Stacking registry determination of graphene grown on the SiC(0001) by photoelectron holography

Hirosuke Matsui, Fumihiko Matsui, Naoyuki Maejima, Tomohiro Matsushita, Hiroshi Daimon
2015 Surface Science  
The subsurface structures on top of a 4H-SiC(0001) at two defined thermal graphitization stages, the graphene precursor terminated with (6√3 × 6√3)-R30°periodicity and single-layer graphene (SLG), were characterized by photoelectron holography. The local atomic configuration at the graphene precursor layer and single-layer graphene (SLG) as well as the interface buffer layer were reconstructed. The existence and similarity of local buckling were confirmed on both the precursor and buffer

1997 Biochemical Journal  
In order to investigate the role of osteocytes in bone resorption, we examined the homogenate and conditioned medium from purified chick calvarial osteocytes in a pit-formation assay using unfractionated bone cells from mice. The osteocyte homogenate markedly inhibited pit formation, whereas the conditioned medium of osteocytes had no effect. This inhibitory activity was not the result of cytotoxicity of the homogenate. A novel boneresorption-inhibitory protein was purified from

Magnaporthe oryzae endopolygalacturonase homolog correlates with density-dependent conidial germination

Takuma Mori, Hee-Young Jung, Kensaku Maejima, Hisae Hirata, Misako Himeno, Hiroshi Hamamoto, Shigetou Namba
2008 FEMS Microbiology Letters  
Endopolygalacturonases (endoPGs) of some phytopathogens are virulent factors for dicots. To investigate the function of the endoPG of Magnaporthe oryzae, a disruption mutant of MGG_08938, the homolog of endoPG found in the genome database of this fungus, was generated. The pathogenicity, mycelial growth, and appressorium formation of this mutant were comparable with those of the wild-type strain; however, the germination of conidia in a highly concentrated suspension of conidia was affected by

The authors named the gene MDG1 (M. oryzae density-dependent germination), which delineates this new function in the fungus.

Trends in Paraquat Poisoning in Japan - Viewed from Surveys on Clinical Cases

Hiroshi Nagami, Fumio Maejima, Yoshio Nishigaki, Shusuke Natsukawa
2013 Journal of Rural Medicine  
Paraquat poisoning occurs worldwide, and both the fatality rate and the number of deaths are out of the ordinary. Japan is one of the few countries in the world that have replaced 24% products with 5% products. This report is an attempt to introduce information about paraquat poisoning in Japan. The Japanese Association of Rural Medicine has carried out extensive surveys on clinical cases of pesticide poisoning at its 122 member installations since 2007. Of all the findings, we have picked out

The rate of deaths from suicide attempts with paraquat stands at somewhere near 80% or so even with 5% products, so it appears that the attempts to reduce the death rate did not have the intended effect even with products having a lower concentration. The "outcome prediction line" propounded in 1979 still stands today, while a wide variety of therapies have been studied. It seems that paraquat should at least be classified into Class Ib (highly hazardous) given that the mortality remains high and efficacious therapies remain elusive.

2017 Gait & Posture  
Augmented sensory biofeedback (BF) for postural control is widely used to improve postural stability. However, the effective sensory information in BF systems of motor learning for postural control is still unknown. The purpose of this study was to investigate the learning effects of visual versus auditory BF training in dynamic postural control. Eighteen healthy young adults were randomly divided into two groups (visual BF and auditory BF). In test sessions, participants were asked to bring

The target moved in seven cycles of sine curves at 0.23 Hz in the vertical direction on a monitor. In training sessions, the visual and auditory BF groups were required to change the magnitude of a visual circle and a sound, respectively, according to the distance between the COP and target in order to reach the target. The perceptual magnitudes of visual and auditory BF were equalized according to Stevens' power law. At the retention test, the auditory but not visual BF group demonstrated decreased postural performance errors in both the spatial and temporal parameters under the no-feedback condition. These findings suggest that visual BF increases the dependence on visual information to control postural performance, while auditory BF may enhance the integration of the proprioceptive sensory system, which contributes to motor learning without BF. These results suggest that auditory BF training improves motor learning of dynamic postural control.

2015 Physical Review Letters  
When a core level is excited by circularly polarized light, the angular momentum of light is transferred to the emitted photoelectron, which can be confirmed by the parallax shift of the forward focusing peak (FFP) direction in a stereograph of atomic arrangement. No angular momentum has been believed to be transferred to normal Auger electrons resulting from the decay process filling core hole after photoelectron ejection. We succeeded in detecting a non-negligible circular dichroism contrast

Moreover, we detected angular-momentum-polarized Cu L 3 M 4;5 M 4;5 Auger electrons at the L 3 absorption threshold, where the excited core electron is trapped at the conduction band. From the kinetic energy dependence of the Auger electron FFP parallax shift, we found that the angular momentum is transferred to the Auger electron most effectively in the case of the 1 S 0 two-hole creation.
