Real-time heart rate monitoring system for cardiotoxicity assessment of Daphnia magna using high-speed digital holographic microscopy.
Kwon IH, Kim IY, Heo MB, Park JW, Lee SW, Lee TG. Kwon IH, et al. Sci Total Environ. 2021 Aug 1;780:146405. doi: 10.1016/j.scitotenv.2021.146405. Epub 2021 Mar 17. Sci Total Environ. 2021. PMID: 33774290 Free article.
However, the requisite large data sizes and long calculation times make long-term observations of heart rates difficult. In this study, we developed a real-time heart rate monitoring system for individual Daphnia magna in a water chamber mounter that immobilizes their move …

Neuregulin-1 impairs the long-term depression of hippocampal inhibitory synapses by facilitating the degradation of endocannabinoid 2-AG.
Du H, Kwon IK, Kim J. Du H, et al. Among authors: kwon ik. J Neurosci. 2013 Sep 18;33(38):15022-31. doi: 10.1523/JNEUROSCI.5833-12.2013. J Neurosci. 2013. PMID: 24048832 Free PMC article.
As a result, the time course of depolarization-induced 2-AG signaling was shortened, and the magnitude of 2-AG-dependent long-term depression of inhibitory synapses was reduced. Our study reveals that an alteration in the signaling of 2-AG contributes to hippocampal synapt …

Osteoblastic and osteoclastic differentiation on SLA and hydrophilic modified SLA titanium surfaces.
Bang SM, Moon HJ, Kwon YD, Yoo JY, Pae A, Kwon IK. Bang SM, et al. Among authors: kwon ik. Clin Oral Implants Res. 2014 Jul;25(7):831-7. doi: 10.1111/clr.12146. Epub 2013 Apr 8. Clin Oral Implants Res. 2014. PMID: 23560589
CONCLUSION: It may be concluded that the modSLA surface promotes osteogenic effect and prevents osteoclastic differentiation. Promotion of osteoblastic proliferation after a short-term cell culture might be responsible for stimulated bone regeneration implying that early l …

These results suggested that berberine aggravated 6-OHDA-induced cytotoxicity in PC12 cells, and led to the degeneration of dopaminergic neuronal cells in the substantia nigra of 6-OHDA-lesioned rats. It is, therefore, suggested that the use of long-term l-DOPA therapy wit …
