A meta-analysis of Planarian: an animal model useful to understand the effect of magnetic field Planarian and magnetic field researches

bioRxiv (Cold Spring Harbor Laboratory) (2018)

Liliana Gómez Luna Vivian de la Puente López

Abstract The planarians research since the first description until nowadays has a broad spectrum of topics. The present paper deals on a meta-analysis which identified as a problem the lack of consolidate information and data analysis about the use of planarian as animal model, and specifically the use of magnetic field in regeneration experiments. To conduct the meta-analysis 1255 papers published since 1955 to 2017 were analysed, identifying the Stem cell biology and regeneration as the most published topic, with 276 papers, followed by molecular and cellular analyses (238), genetics (175), inter and transdisciplinary research (107), ecotoxicological evaluations (102), animal model (67), ecological and biological studies (56), magnetic field (57), developmental biology (32) and RNA regulation (31).Other statistics and metrics indicators were taken in to account like total of papers and distribution per year, distribution of paper by journals and selection of main journals according to the number of published papers, most cited papers, authors and countries and distribution of papers by countries. Finally, were analysed those papers with Planarians research using magnetic field, all of them published during the last three years. It was an evidence that this topic is becoming a trending with rising interest, being the most reported species to study the magnetic field effects Dugesia spp. and Girardia sp. Summary statement This work presents a meta-analysis which allows consolidating information and a better understanding of trends in Planarian researches, emphasizing in the use of magnetic field.

Assessment of the Antioxidative Potential of Rosmarinus officinalis L. (Lamiaceae) Irrigated with Static Magnetic Field-Treated Water

Brazilian Archives of Biology and Technology (2020)

Yilan Fung Boix Albys Ferrer Dubois Sophie Hendrix Liliana Gómez Luna Natalie Beenaerts

Phenolic compounds are one of the main groups of secondary metabolites in plants and are known for their antioxidant activity. Rosmarinus officinalis L. (rosemary) contains different phenolic compounds including carnosol, carnosic acid and rosmarinic acid. In Cuba, rosemary cultivation is limited because it is difficult to propagate and has a low yield. As a result, it was removed from the Herbal Medicine National Formulary. However, the National Public Health System has a strong interest in rosemary because of its value as a natural antioxidant medicine. Irrigation with water treated with a static magnetic field (SMF) is a possible strategy to increase rosemary yield. This technology has been applied to accelerate plant growth and increase crop quality. The aim of this study was to evaluate the content of phenolic compounds and antioxidant activity in aqueous leaf extracts from plants irrigated with SMF-treated water in comparison to control plants. Significant differences in phenolic content and antioxidant activity were observed between aqueous extracts of control plants and plants irrigated with SMF-treated water. Therefore, irrigation with SMF-treated water is a promising technology to improve the cultivation of rosemary as a raw material to obtain pharmaceutical products with high antioxidant activities.

Magnetically treated water on phytochemical compounds of Rosmarinus officinalis L.

International Journal of Environment Agriculture and Biotechnology (2018)

Yilan Fung Boix Elizabeth Isaac Alemán Jorge Molina‐Torres Enrique Ramírez Chávez Rosani do Carmo de Oliveira Arruda

Irrigation using water treated with static magnetic field (SMF) has recently been used as a strategy to stimulate the growth and development of different plant species. The aim of this study was to characterize the bioactive compounds and evaluate the anatomical structure of Rosmarinus officinalis L. irrigated with SMF-treated water. Results demonstrate that the treatment promoted plant growth, the number of trichomes and increased concentrations of secondary metabolites. Methanol-extracted leaves revealed that rosmarinic acid was detected in both experimental groups, without a difference in the level. Camphor, α-terpineol and verbenone were determined as the most abundant compounds present in these leaf extracts and were strongly increased in plants irrigated with SMF-treated water. Similar results were also observed for endo-borneol, bornyl acetate and β-amyrin concentrations.Taken together, these results indicate that irrigation with SMF-treated water can be used to improve the production of rosemary to obtain pharmaceutical products with an increased antioxidative activity.

