Combined Cell-Free DNA Screening for Aneuploidies and Selected Single-Gene Disorders for Pregnancies With Sonographically Detected Fetal Anomalies: Detection Rate and Residual Risk.

Objectives: To determine the additional detection rate (DR) and the residual risk (RR) of combined cell-free DNA (cfDNA) screening for aneuploidies (not including copy number variants) and 25 dominant single-gene disorders (SGD) in pregnancies with sonographic abnormalities.

Method: One hundred sixteen singleton pregnant women with abnormal fetal ultrasounds from week 12 were included in the study. They underwent combined cfDNA analysis, while exome sequencing and karyotyping were performed as reference standards.

Ionic liquids and their potential use in development and improvement of drug delivery systems: evidence of their tendency to promote drug accumulation in the brain.

Ionic liquids (ILs) are considered salt in liquid state, which is composed of organic cations and anions with low melting points (<100 °C). ILs have become a major scientific area with an extensive range of applications including chemistry, electrochemistry, and pharmaceutics. ILs have received great research interest in the pharmaceutical field as solvents, anti-solvents, co-solvents, and reagents in synthesis and formulation.

Dietary fiber content in clinical ketogenic diets modifies the gut microbiome and seizure resistance in mice.

The gut microbiome is emerging as an important modulator of the anti-seizure effects of the classic ketogenic diet. However, many variations of the ketogenic diet are used clinically to treat refractory epilepsy, and how different dietary formulations differentially modify the gut microbiome in ways that impact seizure outcome is poorly understood. We find that clinically prescribed ketogenic infant formulas vary in macronutrient ratio, fat source, and fiber content and also in their ability to promote resistance to 6-Hz psychomotor seizures in mice.

Quorum sensing inhibiting dihydropyrrol-2-ones embedded polymer/graphene oxide nanocomposite waterborne antimicrobial coatings.

With increasing antibiotic resistance and hospital acquired microbial infections, there has been a growing interest to explore alternate antimicrobial approaches. This is particularly challenging when aiming to protect surfaces over a large area to avoid contact mediated infection transmission. Quorum sensing (QS) inhibition has emerged as an alternate antimicrobial approach overcoming evolutionary stress driven resistance observed in antibiotic treatment.
