Lei Zhang, Satoshi Okabe
Despite that anaerobic ammonium oxidizing (anammox) bacteria are key players in the global nitrogen cycle, no pure cultures are still available. Planktonic cell culture with high purity is, therefore, essential for physiological and biochemical studies of anammox bacteria. However, development of such planktonic cell cultures requires an enormous amount of time and effort. Here we developed a novel rapid method for cultivating free-living planktonic anammox cells. First, anammox granules were physically dispersed, immobilized in 6% polyvinyl alcohol-4% sodium alginate (PVA-SA) gel beads, and then pre-cultured in an up-flow column reactor...

Zinc is an essential component of the insulin granule and it possibly modulates insulin secretion and signaling. Since insulin resistance is a hallmark in the development of type 2 diabetes mellitus, this study aimed at investigating if zinc supplementation is able to improve glucose tolerance and β-cell function in a model of insulin resistance. Male C57BL/6 mice were distributed in four groups according to the diet: normal fat (NF); normal fat supplemented with ZnCl₂ (NFZ); high-fat (HF); and, high-fat chow supplemented with ZnCl₂ (HFZ)...

BACKGROUND: Within the endoplasmic reticulum, thiol isomerase enzymes modulate the formation and rearrangement of disulphide bonds in newly folded proteins entering the secretory pathway to ensure correct protein folding. In addition to their intracellular importance, thiol isomerases have been recently identified to be present on the surface of a number of cell types where they are important for cell function. Several thiol isomerases are known to be present on the resting platelet surface including PDI, ERp5 and ERp57 and levels are increased following platelet activation...

Growing recognition of persistent cognitive defects associated with electroconvulsive therapy (ECT), a highly effective and commonly used antidepressant treatment, has spurred interest in identifying its mechanism of action to guide development of safer treatment options. However, as repeated seizure activity elicits a bewildering array of electrophysiological and biochemical effects, this goal has remained elusive. We have examined whether deletion of Narp, an immediate early gene induced by electroconvulsive seizures (ECS), blocks its antidepressant efficacy...

REVIEW
Xiao-Ye Wang, Rui-Chao Lin, Shi-Fen Dong, Jun Guan, Lu Sun, Jian-Mei Huang
Mineral Chinese medicine is the distinctive part of the Chinese traditional medicine. The mineral Chinese medicines containing mercury elements such as cinnabaris, calomelas and hydrargyri oxydum rubrum are widely applied in the clinical conditions because of their efficacy of sedative, sterilization, removing necrotic tissue and promoting granulation. However, the rationality and security of clinical application are questioned because of the toxic effect caused by mercury compounds. This paper would summarize the efficacy of the mineral Chinese medicines containing mercury element, as well as their hepatotoxicity, nephrotoxicity, embryotoxicity, and neurotoxicity effect and mechanisms...

Oocyte vitrification causes less cell stress than slow cooling, but cytoskeletal and spindle alterations may occur affecting the oocyte competence. In vitro maturation (IVM) supplementation with different antioxidant molecules has been performed to attenuate this harmful stress. Coenzyme Q10 (CoQ10 ) supplementation has previously shown to have positive effects in bovine and mouse in vitro embryo development. The aim of this study was to evaluate the effects of CoQ10 during bovine oocyte IVM and vitrification...

We sequenced the metagenome of a granular sludge in a nitritation/anammox bioreactor used for the treatment of ammonium-rich wastewater. Proteobacteria, Planctomycetes, Bacteroidetes, Chloroflexi, Ignavibacteriae, and Acidobacteria were the predominant phyla in the studied bioreactor. Binning of contigs yielded a near-complete genome of the dominant anammox bacterium assigned to the candidate genus Brocadia.

Sphenostylis stenocarpa (Hochst. ex A. Rich.) Harms, is a legume widely recognized in Africa for its edible starchy tuber and seeds. In the present morphological, structural and functional properties of starch extracted from the tubers and seeds of a same accession of this plant were characterized and compared. With smaller and more angular granules, tuber starch displayed higher resistance toward amylolysis and gelatinization than seed starch. The amylolysis of seed starch resulted in fragmented granules with typical layered structures of growth rings...

Sympathetic ophthalmia (SO) is a rare, bilateral, non-necrotizing, granulomatous uveitis that usually occurs after open ocular injury or intraocular surgery. The pathophysiology is not clearly understood, but generally SO is an immediate hypersensitivity mediated by T lymphocytes which are related to ocular tissue antigens. The main histopathological features are granulation tissues composed of lymphocytes, macrophages and multinucleated giant cells. The clinical manifestations are different from person to person, which might be mild or severe...

Bo Young Choi, Dae Ki Hong, Sang Won Suh
Our previous study demonstrated that colchicine-induced dentate granule cell death is caused by blocking axonal flow and the accumulation of intracellular zinc. Zinc is concentrated in the synaptic vesicles via zinc transporter 3 (ZnT3), which facilitates zinc transport from the cytosol into the synaptic vesicles. The aim of the present study was to identify the role of ZnT3 gene deletion on colchicine-induced dentate granule cell death. The present study used young (3-5 months) mice of the wild-type (WT) or the ZnT3(-)(/)(-) genotype...

BACKGROUND: Benign central airway tumors are very rare diseases. Their unspecific symptoms are responsible for late diagnosis. Endoscopic interventions with different techniques and tools are widely used for their treatment. However, in certain cases interventional endoscopy might be unsuccessful and therefore other methods such as high-dose-rate brachytherapy could be a therapeutic option. CASE PRESENTATION: A 76-year-old white German woman was referred to our clinic for an endoscopic treatment of a recurrent granulation polyp in her left main bronchus...

Fungicidal activity of experimental tebuconazole (TEB) formulations was investigated in laboratory soil ecosystems in wheat plant communities infected by Fusarium moniliforme. TEB was embedded in the matrix of poly-3-hydroxybutyrate, shaped as films and microgranules. These formulations were buried in the soil with wheat plants, and their efficacy was compared with that of commercial formulation Raxil and with the effect of pre-sowing treatment of seeds. In the experiment with the initially infected seeds and a relatively low level of natural soil infection caused by Fusarium fungi, the effects of the experimental P(3HB)/TEB formulations and Raxil were comparable...
