Abstract (Introduction): Vinasse is generated as a residue in the production of ethanol by fermentation-distillation of molasses/sugar cane juice, at a rate of 13 L/L of ethanol. It is an acid liquid, brown in color, characterized by high mineralization and Chemical Oxygen Demand (COD) values of up to 150 000 mg/L, being highly polluting. (Objective): The objective of this research was to evaluate a vinasse treatment process with hydrogen peroxide as a source of hydroxyl radicals at laboratory scale. (Methodology): The vinasse samples, from different distilleries in the province of Tucumán, were characterized following standardized techniques of Standard Methods. The oxidation tests were carried out with different peroxide/vinasses ratios, in a semi-batch reactor, under ambient conditions, measuring COD as an indicator parameter of the treatment. (Results): After 5 days, an 85 % decrease in COD and an increase in the Biodegradability Index were achieved. The kinetics of the oxidative reaction was first order with respect to COD, with an apparent rate constant of 0.3694 1/day. (Conclusions): Although the COD values allowed by local regulations (250 mg/L) were not reached, the proposed treatment is encouraging due to its simplicity, representing a potential option to the environmental challenge represented by vinaze in Latin America.

La cinética de la reacción oxidativa fue de primer orden respecto de DQO, con una constante aparente de velocidad de 0.3694 1/día. (Conclusiones): Si bien no se lograron los valores de DQO permitidos por la normativa local (250 mg/L), el tratamiento propuesto es alentador por su simpleza, representando una opción potencial al desafío ambiental que representan las vinazas en América Latina.

BiOCl/KBiO3 p-n heterostructures with hierarchical mesoporous architectures were successfully synthesized via a facile in situ method. The X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and scanning electron microscope (SEM) results indicate the formation of heterojunctions between BiOCl and KBiO3. The photocatalytic performance of the as-prepared samples was investigated by the degradation of dye Rhodamine B (RhB) under visible light irradiation. BiOCl/KBiO3 composite has never been used to photodegrade the RhB which is a common dye and very difficult to degrade. The results demonstrated that KBiO3 combined with proper amount of BiOCl nanosheets exhibited high efficiency in the photocatalytic process, and BiOCl/KBiO3 with the molar ratio of 70/30 demonstrated the highest photocatalytic activity due to its large surface area, excellent charge separation characteristics and the suppressed recombination of electron-hole pairs. The results of active species detection reveal that the superoxide radical anions (O2-), hydroxyl free radicals (·OH), photogenerated holes (h+) and photogenerated electrons (e-) reactive species work together for the photocatalytic degradation of RhB. A possible and new mechanism of photocatalysis that differs from other teams was also explored and proposed. The present study will benefit the development of the new p-n heterojunction photocatalysts and would be of great importance to meet ever-increasing environmental demands in the future.

Acetic acid bacteria (AAB) are versatile organisms that catalyze the conversion of a wide range of carbon sources into biomolecules of great industrial interest. In this study, we exploited the ability of Gluconobacter spp. to synthesize levans. Among the isolated strains, Gluconobacter cerinus UELBM11 produced approximately 14.0 g L−1 of levan under non-optimized conditions. Gas chromatography-mass spectrometry (GC-MS), Fourier transform infrared spectroscopy (FTIR), and nuclear magnetic resonance (NMR) analyses confirmed that levan obtained from G. cerinus UELBM11 consisted of a β-(2→6)-D-fructose backbone with some β-(2→1) ramifications. The average molecular weight (Mw) of the purified levan was 8.78 × 105 Da. Thermogravimetric/differential thermogravimetric (TGA/DTG) analysis indicated high thermal stability, with the maximum decomposition rate observed at 227.44 °C. Scanning electron microscopy (SEM) revealed a microporous morphology, and the antioxidant activity assays demonstrated that levan had a high scavenging capacity of 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and hydroxyl radicals. Therefore, it has been demonstrated the levan produced by G. cerinus UELBM11 is a promising natural antioxidant and, owing to its microporosity and excellent thermal properties and stability, is a potential candidate as an additive in cosmetics, pharmaceuticals, and food products.

