Citrate and Polyvinylpyrrolidone Stabilized Silver Nanoparticles as Selective Colorimetric Sensor for Aluminum (III) Ions in Real Water Samples [PDF]
, 2020 The use of silver nanoparticles stabilized with citrate and polyvinylpyrrolidone as a sensor for aluminum ions determination is proposed in this paper. These non-functionalized and specific nanoparticles provide a highly selective and sensitive detection

Loqs-PD and R2D2 define independent pathways for RISC generation in Drosophila [PDF]
Nucleic Acids Research, 2011 In Drosophila, siRNAs are classified as endo- or exo-siRNAs based on their origin. Both are processed from double-stranded RNA precursors by Dcr-2 and then loaded into the Argonaute protein Ago2. While exo-siRNAs serve to defend the cell against viruses, endo-siRNAs restrict the spread of selfish DNA in somatic cells, analogous to piRNAs in the germ ...

Structural mechanism of R2D2 and Loqs-PD synergistic modulation on DmDcr-2 oligomers
Nature Communications, 2023 AbstractSmall interference RNAs are the key components of RNA interference, a conserved RNA silencing or viral defense mechanism in many eukaryotes. In Drosophila melanogaster, Dicer-2 (DmDcr-2)-mediated RNAi pathway plays important roles in defending against viral infections and protecting genome integrity.

Structural Basis of MicroRNA Biogenesis by Dicer-1 and Its Partner Protein Loqs-PB
Molecular Cell, 2022 SUMMARYIn animals and plants, Dicer enzymes collaborate with double-stranded RNA-binding proteins to convert precursor-microRNAs (pre-miRNAs) into miRNA duplexes. We report six cryo-EM structures of Drosophila Dicer-1 and its partner Loqs-PB. The structures show Dicer-1•Loqs-PB (1) before binding pre-miRNA, (2) after binding and in a catalytically ...

Fluoroquinolone residues in raw cow's milk
Czech Journal of Food Sciences, 2011 The aim of the study was to monitore the levels of fluoroquinolone residues in bulk samples of raw cow's milk. The bulk samples of raw cow's milk (n = 150) were obtained from 58 different milk suppliers in the South Moravian and Vysočina Regions.
