Toposelective vapor deposition of hybrid and inorganic materials inside nanocavities by polymeric templating and vapor phase infiltration.

Selective deposition of hybrid and inorganic materials inside nanostructures could enable major nanotechnological advances. However, inserting ready-made composites inside nanocavities may be difficult, and therefore, stepwise approaches are needed. In this paper, a poly(ethyl acrylate) template is grown selectively inside cavities condensation-controlled toposelective vapor deposition, and the polymer is then hybridized by alumina, titania, or zinc oxide.

Initial Studies with C-Vorozole PET Detect Overexpression of Intratumoral Aromatase in Breast Cancer.

Aromatase inhibitors are the mainstay of hormonal therapy in estrogen receptor-positive breast cancer, although the response rate is just over 50% and in vitro studies suggest that only two thirds of postmenopausal breast tumors overexpress aromatase. The goal of the present study was to validate and optimize PET with C-vorozole for measuring aromatase expression in postmenopausal breast cancer in vivo. Ten newly diagnosed postmenopausal women with biopsy-confirmed breast cancer were administered C-vorozole intravenously, and PET emission data were collected between 40 and 90 min after injection.

Deep Neural Networks Improve Radiologists' Performance in Breast Cancer Screening.

We present a deep convolutional neural network for breast cancer screening exam classification, trained, and evaluated on over 200000 exams (over 1000000 images). Our network achieves an AUC of 0.895 in predicting the presence of cancer in the breast, when tested on the screening population.
