RESUMO
A potential alternative to the use of chemical products with oomyceticidal action for the control of Phytophthora capsici in vegetables is the use of antimicrobial metabolites, biosynthesized in Bacillus species. The objective of this study was to induce the biosynthesis of lipopeptides in Bacillus amyloliquefaciens KX953161.1 by using glutamic acid, iron, cellulose, chitin, or inactive Colletotrichum spp. cells. The in vitro oomyceticidal effect of the bacterial lipopeptides on zoospores of Phytophthora capsici was evaluated. The lipopeptides identified and quantified in the crude extracts by high performance thin layer chromatography (HPTLC) were fengycin and surfactin. The bacterial culture with inactive fungal cells yielded the greatest biosynthesis of lipopeptides, at 1847.02± 11.8 and 2563.45± 18.4 µg/ml of fengycin and surfactin, respectively and the treatments that obtained lower production of these lipopeptides, were those to which iron and cellulose were added with 608.05 ± 22.6 and 903.74± 22.1; 563.31± 11.9 and 936.96± 41.1 µg/ml for fengicin and surfactin, respectively. The lipopeptide extracted showed 100% germination inhibition on zoospores of P. capsici, revealing encystment, malformations in the germ tube and cellular degradation. Lipopeptides have the potential to control P. capsici; however, the biosynthesis of these lipopeptides requires further study to determine their biological mode of action and optimize lipopeptide performance and profile.

A supercritical CO2 method was optimized to recover naringenin-rich extract from Mexican oregano (Lippia graveolens), a flavanone with high antioxidant and anti-inflammatory activity. The effect of the extraction parameters like pressure, temperature, and co-solvent on naringenin concentration was evaluated. We used response surface methodology to optimize the naringenin extraction from oregano; the chemical composition by UPLC-MS of the optimized extract and the effect of simulated gastrointestinal digestion on its antioxidant capacity and total phenolic content were also evaluated. The optimum conditions were 58.4 °C and 12.46% co-solvent (ethanol), with a pressure of 166 bar, obtaining a naringenin content of 46.59 mg/g extract. Also, supercritical optimized extracts yielded high quantities of cirsimaritin, quercetin, phloridzin, apigenin, and luteolin. The results indicated that the naringenin-rich extract obtained at optimized conditions had higher total phenolic content, antioxidant capacity by TEAC and ORAC, and flavonoid content, compared with the methanolic extract, and the simulated gastrointestinal digestion reduced all these values.

