Summary: In this study, a series of novel nitrogen and oxygen-incorporated chromenonaphthophenanthridine-based elliptical dimers were synthesized through tandem Pictet-Spengler cyclization followed by ipso-aromatic substitution in one-pot. Their mesophase characteristics were characterized by optical microscopy, differential scanning calorimetry, and X-ray diffraction studies. The photophysical properties were investigated using UV-vis and emission spectroscopy, and the charge transport properties were analyzed by time-of-flight measurements, with observed ambipolar mobilities of the order of 10(-3) cm(2) V-1 s(-1). These materials show promising potential for applications in organic electronics due to their high solubility, excellent thermal stability, self-organizing properties, and ambipolar charge transport characteristics.

Summary: In this study, a metal-free phthalocyanine-based discotic liquid crystal (PcDLC) was tested for its corrosion inhibitory capacity on mild steel (MS) samples in 1.0 M HCl medium using potentiodynamic and electrochemical impedance parameters. The PcDLC exhibited excellent corrosion inhibition with a maximum efficiency of 89.61%. The strong adsorption of PcDLC onto the MS surface was responsible for this superior ability. Scanning electron microscopy and FTIR confirmed the formation of a protective layer of inhibitors on the MS surface. Density function theory revealed a strong interaction between the inhibitor and surface iron atoms.

Summary: Emerging evidence suggests that microRNA-141-3p plays a role in age-related pathologies. In this study, we inhibited miR-141-3p expression in aged mice and observed improved immune, bone, and muscle health. Treatment with Anti-miR-141-3p resulted in decreased pro-inflammatory cytokines, a shift from pro-inflammatory to anti-inflammatory immune cell populations, and improved bone microstructure and muscle fiber size. Molecular analysis revealed the role of miR-141-3p in regulating senescence and inflammation, as well as its potential crosstalk with FOXO-1 transcription factor. These findings suggest that inhibiting miR-141-3p may be a potential strategy for promoting healthy aging.