ELEMENTOS CLAVE EN LA IMPLEMENTACIÓN DE SISTEMAS DE GESTIÓN DE LA CALIDAD CON RESPONSABILIDAD SOCIAL EN UNIVERSIDADES DE BAJO DESEMPEÑO

Liliana Gómez Luna Fabiola Santillán Diógenes Díaz Segarra

Los modelos de gestion universitaria dependen no solo de las politicas nacionales, sino de aspectos culturales y del contexto. Si se analiza el modelo de las universidades latinoamericanas, especificamente en Ecuador, parece haber un escenario, donde hay rasgos que responden a patrones del modelo frances y al de universidades publicas britanicas; ademas, de incorporar criterios evaluativos internacionales correspondientes a estandares de ordenamientos como el de SCIMAGO. Esta mezcla de modelos, patrones de autoridad y herramientas de control, han generado en las instituciones publicas del Ecuador conflictos que se expresan en debilidades, que limitan un desempeno organizacional de calidad y/o excelencia. Si bien se promueve a nivel regional la cultura empresarial y especificamente en Ecuador y pese a que el estado destina importantes sumas de dinero al desarrollo academico y cientifico de las universidades publicas, aun existe un limitado o bajo desempeno en muchas instituciones de educacion superior, profundas brechas y barreras para la implementacion de los sistemas de calidad, condicionado por elementos clave como el liderazgo, el empoderamiento, la autoevaluacion, la capacitacion, asi como los las politicas y procesos de gestion de la calidad con responsabilidad social, de comunicacion externa e interna y la innovacion. En este trabajo se presenta una reflexion sobre las universidades publicas ecuatorianas y los elementos clave a considerar en la implementacion de sistemas de gestion de la calidad en universidades de bajo desempeno con responsabilidad social. Palabras clave: educacion superior, calidad con responsabilidad social, empoderamiento, liderazgo, universidades de bajo desempeno, universidades ecuatorianas

First Report on Microcystin-LR Occurrence in Water Reservoirs of Eastern Cuba, and Environmental Trigger Factors

Toxins (2022)

José Carlos Rodríguez Tito Liliana Gómez Luna Wim Noppe Inaudis Álvarez

The factors related to cyanotoxin occurrence and its social impact, with comprehension and risk perception being the most important issues, are not yet completely understood in the Cuban context. The objectives of this research were to determine the risk extension and microcystin-LR levels, and to identify the environmental factors that trigger the toxic cyanobacteria growth and microcystin-LR occurrence in 24 water reservoirs in eastern Cuba. Samplings were performed in the early morning hours, with in situ determination and physicochemical analysis carried out in the laboratory. Microcystin-LR were determined in water and within the cells (intracellular toxins) using UPLC–MS analysis after solid phase extraction. The reservoirs studied were found to be affected by eutrophication, with high levels of TN:TP ratio and phytoplankton cell concentrations, high water temperatures and low transparency, which cause collateral effect such as cyanobacterial bloom and microcystin-LR occurrence. In Hatillo, Chalóns, Parada, Mícara, Baraguá, Cautillo, La Yaya, Guisa and Jaibo reservoirs, concentrations of MC-LR higher than the WHO limits for drinking water (1 µg·L−1), were detected.

Characterization of Nitrogen-Fixing Cyanobacterial Consortia Isolated from the Rhizosphere of Carica papaya

Agronomy (2024)

Yadenis Ortega Díaz Liliana Gómez Luna Yilan Fung Boix Yadira Silveira Font Jorge González Aguilera

Nitrogen-fixing cyanobacterial consortia are an alternative to the indiscriminate use of chemical fertilizers that affect the environment, fix atmospheric nitrogen, and can therefore be used as plant growth promoters, synthesize various substances such as auxins, vitamins, and total proteins, and fix atmospheric biofertilizers and soil conditioners. The present study aimed to obtain and develop, by biotechnological means, two consortia of cyanobacteria isolated from the root and rhizosphere of Carica papaya grown in sandy loam soil. The culture was carried out in Blue Green Medium without modified nitrogen (BG110), with aeration of 0.32 L min−1, at a light intensity of 48.83 μEm−2s−1, and a temperature of 22 ± 2 °C. Two consortia consisting of Nostoc commune, Aphanothece minutissima, Planktothrix sp. (C1), Nostoc commune, Calothrix sp., and Aphanothece minutissima (C2) were isolated and morphologically identified. The effective development of these consortia was verified at the laboratory level by obtaining biomass in dry weight as well as photosynthetic pigments, proteins, carbohydrates, and lipids. Germination parameters were determined in seeds of Cucumis sativus L. var. Market plus treated with the nitrogen-fixing cyanobacteria consortia, obtaining a higher germination percentage (>90%), greater root length (>6 cm), and higher vigour index I (513), II (13.02) for the C2 consortium. This broadens the spectrum of rhizosphere-derived microorganisms with potential as growth biostimulators.
