Identification of microorganisms in wet coffee fermentation Coffea arabica Var Catimor and Castillo in Jardín, Antioquia-Colombia, using culture-dependent methods / Identificación de microorganismos en fermentación húmeda de café Coffea arabica Var Catimor y Castillo en Jardín, Antioquia-Colombia, usando métodos cultivo-dependientes

Background: Mild Colombian coffees are recognized worldwide for their high-quality coffee cup. However, there have been some failures in post-harvest practices, such as coffee grain fermentation. These failures could occasionally lead to defects and inconsistencies in quality products and economic losses for coffee farmers. In Colombia, one of the fermentation methods most used by coffee growers is wet fermentation, conducted by submerging the de-pulped coffee beans for enough time in water tanks to remove the mucilage. Objectives: We evaluated the effect of the water (g)/de-pulped coffee (g) ratio (I: 0/25, II: 10/25, III: 20/25) and final fermentation time (24, 48, and 72 hours) on the total number of microbial groups. We also identified microorganisms of interest as starter cultures. Methods: We used a completely randomized experimental design with two factors; the effect of the water (g)/de-pulped coffee (g) ratio (I: 0/25, II: 10/25, III: 20/25) and final fermentation time (24, 48, and 72 hours), for 9 treatments with two replicates. During the coffee fermentation (1,950 g), the pH and °Brix were monitored. Total counts of different microbial groups (mesophiles, coliforms, lactic-acid bacteria, acetic-acid bacteria, and yeasts) were performed. Various isolates of microorganisms of interest as starter cultures (lactic-acid bacteria and yeasts) were identified using molecular sequencing techniques. Results: 21 lactic-acid bacteria (LAB) isolates and 22 yeasts were obtained from the different mini-batch fermentation systems. The most abundant lactic-acid bacteria species found were Lactiplantibacillus plantarum (46%) and Levilactobacillus brevis (31%). Pichia kluivery (39%) and Torulaspora delbrueckii (22%) were the most abundant yeast species. Conclusion The studied factors did not have effect over the microorganism's development. The identified bacterial and yeasts species have potential as starter cultures for better-quality coffees and in fermentation-related applications.

Antecedentes: Los cafés suaves lavados colombianos son reconocidos a nivel mundial por su buena puntuación sensorial; sin embargo, se han detectado fallas en las prácticas de postcosecha, como lo es la fermentación de los granos de café. Dichas fallas pueden causar defectos y carecer de consistencia en la calidad del producto, ocasionando pérdidas económicas para los caficultores. En Colombia, uno de los métodos más usados por los caficultores es la fermentación húmeda, la cual consiste en sumergir los granos de café despulpado en tanques con agua por un período de tiempo que permita la remoción del mucílago. Objetivos: La presente investigación evaluó la incidencia que tienen la proporción agua/granos despulpados de café (I: 0/25, II: 10/25, III: 20/25) y el tiempo final de fermentación (24, 48 y 72 horas) en el recuento final de grupos microbianos. Por otra parte, se identificaron taxonómicamente microorganismos de interés para su uso como cultivos iniciadores. Métodos: Mini-lotes consistieron en café despulpado (1950 g) puesto en recipientes de plástico abiertos y sumergidos en agua. Se aplicó un diseño experimental completamente aleatorizado de dos factores (proporción agua/ granos de café despulpado y tiempo) a tres niveles, para un total de nueve tratamientos con dos replicas. Durante las fermentaciones de café (1,950 g), el pH y los grados ºBrix, fueron monitoreados. Se realizaron los recuentos totales de los diferentes grupos microbianos: mesófilos, coliformes, bacterias ácido-lácticas, bacterias ácido-acéticas y levaduras. Se identificaron molecularmente diferentes aislados con potencial para ser usados como cultivos iniciadores (bacterias ácido-lácticas y levaduras). Resultados: Los resultados obtenidos mostraron que no hubo diferencia estádisticamente significativa entre los tratamientos aplicados y el recuento final de microorganismos. Un total de 21 aislados de bacterias ácido-lácticas (BAL) y 22 levaduras lograron obtenerse a partir de los diferentes sistemas de fermentación en mini-lote. Las especies de bacterias ácido-lácticas con mayor porcentaje acorde a su identificación taxonómica, corresponden a Lactiplantibacillus plantarum (46%), Levilactobacillus brevis (31%). Las especies de levaduras con mayor porcentaje acorde a su identificación taxonómica corresponden a Pichia kluivery (39%) y Torulaspora delbrueckii (22%). Conclusión Los factores estudiados no afectaron el crecimiento de ninguno de los grupos microbianos presentes en la fermentacion del café. Las especies de microorganismos identificados tienen potencial para se usados como cultivos starter o en aplicaciones dentro de las ciencias de fermentación.

