It has been suggested that the human immune modulation gene down regulates the response to a sustained viral presence, and that disabling this gene may reactivate aggressive immune reactivity that could control the progression to AIDS.
We speculate that CMV remains latent in the anterior chamber in some individuals, and this may reactivate when the local milieu is altered, such as with the administration of prostaglandin analogues.
Interestingly, data are beginning to accumulate supporting the notion that viruses may reactivate in immunocompetent patients during times of critical illness, and this reactivation seems to be associated with worse clinical outcomes, including mortality [ 6, 7].
Decades later, it may reactivate along the nerve pathway and cause the very painful rash called shingles, and later, in many cases, a persistent pain called postherpetic neuralgia, or PHN.
According to this concept, the DA agonist given first may reactivate this memory circuit, thereby rendering it transiently labile.
"By going deeper we may reactivate the possibility that smallpox could become again a disease of humans in modern times".
During CO2 injection into the formation, stress changes may reactivate the natural fractures providing path for CO2 to migrate into the matrix displacing oil toward the well perforations.
Vertebral augmentation may reactivate a quiescent tuberculous lesion and promote the infective process in elderly patients with or without immunosuppression, thereby resulting in poor outcomes.
Depending on the bone defect's size and the surrounding soft tissue, it may be necessary to integrate the plastic in multiple steps in order to avoid cancellous bone graft necrosis, which may reactivate the osteitis (Figs. 5, 6, 7).
This process repeats again if no more jobs are available in the system, i.e. the server may reactivate at the end of lth (1 ≤ l ≤ J) vacation if any customer/job is available in the system.
