Image-based spatial transcriptomics platforms are powerful tools often used to identify cell populations and describe gene expression in intact tissue. Spatial experiments return large, high-dimension datasets and several open-source software packages are available to facilitate analysis and visualization. Spatial results are typically imperfect.

Background/objectives: Studies have shown that consistent reductions of 2 mm Hg in systolic blood pressure (SBP) for the general normotensive population can result in significant decreases in mortality from heart disease and stroke. The purpose of this meta-analysis was to determine the optimal dose and duration of treatment for magnesium and potassium supplementation, having previously discovered that both reduce SBP by -2.79 and -2.

We present an enhancer AAV toolbox for accessing and perturbing striatal cell types and circuits. Best-in-class vectors were curated for accessing major striatal neuron populations including medium spiny neurons (MSNs), direct and indirect pathway MSNs, as well as Sst-Chodl, Pvalb-Pthlh, and cholinergic interneurons. Specificity was evaluated by multiple modes of molecular validation, three different routes of virus delivery, and with diverse transgene cargos.

Article Synopsis
  • Advanced pancreatic ductal adenocarcinoma (PDAC) has different subtypes, with the basal-like subtype showing worse prognosis and chemotherapy resistance compared to the classical subtype.
  • This study evaluated immunohistochemistry (IHC) staining of four markers on biopsy samples from 190 untreated advanced PDAC patients, identifying three distinct patterns: Classical, Transitional, and Basal-like.
  • The Basal-like pattern was linked to poorer survival rates and associated with specific histological features, making IHC expression patterns a valuable tool for predicting prognosis and guiding treatment decisions in advanced PDAC.

Background: Hidradenitis suppurativa (HS) is a chronic inflammatory condition of the skin that mainly affects the apocrine gland-rich intertriginous areas. The disease manifests as painful nodules, abscesses, and pus-filled tunnels, which can severely impact patient's quality of life. While diagnosis is clinical, successful treatment options for this condition are limited.
