Article Synopsis
  • - Epstein-Barr virus (EBV)-associated lymphoproliferative disease is a group of disorders where infected lymphocytes continually multiply, leading to severe skin issues like hypersensitivity to mosquito bites and blistering skin eruptions.
  • - A study collected blister fluids from three patients with this condition and found high levels of NK and γδ T cells that indicate strong activation, marking them as potential targets for EBV infection.
  • - Additionally, elevated concentrations of tumor necrosis factor (TNF)-α were found in the blister fluids, suggesting that these local skin reactions may result from the infiltration of EBV-infected lymphocytes and high TNF-α levels.

Background: Familial Mediterranean fever (FMF) is an autoinflammatory disease caused by mutations in the MEFV gene. Mutations in exon 10 are associated with typical FMF phenotypes, and patients with exon 10 mutations have higher serum levels of interleukin (IL)-18 both during attacks and afebrile phases, compared to those without exon 10 mutations. However, longitudinal changes of serum IL-18 in FMF have not been fully characterized.

Background: Food protein-induced enterocolitis syndrome (FPIES) is an uncommon, non-IgE-mediated food allergy. We recently described a significant increase in fecal eosinophil-derived neurotoxin (EDN) after ingestion of the causative food. However, little is known about the activation status of circulating eosinophils in patients with an acute FPIES reaction.

In our previous study, we introduced a new hybrid approach to effectively approximate the total force on each ion during a trajectory calculation in mass spectrometry device simulations, and the algorithm worked successfully with SIMION. We took one step further and applied the method in massively parallel general-purpose computing with GPU (GPGPU) to test its performance in simulations with thousands to over a million ions. We took extra care to minimize the barrier synchronization and data transfer between the host (CPU) and the device (GPU) memory, and took full advantage of the latency hiding.
