Kinetics of Alkoxysilanes and Organoalkoxysilanes Polymerization: A Review
Polymers, 2019 Scientists from various different fields use organo-trialkoxysilanes and tetraalkoxysilanes in a number of applications. The silica-based materials are sometimes synthesized without a good understanding of the underlying reaction kinetics.

FEBS Letters, EarlyView.C‐mannosylation is a unique form of protein glycosylation. In this study, we demonstrated that ADAMTS1 is C‐mannosylated at Trp562 and Trp565 in human testicular germ cell tumor NEC8 cells. We found that C‐mannosylation of ADAMTS1 is essential for its secretion, processing, enzymatic activity, and ability to promote vasculogenic mimicry. These findings

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes
FEBS Letters, EarlyView.Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Effective Polymer Dynamics of D-Dimensional Black Hole Interiors [PDF]
, 2009 We consider two different effective polymerization schemes applied to D-dimensional, spherically symmetric black hole interiors. It is shown that polymerization of the generalized area variable alone leads to a complete, regular, single-horizon spacetime

Vinyl Polymerization. XLVIII. Polymerization of Methylstyrenes and the Effect of Dimethylaniline on their Polymerization [PDF]
Bulletin of the Chemical Society of Japan, 1961 Abstract 1. Solution polymerizations of styrene, p-methyl-, p-ethyl-, p-tert-butyl-, m-methyl-, 2,4-dimethyl-, 2,5-dimethyl- and 3,4-dimethylstyrene were carried out at 50 and 70°C by ABIN in benzene, and the rates of polymerization and [η]’s of the polymers were determined.

FEBS Letters, EarlyView.Nicotinamide (NIC) and nicotinic acid (NIA) are proposed as stress signaling compounds in plants. Oxidative stress may lead to single strand breaks (SSB) in DNA, which activate poly(ADP‐ribose) polymerase (PARP). NIC and NIA are then formed from NAD. NIC and NIA can promote epigenetic changes leading to the expression of defense genes specific for the ...
