All vehicles of the Buk-M1 (Buk-M1-2) missile system use an Argon-15A computer, as does the Zaslon radar (the first Soviet-made airborne digital computer, designed in 1972 by the Soviet Research Institute of Computer Engineering (NICEVT, currently NII Argon ). It is produced at a Kishinev plant originally named "50 Years of the USSR".   The vehicles of Buk-M2 (Buk-M2E) missile system use a slightly upgraded version of Argon-A15K. This processor is also used in such military systems as anti-submarine defense Korshun and Sova , airborne radars for MiG-31 and MiG-33 , mobile tactical missile systems Tochka , Oka and Volga . Currently, [ when? ] Argons are upgraded with the Baget series of processors by NIIP. [ citation needed ]
Most in vitro and animal experiments have suggested immunostimulatory effects; however, 1 study found a spirulina extract to be immunosuppressive. 61 Activation of monocytes and macrophages, 62 , 63 as well as augmentation of interleukin and interferon production, have been demonstrated. 64 Intestinal epithelial lymphocytes of aged mice treated with spirulina were increased compared with the control aged group. 65 A clinical study in healthy men found that oral administration of spirulina for 3 months resulted in enhanced interferon production and natural killer (NK) cell capacity. 25 An ex vivo study of NK cells from spirulina-treated healthy patients showed increased NK activity, which was confirmed by a second study in which NK cell and T-cell markers were increased by spirulina. 66 A clinical trial in elderly patients showed positive effects on anemia and immunosenescence after 6 and 12 weeks of supplementation. 67 The immunostimulatory effects appear to be largely mediated by spirulina polysaccharides. 62 , 63
Injectable steroids are injected into muscle tissue, not into the veins. They are slowly released from the muscles into the rest of the body, and may be detectable for months after last use. Injectable steroids can be oil-based or water-based. Injectable anabolic steroids which are oil-based have longer half-life than water-based steroids. Both steroid types have much longer half-lives than oral anabolic steroids. And this is proving to be a drawback for injectables as they have high probability of being detected in drug screening since their clearance times tend to be longer than orals. Athletes resolve this problem by using injectable testosterone early in the cycle then switch to orals when approaching the end of the cycle and drug testing is imminent.
