In situ hybridization (ISH) for identification of infectious replicative cytomegalovirus (CMV) in cell culture microplates (96 microwells) infected by clinical specimens was tested by using a biotin-labeled DNA probe and an avidin-alkaline phosphatase conjugate. A total of 395 specimens were examined by using ISH and a monoclonal antibody (MAb) specific for an early antigen of CMV. Of 47 specimens that gave a positive signal for CMV by ISH, 33 were confirmed virus positive by MAb staining. Of 141 blood samples tested, 4.96% were positive by ISH, and 0.7% were positive by the MAb technique. ISH shows 40% more sensitivity than MAb staining. This technique should be widely applicable for the specific identification of viral isolates (e.g., herpesvirus, myxovirus, paramyxovirus, and enterovirus) in cell culture 96-microwell microplates, thereby making it feasible to screen a larger number of samples than is possible with classical methods using conventional culture tubes, shell vials, or 24-well plates.

The safety of a 2'--methoxyethyl antisense oligonucleotide (ASO) was investigated in Mauritius cynomolgus monkeys in a 41-week Good Laboratory Practice (GLP) toxicity study after multiple intrathecal (IT) administrations. Histopathological examination revealed ectopic formation of lymphoid follicles in the spinal cord (SC) at the injection site at all doses and the presence of granular material in neurons of the SC in high-dose animals. The granular material was seen in all the segments of the SC, but mainly in the lumbar segment and persisted at the end of the 26-week recovery period, while the lymphoid follicles showed a reversibility trend.

Background: Closed head injury (CHI) provokes a prominent neuroinflammation that may lead to long-term health consequences. Microglia plays pivotal and complex roles in neuroinflammation-mediated neuronal insult and repair following CHI. We previously reported that induced neural stem cells (iNSCs) can block the effects of CXCL12/CXCR4 signaling on NF-κB activation in activated microglia by CXCR4 overexpression.

Background: Inflammatory myofibroblastic tumors (IMTs), rare soft tissue neoplasms, are characterized by a blend of myofibroblastic proliferation and inflammatory features. While generally characterized by slow growth, IMTs can exhibit locally aggressive behavior, and in rare instances, metastasize to distant sites. This study elucidated the clinical characteristics, molecular profile, and tumor microenvironment of thoracic IMTs.

(2n=2x=14, genome SS) is a wild relative of wheat and a donor of useful traits for wheat improvement. Several whole-genome studies compared genic regions of from the section and wheat and found that is most closely related to the wheat B subgenome but is not its direct progenitor. The results showed that a B subgenome ancestor diverged from more than 4 MYA and either has not yet been discovered, or is extinct.
