Response to wing-web challenge (WWC) of Rous sarcoma virus (RSV) subgroups was studied in 4-8 weeks old chicks of a light breed, a heavy breed and a cross between an indigenous black plumage Bantam fowl and Australorp breed. Wing-web tumor (WWT) began to develop within one week in response to virus subgroups A (BS-RSV) and C [RSV (RAV-49)] challenge. In chicks challenged with subgroup D [RSV (R...

The molecular mechanisms regulating tissue size represent an unsolved puzzle in developmental biology. One signalling pathway controlling growth of the Drosophila wing is Dpp. Dpp promotes growth by repression of the transcription factor Brk. The transcriptional targets of Brk that control cell growth and proliferation, however, are not yet fully elucidated. We report here a genome-wide ChIP-Se...

To adjust breeding programs for local, commercial, and fancy breeds, to implement molecular (marker-assisted) breeding, a proper comprehension of phenotypic genotypic variation is sine qua non progress in animal production. Here, we investigated an evolutionary subdivision domestic chickens based on their variability using wide sample 49 different breeds/populations. These represent significant...

The first commercially successful F1 hybrid sweet corn, Golden Cross Bantam, was released by Smith in the early 1930s (17). Today, over 600 sweet corn hybrids are available commercially in the United States and thousands of new hybrids are developed and evaluated each year. These hybrids display a wide range of phenotypic reactions to prevalent diseases (9), indicating a considerable amount of ...

The purpose of this study is to examine modern professional male boxing by analyzing world champions differences between winners and losers categories. 322 boxers (age 28.95 ± 4.10, height 175.26 9.44 cm, weight 147.82 31.31 lb) were included in observational descriptive analysis, through 320 fights separated divisions [Heavy (H) (n = 24), Cruiser (C) 48), Light Heavy (LH) 62), Super Middle Wei...
