Efficacy and Safety of Budesonide Orodispersible Tablets for Eosinophilic Esophagitis up to 3 Years: An Open-Label Extension Study.

Background & Aims: Budesonide orodispersible tablets (BOT) have been shown to be safe and effective in phase III double-blind trials of induction and 48-week maintenance therapy of eosinophilic esophagitis (EoE). We now analyzed the long-term efficacy and safety of BOT in a 96-week open-label extension (OLE) study.

Methods: All patients with EoE in the 48-week double-blind maintenance study were eligible to receive BOT treatment for up to 96 weeks.

An organoid-based CRISPR-Cas9 screen for regulators of intestinal epithelial maturation and cell fate.

Generation of functionally mature organs requires exquisite control of transcriptional programs governing cell state transitions during development. Despite advances in understanding the behavior of adult intestinal stem cells and their progeny, the transcriptional regulators that control the emergence of the mature intestinal phenotype remain largely unknown. Using mouse fetal and adult small intestinal organoids, we uncover transcriptional differences between the fetal and adult state and identify rare adult-like cells present in fetal organoids.

Functions of myosin motors tailored for parasitism.

Myosin motors are one of the largest protein families in eukaryotes that exhibit divergent cellular functions. Their roles in protozoans, a diverse group of anciently diverged, single celled organisms with many prominent members known to be parasitic and to cause diseases in human and livestock, are largely unknown. In the recent years many different approaches, among them whole genome sequencing, phylogenetic analyses and functional studies have increased our understanding on the distribution, protein architecture and function of unconventional myosin motors in protozoan parasites.

Cigar burning under different smoking intensities and effects on emissions.

The effect of smoking intensity on cigar smoke emissions was assessed under a range of puff frequencies and puff volumes. In order to potentially reduce emissions variability and to identify patterns as accurately as possible, cigar weights and diameters were measured, and outliers were excluded prior to smoking. Portions corresponding to 25%, 50%, 75% and 100% of the cigar, measured down to the butt length, were smoked under several smoking conditions, to assess nicotine, CO and water yields.

Emerging organic contaminants in vertical subsurface flow constructed wetlands: influence of media size, loading frequency and use of active aeration.

Four side-by-side pilot-scale vertical flow (VF) constructed wetlands of different designs were evaluated for the removal of eight widely used emerging organic contaminants from municipal wastewater (i.e. ibuprofen, acetaminophen, diclofenac, tonalide, oxybenzone, triclosan, ethinylestradiol, bisphenol A).
