Two experiments were conducted to determine the effects of different methionine (Met) sources regarding their absorption kinetics and utilisation in female single-meal-fed broiler chickens. 2. A total of 340, one day old female Ross 308 broiler chickens were fed commercial starter and grower diets for 38 d. Birds were then allocated to treatment diets in two experiments as a completely randomised design with four replicates of five chicks per each until 60 d of age. In experiment 1, a 2 × 5 factorial design was used to investigate the effect of two sources (DL-Met and AQUAVI®Met-Met) and five equimolar levels (0.4, 0.8, 1.2, 1.6, and 2 g/kg) in the diet. In experiment 2, different proportions of protein-bound methionine (PB-Met) to DL-Met (0.4:1.6, 0.8:1.2, 1.2:0.8: 1.6:0.4, and 2:0 g/kg) were incorporated into a basal diet deficient in Met. During the experiment, chickens received 90 g of pelleted feed for a time period of 17 ± 2.5 min, once daily. 3. The results indicated that chickens fed diets supplemented with DL-Met and Met-Met showed a rapid rise in plasma Met 1 h after feeding, with a sudden drop at 2 h after feeding. In contrast, chickens fed PB-Met substituted diets showed a gradual plasma peak at 1 and 2 h postprandial (P < 0.01). Plasma homocysteine (HCY) content increased to 34.38 and 40.43 μmol/l with DL-Met2.0 and Met-Met2.0 diets, while it decreased to 25.68 μmol/l with PB-Met2.0(P ≤ 0.01). Chickens that received the PB-Met2.0 diet had higher (P ≤ 0.01) protein utilisation (0.54 g/g) and lower excreta nitrogen content (4.04 g/100 g excreta), which demonstrated the benefits of feeding a protein-bound Met source. The efficiency of Met utilisation was 0.69 g/g in chickens fed PB-Met2.0 diet, but only 0.36 and 0.41 g/g in those fed DL-Met2.0 and Met-Met2.0 (P ≤ 0.01). 4. The observed utilisation coefficient of DL-Met and Met-Met for single-meal meat-type chickens was lower than expected. The synchronisation of intestinal Met absorption maintained the efficiency of utilisation, which was related to the sources of added Met, with protein-bound Met showing the best utilisation and least excretion.

Pioglitazone has been proposed as a potential feed additive to reduce insulin resistance and consequently some of the metabolic disorders in transition cows. This study was aimed at determining the pharmacokinetic parameters of pioglitazone following oral administration (PO) or intravenous (IV) injection. Six lactating Holstein cows were randomly assigned into two groups (n=3 cows per group) in a crossover design, and administered with pioglitazone (8 mg/kg BW) either per-oral (PO) or intravenously (IV), with an 8-day washout period. Blood samples were collected from the jugular vein before and up to 48 h after pioglitazone administration. Plasma pioglitazone concentration was determined by HPLC. The data were analyzed using a non-compartmental model for PO route, and a two-compartmental model for the IV route. The bioavailability of PO-administered pioglitazone was 58% and the highest plasma concentration (C max), the time (t max) at which the drug reached C max , half-life (t 1/2), absorption rate constant (k ab) and elimination rate constant (k el) were 11.57±1.44 µg/mL, 5.67±0.07 h, 7.10±0.32 h, 0.28±0.09 h-1 and 0.10±0.013 h-1 , respectively. Elimination half-life (t 1/2β), volume distribution (V ss) and elimination rate constant (k el) after IV injection were 5.10±0.62 h, 0.12±0.01 L/kg and 0.47±0.06 h-1 , respectively. Because of the relatively high bioavailability and half-life, pioglitazone may be useful for oral administration as an insulin-sensitizing agent in dairy cows.