El lugar como categoría espacial para los estudios sociales

El artículo sistematiza una concepción teórica y metodológica que sustenta el lugar como categoria espacial, dimensión de la existencia, a partir de la cual se materializan los objetos, fenómenos y procesos que se relacionan con la forma en la que se vive, en identidad con el entramado social y territorial en el que se desarrolla. A partir de la crítica de las fuentes bibliográficas registradas, emerge la espacialidad, en la que se insertan e imbrican los objetos de diverso carácter, la sociedad y sus acciones en su disposición, articulación y localización. El presente artículo deriva de un grupo de resultados del proyecto de investigación Proyección pedagógica de la Tarea Vida en los diferentes niveles educativos que se ejecuta en la Universidad de Camagüey Ignacio Agramonte Loynaz en el período enero 2020 - diciembre 2025 y tiene como objetivo sistematizar una concepción teórica y metodológica que sustente el estudio del lugar como categoría espacial para los estudios sociales. Entre los resultados se destaca la caracterización de las funciones del lugar; así como su comprensión como sistema, en el que están presentes dos totalidades, las que, en calidad de dimensiones, definen los atributos y características propias que trascienden el sistema; como un conjunto complejo de relaciones de carácter biofísico y cultural, sostenidas teóricamente desde su evolución, vistas desde una concepción práctico-actitudinal-espacial.

The article systematizes a theoretical and methodological conception that sustains the place as a spatial category, dimension of existence, from which the objects, phenomena and processes that are related to the way we live are materialized, in identity with the framework, social and territorial in which we develop. From the critique of the registered bibliographical sources, spatiality emerges as a process in which objects, processes of diverse character, society and its actions are inserted and intertwined in their arrangement, articulation and location. This article derives from a group of results from the research project Pedagogical projection of the Life Task at the different educational levels that is carried out at the University of Camagüey Ignacio Agramonte Loynaz in the period January 2020-December 2025 and aims to systematize a conception theoretical and methodological that supports the study of place as a spatial category for social studies. . Among the results, the characterization of the functions of the place stands out; as well as its understanding as a dialectical totality, in which two totalities are present, which, as dimensions, define the attributes and characteristics that transcend the system; as a complex set of relationships of a biophysical and cultural nature, theoretically sustained since its evolution, seen from a practical-attitudinal-spatial conception.

Adormecimento psíquico e despertar do inconsciente na adolescência: uma aposta na palavra / Le sommeil psychique et l'éveil de l'inconscient à l'adolescence: un pari sur la parole / Psychic numbness and awakening of the unconscious in adolescence: betting on the word

Este artigo apresenta uma reflexão sobre os efeitos do contexto da cultura digital para a adolescência. Abordamos a adolescência na teoria psicanalítica desde as concepções freudianas até as elaborações contemporâneas. Retomamos a infância como fase constitutiva do sujeito e suas implicações para a adolescência para destacar os impasses experienciados pelos adolescentes na cultura digital. Destacamos os conceitos de saber, Outro e objeto como articulatórios para a compreensão da adolescência na contemporaneidade. Consideramos que o estatuto do saber sofreu transformações decorrentes da aliança entre o capitalismo e a digitalização e que essas transformações trazem implicações para o laço social, configurando o que chamamos de adormecimento psíquico. Por fim, apontamos a conversação de orientação psicanalítica como uma possibilidade no enfrentamento dos desafios que a cultura digital apresenta

