“…Linearity between the net PM 10 concentration and the logarithm of height was verified using Pearson correlation. As practiced in biostatistics (Colton, 1974; Gherman and Mironiuc, 2012; Lehman et al, 2009) and other research areas (USDA, 2012), a Pearson correlation criterion of 0.75 was applied to indicate strong and robust linearity. Thus, hourly data points with Pearson correlation coefficients ≥0.75 were used in flux computation.…”

Data on air emissions from open-lot beef cattle () feedlots are limited. This research was conducted to determine fluxes of particulate matter with an aerodynamic diameter ≤10 μm (PM) from a commercial beef cattle feedlot in Kansas using the flux-gradient technique, a widely used micrometeorological method for air emissions from open sources. Vertical PM concentration profiles and micrometeorological parameters were measured at the feedlot using tapered element oscillating microbalance PM samplers and eddy covariance instrumentations (i.e., sonic anemometer and infrared hygrometer), respectively, from May 2010 through September 2011, representing feedlot conditions with air temperatures ranging from -24 to 39°C. Calculated hourly PM fluxes varied diurnally and seasonally, ranging up to 272 mg m h, with an overall median of 36 mg m h. For warm conditions (air temperature of 21 ± 10°C), the highest hourly PM fluxes (range 116-146 mg m h) were observed during the early evening period, from 2000 to 2100 h. For cold conditions (air temperature of -2 ± 8°C), the highest PM fluxes (range 14-27 mg m h) were observed in the afternoon, from 1100 to 1500 h. Changes in the hourly trend of PM fluxes coincided with changes in friction velocity, air temperature, sensible heat flux, and surface roughness. The PM emission was also affected by the pen surface water content, where a water content of at least 20% (wet basis) would be sufficient to effectively reduce PM emissions from pens by as much as 60%.

“…been shown to enhance insulin resistance, predominantly in the liver, whereas adiponectin enhances fat oxidation in skeletal muscle and lowers glucose production in the liver. Furthermore, there is accelerated atherosclerosis in subjects with low adiponectin levels and resistin, expressed in activated macrophages, suggesting that these adipokines may have a direct role in atherosclerosis [ 5 ] . Growth hormone is an important modulator in the production of adipocyte-derived adipokines [ 6 , 7 ] .…”

Metabolic Parameters and Adipokine Profile in Growth Hormone Deficient (GHD) Children Before and After 12-Month GH Treatment

et al. 2013

It is a common knowledge that GH exhibits a large number of metabolic effects, involving lipid and glucose homeostasis. The aim of the study was to investigate the effect of one year GH therapy on metabolic parameters and adipokines in GH deficient (GHD) children. Sixteen prepubertal children (11 M and 5 F) with complete GHD (age range: 3.4-14.7 years) and 20 (13 M and 7 F) age and sex-matched healthy children (age range: 4.6-12.3 years) were studied. Blood was collected from patients before starting GH therapy (0.025 mg/kg/day) and one year later, and from healthy children to measure adiponectin, leptin, osteoprotegerin, resistin, interleukin (IL)-6, tumor necrosis factor (TNF)-α levels, and other glucose and lipid metabolism parameters. Adiponectin and resistin levels were significantly higher (49980 ng/ml vs. 14790 ng/ml and 11.0 pg/ml vs. 6.3, respectively) in GHD children before GH therapy than in controls. Serum IGF-I levels (p=0.0001) and height SDS (p<0.0001) significantly increased after 12 months' of GH therapy. There was a loss of body fat reflected by a significant decline in tricep (p=0.0003) and subscapular skinfold thickness SDS (p=0.0023). After 12 months, there was a significant rise in insulin (p=0.0052) and leptin levels (p=0.0048) and a significant decrease in resistin (p=0.0312) and TNF-α (p=0.0137). We observed that lipid and glucose metabolisms are only slightly affected in GHD children. Growth hormone replacement therapy affects some factors, such as leptin, resistin and fat mass, suggesting that also in children, GH treatment has a role in the regulation of factors secreted by adipose tissue.

“…Most clinical studies alluded that leptin augments the risk of cardiovascular events [6]. In a recent study, elevation of serum leptin has been reported in peripheral arterial occlusive disease caused by atherosclerosis [7].…”
