Exploring structural, magnetic, and catalytic diversity in tetranuclear {CuO} cubane cores and a dinuclear complex derived from closely related ligand systems.

The coordination compounds featuring a {CuO} core, typically bridged by hydroxo or alkoxo groups, are particularly intriguing due to their notable magnetic properties and catalytic activity. In this study, we explored the synthesis and characterization of four new Schiff base ligands and their subsequent complexation with Cu salts, which resulted in the formation of three tetranuclear complexes: [Cu(L)]·2HO (1), [Cu(L)(HL)](Cl)(NO)·5HO (2), and [Cu(L)] (3), as well as one dinuclear complex: [Cu(L)] (4). These tetranuclear complexes all feature a {CuO} core, but with differing coordination environments around the Cu centers.

Sustainable Carbon Dots Loaded into Carboxymethylcellulose Based Hydrogels for Uterine Cancer Bioimaging.

: The development of innovative materials for disease diagnostics and therapeutics is a fast-growing area of scientific research. In this work, we report the development of innovative hydrogels incorporating carbon dots (Cdots) for bioimaging purposes. : The Cdots were prepared using a sustainable and low-cost process, starting with an underused fiber from the Brazilian semiarid region.

Clinical characteristics of the Ala21Val variant in the myelin proteolipid protein 1 (PLP1) gene associated with Pelizaeus-Merzbacher disease in a Brazilian male patient.

Here, we report the case of a 29-year-old male with classic Pelizaeus-Merzbacher disease (PMD) harboring the PLP1 variant NM_000533.5:c.62 C > T, leading to an NP_000524.

Intralesional bleomycin sclerotherapy for head and neck low-flow vascular malformations - A retrospective single-center experience.

Low-flow vascular malformations (LFVMs) account for over 90% of all vascular malformations, with the highest prevalence in the head and neck region. Intralesional sclerotherapy is the treatment of choice for subcutaneous LFVMs, although there is no consensus on optimal agent selection or dosage. Mild sclerosing agents, such as bleomycin, are commonly used in sensitive anatomical areas, including the head and neck, due to their favorable safety profile, despite slightly lower efficacy.

Phylogenetic inferences reveal multiple intra- and interhost genetic diversity among bat rabies viruses circulating in northeastern Brazil.

Background: Rabies, a lethal viral zoonotic disease, remains a significant global public health concern. In northeastern Brazil, in particular, its epidemiology is complex and dynamic, characterized by the presence of several reservoirs associated with human rabies infection.

Methods: This study, conducted from June 2022 to July 2023, was part of a passive epidemiological surveillance initiative under Brazil's National Rabies Surveillance Program.
