Using the characteristics of T cell mitogen called lectin protein from the jack-beam Canavalia ensiformis Concanavalin A (Con_A) with dual activities, cytotoxicity and immunomodulation, we have shown it has a therapeutic effect on hepatoma. Injection of Con_A can eradicate the established malign tumor, because Con_A can induce tumor cell autophagic, cell-programmed death, as well as activate th...

PURPOSE Selective targeting of the retinal pigment epithelium (RPE) with repetitive laser pulses that minimize thermal damage to the adjacent photoreceptors is a promising new therapeutic modality for RPE-related retinal diseases. The selectivity of an alternative, more versatile scanning approach was examined in vivo by using a broad range of scanning parameters. METHODS Acousto-optic deflec...

BACKGROUND AND OBJECTIVES Wavelengths near ∼1,720 nm are of interest for targeting fat/lipid-rich tissues due to the high absorption coefficient of human fat and low water scattering and absorption. In this study, a 1,708 nm laser was built and shown to selectively target fat/lipid adjacent to porcine heart and dermis and then used to damage dermal sebaceous glands in human skin. STUDY DESIGN A...

mammalian expression systems, due to their capacity in post-translational modification, are preferred systems for biopharmaceutical protein production. several recombinant protein systems have been introduced to the market, most of which are under clinical development. in spite of significant improvements such as cell line engineering, introducing novel expression methods, gene silencing and pr...

in the present study, an attempt was made to develop galactosylated albumin nanoparticles of cimetidine for treatment of acetaminophen induced hepatotoxicity. by developing the galactosylated nanoparticulated delivery of cimetidine the required action of drug at the target site i.e at liver can be provided. the advantage of targeting helps to reduce the systemic side effects which may be occur ...

Herein we report the possibility of using green and red emitting silica-coated cadmium selenide (CdSe) quantum dots (QDs) for remarkable stem and cancer cellular imaging, efficient cellular uptake and fluorescence imaging of semi and ultra-thin sections of tumor for in vivo tumor targeted imaging applications. The comparative studies of high contrast cellular imaging behaviours of the silica-co...

LASER CHARACTERISTICS aser surgery of skin conditions having cosmetic implications has revealed the profound psychological benefits which are unmatched by any other modality Laser light is monochromatic, bright, unidirectional and of treatment either with or without a knife. An increasingly coherent. sophisticated understanding of the biophysics of lasertissue interactions has lead to a more ef...

Since its discovery in the 1940s, retinal photocoagulation has evolved immensely. Although the first photocoagulators utilised incandescent light, it was the invention of laser that instigated the widespread use of photocoagulation for treatment of retinal diseases. Laser permits choice of electromagnetic wavelength in addition to temporal delivery methods such as continuous and micropulse mode...

OBJECTIVES Low power diode Iaser (830 nm) irradiation is a useful analgesic tool in superficial pain. Pulse laser irradiation allows us to increase the laser power because the non-irradiation time reduces heating effects and/or direct tissue damage at the irradiation area. This new irradiation device using pulse laser was applied to the dorsal skin to investigate the effects on the micturition ...
