Abstract
Logistics is an important sector that supports every sector of the economy, and thus, the development of nations is impossible without efficient logistics. Alongside this, the logistics sector generates various kinds of emissions that degrade the quality of the environment. Developed countries are striving to introduce green logistics to avoid environmental damages caused by transportation. Also, developing countries will start focusing on developing green logistics sooner or later. Keeping this in view, a comparative panel study on the group of seven (G7) and Emerging Seven (E7) nations is conducted to study the impacts of various economic and financial variables on green logistics. The data from 1996 to 2018 is analyzed using some reliable methods that produce efficient and consistent results during heterogeneity and cross-sectional dependence. The findings disclosed that cointegration is present in E7 and G7 panels. For E7 countries, the results disclosed that research and development (R&D), FDI, portfolio investment, and trade openness reduce green logistics. However, in the G7, R&D, FDI, portfolio investment, and trade increase green logistics. The empirical analysis did not show any meaningful impact of financial development and economic growth on green logistics in both groups of nations. Lastly, based on the comparative analysis, various policies are suggested for E7 to catch up with the G7 regarding logistics development. Also, policies for G7 are suggested to boost green logistics.

Abstract
The aim of this study was to determine the effect of exogenous GSH, an important antioxidant containing thiol group, on total antioxidant capacity (TAC) and total oxidant capacity (TOC), adenosine deaminase (ADA), a significant indicator of cellular immunity, and nitric oxide (NO) concentrations in rabbits. Sixteen healthy New Zealand rabbits were divided into 2 groups as control and GSH-treated group. Animals in control group received single intraperitoneal (ip) administration of 0.9% saline. Rabbits in GSH-treated group received reduced L-glutathione (10 mg/kg) (ip). Blood samples were taken from the marginal ear vein 0, 3, 6 and 12 hours after injection. Plasma TAC and NO levels were not statistically different between control and GSH group at 0 and 12 hours. Plasma TAC level was found to be significantly higher (p < 0.05) while NO level was found to be significantly lower (p < 0.05) in GSH treated group when compared to control group at 3 and 6 hours. Plasma TOC and ADA activity were not statistically different between control and GSH group during experiment. In conclusion, exogenous GSH resulted in an alteration of TAC and NO but not TOC and ADA, so exogenous GSH may be a valuable enhancer of the antioxidant system.

Abstract
Rasagiline (RSG) and selegiline (SEL) are potent selective monoamine oxidase-B inhibitors and used in the treatment of Parkinson's disease. Selegiline is metabolized in vivo to I-methamphetamine and I-amphetamine which effect cardiovascular system. Therefore, the aim of this study was to evaluate and to compare the effects of long-term use of these drugs on QT interval in conscious rabbits. The study involved 17 New Zealand rabbits of both sexes, aged between 7 and 14 months. Control group (CG, n = 6) was orally given isotonic saline solution at dose of 0.5 cc/per rabbit. The SEL group (SG, n = 6) received 5 mg/per rabbit SEL orally twice daily (09:00 am and 09:00 pm) for 14 days. The RSG group (RG, n = 5) was orally given of RSG at 1 mg/per rabbit daily for 14 days. Electrocardiographic records were taken before the experiment (baseline) and at 1st, 7th, and 14th days of experiment by direct writing electrocardiograph for two groups. Heart rate (HR), QT and QTc values were determined from ECG records. HR did not significantly differ in both treatment groups through the experimental period when compared to baseline values. The significant prolongation of QT and QTc values were observed at 7th, and 14th day (p < 0.01) in SG and 1st day of experiment in RG (p < 0.05) as compared to baseline values. In conclusion, the results obtained suggest a statistically significant effect of SEL on QTc prolongation when compared to RAS. QTc prolongations should be taken into account in Parkinson's disease where autonomic system is involved.

