In picosecond time-resolved Raman spectroscopy, the depolarization ratio is expected to change as the time delay is varied if an anisotropy distribution of the excited state is introduced using linearly polarized pumping light and the time resolution of the measuring system is shorter than the ...

which triggerapoptosis(Tian, Zhao, Zeng, Zhang, & Zheng, 2016). The induction of apoptosis was shown by an increase in the ratio of bax (apoptosis inducer) to bal2 (apoptosis suppressor protein).Fig. 2depicts the mechanism of polysaccharides functioning via depolarization of mitochondrial membrane...
By hypoxia-induced contraction of pulmonary arterial smooth muscle cells (PASMCs), pulmonary capillary blood flow is redirected to alveolar areas of high oxygen partial pressure (pO 2 ), thus maintaining the ventilation-perfusion ratio. Although the principle of HPV was recognized decades ago the ...
[47]. To ensure the surface of the samples as dry and clean as possible, the sintered samples taken out from the muffle furnace were immediately placed in the vacuum drying oven at 100 °C for 24 h and then to perform the XPS measurement. The integral ratio was calculated and illustrated...
The experimental volume fraction of ZnO can be basically quantified according to the area ratio of different components provided in the scanning electron micrograph (SEM) (Fig. 1a). For composi- tions with small amount of ZnO (x ¼ 0.1 and 0.2), the volume fraction cannot be experimentally...

The RyR1 forms a checkerboard-like array of tens to hundreds of channels in the terminal cisternae, and 50% of them are associated with Cav1.1 (in a 4:1 ratio) (Franzini-Armstrong et al., 1999). It is possible that RyR1s not directly linked to Cav1.1 are activated by Ca2+ions r...
The depolarization ratios increased evidently from visible to UV excitation, and were discussed in relation to the ratio of the scattering tensor components.Y.Dept.UdagawaDept.M.Dept.IijimaDept.M.Dept.ItoDept.WileyJournal of Raman Spectroscopy...
