Article Abstract
We investigate experimentally and numerically the stochastic dynamics and the time-dependent response of colloids subject to a small external perturbation in a dense bath of motile E. coli bacteria. The external field is a magnetic field acting on a superparamagnetic microbead suspended in an active medium. The measured linear response reveals an instantaneous friction kernel despite the complexity of the bacterial bath. By comparing the mean squared displacement and the response function we detect a clear violation of the fluctuation dissipation theorem.

Background: Stroke-prone spontaneously hypertensive rats (SHRSP) exhibit slow-twitch muscle-specific hypotrophy compared with normotensive Wistar-Kyoto rats (WKY). Because slow-twitch muscles are prone to disuse atrophy, SHRSP may experience both disuse atrophy and impaired recovery from it. This study investigated the response of SHRSP to disuse atrophy and subsequent recovery, using WKY as a control.

Five new heterodimers, chalasoergodimers A-E (1-5), and three known heterodimers (6-8), along with four chaetoglobosin monomers (9-12), were isolated from a marine-derived Chaetomium sp. fungus. The structures of new compounds 1-5 were elucidated by HRESIMS, NMR, chemical calculated C NMR and ECD methods.

The development of analytical techniques applicable to powdered pharmaceutical co-crystals, including those containing excipients, represents a comprehensive strategy for quality control in both drug development and regulatory settings. This study investigates the structural characterization of indomethacin-nicotinamide co-crystals using a combination of microcrystal electron diffraction (microED), solid-state NMR (SSNMR), Raman spectroscopy, and powder X-ray diffraction (PXRD). MicroED analysis revealed the crystal structure of the co-crystal, while SSNMR measurements provided insights into the molecular interactions within the structure.

Liver cancer is the fourth most deadly cancer worldwide, but existing treatment options are insufficient, thus highlighting the urgent need for new therapeutic agents. Taxanes, known for their anticancer properties, provide a promising avenue for intervention. In this study, a tetracyclic taxane compound with antitumor activity (taxinine) was extracted and isolated from Taxus chinensis (T.

3D scaffold architecture is critical for directing human neural stem cell (hNSC) fate and spatial organization. In this study, two-photon lithography (TPL) is used to fabricate microcapillary scaffolds based on the Hilbert space-filling curve as biomimetic basement membrane structures for guiding hippocampal-derived hNSC differentiation. The scaffolds feature 80 µm lumens with porous ellipsoidal membranes suspended above the substrate to provide topographical cues and permit nutrient diffusion while maintaining mechanical stability.
