“…During the experimental trials, the experimental cows were reared in a closed dairy herd and divided into two groups according to the plasma BHBA concentration and other metabolic indicators of ketosis. The basis of cow inclusion criteria was: if the cows' plasma BHBA concentration was greater than 1.2 mM on one and more times out of six blood samples, they were designated as the SK group (He et al, 2018;, If the experimental Holstein cows' plasma BHBA concentrations were below 1.0 mM in six blood samples, they were assigned as the NK group in combination with paired parameters. Paired design was used in both experiments.…”

Ketosis is a major metabolic disorder that can lead to huge economic losses in postpartum dairy cows by influencing milk production and reproduction performance. Therefore, it is very important to understand the characteristics and significance of plasma GH levels and dynamic changes in postpartum dairy cows for finding pathogenesis of subclinical ketosis (SK). The present study aimed to determine the role of growth hormone (GH) from the onset of SK to the fifth week postpartum and to explain the variations in GH, and metabolic markers namely, β-hydroxybutyric acid (BHBA), non-esterified fatty acid (NEFA) and glucose (GLU) at early and later SK stages in postpartum Holstein cows. A 5-wk test and an intraday 12-h test were conducted in postpartum Holstein cows. Both tests were carried out every three hours from 10:00–22:00 for 7–14 days postpartum (12-h test: n = 16) to determine plasma concentrations of GH, BHBA, NEFA and GLU. The 5-wk test results showed that GH, BHBA and NEFA concentrations were significantly higher in the SK group during the five-weeks postpartum (p < 0.01); GLU concentration was significantly lower in the SK group (p < 0.01). Intraday 12-h test results revealed that the feeding time affected the plasma concentrations of GH, BHBA, NEFA and GLU. After 1-h of feeding time, GH concentrations decreased, while BHBA, NEFA and GLU concentrations increased. After 4-h of feeding time GH, BHBA and NEFA had the highest plasma concentrations, and GLU the lowest. In both experiments, GH was positively correlated with BHBA, NEFA, and negatively correlated with GLU. It can be suggested that GH has a potential role in development and aetiology of subclinical ketosis.

The Progress of Offshore CO₂ Capture and Storage

et al. 2021

With the development of the offshore oil and gas fields, more and more offshore oil and gas fields are found to have high carbon dioxide. In addition, as peaking carbon dioxide emissions and carbon neutrality were written into the government work report for the first time, the correct separation and emission of CO2 have become a key issue that needs to be solved by offshore oil and gas fields. In this paper, we studied two CO2 separation methods suitable for offshore platforms and the current status of CO2 offshore storage and application. Moreover, the development of offshore carbon dioxide storage application was investigated in detail, and the technical characteristics and application prospects of CO2-EOR and CO2 replacing combustible ice were analysed and discussed. This paper analyses the challenges and countermeasures of offshore CO2 storage from many aspects. It provides a theoretical reference for future CO2 treatment in offshore oil and gas fields.

In this study, it was aimed to investigate the correlations with leptin, ghrelin, irisin and insulin levels in the blood serum of cattle with subclinical ketosis. For this purpose, 10 healthy and 10 Holstein cattle with subclinical ketosis obtained from farms in Burdur region were used. A diagnosis of subclinical ketosis was made according to the Rothera test performed in milk, by performing a general clinical examination of the animals. Blood samples were taken from vena jugularis into tubes without anticoagulant. Serum leptin, ghrelin, irisin and insulin levels were measured in the obtained sera using commercial ELISA kits. In cows with subclinical ketosis, serum ghrelin, leptin, irisin and insulin values were increased compared to the control group (p
