Introduction: Rib resection and remodeling have gained attention as cosmetic procedures to enhance body contours, particularly waist-to-hip ratio. Historically, rib resection has been used for medical reasons; however, plastic surgeons have recently adopted it for aesthetic purposes. However, concerns remain regarding the safety and effectiveness of the procedure, particularly due to the potential for complications, such as pneumothorax, chronic pain, and impaired respiratory function.

The continuous development and application of pesticides in agriculture require robust multiresidue detection methods to guarantee food safety. This study introduces a novel method for multiresidue determination of pesticides in eggplants using the QuEChERS procedure, incorporating a clean-up step using carbon nanotubes stabilized in chitosan sponge (CNT-CS) and ultra-high performance liquid chromatography with tandem mass spectrometry (UHPLC-MS/MS) for analysis. Upon identifying the optimal extraction conditions, various sorbents were assessed for their efficacy in the dispersive solid-phase extraction (d-SPE).

Reproductive effects of the insecticide acephate on a springtail and an enchytraeid in a subtropical soil.

Environ Toxicol Chem

January 2025

Universidade do Estado de Santa Catarina (UDESC Lages), Departmento de Solos e Recursos Naturais, Lages, SC, Brazil.

The widespread use of acephate, a common insecticide, raises concerns about its potential impacts on nontarget soil organisms. This study investigated the chronic effects of acephate on the reproduction of two key soil fauna species, the springtail Folsomia candida and the enchytraeid Enchytraeus crypticus. We exposed these organisms to acephate in both natural Cambisol soil and tropical artificial soil (TAS) to assess potential impacts under different environmental conditions.

A long-term successful implant-supported prosthesis requires the creation of a passively fitting framework, based on an accurate intraoral digital implant scan. According to dental literature, splinted implant scan bodies (ISBs) provide higher intraoral scanning accuracy than non-splinted techniques. This technique presents a structured approach for splinting multi-unit abutment scan bodies (MUASBs) using customized manufactured devices to facilitate the recording of definitive intraoral implant scans.

Calciphylaxis is a rare and serious disorder characterized by vascular calcification and occlusion of the microvessels in the dermis, subcutaneous adipose tissue, visceral organs, and musculature. Studies have suggested that the major risk factors for developing calciphylaxis are chronic kidney disease and secondary hyperparathyroidism. Its diagnosis is clinical, and the treatment includes a multidisciplinary approach, although there are no clinical protocols based on randomized clinical trials.

Background: When a family decides to donate the organs or tissues of their child with brain death, it is necessary to consider which organs or tissues will be donated. This phenomenon presents an ethical dilemma that is underexplored in the scientific literature, making it essential to examine this context to understand how refusals occur within donations.

Objective: To analyze the rates and trends of specific refusals for each organ and tissue from pediatric donors with brain death occurring between 2001 and 2020 in an Organ Procurement Organization in the State of São Paulo, Brazil.

While research on auditory attention in complex acoustical environment is a thriving field, experimental studies thus far have typically treated participants as passive listeners. The present study-which combined real-time covert loudness manipulations and online probe detection-investigates for the first time to our knowledge, the effects of acoustic salience on auditory attention during live interactions, using musical improvisation as an experimental paradigm. We found that musicians were more likely to pay attention to a given co-performer when this performer was made sounding louder or softer; that such salient effect was not owing to the local variations introduced by our manipulations but rather likely to be driven by the more long-term context; and that improvisers tended to be more strongly and more stably coupled when a musician was made more salient.

The two main extensions of rain forest in South America are the Amazon (Amazônia) and the Atlantic rain forest (Mata Atlântica), which are separated by a wide 'dry diagonal' of seasonal vegetation. We used the species-rich tree genus to test if Amazônia-Mata Atlântica dispersals have been clustered during specific time periods corresponding to past, humid climates. We performed hybrid capture DNA sequencing of 810 nuclear loci for 453 accessions representing 164 species that included 62% of Mata Atlântica species and estimated a dated phylogeny for all accessions using maximum likelihood, and a species-level tree using coalescent methods.

Pharmaceutical excipients, commonly known as inactive ingredients, encompass any substance aside from the active ingredient that fulfills a distinct and vital role in a formulation. Their purpose is to enhance specific characteristics, whether associated with the performance of the formulation or aspects related to patient comfort, safety, and acceptability. Because of the limited toxicity studies provided, and the several allergic and toxic side effects that have been reported throughout the years, it is not trivial for the regulatory agencies to approve inactive ingredients for human use.

A huge challenge after the emergence of COVID-19 has been the discovery of effective antiviral drugs. Although remdesivir (RDV) emerged as one of the most promising drugs, its pharmaceutical formulation Veklury® is limited by moderate efficacy, high toxicity and need for parenteral administration. The aim of the present work was to develop a liposomal formulation of RDV for pulmonary administration and evaluate its efficacy in models of COVID-19.

Transforming lignocellulosic biomass waste into value-added materials like porous carbons offers a sustainable and increasingly important solution for its efficient management within a circular economy framework. Although the heteroatom-doping process enhances oxygen- or nitrogen-containing functionalities on porous carbons, it often leads to losses in structural integrity and other key functionalities. This study presents a novel protocol to produce N-doped porous carbons that efficiently introduces nitrogen groups while improving surface area, microporosity definition and the concentration of oxygen-containing functionalities.

This study aims to investigate the effects of material compatibility, variable cooling rates, and crown geometry on thermal stress development in porcelain-veneered lithium disilicate (PVLD) and porcelain-veneered zirconia (PVZ) dental crown systems, and subsequently anticipate parameters for their optimum performance. An anatomically correct 3D crown model was developed from STL files generated using 3D scans of the experimental crown sample. Next, the viscoelastic finite element model (VFEM) based on the 3D crown model was developed and validated for anatomically correct bilayer PVLD and PVZ crown systems.

The growing world population and climate change are key drivers for the increasing pursuit of more efficient and environmentally-safe food production. In this scenario, the large scale use of herbicides demands the development new technologies to control and monitor the application of these compounds, due to their several environmental and health-related problems. Motivated by all these issues, in this work, a hybrid graphene/boron nitride nanopore is explore to detect/identify herbicide molecules (Glyphosate, AMPA, Diuron, and 2,4-D).