Abstract
Pregabalin (PRG) is a new antiepileptic drug that has been used as supportive therapy for partial seizures in patients. Although many neuro-psychiatric and non-cardiac drugs are known to prolong ventricular repolarization as manifested by QTc prolongation on ECG of which provokes torsades de pointes, there is limited data available regarding the characteristics of QT interval in conscious laboratory animals after PRG administration. For that purpose, effects of different therapeutic doses of oral PRG administration on Heart Rate (HR), QT and QTc values in rabbits were evaluated at a predefined time interval in this research. The study involved 28 New Zealand rabbits of both sexes, aged between 8 and 12 months. Animals were divided into four equal groups. Rabbits in control group (CG) received saline 0.5 ml/per animal orally. Group I, II and III were orally given single dose of PRG at 1.25 mg/kg, 2.5 mg/kg and 5 mg/kg, respectively. ECG records were taken before experiment (baseline) and at 1st, 2nd, 4th, and 6th hour (h) of experiment by direct writing electrocardiograph. HR, QT and QTc values were determined from ECG records. Heart rates increased in all groups when compared to baseline values. The increases were evident at 4th h in group II (p < 0.001), at 2nd h (p < 0.05) and 4th h (p < 0.001) in group III compared with CG. After application of PRG, QTc began to prolong at 1st h through the 4th of experiment and then turned to baseline values at 6th h of the experiment. The QTc values obtained at 2nd h in Group II and III (p < 0.05) and 4th h (p < 0.001) of application in group III were significantly different from CG. Changes obtained in HR, QT and QTc values in PRG treated rabbits were time and dose dependent (p < 0.001). Increase in HR and QTc prolongation determined in PRG given rabbits may implied that clinicians should take care of these changes when using this drug and further studies are required to fully understand the mechanism involved.

Abstract
The aim of this study was to evaluate changes in heart rate (HR), QT and RR intervals and corrected QT (QTc) values in conscious male and female New Zealand rabbits which intravenously received oxytocin (OXT) at different dosages. Animals were divided into 6 equal groups: group I (n = 6 male, received 0.75 U OXT per animal); group II (n = 6 male, received 1.5 U OXT per animal); group III (n = 6 male, received 3 U OXT per animal); group IV (n = 6 female, received 0.75 U OXT per animal); group V (n = 6 female, received 1.5 U OXT per animal); group VI (n = 6 female, received 3 U OXT per animal). ECG recording were taken from all animals before injection and then at 2, 4, 6, 8, 10, 15 and 20 min of OXT administration. QT and RR intervals obtained at 2 min of OXT administration were significantly prolonged in all groups (p < 0.05) with one exception that is the 1.5 U OXT injected female group where only QT interval did not change. The prolongation of QT and RR intervals persisted for 20 min in 1.5 U OXT injected male group while only QT interval prolongation was obvious for 20 min in 3 U OXT injected female group as for the other groups the prolonged interval were observed for 8-10 min and then returned to baseline values. Generally, a significant prolongation of QTc was noticed in both male and female rabbits at the 2 and 4 min in all groups and bradycardia was noticed at 2 min of OXT administration in all groups. Heart beats returned to normal values in all groups after 8 min of OXT administration. The change of HR, RR, QT and QTc was gender- but not dose-dependent (p < 0.001). The male rabbits were more sensitive to OXT effect then female rabbits. In conclusion, OXT used in therapeutic dosages decreased heart rate and prolonged QT and QTc intervals. Although cardiovascular effect of OXT are of short duration, its use in patient with risk factors for malignant arrhythmias requires more attention.

Abstract
The protective effect of L-carnitine was investigated against tilmicosin-induced cardiotoxic effects including blood creatine kinase (CK), CK-MB, total sialic acid as well as the alterations in glutathione and malondialdehyde concentrations in mice. Thirty-two Balb/C mice were divided into four groups including group 1 (control), group 2 (L-carnitine, s.c., 500 mg/kg for 5 days), group 3 (tilmicosin, s.c., single dose of 75 mg/kg) and group 4 (L-carnitine plus tilmicosin). Serum CK, CK-MB and malondialdehyde (MDA) levels were significantly (P < 0.05) higher in group 3 compared with those of other groups. Total sialic acid level in group 3 was found to be significantly (P < 0.05) higher than that in groups 1 and 2, as well. Contrary to these results, glutathione level in group 3 was found to be significantly (P < 0.05) lower than that in groups 1 and 2. In group 4, serum CK, CK-MB, MDA and total sialic acid levels were found to be significantly (P < 0.05) lower than those in group 3. These results suggest that tilmicosin is cardiotoxic in mice as evidenced by higher total sialic acid, CK and CK-MB. In addition, tilmicosin caused the decrease in glutathione and increase in MDA levels. However, administration of L-carnitine could ameliorate these adverse toxic effects of tilmicosin in mice.

