Efficient generation of tunable femtosecond pulses in the blue is reported in the nonlinear crystal BiB3O6. By use of fundamental pulses from a mode-locked Ti:sapphire laser at 76 MHz, single-pass second-harmonic average powers of as much as 830 mW have been generated at 50% conversion efficiency, and a tunable range of 375-435 nm in the blue is demonstrated. Temporal measurements using cross c...

It was found that a slide centrifuge (Cytospin) preparation of a cell suspension allowed a reliable assessment of not only cell structure but also the percentage of non-viable cells. The non-viable cells appeared as "smear" cells and paralleled in number the cells taking up trypan blue. Direct experiment showed the unstained viable cells in a trypan blue cell suspension remained intact in a Cyt...

Inrat liver microsomal fractions oxidation of adrenaline was effected by superoxide anion radicals (A), whereas cytochrome c, 2,6-dichlorophenol-indophenol and ferricyanide accepted electrons from NADPH-specific filavoprotein only directly. Nitro Blue Tetrazolium was reduced both by 02and by tbe direct acceptance of electrons. Elevation ofpH and addition of menadione shift the Nitro Blue Tetraz...

PURPOSE A new humanized anti-CD20 monoclonal antibody (MAb), IMMU-106, was evaluated to elucidate its action as an antilymphoma therapeutic, as a single agent, and in combination with the anti-CD22 MAb, epratuzumab. EXPERIMENTAL DESIGN Antiproliferative effects, apoptotic effects, and the ability of IMMU-106 to mediate complement-mediated cytotoxicity and antibody-dependent cellular cytotoxic...

Casein kinase1 (CK1) plays crucial roles in regulating growth and development via phosphorylating various substrates throughout the eukaryote kingdom. Blue light is crucial for normal growth of both plants and animals, and blue light receptor cryptochrome2 (CRY2) undergoes blue light–dependent phosphorylation and degradation in planta. To study the function of plant CK1s, systematic genetic ana...
