Genome-wide characterization of i-motifs and their potential roles in the stability and evolution of transposable elements in rice

I-motifs (iMs) are non-canonical DNA secondary structures that fold from cytosine (C)-rich genomic DNA regions termed putative i-motif forming sequences (PiMFSs). The structure of iMs is stabilized by hemiprotonated C-C base pairs, and their functions are now suspected in key cellular processes in human cells such as genome stability and regulation of gene transcription. In … Read more

Recombinant Bovine Enterokinase (rb-EK)

Enterokinase (EC 3.4.21.9) is a serine proteolytic enzyme, which can recognize the sequence of ASP ASP Lys (DDK) in the protein efficiently and specifically, hydrolyze the peptide bond at the C-terminal of lysine (Lys, K), produce cleavage, hydrolyze trypsinogen to trypsin in the organism. Because enterokinase has high specificity and efficient enzymatic cleavage, it is … Read more

Checklist and provisional atlas of singing cicadas (Hemiptera: Cicadidae) of Bulgaria, based on bioacoustics

Background: The Cicadas Singers (hemiptera: cigadidae) of Bulgaria were poorly known. There are records published for 14 species: Cicada Orni, Lyrists Plebejus, Cicadatra Atra, Cicadatra Hyalina, Cicadatra Persica, Cicadatta Persica, Cicadetta Montana, Cicadetta Mediterranea, Timissaleta Dimissa, Oliglena Tibialis, Tympanistalis Gastrica, Pagiphora Annulata, Saiticula Coriaria, Tibicina Haematodes and Tibicina Steveni. New information: Two species of this … Read more

A feasibility study on the association between residential greenness and neurocognitive function in middle-aged Bulgarians

A feasibility study on the association between residential greenness and neurocognitive function in middle-aged Bulgarians

Recent research indicated that exposure to residential vegetation (“greenery”) may be protective against cognitive decline and can support the integrity of the corresponding brain structures. However, it is still unclear about these effects, especially in less rich and middle-aged countries. In this study, we investigated the associations between greenery and neurocognitive function. We used a … Read more
