Intra-individual variance of the human plasma oxylipin pattern: low inter-day variability in fasting blood samples versus high variability during the day

Optical Intra-day Variability in Blazars

We selected a sample of a dozen blazars which are the prime candidates for simultaneous multi-wavelength observing campaigns in their outburst phase. We searched for optical outbursts, intra-day variability and short term variability in these blazars. We carried out optical photometric monitoring of nine of these blazars in 13 observing nights during our observing run October 27, 2006 − March 2...

Vocal Change Patterns During a Teaching Day: Inter- and Intra-subject Variability.

OBJECTIVES To describe the mean voice changes of 22 female teachers during a typical workday, examine the inter- and intra-subject variability, and establish a typology of different voice patterns during the workday. METHODS For each participant, fundamental frequency (F0), harmonics-to-noise ratio (HNR), jitter, and shimmer were measured on sustained vowels at the beginning and at the end of...

Day-to-day blood pressure variability and dementia

Modelling intra- and inter-day variability of NO2 concentrations in Portugal

Abstract. Nitrogen dioxide (NO2), is a pollutant that is toxic by inhalation and there is evidence that long-term exposure to this, at high concentrations, has adverse health effects, namely in respiratory and cardiovascular systems. The goal of this study is to characterize the spatial and temporal evolution of NO2 concentration levels, taking into account that environmental data often incorpo...

Day-to-day variability in home blood pressure is associated with cognitive decline: the Ohasama study.

Although an association between high blood pressure and cognitive decline has been reported, no studies have investigated the association between home blood pressure and cognitive decline. Home blood pressure measurements can also provide day-to-day blood pressure variability calculated as the within-participant SD. The objectives of this prospective study were to clarify whether home blood pre...
