AI Article Synopsis
Article Abstract
To discover drug candidates with anti-angiogenesis activity for cancer therapeutics, three galactooligosaccharides (OJ1-OJ3) were prepared by acid hydrolysis of the polysaccharides from Nerium indicum Mill. Their structures were characterized using sugar analysis, methylation analysis, and both 1D and 2D NMR spectroscopy, complemented by mass spectrometry. They were hexasaccharide (OJ1), a pentasaccharide (OJ2), and an undecasaccharide (OJ3), which was a new linear galactan. Bioactivity testing in vitro showed that OJ2 and OJ3 significantly inhibited the HMEC-1 (human microvascular endothelial cell) cell tube formation.

Spin labels based on Gd complexes are important tools for the elucidation of the structure, dynamics and interaction of biomolecules by electron paramagnetic resonance (EPR) spectroscopy. Their EPR spectroscopic properties line width and relaxation times influence their performance in a particular application. To be able to apply a complex well-suited for a specific application, a set of Gd complexes with different EPR spectroscopic properties ready-made for spin labeling will be highly useful.

Aim: Snakes exhibit remarkable physiological shifts when their large meals induce robust postprandial growth after prolonged fasting. To understand the regulatory mechanisms underlying this rapid metabolic transition, we examined the regulation of protein synthesis in pythons, focusing on processes driving early postprandial tissue remodeling and growth.
Methods: Using the SUnSET method with puromycin labeling, we measured in vivo protein synthesis in fasting and digesting snakes at multiple post-feeding intervals.

Rationale: Teaching mass spectrometry essentials is usually connected with one of the basic courses for undergrads. Thus, specific previous knowledge is required from students. However, the necessity of teaching mass spectrometry essentials to students of different academic specializations and multidisciplinary groups can arise in every academic group.