The inflammatory process, although beneficial, can produce tissue damage and systemic damage when uncontrolled. Effective therapeutic alternatives with little or no side effects are of great therapeutic interest. This study aimed to determine the phytochemical composition of bark extracts from J. cordata, an endemic plant from México, and evaluate their in vitro anti-inflammatory activity. Hexane, ethyl acetate, and methanol extracts were characterized by qualitative phytochemical tests, and their bioactive groups were identified by 1H NMR and gas chromatography coupled to mass spectrometry (GC-MS). The extract's anti-inflammatory activity was evaluated as nitric oxide (NO) production and their cytotoxicity by an MTS cell proliferation assay in lipopolysaccharide (LPS)-activated RAW 264.7 cells at concentrations of 1-100 µg/mL. The hexane extract contained fatty acids, fatty esters, phytosterols, alkanes, vitamin E, and terpenoids; the ethyl acetate extract showed fatty acids, fatty esters, aromatic aldehyde, phytosterols, vitamin E, and terpenoids, while the methanolic extract showed fatty esters, fatty acid, aromatics aldehydes, and alcohol. The ethyl acetate extract showed the highest inhibition of NO production, followed by the methanolic extract and the hexane extract, without affecting the viability of RAW 264.7 macrophage cells. The results suggest that J. cordata extracts are a potential source of bioactive compounds with anti-inflammatory potential.
RESUMO
Mexican oregano (Lippia graveolens) is an important source of bioactive compounds, such as flavonoids. These have presented different therapeutic properties, including antioxidant and anti-inflammatory; however, their functionality is related to the quantity and type of compounds, and these characteristics depend on the extraction method used. This study aimed to compare different extraction procedures to identify and quantify flavonoids from oregano (Lippia graveolens). Emerging and conventional technologies include maceration with methanol and water, and ultrasound-assisted extraction (UAE) using deep eutectic solvents (DES) such as choline chloride-ethylene glycol, choline chloride-glycerol, and choline chloride-lactic acid. Supercritical fluid extraction using CO2 as a solvent was also studied. Six different extracts were obtained and the total reducing capacity, total flavonoid content, and antioxidant capacity by ABTSâ¢+, DPPHâ¢, FRAP, and ORAC were evaluated. In addition, flavonoids were identified and quantified by UPLC-TQS-MS/MS. Results showed that UAE-DES had the best extraction effect and antioxidant capacity using colorimetric methods. However, maceration-methanol was superior in compound content, and highlighting naringenin and phloridzin were the major compounds. In addition, this extract was microencapsulated by spray drying, which provided a protection feature of their antioxidant potential. Oregano extracts are rich in flavonoids and the microcapsules present promising results for future research.
RESUMO
Medicines for chronic inflammation can cause gastric ulcers and hepatic and renal issues. An alternative treatment for chronic inflammation is that of natural bioactive compounds, which present low side effects. Extracts of Jatropha cordata (Ortega) Müll. Arg. have been evaluated for their cytotoxicity and anti-inflammatory activity; however, testing pure compounds would be of greater interest. Campesteryl palmitate, n-heptyl ferulate, palmitic acid, and a mixture of sterols, i.e., brassicasterol, campesterol, ß-sitosterol, and stigmasterol, were obtained from an ethyl acetate extract from J. cordata (Ortega) Müll. Arg. bark using column chromatography. The toxicity and in vitro anti-inflammatory activities were evaluated using RAW 264.7 murine macrophage cells. None of the products assessed exhibited toxicity. The sterol mixture exhibited greater anti-inflammatory activity than the positive control, and nitric oxide (NO) inhibition percentages were 37.97% and 41.68% at 22.5 µg/mL and 30 µg/mL, respectively. In addition, n-heptyl ferulate decreased NO by 30.61% at 30 µg/mL, while campesteryl palmitate did not show anti-inflammatory activity greater than the positive control. The mixture and n-heptyl ferulate showed NO inhibition; hence, we may conclude that these compounds have anti-inflammatory potential. Additionally, further research and clinical trials are needed to fully explore the therapeutic potential of these bioactive compounds and their efficacy in treating chronic inflammation.
RESUMO
OBJECTIVE: In Latin America is not known for certain the quantity or quality of therapeutic communities (TCs) available in the region. The objective of this study is to describe and quantify the quantity and quality of the existing TCs in 5 different countries. DESIGN: A multicenter quantitative description of the TCs was conducted in Argentina, Brazil, Colombia, Mexico and Peru. METHODS: A survey was realized through the TCs regulatory entities of each country that accepted to participate in the study. RESULTS: Of the 285 TCs identified in the 5 countries, 176 (62%) accepted to participate in this study. The TCs quality vas evaluated according to the scoring system stablished by De Leon, finding that 70% of the facilities have scores of 11/12 or 12/12 using these criteria. We also found that the majority of the De Leon criteria are known by more than 90% of the institutions, however, the dimensions of "separation of the community" and "encounter groups between residents" were the least known with 63 and 85% respectively. The main reasons for abandonment of TCs were "not accepting the rules of the institution", "lack of money" and "not feeling comfortable with the facilities". 98% of the TCs provided services to other substance abuse problems, 94% for alcohol and 40% for other types of substances. CONCLUSIONS: The majority of the TCs identified in our sample meet the quality criteria stablished by De Leon, mostly providing services for substance abuse. However, they should put in place additional policies to improve the unfulfilled conditions and investigate the reasons for the dissatisfaction and abandonment of these institutions.

Resumen La aplicación de metabolitos antimicrobianos biosintetizados por especies de Bacillus es una alternativa potencial para controlar Phytophthora capsici (P. capsici) en hortalizas y podría evitar el uso de productos químicos con acción oomiceticida. El objetivo de este estudio fue evaluar el impacto de la adición al medio de cultivo de distintos agentes (ácido glutámico, hierro, celulosa, quitina y células inactivas de Colletotrichum spp.) sobre la biosíntesis de lipopéptidos en Bacillus amyloliquefaciens KX953161.1 y examinar la capacidad oomiceticida de dichos compuestos in vitro sobre las zoosporas de P. capsici. Los lipopéptidos identificados y cuantificados por cromatografía en capa fina de alta resolución (HPTLC) en los extractos crudos fueron fengicina y surfactina. El cultivo bacteriano adicionado con células inactivas de Colletotrichum spp. demostró la mayor biosíntesis de lipopéptidos: 1.847,02 ±11,8 pg/mL de fengicina y 2.563,45 ± 18,4 pg/mL de surfactina. Los tratamientos con menor producción de estos lipopéptidos fueron aquellos a los que se añadió hierro (608,05 ± 22,6 pg/mL de fengicina y 903,74 ±22,1 pg/mL de surfactina) o celulosa (563,31 ±11,9 y 936,96 ±41,1 pg/mL, igual orden). El extracto con los lipopéptidos presentó una inhibición del 100% en la germinación de zoosporas de P. capsici, se observó enquistamiento, malformaciones en el tubo germinal y degradación celular. Se concluye que los lipopéptidos producidos por B. amyloliquefaciens KX953161.1 podrían contribuir al control de P. capsici, sin embargo, se requieren más estudios a fin de elucidar el modo de acción biológica de estos compuestos y optimizar el perfil de producción y el rendimiento.