There are some of organic contaminants with low solubility in water. In order to improve the efficiency of remediation it is possible to use appropriate surfactants as flushing solution. In this work non-ionic (Poloxamer 407 and Tween 80), anionic (sodium dodecyl sulfate, SDS) and humic acid (HA) with solution of 0.1 M NaOH were selected for improving the remediation of a soil contaminated with anthracene. The solution of NaOH and surfactants were used as anolyte but humic acid was mixed with contaminated soil. At the end of each test a number of soil samples were extracted from the middle of the soil at different distances from the anode and the removal of contaminant was measured by a HPLC (High Performance Liquid Chromatography) apparatus. The results show that the effectiveness of solution surfactants and NaOH in removal of anthracene was SDS>Tween 80> Poloxamer 407. In addition, the results indicate that effect of humic acid on remediation is less than SDS and more than non-ionic surfactants.

The present study was undertaken to determine the effects of arginine, soy isoflavone (ISF) and hydroxypropylmethylcellulose (HPMC) on obesity in broiler breeder hens. 2. A total of 320 Cobb 500 hens, 45 weeks of age, were assigned to 64 floor pens. The experiment was conducted as a completely randomised design in a factorial arrangement (2 × 2 × 2 × 2) with 4 replicates of 5 hens in each pen. Factors included two concentrations of HPMC (0 and 1%), two concentrations of arginine (8.4 and 12 g/kg), two concentrations of ISF (zero and three times more than that present in basal diets) and two contents of energy (11.7 and 14.6 MJ/kg). Performance criteria and blood characteristics of hens were measured during the experimental period. Expression of genes involved in lipid metabolism was determined in the liver at 55 weeks of age. 3. Hens given high-energy diets showed increased BW (body weight), ovary weight and abdominal fat pad and enhanced plasma glucose, triglyceride (TG), cholesterol, haemoglobin, haematocrit and low lymphocyte percentages. The expression of malic enzyme, peroxisome proliferator-activated receptor-α (PPARα), peroxisome proliferator-activated receptor-γ (PPARγ) and inducible nitric oxide (iNOS) increased and sterol regulatory element binding protein-1c (SREBP1c) decreased with increasing energy content of diets. Arginine addition decreased TG, cholesterol and A1-c haemoglobin concentration and increased PPARα, PPARγ and iNOS expression. Inclusion of ISF and HPMC decreased BW, egg weight, plasma TG, cholesterol and increased egg production and also enhanced PPARγ and iNOS expression. Significant interactions were observed between energy concentration and ISF and HPMC on BW. 4. The results of the current study revealed that ISF, HPMC and arginine have beneficial effects on controlling the metabolism of obese broiler breeder hens and using a mix of these products minimises the harmful effects of obesity.

A series of experimental tests were carried out on contaminated soil in an electro-osmotic apparatus at different applied gradients of voltage and time. The tests were conducted with distilled water and ethylenediaminetetra acetic acid (EDTA) solution as electrolyte. During each test the values of pH at anode and cathode reservoirs and also the discharge from cathode were measured. At the end of each test a number of soil samples were extracted from the middle of the soil at different distances from the anode and the removal of contaminant was measured by a gas chromatography apparatus. The results indicate that with EDTA as electrolyte the highest efficiency for removal of MTBE is achieved with 2.0 V/cm gradient and in the duration of 14 days. In addition, EDTA causes the values of pH to increase and decrease in the cathode and anode reservoirs, respectively. It also decreases the effluent and electro-osmotic permeability in comparison with distilled water. Experimental data were analysed by ANOVA and t-test methods. These statistical analyses showed significant difference (at 5% level) between the reference and other tests.

