Calcineurin inhibitors (CNIs) are effective agents used for prevention of graft-vs-host disease after allogeneic hematopoietic stem cell transplant or for organ rejection in solid-organ transplant. However, CNIs have a wide range of adverse effects that may necessitate changing to another CNI or immunosuppressive agent. We report a case of acute myeloid leukemia in which achalasia developed after exposure to tacrolimus, as revealed by esophagram results. The patient's symptoms and signs were ameliorated after a change to cyclosporine. This case is the first in the literature to reveal achalasia associated with tacrolimus. Achalasia should be part of a differential diagnosis of upper gastrointestinal symptoms in patients undergoing transplant, and changing to another CNI may be a useful therapeutic intervention.

Postnatal establishment of enteric metabolic, host-microbial and immune homeostasis is the result of precisely timed and tightly regulated developmental and adaptive processes. Here, we show that infection with the invasive enteropathogen Typhimurium results in accelerated maturation of the neonatal epithelium with premature appearance of antimicrobial, metabolic, developmental, and regenerative features of the adult tissue. Using conditional Myd88-deficient mice, we identify the critical contribution of immune cell-derived mediators.

While iron (Fe) is essential for life and plays important roles for almost all growth related processes, it can trigger cell death in both animals and plants. However, the underlying mechanisms for Fe-induced cell death in plants remain largely unknown. S-nitrosoglutathione reductase (GSNOR) has previously been reported to regulate nitric oxide homeostasis to prevent Fe-induced cell death within root meristems.

Solid polymer electrolytes (SPEs) are promising candidates for lithium metal batteries (LMBs) owing to their safety features and compatibility with lithium metal anodes. However, the inferior ionic conductivity and electrochemical stability of SPEs hinder their application in high-voltage solid-state LMBs (HVSSLMBs). Here, a strategy is proposed to develop a dual-anion-rich solvation structure by implementing ferroelectric barium titanate (BTO) nanoparticles (NPs) and dual lithium salts into poly(vinylidene fluoride) (PVDF)-based SPEs for HVSSLMBs.

Gemcitabine + oxaliplatin (GemOx) with rituximab, a standard salvage therapy, yields complete response (CR) rates of approximately 30% and median overall survival (OS) of 10-13 months. Patients with refractory disease fare worse, with a CR rate of 7% for subsequent therapies and median OS of 6 months.
