A Rare Case of Nitroglycerin Resistant Coronary Arterial Vasospasm During Coronary Artery Bypass Surgery

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Coronary artery vasospasm following coronary artery bypass grafting (CABG) is a rare but potentially life‐threatening complication that can lead to myocardial ischemia, arrhythmias, and cardiogenic shock. Nitroglycerin‐resistant vasospasm, particularly involving the left main coronary artery (LMCA), poses significant diagnostic and ...

An Efficient Thiol‐ene Mediated Protocol for Thiolated Peptide Synthesis and On‐Resin Diversification

open access: yesChemistry – A European Journal, EarlyView.
Herein, a sequential acyl‐thiol‐ene/S‐deacetylation protocol for selective installation of thiol residues onto synthetic peptides, on‐resin, is demonstrated. The hydrothiolation/S‐deacetylation protocol offers a novel synthetic tool for direct peptide conjugation on‐resin and for the preparation of novel disulfide containing neuropeptides displaying ...

Harnessing Viral Proteases for Cellular and Molecular Engineering

open access: yesChemistry–Methods, EarlyView.
Engineered viral proteases (VIPs) provide programmable control of protein function with high specificity and low toxicity. Integrated with chemogenetic and optogenetic modules, these VIP systems enable logic gate manipulation for targeted regulation of cell signaling, gene expression, protein secretion, and degradation, thereby offering versatile ...

Epitaxy and Topotaxy in the Aragonite‐Calcite Polymorphism

open access: yesCrystal Research and Technology, EarlyView.
At first distinguish epitaxy from topotaxy, which rule the main mechanisms of calcite‐aragonite transitions. Then, attempt to move from qualitative to quantitative descriptions of these transitions. Hence, it will deal with 2D (epitaxy) and 3D (topotaxy) conversions in the polymorphic system, in order to gain insight on their differences.

A Simple Strategy for Co‐Immobilization of NADH‐Dependent Enzymes and NADH for Efficient Biocatalysis in Continuous Flow Reactors

open access: yesChemSusChem, EarlyView.
Polyethylenimine‐modified Cry3Aa‐formate dehydrogenase (FDH)/Cry3Aa‐leucine dehydrogenase (LDH) fusion particles entrapped in agarose beads enables efficient NADH recycling, thereby facilitating the continuous synthesis of chiral intermediates in a flow reactor.

Gene regulation of vasopressin and vasopressin receptors in cancer

open access: yesExperimental Physiology, 2000
It is proposed that neuropeptide production by tumours is an important part of a special process of oncogenic transformation rather than a pre‐existing condition of progenitor cells; this concept is called Selective Tumour gene Expression of Peptides essential for Survival (STEPS).

Combining photocatalytic oxidation of β‐chlorohydrins with carbonyl bioreduction in a deracemization approach

open access: yesChemSusChem, Accepted Article.
Enantiopure β‐chlorohydrins are valuable intermediates in organic synthesis, acting as chiral building blocks for obtaining biologically active compounds. This work presents a one‐pot two‐step linear sequence for the efficient deracemization of β‐chlorohydrins by combining a photocatalytic alcohol oxidation with a stereoselective carbonyl bioreduction ...
