Characteristics of Thermosensitive and Targeted F127-Triethoxysilane/Gold Nanorod Combined with Photothermal Therapy in Tumor Model Mice

Even with all the recent technological improvements, cancer remains to be the disease with the highest impact on global health. Due to obviously disadvantages or limitations on traditional therapy, researchers are engaged to search for safely and effective methods in cancers’ therapy. Photothermal therapy (PTT) has been employed in treating cancers and several of other diseases. In this study, novel thermosensitive and targeting nanoparticle, C225-silane-F127/gold nanorod (C-SFGR) combined with PTT was investigated in EGFR-overexpressing xenografts mice model. For better light to heat transformation exposed with 808 nm near-infrared (NIR) laser, the diameter of thermosensitive C-SFGR was designed at about 120 nm. To address the biocompatibility, the viability of A549 cell line was greater than 80% under high concentrations of C-SFGR (1,000 μg/mL), indicating its low cytotoxicity. After intravenous injection of C-SFGR and combined with NIR treatment for 2 min in A549 bearing mice, tumors were almost completely shriveled after 2 weeks. For developing as theranostic agent, C-SFGR was then labeled with 67Ga, with radiochemical purity over 98%. These present results suggest that C-SFGR could be also applied as a SPECT-imaging agent and as an effective antitumor agent.

Flow Dynamics of the Homogeneous and Heterogeneous Reactions with an Internal Heat Generation and Thermal Radiation between Two Squeezing Plates

This paper explores the time dependent squeezing flow of a viscous fluid between parallel plates with internal heat generation and homogeneous/heterogeneous reactions. The motive of the present effort is to upgrade the heat transformation rate for engineering and industrial purpose with the rate of chemical reaction. For this purpose the equations for the conservation of mass, momentum, energy and homogeneous/heterogeneous reactions are transformed to a system of coupled equations using the similarity transformation. According to HAM, with the proper starting assumptions and other factors, a similarity solution may be found. On the way to verifying the validity and correctness of HAM findings, we compare the HAM solution with numerical solver programme BVP4c to see whether it matches up. The results of a parametric inquiry are summarized and presented with the use of graphs.

Numerical Modelling on the Influence of Source in the Heat Transformation: An Application in the Metal Heating for Blacksmithing

Many physical problems, such as heat transfer and wave transfer, are modeled in the real world using partial differential equations (PDEs). When the domain of such modeled problems is irregular in shape, computing analytic solution becomes difficult, if not impossible. In such a case, numerical methods can be used to compute the solution of such PDEs. The Finite difference method (FDM) is one of the numerical methods used to compute the solutions of PDEs by discretizing the domain into a finite number of regions. We used FDMs to compute the numerical solutions of the one dimensional heat equation with different position initial conditions and multiple initial conditions. Blacksmiths fashioned different metals into the desired shape by heating the objects with different temperatures and at different position. The numerical technique applied here can be used to solve heat equations observed in the field of science and engineering.
