conclusions taken together, these data reveal that cellular protease of chicken liver cells allows the replication of high yields of h9n2 virus in the absence of trypsin and also cell death in the infected cells is due to necrosis. results the degree of viability was significantly reduced in infected hepatoma cells. observations of caspase activation and cell dna laddering in infected cells wer...

brucellosis is a zoonotic disease mostly transmitted to humans through consumption of unpasteurized dairy products and can lead to a systemic disease with any organ involvement. in this report, we describe a case of brucellosis-induced avascular necrosis of the hip. brucellosis was diagnosed through serological tests, and avascular necrosis of the femoral head was confirmed by pelvic mri. the p...
