Minimally invasive Ponto surgery (MIPS) enables the installation of percutaneous bone-anchored hearing implants (BAHIs) with a drill guide through a hole punch incision. Despite being well established for adults, there is a lack of studies in the literature regarding its use in pediatric patients. The aim of the present study was to investigate the hearing performance and soft-tissue outcomes of the use of MIPS under local anesthesia in children with unilateral craniofacial malformation (UCM).

The purpose of this experiment was to explore whether simultaneous access to consequences configures a defining functional feature of coordination. We evaluated whether coordination episodes are maintained when reinforcers are alternately presented to two cooperating rats across these episodes, in contrast to the delivery of reinforcers simultaneously for both rats and independently for each rat. Rat pairs responded under either a tandem fixed-interval (FI) 10-s FI 10-s or a tandem variable-interval (VI) 10-s VI 10-s schedules.

Introduction: Rural communities continue to struggle to access quality healthcare services. Even in countries where the majority of the population live in rural and remote areas, resources are concentrated in big cities, and this is continuing. As a result, countries with the highest proportion of rural residents correlate with the poorest access, which has negative implications for the health and wellbeing of people.

Malachite Green (MG) is an antibiotic with antifungal activity, which is illegal to use in agriculture due to its mutagenic and teratogenic properties. Several scientific papers have been published on MG in fish. Therefore, an attempt was made to determine the meta-analysis concentration of MG in fish based on countries and types of fish subgroups, as well as the health risks of consumers, using the Monte Carlo simulation (MCS) model.

Background: Urban arboviruses pose a significant global burden, particularly in tropical regions like Brazil. São Sebastião, a lower-middle-class urban area just 26 km from the Brazilian capital, is an endemic area for dengue. However, asymptomatic cases may obscure the actual extent of the disease.

The prophylactic HPV vaccines are known to prevent HPV infections and HPV-associated disease, although there is evidence of reduced response to the HPV vaccination among individuals living with HIV. Prior studies among individuals without HIV suggest that a single HPV vaccine dose induces humoral immune responses that, while lower than those induced by two or three doses, still confer protection against HPV infection.

Background: The development of superior summer maize hybrids with high-yield potential and essential agronomic traits, such as resistance to lodging, is crucial for ensuring the sustainability of maize cultivation. However, the task of identifying and breeding genotypes that exhibit exceptional performance and stability across multiple environment conditions, while considering a wide range of traits, is challenging. Given the backdrop of global climate change, understanding which climate variables and soil properties most significantly impact environmental similarity is essential for selecting hybrids with improved adaptability to regions with diverse climatic and soil conditions.

Background: Diazotrophs carry out biological nitrogen fixation (BNF) using the nitrogenase enzyme complex (NEC), which relies on nitrogenase encoded by nif genes. Horizontal gene transfer (HGT) and gene duplications have created significant diversity among these genes, making it challenging to identify potential diazotrophs. Previous studies have established a minimal set of Nif proteins, known as the Nif core, which includes NifH, NifD, NifK, NifE, NifN, and NifB.

Background: Considering that peripheral blood biomarkers are prognostic predictors for several human tumors, this study aimed to comparatively analyze the association of hematological alterations with the incidence of epithelial dysplasia (ED) and oral squamous cell carcinoma (OSCC) in male and female mice treated with 4-nitroquinoline-N-oxide (4NQO) and ethanol (EtOH).
Methods: 120 C57Bl/6J mice (60 males and 60 females) were allocated to four groups (n = 15). They were treated firstly either with 5 mg/mL propylene glycol (PPG) or 100 μg/mL 4NQO in the drinking water for 10 weeks, followed by sterilized water (HO) or 8% EtOH (v/v) for 15 weeks, as follows: PPG/HO, PPG/EtOH, 4NQO/HO, and 4NQO/EtOH (CEUA-UFU, #020/21).

Perceived risk for HIV acquisition among gay, bisexual, and other men who have sex with men (GBMSM) may not align with their actual sexual HIV exposure. Factors associated with low/moderate perceived risk among GBMSM eligible for pre-exposure prophylaxis (PrEP) (based on their high estimated HIV exposure) have been poorly described in Latin America. This is a secondary analysis of a 2018 web-based cross-sectional survey in Brazil, Mexico, and Peru.

Seasonally dry tropical woodlands are vital for climate change mitigation, yet their full potential in carbon storage remains poorly understood. This is largely due to the lack of species-specific allometric models tailored to these ecosystems. To address this knowledge gap, this study aimed to develop species-specific biomass allometric equations (BAEs) for accurately estimating both above- and below-ground biomass of Colophospermum mopane (J.

Partial stenosis of the renal artery causes renovascular hypertension (RVH) and is accompanied by chronic renal ischemia, resulting in irreversible kidney damage. Revascularization constitutes the most efficient therapy for normalizing blood pressure (BP) and has significant benefits for renal function; however, the tissue damage caused by chronic hypoxia is not fully reversed. Mesenchymal stem cells (MSCs) have produced discrete results in minimizing RVH and renal tissue and functional improvements since the obstruction persists.
