Five peptidomimetic prodrugs of didanosine (DDI) were synthesized and designed to improve bioavailability DDI following oral administration via targeting intestinal oligopeptide transporter (PepT1) enhancing chemical stability. The permeability was screened in Caco-2 cells grown on permeable supports. 5'-O-L-valyl ester prodrug (compound 4a) demonstrated the highest membrane selected as optimal target for further studies. uptake glycylsarcosine (Gly-Sar, a typical substrate PepT1) by could...

Most of the mortality resulting from COVID-19 has been associated with severe disease. Effective treatment cases remains a challenge due to lack early detection infection.This study aimed develop an effective prediction model for severity by combining radiological outcome clinical biochemical indexes.A total 46 patients (10 severe, 36 nonsevere) were examined. To build model, set 27 and 151 nonsevere laboratory records computerized tomography (CT) collected these patients. We managed extract...

Objective To explore the correlation between neutrophil-to-lymphocyte ratio (NLR) and contrast-induced acute kidney injury (CI-AKI). develop machine-learning (ML) methods based on NLR other relevant high-risk factors to establish new effective predictive models of CI-AKI. Methods: The data 2230 patients, who underwent elective vascular intervention, coronary angiography percutaneous intervention were retrospectively collected. patients divided into a CI-AKI group non-CI-AKI group. Logistic...

Objective: The aim of this case-control study was to analyze the association between sirtuin 1 (SIRT1) single nucleotide polymorphism (SNP) and risk acute kidney injury (AKI) in Han Chinese patients with cirrhosis explore its potential mechanism. Methods: Twenty-nine AKI (AKI group) 87 non-AKI (control were recruited from a population. SNaPshot sequencing technology used for detection SNPs. Dual luciferase reporter vectors constructed co-transfected into HK-2 human proximal tubular...

To evaluate the incidence, risk factors, and outcomes of acute kidney injury (AKI) in patients with decompensated cirrhosis based on Kidney Disease: Improving Global Outcomes Clinical Practice Guideline.For this retrospective analysis, 923 inpatients were recruited between January 2013 December 2017. The patients' baseline demographics clinical information collected analyzed. Univariate multiple logistic regression analyses conducted to determine independent factors for AKI in-hospital...
