Levy, Stuart B. (Institut du Radium, Paris, France). Isologous interference with ultraviolet and X-ray irradiated bacteriophage T(2). J. Bacteriol. 87:1330-1338. 1964.-Qualitative and quantitative analysis of the interference capacity of an irradiated T(2) bacteriophage was made with ultraviolet and X-ray irradiation. Two different effects were found to explain the total interference picture in...

New loci of replication along the bacterial chromosome are observed after irradiation of Escherichia coli. It was conjectured that, after X-irradiation, the new initiation site was random with respect to the fixed-origin, whereas, after ultraviolet light exposure, it was selective and appeared to be from the fixed-origin. Evidence presented here shows that, after X-irradiation of E. coli, the n...

An ultraviolet radiation-sensitive derivative of Streptococcus faecalis strain JH2-2 was isolated and found to be deficient in recombination, using a plasmid-plasmid recombination system. The strain was sensitive to chemical agents which interact with deoxyribonucleic acid and also underwent deoxyribonucleic acid degradation after ultraviolet irradiation. Thus, the mutant has properties similar...

Allyl phenyl ether has an absorption band in the ultraviolet region (l o 400 nm); therefore, irradiation with few-optical-cycle ultraviolet pulses (l = 360–440 nm) causes a transition to the ultraviolet band, which leads to an electronic state and a photo-Claisen rearrangement (radical reaction) in the electronic excited state. However, the reaction scheme of allyl phenyl ether under irradiatio...

Chloramphenicol is known to inhibit protein synthesis in different microorganisms without affecting the syntheses of nucleic acids (Gale and Folkes, 1953; Wisseman et al., 1954; Aronson and Spiegelman, 1958). Harold and Ziporin (1958) and Drakulic and Errera (1959) reported that the treatment of Escherichia coli with chloramphenicol immediately after ultraviolet irradiation prevented the resump...

Myopic individuals, especially those with severe myopia, are at higher-than-normal risk of cataract, glaucoma, retinal detachment and chorioretinal abnormalities. In addition, pathological myopia is a common irreversible cause of visual impairment and blindness. Our study demonstrates the effect of scleral crosslinking using riboflavin and ultraviolet-A radiation on the development of axial myo...

Regarding the influence of ultraviolet irradiation on the growth of bacteria, numerous studies have been accomplished and it has been known that there exists a relation of exponential function between the bactericidal effect and the amount of ultraviolet ray irradiated. The methods employed in those studies,1),2),3),4) a,b, however, are mostly so called plate method in which the irradiation is ...

Recently, TiO2/multi-walled carbon nanotube (MWCNT) hybrid nanocatalysts have been a subject of high interest due to their excellent structures, large surface areas and peculiar optical properties, which enhance their photocatalytic performance. In this work, a modified microwave technique was used to rapidly synthesise a TiO2/MWCNT nanocatalyst with a large surface area. X-ray powder diffracti...
