Two procedures are described for the fractionation of chromatin containing unsubstituted (LL) DNA and DNA unifilarly substituted with bromodeoxyuridine (HL). The two procedures rely upon the sensitivity of bromodeoxyuridine-containing DNA to UV light to induce either strand breakage or protein crosslinking. When a mixture of LL and HL chromatin is irradiated with UV light, the HL DNA fragments ...

The present research tests Japanese listeners’ perception of Italian liquids under the framework of the Perceptual Assimilation Model (PAM), a model of non-native speech perception. The study examines the discrimination and the identification of Italian liquids (/l/, /r/, /ll/, /rr/ and /ʎ/), while comparing the results with those of replicated perception experiments of Spanish liquids (/l/, /ɾ...

The human cathelicidin hCAP18/LL-37 is an antimicrobial protein consisting of a conserved N-terminal prosequence called the cathelin-like domain and a C-terminal peptide called LL-37. This peptide contains 37 amino acid residues, and several truncated variants obtained from natural sources or by chemical synthesis differ in their capability to damage Gram positive and Gram negative bacteria as ...

The purpose of our study is to evaluate sagittal parameters in 2-level lumbar degenerative spondylolisthesis (DS) (TLDS).A total of 15 patients with TLDS, 40 patients with single-level DS (SLDS), and 30 normal volunteers as control were included in our study. All subjects performed on full spine X-ray. Two categorized data were analyzed: patient characteristics-age, sex, body mass index, radiog...

BACKGROUND Identifying physiologically relevant binding partners of amyloid-β (Aβ) that modulate in vivo fibril formation may yield new insights into Alzheimer's disease (AD) etiology. Human cathelicidin peptide, LL-37, is an innate immune effector and modulator, ubiquitous in human tissues and expressed in myriad cell types. OBJECTIVE We present in vitro experimental evidence and discuss fin...

Tannerella forsythia is a gram-negative bacterium strongly associated with the development and/or progression of periodontal disease. Here, we have shown that a newly characterized matrix metalloprotease-like enzyme, referred to as karilysin, efficiently cleaved the antimicrobial peptide LL-37, significantly reducing its bactericidal activity. This may contribute to the resistance of T. forsyth...
