Plasmid‐Mediated Sulfanilamide Resistance [PDF]

open access: yesMicrobiology and Immunology, 1978
AbstractDihydropteroate synthetase (DHPS) is specified by a substrain of Escherichia coli K12, ML1410. This enzyme activity is inhibited by sulfanilamides (Sa) and is known to be heat‐stable, i.e., an Sa‐sensitive normal enzyme. Another DHPS activity specified by E. coli ML1410 carrying drug resistance plasmids is Sa‐resistant but heat‐sensitive, i.e.,

SR‐B1‐Mediated Transplacental Transfer of Hydrophobic Toxicants Disrupts Fetal Development During Barriergenesis

open access: yesAdvanced Science, EarlyView.
This study maps the spatiotemporal distribution of hydrophobic toxicants and endogenous metabolites in the developing placenta and fetus. By integrating mass spectrometry imaging with snRNA‐seq, we identify SR‐B1 as a key transporter driving early‐gestation xenobiotic transfer and reveal a critical exposure window associated with persistent fetal ...
