Introduction: E-cadherin is expressed in most normal epithelial tissues. Loss of E-cadherin can cause dedifferentiation and invasiveness in human carcinomas, leading E-cadherin to be classified as a tumor suppressor. Therefore, the aim of this study was to investigate the effect of interval training on the expression of tumor suppressor gene E-cadherin in breast cancer-bearing BALB/c mice. Meth...
We report time-resolved single molecule fluorescence imaging of individual CdSe quantum dots that are functionalized with oligomeric conjugated organic ligands. The fluorescence intensity trajectories from these composite nanostructures display both a strong degree of blinking suppression and intensity fluctuations with characteristic recurrence times on the order of 10-60 s. In addition, fluor...
We propose a novel high-index-contrast waveguide structure capable of light strong confinement and guiding in low-refractive-index materials. The principle of operation of this structure relies on the electric field (E-field) discontinuity at the interface between high-indexcontrast materials. We show that by using such a structure the E-field can be strongly confined in a 50-nm-wide low-index ...
E. Diener, R. J. Larsen, S. Levine, and R. A. Emmons (1985) distinguished between intensity and frequency as separable components in repeatedly measured affect. In this article, an improved way of differentiating intensity and frequency of affect is proposed that permits one to measure affect intensity separately for each emotion of interest. The results of 3 studies using this method provide f...
Seeded free electron lasers theoretically have the intensity, tunability, and resolution required for multiphoton spectroscopy of atomic and molecular species. Using the seeded free electron laser FERMI and a novel detection scheme, we have revealed the two-photon excitation spectra of dipole-forbidden doubly excited states in helium. The spectral profiles of the lowest (-1,0)(+1) (1)S(e) and (...
• The strength and consistency of genotypic differences in disease resistance determine the potential for resistance evolution in host populations that rely on vegetative reproduction. Here we surveyed infection intensity of host genotypes across space and time to estimate genotypic and environmental effects on quantitative disease resistance. • Cloned fragments of 12 Euthamia graminifolia geno...
Thirty-five healthy men were matched and randomly assigned to one of four training groups that performed high-intensity strength and endurance training (C; n = 9), upper body only high-intensity strength and endurance training (UC; n = 9), high-intensity endurance training (E; n = 8), or high-intensity strength training (ST; n = 9). The C and ST groups significantly increased one-repetition max...
Efficacy and costs of 3 levels of medical-behavioral treatment intensity in conjunction with nicotine replacement therapy (NRT) were compared in 240 one-pack-a-day smokers: (a) a low-intensity (LI) group that received 8 weeks of NRT (n = 80) and 1 advice and education (A&E) session with a nurse practitioner (NP); (b) a moderate-intensity (MI) group that was provided NRT and 4 A&E sessions with ...
Electron–positron pair production from vacuum in an electromagnetic field created by two counterpropagating focused laser pulses interacting with each other is analyzed. The dependence of the number of produced pairs on the intensity of a laser pulse and the focusing parameter is studied with a realistic three-dimensional model of the electromagnetic field of the focused wave, which is an exact...
Figure 1 of the article by Birjandian et al. (2013) contained a minor error in the legend, which we hereby rectify. In the original figure legend panel (C) is described as two examples of whole cell patch recordings made from layer II and layer III neurons. But in fact panel (C) correspond to normalized change in F/F vs. stimulus intensity from 8 recordings in the layer II. Panels (D,E) corresp...
