Seasonal Variations of complete blood count and inflammatory biomarkers in the us population analysis of nhanes data
PLOS ONE, 2015Co-Authors: Emanuela TaioliAbstract:Background Recent studies reported Seasonal differences in gene expression in white blood cells, adipose tissue, and inflammatory biomarkers of the immune system. There is no data on the Seasonal Variations of these biomarkers in the US general population of both children and adults. Then aim of this study is to explore the Seasonal trends in complete blood count (CBC), and C-reactive protein (CRP) in a large non-institutionalized US population. Methods Seven cross-sectional data collected in the National Health and Nutrition Examination Survey (NHANES) during 1999–2012 were aggregated; participants reporting recent use of prescribed steroids, chemotherapy, immunomodulators and antibiotics were excluded. Linear regression models were used to compare levels of CBC and CRP between winter-spring (November-April) and summer-fall (May-October), adjusting for demographics, personal behavioral factors, and chronic disease conditions. Results A total of 27,478 children and 36,644 adults (≥18 years) were included in the study. Levels of neutrophils, white blood cell count (WBC), and CRP were higher in winter-spring than summer-fall (p≤0.05). Red blood cell components were lower in winter-spring than in summer-fall, while the opposite was seen for platelets. Conclusions This large population-based study found notable Seasonal Variations in blood cell composition and inflammatory biomarkers, with a more pro-inflammatory immune system seen in winter-spring than summer-fall. The red blood cell patterns could have implications for the observed cardio-vascular Seasonality.

Seasonal Variations of soil microbial biomass and activity in warm and cool season turfgrass systems
Soil Biology & Biochemistry, 2011Co-Authors: Huaiying Yao, Daniel C. Bowman, Wei ShiAbstract:Plant growth can be an important factor regulating Seasonal Variations of soil microbial biomass and activity. We investigated soil microbial biomass, microbial respiration, net N mineralization, and soil enzyme activity in turfgrass systems of three cool-season species (tall fescue, Festuca arundinacea Schreb., Kentucky bluegrass, Poa pratensis L., and creeping bentgrass, Agrostis palustris L.) and three warm-season species (centipedegrass, Eremochloa ophiuroides (Munro.) Hack, zoysiagrass, Zoysia japonica Steud, and bermudagrass, Cynodon dactylon (L.) Pers.). Microbial biomass and respiration were higher in warm- than the cool-season turfgrass systems, but net N mineralization was generally lower in warm-season turfgrass systems. Soil microbial biomass C and N varied Seasonally, being lower in September and higher in May and December, independent of turfgrass physiological types. Seasonal Variations in microbial respiration, net N mineralization, and cellulase activity were also similar between warm- and cool-season turfgrass systems. The lower microbial biomass and activity in September were associated with lower soil available N, possibly caused by turfgrass competition for this resource. Microbial biomass and activity (i.e., microbial respiration and net N mineralization determined in a laboratory incubation experiment) increased in soil samples collected during late fall and winter when turfgrasses grew slowly and their competition for soil N was weak. These results suggest that N availability rather than climate is the primary determinant of Seasonal dynamics of soil microbial biomass and activity in turfgrass systems, located in the humid and warm region.

Seasonal Variations of seawater pco2 and sea air co2 fluxes in a fringing coral reef northern south china sea
Journal of Geophysical Research, 2016Co-Authors: Hongqiang Yan, Meixia Zhao, Qi Shi, Tianran Chen, Guohui Liu, Yehui Tan, Yinghui WangAbstract:Evidence based on four field surveys conducted between July 2009 and April 2011 indicates that both sea surface partial pressures of CO2 (pCO(2)) and sea-air CO2 fluxes at Luhuitou fringing reef in Sanya, Hainan Island, northern South China Sea (SCS) are subject to significant Seasonal Variations. The diurnal variation of seawater pCO(2) ranges from 264 to 579 mu atm in summer, which is much larger than that in autumn (152-335 mu atm), in winter (84-260 mu atm), and in spring (114-228 mu atm). The sea-air CO2 flux in summer (similar to 9.6 mmol CO2 m(-2) d(-1)) is also larger than that in other seasons (i.e.,similar to 3 mmol CO2 m(-2) d(-1) in spring, similar to 3.5 mmol CO2 m(-2) d(-1) in autumn, and similar to 2.7 mmol CO2 m(-2) d(-1) in winter). The atmospheric pCO(2) in this reef shows small diurnal and Seasonal Variations. The integration of the time-series pCO(2) data shows that the reef area is a weak source of atmospheric CO2 at similar to 0.54 mol CO2 m(-2) yr(-1). Further analyses indicate that the Seasonal Variations of the surface seawater pCO(2) in Luhuitou fringing reef are mainly affected by Seasonally-dependent biological metabolic processes (organic processe and inorganic process), and that the organic process play a more important role than the inorganic process. Seasonal sea surface temperature (SST) Variations and hydrodynamic processes may also have some influence on seawater pCO(2) variation.

ORIGINAL PAPER Seasonal Variations in vertical migration of glacier lanternfish,
2016Co-Authors: Benthosema Glaciale, Eivind Dypvik, Anders Rostad, Stein KaartvedtAbstract:Abstract The Seasonal Variations in glacier lanternfish (Benthosema glaciale) vertical distribution and diel vertical migration (DVM) were studied by use of a bottom-moun-ted upward-facing 38 kHz echo sounder deployed at 392 m depth and cabled to shore in Masfjorden (*60520N, *5240E), Norway. Acoustic data from July 2007–October 2008 were analyzed, and scattering layers below *220 m during daytime were attributed to glacier lanternfish based on net sampling in this, and previous studies, as well as from analysis of the acoustic data. At these depths, three different diel behavioral strategies were apparent: normal diel vertical migration (NDVM), inverse DVM (IDVM), and no DVM (NoDVM). NoDVM was present all year, while IDVM was present in autumn and winter, and NDVM was present during spring and summer. The sea-sonal differences in DVM behavior seem to correlate with previously established Seasonal distribution of prey. We hypothesize that in regions with Seasonally migrating zooplankton, such as where calanoid copepods overwinter at depth, similar plasticity in DVM behavior might occur in other populations of lanternfishes
