Fowl Paralysis and Other Forms of the Avian Leukosis Complex
The disease called fowl paralysis, together with several other allied conditions classed together as the avian leukosis complex,^ causes a tremendous loss to the poultry industry. The paralysis form of this disease complex was first recognized in the United States along the eastern coast about 1920. During the last 20 years the avian leukosis complex has spread rapidly until few flocks of chick...

Ultrastructural studies of chick embryo cells morphological ly altered by strain MC29 avian leukosis virus revealed marked and characteristic differences from normal cells and cells al tered by infection with other avian tumor viruses. Such differ ences were manifest in part in the cytoplasm by high content of free ribosomes, poorly developed rough endoplasmic reticu lum, frequent fat droplets,...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولThe epidemiology of avian lymphoid leukosis.
Avian lymphoid leukosis can be induced by lymphoid leukosis viruses belonging to Subgroups A, B, C, and D. The endogenous virus of the chicken (Rous-associated virus type 0) belongs to Subgroup E and has little, if any, potential for inducing lymphoid leukosis. Nearly all chicken flocks are infected with Subgroup A lymphoid leukosis virus. This virus can be transmitted from dam to offspring or ...

(Continued from page 31) this pathological cycle is to raise the blood oestrogen level to that stage at which the corpus luteum regresses. This can be done by injecting 25 mg. of stilboestrol dipropionate and potentiating the uterus into rhythmic contractions by injecting posterior lobe pituitary. A similar treatment may be used in case of pyometra. (Brownlee, G. (Wellcome Physiol. Res. Lab., B...