Abstract
This study was designed to evaluate the effect of L-carnitine supplementation on the plasma malondialdehyde (MDA) and whole blood reduced glutathione (GSH) concentrations in experimentally-induced chronic aflatoxicosis in quails. For this purpose, a total of 80 quails up to 8 weeks old were divided into four equal groups. Group I served as control, Group II was given L-carnitine at the dose of 200 mg/litre in the drinking water for 60 days, Group III was given 60 microg total aflatoxin/kg diet for 60 days, and Group IV was given both 60 microg total aflatoxin/kg diet and 200 mg L-carnitine/litre in the drinking water for 60 days. Aflatoxin treatment caused a significant increase in plasma MDA and a significant decrease in blood GSH concentrations. On the other hand, there was a significant decrease in plasma MDA and a significant increase in whole blood GSH in the L-carnitine-supplemented group. The present study demonstrated that L-carnitine brought about the inhibition of lipid peroxidation by enhancing antioxidant capacity in quails with chronic aflatoxicosis.

Abstract
This study was designed to evaluate possible organ and system disorders associated with experimentally induced levamisole poisoning in dogs. For this purpose, twelve clinically healthy dogs of different ages, sexes and breeds were used. They were divided into two equal groups (Group A and Group B) and given levamisole orally at a dose of 25 mg/kg of body weight daily for three days. The dogs in Group B were also injected with atropin sulphate (0.04 mg/kg of body weight) subcutaneously (sc) 1 hour after each administration of levamisole. Routine clinical examinations were made and some haematological, biochemical and blood gas parameters were established at various times after administration of levamisole. The dogs in Group A developed severe neurological signs, gastric haemorrhage, bloody vomiting, colic, anaemia and four dogs died. In Group B these signs were mild and only one dog died. Levamisole poisoning was characterised by a significant reduction in the total number of red blood cells (RBCs), concentration of haemoglobin (Hb) and packed cell volume (PCV), and by anaemia. Peripheral blood pH, actual bicarbonate of plasma (HCO3), actual base excess (BE), partial pressure of oxygen (pO2) and saturated oxygen (O2SAT) increased in both groups of animals and these dogs developed metabolic alkalosis 48 hours after the first administration of levamisole. The results of the study also show that levamisole poisoning in dogs causes a significant increase in the activity of serum alanine aminotransferase (ALT) and of alkaline phosphatase (AP) and in the concentration of urea in both Group A and Group B. In the study, atropin sulphate reduced the severity of the clinical signs and the number of deaths, but it was not alone sufficient to remedy levamisole poisoning in dogs.

Abstract
Effects of L-carnitine administration via drinking water on growth performance, carcass traits, blood serum parameters and abdominal fatty acid composition of ducks was examined. One hundred day-old Turkish native duck chicks were divided into two groups, each with five replicates and given the same diets with 0 and 200 mg/l carnitine chlorhydrate via drinking water. The study lasted 8 weeks, with the first 4 weeks as a starter and the last 4 weeks as grower period. At the end of the study five ducks were randomly selected from each subgroup for slaughter. Growth performance parameters of ducks were not affected significantly by L-carnitine administration. Live weight, daily weight gain, cumulative feed consumption and average feed conversion efficiency were found to be 1490 and 1621 g, 26.0 and 28.1 g, 5386 and 5662 g, 3.75 and 3.54 kg/kg in the control and in the carnitine groups respectively. L-carnitine administration did not effect carcass traits and serum cholesterol, total lipid, triglyceride and glucose levels. Total saturated fatty acid content of abdominal fat significantly decreased, mono- and polyunsaturated fatty acid content were not affected by L-carnitine administration. In conclusion, L-carnitine administration by drinking water did not affect growth performance, carcass traits and blood parameters in ducks.
