Protective effect of unsaturated fatty acids on cognitive impairment in CKD patients: Results from the National Health and Nutrition Examination Survey (2011-2014).

Background: It is still unknown whether unsaturated fatty acids (UFA) have the same effect on preventing cognitive impairment in chronic kidney disease (CKD) patients as in healthy people.

Objective: To investigate the protective effect of dietary UFA intake and proportion on cognitive impairment in patients with CKD.

Methods: We extracted data from the National Health and Nutrition Examination Survey (NHANES, 2011-2014) on participants with a previous diagnosis of CKD and at least one complete cognitive assessment (Consortium to Establish a Registry for Alzheimer's Disease test, Animal Fluency Test and Digit Symbol Substitution Test).

Trends in the Analysis and Exploration of per- and Polyfluoroalkyl Substances (PFAS) in Environmental Matrices: A Review.

Per- and polyfluoroalkyl substances (PFAS) is an emerging class of organic pollutants of concern and is now prevalent in environmental matrices including water, soil, air, and biological. So far, several standard analytical methods have been developed to systematically analyze PFAS in different environmental matrices. However, the complexity of environmental matrices makes the effective extraction of PFAS difficult, and the legacy PFAS is gradually changing into a new PFAS with short chain and unknown structure in production, which makes the analysis of PFAS challenging.

Hydrochar coupled with iodide for efficient photodegradation of perfluorooctanoic acid and perfluorooctane sulfonic acid under ultraviolet light.

Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) are typical emerging persistent organic pollutants that are raising concerns regarding their environmental persistence. The photodegradation of these chemicals in water can be promoted by generating hydrated electrons (e). The present work demonstrates a highly efficient process combining ultraviolet (UV) radiation, hydrochar (H-BC) and KI that is capable of decomposing PFOA and PFOS.
