A proinflammatory cytokine interleukin-6 (IL-6) plays an important role in the development, pathogenesis and outcome of SIRS, sepsis and septic shock. We have evaluated the role of the IL-6 gene polymorphisms in pediatric patients. A total of 421 consecutive pediatric patients admitted to the pediatric intensive care unit with fever, systemic inflammatory response syndrome (SIRS), sepsis, severe sepsis, septic shock, or multiple organ distress syndrome (MODS) were studied together with 644 healthy controls. DNA was isolated and two IL-6 gene polymorphisms (G-174>C and G-572>C) were analyzed. The frequencies of both analyzed variants differ significantly between the group of patients and healthy controls (p = 0.02 for G-174>C and p = 0.049 for G-572>C). In addition, genetic analysis of the G-174>C IL-6 gene variant revealed significant differences between the subgroup of febrile patients and subgroup of septic shock (p = 0.0319) and between the subgroup of SIRS and septic shock (p = 0.038). In both cases the negative genotype was CC. No statistically significant differences for the IL-6 gene polymorphism G-572>C were found between the groups of patients with different diagnosis. IL-6 gene polymorphisms G-174>C and G-572>C could be the predictors of risk of development and/or the predictors of the severity of sepsis in children.

Myocardial infarction (MI) is a leading cause of morbidity and mortality worldwide, and mitigating oxidative stress is crucial in managing MI. Nuclear factor erythroid 2-related factor 2 (Nrf2) plays a critical role in combating oxidative stress and facilitating cardiac remodeling post-MI. Here, we engineered Cerium oxide (CeO) nanoparticle-guided assemblies of ceria/Nrf2 nanocomposites to deliver Nrf2 plasmids.

Despite considerable advances in identifying risk factors for obesity development, there remains substantial gaps in our knowledge about its etiology. Variation in obesity (defined by BMI) is thought to be due in part to heritable factors; however, obesity-associated genetic variants only account for a small portion of heritability. Epigenetic regulation, defined by genetic and/or environmental factors with changes in gene expression, may account for some of this "missing heritability".

Clonal hematopoiesis of indeterminate potential (CHIP) is associated with increased mortality and malignancy risk, yet the determinants of clonal expansion remain poorly understood. We performed sequencing at >4,000x depth of coverage for CHIP mutations in 6,986 postmenopausal women from the Women's Health Initiative at two timepoints approximately 15 years apart. Among 3,685 mutations detected at baseline (VAF ≥ 0.

Background: Vitamin D (VD) deficiency and insulin resistance (IR) increase the risk of non-alcoholic fatty liver disease (NAFLD), but few studies have explored the potential mechanisms by which IR mediates the association between VD and the pathogenesis of NAFLD at the genetic level using publicly available databases.

Methods: This is a cross-sectional study, and we utilized the National Health and Nutrition Examination Survey (NHANES) dataset, as well as data from GSE200765 obtained from the Gene Expression Omnibus (GEO) website. A total of 723 individuals who had completed liver ultrasound examination and the detection of VD levels were included in the final analysis.