Cet article présente une réflexion sur les effets du contexte de la culture numérique sur l'adolescence. Nous analysons l'adolescence dans la théorie psychanalytique à partir des conceptions freudiennes jusqu'aux élaborations contemporaines. Nous revenons sur l'enfance en tant que phase constitutive du sujet et ses implications pour l'adolescence afin de mettre en évidence les impasses vécues par les adolescents dans la culture numérique. Nous mettrons en évidence les concepts de connaissance, d'Autre et d'objet comme des articulations fondamentales pour la compréhension de l'adolescence à l'époque contemporaine. Nous considérons que le statut du savoir a subi des transformations résultant de l'alliance entre capitalisme et numérisation et que ces transformations ont des implications sur le lien social, configurant ce que nous appelons le sommeil psychique. Enfin, nous indiquons la conversation psychanalytique comme une possibilité pour faire face aux défis que présente la culture numérique.

This article presents a reflection on the effects of digital culture on adolescence. We analyze adolescence in psychoanalytic theory from Freudian conceptions to contemporary elaborations. We return to childhood as a constitutive phase of the subject and its implications for adolescence in order to highlight the impasses experienced by adolescents in the digital culture. We highlight the concepts of knowledge, Other and object as articulations for the understanding of adolescence nowadays. We consider that the status of knowledge has undergone transformations resulting from the alliance between capitalism and digitalization and that these transformations have implications for the social bond, configuring what we call psychic numbness. Finally, we point out the psychoanalytic conversation as a possibility in facing the challenges that digital culture presents.

Production of dendritic cell vaccines using different methods with equivalent results: Implications for emerging centers

Introduction Dendritic cell (DC) vaccines have demonstrated good efficacy in preventing relapse and in increasing survival of patients affected by a variety of both solid and hematological tumors. Most protocols used to generate these cells involve the automated separation of peripheral blood monocytes from patients. This approach requires specialized equipment, which elevates the cost of this type of therapy, potentially limiting the widespread access to patients. Method: In this study, we compare the yield and quality of dendritic cells generated from monocytes and isolated by an automated method or by manual methods using gradient centrifugation. Results The results demonstrate the equivalence of the 3 methods in relation to the yield and final quality of the product, however with considerable differences between the costs of these procedures. In addition, this study also demonstrates the feasibility of the antigenic pulse with autologous tumor cell lysates, constituting a source of antigens, not only easily obtained and manipulated, but also specific to the patient's tumor. Conclusion These findings may have important implications for emerging centers interested in using this medical approach and potentially increase the access of a greater number of patients to this therapeutic option.

La cosmovisión indígena en políticas públicas medioambientales para reducir la contaminación durante la pandemia del coronavirus / coronavirusIndigenous Worldview in Environmental Public Policies to Reduce Pollution during the Coronavirus Pandemic / A cosmovisão indígena nas políticas públicas ambientais de redução da poluição durante a pandemia do coronavírus

Introducción: consecuencia de la pandemia a causa del coronavirus (SARS-CoV-2), desde el 2020 ha aumen-tado la generación de los residuos con riesgo biológico o infeccioso, usados en los protocolos de biosegu-ridad por parte de la ciudadanía en general y el talento humano en salud. Ello generó un alto riesgo para salud y un aumento en el índice de contaminación ambiental y degradación de los recursos naturales, que hasta el momento ha superado las expectativas para su mitigación. Desarrollo: para contrarrestar el impacto del aumento en el índice de contaminación ambiental, se reflexiona sobre la necesidad de buscar acciones medioambientales para mitigar el daño y ampliar el concepto sobre el medio ambiente y la importancia de la interacción y codependencia del ser humano con la naturaleza. Se plantea la idea de retomar elementos conceptuales del conocimiento de las culturas indígenas sobre la visión holística del ambiente, partiendo de una cosmovisión indígena del buen vivir, donde el ambiente y el ser humano se encuentran en constante equilibrio y armonía. Conclusión: se pretende encontrar, desde la cosmovisión indígena, posibles abordajes conceptuales que mitiguen el impacto de la contaminación ambiental a causa del coronavirus, así como la formulación de acciones estratégicas para la adecuada gestión de estos residuos

