Article Abstract
To investigate the hemostatic efficacy of ultrasound in flash mode and/or microbubbles-assisted microwave coagulation for active liver hemorrhage. Thirty miniature pigs were randomly divided into five groups. Active hepatic hemorrhage was induced under ultrasound guidance. Treatment groups included microwave ablation (MWA), microbubbles with microwave ablation (MBs + MWA), ultrasound in flash mode with microwave ablation (Flash + MWA), ultrasound in flash mode with microbubbles and microwave ablation (Flash + MBs + MWA), and ultrasound in flash mode with phosphate-buffered saline and microwave ablation (Flash + PBS + MWA). Hemostasis time, blood tests, ultrasound, pathological inspections, and analysis were conducted. The Flash + MBs + MWA group showed the shortest hemostasis time, with 2.25 ± 0.45, 2.42 ± 0.51, and 5.50 ± 0.52 min for diaphragm, gallbladder, and hepatic artery bleeding. Highest blood cell stability and a significantly larger hemostatic lesion range were observed in this group on ultrasound. Pathological analysis revealed varied extents of liver sinus congestion and dilation. The combination of ultrasound contrast microbubbles system and microwave thermal coagulation can effectively treat active hepatic hemorrhage, and microbubbles in ultrasound Flash mode have an enhancing effect on microwave coagulation hemostasis.

The extraction methods of polysaccharides significantly affect their characteristics and functional properties. However, the impact of flash extraction and ultrasound-assisted extraction on the physicochemical properties and prebiotic effect of Lyophyllum decastes polysaccharides remains poorly understood. In this study, polysaccharides from Lyophyllum decastes were extracted using ultrasound-assisted and flash extraction methods, yielding the fractions LDP-R and LDP-S after purification, respectively.

FLASH radiotherapy is a promising technique based on the delivery of ultra-high dose rates (UHDR) to spare healthy tissue. Robust quality assurance (QA) is required to ensure a safe delivery of the treatment. QA devices such as phantoms and ionization chambers (ICs) are typically made out of polymeric materials to ensure water equivalence.

Activation of the NLR-family pyrin domain-containing 3 (NLRP3) inflammasome has been associated with diabetic retinopathy progression. We have synthesized a highly sensitive molecular imaging probe, InflammaProbe-2, as an early detection diagnostic tool for the in vivo molecular imaging of NLRP3 inflammasomes in living diabetic retina. The ability of InflammaProbe-2 for the targeted visualization of the NLRP3 inflammasome was assessed using an enzyme-linked immunosorbent assay (ELISA) by comparing its ability to inhibit the NLRP3-mediated secretion of IL-1β.

Background: Patients with liver failure may be accompanied by cerebral edema and elevated intracranial pressure (ICP). The effect of plasma adsorption (PA) and low-volume plasma exchange (PE) on ICP were unclear.
Methods: A prospective observational cohort study was conducted in patients with acute-on-chronic liver failure (ACLF) receiving PA followed immediately by low-volume PE.

To simultaneously fit multiple-pool effects, spectrally selective 3D chemical exchange saturation transfer (CEST) imaging typically requires single-shot readouts to save time. However, to date, fast low angle shot (FLASH) and echo planar imaging (EPI) have been the primary pulse sequences used for this purpose. They suffer from low signal-to-noise ratio (SNR) or image distortion related to B0 field inhomogeneity.
