Estimation the tumor temperature in magnetic nanoparticle hyperthermia by infrared thermography: phantom and numerical studies

Publication date: Available online 11 July 2018Source: Journal of Thermal BiologyAuthor(s): Ming Ma, Yu Zhang, Ning GuAbstractThe treatment of cancer by hyperthermia requires prediction, monitoring and control of the temperature within the tumor. Infrared thermography (IRT) was presented in this paper as a noninvasive temperature monitoring method used in magnetic nanoparticle hyperthermia (MNH). We tried to use this surface temperature measurement method to get information about the intratumoral temperature. Experimental in vitro MNH studies were performed on gel tumor-tissue phantoms which were constructed to simulate the real tumor and overlying healthy tissue. Magnetic nanoparticles were dispersed uniformly in the tumor part of phantom. During the process of in vitro MNH, an alternating magnetic field (AMF) was applied for heating, an IR thermal camera monitored the surface temperature and a fiber optical sensor measured the tumor temperature. A numerical finite element models of thermal analyses was built to simulate the MNH phantom experiments. Both experimental and numerical results indicate that the temperature difference between the surface hot spot and the tumor inner will reach a fixed value while the heating is going on. This value is correlated to factors such as heat generation of hyperthermia, size and depth of the tumor. A regression functions is established to describe the relationship, which is helpful for fast tumor inner temperature estimation by infrared ...

CONCLUSIONS: There is an urgent need for further research that can help guide clinical decision-making with patients who may not benefit from LCS owing to coexisting chronic illness. This statement establishes a research framework to address essential questions regarding how to incorporate and communicate risks of comorbidities into patient selection and decisions regarding LCS.

Abstract Anthracyclines are frequently used to treat many cancers including triple negative breast cancer, which is commonly observed in African-American women (AA), and tend to be more aggressive, carry worse prognoses, and are harder to manage because they lack molecular targets. Although effective, anthracyclines use can be limited by serious side effects and eventually the development of drug resistance. In S. cerevisiae, mutants of HOM6 display hypersensitivity to doxorubicin. HOM6 is required for synthesis of threonine and interruption of the pathway leads to accumulation of the threonine intermediate L-aspa...

ve; A Abstract The study presents a report of 58 metastatic cancer patients who developed osteonecrosis of the jaws after being treated with zoledronic acid and taxanes, plus corticosteroids. A retrospective analysis of data registered in the archives of two Italian osteonecrosis of the jaws treatment centers, who are based at the University of Messina and at the University of Palermo, was performed in order to study, in these patients, demographic data and characteristics such as frequency of cancer location, lines of therapy, frequency of cancer drugs, presence/absence of oral trigger, number, location, and stag...

LcnRNA can regulate the 3D architecture of the enhancer cluster at the target gene locus, relevant to analogous lncRNA-protein coding gene pairs. X inactive specific transcript (Xist) plays a critical role in the process and biological function of lcnRNAs. The lncRNA Jpx, Xist activator, is a nonpro...

Authors: Furusawa Y, Itai S, Yamada S, Kaneko MK, Kato Y Abstract Telomerase reverse transcriptase (TERT) is the main catalytic subunit of telomerase-associated protein machinery. Upregulation of TERT at the transcriptional level results in immortal cell phenotype associated with cancer. To date we have developed eight anti-TERT monoclonal antibodies (mAbs) (TMab-4, TMab-5, TMab-6, TMab-7, TMab-9, TMab-10, TMab-11, and TMab-12) by immunizing mice with synthetic peptides (302-QHHAGPPSTSRPPRPWDTPC-321) of TERT. We further characterized those epitopes using enzyme-linked immunosorbent assay, and here we discuss the cr...

CONCLUSIONS Our findings suggested that tumor overexpression of DNMT1 and DNMT3A is associated with tumor aggressive behavior and high-methylation status in pituitary adenomas. Our data support a possible role of DNMT1 and DNMT3A in TSG promoter methylation leading to pituitary adenoma invasion and suggest that inhibition of DNMTs has the potential to become a new therapeutic approach for invasive pituitary adenoma.
