Glutathione accelerates sodium channel inactivation in excised rat axonal membrane patches [PDF]
The effects of glutathione were studied on the gating behaviour of sodium channels in membrane patches of rat axons. Depolarizing pulses from –120 to –40 mV elicited sodium currents of up to 500 pA, indicating the simultaneous activation of up to 250 ...

Inactivated smallpox vaccine. A comparison of inactivation methods [PDF]
Vaccines were prepared from a single pool of high-titred vaccinia virus and inactivated by six methods, namely heat, formalin, hydroxylamine, β-propiolactone, ultraviolet irradiation, and visible light and methylene blue. Large doses of the vaccines were required to protect mice against intracerebral challenge.

Cys25‐nitrosylation inactivates papain [PDF]
AbstractNitric oxide (NO) may modulate the catalytic activity of cysteine proteases. In the present study, the inhibitory effect of NO, released by the NO‐donors (±)‐(E)‐4‐ethyl‐2‐[(E)‐hydroxyimino]‐5‐nitro‐3‐hexenamide and nitroprusside, on papain action is reported.

Comparative Study of Blue Light with Ultraviolet (UVC) Radiation on Betacoronavirus 1
The ongoing coronavirus pandemic requires more effective disinfection methods. Disinfection using ultraviolet light (UV), especially longer UVC wavelengths, such as 254 and 270/280 nm, has been proven to have virucidal properties, but its adverse effects

The effect of different frequencies of ultrasound on the activity of horseradish peroxidase [PDF]
Ultrasound technology has been studied by food researchers as an alternative method for thermal processing. The use of ultrasound as a way to inactivate and/or activate enzymes has been widely studied at low frequencies (20–40 kHz), however, little ...
