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.

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 Amazon, Euterpe oleracea Mart. (açaí), is part of the identity of traditional communities, and the fruit is integrated into their everyday sociocultural dynamics. Hydrolysis and pyrolysis of residual biomass can be alternatives to yield sugars, ethanol, biochar and bio-oil. The açaí seeds subjected to oxidative pretreatment followed by acid hydrolysis increased cellulose to fermentable sugars (reaching 23.5%) and second-generation ethanol production (17.441 L t−1). Açaí oil (ca. 30%) was extracted using a Soxhlet apparatus (using hexane as solvent) and detected through gas chromatography coupled to mass spectrometry (GC-MS), where acids accounted for 82.43% of the total composition, while alcohols comprised only 13.15%. For pyrolysis, temperatures (500 and 550 °C), time (20 and 30 min), and activation temperature (750 and 800 °C) were evaluated, resulting in yields of ca. 22% for biochar and 30% for bio-oil. For the bio-oil, the main compounds detected by GC-MS were acids (16.3%), aldehydes (13.08%), amides (12.19%), alcohols (6.72%), and phenols (4.64%). The obtained biochar displayed surface area values of 553.7 m2 g−1 and 10% crystallinity, indicating its more amorphous nature.

The selective separation of precious metals from complex aqueous solutions is important in protecting the environment, aquatic ecosystems, water resources and recycling resources. In this study, cysteine-containing polymeric nanoparticles were synthesized using the molecular imprinting (MIP) technique with the mini-emulsion polymerization method. The basis of the polymer design is inspired by affinity of silver to cysteine in biological systems. The synthesized silver ion imprinted (Ag+-IIP) poly(hydroxyethylmethacrylate-N -methacryloyl-L-cysteine) poly(HEMA-MAC) nanoparticles were characterized by elemental analysis, zeta sizer, Fourier transform infrared (FTIR) spectroscopy, atomic force microscopy (AFM), and scanning electron microscopy (SEM). The effects of pH, ionic strength and interaction time on adsorption of Ag+ ions were investigated. In experimental studies, the highest adsorption amount (196.9 mg g1 nanoparticle) was reached in a short period of 40 min at pH 5.0 and 150 mg L-1 concentration. Selectivity studies of synthesized Ag+-IIP nanoparticles against silver (Ag+) ions were carried out in the presence of lithium (Li+), barium (Ba2+), mercury (Hg2+) and cadmium (Cd2+) ions. Experimental results indicate that nanoparticles adsorb Ag+ ions with high selectivity. Ag+-IIP nanoparticles have 3.7, 3.1, 2.4, and 2.6 times more selective or higher affinity for Ag+ ions compared to Li+, Ba2+, Hg2+ and Cd2+ ions, respectively, compared to Ag+-non-imprinted (NIP) nanoparticles. environment ecosystems study cysteinecontaining containing MIP (MIP miniemulsion mini emulsion method systems Ag+IIP AgIIP IIP Ag (Ag+-IIP polyhydroxyethylmethacrylateN poly hydroxyethylmethacrylate N methacryloylLcysteine methacryloyl L -methacryloyl-L-cysteine polyHEMAMAC HEMA MAC poly(HEMA-MAC analysis sizer FTIR (FTIR spectroscopy AFM, AFM , (AFM) SEM.

Layered double hydroxides (LDHs) and related materials have been studied for a long time and their application in catalytic processes remain attractive due to the tuned properties, morphologies and metal-support interactions obtained from a variety of composition and synthesis route. In this mini-review, some important reactions, such as photocatalysis, electrocatalysis, reduction, carbon-carbon cross-couplings and water-gas shift will be emphasized along with the role of LDHs as catalysts, co-catalysts or catalytic precursors when it was clearly indicated.

Gold and platinum bimetallic nanoparticles, Au@PtNPs, have gained attention due to their plasmonic properties. The controlled synthesis of Au@PtNPs involves complex parameters, and the resulting synergy between Au and Pt introduces possibilities for tailoring their properties. This study explores the effects of key-parameters of synthesis (gold core diameters, reaction time, and Pt concentration) on the final properties of Au@PtNPs. Gold nanoparticles of varying diameters were synthesized and used as cores for the reduction of hexachloroplatinic acid, forming a surrounding shell of Pt nanoparticles. The parameters were systematically tuned to understand their impact on morphology, dimension, stability, and plasmonic properties of Au@PtNPs. Increasing Pt precursor concentration resulted in thicker and denser Pt shells, broadening the localized surface plasmon resonance (LSPR) band and improving Au@PtNPs stability. These properties are essential for applications such as photothermal treatment. The synthesis achieved satisfactory products within just 1 h of Pt4+ reduction at mild temperature without using surfactants. Only limited changes in plasmonic properties were observed after 4 h of synthesis, suggesting an optimal reaction period. Manipulating Au core diameter provided LSPR band control, with smaller cores exhibiting greater broadening towards the infrared region. This systematic exploration provided valuable insights for understanding key-parameters governing the synthesis and properties of Au@PtNPs.