Two novel alkyl thiophene-modified pyrene derivatives (1)-(2) were created and synthesized using palladium-catalyzed Stille coupling processes and Friedel-Crafts reaction of pyrene. The polycyclic aromatic groups of the thiophene-modified pyrene were oxidized with Ag[Al(OC(CF3)3)4] to provide the insensitive radical cations 1•+-2•+ based on the alkyl thiophene-modified pyrene derivatives. Nuclear magnetic resonance (NMR), electron paramagnetic resonance (EPR), UV-Vis spectroscopy, and density functional theory (DFT) calculations, were used to investigate their structures and properties. The pyrene moieties were the primary location of the electron spin distribution, with a little overflow onto the outer thiophene moieties. Due to the different substituent groups, free radicals 1•+ 2•+ exhibit some different properties. Compound 1•+ is the most extensive thiophene-modified pyrene radical cation that has been reported. These species are anticipated to have wide-ranging potential in the areas of optoelectronic materials and semiconductors. thiophenemodified modified 12 1 2 (1)-(2 palladiumcatalyzed palladium catalyzed FriedelCrafts Friedel Crafts AgAlOCCF334 AgAlOCCF Ag Al OC CF3 3 4 CF Ag[Al(OC(CF3)3)4 1•+2•+ 1•+-2• NMR, NMR , (NMR) EPR, EPR (EPR) UVVis UV Vis spectroscopy DFT (DFT calculations properties distribution 1• 2• reported wideranging wide ranging semiconductors (1)-( AgAlOCCF33 Ag[Al(OC(CF3)3) 1•+2• 1•+-2 (NMR (EPR (1)- AgAlOCCF3 Ag[Al(OC(CF3)3 1•+2 1•+- (1) Ag[Al(OC(CF3) (1 Ag[Al(OC(CF3 ( Ag[Al(OC(CF

Abstract Introduction. In Mexico, 85 % of the crops are white maize, 10 % white yellow and 5 % other colors. Biochemical studies of pigmented native maize have been carried out, but there is little information on colour-improved maize. Objective. To evaluate the phytochemical content and antimicrobial capacity of two pigmented maize hybrids grown at the Tecnológico Nacional de México-Valle del Yaqui. Materials and methods. Extraction of biocompounds from a portion of the maize grains grown in southern Sonora, Mexico, during the summer-winter 2020 cycle was performed on red and purple maize hybrids. A thirty-part solution of ethanol, acetic acid and water was used. Proximal composition, anthocyanin, polyphenol and flavonoid content were determined by standardized methods. Antioxidant capacity was determined by ABTS (2,2’-azino-bis-(3-ethylbenzothiazoline-6-sulphonic acid)) and DPPH (2,2-diphenyl-1-picrylhydrazyl) methodologies. In addition, antimicrobial capacity and minimum inhibitory concentration were determined. Results. Purple maize showed higher content of anthocyanins (340.98±5.21 mg/100 g) and polyphenols (173.68±24.23 mg gallic acid/100 g) compared to red maize. Flavonoids are more abundant in purple maize (575.10±27.88 mg quercetin/100 g). Both maize hybrids exhibited more than 50 % antioxidant capacity against ABTS and DPPH radicals. Regarding antimicrobial activity, higher inhibition was observed for Escherichia coli and Salmonella (18 % and 47 %), and lower for Staphylococcus aureus and Shigella (19 % and 34 %) compared to gentamicin. Conclusion. Purple maize showed higher content of anthocyanins, polyphenols and flavonoids. Both hybrids had an antioxidant capacity higher than 50 %. Antimicrobial activity was higher against E. coli and Salmonella, than against S. aureus and Shigella.