Abstract Two new Hg(II) complexes of 4-pyridinecarbacylamidophosphate ligands, HgCl2(L1)2 C1 (L1 ... more Abstract Two new Hg(II) complexes of 4-pyridinecarbacylamidophosphate ligands, HgCl2(L1)2 C1 (L1 = 4-NC5H4C(O)NHP(O)[NHC(CH3)3]2); [Hg(L2)Cl3]−[(L2)H]+ C2 (L2 = 4-NC5H4C(O)NHP(O)[NHC5H9]2) were synthesized and characterized on the basis of elemental analysis, IR, UV–Vis, and multinuclear NMR spectroscopy. Molecular structures of C1 and C2 were determined by X-ray crystallography and revealed that coordination of ligands to Hg(II) has occurred from the nitrogen atom of the pyridine ring in neutral (C1) and ionic (C2) metal complexes. Coordination of L1 and L2 from Npyridine, as a monodentate ligand, resulted in infinite 1D and 2D hydrogen-bonded polymeric chains for C1 and C2, respectively. Mass spectral data further support the structure of the compounds and XRD indicates the crystalline state of metal complexes. The intermolecular hydrogen bonding interactions which connected the chains into 3D frameworks in both complexes were supported by Hirshfeld surface analysis and fingerprint plots. Also, natural bond orbital analysis divulges that the metal–ligand interaction in C1 and C2 is the LMCT. By using parameters derived from the quantum theory of atoms in molecules, the nature of Hg-ligand interaction is found to be mainly electrostatic with a small amount of covalent character. Hg(II) complexes and the corresponding ligands were also screened for their antibacterial activity against the selected Gram-positive and Gram-negative bacteria. Results indicated that C2 possess strong cytotoxic activity against the tested bacteria with MIC values ranging from 2.79 to 22.32 µg/ml. The activity of compounds was interpreted by their calculated descriptors, density, log P, and the lower unoccupied molecular orbital.

Samples were prepared of uncontaminated and contaminated soil-cement with 20 and 30% cement. Unconfined compression tests (UCT) were conducted on the natural soil and soil contaminated with anthracene. In addition, similar tests were carried out on uncontaminated and contaminated soil-cement at different curing times. Leaching tests were also conducted on contaminated soil and contaminated soil-cement with 20 and 30% cement at different curing times by using HPLC (High Performance Liquid Chromatography) apparatus. The results show that adding cement to contaminated soil increases the strength of the soil and the amount of increase in strength is a function of percent of cement and curing time. The results of the leaching tests on the contaminated soil show a major reduction in concentration of anthracene. The results also indicate that adding cement to the anthracene-contaminated soil causes a reduction in the concentration of anthracene after leaching tests and the amount of reduction is increased with increasing the curing time for a given cement content (20 or 30%). Increasing the percent of cement is an important factor in the reduction of concentration of anthracene.

The crystal structures of the C1 and C2 complexes were determined by single crystal X-ray diffraction techniques. X-ray crystallography analysis revealed that C1 and C2 are crystallized in the monoclinic C2/c and P21/n space groups, respectively. The results indicated that these similar ligands have different coordination patterns. Ligand L1 acts as a bidentate bridging ligand via the oxygen atom of the phosphoryl group and the nitrogen atom of the pyridine cycle between two Mn(II), while ligand L2 coordinates to Mn(II) via the nitrogen atom of the pyridine cycle. Quantum chemical studies were also performed to interpret two different coordination behavior of the ligands, using B3LYP/def2-TZVP level of theory.

The samples were prepared in two stages. In the first stage they were prepared with 20 and 30% cement but in the second stage they were prepared with 20 and 30% mixtures of bentonite and cement (with ratios of bentonite to cement equal to 1:1 and 3:1). Unconfined compression tests (UCT) and leaching tests using GC (Gas Chromatography) apparatus were conducted on the samples that were prepared in the above two stages at different curing times. The results show that by using cement, the strength of the soil is increased. The results of the leaching tests on contaminated soil show a major reduction in the concentration of MTBE. Adding cement to contaminated soil causes reduction in concentration of MTBE but by increasing the curing time the concentration of MTBE is increased. It is also indicted that using combination of bentonite and cement leads to reduction in MTBE concentration and the amount of reduction is decreased by increasing the curing time. The bentonite-cement ratio of 3:1 is more effective than 1:1 in reducing the concentration of MTBE.

