The invention relates to compositions of erythrocytes that have been modified following hypotonic lysis and resealing by addition of 2',3'-dideoxycytidine-5'-triphosphate (ddCTP) or 3'-azido-3'-deoxythymidine-5'-triphosphate (AZT-TP). These compositions may also contain ATP. Also disclosed are methods of preparing these compositions.

Use of the tetramerous derivative of indole-3-carbinol having formula I for preparing a medicinal having anti-carcinogenic activity, and method of synthesis of the tetramerous derivative having formula I, in which indole-3-carbinol is reacted with an oxidizing agent so as to cause a polymeric oxidation of indole-3-carbinol.
摘要:
A panoramic periscope includes a central body (3, 3A) and a rotating head-piece (9) supported on the central body. Inside the central body, an optical path (21, 23, 101, 105, 109, 111, 113) for an optical beam (F,) coming from the head-piece (9) is provided. A viewing module (17) receives the optical beam, for observing the external scenery. A laser telemeter (19) is provided and, along the optical path, a separator element (10S) with an inner dichroic surface (105A) is passed through by the optical beam coming from the head-piece (9). The inner dichroic surface (105A) separates a laser beam coming from the head-piece (9) and deviating it towards a separate optical path (107) which conveys the laser beam towards the laser telemeter (19). The separator element (105) has an entry surface (105I) and an exit surface (105U) which are parallel with one another and passed through by the optical beam (FV), the surfaces being perpendicular to the optical beam (FV). The internal dichroic surface (105A) is oriented, with respect to the entry surface (105I) so that the laser beam is reflected by the dichroic surface (105A) towards the entry surface (105I) at an angle so as to be reflected entirely by the entry surface (105I) towards a surface (105L) for exiting of the laser beam.
摘要:
An infrared image sensor, in particular one of the interlaced parallel scanning type, is described. The infrared image sensor has an optical focusing system for focusing an image on a matrix of sensitive elements (55) for the detection of the image. A collimator unit (5) forms a focal plane. The collimator unit is disposed at the entry of the sensor. At least one thermal reference (33), whose image is projected on the matrix (55), is disposed on the optical path of the image inside the sensor.
