PURPOSE To evaluate the feasibility and patient satisfaction with electrical impedance scanning (EIS) for early detection of breast cancer in young women. METHODS Women undergoing screening clinical breast examination, imaging, or biopsy were eligible for EIS examination with T-Scan 2000ED (Mirabel Medical Systems, Austin, TX). Multiple logistic(More)
The present study investigates factors mediating odor and social preferences in female house mice (Muc domesticus) based on the t-complex genotype of males. Previous studies in this laboratory showed that females prefer the odors of wild-type (+/+) males over those that carry lethal genes (+/t). The purpose of this study was to determine the genetic,(More)
Pregnancy block, whereby recently mated female mice abort their pregnancies when exposed to novel (strange) males, was studied in house mice (Mus domesticus) differing in t-complex genotype; t-mutations are deleterious and +/t females avoid +/t males as mates. The results of Experiment 1, in which the genotype of the female, stud male, and strange male was(More)
A new postprocessing algorithm was developed for the diagnosis of breast cancer using electrical impedance scanning. This algorithm automatically recognizes bright focal spots in the conductivity map of the breast. Moreover, this algorithm discriminates between malignant and benign/normal tissues using two main predictors: phase at 5 kHz and crossover(More)
TGF-β plays a dual role in breast carcinogenesis, acting at early stages as tumor-suppressors and later as tumor-promoters. TGF-β isoforms are expressed in breast tissues and secreted in milk, suggesting that analysis of levels in milk might be informative for breast cancer risk. Accordingly, we assessed TGF-β2 levels in milk from women who had undergone a(More)
Twenty-five percent of wild house mice are heterozygous (+/t) for a deleterious, recessive mutation at the t complex. In previous studies we have demonstrated that wild female house mice can discriminate +/+ from +/t males and show strong preferences for the odors of males who do not carry t mutations. In the present study we examine the extent to which(More)
