In vivo nuclear magnetic resonance (NMR) monitoring requires a high-density cell suspension, where cell precipitation should be avoided. We have designed a miniaturized cell agitator that fits entirely into an 8-mm NMR probe but that, being mounted into the instrument, is situated outside of the sensitive area. The device consists of two glass tubes connected in a way that, when gas flow is blo...

BACKGROUND Emerging evidence indicates that accumulating physical activity in periods of less than 10 minutes, termed sporadic physical activity (SPA), has similar effects on health as a similar volume of bouted physical activity (BPA). The purpose of this study was to describe the volume and intensity of SPA in adults. METHODS Participants consisted of a representative sample of 6040 adults ...

Optimism and cynical hostility are associated with health behaviors and health outcomes, including morbidity and mortality. This analysis assesses their association with longitudinal vigorous physical activity (PA) in postmenopausal women of the Women's Health Initiative (WHI). Subjects include 73,485 women nationwide without history of cancer or cardiovascular disease (CVD), and no missing bas...

Physical inactivity and low resting heart rate variability (HRV) are associated with increased coronary heart disease incidence. In the Whitehall II study of civil servants aged 45-68 years (London, United Kingdom, 1997-1999), the strength of the association of moderate and vigorous activity with higher HRV was examined. Five-minute recordings of heart rate and HRV measures were obtained from 3...

The establishment of the Croatian National Spatial Data Infrastructure has started at the beginning of the 1990's. The main agitator of the activities was the State Geodetic Administration of the Republic of Croatia. They started to build the documentation that describe vision and goals, while through studies and pilot projects they developed procedures and exact steps for realization of the go...

[1] We use a global Ocean-Atmosphere General Circulation Model (OAGCM) to show that the major mountain ranges of the world have a significant role in maintenance of the Atlantic Meridional Overturning Circulation (AMOC). A simulation with mountains has a maximum AMOC of 18 Sv (1 Sv = 10 m s ) compared with 0 Sv for a simulation without mountains. Atlantic heat transport at 25°N is 1.1 PW with m...

Physical exercise has been related with both beneficial effects on the gastrointestinal tract as with adverse effects on the latter. Gastrointestinal bleeding is one of these. In general, gastrointestinal bleeding is transient and mild. However, some cases caused by intestinal ischemia can sometimes be more serious due to the amount of bleeding and the presence of mucosal lesions. We present th...

The isotopic documents of lake deposition are suitable potential means for studyingthe intercontinental, environmental and climatic conditions. In order to study theenvironmental and climatic conditions of Parishan area in Fars province in Holocene, a Corewas taken with the length of 2m from the Parishan lake sediment. From this core, kernel timeseries was provided from documents of carbon and ...
