We report the case of a 46-year-old man who tolerated 50 mg per day of cetirizine for the treatment of chronic idiopathic urticaria. The patient denied any sedation or somnolence and had no difficulty performing routine daily functions including driving. He had tried other antihistamines, including fexofenadine, loratadine, and hydroxyzine without improvement.

The main goal of the current study is to estimate the in vivo anti-inflammatory/antioxidant ability of four selected pharmaceutical compounds: bisoprolol (Biso), piracetam (Pirc), clopidogrel (Clop), and cinnarizine (Cinna). Indomethacin (Indo) was used as a reference drug to perform a realistic comparison between the four compounds and the Indo in vivo through tracking PI3K/AKT signaling and computational chemistry via density functional theory (DFT) modeling to analyze the electrostatic potential across the molecule and provide insight into the regions for receptor binding of the studied compounds. To achieve the safe dose of these compounds, cytotoxicity was performed against isolated adipose tissue-derived mesenchymal stem cells (ADMSCs) using MTT assay.

However, current plasma and CSF sampling methods to estimate brain tissue exposure of ASOs are inherently limited, hampering ASO clinical developmental plans. We developed the PET tracer [F]BIO-687, which binds ASO conjugates (ASO-Tz) in vivo, allowing us to image ASO distribution in a living brain using "pretargeted" imaging.

RSW was considered a rare to nonexistent syndrome until we found 24 (38%) of 62 hyponatremic patients in a general medical ward to have RSW. We induced RSW in rats by injecting plasma from 18 AD patients suspected to have RSW.

Background: Growing evidence indicates that people with neurodegenerative diseases have altered metabolic status, but the association between metabolic age (MetAge), as assessed by circulating plasma metabolomics, and dementia remains unclear. We aimed to investigate the association between MetAge and risk of dementia and to explore whether genetic background plays a role in these associations.
Method: From the UK Biobank, 153,436 dementia-free adults aged ≥55 (mean age 62.
