摘要:
Agencement servant à inhiber les effets adverses, sur un organisme vivant, d'un champ ambiant variable dans le temps, qui présente une composante électrique égale ou inférieure à 5 Kv/M, et/ou une composante magnétique égale ou inférieure à 500 muT. Afin de conférer une protection à cet organisme, au moins l'un des paramètres caractéristiques dudit champ auquel est exposé cet organisme vivant, est modifié à des intervalles de temps inférieurs à 10 secondes.
摘要:
Anti-malarial compositions for prophylactic or therapeutic treatment of vertebrates exposed to malaria parasites are disclosed. These compositions comprise one or more pyrimidine analogue inhibitors of nucleic acid biosynthesis, e.g., 5-fluoro-orotic acid, alone or together with one or more "rescue" compounds, e.g., a normal pyrimidine base or nucleoside that can be used by the host vertebrate, but not by malaria-causing parasites, for nucleic acid biosynthesis. Also claimed are methods of prophylactic and therapeutic use of these compositions.
摘要:
Described is an "artificial virus" (AV) programmed with biomolecules that can enter human cells and carry out precise human genome modification. The AVs comprise: at least one viral vector, such as bacteriophage T4; at least one therapeutic molecule, such as DNA, RNA, protein and their complex; and a lipid coating. Also described is a method of human genome modification, using such an AV, and a method of program such an AV.
摘要:
Complex viruses are assembled from simple protein subunits by sequential and irreversible assembly. During genome packaging in bacteriophages, a powerful molecular motor assembles at the special portal vertex of an empty prohead to initiate packaging. An aspect of the invention relates to the phage T4 packaging machine being highly promiscuous, translocating DNA into finished phage heads as well as into proheads. Single motors can force exogenous DNA into phage heads at the same rate as into proheads and phage heads undergo repeated initiations, packaging multiple DNA molecules into the same head. This shows that the phage DNA packaging machine has unusual conformational plasticity, powering DNA into an apparently passive capsid receptacle, including the highly stable virus shell, until it is full. These features allow for the design of a novel class of nanocapsid delivery vehicles.
