Article Abstract
The settling process of marine microplastics (MPs) is crucial research concerning the transport and movement of MPs. The settling processes of MP fibers that possess a cylindrical geometry are affected by environmental factors and properties. In this study, a three-dimensional numerical model for the still water settling of MPs with complex shapes was constructed using the lattice Boltzmann method (LBM) and the immersed boundary method (IBM). The fully resolved settling simulation of cylindrical MPs was achieved, and the model results demonstrated good agreement with the semi-empirical settling velocity formulas. Based on the simulation results, the critical aspect ratio of the cylindrical MP was found to be between 0.93 and 0.94. Near this critical aspect ratio, there is a decline in the drag force. Additionally, it was found that the angular displacement and aspect ratio influence horizontal movement but not the vertical settling velocity, while the density only affects vertical movement.

Background: Chagas heart disease (ChD) is a significant public health concern in Latin America, contributing to a high incidence of sudden cardiac death (SCD). Despite advances in heart failure treatment, management of Chagas cardiomyopathy has not progressed accordingly. While ICDs are effective for primary and secondary prevention in other conditions, patients with ChD often experience more frequent episodes of ventricular tachycardia, and ICD use may provide a negative impact and increase mortality.

Objective: To evaluate clinical and laboratory effectiveness of ultrasound treatment for purulent wounds.
Material And Methods: The study enrolled 46 patients with purulent wounds divided into the main group (23 patients, ultrasonic treatment) and the control group (23 patients, traditional treatment). We assessed treatment effectiveness considering visual data, quality of granulation tissue, wound defect area and marginal epithelialization, complete blood count and C-reactive protein.

Anti-Aβ antibodies are important tools for identifying structural features of aggregates of the Aβ peptide and are used in many aspects of Alzheimer's disease (AD) research. Our laboratory recently reported the generation of a polyclonal antibody, pAb2AT-L, that is moderately selective for oligomeric Aβ over monomeric and fibrillar Aβ and recognizes the diffuse peripheries of Aβ plaques in AD brain tissue but does not recognize the dense fibrillar plaque cores. This antibody was generated against 2AT-L, a structurally defined Aβ oligomer mimic composed of three Aβ-derived β-hairpins arranged in a triangular fashion and covalently stabilized with three disulfide bonds.

The low dose dexamethasone stimulation test (LDDST) is routinely used in canine medicine but in the few cases in guinea pigs diagnosed with hypercortisolism, the adrenocorticotropic hormone (ACTH) stimulation test was used. The objective of the authors was to conduct a pilot study and find out if the standard test used in dogs can be used in this species.A 4-year-old intact female hairless guinea pig showed bilaterally enlarged adrenal glands and high cortisol levels.

The effect of shape and size of embolic agents on embolization phenomena has been discussed clinically for transcatheter arterial chemoembolization (TACE). We numerically discussed the unique embolization behavior of new deformable toroidal microparticles in blood vessels by computational fluid dynamics simulations. We employed an Eulerian-Eulerian (full Eulerian) fluid-structure interaction (FSI) method to analyze the flow and deformation behaviors of a deformable torus in a cylindrical pipe.
