“The search
for new strategies to improve patient outcome and organ preservation is of great clinical interest in head and neck squamous cell carcinoma (HNSCC) treatment, and gene therapy is expected to play a promising role. In this study, we demonstrated the value of laser-induced stress waves (LISWs) as a novel method for nonviral gene transfer for gene therapy in HNSCC. The in vitro and in vivo transfection efficiency as well as in vitro cytotoxicity for HNSCC was investigated. Green fluorescent protein (GFP) expression and cell viability were analyzed in vitro after administration of a GFP-expressing plasmid or cationically modified GFP-expressing
plasmid with LISW application. Luciferase expression in xenograft tumors was also quantitatively analyzed in vivo. The GFP gene was successfully transfected into HNSCC cells in vitro CX-6258 5-Fluoracil solubility dmso by LISW application. The cationically modified plasmid demonstrated enhanced transfection efficiency. LISWs are not associated with adverse effects after application to cells in vitro. The reporter genes were also successfully transfected into HNSCC tumors in vivo by LISW application. This technique is site specific, safe, and easily applicable for practical purposes. LISW gene therapy with therapeutic factors that inhibit tumor growth therefore has the potential as a future treatment
for HNSCC.”
“Quantitative and qualitative changes in the content of elements in the solid and liquid phases occurred as the pulp moved through reactors during biooxidation of an ore flotation concentrate. The association of microorganisms were adapted for utilizing sulfur-containing substrates; however, the rate of their oxidation was insufficient, which led to an increase in the amount of sodium cyanide required for gold recovery. The replacement of one-fourth of the liquid phase of the pulp (density, 13%) with a mineral medium without an energy source, the fractional addition AZD9291 concentration of FeSO(4) center dot 7H(2)O (1 g/l per day), and the improvement of pulp aeration made it possible to increase the content of SO (4) (2-) by 80.7, 86.2, and 58.5%, respectively. When one-fourth of the liquid phase of the pulp (density, 24%) was replaced with a mineral medium without an energy source, the rate of additional oxidation of sulfide minerals increased, which increased the efficiency of gold extraction into solution and gold recovery on charcoal by 3.4 and 3.6%, respectively, and reduced sodium cyanide consumption by 3 kg/ton.”
“Contents Subinvolution of placental sites (SIPS) is the major cause of persistent sanguineous vaginal discharge after parturition in the bitch. Spontaneous remission is common but may take several months, and hence, medical therapy to end the discharge is often requested.
