In this article, we assign the D∗ s3(2860) to be a D-wave cs̄ meson, study the vertices D∗ s3(2860)DK and D ∗ s3(2860)D ∗K in details to select the pertinent tensor structures, calculate the hadronic coupling constants GD∗ s3(2860)DK and GD∗ s3(2860)DK with the three-point QCD sum rules and obtain the decay widths Γ (D∗ s3(2860) → D ∗K) and Γ (D∗ s3(2860) → DK). The predicted ratio R = Γ (D∗ s3(...
BACKGROUND We examined kinetics and characterization of regenerating proximal tubule (PT) cells after various degrees of tubular injury in S3 segments of PT and assessed label-retaining slow cycling cells in S3. METHODS PT injury was induced by different doses of uranyl acetate (UA) injection into rats, and initially regenerating PTs were identified by in vivo bromodeoxyuridine (BrdU)-labelli...
Introduction: Antimicrobial peptides (AMPs) are compounds with antimicrobial properties that are studied widely due to the development of resistance of pathogenic bacteria to antibiotics. In the present study, the toxicity and antimicrobial effects of two natural monomeric peptides (S3 and S∆3) were compared with S3-S∆3 hybrids and S3 tetramers. Material & Methods: Protein hybrids (S∆3S3-2mer-G...
Membrane-embedded voltage-sensor domains in voltage-dependent potassium channels (K(v) channels) contain an impressive number of charged residues. How can such highly charged protein domains be efficiently inserted into biological membranes? In the plant K(v) channel KAT1, the S2, S3, and S4 transmembrane helices insert cooperatively, because the S3, S4, and S3-S4 segments do not have any membr...
