Multiplicity reactivation of reovirus particles after exposure to ultraviolet light.
McClain, Mary E. (California State Department of Public Health, Berkeley), and Rex S. Spendlove. Multiplicity reactivation of reovirus particles after exposure to ultraviolet light. J. Bacteriol. 92:1422-1429. 1966.-Exposure of reovirus suspensions to moderate doses of ultraviolet light results in essentially exponential inactivation of infectivity to survivals of 10(-2) to 10(-3). With suspens...
متن کاملThe use of ultraviolet light in the fractionation of chromatin containing unsubstituted and bromodeoxyuridine-substituted DNA.
Two procedures are described for the fractionation of chromatin containing unsubstituted (LL) DNA and DNA unifilarly substituted with bromodeoxyuridine (HL). The two procedures rely upon the sensitivity of bromodeoxyuridine-containing DNA to UV light to induce either strand breakage or protein crosslinking. When a mixture of LL and HL chromatin is irradiated with UV light, the HL DNA fragments ...
متن کاملThe desmosomal protein Desmoglein 1 aids recovery of epidermal differentiation after acute ultraviolet light exposure
Epidermal structure is damaged by exposure to UV light, but the molecular mechanisms governing structural repair are largely unknown. UVB (290-320 nm wavelengths) exposure before induction of differentiation reduced expression of differentiation-associated proteins, including desmoglein 1 (Dsg1), desmocollin 1 (Dsc1), and keratins 1 and 10 (K1/K10), in a dose-dependent manner in normal human ep...
متن کاملIncreased thermal stability of chromatin containing 5-bromodeoxyuridine-substituted DNA.
The replacement of thymidine by 5-bromodeoxyuridine in DNA leads to a greatly enhanced stability of chromatin from hepatoma tissue culture or embryonic rat pancreas, as measured by thermal chromatography on hydroxylapatite. The increased stability is directly correlated with the degree of bromodeoxyuridine substitution. On the other hand, the incorporation of bromodeoxyuridine into DNA results ...
متن کاملMass photokeratitis following exposure to unprotected ultraviolet light.
We report a cluster of patients developing photokeratitis as a result of exposure to unprotected UV-B light source. The incident occurred at a cattle livestock market auction where the light source protective covers of mercury vapour lamps were damaged because of vandalism. The incident was investigated by the District Council as a public health and safety issue. This report stresses the hazard...
