BACKGROUND AND OBJECTIVE Th17 cells are important T helper cells, which are characterized by their production of IL-17. Th17 cells play an important role in host defense against microbial infections, autoimmune diseases and cancer. The aim of this study is to investigate the percentage of Th17 in peripheral blood lymphocyte and the level of IL-17 in serum(More)
Four meso-tetraphenylporphyrin derivatives bearing either triphenylphosphonium ion-(P1 and P2) or triethylammonium ion-(P3 and P4) terminated alkoxy group at either para-(P1 and P3) or meta-(P2 and P4) position of one meso-phenyl group were designed and synthesized. P1-P4 show similar absorption and fluorescence emission spectra and (1)O(2) quantum yields.(More)
[Ru(II)(bpy)(2)(dppn)](2+) (bpy = 2,2'-bipyridine, dppn = 4,5,9,16-tetraazadibenzo[a,c]naphthacene) was found to be able to photoinactivate Gram-negative Escherichia coli efficiently, showing the potential of transition-metal complexes as photosensitizers in the field of photodynamic antimicrobial chemotherapy (PACT).
Identification of epitopes which invokes strong humoral responses is an essential issue in the field of immunology. Various computational methods that have been developed based on the antigen structures and the mimotopes these years narrow the search for experimental validation. These methods can be divided into two categories: antigen structure-based(More)
Hypocrellin A (HA), an efficient phototherapeutic agent, can chelate with lanthanum ion to form a 1:1 complex, which exhibits enhanced 1O2 generation quantum yield, a red-shifted absorption window, greatly improved water solubility, a much lengthened triplet excited state lifetime, and an increased affinity to DNA with respect to HA. These effects in turn(More)
Fifteen complexes of hypocrellin A (HA) with rare earth trivalent ions (except Pm3+) along with the complex of HA with Sc3+ were prepared, and their photodynamic activities, including absorption in the phototherapeutic window (600-900 nm); water-solubility; triplet lifetime; generation of reactive oxygen species (ROS), such as singlet oxygen (1O2),(More)
To track nuclear dynamic processes by fluorescence imaging, nuclear stains should be highly fluorescent, resistant to photobleaching, and inert to nuclear processes. The nuclear stains of the Hoechst family, such as Hoechst 34580, show bright fluorescence only on groove binding to DNA, and therefore may interfere with visualization of nuclear dynamic(More)
[Cu(TMPA)Cl]Cl (1) and [Cu(Cl-TMPA)Cl2] (2) exhibited efficient photocatalytic H2 evolution with a TON of 6108 and 10014 (6 h), respectively, in CH3CN/H2O solution (9 : 1, v/v) containing an Ir complex as the photosensitizer and triethylamine as the sacrificial reductant, representing the first example of photocatalytic Cu complex-based water reduction(More)
Two new NIR-absorbing BODIPY dyes, each bearing two pyridinium groups, are synthesized and their DNA-binding affinities and DNA photocleavage abilities examined in depth. While one BODIPY dye photocleaves DNA mainly through singlet oxygen, the other photocleaves DNA through both singlet oxygen and hydroxyl radical. To the best of our knowledge, this is the(More)
