  • The combination of cobalt ferrite and natural rubber has a potential to enhance the functional properties of rubber ferrite composites available on the market. In this study, cobalt ferrite was synthesized by the sol-gel method with tapioca starch as a cheating agent and then incorporated into natural rubber using an internal mixer. The curing characteristics, magnetic hysteresis, complex permeability, and permittivity of the rubber ferrite composites were studied as a function of the loading from 0 to 25 phr. The cure time and scorch time tended to reduce with the addition of non-reinforced cobalt ferrite fillers. The remanent and saturation magnetizations were linearly proportional to the cobalt ferrite loading, consistent with the rule of mixture. On the other hand, the increase in cobalt ferrite loading from 5 to 25 phr slightly affected the coercive field and the complex permeability. Using the maximum loading of 25 phr, both real and imaginary parts of the permittivity were significantly raised and reduced with the frequency in the 10-300 MHz range.

  • Aminoacyl-tRNA synthetases (aaRSs) play vital roles in protein biosynthesis of living organisms and are interesting antibacterial drug targets. In order to find out new inhibitor candidate molecules as antibacterial agent, the binding modes of the candidate molecules were investigated at the active sites of aaRSs by molecular docking study. The docking simulations were performed with 48 compounds from four different scaffolds into the eight different aaRSs. The results show that scaffolds 3 and 4 compounds have consistently better binding capabilities, specifically for HisRS (E. coli) and IleRS (S. aureus). The binding modes of the best compounds with the proteins were well compatible with those of two ligands in crystal structures. Therefore, we expect that the final compounds we present may have reasonable aaRS inhibitory activity.

  • The regulation for the low and intermediate level radioactive waste to be transferred to the disposal facility, recently revised, require that radioactive waste generators should set up waste certification program to verify the radioactive waste conform to the waste acceptance criteria(WAC) before disposal. The radioactive waste disposal facility, scheduled to be constructed in Korea, will institute WAC for the wastes to be transferred to the facility. This WAC is expected to compose of the requirements for the radiological characterization, physical and chemical characterization, physical/chemical restriction, prohibited item, packaging, identification, labeling, and documentation. For the compliance with this regulation, The radioactive waste generators should verify that the waste meet WAC through performance of the waste certification program and are responsible for handing in all the certification documents to the disposal facility. This waste certification program plan was set up as a preliminary program for the certification of radioactive waste generated in Korea Atomic Energy Research Institute (KAERI) and should be further revised until preparation of WAC by disposal agent.

  • In this study, we carried out a series of experiments to know whether melatonin, an anti-oxidative and immunosuppressive agent, played an important role in endothelial cells. It was revealed that melatonin had little or no effect on endothelial proliferation, cell death or migration. Additionally, melatonin had no effect on adhesion of THP-1 leukocytes to bovine aortic endothelial cells (BAECs) and THP-1 homotypic cell aggregation. In contrast, it was shown that melatonin diminished the basal level of nitric oxide by PP2A-mediated dephosphorylation of endothelial nitric oxide synthase (eNOS), leading to enhanced detachment of BAEC from the extracellular matrix. Collectively, melatonin in high doses decreases the NO production via regulations of PP2A and eNOS activities, inducing detachment of endothelial cells, a possible initial step for thrombosis.

  • Little is known about the cardiovascular effects of Lycopene, an anti-cancer and anti-oxidative agent. In this study, we executed a series of experiments with vascular endothelial cells to disclose the cardiovascular functions of lycopene. From our in vitro experiments, lycopene was determined to act as a stimulant to induce endothelial cell proliferation and migration. In addition, lycopene was shown to inhibit lipopolysaccharide (LPS)-induced adhesion of THP-1 leukocytes to endothelial cells, as well as activating mitogen activated protein kinase (MAPK) family members, ERK, JNK and p38 MAPK. Both ERK and p38 MAPK were involved in lycopene-induced cell proliferation, while JNK was involved in lycopene-dependent cell migration. Taken together, lycopene activates MAPK family members which regulate cell proliferation and migration. Lycopene differentially blocks LPS-dependent adhesion for THP-1 to endothelial cells, indicating that lycopene is likely to regulate a variety of vascular functions.

  • Reproductive incompatibility is an Important factor to select a specific biologlcal control agent for successful augmentation of the corresponding endogenous population. An endoparasitoid, Cotesia plutellae (Kurdjumov), is an effective control agent to diamondback moth, Plutella xylostella (L.) and has been known to be classified into two groups in terms of reproductive incompatibility. This study analyzed an Korean population of C. plutellae in terms of morphological characters and mitochondrial DNA marker, which did not match with either of two reproductive incompatibility groups. These results suggest that a Korean population of C. plutellae can be involved in a novel reproductive group. For any augmentation program of C. plutellae in Korea, reproductive incompatibility should be seriously considered to select a particular exotic population.