Resumen La contaminación ambiental es uno de los factores que favorece el estrés oxidante, ya que expone al organismo a materiales diversos que generan radicales libres y afectan al sistema respiratorio, cardiovascular, inmunológico y nervioso de las personas más vulnerables como los niños, adultos mayores y personas con enfermedades crónicas. Para prevenir o reducir el estrés oxidante, el cual es un desequilibrio entre la producción de radicales libres y la capacidad del organismo de neutralizarlo, se recomienda consumir una dieta equilibrada y rica en antioxidantes naturales los cuales se encuentran diversos alimentos, especialmente en frutas y verduras con colores intensos, en las semillas y las especias. En las últimas décadas se ha demostrado la eficacia del consumo de antioxidantes naturales como: el resveratrol vino, el café, la curcumina, el ajo, la vitamina C, la vitamina E y el té verde que presentan efectos benéficos como: proteger membranas celulares, regular la expresión de genes relacionados con la inflamación, prevenir o reducir el daño endotelial, disminuir la frecuencia o severidad de enfermedades neurodegenerativas, hepáticas y pulmonares, así como estimular al sistema inmunológico.

Abstract Environmental pollution can promote oxidative stress by exposing the body to various elements and substances that generate free radicals, such as lead and vanadium. These free radicals can negatively impact the respiratory, cardiovascular, immune, and neurological systems of vulnerable populations, including children, the elderly, and those with chronic diseases. To prevent or reduce oxidative stress, it is recommended to consume a balanced diet rich in natural antioxidants. These antioxidants can be found in various foods, especially in fruits and vegetables with intense colors, seeds, and spices. In recent decades, the effectiveness of consuming natural antioxidants such as resveratrol found in wine, coffee, curcumin, garlic, vitamin C, vitamin E, and green tea has been demonstrated. These antioxidants have beneficial effects on the body, including the protection of cell membranes, regulation of gene expression associated with inflammation, prevention or reduction of endothelial damage, and the decrease or diminished severity of neurodegeneration, liver, and pulmonary disorders. Additionally, they stimulate the immune response.

Abstract: This article analyzes the discussions in the Preliminary Councils of the XXVII Legislature regarding the legitimacy of popular representatives, a discussion in which two political blocks confronted each other: that of the presumed deputies close to President Venustiano Carranza, known as the renovators, and the opposition block, known as the radicals, some of whom were close to Álvaro Obregón or Pablo González, two of the most important Constitutionalist leaders. This discussion reveals the emergent fractures in the triumphant current of the Mexican Revolution, which could first be seen in the Constitutional Congress of 1916-1917, a divide that would hold over into the XXVII Legislature and the one that followed. This division provoked fierce political struggles between congress and the Carranza administration and reduced the latter’s efficacy, as several of its most important initiatives, such as the law on the suspension of guarantees to combat the rebellions against his government, were blocked by the opposition, as they constituted the majority legislative block.

Resumen: Este artículo analiza la discusión en las Juntas Preliminares de la XXVII Legislatura acerca de la legitimidad de los representantes populares, discusión en la cual se enfrentan dos bloques, el de los presuntos diputados más cercanos al presidente Venustiano Carranza, conocidos como renovadores, y el de un bloque opositor, conocido como radical, algunos de cuyos miembros eran cercanos a Álvaro Obregón o a Pablo González, dos de los más importantes líderes del constitucionalismo. Esa discusión muestra la fractura que se estaba produciendo en la corrien te triunfadora de la Revolución, cuyos primeros signos se habían mostrado en el Congreso Constituyente de 1916-1917, división que continuó en la XXVII Legislatura y que se prolongaría también en la siguiente. Esa escisión provocó fuertes disputas políticas del Congreso con el gobierno de Venustiano Carranza y le restó eficacia a éste, pues varias de sus iniciativas más importantes, como la Ley de Suspensión de Garantías para poder combatir las rebeliones que estallaron en su gobierno, se vieron obstaculizadas por la oposición de un sector mayoritario de legisladores.

