Two bacterial strains, IFM 10211(T) and IFM 10200(T), were isolated from the sputum of two Japanese patients, and were subjected to a polyphasic taxonomic study. The two strains were found to have morphological, physiological and chemotaxonomic properties that were consistent with their assignment to the genus Gordonia, except for a few chemotaxonomic characteristics. Almost complete 16S rRNA gene sequences of the two strains were determined; the data showed that they are related distantly to Gordonia ...

We previously identified a gene encoding a putative GTPase, GTPBP1, which is structurally related to elongation factor 1alpha, a key component of protein biosynthesis machinery. The primary structure of GTPBP1 is highly conserved between human and mouse (97% identical at the amino acid level). Expression of this gene is enhanced by gamma interferon in a monocytic cell line, THP-1. Although counterparts of this molecule in Caenorhabditis elegans and Ascaris suum have also been identified, the function ...

The purpose of our study was to assess whether intrahepatic spontaneous retrograde portal flow in patients with cirrhosis of the liver can be reversed to a normal portal venous flow by food intake.Of the 18 cirrhotic patients with intrahepatic spontaneous retrograde portal flow, 16 (89%) showed a marked change in portal flow direction after food intake. This evidence strongly suggests that intrahepatic spontaneous retrograde portal flow may be reversible. Furthermore, this finding implies that regular ...

In this study changes in plasma oxytocin levels were determined before and after ejaculation in patients with abnormal spermatogenesis. Plasma oxytocin levels rose significantly after ejaculation (P < 0.001, n = 17). There was no obvious correlation between plasma oxytocin levels and sperm count, sperm motility or the number of abnormal forms. Oxytocin may play a role in the precipitation of ejaculation in males.

The genomic structure of a human glycophorin variant, Miltenberger class V-like molecule (MiV*), was examined. Southern blot analysis of total genomic DNA revealed that the 5' half of the MiV* gene derived from glycophorin A (GPA) gene whereas the 3' half derived from glycophorin B (GPB) gene. This structure is reciprocal to another glycophorin variant, Sta, which has a GPB-GPA hybrid structure. The genomic sequences around the crossing-over point were amplified by polymerase chain reaction, and the ...

In our previous report, we described the structural organizations of glycophorin A and B genes (Kudo, S., and Fukuda, M. (1989) Proc. Natl. Acad. Sci. U.S.A. 86, 4619-4623). During the course of isolation of these genomic clones, we also obtained genomic clones encoding a novel glycophorin. This novel glycophorin, termed glycophorin E (GPE), has a similar genomic structure to that of the GPB gene, and its nucleotide sequence is almost identical to that of the GPB gene. These sequences include a region ...

One of the human glycophorin variants, Stones (Sta), has been shown to be the product of a hybrid gene of which the 5'-half derived from the glycophorin B (GPB) gene whereas the 3'-half derived from the glycophorin A (GPA) gene. The present study reveals the crossing-over point of this hybrid gene from the analysis of polymerase chain reaction products. The genomic sequences encompassing the region corresponding to exon 3 to exon 4 of GPA were amplified by polymerase chain reaction with oligonucleotide ...

Glycophorins A (GPA) and B (GPB) are two major sialoglycoproteins of the human erythrocyte membrane. Here we present a comparison of the genomic structures of GPA and GPB developed by analyzing DNA clones isolated from a K562 genomic library. Nucleotide sequences of exon-intron junctions and 5' and 3' flanking sequences revealed that the GPA and GPB genes consist of 7 and 5 exons, respectively, and both genes have greater than 95% identical sequence from the 5' flanking region to the region approximately ...

Rett syndrome (RTT) is an X chromosome-linked neurodevelopmental disorder associated with the characteristic neuropathology of dendritic spines common in diseases presenting with mental retardation (MR). Here, we present the first quantitative analyses of dendritic spine density in postmortem brain tissue from female RTT individuals, which revealed that hippocampal CA1 pyramidal neurons have lower spine density than age-matched non-MR female control individuals. The majority of RTT individuals carry ...

The expression of the methylated DNA-binding protein MeCP2 increases during neuronal development, which suggests that this epigenetic factor is crucial for neuronal terminal differentiation. We evaluated dendritic and axonal development in embryonic day-18 hippocampal neurons in culture by measuring total length and counting branch point numbers at 4 days in vitro, well before synapse formation. Pyramidal neurons transfected with a plasmid encoding a small hairpin RNA (shRNA) to knockdown endogenous ...

Human leukosialin (CD43) is a major sialoglycoprotein expressed on leukocytes and platelets. In order to investigate the transcriptional regulation of this gene, we have isolated a genomic DNA of 12 kilobases in size that includes the 5'-flanking sequence. Comparison of the genomic and cDNA sequences revealed that the leukosialin gene consists of two exons, and that its entire translation product is encoded in the second exon. The transcriptional start site was determined by primer extension analysis ...

The swelling equilibrium behaviour of N-n-butyl-N,N-dimethyl-4-vinyl benzylammonium bromide (BBABr) gel was measured in aqueous solutions of various inorganic electrolytes: HBr, LiBr, NaBr, KBr, NH4Br, NaCl, NaI and NaClO4. The equilibrium swelling volume of BBABr gel does not depend strongly on the cationic species but on the anionic species. In aqueous solutions containing I− and ClO−4 ions, the volume-phase transitions of the BBABr gel were induced by a change in the concentration of the electrolytes. ...

Abstract Although MECP2 was initially identified as the causative gene in classic Rett syndrome (RTT), the gene has now been implicated in several phenotypes that extend well beyond the clinically defined disorder. MECP2 mutations have been found in people with various disorders, including neonatal onset encephalopathy, X‐linked recessive mental retardation (MRX), classic and atypical RTT, autism, and Angelman syndrome, as well as mildly affected females and normal carrier females. To make matters ...
