ABSTRACT Currently with a more demanding market, is necessary to produce better and high physiological quality cultivars of soybeans. In front of this new challenge, our objective was to evaluate the physiological quality of 11 soybean cultivars: CD201, SYN1263, SYN1279, BMX, UFLA1, CA115, CD215, CD202, Conquista, Savana, and BRS820 storage for 12 months. Evaluations were conducted through physiological like germination and vigor (accelerated aging and controlled deterioration) and isoenzymes analysis. The seeds were stored under controlled conditions at 10 °C and 10% relative humidity. It was assessed every four months (0, 4, 8, and 12). 200 seeds per treatment were used for each test, divided into 4 replications of 50 seeds. The number of normal plants was evaluated on the fifth and seventh days, expressed as a percentage value. Isoenzyme analysis of MDH, ADH, Esterase, and Catalase was made.

Microparticulated whey protein can be used as a fat substitute in foods to enhance their nutritional value and improve their sensory and rheological characteristics. Microparticulation denatures whey proteins through heat treatment, followed by shear rate control to determine the aggregate sizes formed. The processing method used during microparticulation can modify the protein denaturation rate, which may enable the application of new proteins. This study sought to develop a methodology for quantifying whey protein fractions in commercial samples before and after microparticulation at different concentrations and physical states. The developed methodology proved to be applicable because of its selectivity, quantification, detection limits, and precision. The analyzed samples exhibited a higher denaturation rate for β-lactoglobulin than α-lactoalbumin; the denaturation rate varied among samples due to differences in the microparticulation process. characteristics treatment formed states selectivity quantification limits precision βlactoglobulin β lactoglobulin αlactoalbumin α lactoalbumin α-lactoalbumin process

This work aimed to incorporate the active compounds of the jambolan leaf in sunflower seed oil, in order to increase the nutritional quality of the oil. For this purpose, ultrasound-assisted extraction was conducted to establish the process conditions related to temperature, potency, solvent:sample ratio and time to obtain the enriched sunflower seed oil (ESSO). An experimental design was applied to examine the effect of variables (temperature, power, solvent:sample ratio and time) on the extraction mass yield (EMY). The application of maximum temperature, increased power, sample:solvent ratio and time resulted in higher EMY. Maximum theoretical EMY value was 35.16% (60 °C, 100%, 1:12 g mL-1 and 15 min). The characterization of the oils obtained from ESSO and sunflower seed oil (SSO) verified a higher content of flavonoids, phenolic compounds, a large proportion of active compounds, antioxidant activity, content of phytosterols, α-tocopherol and squalene, and induction time for ESSO. purpose ultrasoundassisted ultrasound assisted temperature potency solventsample solvent sample .

Bisphenol A (BPA), an endocrine disruptor used in different commercial polymers, is a persistent pollutant commonly found in effluents. Conventional wastewater treatment processes have low chemical removal efficiency and are expensive. This work evaluated BPA removal using laccase enzyme produced from white rot fungus Pleurotus ostreatus. For the enzymatic production, residues of acai berry and pineapple were used as laccase inducers. The use of natural inducers led to a high enzyme production (1139 and 1031 U mL−1 to acai and pineapple, respectively). Bisphenol A was removed to a concentration lower than LOD (limit of detection) after 4 h. The degradation mechanism of BPA occurred by oxidation of methyl to hydroxymethyl group in a propane portion, with breakdown of the aromatic ring. The developed technology brought to the scene a new green, viable methodology, using vegetable waste, adding value to these residues and bringing an alternative to the BPA treatment.

The present work focused on the screening process of different inorganic oxides and different temperatures for the epoxidation reaction of macaw palm vegetable oil without using solvent, a promising Brazilian biomass that can substitute other vegetable oils (e.g., soybean oil) in technological applications. This oil has an iodine value of 108.48 g of I2 per 100 g being categorized as a semi-dry oil. The epoxidized vegetable oil can be applied in manifold areas in polymer science. The epoxidation reaction here presented avoided organic solvents and organic acids and aimed to produce a greener route using metal oxides or niobium phosphate as a peroxide-activating catalyst. The experimental parameters were maintained as 10 mol% of catalyst loading and a time of 24 h; however, the temperature for some catalysts was changed to improve the epoxide conversion. Experiments were measured by proton nuclear magnetic resonance (1H NMR). Experiments using titanium oxide (TiO2) as a catalyst reached a conversion greater than 84.7%, while experiments using aluminium oxide (Al2O3) or lanthanum oxide (La2O3) achieved conversions of 22.6 and 30.1%, respectively. Furthermore, it was observed that both niobium compounds instantly react with hydrogen peroxide to form peroxy derivatives. solvent e.g., eg e (e.g. applications 10848 108 48 108.4 I semidry semi dry science peroxideactivating activating 1 mol 2 h however 1H H NMR.

