Differentiation of ribonucleic acids by inhibition of streptococcal deoxyribonuclease

Differentiation of ribonucleic acids by inhibition of streptococcal deoxyribonuclease.

It has been shown (Bernheimer & Ruffier, 1951 ) that physical disruption of streptococci belonging to Lancefield groups A, B, C and D results in the liberation of a substance which partially inhibits the depolymerizing action of group A streptococcal deoxyribonuclease. One of the striking characteristics of the inhibitory substance is its specificity, for although it inhibits the deoxyribonucle...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

Micro test for streptococcal anti-deoxyribonuclease B.

A methyl green decolorization micro test for the determination of streptococcal anti-deoxyribonuclease B titers in serum is described. The micro test was compared with an alcohol precipitation macro test on 112 human sera. The anti-deoxyribonuclease B titers agreed within one dilution step for 85.7% of the 112 sera examined by both techniques. Both tests were about equal in the detection of tit...
