The water-soluble ferriheme model FeIII(TPPS) mediates oxygen atom transfer from inorganic nitrite to a water soluble phosphine (tppts), dimethyl sulfide, and the biological thiols cysteine (CysSH) and glutathione (GSH). The products with the latter reductant are the respective sulfenic acids CysS(O)H and GS(O)H, although these reactive intermediates are rapidly trapped ...

On-surface synthesis is a promising approach for constructing covalently bound nanostructures. However, the number of reliable chemical reactions suitable for on-surface chemistry is very limited. Arylalkynes can be coupled at various surfaces in a novel 2D Glaser coupling. This approach can be used for constructing conjugated materials directly on surfaces.

Herein, we describe the use of thioglycosides as glycosidase inhibitors by employing novel modifications at the reducing end of these glycomimetics. The inhibitors display a basic galactopyranosyl unit (1→4)-bonded to a 3-deoxy-4-thiopentopyranose moiety. The molecular basis of the observed inhibition has been studied by using a combination of NMR spectroscopy ...

Metal-directed supramolecular construction represents one of the most powerful tools to prepare a large variety of structures and functions. The ability of metals to organize different numbers and types of ligands with a variety of geometries (linear, trigonal, octahedral, etc.) expands the supramolecular synthetic architecture. We describe here the precise ...

We studied the protective effect of stromal cell-derived factor-1beta (SDF-1β) on cardiac cells from lipotoxicity in vitro and diabetes in vivo. Exposure of cardiac cells to palmitate increased apoptosis by activating NADPH oxidase-associated nitrosative stress and endoplasmic reticulum (ER) stress, which abolished by pretreatment with SDF-1β via up-regulation of AMPK-mediated ...

Human embryonic stem cell (hESC) derived NK cells are a promising source of anti-tumor lymphocytes for off-the-shelf immunotherapeutics. They also provide a genetically tractable platform uniquely suited for study of anti-tumor immunotherapies in pre-clinical models. We have previously demonstrated the potency of hESC-derived NK cells in vivo. We have used ...

ABSTRACT: A 5-1/2-month-old female Holstein-Friesian calf was presented with a history of recurring ruminal tympany and poor development. The absence of lung sounds on the right hemithorax suggested a right-sided intrathoracic pathology. Radiography and computed tomography revealed a large thin-walled cavernous lesion with a gas-fluid interface which almost completely filled ...

Sleep-disordered breathing (SDB) constitutes a highly prevalent comorbidity in patients with chronic heart failure (HF, approximately 45 %). Both diseases are related in a bidirectional way: Obstructive sleep apnoea (OSA) can contribute to the development of HF via multiple mechanisms. Apnoea-related acute rise of cardiac afterload as well as manifest ...

ABSTRACT: Bronchial obstruction due to a tumor embolus of the contralateral lung during pneumonectomy is an uncommon and fatal complication. According to previous cases, a bronchial balloon of double-lumen endotracheal tube (DLT) could prevent a dislodged tumor from traveling to the contralateral lung. We experienced a tumor embolism from the ...

Gastrointestinal mechanisms involved in the suppression of appetite are compromised in obesity. Glucagon-like peptide-1 (GLP-1) is released in response to nutrients, suppresses food intake, and has been shown to play a role in regulation of energy balance. It is not known whether obese-prone (OP) rats exhibit dysfunctional GLP-1 signaling that ...
