Targeted Deletion of the Cytopathogenic Toxin A Gene in Sneathia vaginalis

open access: yesMolecular Microbiology, Volume 124, Issue 6, Page 481-490, December 2025.
Sneathia vaginalis is emerging as an important marker for preterm birth. Through this study, we developed a method for site‐directed mutagenesis in this species. The gene encoding the cytopathogenic toxin A (CptA) was deleted as a proof of principle, and the deletion mutant revealed that CptA is indispensable for the cytotoxic and hemolytic activities ...

Stereoscopic Quantitative Analysis of Enteric Nervous System in Patients With Slow Transit Constipation

open access: yesNeurogastroenterology &Motility, Volume 37, Issue 12, December 2025.
This study used a stereoscopic imaging method that combines tissue clearance, immunohistochemistry, and confocal imaging techniques to construct a quantifiable three‐dimensional view of the enteric nervous system, accurately evaluating changes in the enteric nervous system of patients with slow transit constipation.

Molecular Evolution and Epidemiology of Benyviridae and the Agricultural Implications

open access: yesPlant Pathology, Volume 74, Issue 9, Page 2478-2491, December 2025.
This study reveals Benyvirus diversity and evolution, highlighting their agricultural impact and the need for molecular surveillance to manage emerging plant viral diseases. ABSTRACT Viruses from the Benyviridae family are important aetiological agents of diseases in plants and are responsible for significant losses in agricultural production across ...

Perturbed angular correlation study of a haptenic molecule [PDF]

open access: yes, 1972
The angular correlation of the 173-247 keV gamma-ray cascade after the electron-capture decay of (111)In is strongly perturbed when the I-p-nitrophenylethylenediaminetetraacetate chelate of (111)In(3+) is added to a solution containing rabbit antibody ...

Differential laboratory passaging of SARS-CoV-2 viral stocks impacts the in vitro assessment of neutralizing antibodies.

open access: yesPLoS ONE
Viral populations in natural infections can have a high degree of sequence diversity, which can directly impact immune escape. However, antibody potency is often tested in vitro with a relatively clonal viral populations, such as laboratory virus or ...

Non-Measles Hemadsorption in a Cell Line Persistently Infected with Measles Virus (BGM/MV) [PDF]

open access: yes, 1981
Adsorption of Rhesus monkey erythrocytes to the plasma membranes of measles virus infected cells is frequently carried out to detect the presence of plasma membrane-associated measles virus hemagglutinin.

On the unlikelihood of specific long range forces in immunologic and enzymatic reactions [PDF]

open access: yes, 1950
In the past few years, a great many experiments have been performed by Rothen (24, 25) which he has interpreted as suggesting that antigen and antibody, and enzyme and substrate proteins, can react specifically, although separated by distances of ...

Characterization of the Lipopolysaccharide from a \u3cem\u3eRhizobium phaseoli\u3c/em\u3e Mutant that is Defective in Infection Thread Development [PDF]

open access: yes, 1987
The lipopolysaccharide (LPS) from a Rhizobium phaseoli mutant, CE109, was isolated and compared with that of its wild-type parent, CE3. A previous report has shown that the mutant is defective in infection thread development, and sodium dodecyl sulfate ...
