consumption on inflammatory and cardiovascular risk factors among overweight and obese female adults
background: soymilk replacement in the diet might have beneficial effects on inflammation and cardiovascular risk factors for non-menopausal overweight and obese female adults. we evaluated the effects of soymilk compared to cow's milk on inflammation and cardiovascular risk factors among overweight and obese female adults. materials and methods: this was a cross-over randomized clinical trial ...
Deserts can be considered as one of the main sources dust emissions they are highly vulnerable to wind erosion, i.e. The lack vegetative cover, well low soil wetness, contribute release particles by erosion. present study examines seasonal variation in sand and storms (SDSs) originating from war-impacted semi-arid bare lands affected chemical warfare located southwest Iran for period 2007–2018....
Lufft’s CHM 15k “Nimbus” ceilometer and a collocated Cimel sunphotometer were used, in tandem with satellite data, to observe the transport of atmospheric aerosols over Raciborz, Poland, during an exceptionally warm month of August 2015. Two distinct periods are identified: increased aerosol optical thickness (AOT) values, exceeding 0.65, during August 6 to 13 concurrent with the planetary boun...
this study was carried out to assess the effects of alfalfa hay level and replacing corn grain by other grains in starter on daily feed intake, average daily gain (adg) and feed efficiency (fe) of pre and post-weaning dairy calves during the pre and post-weaning periods. for this purpose, a database meta-analysis used in the present study. statistical analyses were performed using proc mixed in...
Phyto- and zooplankton in Arctic sub-Arctic seas show very strong seasonal changes diversity biomass. Here we document the variability mesozooplankton community structure a fjord Northern Norway based on monthly sampling between November 2018 February 2020. We combined traditional morphological identification with DNA metabarcoding of 313 base pair fragment COI gene. This approach allowed us to...
We present the longest tree-ring chronology to date in northeastern North America (2233 years; 227 BCE – 2005 CE), resulting from several research projects conducted at subarctic treeline northern Quebec. This raw of width includes 464 black spruce (Picea mariana (Mill.) B.S.P.) shrubs (krummholz) growing wetlands and preserved within peatlands. An indexed series 152 erect trees that have lived...
STUDY DESIGN Single-subject with repeated measures. OBJECTIVES To determine if runners can use real-time visual feedback from an accelerometer to achieve immediate reductions in tibial acceleration and vertical-force loading rates. BACKGROUND Stress fractures are a common injury among runners. Previous studies suggest that runners with higher than normal tibial acceleration and vertical-for...
The increased frequency of climate extremes associated with ongoing change has the potential for significant impacts on maize grain yield in maize-producing regions worldwide. In this study, we used a modeling approach to investigate effects different types climatic Northeast China. We combined annual mean air temperature and accumulated precipitation data divided years into 9 categories, using...
Background: Previous studies have indicated that Ramadan fasting has beneficial effects on cardiovascular risk factors, specially blood pressure and heart rate. In the present study, the effect of Ramadan fasting on 24-hour ambulatory blood pressure and heart rate has been investigated. Materials and Methods: This prospective observational study was conducted on two groups of individuals. Six p...
Abstract We perform intensity variability analyses (photometric analyses: the Lomb–Scargle periodogram, autocorrelation, and wavelet) asteroseismic analysis of 92 Kepler solar-like main-sequence stars to understand reliability measured stellar rotation periods. focus on 70 without reported companions, classify them into four groups according quarter-to-quarter variance period precision period. ...
