To better understand the characterization and secondary organic aerosol (SOA) formation of volatile organic compounds (VOCs) during non-haze and haze days, ambient VOCs were continuously measured by a vehicle-mounted online thermal desorption system coupled with a gas chromatography-mass spectrometry (TD-GC/MS) system in Shanghai, China. The average concentrations of VOCs in haze episodes (193.2 μg m(-3)) were almost 50% higher than in non-haze periods (130.8 μg m(-3)). VOC concentrations exhibited a bi-modal pattern in the morning and evening rush hour periods on both non-haze and haze days...

The synthesis of thermoset shape memory polymer (SMP) polyurethanes from symmetric, aliphatic alcohols and diisocyanates has previously demonstrated excellent biocompatibility in short term in vitro and in vivo studies, although long term stability has not been investigated. Here we demonstrate that while rapid oxidation occurs in these thermoset SMPs, facilitated by the incorporation of multi-functional, branching amino groups, byproduct analysis does not indicate toxicological concern for these materials...

Fungal aromatic polyketides display a very diverse and widespread group of natural products. Due to their excellent light absorption properties and widely studied biological activities, they offer numerous application for food, textile and pharmaceutical industry. The biosynthetic pathways of fungal aromatic polyketides usually involve a set of successive enzymes, in which a non-reductive polyketide synthases iteratively catalyzes the essential assembly of simple building blocks into (often polycyclic) aromatic compounds...

Corynebacterium glutamicum serves as important production host for small molecular compounds that are derived from precursor molecules of the central carbon metabolism. It is therefore a well-studied model organism of industrial biotechnology. However, a deeper understanding of the regulatory principles underlying the synthesis of central metabolic enzymes under different environmental conditions as well as its impact on cell growth is still missing. We studied enzyme abundances in C. glutamicum in response to growth on: i) one limiting carbon source by sampling chemostat and fed-batch cultivations and ii) changing carbon sources provided in excess by sampling batch cultivations...

Viral infections are a major burden to human and animal health. Immune response against viruses consists of innate and adaptive immunity which are both critical for the eradication of the viral infection. The innate immune system is the first line of defense against viral infections. Proper innate immune response is required for the activation of adaptive, humoral and cell-mediated immunity. Macrophages are innate immune cells which have a central role in detecting viral infections including influenza A and human immunodeficiency viruses...

In an effort to explore the residual complexity of naturally occurring chalcones from the roots of Glycyrrhiza inflata (Fabaceae), two new licochalcone A (LicA) derivatives were isolated as trace metabolites from enriched fractions. Both constituents contain a dihydrofuran moiety linked to carbons C-4 and C-5 of the retrochalcone core. Compound 1 (LicAF1) represents a new chemical entity, whereas compound 2 (LicAF2) has previously been reported as a Lewis acid catalyzed rearrangement of LicA. Evaluation of chirality revealed that both dihydrofuran derivatives existed as a mixture of R and S enantiomers...

Phytochemical investigation of the roots of Salvia miltiorrhiza led to isolations of two new depsides (1-2), along with thirteen known compounds (3-15). Their structures and relative stereochemistry were elucidated by NMR spectral ((1)H and (13)C NMR, HSQC, HMBC), CD and HR-ESIMS data analyses. The absolute configuration of 1 was determined by comparison of the experimental and calculated ECD spectra. All the depsides (1-10) were found to exhibit stronger free radical scavenging capacity (ranging from 2.62 to 22...

The dysregulated proliferation, migration, apoptosis and angiogenesis of endothelial cells are involved in diabetic endothelial dysfunction. The circulating salusin-β levels were increased in diabetic patients, and salusin-β contributes to diabetic cardiomyopathy in rats. However, the roles of salusin-β in diabetes mellitus-induced endothelial dysfunction are not fully understood. Herein, we demonstrated the increased expressions of salusin-β in human umbilical vein endothelial cells (HUVECs) cultured in HG medium...

Inhibitor of Apoptosis Proteins (IAPs) are critical regulators of cell death and survival pathways. Mice lacking cellular IAP (cIAP) 1 and either cIAP2 or X-linked IAP (XIAP) die in utero, and myeloid lineage-specific deletion of all IAPs causes sterile inflammation, but their role in the skin is unknown. We generated epidermal-specific IAPs deficient mice and found that combined genetic deletion of cIAP1 in keratinocytes and ubiquitous cIAP2 deletion (cIap1(EKO/EKO).cIap2(-/-)) caused profound skin inflammation and keratinocyte death, lethal by post-partum day 10...

Quality control is always the critical issue for Chinese medicines (CMs) with their worldwide increasing use. Different from western medicine, CMs are usually considered that multiple constituents are responsible for the therapeutic effects. Therefore, quality control of CMs is a challenge. In 2011, the strategies for quantification, related to the markers, reference compounds and approaches, in quality control of CMs were reviewed (Li, et al., J. Pharm. Biomed. Anal., 2011, 55, 802-809). Since then, some new strategies have been proposed in these fields...

REVIEW
David C Spray, Menachem Hanani
Enhanced expression and function of gap junctions and pannexin (Panx) channels has been associated with both peripheral and central mechanisms of pain sensitization. At the level of the sensory ganglia, evidence includes augmented gap junction and pannexin1 expression in glial cells and neurons in inflammatory and neuropathic pain models and increased synchrony and enhanced cross-excitation among sensory neurons by gap junction-mediated coupling. In spinal cord and in suprapinal areas, evidence is largely limited to increased expression of relevant proteins, although in several rodent pain models, hypersensitivity is reduced by treatment with gap junction/Panx1 channel blocking compounds...