High-density polyethylene (HDPE) geomembranes are commonly used as an environmental protection liner due to their good chemical and mechanical resistances and low cost. Ultraviolet (UV) radiation is an essential issue in durability studies for pond applications. This study evaluated a 1.5-mm thick HDPE geomembrane exposed to ultraviolet fluorescent radiation for 8760 h in a laboratory and thermoanalytical and physical analyses were conducted towards the understanding of its performance after exposure. According to the results, although the geomembrane maintained the ductile behavior, it showed a 52.48% final decrease in stress crack resistance (SCR) compared to virgin SCR. Moreover, a considerable antioxidant depletion occurred after 8760 h exposure shown by the Std. OIT (standard oxidative-induction time) results, demonstrating a Std. OIT value decrease of 89.19% compared to the virgin Std. OIT. Such a behavior contributed to the susceptibility of thermal effects in the DSC (differential scanning calorimetry) curves and the losses observed in the SCR values, attesting the geomembrane’s oxidative degradation mechanism occurred and changed the polymer’s structure.

The recycle and utilization of expired drugs is a challenge for many countries at present. The employment of expired drugs as green corrosion inhibitors is expected to address both drug recycling and corrosion prevention issues, with significant economic and environmental value. Herein, the individually and combination corrosion inhibition performance of expired amoxicillin (AMC) and penicillin V potassium tablets (PVP) for lowcarbon steel in 20% acetic acid solution containing 600 mg L-1 chloride ion are evaluated by electrochemistry and weight loss method. Both the AMC and PVP present the mixed-type corrosion inhibitors mainly affect the cathode process when used individually. The optimum inhibition efficiency is 61.22% (AMC) and 79.21% (PVP), which all appear in 5.0 × 10-3 mol L-1. The AMC and PVP are adsorbed on the steel surface by mixed physisorption and chemisorption, which are consistent with the Langmuir adsorption isotherm. The corrosion inhibition rate drops sharply when AMC and PVP are combined use with a close mole ratio. But a small amount of PVP significantly enhance the corrosion inhibition effect of AMC, the corrosion inhibition rate from 61.22 to 79.72%. The corrosion inhibition rate of AMC and PVP combination inhibitor decreased with the increase of temperature. issues value Herein (AMC (PVP 20 60 L1 L 1 L- method mixedtype type 6122 61 22 7921 79 21 79.21 PVP, , 50 5 0 5. 103 10 3 10- L1. 1. chemisorption isotherm ratio 61.2 7972 72 79.72% temperature 2 6 612 792 7 79.2 61. 797 79.72 79. 79.7

ABSTRACT Purpose: This study aimed to compare the safety and effectiveness of intraocular pressure reduction between micropulse transscleral cyclophotocoagulation and “slow cook” transscleral cyclophotocoagulation in patients with refractory primary open-angle glaucoma. Methods: We included patients with primary open angle glaucoma with at least 12 months of follow-up. We collected and analyzed data on the preoperative characteristics and postoperative outcomes. The primary outcomes were a reduction of ≥20% of the baseline value (criterion A) and/or intraocular pressure between 6 and 21 mmHg (criterion B). Results: We included 128 eyes with primary open-angle glaucoma. The preoperative mean intraocular pressure was 25.53 ± 6.40 and 35.02 ± 12.57 mmHg in the micropulse- and “slow cook” transscleral cyclophotocoagulation groups, respectively (p<0.001). The mean intraocular pressure was reduced significantly to 14.33 ± 3.40 and 15.37 ± 5.85 mmHg in the micropulse- and “slow cook” transscleral cyclophotocoagulation groups at the last follow-up, respectively (p=0.110). The mean intraocular pressure reduction at 12 months was 11.20 ± 11.46 and 19.65 ± 13.22 mmHg in the micropulse- and “slow cook” transscleral cyclophotocoagulation groups, respectively (p<0.001). The median preoperative logMAR visual acuity was 0.52 ± 0.69 and 1.75 ± 1.04 in the micropulse- and “slow cook” transscleral cyclophotocoagulation groups, respectively (p<0.001). The mean visual acuity variation was −0.10 ± 0.35 and −0.074 ± 0.16 in the micropulse- and “slow cook” transscleral cyclophotocoagulation, respectively (p=0.510). Preoperatively, the mean eye drops were 3.44 ± 1.38 and 2.89 ± 0.68 drugs in the micropulse- and “slow cook” transscleral cyclophotocoagulation groups, respectively (p=0.017), but those were 2.06 ± 1.42 and 1.02 ± 1.46 at the end of the study in the “slow cook” and micropulse transscleral cyclophotocoagulation groups, respectively (p<0.001). The success of criterion A was not significant between both groups. Compared with 11 eyes (17.74%) in the “slow cook” transscleral cyclophotocoagulation group, 19 eyes (28.78%) in the micropulse transscleral cyclophotocoagulation group showed complete success (p=0.171). For criterion B, 28 (42.42%) and 2 eyes (3.22%) showed complete success after micropulse- and “slow cook” transscleral cyclophotocoagulation, respectively (p<0.001).

