The rupture of the Fundão dam in Brazil released tons of mining tailings into the Doce River Basin (DRB). This investigation aimed to determine the bioaccumulation of metals in soft tissues of the bivalve Corbicula fluminea exposed to sediments collected in the DRB in four periods (just after, 1, 3, and 3.5 years after the dam rupture). In the exposure bioassays, the concentrations of Al, As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn in sediments and bivalve soft tissues were quantified. The concentration of some elements (As, Cd, Mn, and Al) in sediments exceeded the federal limits or regional backgrounds at some sampling sites, but their concentrations tended to decrease over time. However, higher concentrations of many elements were detected in the winter of 2019. Several elements were detected in C. fluminea soft tissues, but the bioaccumulation factors were generally low or not related to those elements associated with the ore tailings, evidencing that the bioavailability of metals to bivalves, in laboratory conditions, was limited.

Introduction: Developmental dysplasia of the hip (DDH) poses challenges for component positioning during total hip arthroplasty (THA) secondary to abnormal bone morphology, soft-tissue contractures, and hip center migration. The objective of this study was to evaluate the radiographic and clinical outcomes of THA for DDH performed with robotic assistance versus manual (M) technique.
Methods: A retrospective review identified 115 patients with Crowe II to IV dysplasia undergoing primary THA at a single institution from 2016 to 2022.
Electroporation is a promising technology utilizing electrical pulses for macromolecule delivery and soft-tissue ablation, with applications that include next-generation prophylactics and the treatment of genetic diseases such as cancer. This study demonstrates a high-throughput capable 3D tissue culture model for quantification of the reversible and irreversible electroporation thresholds for a given electroporation protocol. By using a non-uniform electric field and analyzing the spatial distribution of transfected cells, both reversible and irreversible thresholds can be identified within a single sample, increasing the efficiency at which electroporation protocols can be characterized, especially for in vivo translation.

Facial feminization surgery (FFS) reshapes masculine facial attributes to align with feminine norms, yet normative anthropometric data for Asian populations remain sparse. We therefore quantified sex-related 3-dimensional (3D) facial metrics in healthy Asian adults to delineate dimorphic benchmarks for surgical planning. We prospectively recruited 40 healthy Asian adults (20 males, 20 females; age 18 to 45 years, mean 28.

Vagus nerve stimulation (VNS) is a promising therapy for neurological and inflammatory disorders across multiple organ systems. However, conventional rigid interfaces fail to accommodate dynamic mechanical environments, leading to mechanical mismatches, tissue irritation, and unstable long-term interfaces. Although soft neural interfaces address these limitations, maintaining mechanical durability and stable electrical performance remains challenging.
