Article Abstract
Objectives: To investigate relationships between blood styrene concentrations and neurobehavioral function among US Gulf State residents.
Methods: Our study includes 328 Gulf state residents enrolled in the Gulf Long-term Follow-up Study with data on blood styrene concentrations (2012-2013) and neurobehavioral test results (2014-2016, Behavioral Assessment and Research System and trail making test). We estimated the differences in test scores by blood styrene quartiles and explored effect measure modification by smoking.
Results: Styrene was detected in 77% of participants (median: 0.06 ng/ml). We observed only weak associations and no apparent dose-response relationships between styrene levels and performance on any neurobehavioral tests, although some associations were more prominent in males. For some neurobehavioral tests, we observed modestly stronger associations among participants with higher cotinine levels (>15 ng/mL).
Conclusion: We found limited support for an association between low-level blood styrene concentration and neurobehavioral test performance, although some associations were stronger among smokers.

Hyperkalemia is a common and serious complication in dialysis patients, with increased incidence and severity over time. Newer potassium binders, patiromer and sodium zirconium cyclosilicate (SZC), offer improved tolerability compared to older agents. This meta-analysis aims to evaluate the efficacy and safety of these newer binders in dialysis patients.

Organic photoelectrochemical transistor (OPECT) has emerged as a promising platform for investigating photoactive biomolecular interactions and advancing bioanalytical detection systems. However, many important challenges and hurdles remain implementing high gating effects and sensitive biosensing detection caused by the inherent limitations of the configuration of the photoelectrode structures and innovative biosensing. Inspired by the self-powered photoelectrochemical (PEC) systems and liposomes-assisted bioanalysis for signal amplification, a bipolar-driven poly(3,4-ethylenedioxythiophene): poly(styrene sulfonate) (PEDOT:PSS) OPECT based on CdS/Mixed Metal Metal-Organic Framework (MM-MOF) photoanode and a poly(1,4-diethynylbenzene) (pDEB) cathode is proposed, and exhibits a considerable current gain of ca.

Backgrounds: Microplastics (MPs) have been increasingly detected in human tissues, raising concerns about their role in cardiovascular disease. However, their distribution in matched blood and vascular tissues, such as atherosclerotic plaques, remains poorly understood.
Methods: Paired blood and carotid plaque samples were analyzed for 12 polymer types of MPs using pyrolysis-gas chromatography-mass spectrometry among twenty patients undergoing carotid endarterectomy.

Developing a drug delivery strategy that can cross the blood-brain barrier is crucial to effective neurological treatment. In this work, a new strategy was introduced for efficient drug delivery of Donepezil based on the preparation of polyelectrolyte complexes (PEC) nanogel from β-chitosan (CS) and the prepared sulfonated styrene-maleic anhydride (S-SMA). First, low-molecular-weight SMA was prepared.

Here, we present a copper-mediated magnetic molecularly imprinted polymer (Cu-mMIP) as dispersive solid-phase extracting material (dSPE) for fast, selective, and specific extraction of a metabolic biomarker vitamin B1 (VB1) in complex biological matrices. With emulsifier-free emulsion polymerization using styrene and itaconic acid as functional co-monomers, Cu as central atom, and FeO nanoparticles (NPs) as core, the resulted Cu-mMIP addresses VB1's structural challenges (conformational flexibility, hydrophilicity) while enabling rapid magnetic separation (< 10 s). The Cu-mMIP demonstrates exceptional specificity for VB1, achieving an imprinting factor of 5.
