BACKGROUND The true burden of reactivation of remote latent tuberculosis infection (reactivation TB) among foreign-born persons with tuberculosis (TB) within the United States is not known. Our study objectives were to estimate the proportion of foreign-born persons with TB due reactivation TB and to describe characteristics of foreign-born persons with reactivation TB. METHODS We conducted a...
We previously showed that the LAT function required for efficient spontaneous reactivation of herpes simplex virus type 1 (HSV-1) from neuronal latency in the rabbit maps within the first 1.5 kb of the 8.3-kb primary LAT transcript. This demonstrated that LAT does not function via an antisense mechanism, since the first 1.5 kb of LAT does not overlap any other known HSV-1 gene. Furthermore, if ...
It is believed that memory reactivation transiently renders consolidated memory labile and that this labile or deconsolidated memory is reconsolidated in a protein synthesis-dependent manner. The synaptic correlate of memory deconsolidation upon reactivation, however, has not been fully characterized. Here, we show that 3,5-dihydroxyphenylglycine (DHPG), an agonist for group I metabotropic glut...
Lack of p53 expression or expression of mutant p53 is common in human cancers and is associated with increased tumor growth and resistance to therapies. Significant efforts toward pharmaceutical reactivation of defective p53 by small molecules are therefore underway, targeting the different means that inactivate p53. Indeed, reactivated p53 can lead to tumor destruction. A recent paper in Cance...
Nasopharyngeal carcinoma (NPC) is a malignancy derived from the epithelial cells of the nasopharynx. Although a combination of radiotherapy with chemotherapy is effective for therapy, relapse and metastasis after remission remain major causes of mortality. Epstein-Barr virus (EBV) is believed to be one of causes of NPC development. We demonstrated previously that EBV reactivation is important f...
Remembering an event from the past is often complicated by the fact that our memories are cluttered with similar events. Though competition is a fundamental part of remembering, there is little evidence of how mnemonic competition is neurally represented. Here, we assessed whether competition between visual memories is captured in the relative degree to which target vs. competing memories are r...
Reactivation of diethyl p-nitrophenyl phosphate inhibited human serum cholinesterase by pyridine-Z-aldoxime methiodide and isonitrosoacetophenone has been investigated as a function of reactivator concentration, pH, and temperature in boric acid-borax buffer and in salt solution. Constants shown were the dissociation constants of the diethylphosphoryl cholinesterase reactivator complex for the ...
The ability to reinstate neuronal assemblies representing mnemonic information is thought to require their consolidation through offline reactivation during sleep/rest. To test this, we detected cell assembly patterns formed by repeated neuronal co-activations in the mouse hippocampus during exploration of spatial environments. We found that the reinstatement of assembly patterns representing a...
The administration of cortisone to chick embryos inoculated with large quantities of inactive influenza B virus results in a rate of viral increase greater than is concommittantly observed with inocula of comparable infectivity which are devoid of inactive particles. Thus, more than a mere negation of autointerference is effected. It is concluded that in the presence of cortisone reactivation h...
Three potential reactivators of nerve agents-inhibited acetylcholinesterase: 2-[(hydroxyimino)phenylmethyl]-1-methylpyridinium iodide 3a, 2-[(hydroxyimino)pyridin-2ylmethyl]-1-methylpyridinium iodide 3b and 2-[(1-hydroxyimino) ethyl]-1-methylpyridinium iodide 3c were synthesized. Their reactivation potency was examined using a standard in vitro reactivation test. A rat brain homogenate was used...