Resumen: El gel de Aloe vera es considerado una fuente natural de múltiples beneficios, originados por la acción combinada de vitaminas, aminoácidos, compuestos fenólicos, enzimas, minerales, ácidos orgánicos, lípidos y carbohidratos, que se relacionan con la mejora de enfermedades neuro-degenerativas como Alzheimer. Los ensayos in vitro e in silico permiten confirmar e identificar posibles beneficios de esta planta y sus compuestos en enfermedades. El objetivo del presente trabajo fue evaluar la actividad antioxidante del gel de A. vera y mediante análisis in silico, establecer el potencial terapéutico de sus compuestos bioactivos en la enfermedad de Alzheimer. Se obtuvieron hojas de A. vera, de las que se extrajo el gel, retirando el exocarpio, se liofilizó y almacenó hasta su uso. Se caracterizó la capacidad antioxidante, se cuantificaron los compuestos fenólicos y flavonoides y se analizó la relación que existe entre los parámetros mediante correlación de Pearson. Mediante análisis in silico se evaluó el potencial de interacción de 8 compuestos del gel con la proteína gamma secretasa. El gel de A. vera obtuvo alta capacidad antioxidante por ABTS, DPPH, radical OH y poder reductor, usando bajas concentraciones para inhibir el 50 % de los radicales, y correlaciones positivas con fenoles totales y flavonoides. En el estudio in silico el compuesto que presentó mejor unión con gamma secretasa fue aloe-emodina, con menor energía libre de unión y menor concentración de constante de inhibición, sugiriendo su potencial uso como coadyuvante en el tratamiento de la enfermedad de Alzheimer.

Abstract: Aloe vera gel is considered a natural source of multiple benefits, originated by the combined action of vitamins, amino acids, phenolic compounds, enzymes, minerals, organic acids, lipids and carbohydrates, which are related to the improvement of neuro-degenerative diseases such as Alzheimer’s. In vitro and in silico tests allow us to confirm and identify possible benefits of this plant and its compounds in diseases. The objective of the present study was to evaluate the antioxidant activity of A. vera gel and, through in silico analysis, to establish the therapeutic potential of its bioactive compounds in Alzheimer’s disease. A. vera leaves were obtained, from which the gel was extracted, removing the exocarp, lyophilized and stored until use. The antioxidant capacity was characterized, the phenolic compounds and flavonoids were quantified, and the relationship between the parameters was analyzed using Pearson correlation. The interaction potential of 8 compounds in the gel with the gamma secretase protein was evaluated through in silico analysis. The A. vera gel obtained high antioxidant capacity due to ABTS, DPPH, OH radical and reducing power, using low concentrations to inhibit 50 % of the radicals, and positive correlations with total phenols and flavonoids. In the in silico study, the compound that showed the best binding with gamma secretase was aloe-emodin, with lower binding free energy and lower inhibition constant concentration, suggesting its potential use as an adjuvant in the treatment of Alzheimer’s disease.

