The potential of stem cell (SC) therapies for eye diseases is well-recognized. However, the results remain only encouraging as little is known about the mechanisms responsible for eye renewal, regeneration and/or repair. Therefore, it is critical to gain knowledge about the specific tissue environment (niches) where the stem/progenitor cells reside in eye. A new type of interstitial cell-telocy...

The incidence of placenta previa is 0.2-0.9% but continues to be one the most serious factors in development obstetric’s bleeding and perinatal losses. situation aggravated by fact that combined with various variations abnormal (deep) attachment uterus (placenta adhaerens, accreta, increta, percreta). Placenta previa, vasa cause significant maternal morbidity mortality. With increasing both ces...

Knowledge about the diversity and spatiotemporal variability of epiphytic diatom communities in estuarine meadows has great relevance for coastal ecology and, thus, contributes to understanding impact natural anthropogenic changes on seagrass meadows. The community diatoms Ruppia maritima L. was investigated two environments with different levels nutrient loads. Both impacted non-impacted had s...

Las arvenses juegan un papel importante en el desarrollo y producción de los cultivos al competir por agua, nutrientes del suelo luz, además ser reservorio patógenos e insectos plaga. El objetivo este estudio fue identificar plantas nativas exóticas dentro parcelas chile Jalapeño (Capsicum annuum L.) para diseñar futuras estrategias manejo. Durante mayo a julio 2019 2021 se realizaron recolecta...

The release of intercellular contacts in MDBK cells, initiated by the depletion of Ca 2+ ions from the culture medium, results in the endocytotic uptake of membrane vesicles containing specific membrane constituents of the zonula adhaerens (ZA). During this process the junction-derived, endocytosed vesicles remain associated with the ZA plaque components, while the plaque and its attached actin...
