A bacterium capable of degrading microcystins-RR, -YR, and -LR was isolated from a hypertrophic lake. The bacterium, designated Y2 and classified phenotypically as a member of the genus Sphingomonas,… Expand
Nuclear Transport of the Major Capsid Protein Is Essential for Adeno-Associated Virus Capsid Formation
ABSTRACT Adeno-associated virus capsids are composed of three proteins, VP1, VP2, and VP3. Although VP1 is necessary for viral infection, it is not essential for capsid formation. The other capsid… Expand
Characterization of self-assembled virus-like particles of human polyomavirus BK generated by recombinant baculoviruses.
The major structural protein of the human polyomavirus BK (BKV), VP1, was expressed by using recombinant baculoviruses. A large amount of protein with a molecular mass of about 42 kDa was synthesized… Expand
Helicobacter pylori infection prevents erosive reflux oesophagitis by decreasing gastric acid secretion
BACKGROUND Helicobacter pylori infection is less prevalent and atrophic gastritis is less extensive in patients with reflux oesophagitis than those without it, but few studies have examined this… Expand
Structural analysis of vaccinia virus DIs strain: application as a new replication-deficient viral vector.
DIs is a restrictive host range mutant of vaccinia virus strain DIE that grows well only in chick embryo fibroblast cells but is unable to grow in most mammalian cells. In this study, we identified… Expand
Serum Immunoglobulin G Antibody To Periodontal Bacteria
The purpose of this study was to assess the serum antibody levels to periodontal bacteria in patients with periodontal disease, and to explore the diagnostic uses of the serum antibody assessment and… Expand
Evolution and Biological Characterization of Human Immunodeficiency Virus Type 1 Subtype E gp120 V3 Sequences following Horizontal and Vertical Virus Transmission in a Single Family
ABSTRACT It has been suggested that immune-pressure-mediated positive selection operates to maintain the antigenic polymorphism on the third variable (V3) loop of the gp120 of human immunodeficiency… Expand
Changes in gastric acid secretion assayed by endoscopic gastrin test before and after Helicobacter pylorieradication
BACKGROUND It remains controversial whether or not Helicobacter pyloriinfection causes altered gastric acid secretion. A novel test for evaluating gastric acid secretion (endoscopic gastrin test;… Expand
Recombinant hepatitis E capsid protein self-assembles into a dual-domain T = 1 particle presenting native virus epitopes.
The three-dimensional structure of a self-assembled, recombinant hepatitis E virus particle has been solved to 22-A resolution by cryo-electron microscopy and three-dimensional image reconstruction.… Expand
Detection of JC virus in the brains of aged patients without progressive multifocal leukoencephalopathy by the polymerase chain reaction and Southern hybridization analysis
Ninety-one brain tissue sections taken at autopsy from 33 elderly patients (63-100 years old) without progressive multifocal leukoencephalopathy were examined for the presence of JC virus DNA by the… Expand
