Dengue fever is one of the acute flavivrus-borne infectious diseases caused by dengue virus with four serotypes. To date, there are no efficient diagnostic tools available for monitoring the disease activity of dengue fever. It is needed to develop a diagnostic device with the characteristics of inexpensiveness, ease-to-use and robustness for the detection of dengue fever. In this study, we have developed...
AIM: To study the expression of survivin, an inhibitor of apoptosis protein, in human gastric carcinomas and gastric carcinoma models of rats. METHODS: With the method of immunohisto-chemical staining, we studied the expression of survivin in 20 cases of chronic gastritis and 56 cases of gastric carcinomas. We used N-methyl-N'nitro-N-nitrosoguanidine (MNNG) and high dose sodium-chloride diet to induce...
To investigate the apoptosis-inducing effect of Caspases-3 expressed by constructed eukaryotic vector on gastric cancer cell line SGC7901.PCR was employed to amplify the sequences of both small and large subunits of Caspases-3. Its products were separately cloned into the Sma I site of pBluescript KS+ to generate both plasmids pBS/SS and pBS/LS. The small subunit fragment was excised from plasmid...
Because of the overwhelming scattering of light in biological tissues, the spatial resolution and imaging depth of conventional fluorescent imaging is unsatisfactory. Therefore, we present a dual modality imaging technique by combining fluorescence imaging with high-resolution noninvasive photoacoustic tomography (PAT) for the study of an animal tumor model. PAT provides high-resolution structural...