The acetalization or transacetalization reactions produce acetals or ketals used in cosmetics, food, pharmaceuticals, and fuel additives. Besides synthesizing several products, the acetalization or transacetalization reactions can protect carbonyl groups, 1,2 and 1,3-diols in multi-step synthesis. This work studies the transacetalization of glycerol with 2,2-dimethoxypropane (2,2-DMP) to yield 2,2-dimethyl-4-hydroxymethyl-1,3-dioxolane (solketal) by catalyzing with USY, HBeta, and HZSM-5 zeolites under cleaner and mild reaction conditions (reaction temperature: 25 °C; 2,2-DMP/glycerol molar ratio: 1; reaction time: 1 h; and catalyst concentration: 0.05-5 wt.%). For catalyst concentration equal to or greater than 2,5 wt.%, glycerol conversion stabilized near 96-97% for the three zeolites tested. The product selectivities also assume a constant value, close to 97% for solketal. For the lowest concentration of catalyst, the influence of the zeolite properties on the glycerol conversion, such as acidity and the strong/weak acid site ratio, was observed. Concerning the selectivity of the products, the results suggested that it can be based on zeolite topology, active sites at the particle surface, and the relative amount of micro and mesoporous HBeta, the most selective catalyst for acetals production, was reused at least once without loss of activity and selectivity. cosmetics food pharmaceuticals additives products groups 12 2 1, 1,3diols 13diols diols 1,3 3 multistep multi step synthesis 2,2dimethoxypropane 22dimethoxypropane dimethoxypropane 2,2 2,2DMP 22DMP DMP (2,2-DMP 2,2dimethyl4hydroxymethyl1,3dioxolane 22dimethyl4hydroxymethyl13dioxolane dimethylhydroxymethyldioxolane dimethyl 4 hydroxymethyl dioxolane solketal (solketal USY HBeta HZSM5 HZSM 5 HZSM- temperature °C C 2,2DMP/glycerol 22DMPglycerol DMPglycerol DMP/glycerol ratio time h 0.055 0055 0.05 0 05 0.05- wt.%. wt wt.% . wt.%) 2, 9697% 9697 96 97 96-97 tested value strongweak strong weak observed topology surface production 3diols 13 2dimethoxypropane 22 2DMP 2dimethyl4hydroxymethyl1 3dioxolane 055 005 0.0 wt. 969 9 96-9 dimethylhydroxymethyl 2dimethyl4hydroxymethyl 00 0. 96-

In the present study a spectrophotometric method for Cr(VI) determination in organic fertilizers, especially those from tanning industry residues, is proposed. Conditions for chromium extraction, extract clean-up and analytical characteristics of the method were established. The method is based on the complexation of Cr(VI) with 1,5-diphenylcarbazide (DPC) in acid medium (pH 2.0). A mixture of NaOH and Na2CO3 solution at 0.125 and 0.07 mol L–1 (pH 12), respectively, and heating at 90 °C for 60 min were the best conditions for chromium extraction. Florisil and activated charcoal were tested for clean-up of the extract, with activated charcoal being effective. Under the established conditions, the calibration linear range is up to 2500 μg L–1 Cr(VI), the results obtained are in agreement with the value of a certified reference material (CRM041), precision is better than 5% for five consecutive determinations of a solution at 1000 μg L–1 of Cr(VI) and the limit of quantification is 1.62 μg g–1. In can be concluded that the method is robust, accurate and precise, and can be easily applied for the determination of Cr(VI) in routine analysis, since it complies with legislation of most countries regarding the maximum allowed concentration of 2 μg g–1 of Cr(VI).