Parthenolide (PTN) is a secondary metabolite of the plant Tanacetum parthenium (L.) Schulz Bip. and is considered the chemical marker of this species. This sesquiterpene lactone (germacrene skeleton) has been described as responsible for the biological activity of the leaf extract. In addition, several studies in the literature have demonstrated its antiparasitic and antineoplastic activity. However, there is a need for knowledge of other safety parameters, such as pharmacokinetic, pharmacodynamic and toxicity evaluations. Therefore, in this investigation, the in vitro metabolism of parthenolide was performed with rat liver microsomes and biomimetic metabolism (such as cytochrome P-450 system) using organometallic catalysts. The biomimetic procedure was validated since the major compound of biomimetic oxidative reaction with meta-chloroperbenzoic acid catalyzed by metalloporphyrin 5,10,15,20-tetrakis(pentafluorophenyl)-porphyrin iron(III) chloride was also observed with rat liver microsomes. Previous chemoenzymatic synthesis studies of PTN afforded the same epoxide formation, this major oxidative compound was isolated and fully characterized as (1 R,10R)-epoxyparthenolide based on experimental and theoretical calculations of infrared (IR) and vibrational circular dichroism (VCD) data at the B3PW91/6-311G. Furthermore, for the first time, this metabolite was evaluated for trypanocidal and leishmanicidal activity. The mean inhibitory concentration (IC50) values were lower for PTN than its metabolite and showed significant cytotoxic effects for both parasites. This finding holds promise for addressing neglected diseases. (PTN L. L (L.

In the water/triethanolamine/ethanol system, TiCl4 aqueous solution is used as the precursor to regulate the conversion rate of TiCl4 by changing the reaction temperature, water volume, pH value, and ethanol amount. The experiment uses a single-factor method to investigate the dynamic relationship between Ti4+ concentration and time under various factors, thereby achieving controllable TiO2 production. The experimental results showed that under a single factor, the conversion rate showed a trend of first steep and then slow growth within 180 min. After 180 min, the conversion rate tended to stabilize. Considering various factors, it was found that VTiCl4:VC6H15NO3:VH2O:VC2H5OH = 1:6:15:30, pH = 7, reaction time at room temperature was 4 h, and the hydrolysis effect was good. The final conversion rate was 90.46%, and the hydrolysis reaction conforms to the first-order reaction equation.

RESUMO: O objetivo deste trabalho foi extrair lignina de Eucalyptus sp. licor negro kraft e avaliar a influência de sua adição nas propriedades do adesivo lignina-fenol-formaldeído. Os adesivos foram sintetizados em diferentes porcentagens de massa de fenol por lignina, denominados adesivos lignina-fenol-formaldeído nas proporções de 25, 30, 50, 75 e 80%. Os parâmetros avaliados nos adesivos foram pH, teor de sólidos totais, teor de compostos orgânicos, teor de compostos inorgânicos, tempo de gelatinização e comportamento do adesivo na linha de cola. O pH variou de 10,63 a 11,65. Para o teor de sólidos totais foi encontrado o valor de 53 a 69%. Os teores de compostos orgânicos variaram de 51 a 75% e de inorgânicos de 25 a 49%. Observou-se que com a adição da macromolécula na formulação do adesivo, o teor de sólidos totais e orgânicos foi reduzido proporcionalmente enquanto o de sólidos inorgânicos foi elevado. O tempo de gelatinização foi reduzido devido à adição de lignina. As menores proporções de adição apresentaram melhor penetração e fluidez na interface com a madeira. A lignina kraft extraída do licor negro kraft de eucalipto é um ótimo adesivo com potencial para substituir parcialmente o fenol derivado do petróleo, com grande potencial para uso e aplicação nos setores aeronáutico e automotivo, no processo de colagem de peças estruturais.

