Granulated blast furnace slag (GGBFS) is a potential resource of rare earth elements (REEs), and due to the complex mineralogy, extraction by conventional hydrometallurgical process makes it an acid-consuming method. Bioleaching thus investigated using chemo-organotrophic bacterium Gluconobacter oxydans (DSMZ 46616) for REE from GGBFS containing 157 ppm Ce, 90 La, 71 Nd 40 Er, hosted in Ca-Al-S...

The present study investigated the protective effects and molecular mechanism of prostaglandin A1 (PGA1) and triptolide (TRI) on apoptosis of cardiac microvascular endothelial cells (CMVECs) in rats. CMVECs of rats were isolated and then cultured. MTT method was used to select and establish a cell hypoxia reoxygenation cell model. The cells were divided into four groups: Normoxia control group ...

Several algorithms of maximum search are investigated and evaluated in different types of P systems, namely using priorities, multiple nested membranes and linked transport. The proposed solutions are expected to find application in a wide range of problems. In particular, the authors are currently working on modeling an algorithm for DNA sequence alignment using P systems.

  Introduction: Radioimmunotherapy (RIT) is a very promising new therapy for the treatment of recurrent B-Cell non-Hodgkin's lymphoma (NHL). Iodine-131 is the most frequently used nuclide in clinical RIT, but its usefulness has been limited by dehalogenation of monoclonal antibodies labeled via conventional methods. To circumvent this problem, we have synthesized a tr...

Phosphorus (P) availability in calcareous forest soils is commonly low compared to siliceous soils. The main reason for this that phosphate ions tend precipitate with calcium (Ca). Weathering of rocks and the potential microorganisms dissolve parent material not fully understood. Therefore, we examined microbial carbonate dissolution abundance phosphorus-solubilizing bacteria temperate contrast...

The present study aimed to investigate the involvement of the Suv39H1 histone methyltransferase in the epigenetic changes in the euchromatic promoter in gastric carcinoma. We retrospectively analyzed the protein of Suv39H1 and tri-methylated histone H3 lysine 9 (H3K9) and histone H3 lysine 4 (H3K4) in 175 cases of gastric carcinoma by immunohistochemistry. Suv39H1 was depleted by siRNA, and cel...

Phosphorus (P) is one of the most important elements required for crop production. The ideal soil pH its absorption by plants about 6.5, but in alkaline and acidic soils, consumed P forms an insoluble complex with calcium, iron, aluminum availability plant decreases. supply needed mainly achieved through chemical fertilizers; however, addition to high price these fertilizers, long run, their de...

The ability to solubilize insoluble inorganic phosphate compounds by Gluconacetobacter diazotrophicus was studied using different culture approaches. Qualitative plate assays using tricalcium phosphate as the sole P-source showed that G. diazotrophicus produced solubilization only when aldoses were used as the C-source. Extracellular aldose oxidation via a pyrroloquinoline quinone-linked glucos...
