Published: August 2022

This study aimed to revalidate an HPLC-based analytical methodology to determine  tacrolimus within lipid-core nanocapsules and to evaluate the quality of such nanosystems. Chromatographic separation was achieved by employing a C18 column as a stationary phase and a ternary mixture of acetonitrile: water: phosphoric acid (700:299:1 v/v) as the mobile phase. The revalidated method proved to be linear in the range of 1-60 µg.mL−1 for tacrolimus (r2 >0.999). Detection and quantification limits were 45.38 ng.mL-1 and 137.51 ng.mL-1, respectively, which assures the methodology sensitivity. The method was also precise (RSD = 1.78% between samples). Besides, the methodology demonstrated accuracy and robustness. The lipid-core nanocapsules-loaded tacrolimus showed exclusively nanosized particles (±190 nm and polydispersity index of ≤v0.2), negative zeta potential (-13.67±1.16), and slightly acidic pH (5.58 ± 0.06), with a content of 98.90±2.32%  and encapsulation rate of 99.23±0.32%.  Tacrolimus-loaded in lipid-core nanocapsules-loaded tacrolimus showed stability for at least 30 days at room temperature and a sustained release profile compared to the drug in solution.

This study aimed to evaluate the influence of the grape seed oil (GSO) on the sun protection factor (SPF) of sunscreen emulsified formulations containing butyl methoxydibenzoylmethane (avobenzone (AVO)) and octyl methoxycinnamate (OMC) developed by phase inversion temperature (PIT) employing a Central Composite Design. Formulations were prepared by PIT emulsification process. Seventeen emulsions containing different amounts of GSO, AVO and OMC were obtained according to experimental design. In vitro SPF was determined using a spectrophotometric method. As expected, formulations with the highest concentrations of UV filters, AVO and OMC, resulted in the highest SPF values, while the lowest SPF values were obtained by formulations containing concentrations of these filters below the central point. In the tested concentrations, the variable OMC and its combination with GSO showed to influence the SPF linearly as a function of their concentrations in formulations. The combination of GSO with OMC contributed to increase in vitro SPF. The use of natural compounds with antioxidant activity, such as GSO, is a viable strategy to increase the effectiveness of sunscreens to protect the human skin against UV-induced damage.

Análisis de la Operación de Paz de Naciones Unidas en Mali: contraterrorismo y contrainsurgencia en MINUSMA
Authors: Bernal Fabra Jordi
Published: August 2022

Este artículo analiza el papel de la Misión Multidimensional Integrada de Estabilización de las Naciones Unidas en Malí (MINUSMA) en la lucha contra el terrorismo y la insurgencia. Esta misión de paz es víctima directa de los ataques terroristas e insurgentes, lo que lleva a preguntarnos si los combate activamente, y a revisar si estas tareas emanan del mandato y su implementación, o si tales amenazas llevan a la MINUSMA a combatirlas como consecuencia. El artículo utiliza los elementos teóricos del contraterrorismo y la contrainsurgencia per se, así como aquellos relacionados con las operaciones de paz. Luego, mediante una metodología de investigación cualitativa, utiliza la MINUSMA como estudio de caso para exponer la evolución de las operaciones de paz y la posible expansión actual y futura de sus tareas. Esto, a través del análisis de las resoluciones del Consejo de Seguridad, la literatura académica y otros documentos de las Naciones Unidas. El estudio concluye que, efectivamente, la MINUSMA ha llevado a cabo tales tareas, directamente y en cooperación con la operación militar francesa. Estas tareas surgen implícitamente del mandato, con una estructura organizativa y operacional al servicio de estas, y se ven reforzadas por factores sobrevenidos sobre el terreno. Este cambio, eventualmente, acaba con su imparcialidad, con lo que aumentan los riesgos de los cascos azules, disminuyen su eficacia y perturban la doctrina de operaciones de paz de las Naciones Unidas. En conclusión, encontramos que el mandato tácito y su vaguedad no solo dificultan el análisis académico, sino también las tareas sobre el terreno y el futuro de la seguridad del personal internacional y la población de Malí y el Sahel.

Published: August 2022

Background and purpose: Information on outcomes after some modern total ankle replacement (TAR) designs is scarce. We therefore examined outcomes after trabecular metal (TM) TAR in Sweden by use of data from the national registry.Patients and methods: On December 31, 2020, 239 primary TM TARs had been reported to the Swedish Ankle Registry. We analyzed prosthesis survival probability, using exchange or permanent extraction of components as endpoint for 239 protheses with mean follow-up of 2.2 years (0.1–6.6), risk of revision, as well as patient-reported outcome measures (SEFAS/EQ-5D/EQ-VAS) and satisfaction with surgery.Results: 7/239 prostheses (3%) had been revised by December 31, 2020. We found an overall prosthesis survival probability of 95% (95% CI 89–98) after 3 years. 2 years after surgery 81% of the answering patients were satisfied or very satisfied with surgery and patients reported median SEFAS 36 (max 48), EQ-5D 0.90 (max 1), and EQ-VAS 80 (max 100).Interpretation: We found short- to mid-term outcomes after TM TAR to be at least as good as after other TAR designs regarding prosthesis survival and patient-reported satisfaction.

This study examined the principal's communication style in encouraging learning effectiveness during the pandemic in junior high school. Previous studies have not explored the principal's communication style in encouraging the effectiveness of online and limited face-to-face learning during the pandemic. This research used a qualitative case study method. The data collection techniques were interviews with one principal, eleven teachers, three education staff, five students, three parents, observation on the learning process, and document data analysis. This research used the six leadership communication styles approach from Tubbs and Moss. The study found that the principal applied the equalitarian, structuring, dynamic, and relinquishing styles. The learning process was adequate to achieve the score and graduating target. Therefore, the learning effectiveness needed improvement because there needs encouraging student activity, improving the teacher's capacities, and encouraging parent participation in the learning process. The principal's communication styles encouraged overcoming barriers due to the lack of online interaction and limited face-to-face learning but did not directly improve the learning effectiveness problem. The principal's communication styles failed to encourage learning effectiveness because the problem was not only communication. The principal was not arranged a particular assessment to solve the learning effectiveness problem.
