Article Synopsis
- The study focuses on the magnetic properties of the "cartwheel" heptanuclear cluster [FeO(OCBu)(Me-dea)(HO)], utilizing Mössbauer spectroscopy and sub-Kelvin magnetization measurements to provide insights into its spin frustration.
- The Fe Mössbauer spectra at temperatures above 150 K revealed a specific ratio of doublets that corresponded to different iron sites within the cluster, confirming a previously proposed spin ground state structure where spins are aligned differently among the central and peripheral sites.
- At sub-Kelvin temperatures, the behavior of the cluster changed, showing spin blocking and single-molecule magnet characteristics, along with a defined anisotropy barrier that allows for quantum tunneling at low temperatures.
Objectives: CONTExT-RA is a cross-sectional, non-interventional multicentre study which enrolled patients diagnosed with RA and receiving DMARD treatment in a secondary care setting. The study evaluated disease control and associated disease burden amongst this Irish population.
Methods: Patients with RA attending six Irish rheumatology centres were invited to participate.
Objective: The main objective of our investigation was to know the incidence and epidemiology of non-tuberculous mycobacteria (NTM) in our area and the prevalence of comorbidities in patients with MNT infection. As secondary objectives, we studied the distribution by species of MNT, the forms of disease and the type of sample used for its diagnosis.
Methods: A retrospective study was carried out in which all the isolates of mycobacteria carried out by the microbiology laboratory of the Hospital Clínico Universitario Lozano Blesa of Zaragoza during the period between January 1, 2011 and December 31, 2018 were included.
Magnetism of Dendrimer-Coated Gold Nanoparticles: A Size and Functionalization Study.

Highly sensitive magnetometry reveals paramagnetism in dendrimer-coated gold nanoparticles. Different types of such nanoparticles, as a result of (i) functionalizing with two distinct Percec-type dendrons, linked to gold via dodecanethiol groups, and (ii) postsynthesis annealing in a solvent-free environment that further promotes their growth have been prepared. Ultimately, for each of the two functionalization configurations, we obtain highly monodisperse and stable nanoparticles of two different sizes, with spherical shape.

The objective is to compare the clinical characteristics and outcome of Latin American and Spanish populations in a cohort of patients hospitalized with COVID-19 during the first year of the pandemic.
Methods: We retrospectively analysed all the Latin American patients (born in South or Central America) hospitalized in our centre from February 2020 to February 2021 and compared them with an age- and gender-matched group of Spanish subjects.
