Guillain-Barré syndrome in patients with multiple myeloma: three cases report and literature review.

Background: Multiple myeloma (MM) with Guillain-Barré syndrome (GBS) is relatively rare, and the specific mechanism is still unclear. The previous infection, surgery, and medication use may have contributed to the occurrence of GBS. The use of bortezomib in patients with MM can easily lead to peripheral neuropathy, which is similar to the symptoms of GBS, making it challenging to diagnose GBS.

Osimertinib, a third-generation EGFR-TKI, is currently one of most efficient treatments in clinical practice. However, it has a potentially fatal side effect: interstitial lung disease (ILD).

Li Quasi-Grotthuss Topochemistry Transport Enables Direct Regeneration of Spent Lithium-Ion Battery Cathodes.

Direct regeneration of spent lithium-ion batteries offers economic benefits and a reduced CO footprint. Surface prelithiation, particularly through the molten salt method, is critical in enhancing spent cathode repair during high-temperature annealing. However, the sluggish Li transport kinetics, which predominantly relies on thermally driven processes in the traditional molten salt methods, limit the prelithiation efficiency and regeneration of spent cathodes.

Multimodality imaging features of systemic amyloidosis: a case report.

Background: Systemic light chain amyloidosis is a rare and debilitating disease, especially for which initially presented with digestive tract involvement. Myocardial amyloidosis is highly aggressive with generally poor prognosis and often resulted in missed diagnosis or misdiagnosis with routine examination tools. Multimodality imaging play an important role in diagnosing the amyloidosis effect on multiple organs.

A novel therapeutic strategy for leukopenia: Miltefosine activates the Ras/MEK/ERK pathway to promote neutrophil differentiation.

Leukopenia, marked by diminished white blood cell (WBC) counts, presents significant challenges in the management of hematological malignancies and immunocompromised patients. This study evaluated the therapeutic potential of miltefosine (MFS), a phospholipid analogue, for treating leukopenia. In vitro studies using HL60 and NB4 cells revealed that MFS effectively promoted neutrophil differentiation and function, evidenced by the upregulation of surface markers CD11b, CD11c, CD14, and CD15, as well as enhanced bactericidal activity assessed through the NBT reduction assay.

Extracellular vesicles-derived MicroRNA-145-5p is upregulated in the uterine fluid of women with endometriosis and impedes mouse and human blastocyst development.

Previous work indicated that the implantation and pregnancy rates of women with endometriosis are lower than those of healthy women during in-vitro fertilisation and embryonic transfer. And there are numerous microRNAs (miRNAs) in human uterine luminal fluid (ULF), some of which are associated with early preimplantation development of embryos. In our study, we sought to determine whether miRNAs in the ULF are differentially expressed between women with and without endometriosis and to uncover the association of miRNAs with the development potential of blastocysts.

Microbiome-proteome analysis of gastrointestinal microbiota and longissimus thoracis muscle proteins in cattle with high and low grades of marbling.

Marbling is a key indicator of the meat quality of ruminants. Gastrointestinal microbiota may regulate the formation of marbling by influencing the nutritional metabolism of animals. This study analyzed the composition and functional differences of microbiota in the rumen and cecum, the differences in volatile fatty acids (VFAs) content in the longissimus thoracis muscle, and the differences in protein abundance in the longissimus thoracis muscle of ruminants with different marbling grades through microbiome-proteome analysis.

Construction and Isolation of Recombinant Vaccinia Virus by Homologous Recombination Using Fluorescent Protein Markers.

Genetic modification of vaccinia virus (VACV) is a fundamental and valuable research technique in elucidating the function of VACV genes, as well as the development as vaccine vectors for other infectious diseases, oncolytic therapeutics for cancers, and protein expression systems in mammalian cells. Because of the large size of poxvirus genome and noninfectious feature of the naked viral DNA, construction of recombinant VACV relies on intracellular homologous recombination between transfected DNA and replicating viral DNA in infected cells occurred in VACV infected cells. The efficiency of homologous recombination event for vaccinia virus is relatively low, and recombinant viruses only account for 0.

Overtone Excitation of Nitrogen Molecules via Stimulated Raman Pumping.

Nitrogen bond activation is a pivotal process in chemistry, with bond excitation being fundamental to understanding the underlying mechanisms, making the preparation of molecules in specific quantum states crucial. Here we report the first overtone excitation of the N molecule from XΣ( = 0, = 0, 1, and 2) to XΣ( = 2, = 0, 1, 2, and 3) using the stimulated Raman pumping (SRP) method in a pulsed molecular beam. N was detected using 2+1 resonance-enhanced multiphoton ionization through the a″Σ state.

Self-Adaptive Layering Structure of Nanoconfined Fe-Ni Liquids: Origin of the Liquid-Liquid Phase Transition.

Metallic liquids under confinement exhibit different properties compared to those of their corresponding bulk phases, such as miscibility, diffusion, and phase transitions. Unfortunately, the challenges in experimentally characterizing Fe-Ni liquids at the nanoscale and the high cost of first-principles simulations hindered the atom-level understanding that is necessary for controlling Fe-Ni liquids. Here, we report a comprehensive molecular dynamics study of the liquid Fe-Ni alloy confined within nanoslits.

Tuning the local electronic structure of CoV-ZIF through bimetallic synergies as a bifunctional electrocatalyst for overall water splitting.

Co-based bimetallic zeolite imidazolate frameworks (ZIFs) have been shown as promising electrocatalysts for the oxygen evolution reaction, but their electronic structure's influence on the catalytic performance for overall water splitting still needs further investigation. In this study, CoV-ZIF, structured as two-dimensional (2D) nanosheet arrays, are grown on nickel foam using one-step co-precipitation strategy. Owing to the synergistic effects of vanadium (V) and cobalt (Co) reasonably regulating the electronic structure, the synthesized bimetallic ZIFs demonstrate superior catalytic performance, which required the overpotentials of only 227 and 68 mV to achieve a current density of 10 mA cm in 1 M KOH for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER), respectively.
