The synthesis of new silylethyne-substituted hexacene derivatives to investigate their solubility, stability, and pi-stacking is reported. It was found that "butterfly" dimerization, rather than photooxidation, is the dominant decomposition pathway for these molecules and that stability can be enhanced by functionalization to prevent close contact between specific regions of the aromatic core. ...

This article reviews the application of transient techniques in the elucidation of electron, proton and photon chemistry related to the catalytic subsite of [FeFe]-hydrogenase from the perspective of research in this area carried out at the UEA and Strathclyde laboratories. The detection of mixed valence states, bridging CO intermediates, paramagnetic hydrides and coordinatively unsaturated spe...

Objective(s)Distinction of hydatidiform moles from non-molar specimens and subclassification of hydatidiform moles as complete and partial are important for clinical practice, but diagnosis based solely on histomorphology suffers from poor interobserver reproducibility. Nowadays, pathologists rely on molecular techniques, however these methods are technically difficult, relatively expensive, an...

Fusion-based imaging using ground-penetrating radar (GPR) and ultrasonic echo array (UEA) was employed to track damage progression in the columns of two full-scale reinforced concrete (RC) bridge column-footing subassembly laboratory specimens. The specimens had different lap-splice detailing were subjected reverse-cyclic lateral loading simulating a subduction zone earthquake. GPR UEA scans pe...

In the context of Internet Things (IoT), proliferation identity spoofing threats has led to need for constant entity verification devices. Recently, a formal framework been proposed study resistance impersonation attacks One-Message Unilateral Entity Authentication (OM-UEA) schemes, in which prover continuously authenticates itself through use sequence authentication messages. Given limited com...

BACKGROUND Hydatidiform moles carry a significant risk for developing persistent gestational trophoblastic disease. Lectins are useful tools to identify cellular glycosylation pattern and changes in glycosylation that occur during growth, development, differentiation and also, during disease states. OBJECTIVES Considering the changes in glycosylation that occur during cell proliferation, diff...

INTRODUCTION The aim of this study was to compare fucose and sialic acid residue expression on fibronectin and α{1}-acid glycoprotein in the seminal plasma of men suspected of infertility and suffering from leukocytospermia. SUBJECTS AND METHODS Seminal ejaculates were collected from 27 leukocytospermic and 18 healthy, normozoospermic men. The relative degree of fucosylation and sialylation o...

A class of monoorganoimido-substituted hexamolybdates containing a pyridine group have been firstly synthesized. Furthermore, a reaction protocol of alkylation based on the resulting pyridine-functionalized hexamolybdates has been developed, with which a type of zwitterionic clusters has been successfully obtained.
