An Expanded Registry of Candidate cis-Regulatory Elements for Studying Transcriptional Regulation.

Mammalian genomes contain millions of regulatory elements that control the complex patterns of gene expression. Previously, The ENCODE consortium mapped biochemical signals across many cell types and tissues and integrated these data to develop a Registry of 0.9 million human and 300 thousand mouse candidate cis-Regulatory Elements (cCREs) annotated with potential functions.

High drug-loaded amorphous solid dispersions of a poor glass forming drug: The impact of polymer type and cooling rate on amorphous drug behaviour.

Enhancing the aqueous solubility via amorphization of crystalline poor glass-forming drugs represents a challenge, particularly when drug dosing is high. In such scenarios, there is often a need for high polymer loadings, leading to an increase in the dosage form mass and less patient acceptability. This work investigated the role that polymer type and after-melt cooling rate had upon the amorphicity of solid dispersions (SDs) containing high levels of naproxen and three commonly used polymeric excipients: Eudragit® EPO, Kollidon® VA64, and Soluplus®.

Comparison of Routine Preoperative Ultrasound-Guided Airway Examination Versus Clinical Airway Examination in Predicting Difficult Laryngoscopy in Patients Coming for Elective Surgery: An Observational Study.

Background As part of preoperative patient evaluations, it is customary to estimate the likelihood of difficulties during laryngoscopy and intubation. A diverse array of predictors is frequently employed by anesthesiologists to anticipate difficult laryngoscopy (DL); however, no single predictor has been established as the gold standard. In the present study, we compared routine preoperative ultrasound-guided airway examination and clinical airway examination in predicting DL in patients coming for elective surgery.

Spectroscopic and Thermal Characterisation of Interpenetrating Hydrogel Networks (IHNs) Based on Polymethacrylates and Pluronics, and Their Physicochemical Stability under Aqueous Conditions.

This study describes the physicochemical characterisation of interpenetrating hydrogel networks (IHNs) composed of either poly(hydroxyethylmethacrylate, p(HEMA)) or poly(methacrylic acid, p(MAA)), and Pluronic block copolymers (grades F127, P123 and L121). IHNs were prepared by mixing the acrylate monomer with Pluronic block copolymers followed by free radical polymerisation. p(HEMA)-Pluronic blends were immiscible, evident from a lack of interaction between the two components (Raman spectroscopy) and the presence of the glass transitions (differential scanning calorimetry, DSC) of the two components.

Hot Melt Extruded High-Dose Amorphous Solid Dispersions Containing Lumefantrine and Soluplus.

Over the last 15 years, a small number of paediatric artemisinin-based combination therapy products have been marketed. These included Riamet® and Coartem® dispersible tablets, a combination of artemether and lumefantrine, co-developed by the Medicines for Malaria Venture and Novartis. Disappointingly, patient compliance, requirement for high-fat meal, and sporadic drug dissolution behaviours following administration still result in considerable challenges for these products.
