Vascular remodeling and TSLP/angiogenin overexpression in severe mixed asthma.

Background: Asthma with neutrophilic/mixed inflammation is a difficult-to-control clinical phenotype. Currently, vascular and matrix airway remodeling in asthma with neutrophilic/mixed inflammation is not well known. We aimed to evaluate the differences in vascular/smooth muscle/matrix related asthma remodeling in eosinophilic (EOS) and mixed/neutrophilic (MIXED) bronchial phenotypes in relation to asthma severity and exacerbation frequency.

Heterogeneous Earth's mantle drilled at an embryonic ocean.

Mantle processes control plate tectonics and exert an influence on biogeochemical cycles. However, the proportion of mantle sampled in-situ is minimal, as it is buried beneath igneous crust and sediments. Here we report the lithological characteristics of two mantle sections from an embryonic ocean drilled by the International Ocean Discovery Program (IODP) in the Tyrrhenian Sea.

Synthesis and Characterization of Memantine-Loaded Niosomes for Enhanced Alzheimer's Disease Targeting.

Over the past 25 years, numerous biological molecules, like recombinant lysosomal enzymes, neurotrophins, receptors, and therapeutic antibodies, have been tested in clinical trials for neurological diseases. However, achieving significant success in clinical applications has remained elusive. A primary challenge has been the inability of these molecules to traverse the blood-brain barrier (BBB).

Characterization and Proteomic Profiling of Hepatocyte-like Cells Derived from Human Wharton's Jelly Mesenchymal Stromal Cells: De Novo Expression of Liver-Specific Enzymes.

End-stage liver disease (ESLD), affecting millions worldwide, represents a challenging issue for clinical research and global public health. Liver transplantation is the gold standard therapeutic approach but shows some drawbacks. Hepatocyte transplantation could be a reliable alternative for patient treatment.

Honeybee toxicity of pesticides used in United States maize and soybean production, 1998-2020.

Pesticides are widely used around the world and have demonstrated benefits to crop production. However, pesticides have also been associated with negative impacts to nontarget organisms, including pollinators. Here, we combined pesticide usage and toxicity data to create a toxicity index, which shows that pesticide hazard to honeybees (Apis mellifera) has changed substantially in U.
