Microporous, non-woven poly( epsilon -caprolactone) (PCL) scaffolds were made by electrostatic fiber spinning. In this process, polymer fibers with diameters down to the nanometer range, or nanofibers, are formed by subjecting a fluid jet to a high electric field. Mesenchymal stem cells (MSCs) derived from the bone marrow of neonatal rats were cultured,(More)
The circumsporozoite protein (CSP) of Plasmodium vivax has two sequence types, VK210 and VK247, each of which has a characteristic tandem amino acid repetition. Previous studies report that a resurgent Korean strain has unique amino acid sequences in tandem repeats and post-repeat areas compared to other strains of P. vivax. We have found another molecular(More)
We introduce a new concept of ‘co-recognition’ for object-level image matching between an arbitrary image pair. Our method augments putative local regionmatches to reliable object-level correspondenceswithout any supervision or prior knowledge on common objects. It provides the number of reliable common objects and the dense correspondences between the(More)
We address an unsupervised object detection and segmentation problem that goes beyond the conventional assumptions of one-to-one object correspondences or modeltest settings between images. Our method can detect and segment identical objects directly from a single image or a handful of images without any supervision. To detect and segment all the(More)
AIMS Cardiac tissue engineering has been proposed as an appropriate method to repair myocardial infarction (MI). Evidence suggests that a cell with scaffold combination was more effective than a cell-only implant. Nevertheless, to date, there has been no research into elastic biodegradable poly(lactide-co-epsilon-caprolactone) (PLCL) scaffolds. The aim of(More)
Endophytic actinobacterial diversity in the native herbaceous plant species of Korea was analyzed using a culture-based approach. Sixty one actinobacterial strains were isolated, and assigned to 15 genera based on 16S rRNA gene analysis. The members of the genus Streptomyces comprised 45.9% of the total isolates, followed by Micromonospora (18.8%),(More)
Over the past decades, hydrogels have been widely studied as biomaterials for various biomedical applications like implants, drugs and cell delivery carriers because of their high biocompatibility, high water contents and excellent permeability for nutrients and metabolites. Especially, in situ forming hydrogel systems have received much attention because(More)
OBJECTIVE Behavioral disturbances in dementia are extremely prominent and distressful, and often result in serious physical, social, and economic consequences. The authors compared the efficacy and tolerability of risperidone and haloperidol in the treatment of behavioral and psychological symptoms of dementia (BPSD) in institutionalized elderly Korean(More)
Development of biomaterials to control the fate of stem cells is important for stem cell based regeneration of bone tissue. The objective of this study is to develop functionalized electrospun fibers using a mussel-inspired surface coating to regulate adhesion, proliferation and differentiation of human mesenchymal stem cells (hMSCs). We prepared(More)
Composite nanofibers of poly(caprolactone) (PCL) and gelatin crosslinked with genipin are prepared. The contact angles and mechanical properties of crosslinked PCL-gelatin nanofibers decrease as the gelatin content increases. The proliferation of myoblasts is higher in the crosslinked PCL-gelatin nanofibers than in the PCL nanofibers, and the formation of(More)
