A clone of human cells (Detroit 6) latently infected by adeno-associated virus (AAV) has been characterized with regard to the status viral DNA. In both early (9 10) and late (118) passages clone, AAV-DNA was recombined host DNA, at least in some cases as a head-to-tail tandem repeat, via terminal sequences genome. However, it not possible distinguish between integration into chromosomal DNA very large plasmids (< 20 x 10(6) molecular weight) which contain cellular sequences. Although...

Inborn errors of human IFN-γ-dependent macrophagic immunity underlie mycobacterial diseases, whereas inborn IFN-α/β-dependent intrinsic viral diseases. Both types IFNs induce the transcription factor IRF1. We describe unrelated children with inherited complete IRF1 deficiency and early-onset, multiple, life-threatening diseases caused by weakly virulent mycobacteria related intramacrophagic pathogens. These have no history severe disease, despite exposure to many viruses, including...

Importance Whether endovascular thrombectomy (EVT) efficacy for patients with acute ischemic stroke and large cores varies depending on the extent of injury is uncertain. Objective To describe relationship between imaging estimates irreversibly injured brain (core) at-risk regions (mismatch) clinical outcomes EVT treatment effect.

Although previous trials have established the efficacy and safety of endovascular thrombectomy (EVT) in large ischemic core strokes, most them excluded patients with extracranial internal carotid artery (e-ICA) occlusion. We aimed to compare outcomes e-ICA occlusion infarcts treated EVT vs medical management (MM). This was a secondary analysis SELECT2 trial, randomized controlled trial conducted at 31 international sites. Adult proximal intracranial anterior circulation defined as Alberta...

Background The Pipeline Embolisation Device with Shield technology (PED-Shield) is suggested to have reduced thrombogenicity. This thrombogenicity may make it possible use safely in the acute treatment of aneurysmal subarachnoid haemorrhage (aSAH) on single antiplatelet therapy (SAPT). Objective To evaluate safety and efficacy off-label PED-Shield SAPT for aSAH. Methods Patients who underwent ruptured intracranial aneurysms were retrospectively identified from prospectively maintained...

At least three separate regions of the Epstein-Barr virus (EBV) genome encode RNA in a cell line that is growth transformed and nonpermissively infected with EBV. Six polyadenylylated cytoplasmic RNAs have been identified from these regions. An abundant 3.0-3.1 kilobases (kb) long encoded by DNA internal reiteration, IR, maps at 25.7-30 megadaltons. A second, abundant, 2.9-kb primarily 110-03 megadaltons but probably has 3' end to left 110 third, 3.7-kb largely 63-66 5' 63 less-abundant...

Two pseudorabies virus (PRV) poly(A)+ RNAs, 2.0 and 0.95 kilobases, were detected in the trigeminal ganglia of latently infected pigs. These RNAs partially colinear at 3' end. They located BamHI J fragment (0.706 to 0.737 map units), PRV immediate-early gene. A potential polyadenylation signal was also identified BamHI-J. The direction transcription latency-associated antiparallel (i.e., opposite polarity) that mRNA.
