A huge challenge after the emergence of COVID-19 has been the discovery of effective antiviral drugs. Although remdesivir (RDV) emerged as one of the most promising drugs, its pharmaceutical formulation Veklury® is limited by moderate efficacy, high toxicity and need for parenteral administration. The aim of the present work was to develop a liposomal formulation of RDV for pulmonary administration and evaluate its efficacy in models of COVID-19.

Objective: To carry out a situational analysis of the medication practices in Brazilian hospitals through the Medication Safety Self-Assessment for Hospitals and the factors associated with better performance in the evaluation.

Methods: This is a multicenter cross-sectional study in which the results of the application of the Medication Safety Self-Assessment for Hospitals, between 2015 and 2020, in 30 Brazilian hospitals were described. In addition, whether the institutional profile was associated with higher self-assessment scores (better performance in the evaluation) was also evaluated.

Nowadays, experimental research advances in condensed matter physics are deep-rooted in the development and manipulation of nanomaterials, making it essential to explore the fundamental properties of materials that are candidates for nanotechnology. In this work, we study the dependence of the molybdenum disulfide (MoS2) Raman modes on the sample temperature and on the excitation laser power. From the correlation between these two sets of measurements, we determine the planar thermal conductivity of MoSmonolayers, bilayers, trilayers, four layers, seven layers, and eight layers.

Sea turtles are highly migratory and predominantly inhabit oceanic environments, which poses significant challenges to the study of their life cycles. Research has traditionally focused on nesting females, utilizing nest counts and mark-recapture methods, while male behavior remains understudied. To address this gap, previous studies have analyzed the genotypes of females and hatchlings to indirectly infer male genotypes and evaluate the extent of multiple paternity within populations.