Abstract Cisplatin is an antineoplastic medicine used in the treatment for various types of cancer. Among its side effects is ototoxicity, which may result in a bilateral and irreversible hearing loss. The ototoxic effect in the pediatric population has a bigger impact as it compromises language acquisition. The discovery of drugs with otoprotective effects and the optimal way to administer them have become significant challenges in minimizing the impact of cisplatin regarding auditory function. The objective was to understand otoprotective drugs and their relevance in the preventive treatment to cisplatin-induced ototoxicity in childhood. An integrative review was conducted by consulting databases including PubMed, Bireme, MedLine, LILACS, SciELO, and ClinicalTrials.gov. The search strategy was performed by crossing descriptors (DeCS and MeSH) and free terms. Studies published in English, Spanish, and Portuguese were selected, with no publication year restrictions. Subsequently, articles were selected according to inclusion and exclusion criteria. A total of 736 articles were found in PubMed, 431 in Bireme, 425 in MedLine, 6 in LILACS, 0 in SciELO, and 4 in ClinicalTrials.gov. After document analysis, 12 articles were selected for full analysis. Evidence was found for 8 substances with potential otoprotective effects when used with cisplatin, which tend to minimize the impact of cisplatin regarding auditory function. The substances found were: Amifostine, Dexamethasone, Genistein, Ginkgo Biloba, Lycopene, N-acetylcysteine, Polydatin also Sodium Thiosulfate. In general, these drugs are applied before, during, or after cisplatin infusion, depending on the chosen drug, via intravenous, oral, or transtympanic injections, acting as antioxidant therapy. The biochemical effects of these substances are relevant to their potential otoprotective properties, including the inactivation of oxygen free radicals and electrophilic platinum species. The use of these substances can reduce ototoxicity, decreasing cisplatin-induced hearing loss and improving the confort of life, especially for children. cancer acquisition function cisplatininduced induced childhood PubMed Bireme MedLine LILACS SciELO ClinicalTrialsgov ClinicalTrials gov ClinicalTrials.gov DeCS MeSH terms English Spanish restrictions Subsequently criteria 73 43 42 analysis 1 Amifostine Dexamethasone Genistein Biloba Lycopene Nacetylcysteine, Nacetylcysteine N acetylcysteine, acetylcysteine N-acetylcysteine Thiosulfate general before during infusion drug intravenous oral injections therapy properties species life children 7

Abstracts It has been demonstrated that Lantana camara possesses several therapeutic properties that can be used to treat various human diseases, including dermatological and gastrointestinal conditions, tetanus, malaria, and tumours. In this investigation, every collected part of L. camara was extracted with absolute methanol to examine its antioxidant capacity using the DPPH assay and its anti-leukemia activity on two AML cell lines, MOLM-13 and MV4-11. In addition, anti-inflammatory effectiveness was evaluated. The results show that extracts from various sections of L. camara have a significant ability to neutralize free radicals, as indicated by their EC50 values. Most of the extracts had values less than 100 μg/ml, with the flower extract having an even lower value of less than 50 μg/ml. Experiments on two AML cell lines showed that the anti-leukemia effects of the extracts were remarkable, with the most potent impact belonging to the root extract (IC50 was 9.78 ± 0.61 and 12.48 ± 1.69 for MOLM-13 and MV4-11 cell lines). The antitumor effect of the extracts was determined to be time- and dose-dependent and did not correlate with antioxidant capacity. Furthermore, when BJ cells were exposed to L. camara root and leaf extracts, their migratory potential was dramatically reduced compared to untreated cells. The extracts demonstrated potential anti-inflammatory capabilities by lowering NO production in LPS-induced BJ cells. diseases conditions tetanus malaria tumours investigation L antileukemia anti leukemia MOLM13 MOLM 13 MOLM-1 MV411.

Resumo Foi demonstrado que Lantana camara possui diversas propriedades terapêuticas que podem ser utilizadas para tratar uma variedade de doenças humanas, incluindo condições dermatológicas e gastrointestinais, tétano, malária e tumores. Nesta investigação, cada parte coletada de L. camara foi extraída com metanol absoluto para examinar sua capacidade antioxidante utilizando o ensaio DPPH e sua atividade antileucêmica em duas linhagens celulares de LMA, MOLM-13 e MV4-11. Além disso, foi avaliada a eficácia anti-inflamatória. Os resultados mostram que os extratos de várias partes de L. camara têm uma capacidade significativa de neutralizar os radicais livres, como demonstrado pelos seus valores de EC50. A maioria dos extratos apresentava valores inferiores a 100 g/ml, com o extrato de flores apresentando um valor ainda mais baixo, inferior a 50 μg/ml. Experimentos em duas linhagens celulares de LMA mostraram que os efeitos antileucêmicos dos extratos foram notáveis, com o efeito mais forte pertencente ao extrato de raiz (IC50 foi 9,78 ± 0,61 e 12,48 ± 1,69 para linhas celulares MOLM-13 e MV4-11). O efeito antitumoral dos extratos foi determinado de maneira dependente do tempo e da dose e não se correlacionou com a capacidade antioxidante. Além disso, quando as células BJ foram expostas aos extratos de raiz e folhas de L. camara, o seu potencial migratório foi drasticamente reduzido em comparação com as células não tratadas.

