Coupling ion exclusion and interaction screening within sub-nanoconfinement channels in novel porous material membranes hold great potential to realize highly efficient ion sieving, particularly for high-performance lithium-ion extraction. Diverse kinds of advanced membranes have been previously reported to realize this goal but with moderate performance and complex operations gained. Herein, these issues are circumvented by preparing the consecutive and intact imine-linked three-dimensional covalent organic framework (i.

Methods: A retrospective cohort study was conducted. The clinicopathological data of 40 pairs of donors and recipients who underwent OLT from May 2018 to August 2023 were analyzed.
Objective: Hematomas of the liver graft, that is, postintervention, subcapsular or intrahepatic are rare yet potentially fatal complications following liver transplantation (LT), necessitating immediate diagnosis and management to avert devastating outcomes. This study was aimed to introduce our approach to manage graft hematoma subsequent to LT.
Methods: Among 131 orthotopic liver transplantations (OLT) conducted at our institution between January 2017 and May 2023, 3 cases of intrahepatic (n = 2) and extrahepatic (n = 1) hematoma were confirmed through computed tomography (CT) within 10 days after LT.
Caroli disease (CD) is a congenital disease of the intrahepatic biliary system, which manifests as cystic dilatation of the intrahepatic bile ducts. The disease has a low incidence and atypical clinical manifestations; therefore, it can be easily misdiagnosed. Hepatitis B infection is a viral infection that affects liver cells, leading to degeneration, necrosis, and regeneration of the cells and formation of false lobules, and ultimately nodular cirrhosis, which can lead to liver dysfunction and liver failure.

Normothermic machine perfusion (NMP) has the potential to increase organ availability, yet its efficacy is hampered by the inflammatory response during machine perfusion. Mouse liver ischemia-reperfusion injury (IRI) models, discarded human liver models, and porcine marginal liver transplantation models were utilized to investigate whether farnesoid X receptor (FXR) activation could mitigate inflammation-induced liver damage.

Therefore, metal nanogaps show great prospects in enhancing light-matter interaction. However, it is still challenging to fabricate large-scale (centimeter scale) nanogaps with precise control of gap size at nanoscale, limiting the practical applications of metal nanogaps.

However, long-term use of HBIG causes many adverse effects. The aim of this study was to evaluate the effect of nucleoside analogs entecavir combined with short-term HBIG in preventing HBV recurrence after LT.

Liver transplant recipients are at an increased risk of opportunistic infections (OI) due to immunosuppressive therapy compared to those with normal immunity. Early diagnosis and timely implementation of treatment are critical for the successful treatment of these infections.

We report a metal-insulator-metal based four-port all-optical logic gate device containing two parallel straight waveguides and a ring resonator. We employ the scattering matrix method to analyze the coupling mechanisms of the hybrid waveguide and adopt the finite-difference time-domain method to design four fundamental logic functions of AND, OR, XOR, and NOT based on the all-optical coherent control of the four-port system under three symmetrically incident conditions.

Invasive fungal infections, of which the most common are candidiasis and aspergillosis, are among the most important and fatal complications in solid organ transplantation. They continue to be a significant cause of morbidity and mortality in patients with involvement of the central nervous system (CNS) because of the poor CNS penetration of antifungal medications. Voriconazole yields fungicidal drug concentrations in the CNS, but its use is limited in solid organ transplant patients because of its metabolic interactions with immunosuppression.

A continuous blood supply to organs using machine perfusion from procurement and preservation to implantation facilitates complete prevention of ischemia reperfusion injury and permits ex situ functional assessment of donor livers before transplantation. In this manuscript, we provide a step-by-step ischemia-free liver transplantation protocol in which an ex situ normothermic machine perfusion apparatus is used for pulsatile perfusion through the hepatic artery and continuous perfusion of the portal vein from human donor livers to recipients.

By using theoretical analysis and structural optimization, we numerically demonstrate a four-channel all-optical logic gate device that can switch three basic logic operations on each NR only by controlling the phase differences of incident beams. This device is ultra-compact in size and shows high extensibility for parallel logic operations, which may be applied in future high-speed on-chip integrated optical computing.
