Taxonomic and geographic novelties of Acarnus (Porifera: Demospongiae) from the Brazilian coast, with description of two new species.

Acarnus are poecilosclerid sponges characterized mainly by cladotylote megascleres. Five species are known on the Brazilian coast: Acarnus innominatus Gray 1867, Acarnus radovani (Boury-Esnault, 1973), Acarnus toxeata Boury-Esnault, 1973, Acarnus nicoleae van Soest, Hooper & Hiemstra, 1991 and Acarnus microxeatus Nascimento & Pinheiro, 2023. This study describes two new Brazilian species, Acarnus hooperi sp.

Histomorphometric Study of Non-critical Bone Defect Repair after Implantation of Magnesium-substituted Hydroxyapatite Microspheres.

 The present study aims to analyze histomorphometrically the repair of a non-critical bone defect after implantation of hydroxyapatite (HA) microspheres substituted by magnesium (Mg).  Thirty rats were distributed into 3 experimental groups, evaluated at 15 and 45 days postoperatively: HAG (bone defect filled with HA microspheres); HAMgG (bone defect filled with HA microspheres replaced with 1 mol% Mg), and CG (bone defect without implantation of biomaterials).  After 15 days, the biomaterials filled the entire defect extent, forming a new osteoid matrix between the microspheres.

Exploring depth-related patterns of sponge diversity and abundance in marginal reefs.

Marine sponges play a vital role in the reef's benthic community; however, understanding how their diversity and abundance vary with depth is a major challenge, especially on marginal reefs in areas deeper than 30 m. To help bridge this gap, we used underwater videos at 24 locations between 2- and 62-meter depths on a marginal reef system in the Southwestern Atlantic to investigate the effect of depth on the sponge metacommunity. Specifically, we quantified the abundance, density, and taxonomic composition of sponge communities, and decomposed their gamma () diversity into alpha () and beta () components.

New records of Neopetrosia carbonaria (Lamarck, 1814) from the Brazilian coast reveal new morphological features and spicule types.

Sponges of the family Petrosiidae have usually a stony and brittle texture due the high silica content of the mineral skeleton that is formed by a more-or-less regular isotropic reticulation of undefined primary and secondary tracts. Neopetrosia species are distributed worldwide and twelve species are found in the Tropical Western Atlantic Ocean, of which four are recorded from the Brazilian coast. Here, we describe new Neopetrosia carbonaria specimens from several localities along the NE Brazilian coast, analyze the Neopetrosia carbonaria holotype and review the previous record of N.

Retrospective Investigation in Horses with Encephalitis Reveals Unnoticed Circulation of West Nile Virus in Brazil.

During these past years, several studies have provided serological evidence regarding the circulation of West Nile virus (WNV) in Brazil. Despite some reports, much is still unknown regarding the genomic diversity and transmission dynamics of this virus in the country. Recently, genomic monitoring activities in horses revealed the circulation of WNV in several Brazilian regions.

Systematization of Nursing Care: seeking defining and differentiating theoretical contours.

The objective of this study was to elaborate theoretical propositions to help understanding the Systematization of Nursing Care as a distinct phenomenon of the Nursing Process. It is a reflective, theoretical study that presented two categories: "Systematization of Nursing Care: seeking differentiating contours" and "Systematization of Nursing Care: seeking defining contours". It was identified that the systematization is not concerned with guiding the professional nursing care itself, since this issue, together with the guidelines regarding the elaboration of clinical documentation resulting from the implemented nursing care, is related to the process.

MEWAR: Development of a Cross-Platform Mobile Application and Web Dashboard System for Real-Time Mosquito Surveillance in Northeast Brazil.

Mosquito surveillance is a crucial process for understanding the population dynamics of mosquitoes, as well as implementing interventional programs for controlling and preventing the spread of mosquito-borne diseases. Environmental surveillance agents who performing routine entomological surveys at properties in areas where mosquito-borne diseases are endemic play a critical role in vector surveillance by searching and destroying mosquito hotspots as well as collate information on locations with increased infestation. Currently, the process of recording information on paper-based forms is time-consuming and painstaking due to manual effort.

Implications of Nursing Care Systematization in Brazilian professional practice.

To analyze the implications of the Nursing Care Systematization in Brazilian professional practice. Theoretical and reflective study, which listed as analytical categories the regulatory framework of systematization, the implications for professional practice, the limits and possibilities. In the legal frameworks, an evolution of understanding about Systematization was identified, which resulted in an update in the resolution that deals with the theme.

Electrocorticographic description of the effects of anticonvulsant drugs used to treat lidocaine-induced seizures.

Introduction: Local anesthetics are widely used in clinical practice. While toxicity is rare, these drugs can cause potentially lethal seizures.

Objective: In the present study, we investigated the electrocorticographic (ECoG) and electromyographic patterns of seizures induced by acute lidocaine (LA) toxicity and treated with anticonvulsant drugs.

Alteration of Testosterone Levels Changes Brain Wave Activity Patterns and Induces Aggressive Behavior in Rats.

Testosterone is responsible for several changes in the brain, including behavioral and emotional responses, memory, and cognition. Given this, we investigated changes in the brain wave profile caused by supplementation with exogenous testosterone in both castrated and non-castrated rats. We also investigated the serum testosterone levels, renal and hepatic function, and the lipid and behavioral profiles.

[Factors associated with concentrations of hemoglobin in preschoolers].

This study sought to identify the association between the concentration of hemoglobin and socio-environmental, maternal, biological-nutritional and health condition characteristics in preschool children; as well as the serum concentrations of zinc and retinol. It involved a cross-sectional study with 335 individuals, a representative sample of children enrolled in child day care centers in the city of Campina Grande, Paraíba. In the 294 children studied, the adjusted model showed lower concentrations of hemoglobin when the house was not made of bricks; there was no sewerage system; no public garbage collection; no treatment of drinking water; maternal difficulties for reading, writing and making calculations; age between 9 - 24 months; weight/age < - 2 score Z and health problems in the last 15 days, as well as in cases of lower serum concentrations of zinc and retinol.
