By combination of continuous hemofiltration (CHF) with plasma exchange therapy we successfully treated a patient with subacute type fulminant hepatitis to keep her consciousness alert. The patient was a 55-year-old woman who admitted because of severe jaundice. On the 51st day after the onset she had consciousness disturbance and was transferred to our hospital. We started the therapy of CHF and plasma exchange at the patient's hepatic coma grade 4. On the 5th day her consciousness level recovered to grade 2 and we could keep the level for almost 2 weeks. This combination therapy seemed good not only for the improvement of consciousness of patients in hepatic coma but also to support the hepatic function of almost ahepatic patients.

Alzheimer's disease (AD) is a prevalent neurodegenerative disorder characterized by amyloid-beta (Aβ) aggregation, primarily involving the peptides Aβ40 and Aβ42. Human serum albumin (HSA) has emerged as a potential therapeutic agent due to its ability to bind Aβ, inhibit aggregation, and promote disaggregation. This study quantitatively examined the interactions of HSA with both monomeric and aggregated forms of Aβ40 and Aβ42 using fluorescence techniques, including bulk steady-state fluorescence, fluorescence anisotropy, time-resolved fluorescence, and Fluorescence Correlation Spectroscopy (FCS).

Background And Objectives: Serum immunoglobulin G (IgG) and total protein are used to monitor plasmapheresis donor safety. However, there is a lack of information from large donor cohorts to determine the best use of these measurements.
Materials And Methods: We identified 230,144 plasmapheresis donors making their first donation between 1 July 2020 and 31 March 2024.

Background: Cold agglutinin disease (CAD) or syndrome (CAS) can be particularly challenging when autologous stem cell transplant (ASCT) is needed. Standard peripheral blood stem cell (PBSC) collection and manipulation involve ex vivo blood manipulations at lower than body temperature, predisposing to agglutination during graft collection, handling, processing, and infusion.
Study Design And Methods: We describe the first case of ASCT for relapsing lymphoma in a patient with high-titer CAD requiring anti-complement therapy and chronic transfusion.

Metallofullerenols and fullerenols have attracted attention due to their remarkable ability to interact with various biologically relevant molecules, paving the way for biomedical applications, ranging from medical imaging techniques to drug carriers, acting with increased efficiency and reduced side effects. In this work, we investigated the effects of two fullerene derivatives, Gd@C(OH) and C(OH), on erythrocyte membrane components under oxidative stress conditions induced by 2,2'-azobis(2-amidinopropane) dihydrochloride (AAPH) as a source of peroxyl radicals. The results demonstrated that gadolinium encapsulation within the fullerene cage enhanced the electron affinity of Gd@C(OH), resulting in stronger antioxidant activity.
