In the current study we evaluated protective efficacy of non-adjuvanted Newcastle disease virus (LaSota strain) Three NDV were used to vaccinate three groups chickens. same immunizations administere...

Changes in the level of a testis-specific hsp70 gene-related transcript (hst70 RNA) and its cellular localization during the cycle of rat seminiferous epithelium have been investigated. Segments of seminiferous tubules at defined stages of the cycle were isolated in living condition by transillumination-assisted microdissection and the exact stages identified by phase-contrast microscopy of liv...
