Intrusive memories are unwanted recollections that maintain distress in psychological disorders. Increasing evidence suggests that memories that are reactivated through retrieval become temporarily vulnerable to environmental or pharmacological manipulation, including changes in levels of circulating stress hormones. This study investigated the influence of stress during memory reactivation of ...

We developed a simple, fast, economical, and versatile reactivation method for the study of herpes simplex virus type 1 (HSV-1) latency in the rabbit ocular model. Intrastromal injection of sterile, deionized water induced reactivation and ocular shedding of latent HSV-1 in 21 of 27 eyes (78%) in 93% of New Zealand rabbits. Other control groups (eg, anterior chamber injection of sterile, deioni...

Hepatitis B virus (HBV) reactivation has previously occurred in hepatitis B surface antigen-negative patients with malignant lymphoma who received rituximab-based combination chemotherapy. However, few reports have described cases of HBV reactivation in patients with multiple myeloma thus far. We report a case of HBV reactivation in a patient with multiple myeloma treated with chemotherapy, aut...

The presentation of a fear memory cue can result in mere memory retrieval, destabilization of the reactivated memory trace, or the formation of an extinction memory. The interaction between the degree of novelty during reactivation and previous learning conditions is thought to determine the outcome of a reactivation session. This study aimed to evaluate whether contextual novelty can prevent c...

We have developed a screening platform for the isolation of genetic entities involved in metastatic reactivation. Retroviral libraries of cDNAs from fully metastatic breast-cancer cells or pooled microRNAs were transduced into breast-cancer cells that become dormant upon infiltrating the lung. Upon inoculation in the tail vein of mice, the cells that had acquired the ability to undergo reactiva...

Self-rated health (SRH) is a reliable predictor of health outcomes including morbidity and mortality. Immune dysregulation is one hypothesized mechanism underlying the association between SRH and health outcomes. Indeed, poorer SRH is associated with greater inflammation. The association between SRH and reactivation of latent herpesviruses is unknown, representing an important gap in the litera...

The hippocampus has the capacity for reactivating recently acquired memories and it is hypothesized that one of the functions of sleep reactivation is the facilitation of consolidation of novel memory traces. The dynamic and network processes underlying such a reactivation remain, however, unknown. We show that such a reactivation characterized by local, self-sustained activity of a network reg...

Latent herpes simplex virus-1 (HSV1) genomes in peripheral nerve ganglia periodically reactivate, initiating a gene expression program required for productive replication. Whether molecular cues detected by axons can be relayed to cell bodies and harnessed to regulate latent genome expression in neuronal nuclei is unknown. Using a neuron culture model, we found that inhibiting mTOR, depleting i...

this report presents a 3.5-year-old boy who was hospitalized for limping. medical history and physical exams were not suggestive for any definitive diagnosis. laboratory and radiographic exams did not support any specific diagnosis either. subsequently bone scan was performed and increased activity in the ankle due to cuboid fracture was incidentally observed.

The mechanical integrity of caprocks overlying injection formations is one the key factors for safe storage carbon dioxide in geological formations. Undrained effects caused by CO2 on strength and elastic parameters should be properly considered operational design to avoid fracture creation, fault reactivation unwanted surface uplift. This study presents results from eleven undrained triaxial c...
