Neuronal apoptosis has been shown to occur in HIV infection by a number of in vivo and in vitro studies, however, the cause of neuronal damage in AIDS is still unclear and its relationships with the cognitive disorders characteristic of HIV dementia remain a matter of debate. In this review, based on our experience, we analyse the techniques used to… (More)
During avian development the earliest phase in which the avian embryo expresses axial features of a left-right axis is at the primitive streak stage. Until the stage of definitive primitive streak (streak 4 H&H), the axis seems to possess morphological bilateral symmetry. Morphological asymmetry begins only during the next few hours of incubation, with… (More)
The ability to rapidly diagnose influenza virus infections is of the utmost importance in the evaluation of patients with upper respiratory tract infections. It is also important for the influenza surveillance activities performed by national influenza centers. In the present study we modified a multiplex real-time reverse transcriptase PCR (RT-PCR) assay… (More)
The influence of hearing loss on the click-evoked otoacoustic emissions (EOAE) were studied in 931 ears. The EOAEs were never found when hearing loss on the best hearing frequency was above 40 dB HL. The presence of EOAEs reflects the hearing threshold at the best hearing frequency, not only at the middle frequencies.
