Aim: Plasma protein binding (PPB), as a significant influenced factor of pharmacokinetic and pharmacodynamic properties of a medicine, is a suitable index for therapeutic drug monitoring (TDM) strategies. A suitable measurement technique of PPB of patients is in urgent need and attracts many analysts' attention. Results & methodology: In this study, a novel method was proposed to analyze free drug concentration and total drug concentration (C) successively in one unit with a sample. All RSDs were less than 3%. The absolute recovery of C ranged from 98.1 to 101.2%.
Discussion & Conclusion: It is extremely valuable to consider PPB as an important index for TDM, perfecting information of medication, reflecting the disease condition more comprehensively, providing assistance for doctors to adjust the dose regimen. The proposed technique, convenience, accuracy and without the influence of plasma condition, provides a feasible method to monitor PPB of various patients, facilitating the popularization of monitoring PPB in TDM.

Background And Objectives: Cognitive deficits represent a major long-term complication of anti-leucine-rich, glioma-inactivated 1 encephalitis (LGI1-E). Although severely affecting patient outcomes, the structural brain changes underlying these deficits remain poorly understood. In this study, we hypothesized a link between white matter (WM) networks and cognitive outcomes in LGI1-E.

Background And Objectives: Invasive procedures may delay the diagnostic process in multiple sclerosis (MS). We investigated the added value of serum neurofilament light chain (sNfL), glial fibrillary acidic protein (sGFAP), chitinase-3-like 1 (sCHI3L1), and the immune responses to the Epstein-Barr virus-encoded nuclear antigen 1 to current MS diagnostic criteria.
Methods: In this multicentric study, we selected patients from 2 prospective cohorts presenting a clinically isolated syndrome (CIS).

Background: Insulin resistance often occurs in patients with chronic kidney disease (CKD) owing to mineral and bone metabolism disorders. Fibroblast growth factor (FGF)-23 and soluble klotho (s-KL) play crucial roles in linking CKD with mineral and bone metabolism.
Objective: This study aimed to examine the relationship between insulin resistance and FGF-23 and s-KL in patients with non-diabetic pre-dialysis patients with CKD.
Effect of iron fortification and prebiotics on iron biomarkers in anemic rats.

One of the biggest public health problems globally is that of iron deficiency anemia. The present research aimed to determine the effect of prebiotics along with iron fortification on iron biomarkers in female anemic rats as some evidence suggests that prebiotics convert increase the solubility of iron, thereby enhancing its absorption. A total of 126 Sprague Dawley rats were fed with sixteen different types of fortified feed containing prebiotics (Inulin + Galacto Oligosaccharides) and Iron Fortificants (Sodium Ferric Ethylenediaminetetraacetate + Ferrous Sulphate).
