Background: The aim of this study was to develop methods for cryopreservation and long-term maintenance of putative bovine embryonic stem cells (ESCs). Materials and Methods: Putative bovine ESC (bESC) lines (n=3) isolated in conventional medium were used to compare slow-freezing and vitrification. Results: After warming, vitrified cells (96.9%) demonstrated significantly (p<0.05) better surviv...

Little is known of the normal physiological processes that govern the cell surface residency of the human follitropin receptor (hFSHR), a G protein-coupled receptor expressed in the ovary and testis. In the hFSHR, the third intracellular (3i) loop is considered to be pivotal in attenuation of ligand activation, particularly internalization. To gain a better understanding of these processes, we ...

This work describes an integrated approach of de novo drug design, chemical synthesis, and bioassay for quick identification of a series of novel small molecule cyclophilin A (CypA) inhibitors (1-3). The activities of the two most potent CypA inhibitors (3h and 3i) are 2.59 and 1.52 nM, respectively, which are about 16 and 27 times more potent than that of cyclosporin A. This study clearly demo...

Adv. Mater. 2019, 31, 1900843 The authors realized there was a mistake in Figure 3i the originally published article, which arose preparation of figure. After correction, new is shown as below. With description figure should also be modified. To specific, sentence on page 5 7 “For OER, rate-limiting steps for both co-doped graphene and N single-doped correspond to formation O* species (Figure 3...

This paper describes a novel online tool, Individualized, Interactive Instruction (3i), that enables new instructional approaches based on formative assessment. The 3i system provides real-time feedback from students to instructors in the classroom. 3i directly displays each student’s progress on specific problem solving tasks that reveal understanding of instructional topics. The 3i system des...

The synthesis of a novel dihydropyridine derivatives bearing dimedone as an excellent precursor has been achieved by applying three component Hantzsch condensation. The newly synthesized compounds were characterized by IR, NMR, Mass spectra and also by C, H, N analyses. All synthesized compounds undergo docking studies and biological screening for antimicrobial activity against Gram-positive ba...

Synthesis and biological evaluation of unsymmetrical curcumin analogues (UCAs) have been achieved. Tyrosinase inhibitory activities were found for most of the prepared synthetic UCAs. Among them, compounds containing 4-hydroxyl-substituted phenolic rings with C-2/C-4- or C-3/C-4-dihydroxyl-substituted diphenolic rings were more active (IC(50) = 1.74~16.74 μM) than 4-butylresorcinol and kojic ac...
