Splet19. maj 2024 · To assess the presence of functional epithelial metabolic changes at the onset of cervical precancers, we initially characterized the intracytoplasmic NAD (P)H TPEF intensity fluctuations that are influenced mainly by the spatial distribution and organization of mitochondrial formations, since NAD (P)H fluorescence is enhanced ∼10-fold when … SpletI am doing my last year as PhD student in in optical nanoscopy (Biophotonics). I have been implementing a label-free polarization-resolved light scattering called Circular Intensity Differential Scattering (CIDS) integrated with two-photon excitation fluorescence (TPEF) microscopy as benchmark of genetic material that is sensitive to chiral organizations to …

Splet01. jun. 2024 · Like all nonlinear imaging techniques, TPEF- and two-photon FLIM-imaging require very high peak power with low duty cycle. The high power is necessary for a strong signal and the low duty cycle ensures that the average power is kept on a moderate level in order to avoid sample damage. Splet30. nov. 2016 · Endogenous NADH TPEF intensity and mitochondrial dynamics changes in response to arterial occlusion and reperfusion. ( A) Top: Representative scaled in vivo NADH intensity TPEF images for upper and lower human skin layers before, during, and after arterial occlusion. Each epidermal layer was imaged every 10 s for 3 min in each … troubleshoot ping

SpletWhen the cells were treated with rapamycin (50 μg/ml), a pharmacologic agent that induces autophagy (37), the TPEF intensity increased at 400-450 nm, and de- creased at 550-600 nm (Fig. 2M: 2 h). This outcome indicates the activation of lysosomes and breakdown of mitochondria, a result consistent with autophagy. SpletUV-TPEF Imaging(normalize前) UV-TPEF Imaging(normalize後) normalize処理について ... The intensity values are stretched to cover the entire range of possible values. While doing so, black-out at most 2% of the pixels and white-out at most 1% of the pixels. Note that as of ImageMagick 6.4.7-0, -normalize is equivalent to -contrast-stretch ... SpletI took part in a project that investigated how low-intensity vibrations affect mesenchymal stem cells' ability to form gap junctions as they differentiate into either adipogenic or osteogenic tissues, and consequently, the capacity of low-intensity vibrations to be used in bone fracture healing. ...
