Article Synopsis
- EPS (Extracellular polymeric substances) surround microbes and are important for various environmental processes, but their role in bacterial disinfection is not well understood.
- Researchers created an EPS-deficient strain of a known EPS-producing pathogen to study how the absence of EPS affects bacterial survival during disinfection with agents like ozone, chloramine B, and free chlorine.
- The study found that removing EPS significantly increased bacterial sensitivity to disinfectants, improving disinfection efficiency and revealing EPS as a key factor in bacterial defense mechanisms.

Objective: To investigate the effects of sinusoidal magnetic field on isolated sarcoplasmic reticulum (SR) calcium release channel (RyR1) function.
Methods: With the Ca2+ dynamic spectrum and isotope labeled methods, the Ca2+ release and [(3)H]-Ryanodine binding, the initial rates of NADH oxidation and the production of superoxide of SR exposed to 50 Hz sinusoidal magnetic field (MF) were investigated respectively.
Results: 0.

Objective: To investigate the effects of power frequency magnetic field on the Ca2+ transport dynamics of isolated sarcoplasmic reticulum vesicles.
Methods: The assays of Ca2+ uptake time course and the Ca2+-ATPase activity of sarcoplasmic reticulum vesicles were investigated by using dynamic mode of spectrometry with a Ca2+ dye; Ca2+ release channel activation was examined by 3H-ryanodine binding and Ca2+ release assays; membrane fluidity of sarcoplasmic reticulum vesicles was examined by fluorescence polarization, without or with exposure to the vesicles at a 0.4 mT, 50 Hz sinusoidal magnetic field.
