Photodynamic detection of a canine glioblastoma using 5‐aminolevulinic acid

M. Yamashita, T. Osaki, Y. Sunden, K. Takahashi, more

Journal of Small Animal Practice > 61 > 8 > 516 - 519

Photodynamic detection using 5‐aminolevulinic acid has been used to identify the surgical margins during resection of human primary brain tumours. Although there are some reports on its use in malignant tumours in veterinary medicine, it has never been used for primary brain tumours. Here we describe a canine glioblastoma that was detected at autopsy with protoporphyrin IX fluorescence induced by...

A primary canine and an impacted permanent canine with infection potentially induced an intracranial abscess

E Nagata, T Nishiyama, M Yamashita, T Ishigami, more

Australian Dental Journal > 65 > 1 > 96 - 99

Intracranial abscess is a rare but life‐threatening disease. There have been no reports on intracranial abscess induced by the residual primary tooth and the impacted successive permanent tooth with infection. We report on an interesting case of a 29‐year‐old man suffering from an epidural abscess, potentially caused by an infection of the residual primary maxillary right canine and the impacted permanent...

Effects of paraoxonase 1 on the cytodifferentiation and mineralization of periodontal ligament cells

R. Masumoto, J. Kitagaki, M. Matsumoto, S. Miyauchi, more

Journal of Periodontal Research > 53 > 2 > 200 - 209

Background and Objective Single nucleotide polymorphisms (SNPs) of paraoxonase 1 (PON1) are known to be associated with the pathogenesis of osteoporosis and periodontitis. However, the effects of PON1 on the osteoblastic differentiation of periodontal ligament (PDL) cells are unclear. In this study, we examined the effects of PON1 on the osteoblastic differentiation of PDL cells, and analysed the...

Stay Connected: A Germ Cell Strategy

Kevin Lu, Lindy Jensen, Lei Lei, Yukiko M. Yamashita

Trends in Genetics > 2017 > 33 > 12 > 971-978

Germ cells develop as a cyst of interconnected sibling cells in a broad range of organisms in both sexes. A well-established function of intercellular connectivity is to transport cytoplasmic materials from ‘nurse’ cells to oocytes, a critical process for developing functional oocytes in ovaries of many species. However, there are situations where connectivity exists without a nursing mechanism, and...

Detectability of galactic supernova neutrinos coherently scattered on xenon nuclei in XMASS

K. Abe, K. Hiraide, K. Ichimura, Y. Kishimoto, more

Astroparticle Physics > 2017 > 89 > C > 51-56

The coherent elastic neutrino-nucleus scattering (CEvNS) plays a crucial role at the final evolution of stars. The detection of it would be of importance in astroparticle physics. Among all available neutrino sources, galactic supernovae give the highest neutrino flux in the MeV range. Among all liquid xenon dark matter experiments, XMASS has the largest sensitive volume and light yield. The possibility...

The ins(ide) and outs(ide) of asymmetric stem cell division

Cuie Chen, Jaclyn M Fingerhut, Yukiko M Yamashita

Current Opinion in Cell Biology > 2016 > 43 > C > 1-6

Many adult stem cells divide asymmetrically, generating one stem cell (self-renewal) and one differentiating cell. Balancing self-renewal and differentiation is critical for sustaining tissue homeostasis throughout the life of an organism. Failure to execute asymmetric stem cell division can have profound impacts on tissue homeostasis, resulting in tissue degeneration or hyperplasia/tumorigenic overgrowth...

Lung remodeling associated with recovery from acute lung injury

Sean E. Gill, Cory M. Yamashita, Ruud A. W. Veldhuizen

Cell and Tissue Research > 2017 > 367 > 3 > 495-509

Acute respiratory distress syndrome (ARDS) is a disease with a variety of causes and is defined by severe hypoxemia. Whereas ARDS carries a mortality of approximately 30 %, patients that survive may ultimately regain near normal pulmonary physiology. The critical pathophysiological processes in ARDS are alveolar barrier dysfunction and overwhelming inflammation. This encompasses damage to the epithelial...

A measurement of the time profile of scintillation induced by low energy gamma-rays in liquid xenon with the XMASS-I detector

H. Takiya, K. Abe, K. Hiraide, K. Ichimura, more

Nuclear Instruments and Methods in Physics Research Section A: Accelerators,... > 2016 > 834 > C > 192-196

We report the measurement of the emission time profile of scintillation from gamma-ray induced events in the XMASS-I 832kg liquid xenon scintillation detector. Decay time constant was derived from a comparison of scintillation photon timing distributions between the observed data and simulated samples in order to take into account optical processes such as absorption and scattering in liquid xenon...

Keeping stem cells under control: New insights into the mechanisms that limit niche‐stem cell signaling within the reproductive system

Mayu Inaba, Yukiko M. Yamashita, Michael Buszczak

Molecular Reproduction and Development > 83 > 8 > 675 - 683

Adult stem cells reside in specialized microenvironments, called niches, that maintain stem cells in an undifferentiated and self‐renewing state. Defining and understanding the mechanisms that restrict niche signaling exclusively to stem cells is crucial to determine how stem cells undergo self‐renewal while their progeny, often located just one cell diameter away from the niche, differentiate. Despite...

Direct dark matter search by annual modulation in XMASS-I

K. Abe, K. Hiraide, K. Ichimura, Y. Kishimoto, more

Physics Letters B > 2016 > 759 > C > 272-276

A search for dark matter was conducted by looking for an annual modulation signal due to the Earth's rotation around the Sun using XMASS, a single phase liquid xenon detector. The data used for this analysis was 359.2 live days times 832 kg of exposure accumulated between November 2013 and March 2015. When we assume Weakly Interacting Massive Particle (WIMP) dark matter elastically scattering on the...

Search for two-neutrino double electron capture on 124Xe with the XMASS-I detector

K. Abe, K. Hiraide, K. Ichimura, Y. Kishimoto, more

Physics Letters B > 2016 > 759 > C > 64-68

Double electron capture is a rare nuclear decay process in which two orbital electrons are captured simultaneously in the same nucleus. Measurement of its two-neutrino mode would provide a new reference for the calculation of nuclear matrix elements whereas observation of its neutrinoless mode would demonstrate lepton number violation. A search for two-neutrino double electron capture on ¹²⁴Xe is...

Signaling by Cellular Protrusions: Keeping the Conversation Private

Michael Buszczak, Mayu Inaba, Yukiko M. Yamashita

Trends in Cell Biology > 2016 > 26 > 7 > 526-534

Information exchange between different cells makes multicellular life possible. Signaling between cells can occur over long distances, as in the case of hormone signaling, or it can take place over short distances between immediately juxtaposed neighbors, as in the case of stem cell-niche signaling. The ability of signal-sending and -receiving cells to communicate with one another in a specific manner...
