For over a decade our group has been designing, preparing and evaluating bioactive, remineralizing composites based on amorphous calcium phosphate (ACP) fillers embedded in polymerized methacrylate resin matrices. In these studies a major focus has been on exploring structure-property relationships of the matrix phase of these composites on their anti-cariogenic potential. The main challenges w...
Sphingosine 1-phosphate (S1P) is a lysophospholipid mediator which activates G protein-coupled sphingosine 1-phosphate receptors and thus evokes a variety of cell and tissue responses including lymphocyte trafficking, endothelial development, integrity, and maturation. We performed five all-atom 700 ns molecular dynamics simulations of the sphingosine 1-phosphate receptor 1 (S1P₁) based on rece...
Membrane-integrated type II phosphatidic acid phosphatases (PAP2s) are important for numerous bacterial to human biological processes, including glucose transport, lipid metabolism, and signaling. Escherichia coli phosphatidylglycerol-phosphate phosphatase B (ecPgpB) catalyzes removing the terminal phosphate group from a lipid carrier, undecaprenyl pyrophosphate, and is essential for transport ...
Narcolepsy with cataplexy is characterized by daytime sleepiness, cataplexy (sudden loss of bilateral muscle tone triggered by emotions), sleep paralysis, hypnagogic hallucinations and disturbed nocturnal sleep. Narcolepsy with cataplexy is most often associated with human leucocyte antigen-DQB1*0602 and is caused by the loss of hypocretin-producing neurons in the hypothalamus of likely autoimm...
Background: Fahr's syndrome (FS) is a movement and psychiatric disorder characterized by symmetrical bilateral calcification of the basal ganglia. Dissociative amnesia rare that occurs after stressful events classified as dissociative disorder. In addition, dissociation process which mind conceals from consciousness. Several neuropsychiatric manifestations in FS have been reported. However, due...
Background & Objective: The presence of nitrate and phosphate in concentrations above the allowable level in surface and groundwater resources leads to disease and problems. The aim of this study was to investigate the adsorption efficiency of magnetic-metallic chitosan nanocomposite in the adsorption of nitrate and phosphate from aqueous solutions. Materials and methods: The adsorbent was synt...
Stable derivatives of oxaphosphaphenanthrenes were prepared using multicomponent reactions of 3-bromo-2-naphthol, dialkyl acetylenedicarboxylate and trimethyl or triphenyl phosphite under microwave conditions with good yields.
ABSTRACT-The enrichment of bedding for vermicomposting systems with organic and inorganic additives is a technique which can promote the quality of produced vermicompost. Phosphate rock and fishmeal are two available and low-cost substances which can be provided easily and inoculation of vermicompost with phosphate solubilizing microorganisms (PSMs) can enhance the availability...
â â â â â abstract: â as the number of independent countries increases and their economies become more integrated, we would expect to observe more multi-country currency ::::union::::s. this paper explores the pros and cons for different countries to adopt as an anchor the us dollar, the euro or the yen. in addition, it addresses the question of how co-movement of outputs and prices would res...
Due to the excessive use of chemical fertilizers and also the lack of adequate information on the growth responses of ornamental plants to bio-fertilizers and municipal solid waste compost, this investigation was carried out on Zinnia. Therefore, a field experiment was conducted in complete randomized block design with three replications. Fertilizers included municipal solid waste compost, phos...
