OBJECTIVE To compare the ability of dobutamine and dipyridamole stress echocardiography to detect functional recovery of stunned but viable myocardial regions early after acute myocardial infarction, and to predict late functional recovery of the reperfusion salvaged myocardium within the infarct area. METHODS Within 10 d of acute myocardial infarction, 51 patients--30 anterior and 21 inferio...

OBJECTIVE To evaluate the prevalence of "high-risk" human papilloma virus (HPV) types in penile condyloma-like lesions and to correlate HPV types with clinical and histological features. DESIGN The study included 94 male patients with signs of penile HPV infection. From acuminate, papular and macular lesions, specimens were collected for HPV DNA hybridisation, using the dot blot and Southern ...

Cotton fiber is an ideal model to study cell elongation and cell wall construction in plants. During fiber development, some genes and proteins have been reported to be specifically or preferentially expressed. Mapping of them will reveal the genomic distribution of these genes, and will facilitate selection in cotton breeding. Based on previous reports, we designed 331 gene primers and 164 pro...
