Comparison of imaging-based single-cell resolution spatial transcriptomics profiling platforms using formalin-fixed, paraffin-embedded tumor samples.

Imaging-based spatial transcriptomics (ST) is evolving rapidly as a pivotal technology in studying the biology of tumors and their associated microenvironments. However, the strengths of the commercially available ST platforms in studying spatial biology have not been systematically evaluated using rigorously controlled experiments. In this study, we used serial 5-µm sections of formalin-fixed, paraffin-embedded surgically resected lung adenocarcinoma and pleural mesothelioma tumor samples in tissue microarrays to compare the performance of the single cell ST platforms CosMx, MERFISH, and Xenium (uni/multi-modal) platforms in reference to bulk RNA sequencing, multiplex immunofluorescence, GeoMx Digital Spatial Profiler, and hematoxylin and eosin staining data for the same samples.

Extent of genetic and epigenetic factor reprogramming via a single viral vector construct in deaf adult mice.

In the adult mammalian cochlea, hair cell loss is irreversible and causes deafness. The basic helix-loop transcription factor Atoh1 is essential for normal hair cell development in the embryonic ear. Over-expression of Atoh1 in the adult cochlea by gene therapy can convert supporting cells (cells that underlie hair cells) into a hair cell lineage.

Disparities of women's authorship in Colombia: A cross-sectional analysis.

Accepted manuscripts published in medical journals play a crucial role within the scientific community. Over the past few decades, there has been a gradual increase in the number of women entering the medical field. However, women remain underrepresented as first and last authors in medical journals.

First isolation of the Sindbis virus in mosquitoes from southwestern Spain reveals a new recent introduction from Africa.

Sindbis virus (SINV), is an of the family . This zoonotic arbovirus is transmitted by mosquitoes, primarily from the genus, with bird species acting as amplifying vertebrate hosts. Occasionally it can also affect humans that are accidental hosts.
