SSVEP modulation via non-volitional neurofeedback: anproof of concept.

Neuronal oscillatory patterns are believed to underpin multiple cognitive mechanisms. Accordingly, compromised oscillatory dynamics were shown to be associated with neuropsychiatric conditions. Therefore, the possibility of modulating, or controlling, oscillatory components of brain activity as a therapeutic approach has emerged.

Cystic Lesions and Odontogenic Tumors in Older People: A Brazilian Multicenter Study.

Background: Some odontogenic cysts (OCs) and odontogenic tumors (OTs) are infiltrative and often recur, causing bone destruction and tooth loss. In the elderly, in particular, these injuries cause significant morbidity, making rehabilitation difficult and compromising the quality of life of these individuals. Objective: To determine the prevalence and demographic characteristics of OCs, non-odontogenic cysts (NOCs), and OTs diagnosed in an elderly Brazilian population (≥60 years).

Unraveling the protective genetic architecture of COVID-19 in the Brazilian Amazon.

Despite all the efforts acquired in four years of the COVID-19 pandemic, the path to a full understanding of the biological mechanisms involved in this disease remains complex. This is partly due to a combination of factors, including the inherent characteristics of the infection, socio-environmental elements, and the variations observed within both the viral and the human genomes. Thus, this study aimed to investigate the correlation between genetic host factors and the severity of COVID-19.

Acute impact of autoregulation of applied blood flow restriction pressures on bilateral single-joint upper limb resistance exercise.

To investigate the acute effects of 4 sets of autoregulated (AR-BFR) versus non-autoregulated (NAR-BFR) applied pressures during blood flow restriction (BFR) resistance exercise to volitional failure compared with low-load exercise without BFR. A randomized crossover design study was conducted on 32 healthy adults (20.8 ± 2.

Effect of transcranial direct current stimulation on tinnitus modulation: A randomized, double-blind, and placebo-controlled clinical trial: Effect of tDCS on tinnitus modulation: A clinical trial.

Objectives: To evaluate the short and long-term effects of anodal tDCS (a-tDCS) targeting the left temporoparietal area (LTA) on tinnitus severity, annoyance, and loudness.

Methods: This is a double-blind, randomized, sham-controlled, and parallel-group clinical trial. A total of 42 individuals with tinnitus were randomized to a-tDCS (n = 24) or sham tDCS (n = 18).

Protective Effects of Annona Atemoya Extracts on Inflammation, Oxidative Stress, and Renal Function in Cadmium-Induced Nephrotoxicity in Wistar Rats.

Background: Cadmium (Cd), a highly toxic heavy metal from agricultural activities, and its exposure can lead to impaired renal function by increasing reactive oxygen species. The atemoya fruit is known for its high phenolic and antioxidant compounds. This study aimed to evaluate the effects of atemoya extracts on renal function, oxidative stress parameters, and inflammatory biomarkers in a cadmium-induced nephrotoxicity model.

Massive Education in Prison Health in Brazil: A Look Beyond the Walls.

Equal access to health initiatives and services under the principles of universal and comprehensive care remains a challenge in Brazil. The realization of public health policies is further intricate when one examines the health situation of people deprived of liberty. This study showcases the "Prison System: Beyond the Walls" educational pathway, available on the Virtual Learning Environment of the Brazilian National Health System (AVASUS).

Association between molar incisor hypomineralisation and tooth agenesis: a cross-sectional study in Brazilian children and adolescents.

Purpose: The aim of the present was to assess the association between MIH and tooth agenesis (TA) in orthodontic patients from the Federal University of Rio Grande do Norte, Natal, Brazil.

Methods: A cross-sectional study was performed to evaluate the presence of MIH and TA in a sample of 371 pretreatment orthodontic records from patients aged 9-18 years. Statistical analyses were performed using the Chi-square and Fisher's exact tests, and logistic regressions.

Assessment of severity and avoidability of adverse drug reactions in neonates: a reproducibility study of the Hartwig tool and LAAT.

Objective: Tools for classifying adverse drug reactions (ADRs) have not yet been validated in the context of the neonatal intensive care unit (NICU). The study aims to investigate the inter-rater reliability of the Hartwig tool and the Liverpool avoidability assessment tool (LAAT) in assessing the severity and avoidability of ADR cases in hospitalized neonates.

Methods: An observational and prospective study was conducted in the NICU of a maternity hospital in Natal, Brazil.

Local potential energy density - A DFT analysis and the local binding energy in complexes with multiple interactions.

A recently developed method, so-called local potential energy density, LPED, provides the binding energy density of intra/intermolecular interactions. The LPED cannot directly give the binding energy of intra/intermolecular interactions. However, it can indirectly give the binding energy through the linear equation between LPED and supramolecular binding energy, SME.

Familial partial lipodystrophy resulting from loss-of-function PPARγ pathogenic variants: phenotypic, clinical, and genetic features.

The gene encodes a member of a nuclear receptor superfamily known as peroxisome proliferator-activated gamma (PPARγ). PPARγ plays an essential role in adipogenesis, stimulating the differentiation of preadipocytes into adipocytes. Loss-of-function pathogenic variants in reduce the activity of the PPARγ receptor and can lead to severe metabolic consequences associated with familial partial lipodystrophy type 3 (FPLD3).

Improving the Performance of the Layered Nickel Manganese Oxide Cathode of Sodium-Ion Batteries by Direct Coating with Sodium Niobium Oxide.

This research highlights the efficacy of NaNbO as a coating for P2-NaNiMnO cathodes in sodium-ion batteries. The coating enhances the kinetic behavior and cyclability of the electrochemical cells, as shown by electrochemical measurements. XRD analysis indicates that Nb does not incorporate into the cathode structure, implying a physical interaction between the coating and the cathode material.

Kappa-opioid receptor blockade in the inferior colliculus of prey threatened by pit vipers decreases anxiety and panic-like behaviour.

The dorsal midbrain comprises dorsal columns of the periaqueductal grey matter and corpora quadrigemina. These structures are rich in beta-endorphinergic and leu-enkephalinergic neurons and receive GABAergic inputs from substantia nigra pars reticulata. Although the inferior colliculus (IC) is mainly involved in the acoustic pathways, the electrical and chemical stimulation of central and pericentral nuclei of the IC elicits a vigorous defensive behaviour.

Nephroprotective effects of hyperbaric oxygen therapy in murine models of acute kidney injury: A systematic review and meta-analysis.

Aims: Acute kidney injury (AKI) is a life-threatening condition marked by sudden kidney function loss and azotemia. While its management is limited to supportive care, the effects of hyperbaric oxygen therapy (HBO) on AKI remain a subject of conflicting animal research. This study aimed to systematically review and meta-analyze HBO's effects on renal function biomarkers serum creatinine (SCr) and blood urea nitrogen (BUN) in murine AKI models, also exploring tissue-level nephroprotection.
