Expression and DNA methylation of the Moloney murine leukemia virus (M-MuLV) genome were investigated in murine teratocarcinoma cells after virus infection. The newly acquired viral genome was devoid of methylation, yet its expression was repressed. The integrated viral genome in undifferentiated teratocarcinoma cells was methylated within 15 days after(More)
Botulinum toxin type A (BoNT/A) produced by Clostridium botulinum inhibits Ca2+-dependent acetylcholine (ACh) release (neuroexocytosis) at peripheral neuromuscular junctions, sometimes causing neuromuscular paralysis. This inhibitory effect is attributed to its metalloprotease activity to cleave the 25-kDa synaptosomal-associated protein, which is essential(More)
Regulation of cell polarity is an important biological event that governs diverse cell functions such as localization of embryonic determinants and establishment of tissue and organ architecture. The Rho family GTPases and the polarity complex Par6/Par3/atypical protein kinase C (PKC) play a key role in the signaling pathway, but the molecules that regulate(More)
Gene mutation of tubulin alpha-1A (TUBA1A), a critical component of microtubules of the cytoskeleton, impairs neural migration and causes lissencephaly (LIS). The approximately 45 cases of disease-associated TUBA1A mutations reported to date demonstrate a wide spectrum of phenotypes. Here we describe an 8-year-old girl with lissencephaly, microcephaly, and(More)
STUDY DESIGN Controlled laboratory study, technical note. OBJECTIVES The purpose of this study was to quantify changes in the thickness of the transversus abdominis, internal oblique, and external oblique muscles induced by different inward pressures of the transducer during ultrasound imaging (USI). BACKGROUND USI of the lateral abdominal muscles is(More)
The abdominal drawing-in maneuver (ADIM) is commonly used as a fundamental component of lumbar stabilization training programs. One potential limitation of lumbar stabilization programs is that it can be difficult and time consuming to train people to perform the ADIM. The transverse abdominis (TrA), internal oblique (IO), and external oblique (EO) muscles(More)
Dynamic rearrangements of cell-cell adhesion underlie a diverse range of physiological processes, but their precise molecular mechanisms are still obscure. Thus, identification of novel players that are involved in cell-cell adhesion would be important. We isolated a human kelch-related protein, Kelch-like ECT2 interacting protein (KLEIP), which contains(More)
Prone hip extension (PHE) is commonly used in the evaluation of the stability of the lumbopelvic region. There is little evidence of difference in muscle activity onset timing between healthy individuals and individuals with chronic low back pain (CLBP) during PHE. The purpose of this study was to determine if individuals with and without CLBP differ in the(More)
Measles virus (MV) is the causative agent for acute measles and subacute sclerosing panencephalitis (SSPE). Although numerous mutations have been found in the MV genome of SSPE strains, the mutations responsible for the neurovirulence have not been determined. We previously reported that the SSPE Osaka-2 strain but not the wild-type strains of MV induced(More)
Colony-forming eutrophic marine microorganisms in ballast water were counted in samples taken on board in 2002 and 2003. In the ballast water in Japan, viable cell numbers were highly variable but not by more than 10(5.1) colony-forming units (CFU)ml(-1) regardless of season. Even when ballast water was discharged offshore, values varied but not by more(More)
