Tobacco smoke exposure and mitochondrial DNA copy number on neurobehavioural performance: A community study.

The influence of tobacco smoke has been a controversial and very questionable subject within the field of neurological behaviours. To examine the dose-response relationships between tobacco smoke and neurological performance, we investigated whether mitochondrial DNA copy number (mtDNAcn) mediates these relationships. We used restricted cubic spline models to estimate the dose-response relationships.

Physicochemical, antioxidant properties of giant croaker (Nibea japonica) swim bladders collagen and wound healing evaluation.

Acid-solubilized collagen (ASC) and pepsin-solubilized collagen (PSC) were obtained from Nibea japonica swim bladders. The denaturation temperature (Td) of ASC and PSC was approximately 33.8 °C.

Collagen Extracted from Bigeye Tuna () Skin by Isoelectric Precipitation: Physicochemical Properties, Proliferation, and Migration Activities.

Collagen was extracted from bigeye tuna () skins by salting-out (PSC-SO) and isoelectric precipitation (PSC-IP) methods. The yield of the PSC-IP product was approximately 17.17% (dry weight), which was greater than the yield obtained from PSC-SO (14.

On the Stability of NaO in Na-O Batteries.

Na-O batteries are regarded as promising candidates for energy storage. They have higher energy efficiency, rate capability, and chemical reversibility than Li-O batteries; in addition, sodium is cheaper and more abundant compared to lithium. However, inconsistent observations and instability of discharge products have inhibited the understanding of the working mechanism of this technology.

Towards an Understanding of Li O Evolution in Li-O Batteries: An In Operando Synchrotron X-ray Diffraction Study.

One of the major challenges in developing high-performance Li-O batteries is to understand the Li O formation and decomposition during battery cycling. In this study, this issue was investigated by synchrotron radiation powder X-ray diffraction. The evolution of Li O morphology and structure was observed under actual electrochemical conditions of battery operation.

Enhancing clostridial acetone-butanol-ethanol (ABE) production and improving fuel properties of ABE-enriched biodiesel by extractive fermentation with biodiesel.

The extractive acetone-butanol-ethanol (ABE) fermentations of Clostridium acetobutylicum were evaluated using biodiesel as the in situ extractant. The biodiesel preferentially extracted butanol, minimized product inhibition, and increased production of butanol (from 11.6 to 16.
