Measurement of the UV-visible absorption spectrum is a convenient technique for detecting chemical changes of proteins, and it is therefore useful to combine spectroscopy and diffraction studies. An online microspectrophotometer for the UV-visible region was developed and installed on the macromolecular crystallography beamline, BL38B1, at SPring-8. This spectrophotometer is equipped with a dif...

Cutaneous immunity, which is a key defence against the development of skin cancers, is suppressed by even small doses of ultraviolet (UV) radiation. Preventing this UV-induced immunosuppression may therefore reduce the incidence of skin cancer. Nicotinamide (vitamin B3) has immune-protective and cancer-preventive effects against UV radiation in mice, and we have shown previously that topical ni...

The removal efficiency of 4-chlorophenol with different advanced oxidation processes have been studied. Oxidation experiments were carried out using two 4-chlorophenol concentrations: 100 mg L and 250 mg L and UV generated from a KrCl excilamp with (molar ratio H2O2: 4-chlorophenol = 25:1) and without H2O2, and, with Fenton process (molar ratio H2O2:4chlorophenol of 25:1 and Fe concentration of...

We show the efficacy of a therapeutic strategy that combines the potency of a DNA-binding photosensitizer, UV(A)Sens, with the tumor-targeting potential of receptor-mediated endocytosis. The photosensitizer is an iodinated bibenzimidazole, which, when bound in the minor groove of DNA and excited by UV(A) irradiation, induces cytotoxic lesions attributed to a radical species resulting from photo...

Abstract Responses of rice seedlings to UV‐B radiation (UV‐B) were investigated, aiming establish as a model plant for signalling studies. The growth japonica coleoptiles, grown under red light, was inhibited by brief irradiation with UV‐B, but not blue light. effective fluences (10 −1 ‐10 3 μmol m −2 ) much lower than those reported in Arabidopsis. response less indica cultivars and its extent...

Abstract We present the first catalog of supernova remnants (SNRs) in M31 that exhibit diffuse ultraviolet (UV) emission. UV images were obtained by Ultraviolet Imaging Telescope (UVIT) on AstroSat satellite, and list SNRs was from X-ray, optical, radio catalogs M31. used UVIT to find with emission, omitting those too contaminated stellar A total 20 detected Fluxes F148W, F169M, F172M, N219M, N...

A pea (Pisum sativum) DNA fragment (termed MB3) was isolated by differential display of cDNAs obtained from total leaf RNA of ultraviolet B (UV-B) radiation-treated plants. Longer cDNAs were cloned by rapid amplification of cDNA ends in the 3' to 5' direction. Three different, but very similar, cDNAs were cloned, sadA, sadB, and sadC, the major difference between them being a 36-bp deletion in ...

To investigate the clinical applicability of prophylaxis of post-transplant graft-versus-host disease by UV-B irradiation of stem cell preparations, the UV-B sensitivities of human lymphocytes and primitive hematopoietic progenitors were compared. The mononuclear cell fractions (MNC) derived from human cord blood and granulocyte–colony-stimulating factor–mobilized peripheral blood were used. Af...

Antibiotic A3 5512B1.2) is a member of the glycopeptide family of antibiotics; complete structures have been reported for two members of this group, vancomycin3' and ristocetin A4' a) . Both vancomycin and ristocetin have been shown to form complexes with mucopeptides containing the terminal dipeptide D-alanyl-D-alaninee) ; this interaction within the bacterial cell inhibits crosslinking of the...

If G is a graph, and if for e = uv ? E(G) the number of vertices closer to u than v denoted by nu, then Mo(G) uv?E(G) |nu-nv| Mostar index G. In this paper, studied on trees graph products.
