In the recent years US has gained wide diffusion as a useful imaging tool in the evaluation of musculoskeletal disorders. Recognized advantages of US over the other imaging modalities are low costs, non-invasiveness, possibility to perform a dynamic examination and readiness. Unfortunately, US has a long learning curve and allows good results only when performed by well-trained and experienced examiners. Specifically, utilization of the recent small transducers allows to perform dynamic examination of the hand during flexion-extension movements of the fingers, while their high frequency (till 15 MHz) have increased the possibility to evaluate small anatomic structures of the hand and wrist as well as to detect subtle pathologic changes. The purpose of this article is to present first the normal basic anatomy and US appearance. Then the main pathological conditions including joint and tendon disorders, foreign bodies and other traumatic lesions, entrapment neuropathies and expansible lesions will be presented.

Atomic-Level Tin Regulation for High-Performance Zinc-Air Batteries.

The trade-off between the performances of the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) presents a challenge in designing high-performance aqueous rechargeable zinc-air batteries (a-r-ZABs) due to sluggish kinetics and differing reaction requirements. Accurate control of the atomic and electronic structures is crucial for the rational design of efficient bifunctional oxygen electrocatalysts. Herein, we designed a Sn-Co/RuO trimetallic oxide utilizing dual-active sites and tin (Sn) regulation strategy by dispersing Co (for ORR) and auxiliary Sn into the near-surface and surface of RuO (for OER) to enhance both ORR and OER performances.

The hippocampal dentate gyrus (DG) is thought to orthogonalize inputs from the entorhinal cortex (pattern separation) and relay this information to the CA3 region. In turn, attractor dynamics in CA3 perform a pattern completion or error correction operation before sending its output to CA1. In a mouse model of congenital hypoplasia of the DG, a deficiency in the (Wls) gene, specifically in cells expressing , which targets neuronal progenitors, led to an almost total absence of dentate granule cells and modestly impaired performance in spatial tasks.

Personalized sports training plans are essential for addressing individual athlete needs, but traditional methods often need to integrate diverse data types, limiting adaptability and effectiveness. Existing machine learning (ML) and rule-based approaches cannot dynamically generate context-specific training programs, reducing their applicability in real-world scenarios. This study aims to develop a Generative Adversarial Network (GAN)- based framework to create context-specific training plans by integrating numeric attributes (e.

Article Synopsis
- Laser-structuring techniques, particularly Direct Laser Interference Patterning, can significantly enhance the performance of pure Ni electrodes in water electrolysis by optimizing their structure.
- A study revealed that the spatial distance between laser-structures is critical for improving electrode performance, resulting in an increase in the electrochemically active surface area by up to 12 times compared to nonstructured electrodes.
- Optimal structuring leads to lower onset potential and overpotential during the oxygen evolution reaction due to the superhydrophilic surface, which enhances bubble growth dynamics and minimizes electrode resistance.
Physiological effects of nasal high flow therapy during exercise in patients with chronic obstructive pulmonary disease: A crossover randomised controlled trial.

Background: Nasal high flow (NHF) has been proposed to sustain high intensity exercise in people with COPD, but we have a poor understanding of its physiological effects in this clinical setting.
Research Question: What is the effect of NHF during exercise on dynamic respiratory muscle function and activation, cardiorespiratory parameters, endurance capacity, dyspnoea and leg fatigue as compared to control intervention.
Study Design And Methods: Randomized single-blind crossover trial including COPD patients.
