Nanodiamond in a 2-5-nm size interval (which is typical for an appearance of quantum confinement effect) show Raman spectra composed of 3 bands at 1325, 1600, and 1500 cm-1 (at the 458-nm laser excitation) which shifts to 1630 cm-1 at the 257-nm laser excitation. Contrary to sp2-bonded carbon, relative intensities of the bands do not depend on the 458- and 257-nm excitation wavelengths, and a h...

The substituted activator ions Eu(2+) in the β-Ca3(PO4)2-type structure, Ca9NaMg(PO4)7 compound, have been studied as emission centers, as well as structural probes. The crystal structure and crystallographic sites of Eu(2+) in Ca9NaMg(PO4)7 have been identified by Rietveld refinements, electron paramagnetic resonance (EPR) spectroscopy analysis and combined photoluminescence spectral analysis,...

Tertiary lymphoid structures (TLSs) are useful biomarkers for predicting the prognosis and assessing response to immunotherapy in many cancers. In Merkel cell carcinoma (MCC), however, TLSs have only been examined MCPyV-positive cases were reported not correlate with prognosis. Here, we prognostic value of 61 patients MCC, including both MCPyV-negative cases. TLS-positive samples had a signific...

We determined the contributions of angiotensin II type 1 receptor (AT1) stimulation, adrenergic stimulation, and autonomic activation to pressure overload-induced c- fos expression in the adult rat heart in vivo. c- fos expression was increased in pressure-overloaded hearts created by aortic banding compared with sham-operated rats (458 ± 100% vs. sham, P < 0.05). GR-138950, a selective AT1 ant...

The dynamic range, sensitivity, and dark decay of holographic recording of wavelength 458 nm in LiNbO(3) crystals doped with 0.2-at. % Mn with different oxidation states have been measured. The measured sensitivity is 0.5 cm/J and is found to be independent of the oxidation state, and the largest M/# obtained is 12/mm (extraordinary light polarization; light wavelength, 458 nm). This combinatio...
