Grain-Surface Hydrogen-Addition Reactions as a Chemical Link Between Cold Cores and Hot Corinos: The Case of HCCS and CHCHSH.

Recently, searches were made for HCCS and HCCSH in a variety of interstellar environments─all of them resulted in nondetections of these two species. Recent findings have indicated the importance of destruction pathways, e.g.

Mindfulness-Based Stress Reduction in Breast Cancer Survivors with Chronic Neuropathic Pain: A Randomized Controlled Trial.

Objectives: The purpose of this study was to compare the effects of group-delivered mindfulness-based stress reduction as compared to a waitlist control group among breast cancer survivors living with CNP.

Methods: A randomized controlled trial design was applied, and outcomes collected included pain, emotional function, quality of life, and global impression of change.

Results: A total of 98 women were randomized and included in analyses.

Efficient Labeling of Nanocellulose for High-Resolution Fluorescence Microscopy Applications.

The visualization of naturally derived cellulose nanofibrils (CNFs) and nanocrystals (CNCs) within nanocomposite materials is key to the development of packaging materials, tissue culture scaffolds, and emulsifying agents, among many other applications. In this work, we develop a versatile and efficient two-step approach based on triazine and azide-alkyne click-chemistry to fluorescently label nanocelluloses with a variety of commercially available dyes. We show that this method can be used to label bacterial cellulose fibrils, plant-derived CNFs, carboxymethylated CNFs, and CNCs with Cy5 and fluorescein derivatives to high degrees of labeling using minimal amounts of dye while preserving their native morphology and crystalline structure.

An interdisciplinary program for familiar faces with chronic pain visiting the emergency department-randomized controlled trial.

Objectives: To evaluate the effect of a collaborative interdisciplinary pain assessment program on pain and health-related quality of life among individuals with chronic pain who frequently visit the emergency department (ED).

Methods: Individuals with chronic pain who frequented the ED (ie, ≥8 visits within the previous 12 months) were randomly assigned to a collaborative chronic pain management program or treatment as usual. Primary outcomes were change in physical function and visits to the ED from baseline to 12 months using validated measures.

Structures, Phase Behavior, and Fluorescent Properties of 3-Phenyl-1-(pyridin-2-yl)-1-pyrazol-5-amine and Its ZnCl Complex.

The synthesis of the asymmetric ligand 3-phenyl-1-(pyridin-2-yl)-1-pyrazol-5-amine () and its single-crystal X-ray structure are reported. displays crystallographic symmetry (orthorhombic, ) higher than its molecular symmetry (point group ) and also displays supercooling, with a difference in the melting and solidification points of over 100 °C. Upon complexation with ZnCl, engages in both primary cation and secondary anion coordination via hydrogen bonding, and the complex exhibits a room-to-low-temperature single crystal-to-crystal phase transition.