To control vehicle emissions, the new homologation process must be reported according to the California Maximum Incremental Reactivity (MIR) scale’s procedure to calculate the ozone forming potential (OFP) of each new vehicle. This work calculates an MIR scale suitable for the Brazilian reality. Meteorological and hourly pollutant data from the Bangu Automatic Air Quality Station was inventoried and processed from March to September 2020 to adjust OZIPR Lagrangean model and obtain the MIR scale by making small increments in the concentrations of each volatile organic compounds (VOC) and calculate the ozone increase/decrease. It was found that the VOC that had the greatest impact on ozone formation was 1,2,4-trimethylbenzene, with 2.06 ppb O3 ppbC-1 VOC. The OFP was calculated based on the VOC emissions of a vehicle and it was found a value of 9.421 mg O3 km-1, a much lower value when compared using the California MIR scale of 136.608 mg O3 km-1. It is concluded that meteorological conditions and VOC speciation data in the air mixture in the studied region directly affect the photochemical reactions of ozone formation.

ABSTRACT: Tomatoes (Solanum lycopersicum L.) are nutrient-rich fruits with a high glutamic acid content, making them a suitable source for producing γ-aminobutyric acid (GABA) through the action of lactic acid bacteria (LAB). LAB plays a pivotal role in lactic fermentation, enhancing the taste and nutritional value of food products, often contributing to their health benefits. This study isolated GABA-producing LAB from tomatoes and assessed their potential for producing GABA-enriched fermented tomato juice. The results indicated the isolation of 15 LAB strains from the samples of five different tomatoes. All of these strains demonstrated the capability to produce GABA, with levels ranging from 1.732 to 3.113 mg/mL, as determined using thin-layer chromatography (TLC). Through sequencing, the promising strain TO42, identified as Weissella cibaria, was selected for tomato juice fermentation. Furthermore, GABA-enriched tomato juice was successfully fermented at 15 °Brix for 72 h, resulting in the highest recorded GABA and lactic acid content of 9.185 ± 0.398 mg/mL and 13.05 ± 1.56 g/L, respectively.

Computational predictive approaches present themselves as an attractive alternative in the search for new compounds that may present toxic or growth regulatory activity in Aedes aegypti. Aspergillus species is a producer of secondary metabolites with diverse biological activities. In this study, it was possible to evaluate the pharmacokinetic and toxicological properties in silico, as well as the prediction of the insecticidal biological activities of the juvenile hormone of natural substances produced by the genus Aspergillus. Initially, 187 molecules were cataloged from various species of Aspergillus spp., and only seven molecules of indole alkaloids were found to exhibit a toxic dose 50% (TD50) after conducting toxicity predictions. The molecular dynamic simulation trajectories were utilized to study parameters such as root mean square deviation, root mean square fluctuation, radius of gyration and intermolecular hydrogen bond to understand the behavior and stability of proposed compounds in the binding pocket of the target protein. The N-β-acetyltryptamine molecule showed a binding affinity value of –8.100 ± 0.200 kcal mol-1, which classifies the compound as a potential insecticidal agent against the Aedes aegypti vector. silico Initially 18 spp spp. 50 TD50 TD (TD50 predictions deviation fluctuation protein Nβacetyltryptamine N β acetyltryptamine 8100 8 100 –8.10 0200 0 200 0.20 mol1, mol1 mol 1, 1 mol-1 vector 5 TD5 (TD5 810 10 –8.1 020 20 0.2 mol- (TD 81 –8. 02 2 0. –8 –

Abstract: This article aims to analyze changes in the residential and commercial dynamics of a neighborhood in the south of Belo Horizonte. Using the Urban Property and Territorial Property Tax register and the Real Estate Transfer Tax register, it was possible, not only to identify and map the new residential and commercial properties built in the neighborhood in the last decade, but to outline the profile of its new residents and consumers. The concept of gentrification is taken into account as a process of replacing a social class with a lower status by another with a higher status, to examine the results found. The data point to a process of physical change, marked by the greater supply of buildings with a high standard of finishing and high value, aimed at a social group with a higher status than the previous residents. The main actor behind these changes is the real estate market. Abstract Horizonte possible decade consumers found change value market
