Successful Percutaneous Revascularization for Femoral Artery Occlusion After Catheter Intervention: Serial Case Report

Femoral artery (FA) occlusion is a prevalent adverse event after catheter interventions, particularly in neonates and infants. Several treatments are available for FA occlusion, but the optimal approach remain...

Haploid plants carrying a sodium azide-induced mutation (fdr1) produce fertile pollen grains due to first division restitution (FDR) in maize (Zea mays L.)

We induced a fdr1 mutation in maize which makes haploid plants male fertile due to first division restitution; the optimum sodium azide treatment on maize ke...

Phenotypic and gene expression analyses of a ploidy series of maize inbred Oh43

Polyploidization has repeatedly occurred during plant evolution. Although autopolyploidy is the best model to characterize the polyploidization effects in a highly controlled manner, there are limited studies ...

Agrobacterium-mediated transformation of maize (Zea mays) with Cre-lox site specific recombination cassettes in BIBAC vectors

The Cre/loxP site-specific recombination system has been applied in various plant species including maize (Zea mays) for marker gene removal, gene targeting, and functional genomics. A BIBAC vector system was ada...

Distinct chromosomal distributions of highly repetitive sequences in maize

The majority of genomic DNA in most plant species is made up of repetitive elements including satellites and retrotransposons. The maize genome is intermediate in size and abundance of repetitive elements betw...

Genetic variation for the response to ploidy change in Zea mays L.

Polyploidization is an important process in the evolutionary history of most eukaryotic species. It oftentimes causes large-scale genomic reorganizations and is accompanied by a wide variety of phenotypic alte...

A test for ectopic exchange catalyzed by Cre recombinase in maize

A maize line expressing Cre recombinase as well as the recipient line without the transgene were assayed for evidence of ectopic recombination within the maize genome. Such a test is valuable for understanding...

Effects of stand density on the productivity ofCryptomeria japonica male flowers

We have studied male flower production and relative illumination in clonal sugi (Cryptomeria japonica) forests planted at densities of 1,500/ha, 3,000/ha, and 5,000/ha, to clarify the effects of forest management...

Induced single fertilization in maize

 Bicellular pollen with one vegetative nucleus and one diploid arrested generative cell (”monospermic” pollen) was induced by trifluralin treatment of diploid maize plants at 7–9 days before flowering. The arr...

Thermoelectric properties of oxide ceramics

Thermoelectric properties of several oxides were investigated. Al₂O₃-, TiO₂- or ZrO₂-doped ZnO showed large power factor over the wide temperature range. Fe₂O₃. showed large power factor by do** of TiO₂. BaO-do...

Selective Peak Enhancement and Suppression in Conductometric Ion Chromatography and Its Application to the Determination of Trace Levels of Orthophosphate in Environmental Samples

In non-suppressed conductometric ion chromatography, when a carboxylic acid eluent of low pH is used, the signal intensity (ΔH_C) is proportional to the sum of the conductivity change caused by changes in the samp...

Preparation of fine Ni particles by the spray-pyrolysis technique and their film forming properties in the thick film method

Fine Ni particles were directly prepared from Ni(NO₃)₂ and NiCl₂ aqueous solutions by the spray-pyrolysis technique under an H₂-N₂ atmosphere. Hollow Ni particles with rough surfaces were obtained at a low reacti...
