Emergence of multiple spontaneous coherent subnetworks from a single configuration of human connectome coupled oscillators model.

Multi-state metastability in neuroimaging signals reflects the brain's flexibility to transition between network configurations in response to changing environments or tasks. We modeled these dynamics with a Kuramoto network of 90 nodes oscillating at an intrinsic frequency of 40 Hz, interconnected using human brain structural connectivity strengths and delays. We simulated this model for 30 min to generate multi-state metastability.

Characterization of thrombosis risk in ambulatory patients with cancer: results of the observational, prospective, multicenter CARTAGO study.

Background: Venous thromboembolism (VTE) is one of the leading causes of death in patients with cancer. Currently, there is a need to develop an easily applicable risk model that can identify patients who will benefit from receiving primary thromboprophylaxis to reduce the incidence of VTE.

Patients And Methods: This was a non-interventional, multicenter, observational, prospective study carried out in 62 Oncology and Hematology services in Spain and Portugal between January 2018 and December 2019.

Diffuse Glioneuronal Tumor With Oligodendroglioma-Like Features and Nuclear Clusters Relapse in a Seven-Year-Old Boy: An Unusual Case Exhibiting Near-Tetraploidy and Chromosome 14 Diploidy.

Diffuse glioneuronal tumor with oligodendroglioma-like features and nuclear clusters (DGONC) is a rare brain tumor of the central nervous system (CNS). Although only a few cases of DGONC have been reported following the initial description of the tumor, they have a distinct DNA methylation pattern and share a recurrent chromosomal finding of monosomy 14. We encountered a seven-year-old boy who presented with seizures and was found to have a left frontal and suprasellar mass.

The Rise of Mpox in a Post-Smallpox World.

Reports of mpox are rising in Africa where the disease is endemic and in new countries where the disease has not been previously seen. The 2022 global outbreak of clade II mpox and an ongoing outbreak of the more lethal clade I mpox highlight the pandemic potential for monkeypox virus. Waning population immunity after the cessation of routine immunization for smallpox plays a key role in the changing epidemiologic patterns of mpox.

Computational evaluation of the oxidation of superoxide to molecular dioxygen mediated by NNNN-tetradentate copper complexes.

Free radicals such as superoxide are reactive species that, upon accumulation, lead to oxidative stress. The superoxide dismutase (SOD) enzyme mitigates this stress by converting superoxide into hydrogen peroxide and oxygen. However, the probable lack of SOD supplementation has driven the search for alternatives, with copper complexes emerging as promising candidates.
