“…Esto apoya, al menos de manera indirecta, que las secreciones mucosas podrían estar limitando el establecimiento de coliformes en estos peces, y podría ser un elemento regulador de las poblaciones, al menos de E. coli. De la misma manera, el musgo que crece sobre las paredes de los estanques podría tener un efecto bactericida como se ha reportado en varios estudios (Khazigaleeva et al, 2017;Savaroğlu et al, 2011). Por último, el sedimento que se acumula en el fondo de los estanques podría funcionar como una "trampa de bacterias" y disminuir su abundancia en el agua.…”

“…La contaminación por bacterias se da desde aguas arriba de donde se localiza el proyecto TRCR, y contrario a lo que esperábamos, la cantidad de E. coli es menor en el agua que sale directamente de proyecto. Esto hace suponer que la mucosidad u otras sustancias que producen las truchas, o el musgo que crece sobre las paredes de los estanques podría regular la población de E. coli (Dash et al, 2018;Khazigaleeva et al, 2017;Savaroğlu et al, 2011;Subramanian et al 2007;Subramanian et al, 2008). Este hallazgo no excluye la posibilidad de que se produzca una mayor contaminación, por ejemplo, de residuos sólidos o algunos compuestos químicos (e.g., nitrato de amonio; Sidoruk, 2019).…”

Introducción: El Desarrollo de la acuacultura de truchas se ha incrementado gradualmente en las tierras altas de Costa Rica. Como resultado de esta actividad las aguas residuales son descartadas, sin ningún tratamiento previo, directamente en los ríos. Como consecuencia de esta práctica, la actividad truchícola puede contaminar severamente el agua de los ríos con bacterias que pueden afectar la salud humana. Objetivo: El objetivo de este estudio es evaluar la contaminación bacteriana causada por las aguas residuales que se producen como resultado de la actividad truchícola en la cuenca alta de río Savegre. Métodos: Se determinó el Número Más Probable de bacterias coliformes totales y Escherichia coli /100 mL a partir de muestras de agua obtenidas mensualmente (2015-2018) en tres secciones diferentes en el proyecto de acuacultura más grande en la cuenca alta del río. Recolectamos las muestras en la entrada de los estanques para las truchas, a la salida, y 200 m hacia debajo de la salida. Comparamos en número de bacterias entre las tres secciones y entre años de muestreo. Resultados: Se encontró menos coliformes total y E. coli en el agua recolectada justo en la salida del agua de los estanques para truchas. El número de coliformes totales fue mayor en el 2016 y 2017, y el de E. coli en el 2016. Conclusiones: El número de coliformes total y de E. coli es muy alto en el río, pero contrario a lo esperado su número disminuye en el agua residual descartada de los estanques. La contaminación del río es probablemente causada por el agua producida por otras actividades humanas y otros proyectos de acuacultura que se descartada directamente al rio. Podría ser que el mucus producido por las truchas o sustancias liberadas del musgo que cubre la pared de los estanques actúe como agente regulador del crecimiento de las poblaciones de bacterias, como ha sido sugerido en otros estudios. Objective: The objective of this study is to evaluate the bacteria contamination caused by the residual water from the trout aquacultural activity discarded directly on the upper drainage basin of the Río Savegre. Methods: We counted the number of total coliforms and Escherichia coli from samples obtained monthly (2015-2018) at 3 sections of the largest aquacultural development in the upper drainage of the river. We collected samples at the entrance of the fish ponds, at the exit, and 200 m downwards. We compared the bacteria counts among locations and sampling years. Results: We found fewer total coliforms and E. coli in the water collected just at the exit of the fish ponds. We counted more total coliforms in 2016 and 2017, and more E. coli in 2016. Conclusions: The number of total coliforms and E. coli is very high in the river, but unexpectedly their number decreased in the water discarded from the fish tanks. The contamination of the river is likely caused by the water produced by other human activities and other aquaculture developments that discard the residual water directly on the river. We speculate the mucus produced by the trouts or substances released by the moss that cover the wall of fish tanks could regulate the growth of bacteria populations as has been suggested in other studies.

“…It is crucial to realize that the variation in the size of inhibition zones among different extracts may be attributed to the polarity of the compounds obtained. This is because a diffusible but less efficient extract may yield a larger diameter of inhibition compared to a non-diffusible but more potent extract (Savaroglu et al, 2011). Despite of these findings, the crude extracts bioactivities of tested samples may be qualitatively not quantitatively.…”

In this study, three algae (Corallina officillica, Ulva lactuca, and Pterocaldia capallicia) and three aromatic herbs (Ocimum basilicum, Mentha longifoila, and Salvia officinalis) were investigated. Phytochemicals, P. capallicia had the highest total carbohydrate content (17.50%), while M. longifoila had the highest total proteins ratio (17.95%). Mentha longifoila possessed the maximum total lipids percent (32.14%), while C. officillica had the highest ash content (58.83%). As well as, M. longifoila had the highest phenolics and carotenoids values, while U. lactuca had the highest total flavonoids. To antioxidant activity estimated, the S. officinalis (M6) extract showed the highest scavenging activity (89.88%). Regarding antibacterial activities, the C. officillica extract exhibited the most powerful activity against P. aeruginosa ATCC 9027 (44 mm), followed by S. officinalis extract against the same bacterium (40 mm). The GC-MS assessment revealed the existence of several bioactive constituents, involving fatty acids, terpenoids, steroids, flavonoids, carotenoids, phenolic compounds, and other compounds.

“…Subsequently, Spjut et al 1986 [15] summarised the results of the first comprehensive study by NCI on the antitumour properties of extracts from 123 mosses, 13 liverworts, and 1 hornwort species, and reported that 75 species showed varying degrees of cytotoxicity against P388 lymphocytic leukaemia cells. From that time onwards, numerous studies have found that mosses [16][17][18][19][20][21][22][23][24][25][26] and crude liverwort extracts [25,[27][28][29] are cytotoxic for several cancer cell lines (Tables 1 and 2). The molecules responsible for the antiproliferative activity have been identified as terpenoids, bibenzyls, and macrocyclic (bis)bibenzyls, which are reported by various studies as cytotoxic for a wide range of cancer cells (Tables 1 and 2).…”

Bryophytes are a poorly studied group of land plants that have been used in traditional medicine as a multipurpose remedy for centuries. Due to their peculiar morphology and physiology, bryophytes synthesise a multitude of secondary metabolites with a wide range of nutraceutical and pharmaceutical activities. Research has highlighted that secondary metabolites in bryophytes can also act as antitumour agents. Several studies have shown that bryophyte extracts and pure metabolites are cytotoxic against many cancer cell lines. Interestingly, some of these molecules and their derivatives are capable of acting on a specific target in cancer cells. Some macrocyclic(bis)bibenzyls from bryophytes can inhibit P-glycoprotein, reverting multidrug resistant cancer cell phenotypes, induce depolymerization of tubulin, stimulate apoptotic pathways, and inhibit angiogenesis. This brief review aims to collect recent knowledge on secondary metabolites of bryophytes and their derivatives, which have demonstrated an interaction with different molecular processes in cancer cells.
