Phosphoglycerate kinase catalyzes the phosphorylation of 3-phosphoglycerate to 1,3-diphosphoglycerate using ATP within the Calvin-Benson cycle. Recent proteomic analysis of thioredoxin targets in Synechocystis sp. PCC6803 revealed this enzyme as one of the target candidates, and we present here further characterization of the interaction between these(More)
It is possible that the flavonoids that are found in many foods might have a protective effect against osteoclastic activity. However, little information is available about the effects of flavonoids on osteoblastogenesis. Therefore, we investigated the effects of quercetin, a flavonoid, on the metabolism of rat calvarial osteoblast-like cells (ROB cells) in(More)
Alkylphenols are endocrine disruptors that show estrogen-like effects in various wildlife species. However, little information is available about the action of these chemicals on bone metabolism. We investigated the effects of alkylphenols, such as nonylphenol (NP) and octylphenol (OP), on the formation of bone using several culture systems for osteoclasts(More)
Tributyltin is ubiquitous in the environment and an endocrine disruptor for many wildlife species. However, minimal information is available regarding the effect of this chemical on bone formation. When tributyltin chloride (TBT) (1mg/kg body weight) was administered subcutaneously to pregnant mice at 10, 12, and 14 days post coitus (dpc), fetuses at 17.5(More)
To study increase of the Salmonella population in the cecum of chickens infected with Eimeria tenella, quantitative changes in mannose residues on the cecal mucosa were investigated. Inhibition of S typhimurium adherence to the cecum by a 2% carbohydrate (D-mannose, D-galactose, L-fucose, alpha-methyl-D-glucoside) in phosphate-buffered saline solution was(More)
Two modes of shedding of rod disc membranes were observed by electron microscopy in bullfrog retinas illuminated for various periods from 10 min to 2 hr. One mode is "autonomous shedding" whereby rods shed disc packets directly into the subretinal space. Most of the discarded disc packets are subsequently brought into contact with villous apical processes(More)
Holographic data storage is a promising technology that provides very large data storage capacity, and the multiplexing method plays a significant role in increasing this capacity. Various multiplexing methods have been previously researched. In the present study, we propose a shift-peristrophic multiplexing technique that uses spherical reference waves,(More)
