RESUMO
There is a growing emphasis on seeking stabilizing agents with minimal transformation, prioritizing environmentally friendly alternatives, and actively contributing to the principles of the circular economy. This research aimed to assess the stability of a novel spray-dried hydrocolloid from high Andean algae when introduced into an aqueous solution. Nostoc sphaericum freshwater algae were subject to atomization, resulting in the production of spray-dried hydrocolloid (SDH). Subsequently, suspension solutions of SDH were meticulously prepared at varying pH levels and gelling temperatures. These solutions were then stored for 20 days to facilitate a comprehensive evaluation of their stability in suspension. The assessment involved a multifaceted approach, encompassing rheological analysis, scrutiny of turbidity, sedimentation assessment, ζ-potential, and measurement of particle size. The findings from these observations revealed that SDH exhibits a dilatant behavior when in solution, signifying an increase in with higher shear rate. Furthermore, it demonstrates commendable stability when stored under ambient conditions. SDH is emerging as a potential alternative stabilizer for use in aqueous solutions due to its easy extraction and application.
RESUMO
La pandemia del COVID-19 destaco la importancia y la utilidad de la telemedicina para proporcionar una manera de poner en contacto a pacientes y profesionales de la salud cuando no es posible una consulta en persona en las zonas rurales. Se realizó una revisión sistemática de la Telemedicina y su impacto en la atención médica rural en épocas de COVID-19 desde el 2016 hasta el 2021.La estrategia de búsqueda identificó 1480 artículos de bibliotecas digitales como Google Scholar, ACM Digital Library, ProQuest, ARDI, Taylor & Francis Online, Wiley Online Libray y Microsoft Academic y después de filtrar, se consideraron 71 artículos basados en criterios de exclusión. Los resultados de la revisión sistemática se han centrado en estudios recientes de la Telemedicina donde se resalta la importancia en la atención de los pacientes en zonas rurales también proporciona gráficos estadísticos de los estudios extraídos para comparar por relevancia para sus entornos y situaciones(AU)
The COVID-19 pandemic highlighted the importance and utility of telemedicine in providing a way to connect patients and healthcare professionals when an in-person consultation is not possible in rural areas. A systematic review of Telemedicine and its impact on rural healthcare in times of COVID-19 was carried out from 2016 to 2021. The search strategy identified 1480 papers from digital libraries such as Google Scholar, ACM Digital Library, ProQuest, ARDI, Taylor & Francis Online, Wiley Online Libray and Microsoft Academic. Then 71 papers were considered based on exclusion criteria. The results of the systematic review have focused on recent studies of Telemedicine where it highlights the importance in the care of patients in rural areas also provides statistical graphs of the extracted studies to compare by relevance to their settings and situations(AU)
