Artificial intelligence optimizes the standardized diagnosis and treatment of chronic sinusitis.

Background: Standardised management of chronic sinusitis (CRS) is a challenging but vital area of research. Not only is accurate diagnosis and individualised treatment plans required, but post-treatment chronic disease management is also indispensable. With the development of artificial intelligence (AI), more "AI + medical" application models are emerging.

One-Piece 3D-Printed Pneumatic Catheter: Dual-Segment Design with Integrated Robotics Control for Endovascular Interventions.

Soft robotics have propelled advancements in medical applications such as endovascular interventions through the development of soft steerable catheters. Despite their potential, existing catheters often require intricate manufacturing or complex control systems due to their inherent hysteresis and nonlinear material properties. This study introduces a novel catheter system featuring a 3D-printed hollow tip with two pneumatic bending units, facilitating rotation about two distinct axes without the need for additional fabrication steps.

Bedside Admittance Control of a Dual-Segment Soft Robot for Catheter-Based Interventions.

Robotic catheters enable precise steering of their distal tip while inside the body's blood vessels, and with this ability comes the need for control systems that fit into the clinical workflow. In this study, we propose a novel bedside admittance controller composed of a force/torque sensor with a 3D-printed handle and a low-profile table mount. The controller is intended to be placed at the insertion site to the body and allows simultaneous insertion and steering of a dual-segment fluid-actuated soft robot catheter.

[Effects of high salt diet on renal vascular reactivity in mice detected by laser speckle contrast imaging].

The aim of this study was to conduct experiments using laser speckle contrast imaging (LSCI) technology to investigate the effects of high salt diet on renal vascular reactivity in mice. LSCI is a technology for monitoring blood flow based on the laser speckle principle. It has been widely used to detect microcirculatory functions in tissues such as the skin and brain.

mTORc2 in Distal Convoluted Tubule and Renal K + Excretion during High Dietary K + Intake.

Key Points: High K stimulates mechanistic target of rapamycin complex 2 (mTORc2) in the distal convoluted tubule (DCT). Inhibition of mTORc2 decreased the basolateral Kir4.1/Kir5.

The effect of high-dietary K (HK) on Kir4.1/Kir5.1 and ROMK in the distal convoluted tubule (DCT) is not affected by gender and Cl content of the diet.

Basolateral potassium channels in the distal convoluted tubule (DCT) are composed of inwardly-rectifying potassium channel 4.1 (Kir4.1) and Kir5.

Effects of 17β-estradiol on typical greenhouse gas emissions in aquatic anaerobic ecosystem.

Anaerobic microecosystems designed with different concentrations of 17β-estradiol (17β-E2) (0.0-10,000.0 ng/L) were simulated in this study.
