Front Cover: In article number 2100336 by Akikazu Matsumoto and co-workers, RAFT polymerization of the BOC-protected 2-hydroxyethyl methacrylate was carried out to control molecular weight, polydispersity, chain-end groups, sequence structure block copolymers. The hydroxy-containing polymers produced acid-catalyzed deprotection were converted precursors for a thermally curing polymer network sy...

BACKGROUND AND PURPOSE Regular exercise can result in changes in the levels of oxidative stress in the hippocampus; however, little attention has been paid to physical-activity-induced neuronal protection to exposure to lead compounds. This study investigated the effects of regular treadmill exercise on a DNA oxidative-damage marker [8-hydroxy-2'-deoxyguanosine (8-OHdG)] and the total antioxida...

Abstract Abiu ( Pouteria caimito ) is one of the exotic plants native to Amazon and has been introduced in Indonesia. contained beneficial compounds for health. Therefore, hexane extract from several parts abiu were identified its volatile compound content. The study used 6 (six) plant, i.e. shoot leaves, mature unripe fruit, ripe fruit pulp, peel seed. contents determined using gas chromatogra...

Warm ischemia-reperfusion injury remains a crucial issue in transplantation following the cardiac death of donors. Previously, we showed that surfactant inhalation during warm ischemia mitigated ischemia-reperfusion injury. This study investigated the mechanisms of surfactant inhalation protection of the warm ischemic lung after reoxygenation with ventilation alone. In an isolated rat lung vent...

Vacuum ultraviolet （VUV） irradiation was applied to photo-activation bonding of polyoxymethylene （POM） plates. The photo-activated POM plates were bonded directly below the melting point. Their VUV-irradiated surfaces analyzed using X-ray photoelectron spectroscopy （XPS） and Fourier transform infrared （FTIR）. Results these analyses suggest that VUV introduced hydroxy groups through oxidation, m...

Atomistic computer simulation techniques were employed to investigate the interaction of a selection of organic surfactant molecules with different surface features of the calcium fluoride {111} surface. The adsorbates coordinate mainly to the surface through interaction between their oxygen (or nitrogen) atoms to surface calcium ions, followed by hydrogen-bonded interactions to surface fluorid...

Ceramides with mono-, di-, and trihydroxy long-chain bases, and normal (saturated and unsaturated), branched-chain, and 2-hydroxy fatty acids have been analyzed by thin-layer chromatography. In most cases the compounds were also run as acetates. Borate, arsenite, and silver ions were used as complexing agents, and the effects of number, position, and stereochemistry of hydroxy groups, and of un...

The marine sponges (Porifera) are a unique group of sedentary organisms from which several novel natural products are reported, many of which have useful biological activities. In producing unusual sterols, they occupy a preeminent position among the various groups of organisms. The polar sterols of sponges reported as at the end of the year 2002 number about 250; their ring structure changing ...
