ABSTRACT

Agar is a hydrocolloid found in red seaweeds, which has been of industrial interest over the last century due to its multiple applications in the food, cosmetic, and medical fields. This polysaccharide, extracted by boiling for several hours, is released from the cell wall of red seaweeds. However, the environmental impact coming from the long processing time and the energy required to reach the targeted processing temperature needs to be reduced. In this study, a response surface methodology was employed to optimize both conventional extraction and ultrasound-assisted extractions. Two different models were successfully obtained (R2 = 0.8773 and R2 = 0.7436, respectively). Additionally, a further re-extraction confirmed that more agar could be extracted. Protein was also successfully co-extracted in the seaweed residues. Optimized conditions were obtained for both the extractions and the re-extraction of the two methods (CE: 6 h, 100 °C; and UAE: 1 h, 100% power). Finally, FT-IR characterization demonstrated that the extracts had a similar spectrum to the commercial agar. Compared to commercial samples, the low gel strength of the agar extracts shows that these extracts might have novel and different potential applications.

ABSTRACT

Objetivos: Mejorar la atención sanitaria prestada a los niños y adolescentes con depresión en el ámbito de la atención primaria y especializada. Ofrecer recomendaciones al profesional sanitario para la atención de estos pacientes. Desarrollar indicadores de evaluación de la calidad asistencial. Ayudar a los pacientes y a sus familiares a la toma de decisiones informada y a la mejora de la comunicación entre los pacientes y los profesionales. No se abordan otros servicios, como los sociales, educacionales o de tiempo libre. Aspectos contemplados Las áreas clínicas que contempla la guía son: - Criterios diagnósticos y caracterización de la depresión infanto-juvenil. - Factores de riesgo y de protección. - Evaluación. - Perspectivas de pacientes y familiares. - Cribado en atención primaria. - Opciones de tratamiento de la depresión: - Tratamiento psicológico (modalidades, numero de sesiones, duración). - Manejo farmacológico (indicación, dosis, duración, cese, efectos secundarios, toxicidad y ausencia de respuesta a la medicación). - Tratamiento combinado. - Prevención de recaídas/recurrencia. - Estrategias para la depresión que no responde al tratamiento. - Tratamiento de la depresión mayor con síntomas psicóticos. - Otras alternativas terapéuticas: ejercicio físico, intervenciones online y terapias alternativas. - El consentimiento informado desde el punto de vista legal en España. - Algoritmo terapéutico: criterios de derivación y manejo según gravedad. Aspectos no abordados en la GPC 1) Los trastornos distímico, bipolar, ni el adaptativo. 2) La prevención primaria de la depresión en la infancia y adolescencia. 3) La prevención de la conducta suicida, debido a que este aspecto se recoge en la GPC de Prevención y Tratamiento de la Conducta Suicida del Programa de GPC en el SNS, en su apartado especifico sobre infancia y adolescencia.

ABSTRACT

The aim of the present study was to develop a simple method to measure ranitidine, using 100 microL of plasma, by high-performance liquid chromatography with a Symmetry C(18) column and UV detection at 313 nm. Linearity was assessed in the range from 50 to 1500 ng ml(-1) and had a correlation coefficient of 0.999. The inter- and intra-day coefficients of variation were less than 7%. The limits of detection and quantitation were 5 and 15 ng ml(-1), respectively. Drug levels were determined satisfactorily in three patients. A simple and reliable method was developed which uses a microvolume of plasma, particularly useful in low-weight children.
