Prioritization of COVID-19 vaccines is one of the most relevant topics in the current pandemic emergency. Prioritization decisions are political decisions that are value-laden, and as such of ethical nature. Despite the clear political and ethical nature of this topic, prioritization decisions are often interpreted and presented as scientific decisions. The aim of this article is twofold. First, we aim to show critical points that characterize certain pandemic vaccination plans from the ethical viewpoint using four dimensions (problem definitions, incorporation of different perspectives, context, and specification). The four dimensions were drawn from findings of the European project "VALIDATE" (VALues In Doing Assessments of healthcare TEchnologies", https://validatehta.eu). Second, we aim to reframe the issue about prioritization itself in the light of the four dimensions mentioned. Our conclusion is that policy-problem definitions, incorporation of different perspectives, contextual considerations and specification of moral principles seem to be common critical points of some vaccination plan documents. The European project "VALIDATE" seems to be able to provide a useful and profitable approach to address many of these critical points.

The Orange Carotenoid Protein (OCP) is a unique water-soluble photoactive protein that plays a critical role in regulating the balance between light harvesting and photoprotective responses in cyanobacteria. The challenge in understanding OCP´s photoactivation mechanism stems from the heterogeneity of the initial configurations of its embedded ketocarotenoid, which in the dark-adapted state can form up to two hydrogen bonds to critical amino acids in the protein's C-terminal domain, and the extremely low quantum yield of primary photoproduct formation. While a series of experiments involving point mutations within these contacts helped us to identify these challenges, they did not resolve them.

Gastric cancer (GC), a prevalent malignancy worldwide, encompasses a multitude of biological processes in its progression. Recently, ferroptosis, a novel mode of cell demise, has become a focal point in cancer research. The microenvironment of gastric cancer is composed of diverse cell populations, yet the specific gene expression profiles and their association with ferroptosis are not well understood.

Stroke is the main cause of disability among neurological diseases. There are questions of the accuracy of topical diagnosis and rehabilitation prognosis in clinical practice. Answers to these questions may be given by an approach to the study of the nervous system as a dynamic network consisting of a set of brain regions with anatomical and functional connections between them.

Background: Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) particularly when coupled with acute respiratory failure (ARF), markedly elevates mortality rates. This investigation focuses on pivotal inflammatory markers in exacerbations of chronic obstructive pulmonary disease (COPD), including the neutrophil-to-lymphocyte ratio (NLR), lactate-to-albumin ratio (LAR), glucose-to-lymphocyte ratio (GLR), prognostic nutritional index (PNI), platelet-to-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII), which are easily determinable from peripheral blood. We aimed to investigate the prognostic value of NLR, LAR, GLR, SII, PNI, and PLR for in-hospital mortality among AECOPD patients with ARF.

Efficiently obtaining atomic-scale thermodynamic parameters characterizing crystallization from solution is key to developing the modeling strategies needed in the quest for digital design strategies for industrial crystallization processes. Based on the thermodynamics of crystal nucleation in confined solutions, we develop a simulation framework to efficiently estimate the solubility and surface tension of organic crystals in solution from a few unbiased molecular dynamics simulations at a reference temperature. We then show that such a result can be extended with minimal computational overhead to capture the solubility curve.
