Understanding the solubility dynamics of elements during wet deposition is crucial for assessing their environmental impacts. In this study, we investigated the solubility behaviour of various elements originating from natural and anthropogenic sources using a dataset of 106 samples describing the sequential collections of 8 rainfall events. Our results reveal distinct solubility patterns depending on the type of event, with mineral-dust events exhibiting lower solubility and anthropogenic events displaying higher solubility, in relation with dust content and pH.

Purpose: Over the past 15 years, the landscape of early phase clinical trials (EPCTs) has undergone a remarkable expansion in both quantity and intricacy. The proliferation of sites, trials, sponsors, and contract research organizations has surged exponentially, marking a significant shift in research conduct. However, EPCT operations suffer from numerous inefficiencies, such as cumbersome start-up processes, which are particularly critical when drug safety and the recommended phase II dose need to be established in a timely manner.

Revising the null model in language evolution research.

Behav Brain Sci

January 2025

Department of Experimental Linguistics, Centre for Language Evolution Studies, Nicolaus Copernicus University in Toruń, Toruń,

We comment on the consequences of the target article for language evolution research. We propose that the default assumption should be that of language-readiness in extinct hominins, and the integration of different types of available evidence from multiple disciplines should be used to assess the likely extent of the realization of this readiness. The role of archaeological evidence should be reconsidered.

Predictive modelling of acute Promyelocytic leukaemia resistance to retinoic acid therapy.

Brief Bioinform

November 2024

Department of Biology, École Normale Supérieure, 46 rue d'Ulm, 75005 Paris, France.

Acute Promyelocytic Leukaemia (APL) arises from an aberrant chromosomal translocation involving the Retinoic Acid Receptor Alpha (RARA) gene, predominantly with the Promyelocytic Leukaemia (PML) or Promyelocytic Leukaemia Zinc Finger (PLZF) genes. The resulting oncoproteins block the haematopoietic differentiation program promoting aberrant proliferative promyelocytes. Retinoic Acid (RA) therapy is successful in most of the PML::RARA patients, while PLZF::RARA patients frequently become resistant and relapse.
