Targeted Conversion from Mitochondria to the Nucleus of Hydroxystyrylpyridinium by Introducing Only an Additional -Hydroxyl Group.

Aromatic cationic groups serve as crucial building blocks for the design of fluorescent probes targeting both the nucleus and mitochondria. Therefore, it is a significant challenge to develop aromatic cation-based probes that accurately image the nucleus without interference from mitochondria. However, this also presents an opportunity for rational design by modifying probes originally targeting mitochondria to redirect their targeting toward the nucleus.

Clinical characteristics and risk factors of infection in initially treated patients with multiple myeloma during the induction period.

Background: Multiple myeloma (MM) is a common hematologic malignancy and immune dysfunction is a hallmark of the disease. It leads to an increased infection risk, which is still a major cause of mortality. The infection spectrum and characteristics have evolved with the introduction of novel agents.

Microglial depletion rescues spatial memory impairment caused by LPS administration in adult mice.

Recent studies have highlighted the importance of microglia, the resident macrophages in the brain, in regulating cognitive functions such as learning and memory in both healthy and diseased states. However, there are conflicting results and the underlying mechanisms are not fully understood. In this study, we examined the effect of depleting adult microglia on spatial learning and memory under both physiological conditions and lipopolysaccharide (LPS)-induced neuroinflammation.

Two-Photon Cellular and Intravital Imaging of Hypochlorous Acid by Fluorescent Probes That Exhibit a Synergistic Excited-State Intramolecular Proton Transfer-Intramolecular Charge Transfer Mechanism Enabling Near-Infrared Emission with a Large Stokes Shift.

To develop highly effective molecular tools for intravital imaging of hypochlorous acid (HOCl), in this study, we initially designed two-photon hybrid fluorophores, and , by conjugating the classical dye 2-(2'-hydroxyphenyl)benzothiazole with the two-photon hydroxylphenyl-butadienylpyridinium fluorophore. The designed fluorophores exhibit a synergistic interaction between excited-state intramolecular proton transfer and intramolecular charge transfer mechanisms, enabling near-infrared (NIR) emission and significant Stokes shifts. Subsequently, using these fluorophores, we developed two HOCl fluorescent probes, and , by further incorporating ,-dimethylthiocarbamate as a specific recognition group for HOCl.

Analysis of the Haematological Phenotype and Molecular Characteristics of Rare Abnormal Haemoglobin.
