Cognitive representation of gait: differences in memory structures between individuals after total knee arthroplasty and total hip arthroplasty.

The objective was to examine differences in the gait-specific cognitive representation structures between individuals after total knee- (TKA) and after total hip-joint arthroplasty (THA). The cognitive representation structure was compared between three groups: 1. three months after TKA (n = 12), 2.

Brazil's response to public health emergencies in 2023: lessons for the international community.

Objective: To describe the Brazilian experience of responding to public health emergencies in 2023, the organizational structure, and epidemiological characteristics.

Methods: Three emergencies (case studies) that occurred during the study year were analyzed according to the actions implemented during the response and the impacts on the population. The public health emergencies were summarized and analyzed through research on official documents and websites of the Ministry of Health and local health authorities.

Mitochondrial Complex I and ROS control synapse function through opposing pre- and postsynaptic mechanisms.

Neurons require high amounts energy, and mitochondria help to fulfill this requirement. Dysfunctional mitochondria trigger problems in various neuronal tasks. Using the neuromuscular junction (NMJ) as a model synapse, we previously reported that Mitochondrial Complex I (MCI) subunits were required for maintaining NMJ function and growth.

A color-coordinated approach to the flow synthesis of silver nanoparticles with custom morphologies.

In an effort to meet the high demand for silver nanostructures in both research and consumer applications, we devise a simple and readily scaleable photochemical method through which silver nanostructures of varying morphologies, sizes, and optical properties can be synthesized using batch and flow photochemical strategies. For the latter we build upon the application of a wrapped-lamp photochemical flow system recently developed by our group to enable sequential irradiation with several wavelengths of LEDs in series in an approach that we describe as "plasmon pushing". We find that this strategy can accelerate the conversion of silver nanoparticle seeds to decahedral and triangular nanostructures, and that with it we have control over the tuning of the size and optical properties of triangular nanostructures in the red and near-IR regions.

Connection between -electron correlations and magnetic excitations in UTe.

The detailed anisotropic dispersion of the low-temperature, low-energy magnetic excitations of the candidate spin-triplet superconductor UTe is revealed using inelastic neutron scattering. The magnetic excitations emerge from the Brillouin zone boundary at the high symmetry and points and disperse along the crystallographic -axis. In applied magnetic fields to at least = 11 T along the , the magnetism is found to be field-independent in the ( 0) plane.
