Ion current density profile of laser ablation plasma transported in multicusp magnetic field
Laser ion sources are capable of supplying ion
beams with high current because a laser produced
plasma has initially high number density same as
that of solid. [1]..
Regional contributions through athletic lessons for elementary school children
We have provided athletic lessons for elementary school children for four years. These lessons are at the center of a project that aims to contribute to the local community. Initially, we decided on the following theme: “Have fun, learn to run fast, and stand on the Big Swan track.” To improve children’s competitive abilities, we focused on engaging them in fun activities that would lay the foundation for a life filled with sports; to motivate and engage the children, we gave them a chance to attend track meets as part of the program. This project has great potential, both as a practical approach to Track and Field instruction and as a basis for student volunteer activities in the elementary school teaching course. We believe that faculty members and students of Niigata University of Health and Welfare will be able to connect with many more children in the region through this project
Brain Alterations and Mini-Mental State Examination in Patients with Progressive Supranuclear Palsy: Voxel-Based Investigations Using 18F-Fluorodeoxyglucose Positron Emission Tomography and Magnetic Resonance Imaging
Background/Aims: The aim of this study was to compare differences in morphological and functional changes in brain regions in individual patients with progressive supranuclear palsy (PSP) and correlate their Mini-Mental State Examination (MMSE) score with anatomy and function using magnetic resonance imaging (MRI) and 18F-fluorodeoxyglucose positron emission tomography (FDG-PET). Methods: Sixteen PSP patients and 20 age-matched healthy volunteers underwent FDG-PET and 3-dimensional MRI. Gray matter, white matter and metabolic activity were compared between patients and normal controls. In addition, possible correlations between the MMSE score and brain function/anatomy were examined. Results: The PSP group had reduced cerebral glucose metabolism, and lower gray and white matter volumes in the frontal lobes and midbrain compared with normal controls. In PSP subjects, the metabolic changes observed in the PET scans were greater than the loss in gray and white matter observed in the MRI scans. The MMSE scores were positively correlated with volume and FDG uptake in the frontal lobe. Conclusion: FDG-PET is a more effective tool in the diagnosis of PSP than MRI. Atrophy and hypometabolism in the frontal lobe are as important as in the basal midbrain for differentiating PSP patients who primarily exhibit cognitive dysfunction from normal controls
Terahertz spectroscopy of NO and isotopic invariant fit of several nitric oxide isotopologs
A tunable far-infrared laser sideband spectrometer was used to investigate a
nitric oxide sample enriched in 18O between 0.99 and 4.75 THz. Regular,
electric dipole transitions were recorded between 0.99 and 2.52 THz, while
magnetic dipole transitions between the 2Pi(1/2) and 2Pi(3/2) spin-ladders were
recorded between 3.71 and 4.75 THz. These data were combined with lower
frequency data of N(18)$O (unlabeled atoms refer to (14)N and (16)O,
respectively), with rotational data of NO, (15)NO, N(17)O, and (15)N(18)O, and
with heterodyne infrared data of NO to be subjected to one isotopic invariant
fit. Rotational, fine and hyperfine structure parameters were determined along
with vibrational, rotational, and Born-Oppenheimer breakdown corrections. The
resulting spectroscopic parameters permit prediction of rotational spectra
suitable for the identification of various nitric oxide isotopologs especially
in the interstellar medium by means of rotational spectroscopy.Comment: 8 pages, 1 figure; part of the Marilyn Jacox special issue of the

The nucleotide and deduced amino acid sequences of porcine liver proline-β-naphthylamidase swEvidence for the identity with carboxylesterase
AbstractA cDNA clone for porcine liver proline-β-naphthylamidase was isolated and sequenced. The deduced amino acid sequence of 567 residues was highly homologous with those of carboxylesterases (EC 3.1.1.1) previously reported for other species. In addition, proline-β-naphthylamidase purified from porcine liver was shown to have strong activity towards p-nitrophenylacetate, a representative substrate for carboxylesterases. These results suggest that proline-β-naphthylamidase is identical with carboxylesterase

An 88-year old woman had an approximately 20mm tumor in her left breast is described. We performed partial resection of her breast under local anesthesia because of her old age and found out to be an intraductal apocrine carcinoma with necrosis and histiocyte infiltration into the stroma leasion by histological findings. We made a wrong diagnosis as it was invasive ductal carcinoma by the preoperative mammography and ultrasonography findings. It might be due to those histological view. According to the immunostaining procedure, ER was positive and PgR was negative. There are 26 cases reports of intraductal apocrine carcinoma including this case in the Japanese literature. We found only 4 cases were described about intraductal necrosis in their sentences. And 3 cases of them have succeeded in treating by breast partial resection. We examined about this case and report with analyzing those previous literature review
Laser-induced-fluorescence measurement of thermal conductivity in warm dense matter generated by pulsed-power discharge
Thermal conductivity in warm dense matter is
one of the interests for thermonuclear fusion
scenarios. Alternative inertial confinement fusion,
which is a fast ignition with applied magnetic
field [1], has been considered to improve
the coupling efficiency. The target behavior of
the fast ignition with applied magnetic field depends
on the anisotropic thermal conductivity.
The magnetic confinement fusion (MCF) [2] Up
to now, the heat load on the divertor in previous
MCF systems has been unreached parameter.
Thus, to predict properties of the divertor under
these heat loads, several experiments have been
performed using several methods[3-6]. To predict
the performance of the tungsten divertor in
MCF, we should analyze not only metallurgical
properties but also thermophysical properties of
ablated tungsten..

Molecular Serotype-Specific Identification of Streptococcus Pneumoniae using Loop-Mediated Isothermal Amplification
Over the past four decades, the incidence of meningitis caused by Haemophilus influenzae in children has decreased due to widespread vaccination against H. influenzae type b (Hib). The incidence of invasive diseases due to H. influenzae types not included in the vaccines, however, has increased. At present, there are a limited number of diagnostics available to detect non-type b H. influenzae. To address this issue, we developed a rapid, simple, and cost-effective method for detecting serotypes of H. influenzae. We designed LAMP primer sets based on published sequences for H. influenzae capsular types a, c, d, e, and f. The assay was evaluated to determine test reactivity, specificity, and sensitivity. To support its use in patients with suspected meningitis, we evaluated the detection limit of the non-Hib serotype specific LAMP assay using bacterial genomic DNA-spiked cerebrospinal fluid (CSF) specimens. The reactivity and specificity of the LAMP assays were confirmed using six serotypes and non-typeable H. influenzae strains, plus eight strains of other Haemophilus species and non-Haemophilus genera. The detection limits of the LAMP assay for capsular types a, c, d, e, and f were 102, 102, 102, 103, and 10 copies per reaction, while those of the PCR assay were 104, 104, 103, 103, and 104 genome copies per reaction, respectively. Using DNA-spiked CSF specimens, the detection limit of the LAMP assay was equivalent to that using purified DNA as the template. However, the detection limit of the PCR was reduced from 103 to 104 genome copies per reaction for serotype d and from 103 to 105 genome copies per reaction for serotype e. To the best of our knowledge, this is the first report of a serotype-specific identification assay for H. influenzae using the LAMP method. Our results suggest the potential of LAMP methods for patients with suspected meningitis in resource-limited laboratories or public health surveillance systems
