Human dermal fibroblast subpopulations and epithelial mesenchymal transition signals in hidradenitis suppurativa tunnels are normalized by spleen tyrosine kinase antagonism in vivo.

Hidradenitis Suppurativa is a chronic inflammatory disease of which the pathogenesis is incompletely understood. Dermal fibroblasts have been previously identified as a major source of inflammatory cytokines, however information pertaining to the characteristics of subpopulations of fibroblasts in HS remains unexplored. Using in silico-deconvolution of whole-tissue RNAseq, Nanostring gene expression panels and confirmatory immunohistochemistry we identified fibroblast subpopulations in HS tissue and their relationship to disease severity and lesion morphology.

Alterations to the Hidradenitis Suppurativa Serum Proteome with Spleen Tyrosine Kinase Antagonism: Proteomic Results from a Phase 2 Clinical Trial.

Hidradenitis suppurativa is a disease in great need of novel therapies. Given the heterogeneous nature of the disease and the variable response to therapies, biomarkers are essential to predict response to therapies and increase our understanding of disease pathogenesis. Our recent phase 2 clinical trial of spleen tyrosine kinase antagonism using fostamatinib in hidradenitis suppurativa demonstrated a 75% clinical response, with the greatest benefit in individuals with elevated serum inflammation and IgG.

A proof-of-concept open-label clinical trial of spleen tyrosine kinase antagonism using fostamatinib in moderate-to-severe hidradenitis suppurativa.

Background: Hidradenitis suppurativa (HS) is an autoinflammatory disorder of keratinization with a prominence of B cells and plasma cells. Fostamatinib is a spleen tyrosine kinase inhibitor targeting B cells and plasma cells.

Objectives: To assess the safety, tolerability, and clinical response at week 4 and week 12 of fostamatinib in moderate-to-severe HS.

Developing Remote Delivery of Language and Cognitive Training for Use With Children With Autism: A Technological Report.

Unlabelled: Remote delivery of language and cognitive training is becoming increasingly prevalent within special education settings, and the recent COVID-19 pandemic has challenged many providers to pivot to telehealth models. This technical article outlines a procedure for developing computerized discrete-trial training programs using commonly available software, as well as a description of how to adapt this strategy to teach chained tasks remotely. Within this article, we describe how to establish unidirectional and bidirectional remote interfaces to work directly with learners.

A novel approach to intrauterine viral inoculation of swine using PCV type 2 as a model.

Experimentally intrauterine (IU) viral inoculation has been commonly used to circumvent maternal interference with transplacental infection of fetuses and to assess the effect of viral infection on fetal development or reproductive parameters. However, IU inoculation requires surgical procedures such as laparatomy and surgical incision of the uterus. Post-surgical complications, that frequently result in abortion or fetal death, have been a major disadvantage.

Electrophoretic behavior and potency assessment of boar sperm using a capillary electrophoresis-laser induced fluorescence system.

The assessment of mammalian fertility, and the agents that affect it, is of increasing concern in medicinal, environmental, and agricultural science. The viability, integrity, and overall state of the male gamete (sperm) is an essential factor that must be considered in such studies. Traditional potency evaluations tend to be labor intensive and often are not precise.
