Research on compression-rod lock–release mechanism with large load for space manipulator

With the development of Chinese space station, the space manipulator with large load plays a more and more important role. At the same time, the lock–release mechanism for the space manipulator must be reliable. In this study, the locking point layout method was proposed according to the size and the structure of the space manipulator, and the number and the position of the lock...

Preparation and evaluation of chitosan-calcium-gellan gum beads for controlled release of protein

The bead system composed of chitosan and calcium-gellan gum was prepared through a combination of ionotropic gelation and polyelectrolyte complexation for oral protein delivery. The characteristics of beads were investigated by scanning electron microscopy, Fourier transform infrared spectroscopy, differential scanning calorimetry, X-ray diffraction, release studies, and swelling...

Single-dose pharmacokinetic and toxicity analysis of pyrrole–imidazole polyamides in mice

PurposePyrrole–imidazole (Py-Im) polyamides are programmable, sequence-specific DNA minor groove–binding ligands. Previous work in cell culture has shown that various polyamides can be used to modulate the transcriptional programs of oncogenic transcription factors. In this study, two hairpin polyamides with demonstrated activity against androgen receptor signaling in cell...

1H and 13C NMR spectroscopic studies of the ferriheme resonances of three low-spin complexes of wild-type nitrophorin 2 and nitrophorin 2(V24E) as a function of pH

The ferriheme resonances of the low-spin (S = 1/2) complexes of wild-type (wt) nitrophorin 2 (NP2) and its heme pocket mutant NP2(V24E) with imidazole (ImH), histamine (Hm), and cyanide (CN−) as the sixth ligand have been investigated by NMR spectroscopy as a function of pH (4.0–7.5). For the three wt NP2 complexes, the ratio of the two possible heme orientational isomers, A and...