ABSTRACT: The objective of this research was to extract lignin from Eucalyptus sp. kraft black liquor and to evaluate the influence of its addition on the properties of the lignin-phenol-formaldehyde adhesive. The adhesives were synthesized at different phenol mass percentages by lignin, called lignin-phenol-formaldehyde adhesives in the proportions of 25, 30, 50, 75 and 80%. The parameters evaluated in the adhesives were pH, total solid content, organic compound content, inorganic compound content, gelatinization time and adhesive behavior in the glue line. The pH ranged from 10.63 to 11.65. For the total solid content was found the value of 53 to 69 %. The contents of organic compounds ranged from 51 to 75% and inorganic from 25 to 49%. It was observed that with the addition of macromolecule in the adhesive formulation, the total and organic solid content was reduced proportionally while the inorganic solid was high. The gelatinization time was reduced due to the addition of lignin. The lower proportions of addition presented better penetration and fluidity in interface with the wood. The kraft lignin extracted from eucalyptus kraft black liquor is a great adhesive with potential to partially replace petroleum-derived phenol, with great potential for use and application in the aeronautical and automotive sectors, in the bonding process of structural parts.

Considering the cytotoxic properties of Schiff base ligands, we re-synthesized a gold(III) complex with a tetradentate Schiff base ligand and investigated its cytotoxic effects using the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) method and sulforhodamine B staining method. The results showed that the gold(III) Schiff base complex can inhibit the growth of Chinese hamster ovary (CHO) cancer cell lines. However, unlike cisplatin, it does not induce cell death in NIH 3T3 normal cells. Real-time polymerase chain reaction (PCR) results revealed that the gold(III) Schiff base complex increased the Bak1/Bclx ratio in CHO cell line by 3.53-fold compared to the control, while cisplatin increased the anti-apoptotic Bclx gene by 31.8 times and the treatment resistance AKT1 gene by 430.8 times the control. However, cisplatin only activated the extrinsic pathway of apoptosis through the caspase-3 gene. The expression levels of TLR6 and TNF-α genes in normal cells showed that both the gold(III) Schiff base complex and cisplatin did not cause inflammation in NIH 3T3 cell lines. All the results indicate that the new complex could be a promising candidate to replace cisplatin. It has been shown that it induces apoptosis and prevents the development of resistance in cancer cells. Additionally, it does not cause inflammation in normal cells. ligands resynthesized re synthesized goldIII gold III gold(III 34,5dimethylthiazol2yl2,5diphenyltetrazolium 345dimethylthiazol2yl25diphenyltetrazolium dimethylthiazolyldiphenyltetrazolium 3 4,5 dimethylthiazol 2 yl 2,5 diphenyltetrazolium 4 5 bromide (CHO lines However T 3T Realtime Real time PCR (PCR Bak1Bclx BakBclx Bak1 Bak 3.53fold 353fold fold 3.53 53 control antiapoptotic anti apoptotic 318 31 8 31.

This study expands and shows the versatility of applications in hydrophilic interaction chromatography coupled with triple quadrupole mass spectrometry (HILIC-MS/MS) using a FRULIC-N column to determine 31 phenolic compounds in beverage industry residues (coffee, apple juice, beer, and wine). Optimization, via Doehlert design, determined the acetonitrile proportion (50-90%) and pH (3.0-7.0) in the mobile phase (MP). A 22 factorial design assessed the concentration of ammonium acetate (10-110 mmol L-1) in the MP and column temperature (20-60 °C). Injection volume (5-45 µL) was univariately optimized. Separations at 60 °C reduced chromatographic run time to less than 11 min. Gradient elution (500 µL min-1) employed an MP comprising acetonitrile and ammonium acetate (110 mmol L-1, pH 7). Validation demonstrated average coefficient of determination (R2) 0.9707, limit of detection 0.001-0.503 mg L-1 and quantification 0.004-1.524 mg L-1, precision < 12.2%, recovery 92.4-110.8%. The method was applied to five residues, indicating its viability for determining phenolics in beverage production residues.

ABSTRACT Objective: The aim of this study was to investigate the contextual factors associated with the quality of life (QOL) of Brazilian children aged 0–12 years during the strict period of social isolation. Methods: This observational cross-sectional study was conducted between July and September 2020 using an online questionnaire on QOL-related family factors and the Pediatric Quality of Life Inventory (PedsQL™). Results were analyzed by multinomial logistic regression analysis. Results: The sample had 849 children, mostly from the South Region of Brazil (75%), white (83%), with typical development (79%), sedentary (68%), using screen (85%) for >3 h/day (44%). Their mothers were their main caregivers (90%). The following variables were significantly associated with high scores of QOL: typical health status (OR 2.38; 95%CI 1.60–3.55; screen time ≤2 h/day (OR 1.62; 95%CI 1.17–2.24); social distancing considered as “easy” (OR 1.67; 95%CI 1.20–2.32), and stimulation of the child by the family (OR 1.93; 95%CI 1.08–3.45). Conclusions: This study indicates that the family context can influence children’s QOL, especially during the COVID-19 pandemic and home environment reorganization.

