Prognostic value of Prognostic Nutritional Index (PNI) for 5-year recurrence-free survival in surgically resected gastrointestinal stromal tumors.

Background: Recent studies have investigated the role of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic inflammation index (SII), and prognostic nutritional index (PNI) on prognosis for various malignancies. However, the value of these markers in determining the prognosis for gastrointestinal stromal tumors (GIST) remains controversial. We investigated the effect of NLR, PLR, SII, and PNI on 5-year recurrence-free survival (RFS) in patients with surgically resected GIST.

Tocilizumab's effect on cognitive deficits induced by intracerebroventricular administration of streptozotocin in Alzheimer's model.

Neuroinflammation plays pivotal roles in the pathogenesis of Alzheimer's disease (AD). IL-6 is pleiotropic cytokine which plays significant pathological role in inflammatory diseases and causes prolonged inflammation. Additionally, IL-6 activates microglia cells and enhances the accumulation of amyloid-β peptides.
