Introduction: This study investigated low-density scalp electrical source imaging of the ictal onset zone and interictal spike ripple high-frequency oscillation networks using source coherence maps in the pediatric epilepsy surgical workup. Intracranial monitoring, the gold standard for determining epileptogenic zones, has limited spatial sampling. Source coherence analysis presents a promising new non-invasive technique.

In this study, a diffusive gradient in thin-films (DGT) passive sampling technique was developed for in situ monitoring of time-weighted average (TWA) concentrations of NNIs in groundwater and wastewater. Systematic studies demonstrated that DGT with HLB as binding gels (HLB-DGT) is suitable for quantitative sampling of NNIs under a wide range of conditions, independent of pH (5-9.

This study introduces a novel series of lipophilic HPTS derivatives, developed through a two-step synthesis route, designed as pH-sensitive dyes, characterized by high fluorescence intensity, photostability, dual excitation/single emission, and significant Stokes shifts. We engineered self-ratiometric pH-sensing planar optode foils and investigated the impact of carbon chain length on foil durability.

Methods: The Preferred Report Items for Systematic Reviews and Meta-Analysis Guidelines (PRISMA) were followed. We systematically searched MEDLINE, EMBASE and Cochrane databases up to December 2023 for original research articles on using CC to treat refractory ES.
Objectives: Abusive Head Trauma (AHT) remains an important cause of acute seizures, morbidity, and mortality in children. We aimed to assess the clinical and electrographic seizure burden in children with AHT and to explore predictors of morbidity and mortality.
Methods: We conducted a retrospective chart review of all children admitted with AHT who underwent continuous electroencephalographic monitoring (cEEG) between January 1st, 2015, and April 15th, 2021.
Tire wear particles (TWPs) containing tire wear chemicals (TWCs) are of global concern due to their large emissions and potential toxicity. However, TWP contributions to urban fine particles are poorly understood. Here, 72 paired gas-phase and PM samples were collected in the urban air of the Pearl River Delta, China.

In this study, a novel diffusive gradients in thin-film (DGT) technique based on molecularly imprinted polymers (MIPs) for selective measurement of a class of widely prescribed cardiovascular drugs (β-blockers) in wastewater was developed. The synthesized MIPs showed strong affinity and selectivity for the target compounds.

This study presents the first comprehensive assessment of HM levels in dry deposition and soils at proximity of forty (40) informal e-waste recycling sites across Pakistan, between September 2020 to December 2021. Findings reveal that Zn (1410), Pb (410) and Mn (231) exhibited the higher mean deposition fluxes (μg/m.

Soil organic matter is the main storage compartment for POPs in terrestrial ecosystems due to deposition and repeated air-surface exchange processes. Here, physicochemical properties and environmental factors were investigated for their role in influencing POPs accumulation in soils of the Tibetan Plateau and Antarctic and Arctic regions.

Conventional water sampling requires large water volumes, time-consuming pre-concentration and clean-up and is prone to analyte loss or contamination. Here, for the first time, we developed and validated a novel diffusive gradients in thin-films (DGT) passive sampler for PAHs.

Insufficient recognition of emissions and environmental contamination hamper global efforts to prevent antibiotic resistance development. This pioneering study combined empirical data and modeling approaches to predict total 2010-2020 emissions of 80 veterinary antibiotics ranging from 23,110 to 40,850 tonnes/year, after 36-50% antibiotic removal by manure treatment.

Sampling techniques capable of yielding information with high resolution are therefore needed to investigate chemical distributions and fluxes and to elucidate key processes affecting chemical fates. In this study, a high-resolution diffusive gradients in thin-films (DGT) technique was systematically developed and tested in a controlled sediment system to measure organic contaminants, antibiotics, for the first time.

This study utilizes a modeling approach to quantify for the first time national emissions and multimedia distributions of triphenyl phosphate (TPHP)─a well-known flame retardant─and three novel OPEs: tris(2,4-di-butylphenyl) phosphate (AO168═O), bis(2,4-di-butylphenyl) pentaerythritol diphosphate (AO626═O), and trisnonylphenol phosphate (TNPP). Emphasis is on the quantitative assessment of OPA source in China.

In addition to the physical impacts of macroplastics and microplastics on organisms, the chemical effects of plastic additives such as plasticisers have also received increasing attention. Research concerning plasticiser pollution in estuaries and coastal environments has been a particular focus, as these environments are the primary entry point for anthropogenic contaminants into the wider marine environment.

The availability of genetic testing has made it evident that monogenic and chromosomal abnormalities play an aetiological role in the development of EE/DEE-SWAS. We sought to review the literature to better understand the genetic landscape of EE/DEE-SWAS.

Methods: The principles of fundamental qualitative description guided this descriptive and exploratory qualitative study to document patients' and caregivers' perceptions and experiences. A purposeful sample of individuals (18 years or older) diagnosed with epilepsy or primary caregivers of PWE completed a single in-depth, semi-structured, one-to-one telephone interview.
Sudden unexpected death in epilepsy (SUDEP) is the leading cause of epilepsy-related death in children and adults living with epilepsy. Several recent clinical practice guidelines have recommended that all individuals living with epilepsy and their caregivers be informed about SUDEP as a part of routine epilepsy counseling. Furthermore, several studies over the last two decades have explored the state of SUDEP counseling.
