ChemMedChem, Volume 21, Issue 9, 14 May 2026.The anticancer activity of the complexes Pd3Spd2, Pt3Spd2, Pt2Put2(NH3)4 and Pd2Put2 against human TNBC, non‐TNBC and healthy breast cells was evaluated. The metabolic impact of the most promising metal complexes—Pd3Spd2 and Pt2Put2(NH3)4—was further assessed using vibrational microspectroscopies, providing detailed insights into the drug‐induced ...

Acceleration of C iv and Si iv Broad Absorption Lines in Quasar SDSS J140058.79+260619.4
The Astronomical JournalWe report the discovery of a velocity shift signature in the C iv and Si iv broad absorption lines (BALs) of the quasar SDSS J140058.79+260619.4 ( z _em = 2.351). From its two-epoch spectra, we find two BAL systems (systems A and B) in C iv and/or Si iv

cDC1 Subtype‐Specific In Vivo Targeting of Liposomes
Advanced Science, Volume 13, Issue 19, 2 April 2026.Dendritic cells, particularly the cDC1 subtype, offer a promising target for drug delivery via liposomes due to their pivotal role in immune regulation, allowing for amplified therapeutic responses. Herein, we show an integration of physicochemical characterization and cell experiments to achieve effective in vivo cDC1 targeting through anti‐CLEC9A ...

Anisotropy Analysis of Bamboo and Tooth Using 4‐Angle Polarization Micro‐Spectroscopy
Nano Select, Volume 7, Issue 3, March 2026.Super‐resolution via orientation: spatial distribution of specific molecular vibrations are revealed at 1/20 of the diffraction limit. ABSTRACT To investigate the anisotropic properties of biomaterials, two distinct classes are considered as follows: polymer‐based (cellulose in plants) and crystalline‐based (enamel in teeth), each demonstrating ...
