We present a novel two-dimensional (2D) boron nitride allotrope, Irida- (Ir-BN), analogous to the all-carbon Irida-Graphene (Ir-G). The predicted structure of Ir-BN consists of alternating boron and nitrogen atoms, forming three distinct lattices with 3-, 6-, and 8-membered ring patterns. First-principles calculations based on density functional theory (DFT) formalism and ab initio molecular dynamics (AIMD) simulations were performed to investigate its structural, mechanical, electronic, and optical properties.

Background: A wide range of liquid embolic agents has been used in endovascular treatment (EVT) of dural arteriovenous fistulas (dAVFs) and cerebral arteriovenous malformations (cAVMs). Newer liquid embolics, Squid (Balt) and PHIL (MicroVention), aim to improve the safety and efficacy of EVT of dAVFs and cAVMs.
Objective: To assess the safety and efficacy of EVT of cAVMs and dAVFs using Squid or PHIL as an embolic agent.

Population aging generated changes in the epidemiological profile and culminated in a high frequency of diseases. The objective of this study was estimating the prevalence of multimorbidity and the associated variables in the elderly of an educational program in the Federal District of Brazil. This is a cross-sectional study with data collection carried out during the period from December 2022 to April 2023 by means of telephone calls.

The aim of the present study was to propose an explanatory model on the influence of religiosity on the subjective well-being of lesbians, gays, and bisexuals (LGB), testing internalized homonegativity as a mediator variable and LGB and religious identities' integration as a moderator variable. The study included 409 cisgender Brazilian religious LGBs. The findings show that for individuals without integrated LGB and religious identities, there is both a positive direct effect of religiosity on the subjective well-being and an indirect negative effect mediated by internalized homonegativity, so that higher levels of religiosity lead to higher levels of internalized homonegativity, which, in turn, leads to a reduction of levels of subjective well-being.

We have synthesized and characterized a novel series of ruthenium complexes with formulas [RuCl(N-S)(dppm)]PF (Ru1), [Ru(N-S)(dppm)]PF (Ru2), [Ru(N-S)(dppe)]PF (Ru3), [Ru(N-S)(dppen)]PF (Ru4), [Ru(N-S)(bpy)]PF (Ru5). In these formulas, N-S or S represents H2mq (2-mercapto-4(3)-quinazoline); dppe (1,2'-bis(diphenylphosphine)ethane), dppm (1,1'-bis(diphenylphosphine)methane), or dppen (1,2'-bis(diphenylphosphine)ethene); and bpy refers to 2,2'-bipyridine. We have also compared the cytotoxicity of cisplatin with these ruthenium complexes to murine melanoma cells (B16-F10), human melanoma cells (A-375), and the non-tumoral human keratinocyte cell line (HaCat).

Aim: To analyze the association between Primary Health Care (PHC) performance and institutional ability to provide care for individuals with noncommunicable diseases (NCDs).
Methods: Cross-sectional study conducted with primary care nurses and physicians in Brazil. The performance of PHC was assessed by using the Primary Care Assessment Tool (PCAT), whereas institutional ability for the care of people with NCDs was assessed through the Assessment of Chronic Illness Care (ACIC).

Despite recent progress, bacterial degradation of lignin is not completely understood. To address the mechanisms that bacteria from unknown taxonomic groups use to perform lignin-monomer degradation, functional analysis of bacterial metagenome-assembled genomes from soil-derived consortia enriched for microorganisms capable of degrading lignin was performed. A total of 232 metagenome-assembled genomes were recovered.

Seaweeds are natural sources of sulfated polysaccharides (SPs), biopolymers with remarkable pharmacological properties, including biological actions capable of attenuating components of the inflammatory process such as edema, cytokines, cell migration and pain. Our results confirm that SPs obtained from Gracilaria domingensis (SP-GD) are agarans, primarily composed of residues of β-d-galactopyranose 6-sulfate and 3,6-anhydro-α-l-galactopyranose. Specifically, SP-GD at a dose of 10 mg/kg was effective in significantly reducing paw edema induced by carrageenan or histamine, serotonin, bradykinin, 48/80 and prostaglandin E2.

A free-ranging capuchin monkey developed a synchronous biphasic pleural and peritoneal mesothelioma, a rare form of this tumor. Exophytic nodules were dispersed over the serosal surfaces, showing marked microscopical malignant features composed of both epithelioid and spindeloid neoplastic cells immunopositive for Pan-Cytokeratin, Cytokeratin 5/6, Vimentin, WT-1, and D2-40.

Immunological memory, a fundamental immune system mechanism, is instrumental in long-term protection. Successful vaccines can elicit and sustain immunological memory against pathogens for the long term. Memory B cells (MBC) are key players in secondary responses due to their longevity and rapid differentiation into high-affinity antibody-secreting cells upon second antigen exposure.

Carbon dots (CDs) are zero-dimensional carbon nanomaterials that have been subject of considerable interest due to their remarkable electronic and optical characteristics. Their adjustable properties have gathered attention in different fields, including biological sensing, drug delivery, photodynamic therapy, photocatalysis, solar cells, and latent fingerprint development. In forensic science, the frequently reported outstanding photoluminescence behavior and biocompatibility of CDs are particularly important.

In Brazil, the health emergency unleashed by the Covid-19 pandemic must be understood in the context of the government administration of the former president, Jair Bolsonaro. The new coronavirus was turned into a war machine, something already seen in other moments of the history of indigenous peoples, when epidemics were strategically used to promote indigenous genocide and usurp their territories. The Sanöma, a subgroup of the Yanomami language family, assert that Covid-19 did not leave individualized traces of 'sequelae' but made itself felt in the deaths that could not undergo the traditional funeral rites due to the sanitary measures, generating a cosmological and existential tension for the collective as a whole.

Geopolitical determinants of health have been well recognized by the World Health Organization and are increasingly being discussed across governments, institutions, academics, policy makers, and across global health sector. Geopolitical determinants of health are events, structures, processes, and factors that influence individual health including mental health, public and population mental health both directly and indirectly. Consequently, nation's responses to these factors will affect short-term and long-term health outcomes.
