Las caracteristicas unicas de los compuestos sintetizados por especies de origen marino van mas alla de su apariencia. Los pigmentos responsables de esos colores son capaces tambien de generar diversas actividades biologicas, como la capacidad antioxidante, la cual puede ocurrir a traves de diversos mecanismos. Esto ha propiciado un aumento de su investigacion, debido a su amplia aplicacion en la biotecnologia, farmaceutica, cosmetica y alimentacion de organismos vivos, expandiendo los estudios tanto in vitro como en ensayos in vivo. El objetivo de este trabajo fue compilar y describir diversos estudios recientes, enfocados en demostrar y elucidar los mecanismos de accion de los diferentes compuestos bioquimicos con actividad antioxidante, provenientes de algunos organismos marinos. Para ello, se utilizaron las bases de datos Scopus®, Web of Science™ y Microsoft Academic. Los pigmentos provenientes de organismos marinos representan una alternativa promisoria frente a los antioxidantes y aditivos sinteticos utilizados en la actualidad. El establecimiento y comprension de los mecanismos de accion de los componentes pigmentados bioactivos, aislados de los organismos marinos, permitira determinar con mayor precision su posible aplicacion en la industria.","PeriodicalId":42451,"journal":{"name":"CienciaUat","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2021-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45205289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ability of lactic bacteria to produce large amounts of lactic and acetic acid has the effect of decreasing the pH, considered one of the primary factors in the inhibition of undesirable microorganisms such as pathogens and coliform bacteria, in dairy foods. The objective of this work was to isolate lactic acid bacteria and evaluate their antagonistic effect against pathogenic bacteria in vitro, as well as their effect against pathogens that are present in milk when they are added in the preparation of cream cheese. Strains of lactic bacteria were isolated from cream cheese from Chiapas, Mexico. Isolates were identified by API 50CH biochemical tests and 16S ribosomal gene sequences. The bacteria under study were used in pathogen growth inhibition tests. The production of acetic and lactic acid was quantified by gas chromatography coupled to masses in the cheeses at the beginning and 10 d after its elaboration. 203 bacterial strains were isolated, 82 of which had the ability to inhibit the growth of 7 pathogenic bacterial strains. The strains were identified by the partial sequence of the 16S ribosomal gene as belonging to the genus Lactobacillus; The addition of these strains in the elaboration of cream cheese reduces or eliminates coliforms, Staphylococcus aureus, molds and yeasts, while in the cheese made with pasteurized milk 290 CFU/mL of molds and yeasts were detected. These results suggest that Lactobacillus strains isolated from Chiapas artisanal cream cheese has the potential to be used as a starter culture with bioconservation activity in this and similar products.","PeriodicalId":42451,"journal":{"name":"CienciaUat","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2021-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45683151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to assess the effect of bee honey as antioxidant on raw rabbit loin, refrigerated at 4 °C. The antioxidant activity (AA)of three types of honey was evaluated: dark, amber and clear, to be mixed with rabbit meat. Dark honey was selected for its higher antioxidant effect. 64 samples of 100 g of raw meat were prepared, 32 samples were mixed with 2 g dark honey and the other 32 were left without honey (control). The samples were stored at 4 °C and AA as well as malondialdehyde (MDA) concentrations were evaluated at 0 d, 3 d, 6 d and 9 d of storage. The AA decreased, and the MDA concentration increased (P < 0.05) with refrigeration time (changes that indicate meat spoilage). After 3 d and 6 d, the raw meat samples with honey showed higher AA (P < 0.05) and after 6 d, they showed lower MDA values (P < 0.05) compared to the control samples (these changes indicate no spoilage of meat). Dark bee honey contains high concentrations of natural antioxidants that protect ground raw rabbit loin against oxidative damage that can occur during refrigeration, therefore, its use is recommended for this purpose.","PeriodicalId":42451,"journal":{"name":"CienciaUat","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2021-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42915218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Una teoria aun vigente para comprender estos factores externos es la teoria de polos de desarrollo. El objetivo de la presente investigacion fue conocer la riqueza de especies vegetales comestibles versus ornamentales en patios familiares de 13 comunidades de Paso de Ovejas, Veracruz y la influencia que tiene en ello el polo de desarrollo mas cercano (cabecera municipal). Se aplico una encuesta consistente en 443 cuestionarios, a traves de un muestreo no probabilistico de tipo accidental. En el analisis de los datos se uso estadistica descriptiva e inferencial (componentes principales) y los indices de familiaridad (IF), valor de uso (IVU) y consenso del informante (ICF). Los resultados obtenidos sugieren que la riqueza de especies ornamentales versus comestibles esta relacionada con la lejania o cercania al polo de desarrollo. La influencia de este polo afecta la dinamica socioeconomica familiar, cuyos miembros, si bien evidencian un alto grado de familiaridad con las especies existentes en sus patios familiares, tambien expresan la generacion de condiciones de posibilidad para que parte de ellas (especies comestibles) puedan ser progresivamente abandonadas en su uso y manejo, como sucede en una comunidad de la ruta 3. Se concluye que, en la determinacion de la riqueza de especies del patio familiar interviene el polo de desarrollo, como un factor exogeno, el cual trastoca la dinamica familiar en las comunidades que lo circundan.

The evaluation included: 1) the piquin chili sample through two extraction solvents and 2) the supplemented and unsupplemented oil at 0 d, 7 d, 14 d, 21 d and 28 d after preparation (DPP). The piquin chili presented high antioxidant values. The analysis of variance (ANOVA) indicated that the aqueous extract surpassed the hydroalcoholic extract. The factorial ANOVA showed significant differences in the three antioxidant parameters evaluated. These dissimilarities were associated with supplementation, time (DPP) and the combination of supplementation and DPP. Safflower oil supplementation with C. annuum var. glabriusculum enriched 66 % more its antioxidant value. The comparison of means showed significant differences in the combination of treatments and DPP. The combination of supplemented oil and DPP showed variability in total polyphenol data and ability against ABTS +. An inverse relationship was observed between DPP and total phenolic compounds, and capacity against ABTS +, contrary to the test for DPPH·. The results obtained validate the argument that the addition of piquin chili increases the biofunctionality of safflower oil and can be an alternative source of natural antioxidants.","PeriodicalId":42451,"journal":{"name":"CienciaUat","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2021-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46103892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The importance of this agreement involved the active participation of the Mexican private sector through the “Side Room” a mechanism that functions as a consulting body for negotiation of international agreements. The automotive industry was a sensitive issue due to the integration level of the supply chains and their impact for the North American region. The objective of this research was to analyze the collaboration of the private sector automotive industry in the public consultation processes of the Mexican government for the definition of Mexico’s trade policy during the North American Free Trade Agreement renegotiation period. This is a qualitative research with a descriptive-exploratory scope. Nine semi-structured interviews were carried out with representatives of the Mexican government, experts, or active members of the “Side Room”. The “Side Room” consulting mechanism allowed the Mexican Government to align most of the private sector interests to the country’s trade policy. Although the agreements reached regarding the rules of origin, and the increment on the regional value content of auto parts may require greater participation from the North American macro region, they allow new opportunities for the development of the domestic industry in Mexico. The experience of the Mexican private sector, the negotiation skills and interaction through the “Side Room” and above all, the intense lobbying in the with the private sector, legislators, and governors before and during renegotiation, had a positive impact for the Mexican government in order to satisfactorily conclude the negotiations. The transparency of the public-private consulting process consolidated alliances inside and outside Mexico, albeit with complex challenges.","PeriodicalId":42451,"journal":{"name":"CienciaUat","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2021-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44150381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
