Shikonin has anticancer activity, but it has not yet been applied into clinical use. In the present study, shikonin was prepared using liposomes. We aimed to examine several aspects of sh-L (shikonin-containing liposomes): preparation, angiogenic suppression and cellular uptake through self-fluorescence. Sh-L were prepared using soybean phospholipid and cholesterol to form the membrane and shik...
The effect of hesperetin, naringenin and its glycoside form on the Sindbis neurovirulent strain (NSV) replication in vitro was studied. All flavanones tested were not cytotoxic on Baby Hamster cells 21 clone 15 (BHK-21). Antiviral effect was evaluated by a colorimetric assay using MTT (3-(4,5 dimethylthiazol-2-yl)-2,5-dipheyl-tetrazolium bromide) and by plaque reduction assay. Hesperetin and na...
Recently, biogenic synthesis of gold nanoparticles (AuNPs) has become a focus area in cancer research owing to the eco-friendliness and cost effectiveness synthetic method. In this study, aqueous extract Garcinia kola seed (AEGKs) was used for bio-reduction Au3+ Au0. The synthesised AEGKs-AuNPs characterised by ultraviolet-visible (UV-Vis) spectroscopy, dynamic light scattering (DLS), high-reso...
Rapid and accurate detection of Methicillin Resistant Staphylococcus aureus (MRSA) is an important role of clinical microbiology laboratories to avoid treatment failure. The detection of MRSA is based on phenotypic assays which require at least 24 h to perform. Detection of the mecA gene or of PBP 2a is the "gold standard", but not always available. The aim of this study was to evaluate a rapid...
The human umbilical cord is a source of numerous Mesenchymal Stem Cells (MSCs), making it as a potential source of allogeneic multipotent cell for bone tissue engineering. The aims of this study were to find: 1) Human Umbilical Cord Mesenchymal Stem Cells (hUCMSCs) phenotypic characterization, 2) The in-vitro osteogenic differentiation potential of hUCMSCs, 3) The cytotoxicity of gelatin solven...
BACKGROUND The prognostic value of cyclooxygenase-2 (COX-2) in human renal cell carcinoma (RCC) remains unclear. The purposes of this study are to elucidate the clinical significance of COX-2 in clear cell RCC (CCRCC) and to assess the treatment effect of COX-2 inhibition on CCRCC cell lines. METHODS Using tumor samples obtained from 137 patients who had undergone nephrectomy at Seoul Nationa...
Neurogenesis, recovery from nerve injury, neurodegeneration, and Parkinson's disease affect people's health, yet the underlying molecular mechanisms remain elusive. Here, we investigated the effect of ganglioside GM1 and neural growth factor (NGF) on neural stem cell (NSC) proliferation and differentiation in vitro to provide a scientific basis for comprehensive treatment of nervous system dise...
o bjectives: the aim of this study was to assess the cytotoxic effects and osteogenic activity of recombinant human bone morphogenetic protein (rhbmp2) and nano-hydroxyapatite (n- ha) adjacent to mg-63 cell line. mat erials and methods: to assess cytotoxicity, the 4,5-dimethyl thiazolyl-2,5-diphenyl tetrazolium bromide (mtt) assay was used. alkaline phosphatase (alp) activity and oste- ogenic a...
To explore the combined effects of environmental radio-frequency (RF) field and X-ray, mouse spermatocyte-derived (GC-1) cells were exposed to 1950 MHz RF field at specific absorption rate (SAR) of 3 W/kg for 24 h combined with or without X-ray irradiation at 6 Gy. After treatment, the cell proliferation level was determined by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (...
In this study, a novel compound was isolated, identified, and its chemical structure determined from the extract of roots Senna velutina. addition, we sought to evaluate anticancer potential molecule against melanoma leukemic cell lines identify pathways death involved. To end, anthraquinone isolated barks S. velutina, analyzed by HPLC-DAD, molecular nuclear magnetic resonance (NMR). Subsequent...
