Regulation of Sulfotransferase and UDP-Glucuronosyltransferase Gene Expression by the PPARs
Published 2009-01-01“…During phase II metabolism, a substrate is rendered more hydrophilic through the covalent attachment of an endogenous molecule. The cytosolic sulfotransferase (SULT) and UDP-glucuronosyltransferase (UGT) families of enzymes account for the majority of phase II metabolism in humans and animals. …”

Surface Enhanced Raman Spectroscopy of Proteins: Implications in Drug Designing
Published 2012-04-01“…Since its first observation in 1977, SERS have been fast developing into an analytical tool for trace detection of molecular entities, particularly in the area of bio‐molecule sensing and characterization. Also, with the development of the ability to design a variety of plasmonic structures and to be able to control and tune their plasmonic properties, we have been able to use them as SERS substrates for probing complex materials. …”

Micronutrients Considerations for Warm-Season Grass Systems in Florida
Published 2017-11-01“…An element can be considered essential for plant growth if a plant fails to complete its life cycle in the absence of the element, the elements action is specific and cannot be completely replaced by another element, it has a direct effect on the organism, or it is a constituent of a molecule that is known to be essential. The objective of this publication is to describe the role of micronutrients in warm-season grass production. …”

Psychrophilic Enzymes: From Folding to Function and Biotechnology
Published 2013-01-01“…In these naturally evolved enzymes, the optimization to low temperature activity is reached via destabilization of the structures bearing the active site or by destabilization of the whole molecule. This involves a reduction in the number and strength of all types of weak interactions or the disappearance of stability factors, resulting in improved dynamics of active site residues in the cold. …”

β-Endorphin Mediates the Development and Instability of Atherosclerotic Plaques
Published 2020-01-01“…The μ-opioid receptor (OPRM1) was expressed in THP-1 monocytes, macrophages, HASMCs, HUVECs, and human aortic endothelial cells. β-Endorphin significantly increased THP-1 monocyte adhesion to HUVECs and induced upregulation of intercellular adhesion molecule-1, vascular cell adhesion molecule-1, and E-selectin via nuclear factor-κB (NF-κB) and p38 phosphorylation in HUVECs. β-Endorphin significantly increased HUVEC proliferation and enhanced oxidized low-density lipoprotein-induced foam cell formation in macrophages. β-Endorphin also significantly shifted the macrophage phenotype to proinflammatory M1 rather than anti-inflammatory M2 via NF-κB phosphorylation during monocyte-macrophage differentiation and increased migration and apoptosis in association with c-jun-N-terminal kinase, p38, and NF-κB phosphorylation in HASMCs. …”
