With the advent of next-generation sequencing technology, there is rapidly increasing interest in long noncoding RNAs (lncRNAs). The objectives of this study were to develop a novel lncRNA MALAT1 near-infrared optical probe, to evaluate the characteristics of this optical imaging probe in vitro and to determine whether it can be used for imaging MALAT1 expression in malignant tumours in vivo. Conjugation of Cy5.5 to MALAT1 ASO was accomplished using standard NHS (N-hydroxysuccinimide) ester procedures, and the labelled MALAT1 ASO was purified with a Glen-Pak DNA Purification Cartridge and reversed-phase high performance liquid chromatography (HPLC)...

Presence of the antidepressant fluoxetine in different water bodies has raised significant concerns due to its detrimental effects on non-targeted organisms, especially on fish. When seeking for an appropriate technology able to remove fluoxetine residue from a complex water matrix, special attention needs to be paid to the elimination of the neurophysiological activity that eventually lies behind the noxious effects of the parent compound. Our aim was to probe the applicability of advanced oxidation techniques for this purpose using in situ generated free radical system based on OH-initiated peroxyl radical-mediated processes...

Advances in next-generation sequencing technologies contribute to the identification of (candidate) disease genes for movement disorders and other neurological diseases at an increasing speed. However, little is known about the molecular mechanisms that underlie these disorders. The genetic, molecular, and behavioral toolbox of Drosophila melanogaster makes this model organism particularly useful to characterize new disease genes and mechanisms in a high-throughput manner. Nevertheless, high-throughput screens require efficient and reliable assays that, ideally, are cost-effective and allow for the automatized quantification of traits relevant to these disorders...

Arabidopsis thaliana (Arabidopsis) seedlings often need to be grown on sterile media. This requires prior seed sterilization to prevent the growth of microbial contaminants present on the seed surface. Currently, Arabidopsis seeds are sterilized using two distinct sterilization techniques in conditions that differ slightly between labs and have not been standardized, often resulting in only partially effective sterilization or in excessive seed mortality. Most of these methods are also not easily scalable to a large number of seed lines of diverse genotypes...
