Protocol for high-resolution 3D spatial transcriptomics using Open-ST.

Spatial transcriptomics (ST) is fundamental for understanding molecular mechanisms in health and disease. Here, we present a protocol for efficient and high-resolution ST in 2D/3D with Open-ST. We describe all steps for repurposing Illumina flow cells into spatially barcoded capture areas and preparing ST libraries from stained cryosections.

Early hypoglycemia is not an independent risk factor for 2-year cognitive impairment in small for gestational age preterm infants of less than 32 weeks.

Unlabelled: The objective of this study is to evaluate whether early hypoglycemia is an independent risk factor for 2-year cognitive (COG) impairment in small for gestational age (SGA) preterm infants with gestational age (GA) < 32 weeks. We retrospectively reviewed data of 1364 preterm infants with a GA 24-31 weeks. Infants were classified based on blood glucose concentrations within the first 6 h of life (HOL) as < or ≥ 40 mg/dL (Glyc < 40 and Glyc ≥ 40, respectively) and subsequently by birth weight z-score as SGA or appropriate for gestational age (AGA).

SMURF1 and SMURF2 directly target GLI1 for ubiquitination and proteasome-dependent degradation.

The transcription factor GLI1 is the main and final effector of the Hedgehog signaling pathway, which is involved in embryonic development, cell proliferation and stemness. Whether activated through canonical or non-canonical mechanisms, GLI1 aberrant activity is associated with Hedgehog-dependent cancers, including medulloblastoma, as well as other tumoral contexts. Notwithstanding a growing body of evidence, which have highlighted the potential role of post translational modifications of GLI1, the complex mechanisms modulating GLI1 stability and activity have not been fully elucidated.

Exploring Genomic Biomarkers for Pembrolizumab Response: A Real-World Approach and Patient Similarity Network Analysis Reveal DNA Response and Repair Gene Mutations as a Signature.

: Single-agent immune checkpoint inhibitor (IO) therapy is the standard for non-oncogene-addicted advanced non-small cell lung cancer (aNSCLC) with PD-L1 tumor proportion score ≥ 50%. Smoking-induced harm generates high tumor mutation burden (H-TMB) in smoking patients (S-pts), while never-smoking patients (NS-pts) typically have low TMB (L-TMB) and are unresponsive to IO. However, the molecular characterization of NS-pts with H-TMB remains unclear.

Use of NSAIDs and acetaminophen and risk of spontaneous intestinal perforations in premature infants: a systematic review and meta-analysis.

Background: Acquired spontaneous intestinal perforation or SIP occurs most commonly in the extremely premature infant population. As the incidence is rising, understanding modifiable factors such as common medication exposures becomes important for individualizing care.

Methods: The primary outcome was SIP in premature infants with exposure to indomethacin, ibuprofen, or acetaminophen.
