Background Aortic pulse wave velocity (PWV) is considered as the “gold standard” measurement of arterial stiffness and is commonly calculated as the ratio between the distance separating two locations along the artery and the transit time (Δt) needed for the pressure or velocity wave to cover this distance. PWV is increasingly assessed by means of cardiovascular magnetic resonance (CMR). Our go...

Phase sensitive optical transmission measurements have been performed on three dimensional opal-based photonic crystals containing a planar defect. From numerical derivation of the measured phase, the group velocity has been retrieved. Strong modulations in the group velocity are seen to correlate with a recovery in the transmission inside the forbidden spectral interval, demonstrating the pres...

background: delayed reporting resulting in advanced stage disease is a common problem in indian cancer patients. this study analysed the impact of various sociodemographic and psychosocial factors on the delayed reporting to healthcare professional (hcp) in oral and oropharyngeal cancer patients. methods: this cross sectional observational study was conducted using a structured questionnaire. q...