Introduction: Since 2020, due to the the Coronavirus (SARS-CoV-2) pandemic, there has been an increase in generation of waste with biological or infectious risk used in biosafety protocols by the community and human resources in health, which, in turn, generates a high rate of pollution and environmental degradation of natural resources that has so far exceeded expectations for mitigation.Development: To reduce the impact of this problematic situation, a reflection was made to strengthen the current public policies and implement environmental actions that seek to mitigate the damage, but, above all, to change the concept of the environment and increase awareness about the importance of interac-tion and codependency of human beings with nature. The idea of retaking conceptual elements of the knowledge of indigenous cultures regarding the holistic vision of the environment is proposed, starting from a Quechua worldview of good living, where the environment and the human being are in constant balance and harmony. Conclusions:This study is intended to determine, from the indigenous worldview, the possible conceptual approaches that mitigate the environmental impact, as well as to formulate strategic actions for the adequate management of the resultant waste.

Introdução: como consequência da pandemia causada pelo Coronavírus (SARS-CoV-2), desde 2020 houve um aumento na geração de resíduos com risco biológico ou infeccioso utilizados em protocolos de bios-segurança pelo público em geral e talentos humanos em saúde; o que gerou um alto risco à saúde e um aumento no índice de contaminação ambiental e degradação dos recursos naturais que até agora tem superado as expectativas para sua mitigação. Desenvolvimento: para neutralizar o impacto do aumento do índice de contaminação ambiental, é feita uma reflexão sobre a necessidade de buscar ações ambien-tais para mitigar os danos, e ampliar o conceito de meio ambiente e a importância da interação e code-pendência do ser humano com a natureza. Propõe-se a ideia de retomar elementos conceituais do conhe-cimento das culturas indígenas sobre a visão holística do meio ambiente, partindo de uma cosmovisão indígena do bem viver, onde o meio ambiente e o ser humano estão em constante equilíbrio e harmonia. Conclusão: pretende-se encontrar a partir da visão de mundo indígena, possíveis abordagens conceituais que mitiguem o impacto da contaminação ambiental devido ao coronavírus, bem como a formulação de ações estratégicas para o gerenciamento adequado desses resíduos

Sentinel laboratory compliance with best practices in Burkina Faso's antimicrobial resistance surveillance network

Background: Standardising procedures is the best way to harmonise and strengthen the quality of laboratory-based antimicrobial resistance surveillance. Since 2018, Burkina Faso has developed and disseminated the national manual of procedures for performing antibiotic susceptibility tests in sentinel laboratories within its national antimicrobial resistance surveillance network. Objective: Our study aimed to assess these sentinel laboratories' compliance with good practices for antibiotics susceptibility tests. Methods: Four teams evaluated the antimicrobial resistance sentinel sites laboratories throughout Burkina Faso from 19 to 28 September 2022. Eighteen out of 19 sentinel laboratories were evaluated. A four-member technical committee designed and validated the evaluation tool composed of three Microsoft Excel sheets. The evaluation emphasised quality controls for culture media, antibiotic discs and compliance with antimicrobial susceptibility testing procedures by the laboratories. Excel software was used for data recording and graphs and table design. The free R software version 4.2.0 was used for descriptive statistics. An overall score below 80% was considered noncompliance. Results: Most (83.33%) of the sentinel laboratories conducted at least one quality control activity for culture media, and 66.67% conducted at least one quality control activity for antibiotic discs. Over three-quarters (76.47%) of the laboratories were more than 80% compliant with the modified Kirby Bauer antimicrobial susceptibility testing method. Conclusion: The evaluation revealed the noncompliance of sentinel laboratories with the national procedure manual, particularly in the quality control component. What this study adds: This study has provided baseline data on the sentinel laboratories' compliance with the national antimicrobial susceptibility testing procedures manual, particularly in areas performing quality control checks or meeting quality indicators for culture media and antibiotic discs.

