Published: September 2016

Hydrogen release from Al-based complex hydrides composed of metal cation(s) and [AlH] was investigated using inelastic neutron scattering viewed from vibrational dynamics. The hydrogen release followed the softening of translational and [AlH] librational modes, which was enhanced by vibrational dynamics and the valence(s) of the metal cation(s).

Supramolecular oleogels, in which low-molecular weight oleogelators self-assemble into various nanostructures through non-covalent interactions, have witnessed increasing research activity in various fields of science, including food, cosmetics or remediation of marine oil spills. Herein, we report a simple scalable and environmentally friendly carbohydrate-based oleogelator, namely, the sodium salt of ,'-dimethyl β- glucosyl barbiturate (GlcBMe) that self-assembles through sonication to induce the gelation of polar organic solvent and later of non-polar vegetable oils by cationic exchange with quaternary ammonium surfactants. Water-soluble GlcBMe was capable of forming self-assembled fibrillar network bridging insoluble particles in the oil by sonication in the presence of a small amount of water.

With the progress of atherosclerosis (AS), the arterial lumen stenosis and compact plaque structure, the thickening intima and the narrow gaps between endothelial cells significantly limit the penetration efficiency of nanoprobe to plaque, weakening the imaging sensitivity and therapy efficiency. Thus, in this study, a HO-NIR dual-mode nanomotor, Gd-doped mesoporous carbon nanoparticles/Pt with rapamycin (RAPA) loading and AntiCD36 modification (Gd-MCNs/Pt-RAPA-AC) was constructed. The asymmetric deposition of Pt on Gd-MCNs catalyzed HO at the inflammatory site to produce O, which could promote the self-motion of the nanomotor and ease inflammation microenvironment of AS plaque.

Engine Testing Laboratory, Department of Automobile Engineering, College of Engineering and Technology, SRM Institute of Science and Technology, Kattankulathur, 603203, Tamil Nadu, India.

The present work emphasizes the viability of methyl ester production, characterization, and utilization of third-generation biofuel from Chlorella vulgaris microalgae. The presence of methyl oleate (CHO) in the Chlorella vulgaris methyl ester (CVME) algae signifies the existence of higher oxidation stability and prone to peroxidation. The single-stage transesterified CVME algae contains majorly (C-H) functional group trailed by (C = O), (C-O), (O-CH), (C-O-C) with the elemental compositions of 66.

Vasoplegia in Heart, Lung, or Liver Transplantation: A Narrative Review.

Department of Anesthesia, Critical Care, and Pain Medicine, Massachusetts General Hospital, Boston, MA.

Vasoplegia is a pathophysiologic state of hypotension in the setting of normal or high cardiac output and low systemic vascular resistance despite euvolemia and high-dose vasoconstrictors. Vasoplegia in heart, lung, or liver transplantation is of particular interest because it is common (approximately 29%, 28%, and 11%, respectively), is associated with adverse outcomes, and because the agents used to treat vasoplegia can affect immunosuppressive and other drug metabolism. This narrative review discusses the pathophysiology, risk factors, and treatment of vasoplegia in patients undergoing heart, lung, and liver transplantation.

Synergistic therapy with celastrol-curcumin multifunctional nanomedicine: Anti-hepatocellular carcinoma and reduced hepatotoxicity.

Int J Pharm

State Key Laboratory of Southwestern Chinese Medicine Resources, School of Pharmacy, Chengdu University of Traditional Chinese Medicine, Chengdu 611137 China. Electronic address:

Hepatocellular carcinoma is one of the leading causes of cancer deaths globally and a key hindrance to extending life expectancy. Celastrol (CEL) demonstrates excellent antitumor activity, but faces challenges like low solubility and a narrow therapeutic window, limiting its clinical application. To address these limitations, drug combinations and nano-delivery systems have emerged as effective solutions.
