BACKGROUND Human epidermal growth factor receptor–2 (HER-2) and tumor-associated glycoprotein 72 (TAG-72) have proven to be excellent molecular targets for cancer imaging and therapy. Trastuzumab, which binds to HER-2, is effective in the treatment of disseminated intraperitoneal disease when labeled with 213Bi or 212Pb. 213Bi-humanized CC49 monoclonal antibody (HuCC49ΔCH2), which binds to TAG-72, inhibits the growth of subcutaneous xenografts. A next logical step to improve therapeutic benefit would be to target tumors with both molecules simultaneously. METHODS Athymic mice bearing intraperitoneal human colon carcinoma xenografts were treated with a combination of trastuzumab and HuCC49ΔCH2 labeled with 213Bi administered through an intraperitoneal route. The sequence of administration also was examined. RESULTS Before combining the 2 monoclonal antibodies, the effective doses of 213Bi-CC49ΔCH2 and 213Bi-trastuzumab for the treatment of peritoneal disease were determined to be 500 μCi for each labeled antibody. Treatment with 213Bi-HuCC49ΔCH2 resulted in a median survival of 45 days and was comparable to the median survival achieved with 213Bi-trastuzumab. Each combination provided greater therapeutic efficacy than either of the agents given alone. However, the greatest therapeutic benefit was achieved when 213Bi-HuCC49ΔCH2 and 213Bi-trastuzumab were coinjected, and a median survival of 147 days was obtained. CONCLUSIONS Dual targeting of 2 distinct molecules in tumors such as TAG-72 and HER-2 with α-particle radiation resulted in an enhanced, additive, therapeutic benefit. The authors also observed that this radioimmunotherapeutic strategy was well tolerated.

“…This strategy is particularly efficient for polymer packaging films. Adhesion, printability properties, gas separation properties of polymer membranes were highly improved by fluorination . Low density polyethylene (LDPE) films exhibit intrinsically very poor printability, wettability and O 2 barrier properties.…”

International audienceLow Density Polyethylene (LDPE) films are treated by a combination of plasma treatment followed by direct fluorination. Plasma treatment is carried out either with ion bombardment or reactive conditions according to the gas(es) used. The properties of samples prepared by the two combinations (i) ion bombardment/fluorination; and (ii) reactive plasma/fluorination are compared to the films treated only with single fluorination or plasma. Combined treatment results in printability and barrier properties toward O2 enhancement and the maintenance of the barrier properties toward water. Contrary to the direct fluorination only, the two combinations allow stable surface properties to be achieved

“…Results and discussion SEM observations of treated surfaces O 2 -plasma), which is more pronounced for O 2 -plasma treated samples. In previous studies, 2,14,24 the researchers reported no significant increase in the surface roughness for PE, POM, PBT, and PA6 after LPP surface treatment. Moreover, an ablation of the outermost surface layers of the POM occurs in O 2 -treated samples after 1800 s, and this is evidenced by the appearance of the glass fibers that are embedded in the POM matrix, Figure 1(l), and this is due to the stronger oxidation effect of O 2 -plasma in comparison to that of Ar-plasma.…”

The effect of surface treatment of polyoxymethylene (POM) using low-pressure plasma (LPP) on its adhesive bonding was investigated. Three different types of adhesives were used. Examinations of single lap shear, scanning electron microscopy, contact angle measurements, and energy dispersive X-ray analysis were carried out. The results showed that the adhesion strength was apparently enhanced when treating surfaces by LPP using argon or oxygen plasma which increased with the treatment time. This increase was also dependent on the adhesive type. Moreover, glass fiber–reinforced POM showed better adhesion strength compared to that of unreinforced POM. An increase in the surface free energy exceeding 50 mN/m was observed after 600-s treatment time compared to untreated samples (39 mN/m), where the increase in polar component was more predominant. Surface topography observations showed a significant increase in the surface roughness with increasing the treatment time, mainly when using oxygen plasma. Finally, an increase in polarity and wettability due to changes in the chemical composition of the surface was also reported.
