The study was conducted to investigate the effects of different irrigation levels and nitrogen doses on yield, yield parameters, silage characteristics, digestibility, gas and methane production of corn silage. Three different irrigation levels (50%, 75% and 100% of depleted water) and 3 different nitrogen doses (100, 200 and 300 kg ha-1 N) were applied to corn silage. Experiments were implemented in split-split plots design with three replications during the growing seasons of 2013-2014. Plants were harvested at milk-dough stage and yield and morphologic characteristics were determined. Then, harvested plants were silaged and chemical characteristics were investigated. Irrigation level x nitrogen dose interaction was not found to be significant. Increasing nitrogen doses increased plant height, plant diameter, green herbage yield, crude protein, metabolic energy, gas production and organic matter digestibility and decreased pH levels, ADF and NDF ratios. Increased irrigation levels positively affected green herbage yield, plant height, plant diameter and increased ADF and NDF ratios. Gas production, metabolic energy and organic matter digestibility decreased with increasing irrigation levels. Increasing irrigation levels improved corn yields, but reduced the quality. On the other hand, increasing nitrogen doses had positive contributions both to yield and quality characteristics.

Objectives. This study is aimed at investigating alterations in liver volume during obstructive jaundice in rat liver. Materials and Methods. Thirty-six rats were divided into four groups. Abdominal tomography was performed for baseline volumetric analyses. The main bile ducts were ligated (BDL). Volumetric analyses were repeated 3 days after BDL in group 1, 7 days after BDL in group 2, 15 days after BDL in group 3, and 25 days after BDL in group 4, and total hepatectomy was performed in all animals. Control group (n = 4) was created with the rats that died before bile duct ligation. Results. There was no difference found in liver volume in group 1 compared to control animals. The liver volume was increased 7 days after BDL (P = 0.01). It was increased up to 60% of baseline values 25 days after BDL (P = 0.002). Wet liver weights of animals were also increased compared to control group. Liver weights were increased up to 40% percent of baseline values in group 4 (P = 0.002). Conclusions. Liver volume and weight were increased after BDL. Liver surgery in patients with huge liver mass is generally associated with significant difficulty. The surgeon should be aware of the time-dependent alteration in liver volume after obstructive jaundice.

SCUBE1 levels are a new biomarker that can be used in the differential diagnosis and monitoring of patients hospitalized with suspected CCHF. These levels are also significant as potential predictors of mortality.
