The labels were designed in response to the problem of delivering vaccines to developing countries where the cold chain is difficult to preserve, and where formerly vaccines were being rendered inactive and administered ineffectively due to their having been denatured by exposure to ambient temperature.Total internal reflection fluorescence microscope: A total internal reflection fluorescence microscope (TIRFM) is a type of microscope with which a thin region of a specimen, usually less than 200 nm can be observed.Sertoli cell nodule: A Sertoli cell nodule, also Pick's adenoma, testicular tubular adenoma and tubular adenoma of the testis, is a benign proliferation of Sertoli cells that arises in association with cryptorchidism (undescended testis).
