Horizontal transmission of Streptococcus pneumoniae in the surgical ward: a rare source of nosocomial wound infection.
Am J Infect Control

Hide Abstract
Streptococcus pneumoniae is rarely isolated from nosocomial infections. We report an outbreak of 4 nosocomial-acquired surgical site infections due to S pneumoniae after retropubic simple prostatectomy. The likely source was detected in the rhinopharynx of the surgeon. After the implementation of recommendations, no new cases have been recorded.

Clinical significance and prognostic value of chromatin assembly factor-1 overexpression in human solid tumours.
Histopathology

Hide Abstract
Chromatin assembly factor-1 (CAF-1), whose function is critical for maintaining chromatin stability during DNA replication and repair, has been identified as a proliferation marker in breast cancer. The aim was to investigate CAF-1 as a proliferation marker in a wide variety of solid tumours, and to assess its potential value in predicting clinical outcome.

Gene coexpression analysis in single cells indicates lymphomyeloid copriming in short-term hematopoietic stem cells and multipotent progenitors.

Hide Abstract
Progressive restriction to a differentiation pathway results from both activation and silencing of particular gene expression programs. To identify the coexpression and the expression levels of regulatory genes during hematopoietic stem cell (HSC) differentiation toward the T cell branch, we applied a new single-cell RT-PCR technique to analyze the simultaneous expression of 13 genes in 9 functionally purified populations from the bone marrow and the thymus. We report in this paper that Lin(-)Sca1(+)ckit(+) HSCs display, at the single-cell level, a homogeneous and high transcriptional activity as do early thymic progenitors. Moreover, the coexpression of lymphoid and myeloid genes is an early event detected in approximately 30% of short-term HSC and most multipotent progenitors, suggesting novel sources for the generation of early thymic progenitors, common lymphoid progenitors (CLPs), and common myeloid progenitors. Loss of multipotency in Lin(-)Sca1(+)ckit(+) cells directed to the lymphoid branch is characterized by Lmo2 and Gata2 gene expression downregulation. Indeed, highest levels of Gata2 expression are detected only in long-term and short-term HSC populations. Complete shutdown of Pu1 gene expression in all triple-negative (TN)3 stage thymic pre-T cells is indicative of total T cell commitment. Interestingly, this is also observed in 30% of TN2 cells and 25% of CLP in the bone marrow, suggesting a possible initiation of T cell engagement in TN2 and CLP. Also, our strategy highlights similar gene patterns among HSCs and intrathymic progenitors, proposing, therefore, that identical activation signals are maintained until further maturation and generation of CD4 and CD8 coreceptors bearing thymocytes.

This retrospective analysis was designed to confirm the predictive role of urokinase-type plasminogen activator (uPA) and plasminogen activator inhibitor type I (PAI-1) in the outcome of early stage, node-negative breast cancer patients.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
