Lung surfactant alterations in pulmonary thromboembolism
Beside neonatal respiratory distress syndrome, secondary surfactant deficiency may occur in patients with mature lungs. Recent studies revealed quantitative and qualitative changes of lung surfactant in pulmonary thromboembolism (PTE) concerning the ...

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