Resumo Em razão dos graves efeitos colaterais causados pela maioria dos medicamentos antidiabéticos atualmente utilizados, continua a busca por novos medicamentos seguros para o controle do diabetes. As naftoquinonas, que possuem fortes propriedades antioxidantes, têm sido empregadas como candidatas à terapia do diabetes. O presente estudo visa encontrar o potencial antioxidante e hipoglicemiante de alguns novos derivados de 2-fenilamino-1,4-naftoquinonas (PAN), incluindo derivados de cloro, nitro, metil e bromo (5a-d) sintetizados por experimento em pote único. Os cristais do produto foram purificados por TLC e caracterizados por FT-IR. O potencial antioxidante dos compostos foi testado por meio de atividades de sequestro de radicais DPPH e redução de energia observada como absorção no UV-vis. O ensaio DPPH mostrou a poderosa atividade antioxidante dos derivados nitro e bromo, enquanto o derivado nitro mostrou o potencial de redução significativo para o ensaio FRAP. O potencial hipoglicêmico dos compostos foi estudado em modelo animal de rato. Todos os compostos sintetizados revelaram melhor atividade hipoglicemiante; no entanto, o derivado cloro apresentou atividade hipoglicêmica mais potente, com redução de 43% nos níveis médios de glicose no sangue dos animais tratados. Como a biorredução de naftoquinonas pode ser influenciada pela alteração de suas propriedades redox, notou-se que o efeito da doação eletrônica por ressonância (+R) do grupo “cloro” tem sido significativo na atividade biológica por meio da estabilização de sua forma imina, que limita o potencial de geração de radicais livres durante a biorredução de quinonas, e, portanto, tem sido proposto como a razão de sua atividade hipoglicemiante. Estudos futuros empregando as propriedades de grupos de doação eletrônica de PAN podem otimizar a interação droga-receptor para melhor planejamento de medicamentos e estratégias de desenvolvimento de medicamentos contra o diabetes e também para os ensaios clínicos.

Abstract Due to the severe side effects revealed by most of the currently used antidiabetic medicines, search for finding new and safe drugs to manage diabetes is continued. Naphthoquinones possessing strong antioxidant properties have been employed as candidates for diabetes therapy. Present study is aimed at finding the antioxidant and hypoglycaemic potential of some novel derivatives of 2-phenylamino-1,4-naphthoquinones (PAN) including chloro, nitro, methyl and bromo (5a-d) derivatives synthesized by single pot experiment. Product crystals were purified by TLC and characterized by FT-IR. The antioxidant potential of the compounds was assayed through DPPH radical scavenging and reducing power activities noted as UV-vis. absorbance. The DPPH assay has showed the powerful antioxidant activity of nitro and bromo derivatives, while the nitro derivative showed the significant reduction potential towards FRAP assay. Hypoglycaemic potential of the compounds was studied in rat animal model. All synthesized compounds revealed better hypoglycaemic activity; however, the chloro-derivative exhibited the more potent hypoglycaemic activity showing about 43% reduction in the mean blood glucose levels of the treated animals. As the bioreduction of naphthoquinones may be influenced by changing its redox properties, it has been noticed that the e-donating resonance effect (+R) of ‘chloro’ group has shown the significant effects on biological activity through stabalization of its imine form which limits the potential of generation of free radicals during bioreduction of quinones and thus has been proposed as the reason of its hypoglycaemic activity. Future studies employing the properties of e-donating groups of PAN may optimize the drug-receptor interaction for better drug designing and drug development strategies against diabetes and also for the clinical trials.
