There is growing interest in generating in vitro models of tissues and tissue-related diseases to mimic normal tissue organization and pathogenesis for different purposes. The retina is a highly complex multicellular tissue where the organization of the cellular components relative to each other is critical for retinal function. Many retinopathies arise due to the disruption of this order.

Background: Narcolepsy, a central hypersomnolence disorder, disrupts sleep regulation. Sodium oxybate, a CNS (central nervous system) depressant, is widely used as a treatment, but there are surprisingly very few rigorous studies comparing its effectiveness to placebo in adults.

Objectives: To measure the comparative efficacy of sodium oxybate at a dosage regimen of 9 g versus placebo in improving nighttime sleep quality, reducing nocturnal arousals and sleep stage shifts, and enhancing the overall refreshed nature of sleep in adult patients with narcolepsy.

Hydrate-based carbon capture and storage (HBCS) is a sustainable and promising approach to combating global warming by utilizing water, which is a ubiquitous resource. Here, we report a comprehensive study of CO hydrate formation in dry water (DW), a water-in-air dispersion confined in silica particles, for improving the kinetics of hydrate growth. Utilizing a combination of a home-built high-pressure reactor, in situ Raman spectroscopy, and powder X-ray diffraction (PXRD), we elucidate the crystal structure, growth dynamics, and morphology of CO hydrates formed in DW, with and without the kinetic hydrate promoter, l-tryptophan.

: Barrett's esophagus (BE), with metaplastic columnar epithelium in the lower esophagus, predisposes patients to esophageal adenocarcinoma (EAC). Despite extensive research, mechanisms underlying BE progression to EAC remain unclear, and no validated biomarkers are available for clinical use. Progastricsin/Pepsinogen-C (PGC), an aspartic proteinase linked to maintaining normal epithelial morphology, is often absent in advanced gastrointestinal malignancies.
