Davydov Split Aggregates of Cyanine Dyes on Self-Assembled Nanotubes.

The Davydov splitting of dye aggregates represents unique molecular excitons. In this paper, e report the formation of Davydov split aggregates of 3,3'-diethylthiacarbocyanine iodide (DiSC (3)) and 3,3'-diethylthiadicarbocyanine iodide (DiSC (5)) templated by the helical nanotubes of lithocholic acid (LCA). The templated Davydiv split aggregates show a strong J-band and a weak H-band in the adsorption spectra.

Colorimetric Detection of Dopamine with J-Aggregate Nanotube-Integrated Hydrogel Thin Films.

The deficiency of dopamine (DA) is clinically linked to several neurological diseases. The detection of urinary DA provides a noninvasive method for diagnosing these diseases and monitoring therapies. In this paper, we report the coassembly of lithocholic acid (LCA) and 3,3'-diethythiadicarbocyanine iodide (DiSC(5)) at the equimolar ratio in ammonia solution into J-aggregate nanotubes.

Soft-Templated Synthesis of Lightweight, Elastic, and Conductive Nanotube Aerogels.

Conductive polymer (CP) nanotubes are fascinating nanostructures with high electrical conductivity, fast charge/discharge capability, and high mechanical strength. Despite these attractive physical properties, progress in the synthesis of CP nanotube hydrogels is still limited. Here, we report a facile and effective approach for the synthesis of polypyrrole (PPy) nanotube hydrogels by using the weakly interconnected network of self-assembled nanotubes of lithocholic acid as a soft template.

Formation of Spherulitic J-Aggregates from the Coassembly of Lithocholic Acid and Cyanine Dye.

Supramolecular aggregates of organic dyes through noncovalent interactions have attracted great interest because they exhibit collective optical and excitonic properties. We report the formation of spherulitic J-aggregates from the coassembly of lithocholic acid (LCA) and 3,3'-diethylthiacarbocyanine iodide (DiSC(3)) in ammonia solution. Each spherulite contains a core, which serves as a nucleus for the growth of radially oriented J-aggregate fibrils.

A prospective single-institution evaluation of current practices of early postoperative feeding after elective intestinal surgery.

Postoperative diet advancement in patients undergoing elective small bowel or colorectal surgery by general surgeons (GSs) and colorectal surgeons (CRSs) was prospectively evaluated. Demographic (age and gender), disease location (small bowel or colorectum), surgical approach (laparoscopic or open), and surgeon characteristics (GS or GRS) were tabulated. Postoperative feeding after surgery on postoperative Day (POD) 1 was assessed.