RESUMO
Oregano phenolic compounds have been studied for their anti-inflammatory properties. Nonetheless, after ingestion, the gastrointestinal environment can affect their antioxidant stability and thus their bioactive properties. To evaluate the effect of in vitro gastrointestinal (GI) digestion on the phenolic compounds of 3 species of oregano (Hedeoma patens, Lippia graveolens, and Lippia palmeri), the total reducing capacity, total flavonoid content, and antioxidant capacity were evaluated before and after in vitro GI digestion. In addition, the phenolic compounds of the 3 oregano species were identified and quantified by UPLC-PDA before and after in vitro GI digestion. It was shown that the reducing capacity, flavonoid content and antioxidant capacity were affected by the GI digestion process. Moreover, the phenolic compounds identified were apigenin-7-glucoside, scutellarein, luteolin, luteolin-7-glucoside, phloridzin and chlorogenic acid, and their levels were affected by the in vitro GI process. Our results showed that the phenolic compounds from these 3 species of oregano are affected by the in vitro digestion process, and this effect is largely attributable to pH changes. These changes can modify the bioavailability and further anti-inflammatory activity of oregano phenolics, and thus, further research is needed. PRACTICAL APPLICATION: Oregano is a rich source of polyphenols that have shown bioactive properties like anti-inflammatory potential. However, little is known of the gastrointestinal fate of oregano polyphenols which is imperative to fully understand its bioaccessibility. Our results are important to develop new administration strategies which could help protect the antioxidant and anti-inflammatory potential and bioaccessibility of such compounds.

BACKGROUND: In Latin America, substance related disorders are highly prevalent and one of the treatment strategies is the Therapeutic Communities (TCs), however, in Latin America there is scarce data about this treatment strategies, their quality, drop-out rates and patient satisfaction. METHODS: Based on a previous study in 5 Latin American countries, the TCs who had a score equal or higher than 9 according to the De Leon criteria which are some fundamental items that the TCs should meet, were selected to carry out a descriptive and retrospective study of qualitative and quantitative characteristics of the TCs. RESULTS: Data from 58 TCs in 5 countries were included, with a sample of 1414 patients interviewed, of which most were single men, with no hospitalization history in a therapeutic community. Marijuana was the most commonly substance used in the 30 days prior to hospitalization, with 78% of interviewees referring alcohol consumption in the last 6 months and an average onset of psychoactive substances at 16 years of age. A 79% of the patients interviewed perceived some improvement during their stay in the TCs. The less fulfilled Quality Indicators by the TCs were "Requesting a professional qualification to former addicts that belonged to the program" and "Work as part of the therapeutic program". Among the reasons for discharge found in the database, 44% were due to therapeutic discharge with fulfillment of the treatment plan and 44% withdraws. CONCLUSION: The user satisfaction with TCs, in terms of infrastructure and quality are quite high, as the fulfillment of essential quality items, however, the follow up information to evaluate effectiveness of the treatment is poor or in some cases unknown.

Resumen Se buscó identificar las motivaciones que llevan a los hombres gay del AMBA (Área Metropolitana de Buenos Aires) a romper el Aislamiento Preventivo Social Obligatorio (APSO) con fines de encuentro sexual en el contexto de la pandemia de covid-19. Se realizó un estudio cualitativo-exploratorio, con veinte entrevistas semiestructuradas a igual número de personas. La muestra fue intencional no representativa, el contacto se estableció mediante la aplicación de GRINDR y TINDER pactando las entrevistas de manera telefónica o presencial. Se encontró que los entrevistados habían roto la cuarentena motivados principalmente por "la calentura", la dificultad para mantener "la abstinencia sexual" y por las "ganas de tener sexo", en el contexto de una alta valoración personal de la libertad y de familiaridad con la clandestinidad. Algunos realizan medidas de disminución del riesgo de covid-19, como el uso de cubrebocas y alcohol en gel, otros consideran que no son población en riesgo.
Abstract We aimed to identify the motivations of gay men on the AMBA to break the governmental policy of Obligatory Preventive Social Isolation (APSO) with the purpose of sexual encounter. We designed a qualitative-exploratory study, where twenty semi-structured interviews were applied to equal number of gay men. The sample was intentional and not representative, the contact was established through the application of GRINDER and TINDER arranging the interviews by telephone or in person. We found that interviewees have broken quarantine mainly motivated by "the fever", the difficulty of keeping the "abstinence", and the "desire to have sex", in the context or a highly personal value of freedom and the familiarity with clandestine behavior. Some took measures to lower the risk of covid-19, by using covered mouths and alcohol-based gel, others mentioned that they are not part of a risk group.

