Comparisons of F factors and R factors: existence of independent regulation groups in F factors.
The similarity of sex pili mediated by F factors and R(fi(+)) factors and the ability of R(fi(+)) factors to control by repression the functioning of pilus genes encoded by the F factor suggested that F factors and R(fi(+)) factors are closely related. Further comparisons of the episomal properties of F factors and R(fi(+)) factors, however, indicated many differences. F factors contain informa...
متن کاملMechanisms of antibiotic resistance determined by resistance-transfer factors.
Unowsky, Joel (Northwestern University Medical School, Chicago, Ill.), and Martin Rachmeler. Mechanisms of antibiotic resistance determined by resistance-transfer factors. J. Bacteriol. 92:358-365. 1966.-This study was concerned with the mechanism of expression of drug resistance carried by resistance-transfer (R) factors of two types: fi(-) (negative fertility inhibition) and fi(+) (positive f...
متن کاملResearch and fertility regulation.
Research into family planning becomes all the more important when evidence indicates that demographic profiles have changed over time in populations using contraceptive methods. For example, in some countries that have successfully introduced large-scale fertility-regulating methods, the population is still expected to double in less than 30 years. Such is the case of Bangladesh, where most of ...
متن کاملMale Fertility Factors
Since the early 60s, in our lab we sought useful correlations of seminal traits and fertility in order to ultimately predict the reproductive outcome of bovine semen used in artificial breeding or the fertility of a specific male under natural service. Despite these efforts, to this day we can only account for approximately 50-60% of the variation in fertility among males by measuring seminal t...
متن کاملConnectionist F - structure Transfer
A traditional transfer system in machine translation maps between language structures and an intermediate representation. Our connectionist transfer system maps from f-structures of one language to f-structures of another language. It encodes the intermediate representation implicitly in neural networks' activation patterns. The system is learnable, therefore it does not need any e ort in handc...
