A total of 122 male Wister rats with a body weight of 250-300 g were obtained from the Experimental Animal Center of Shengjing Hospital affiliated to China Medical University and kept until animal experiments were performed.
Methods: Twenty-four adult male Wister rats (b.wt.130[+ or -]10g) were grouped and accordingly group I (control) received the normal diet, group II (treated) was given arsenic orally for 28 consecutive days as arsenic trioxide (3 mg/kgbw/rat/day) whereas group III (supplemented) received the same dose of arsenic along with ALA (25 mg/kgbw/rat/day) as oral supplement.
Hayflick first started his experiments in the Wister institute, Philadelphia on human foetal lung fibroblasts and found out that cells stop dividing after 40 to 60 cycles and then senesce.
Furthermore, ZDF rats were used for breeding with Wister rats and WBN/Kob rats, which were established to be Wistar fatty rats and WBN/Kob-Lepr (fa) rats, respectively [36-39].

Synopsis: "The Cowboy Legend: Owen Wister's Virginian and the Canadian American Ranching Frontier" by John Jennings (Associate Professor Emeritus in the Department of History at Trent University) details the evidence that Everett Johnson was the prime inspiration for Owen Wister's cowboy.
