Reactive oxygen species (ROS) and reactive nitrogen species (RNS) are key regulators of redox homeostasis in living organisms including plants. As control of redox homeostasis plays a central function in plant biology, redox proteomics could help characterizing the potential roles played by ROS/RNS-induced post-translational modification (PTMs) in plant cells. In ...

Isotopic (10)BN sheets were first prepared using graphene sheets as templates to react with (10)B(2)O(3). The edge-areas of BN sheets have much higher oxygen-doping ratios compared to other areas. The emission peak of X-ray excited optical luminescence spectra of the (10)BN-sheets is broader and red-shifted because of the isotopic effect. ...

Diet-induced obesity produces changes in endocannabinoid signaling (ECS), influencing the regulation of energy homeostasis. Recently, we demonstrated that, in high-fat-diet-fed rats, blockade of CB1 receptor by AM251 not only reduced body weight but also increased adult neurogenesis in the hippocampus, suggesting an influence of diet on hippocampal cannabinoid function. To ...

Absorbance spectroscopy is used extensively to tell when two DNA single strands come together and form a double strand. Here we show that circular dichroism in the vacuum ultraviolet region provides an even stronger indication for duplex formation in the case of short strands of adenine and thymine (4 to ...

Synapses are highly dynamic structures that mediate cell-cell communication in the central nervous system. Their molecular composition is altered in an activity-dependent fashion, which modulates the efficacy of subsequent synaptic transmission events. Whereas activity-dependent trafficking of individual key synaptic proteins into and out of the synapse has been characterized previously, ...

The rotavirus spike protein domain VP8* is essential for recognition of cell surface carbohydrate receptors, notably those incorporating N-acylneuraminic acids (members of the sialic acid family). N-Acetylneuraminic acids occur naturally in both animals and humans, whereas N-glycolylneuraminic acids are acquired only through dietary uptake in normal human tissues. The preference ...

The role of reactive oxygen species (ROS) in glucose-stimulated insulin release remains controversial because ROS have been shown to both amplify and impede insulin release. In regard to preventing insulin release, ROS activates uncoupling protein-2 (UCP2), a mitochondrial inner membrane protein that negatively regulates glucose-stimulated insulin secretion (GSIS) by uncoupling ...

Luminol, Bluestar(®) , and Hemascein(®) were tested to compare detection sensitivities to latent blood. Untreated, EDTA-treated human blood, and a catalytically similar blood substitute were diluted (neat to 1:1,000,000) and pipetted onto a variety of substrates. Luminol and Bluestar(®) performed similarly on all surfaces and fabrics. Hemascein(®) yielded poor results ...