Source and application of seed cells in bioartificial liver support system / 临床肝胆病杂志

So far， there are still no specific treatment methods for severe hepatitis and liver failure， resulting in a mortality rate of over 70%， and they are the difficulties in the treatment of critical illness in China and globally. Liver transplantation is currently the most effective treatment method for end-stage liver disease， but only 1%‍ ‍—‍ ‍2% of patients can receive the opportunity for organ transplantation. The bioartificial liver support system utilizes external mechanical， physical， and biological devices to remove various harmful substances accumulated in the patient’s body， compensate for the metabolic functions of the liver， supplement necessary substances， improve internal environment， promote the recovery of liver function， help patients get through the critical period， and save time for liver transplantation， and therefore， it is considered one of the important methods for the treatment of end-stage liver disease. Since hepatocytes are the core element of bioartificial liver， this article summarizes the sources of liver seed cells， 3D culture methods， and corresponding bioreactor culture systems and hopes to gradually solve the core issue of large-scale in vitro preparation of hepatocytes to obtain hepatocytes with adequate quantity and quality， which urgently needs to be addressed in clinical application.

@#Objective To investigate the surface properties of different fibracel carriers and their culture effects on different cells.Methods Three fibracel carriers(A,B,C)were selected to analyze the chemical element composition of their materials,and the contact angles of the carriers before and after pretreatment with 0. 1 mol/L NaOH solution were tested. By measuring the adhesion effect and glucose consumption of Vero,MDCK and MRC-5 cells on the carrier,and observing the cell growth state by fluorescent staining,the cell adhesion efficiency and culture effect of the three carriers were compared and analyzed.Results The three carriers were mainly composed of C,H,O,and contained a small amount of N and S elements. Before pretreatment,the contact angle of carrier B was 0°,which was significantly lower than that of A[(109 ± 3. 13)°]and C[(121 ± 6. 82)°]（each F = 709. 1,each P < 0. 000 1）,and the hydrophilicity was stronger. Carriers A and C had poor hydrophilicity. After pretreatment,the contact angles of the surfaces of the three carriers A,B,and C were all 0°,with no significant difference(F = 0. 069 4,P > 0. 05),all of which were hydrophilic. The adherence rates of the three types of carriers within 3 h of cell culture were all above 80%. The cells were dense and evenly grown on the carrier fibers,the glucose consumption curves tended to“S”type,and the continuous cell culture effect was good. The total glucose consumption of carrier A and carrier C was basically the same,and carrier B was lower than carrier A and carrier C.Conclusion The chemical element composition and the relationship between the hydrophilic and hydrophobic properties of the three fibracel carriers were analyzed,and the adhesion rate and culture effect of Vero,MDCK and MRC-5 cells were evaluated,which provide reference for the subsequent research and production application of fibracel carriers.

Objective To investigate the isolation and culture of porcine bone marrow mesenchymal stem cell (BMSC) with α-1, 3-galactosyltransferase (GGTA1) gene knockout (GTKO), GTKO/ human CD46 (hCD46) insertion and cytidine monopho-N-acetylneuraminic acid hydroxylase (CMAH)/GGTA1 gene knockout (Neu5GC/Gal), and the protective effect of co-culture with porcine islets on islet cells. Methods Bone marrow was extracted from different transgenic pigs modified with GTKO, GTKO/hCD46 and Neu5GC/Gal. Porcine BMSC were isolated by the whole bone marrow adherent method and then cultured. The morphology of BMSC was observed and the surface markers of BMSC were identified by flow cytometry. Meantime, the multi-directional differentiation induced by BMSC was observed, and the labeling and tracing of BMSC were realized by green fluorescent protein (GFP) transfection. The porcine BMSC transfected with GFP were co-cultured with porcine islet cells. Morphological changes of porcine islet cells were observed, and compared with those in the porcine islet cell alone culture group. Results BMSC derived from pigs were spindle-shaped in vitro, expressing biomarkers of CD29, CD44, CD73, CD90, CD105 and CD166 rather than CD34 and CD45. These cells were able to differentiate into adipocytes, osteoblasts and chondrocytes. Porcine BMSC with GFP transfection could be labeled and traced, which could be stably expressed in the daughter cells after cell division. Porcine BMSC exerted certain protective effect on islet cells. Conclusions GFP-labeled porcine BMSC modified with GTKO, GTKO/hCD46 and Neu5GC/Gal are successfully established, which exert certain protective effect upon islet cells.
