long-chain TAG biosynthesis in mutant yeast, even with fatty acid supplementation. Besides TAG biosynthesis, our results suggest that RcDGAT3 might have alternative functions and roles in lipid metabolism.

title: Reinoculation of topdressing Rhizobium tropici combined or not with Azospirillum brasilense in common bean

description: ABSTRACT The nitrogen (N) supplying capacity of common bean plants through biological fixation is still questioned by farmers. This study aimed to investigate the nodulation, growth and production of common bean cultivars under field conditions, when subjected to topdressing Rhizobium tropici reinoculation applied at different rates, combined or not with Azospirillum brasilense. A randomized blocks design was used, in a 2 × 4 × 2 + 2 factorial arrangement, with four replications. The treatments consisted of two common bean cultivars (BRS-Estilo and BRS-Esteio) reinoculated with four R. tropici rates (0-, 1-, 2- and 4-fold the reference rate), combined or not with A. brasilense in co-inoculation. The additional treatments consisted of nitrogen fertilizer applications (20 and 50 kg ha-1 at planting and as topdressing, respectively) for both cultivars. The variables evaluated at the R6 stage were nodulation (number of active nodules and nodule dry weight) and morphological plant characteristics (root length and dry weight, plant height, shoot dry weight and N content), while, at harvest, the number of pods per plant, number of grains per pod, 100-grain average weight and grain yield were evaluated. The topdressing reinoculation of R. tropici combined with A. brasilense at the V4 stage affected the nodulation process and agronomic characteristics of the common bean plants. When performed in addition to seed inoculation, it may totally replace the supply of mineral N in the crop, allowing the achievement of high yield levels.