Two experiments were conducted to determine the effects of different methionine (Met) sources regarding their absorption kinetics and utilisation in female single-meal-fed broiler chickens. 2. A total of 340, one day old female Ross 308 broiler chickens were fed commercial starter and grower diets for 38 d. Birds were then allocated to treatment diets in two experiments as a completely randomised design with four replicates of five chicks per each until 60 d of age. In experiment 1, a 2 × 5 factorial design was used to investigate the effect of two sources (DL-Met and AQUAVI®Met-Met) and five equimolar levels (0.4, 0.8, 1.2, 1.6, and 2 g/kg) in the diet. In experiment 2, different proportions of protein-bound methionine (PB-Met) to DL-Met (0.4:1.6, 0.8:1.2, 1.2:0.8: 1.6:0.4, and 2:0 g/kg) were incorporated into a basal diet deficient in Met. During the experiment, chickens received 90 g of pelleted feed for a time period of 17 ± 2.5 min, once daily. 3. The results indicated that chickens fed diets supplemented with DL-Met and Met-Met showed a rapid rise in plasma Met 1 h after feeding, with a sudden drop at 2 h after feeding. In contrast, chickens fed PB-Met substituted diets showed a gradual plasma peak at 1 and 2 h postprandial (P < 0.01). Plasma homocysteine (HCY) content increased to 34.38 and 40.43 μmol/l with DL-Met2.0 and Met-Met2.0 diets, while it decreased to 25.68 μmol/l with PB-Met2.0(P ≤ 0.01). Chickens that received the PB-Met2.0 diet had higher (P ≤ 0.01) protein utilisation (0.54 g/g) and lower excreta nitrogen content (4.04 g/100 g excreta), which demonstrated the benefits of feeding a protein-bound Met source. The efficiency of Met utilisation was 0.69 g/g in chickens fed PB-Met2.0 diet, but only 0.36 and 0.41 g/g in those fed DL-Met2.0 and Met-Met2.0 (P ≤ 0.01). 4. The observed utilisation coefficient of DL-Met and Met-Met for single-meal meat-type chickens was lower than expected. The synchronisation of intestinal Met absorption maintained the efficiency of utilisation, which was related to the sources of added Met, with protein-bound Met showing the best utilisation and least excretion.

The bioavailability of PO-administered pioglitazone was 58% and the highest plasma concentration (C max), the time (t max) at which the drug reached C max , half-life (t 1/2), absorption rate constant (k ab) and elimination rate constant (k el) were 11.57±1.44 µg/mL, 5.67±0.07 h, 7.10±0.32 h, 0.28±0.09 h-1 and 0.10±0.013 h-1 , respectively. Elimination half-life (t 1/2β), volume distribution (V ss) and elimination rate constant (k el) after IV injection were 5.10±0.62 h, 0.12±0.01 L/kg and 0.47±0.06 h-1 , respectively. Because of the relatively high bioavailability and half-life, pioglitazone may be useful for oral administration as an insulin-sensitizing agent in dairy cows.

There are some of organic contaminants with low solubility in water. In order to improve the efficiency of remediation it is possible to use appropriate surfactants as flushing solution. In this work non-ionic (Poloxamer 407 and Tween 80), anionic (sodium dodecyl sulfate, SDS) and humic acid (HA) with solution of 0.1 M NaOH were selected for improving the remediation of a soil contaminated with anthracene. The solution of NaOH and surfactants were used as anolyte but humic acid was mixed with contaminated soil. At the end of each test a number of soil samples were extracted from the middle of the soil at different distances from the anode and the removal of contaminant was measured by a HPLC (High Performance Liquid Chromatography) apparatus. The results show that the effectiveness of solution surfactants and NaOH in removal of anthracene was SDS>Tween 80> Poloxamer 407. In addition, the results indicate that effect of humic acid on remediation is less than SDS and more than non-ionic surfactants.