RESUMEN Objetivo: En Latinoamérica no se conoce a ciencia cierta la cantidad o la calidad de las comunidades terapéuticas disponibles en los distintos países de la región. El objetivo de este estudio es identificar y describir la cantidad y la calidad de las comunidades terapéuticas existentes en 5 países de la región. Diseño: Se realizó un estudio multicéntrico descriptivo cuantitativo de las comunidades terapéuticas en Argentina, Brasil, Colombia, México y Perú. Métodos: Mediante las entidades reguladoras de las comunidades terapéuticas de cada país, se realizó una encuesta a las que aceptaran participar en el estudio. Resultados: De las 285 comunidades terapéuticas identificadas en los 5 países, 176 (62%) aceptaron participar en el estudio. La calidad de las comunidades terapéuticas se evaluó por las puntuaciones establecidas con los criterios de De León; se encontró que el 70% de las instituciones tienen puntuaciones de 11/12 o 12/12 según estos criterios. También se encontró que cumplen la mayoría de los criterios de De León más del 90% de las instituciones; sin embargo, las dimensiones «separación de la comunidad¼ y «grupos de encuentro entre residentes¼ fueron los menos cumplidos (el 63 y el 85% de las comunidades respectivamente). Las principales razones de abandono de las comunidades terapéuticas fueron no aceptar las normas de la institución, falta de recursos económicos y no sentirse a gusto con ella. El 98% de las comunidades terapéuticas prestaban servicios para problemas de abuso de otras sustancias, el 94% para abuso de alcohol y el 40% para otros tipos de abusos. Conclusiones: La mayoría de las comunidades terapéuticas identificadas en nuestra muestra cumplen los criterios de calidad establecidos por De León, y en su gran mayoría prestan servicios para abuso de sustancias, pero deben instaurarse políticas para mejorar las condiciones no cumplidas e indagar los motivos de las disconformidades y el abandono de estas instituciones.

Esta investigación estudia el sufrimiento psíquico de mujeres en contexto de Pandemia provocado por el COVID-19 en el año 2021/22 Objetivos Determinar si mujeres perciben algún cambio con respecto a su salud mental y cuál es el nivel de sufrimiento psíquico por el que atraviesan en el contexto de la Pandemia. MÉTODOS La muestra está compuesta por 1589 mujeres mayores pertenecientes a barrios vulnerables de diferentes ciudades. Es un estudio de carácter multicéntrico y colaborativo, responde a un diseño descriptivo de corte transversal, entre cinco ciudades de la República Argentina: Córdoba, Santa Rosa, Villa Mercedes, Rafaela y Orán. Según los objetivos propuestos se optó por una estrategia cuantitativa. RESULTADOS De los datos obtenidos sobre la percepción que tienen las mujeres, en las localidades agrupadas, sobre el sufrimiento psíquico antes de la pandemia, se puede decir que, el 64% (1016) de las mujeres manifestó tener un sufrimiento bajo, el 22% (343) sufrimiento medio y el 15% (230) sufrimiento alto. Teniendo en cuenta los puntajes equivalentes al sufrimiento medio y alto, se puede decir que más del 37% de las mujeres entrevistadas percibieron tener antes de la pandemia, un nivel de sufrimiento significativo. En cuanto a los datos obtenidos en los instrumentos prepandemia y pandemia, se observa que en la percepción del sufrimiento ''bajo'' el porcentaje disminuyó un 21%, en el sufrimiento ''medio" hay un 7% de aumento y en el sufrimiento ''alto'' un aumento del 14%, esto quiere decir que 222 mujeres manifestaron un incremento en el sufrimiento psíquico durante la pandemia, respecto a la pre pandemia; si se asocia el sufrimiento ''medio'' y ''alto'', se puede decir que, el sufrimiento tuvo un aumento del 21%, en 333 mujeres. DISCUSIÓN La categoría de soledad presenta el mayor porcentaje. La sumatoria de los valores del sufrimiento medio y alto de todas las categorías, representa un 59% de mujeres con un nivel significativo de sufrimiento.
