Prediction of the structure and mechanical properties of polycaprolactone-silica nanocomposites and the interphase region by molecular dynamics simulations: the effect of PEGylation.

Polymer/silica (PS) nanocomposites are, among numerous combinations of inorganic/organic nanocomposites, one of the most important materials reported in the literature and have been employed in a wide variety of applications. Due to this great interest in the scientific and industry community, knowledge about their physiochemistry allows for a better understanding of their development and improvement. One area of interest found in biopolymers is silica, where silica nanoparticles can be used to increase their mechanical properties and give them higher opportunities to replace synthetic plastics.

Incidence, Clinical Characteristics, Risk Factors and Outcomes of Acute Coronary Syndrome in Patients With COVID-19: Results of the UMC-19-S10.

Background: There is a lack of knowledge about the real incidence of acute coronary syndrome (ACS) in patients with COVID-19, their clinical characteristics, and their prognoses.

Objective: We investigated the incidence, clinical characteristics, risk factors, and outcomes of ACS in patients with COVID-19 in the emergency department.

Methods: We retrospectively reviewed all COVID-19 patients diagnosed with ACS in 62 Spanish emergency departments between March and April 2020 (the first wave of COVID-19).

The impact of Ibero-American science on global bioethical thinking.

The bioethics research conducted in Ibero-American countries has been very much restricted to its own realm. The aim of this study was to perform a bibliometric evaluation of bioethics papers by authors affiliated with Ibero-American institutions, and to determine how their work influences global bioethics literature. We performed a literature search in the Web of Science Core Collection (WoS CC) and Scopus.

The Vatican Opinion on Gender Theory.

Unlabelled: This article is a reasoned response to the article by Timothy F. Murphy, recently published in the prestigious journal , on the supposed opposition between the views of the Catholic Church and what he calls "contemporary science" in relation to certain anthropological issues linked to the gender perspective. To point to "the Vatican" as anchored in an unscientific and anachronistic position, using the term contemporary science to which he attributes a unanimous representation of current scientific thinking on the subject is, in our view, unfounded and completely unacceptable.