The present study was undertaken to determine the effects of arginine, soy isoflavone (ISF) and hydroxypropylmethylcellulose (HPMC) on obesity in broiler breeder hens. 2. A total of 320 Cobb 500 hens, 45 weeks of age, were assigned to 64 floor pens. The experiment was conducted as a completely randomised design in a factorial arrangement (2 × 2 × 2 × 2) with 4 replicates of 5 hens in each pen. Factors included two concentrations of HPMC (0 and 1%), two concentrations of arginine (8.4 and 12 g/kg), two concentrations of ISF (zero and three times more than that present in basal diets) and two contents of energy (11.7 and 14.6 MJ/kg). Performance criteria and blood characteristics of hens were measured during the experimental period. Expression of genes involved in lipid metabolism was determined in the liver at 55 weeks of age. 3. Hens given high-energy diets showed increased BW (body weight), ovary weight and abdominal fat pad and enhanced plasma glucose, triglyceride (TG), cholesterol, haemoglobin, haematocrit and low lymphocyte percentages. The expression of malic enzyme, peroxisome proliferator-activated receptor-α (PPARα), peroxisome proliferator-activated receptor-γ (PPARγ) and inducible nitric oxide (iNOS) increased and sterol regulatory element binding protein-1c (SREBP1c) decreased with increasing energy content of diets. Arginine addition decreased TG, cholesterol and A1-c haemoglobin concentration and increased PPARα, PPARγ and iNOS expression. Inclusion of ISF and HPMC decreased BW, egg weight, plasma TG, cholesterol and increased egg production and also enhanced PPARγ and iNOS expression. Significant interactions were observed between energy concentration and ISF and HPMC on BW. 4. The results of the current study revealed that ISF, HPMC and arginine have beneficial effects on controlling the metabolism of obese broiler breeder hens and using a mix of these products minimises the harmful effects of obesity.

A series of experimental tests were carried out on contaminated soil in an electro-osmotic apparatus at different applied gradients of voltage and time. The tests were conducted with distilled water and ethylenediaminetetra acetic acid (EDTA) solution as electrolyte. During each test the values of pH at anode and cathode reservoirs and also the discharge from cathode were measured. At the end of each test a number of soil samples were extracted from the middle of the soil at different distances from the anode and the removal of contaminant was measured by a gas chromatography apparatus. The results indicate that with EDTA as electrolyte the highest efficiency for removal of MTBE is achieved with 2.0 V/cm gradient and in the duration of 14 days. In addition, EDTA causes the values of pH to increase and decrease in the cathode and anode reservoirs, respectively. It also decreases the effluent and electro-osmotic permeability in comparison with distilled water. Experimental data were analysed by ANOVA and t-test methods. These statistical analyses showed significant difference (at 5% level) between the reference and other tests.

It is essential due to having leonurine with blood dilution and muscle relaxation effects. Research method: To evaluate the response of the Iranian Motherwort ecotypes in drought environments, an experiment was carried out in split plot design based on RCBD with three replications. Three irrigation levels were considered as main plots, including %100, one-third, and two-third of field capacity, and four ecotypes as sub-plots including Kerman, Taleghan, Sarab and Khansar. The experiment was conducted at Horticultural Research Station, the University of Tehran, in Karaj. Findings: The results showed that water stress affected morphological traits significantly. Water stress had a significant increasing effect on the phenolic and flavonoid contents and antioxidant activity of Motherwort ecotypes. The highest and the lowest total phenol content were ob...

