The sporogenesis and development of gametophytes in Tetracentron sinense Oliv. were studied with light microscopy. The anther has four microsporangia; its primary anther wall consists of an epidermis, an endothecium, one or two middle layers and one glandular tapetum. Simultaneous cytokinesis follows meiosis, forming a tetrahedral tetrad. Mature pollen grains are two-celled at the time of anthe...

The light-driven proton pump bacteriorhodopsin (BR) from Halobacterium salinarum is tightly regulated by the [H(+)] gradient and transmembrane potential. BR exhibits optoelectric properties, since spectral changes during the photocycle are kinetically controlled by voltage, which predestines BR for optical storage or processing devices. BR mutants with prolonged lifetime of the blue-shifted M i...

OBJECTIVES To examine the relation between rheumatoid arthritis (RA) and bronchiectasis (BR). METHODS Disease activity, outcome, extra-articular manifestations, and laboratory features were compared in 32 patients with BR and RA (RA-BR group), 32 matched patients with RA without BR (RA group), and 31 patients with BR but without arthritis (BR group). RESULTS In 30 of the 32 (94%) patients w...

Application of SEREX (serological analysis of recombinant tumor cDNA expression libraries) to different tumor types has led to the identification of several categories of human tumor antigens. In this study, the analysis of a breast cancer library with autologous patient serum led to the isolation of seven genes, designated NY-BR-1 through NY-BR-7. NY-BR-1, representing 6 of 14 clones isolated,...

BACKGROUND Treatment of multidrug-resistant tuberculosis (MDR-TB) is complex, lengthy, and involves a minimum of four drugs termed a background regimen (BR), that have not previously been prescribed or that have proven susceptible to patient sputum culture isolates. In recent years, promising new treatment options have emerged as add-on therapies to a BR. The aim of this study was to evaluate t...

The evolution of complete metamorphosis in insects is a key innovation that has led to the successful diversification of holometabolous insects, yet the origin of the pupa remains an enigma. Here, we analyzed the expression of the pupal specifier gene broad (br), and the effect on br of isoform-specific, double-stranded RNA-mediated silencing, in a basal holometabolous insect, the beetle Tribol...

In a previous study, we found that 2-deoxyribonolactone is effectively generated in the specific 5-bromouracil ((Br)U)-substituted sequence 5'-(G/C)[A]n = 1,2 (Br)U(Br)U-3' and proposed that a formed uracil-5-yl radical mainly abstracts the C1' hydrogen from the 5'-side of (Br)U(Br)U under 302-nm irradiation condition. In the present work, we performed photoirradiation of (Br)U-substituted DNA ...
