In the present study, we investigated the peroxidase-catalyzed detoxification of model phenolic compounds and evaluated the inhibitory effects of the detoxified solution on butanol production by Clostridium beijerinckii National Collection of Industrial and Marine Bacteria Ltd. 8052. The six phenolic compounds, p-coumaric acid, ferulic acid,(More)
A grass rhizosphere bacterium, Enterobacter intermedium (60-2G), has a strong ability to solubilize insoluble phosphate. Certain phosphate-solubilizing bacteria secrete gluconic acid for this process. The gluconic acid is produced by direct extracellular oxidation of glucose by a glucose dehydrogenase equipped with pyrroloquinoline quinone (PQQ) as a(More)
BACKGROUND Glyphosate-surfactant herbicide is promoted by the manufacturer as having no risks to human health. Glyphosate surfactant has recently been used with increasing frequency in suicide attempts, so clinical toxicologists occasionally encounter cases of severe systemic toxicity. The purpose of this study was to identify the early predictive factors(More)
The chemical and gel characteristics of carrageenans isolated from the most abundant algal species growing on the Russian Pacific coast – Chondrus pinnulatus, C. armatus and Iridaea cornucopiae belonging to the Gigartinaceae and Tichocarpus crinitus from the Tichocarpaceae were investigated. The polysaccharides were identified by FTIR and NMR spectroscopy(More)
Lipase B from Candida antarctica (CalB) is a versatile biocatalyst for various bioconversions. In this study, the thermostability of CalB was improved through the introduction of a new disulfide bridge. Analysis of the B-factors of residue pairs in CalB wild type (CalB-WT) followed by simple flexibility analysis of residues in CalB-WT and its designated(More)
Purpose. To investigate the specific role of Pinin (Pnn) in the development of anterior eye segment in mice. Methods. Conditional inactivation of Pnn in the developing surface eye ectoderm and lens was achieved by creating mice carrying a Pnn null and a floxed Pnn allele as well as a Pax6-Cre-GFP (Le-Cre) transgene. The resultant Pnn conditional knockout(More)
We report the real-time detection of protein using SWNT-FET-based biosensors comprising DNA aptamers as molecular recognition elements. Anti-thrombin aptamers that are highly specific to serine protein thrombin were immobilized on the sidewall of a SWNT-FET using CDI-Tween linking molecules. The binding of thrombin aptamers to SWNT-FETs causes a rightward(More)
Recent advances in nanotechnology have enabled the development of nanoscale sensors that outperform conventional biosensors. This review summarizes the nanoscale biosensors that use aptamers as molecular recognition elements. The advantages of aptamers over antibodies as sensors are highlighted. These advantages are especially apparent with electrical(More)
Calcineurin B-like protein-interacting protein kinases (CIPKs) are a group of typical Ser/Thr protein kinases that mediate calcium signals. Extensive studies using Arabidopsis plants have demonstrated that many calcium signatures that activate CIPKs originate from abiotic stresses. However, there are few reports on the functional demonstration of CIPKs in(More)
Spontaneous bilateral rupture of the quadriceps tendons without a significant history of trauma is an uncommon disease. It is generally associated with chronic metabolic disorders such as chronic renal failure and secondary hyperparathyroidism. Here, we report a case of spontaneous bilateral tendon rupture in a patient on chronic hemodialysis for the past 5(More)