Abstract Two new Hg(II) complexes of 4-pyridinecarbacylamidophosphate ligands, HgCl2(L1)2 C1 (L1 ... more Abstract Two new Hg(II) complexes of 4-pyridinecarbacylamidophosphate ligands, HgCl2(L1)2 C1 (L1 = 4-NC5H4C(O)NHP(O)[NHC(CH3)3]2); [Hg(L2)Cl3]−[(L2)H]+ C2 (L2 = 4-NC5H4C(O)NHP(O)[NHC5H9]2) were synthesized and characterized on the basis of elemental analysis, IR, UV–Vis, and multinuclear NMR spectroscopy. Molecular structures of C1 and C2 were determined by X-ray crystallography and revealed that coordination of ligands to Hg(II) has occurred from the nitrogen atom of the pyridine ring in neutral (C1) and ionic (C2) metal complexes. Coordination of L1 and L2 from Npyridine, as a monodentate ligand, resulted in infinite 1D and 2D hydrogen-bonded polymeric chains for C1 and C2, respectively. Mass spectral data further support the structure of the compounds and XRD indicates the crystalline state of metal complexes. The intermolecular hydrogen bonding interactions which connected the chains into 3D frameworks in both complexes were supported by Hirshfeld surface analysis and fingerprint plots. Also, natural bond orbital analysis divulges that the metal–ligand interaction in C1 and C2 is the LMCT. By using parameters derived from the quantum theory of atoms in molecules, the nature of Hg-ligand interaction is found to be mainly electrostatic with a small amount of covalent character. Hg(II) complexes and the corresponding ligands were also screened for their antibacterial activity against the selected Gram-positive and Gram-negative bacteria. Results indicated that C2 possess strong cytotoxic activity against the tested bacteria with MIC values ranging from 2.79 to 22.32 µg/ml. The activity of compounds was interpreted by their calculated descriptors, density, log P, and the lower unoccupied molecular orbital.

Samples were prepared of uncontaminated and contaminated soil-cement with 20 and 30% cement. Unconfined compression tests (UCT) were conducted on the natural soil and soil contaminated with anthracene. In addition, similar tests were carried out on uncontaminated and contaminated soil-cement at different curing times. Leaching tests were also conducted on contaminated soil and contaminated soil-cement with 20 and 30% cement at different curing times by using HPLC (High Performance Liquid Chromatography) apparatus. The results show that adding cement to contaminated soil increases the strength of the soil and the amount of increase in strength is a function of percent of cement and curing time. The results of the leaching tests on the contaminated soil show a major reduction in concentration of anthracene. The results also indicate that adding cement to the anthracene-contaminated soil causes a reduction in the concentration of anthracene after leaching tests and the amount of reduction is increased with increasing the curing time for a given cement content (20 or 30%). Increasing the percent of cement is an important factor in the reduction of concentration of anthracene.

The crystal structures of the C1 and C2 complexes were determined by single crystal X-ray diffraction techniques. X-ray crystallography analysis revealed that C1 and C2 are crystallized in the monoclinic C2/c and P21/n space groups, respectively. The results indicated that these similar ligands have different coordination patterns. Ligand L1 acts as a bidentate bridging ligand via the oxygen atom of the phosphoryl group and the nitrogen atom of the pyridine cycle between two Mn(II), while ligand L2 coordinates to Mn(II) via the nitrogen atom of the pyridine cycle. Quantum chemical studies were also performed to interpret two different coordination behavior of the ligands, using B3LYP/def2-TZVP level of theory.

The samples were prepared in two stages. In the first stage they were prepared with 20 and 30% cement but in the second stage they were prepared with 20 and 30% mixtures of bentonite and cement (with ratios of bentonite to cement equal to 1:1 and 3:1). Unconfined compression tests (UCT) and leaching tests using GC (Gas Chromatography) apparatus were conducted on the samples that were prepared in the above two stages at different curing times. The results show that by using cement, the strength of the soil is increased. The results of the leaching tests on contaminated soil show a major reduction in the concentration of MTBE. Adding cement to contaminated soil causes reduction in concentration of MTBE but by increasing the curing time the concentration of MTBE is increased. It is also indicted that using combination of bentonite and cement leads to reduction in MTBE concentration and the amount of reduction is decreased by increasing the curing time. The bentonite-cement ratio of 3:1 is more effective than 1:1 in reducing the concentration of MTBE.
