Chemoresistance is a primary cause of treatment failure in cancer and common property tumor-initiating stem cells. Overcoming mechanisms chemoresistance, particularly cells, can markedly enhance therapy prevent recurrence metastasis. This study demonstrates that the delivery Epirubicin by nanodiamonds highly effective nanomedicine-based approach to overcoming chemoresistance hepatic The potent physical adsorption creates rapidly synthesized stable nanodiamond–drug complex promotes endocytic...
Chemoresistance is a prevalent issue that accounts for the vast majority of treatment failure outcomes in metastatic cancer. Among mechanisms resistance markedly decrease efficacy, efflux drug compounds by ATP-binding cassette (ABC) transporter proteins can impair adequate retention cancer cells required therapeutic cytotoxic activity. Of note, ABC transporters are capable effluxing several classes drugs clinical standards, including anthracyclines such as doxorubicin, well anthracenediones...
Hydrophilic titania (TiO(2)) nanoparticles were dispersed in solutions of polystyrene (PS), and the suspensions cast on glass surfaces. The effect drying temperature hydrophobic character PS/TiO(2) was investigated: static water contact angle increased with temperature, as-prepared coating could be adjusted from superhydrophilicity to superhydrophobicity just by controlling temperature. Moreover, superhydrophobic turning into a superhydrophilic one (CA < 5 degrees ) after UV illumination,...
A methylsilicone/phenolic resin/silica composite surface was prepared by a casting method. The wetting behavior of the investigated. It found that as-prepared can be varied from superhydrophilicity to superhydrophobicity as drying temperature increased. Methylsilicone/silica and phenolic surfaces were also comparisons. Both them cannot achieve superhydrophobicity. mechanism proposed explain this phenomenon.
Abstract Multi‐walled carbon nanotube arrays (CNTAs) of good quality are prepared in a high yield ∼7 wt.% by CVD at 850 °C, using rectified cyclohexane as the source. All CNTAs forming on inner wall quartz tube reactor quality, but those zone 40 – 60 cm away from entrance furnace show best degrees graphitization and alignment. The length these is ∼200 µm, their average growth rate during reaction (8 min) 25 µm min −1 , content MWCNTs iron 93.7 3.9 wt.%, respectively. effect temperature also...
Abstract Graphene oxide (GO) reinforcement to enhance the property of epoxy has been reported many times; with most papers focusing on how modify GO different functional groups achieve better dispersion. Here, importance preparation route coating systems performance was investigated. It found that a mixed polar/nonpolar solvent BuOH/xylene (3/1 vol/vol) best choice for forming epoxy/GO coatings. Furthermore, it when freeze‐dried sonicated curing agent trimethylhexamethylene diamine in mix...
Planar and channel optical waveguides were fabricated in Cu doped KTiOPO4 (KTP) substrates using Rb+:K+ ion exchange process annealing process. The effective refractive indices measured the m-line method index profiles of these calculated inverse WKB method. For Cu:KTP difference diffusion depth d change Δn at z− z+ surfaces can hardly be observed. This observation is different from KTP. Compared with undoped KTP larger, whereas smaller. At both are larger. light induced changes 0.476,...
Abstract We report the first demonstration of proton-exchanged optical planar waveguides in x-cut and z-cut LiNbO3 doped with 6 mol% ZnO using adipic acid as proton source. These exhibit a graded index profile which can be modeled by linear step function surface increase 0.135 0.14 for waveguides, respectively. The diffusion constant Do activation energy Q are characterized optically to 1.64×109 μm2/h 88.8 KJ/mol 1.478×109 91.25 rate along z-axis is slower than that x-axis, whereas on larger...
High power blue light generated by quasi phase matched (QPM) second harmonic generation (SHG) techniques is very attractive for high density optical storage. KTiOPO/sub 4/ (abbreviated as KTP) one of the most important materials used in QPM SHG. Since 1987 many kinds waveguides and devices have been demonstrated KTP substrates. However there still remains some technique problems, example, control duty cycle segmented well cracking waveguides. On other hand photolithography process...
