Dielectric properties of muscle and tissue-mimicking solutions for microwave medical imaging applications.
Dielectric properties of muscle and tissue-mimicking solutions for microwave medical imaging applications. Phys Med Biol. 2019 Mar 07;: Authors: Pollacco DA, Caligari Conti M, Farrugia L, Schembri Wismayer P, Farina L, Sammut CV Abstract The aim of the present study was to synthesize mixture solutions which can accurately mimic the dielectric properties of biological tissues, specifically muscle and adipose tissues between 500 MHz and 50 GHz. Mixtures utilizing concentrations of bovine serum albumin (BSA) dissolved in phosphate buffered saline (PBS) and Ringer's solutions were synthesized to mimic in vivo and ex vivo muscle tissues. Solutions consisting of concentrations of peanut oil and Triton X 100 (TX) in PBS and Ringer's solutions were also synthesized to mimic in vivo and ex vivo adipose tissue. Results were then analysed and compared to measured dielectric properties of in vivo and ex vivo biological tissues from another previous study. Good agreement with said dielectric property measurements were obtained since the solutions from this study yielded low RMSE and RMSRE values. This implied that such solutions can be utilized in the construction of human body phantoms for narrowband and ultra-wideband microwave devices for near field breast cancer imaging.

Harada, Kazuaki Nakashima, Takayoshi Uematsu, Takashi Sugino, Seiichirou Nishimura, Kaoru Takahashi, Yukiko Tadokoro, Tomomi Hayashi, Junichiro Watanabe, Shogo NakamotoAbstractA 63-year-old woman was referred to our hospital for breast cancer treatment. She had a large HER2-positive breast tumor on her left breast, and received neoadjuvant chemotherapy. After treatment, a shrunk spiculated mass with calcification-like high density was detected on mammography, and MRI revealed a large strong susceptibility artifact. Surgical specim...
CONCLUSIONS: Epidemiological figures emerging from this study confirm that trends in Lebanon are in line with a global pattern of decreasing age at menarche. Urban-rural differences suggest that higher caloric content of diet and consequent early overweight, more evident in urban areas, are likely determinants of younger menarche. Evidence from this study calls for an urgent implementation of comprehensive multisectoral obesity prevention in children in Lebanon. PMID: 31519350 [PubMed - as supplied by publisher]
ConclusionsThese findings suggest an association between theeNOS c.-813C>T polymorphism and the development of proteinuria in mBC patients receiving a bevacizumab-based chemotherapy.
