Factors associated with menstrual-related disturbances following SARS-CoV-2 vaccination: a Spanish retrospective observational study in formerly menstruating women.

Background: A growing body of evidence suggests a potential link between the SARS-CoV-2 vaccine and menstrual changes in women who were menstruating at the time of vaccination. Nevertheless, the prevalence of this event in those with secondary amenorrhea for different causes, i.e.

Low-coordinate bis-phosphine and monophosphine Ni(0) complexes: synthesis and reactivity in C-S cross-coupling.

Preformed Ni(0) complexes are rarely used as precatalysts in cross-coupling reactions, although they can incorporate catalytically active nickel directly into the reaction. In this work, we focus on the preparation and the catalytic application of low-coordinate Ni(0) complexes supported by bulky monophosphine ligands in C-S cross-coupling reactions. We have prepared two families of Ni(0) complexes, bis-phosphine aducts of the type [Ni(PRAr')] (Ar' = -terphenyl group) and monophosphine derivatives of the type [Ni(PRAr')(DVDS)] (DVDS = divinyltetramethyldisiloxane).

Phylosymbiosis and Elevated Cancer Risk in Genetically Depauperate Channel Island Foxes.

Examination of the host-associated microbiome in wildlife can provide critical insights into the eco-evolutionary factors driving species diversification and response to disease. This is particularly relevant for isolated populations lacking genomic variation, a phenomenon that is increasingly common as human activities create habitat 'islands' for wildlife. Here, we characterised the gut and otic microbial communities of one such species: Channel Island foxes (Urocyon littoralis).

Increasing Hispanic Participation in Cognitive Research: An Examination of a Decade of Web-Based Recruitment into MindCrowd.

The research community has struggled to successfully recruit and retain Hispanic participants into research studies. The purpose of our study is to describe Hispanic enrollment into our study across the past decade. We sought to identify trends in Hispanic engagement in internet-based recruitment over three distinct time periods including the COVID-19 pandemic.