RESUMO Objetivo: Investigar os fatores contextuais associados à qualidade de vida (QV) de crianças brasileiras de zero a 12 anos, em momento de ápice de distanciamento social. Métodos: Estudo observacional, transversal, online, de julho a setembro de 2020, com questionário sobre fatores do contexto familiar associados à QV e Inventário Pediátrico sobre QV — PedsQL™. A análise dos dados foi feita por de regressão logística multinomial. Resultados: A amostra foi de 849 crianças, na maioria da Região Sul (75%), brancas (83%), com desenvolvimento típico (79%), sedentárias (68%), com uso de telas (85%) em tempo >3h/dia (44%). As mães eram as cuidadoras principais (90%). Foram significativamente associadas a escores mais elevados de QV: a condição de saúde típica (odds ratio — OR 2,38; intervalo de confiança de 95% — IC95% 1,60–3,55), o tempo de tela ≤2h/dia (OR 1,62; IC95% 1,17–2,24), o distanciamento social considerado “fácil” (OR 1,67; IC95% 1,20–2,32) e a família afirmar estimular a criança (OR 1,93; IC95% 1,08–3,45). Conclusões: Este estudo mostra que o contexto familiar pode influenciar a QV de crianças, especialmente no período de pandemia e de reorganização do ambiente domiciliar.

ABSTRACT Purpose: To evaluate the predictive value of initial intraocular pressure difference of the detached and fellow eyes of patients with complex rhegmatogenous retinal detachment on postoperative persistent ocular hypotony. Methods: This retrospective observational study included 538 eyes of 538 unilateral complex rhegmatogenous retinal detachment patients with a proliferative vitreoretinopathy grade of C-1 or higher, treated with silicone oil endotamponade following pars plana vitrectomy. The patients were divided into Group A (patients having silicone oil removal without ocular hypotony; n=504) and Group B (patients with persistent ocular hypotony following silicone oil removal [n=8, 23.5%] and with retained silicone oil [n=26, 76.5%] due to the risk of persistent ocular hypotony; total n=34). Ocular hypotony was defined as an intraocular pressure of <6 mmHg on two or more occasions. Patients’ demographics, including age, sex, and follow-up time, and ocular characteristics, including ocular surgical and trauma history, initial and final best-corrected visual acuity, intraocular pressure and initial intraocular pressure difference of the detached and fellow eyes, and anatomical success rates and postoperative complications, were retrospectively collected from the electronic patient files. Results: The initial intraocular pressure was significantly lower in the detached eyes of Group B than in Group A (8.3 ± 3.5 vs. 12.9 ± 3.3, p<0.001). Also, the initial intraocular pressure difference was significantly higher in Group B than in Group A (8.9 ± 3.2 vs. 2.2 ± 2.7mmHg, p<0.001). The receiver operating characteristic curve analysis showed that the cutoff value of the initial intraocular pressure difference was 7.5mmHg for the risk of persistent ocular hypotony. The most influential factors on postoperative persistent ocular hypotony in the binary logistic regression analysis were the initial intraocular pressure difference and the need for a retinectomy. Conclusion: In eyes with complex rhegmatogenous retinal detachment treated with pars plana vitrectomy and silicone oil tamponade, the initial intraocular pressure difference could be of value in predicting postoperative persistent ocular hypotony and could guide surgeons on the decision of silicone oil removal.

ABSTRACT Purpose: This prospective, randomized, unmasked, clinical trial aimed to report the visual outcomes of cataract surgery on both eyes versus cataract surgery on one eye in Brazilian patients. Methods: This study included patients with bilateral cataracts and binocular visual acuity worse than or equal to 0.3 logarithm of the minimum angle of resolution. The patients were randomly assigned to undergo surgery on one (Control Group) or both eyes (one eye at a time; Intervention Group). Postoperatively, self-reported visual function using Catquest-9SF (primary outcome measure), binocular visual acuity, stereopsis, and ocular dominance (secondary outcome measures) were compared. Results: A total of 151 patients (77 and 148 eyes in the Control and Intervention Groups, respectively) completed the follow-up. Patients who underwent surgery on both eyes exhibited significantly better self-reported visual function (p=0.036) and stereopsis (p=0.026) than those who underwent surgery on one eye. Binocular visual acuity and ocular dominance did not affect the group comparisons. Conclusions: Surgery on both eyes resulted in significantly better self-reported visual function and stereopsis than surgery on one eye.
