The results suggest that PJ consumption improves sperm quality and antioxidant activity of rats.

PurposeTo identify predictors of corporate financial distress, using the discriminant and logit models, in an emerging market over a period of economic turbulence and to reveal the comparative predictive and classification accuracies of the models in this different environmental setting.Design/methodology/approachThe research relies on a sample of 27 failed and 27 non‐failed manufacturing firms listed in the Istanbul Stock Exchange over the 1996‐2003 period, which includes a period of high economic growth (1996‐1999) followed by an economic crisis period (2000‐2002). The two well‐known methods, discriminant analysis and logit, are compared on the basis of a better overall fit and a higher percentage of correct classification under changing economic conditions. Furthermore, this research attempts to reveal the changes, if any, in the bankruptcy predictors, from those found in the earlier studies that rested on the data from the developed markets.FindingsThe logistic regression model is found to have higher classification power and predictive accuracy, over the four years prior to bankruptcy, than the discriminant model. In this research, the discriminant and logit models identify the same number of significant predictors out of the total variables analyzed, and six of these are common in both. EBITDA/total assets is the most important predictor of financial distress in both models. The logit model identifies operating profit margin and the proportion of trade credit within total claims ratios as the second and third most important predictors, respectively.Originality/valueThis paper reveals the accuracy with which the discriminant and logit models work in an emerging market over a period when firms face high uncertainty and turbulence. This study may be extended to other emerging markets to eliminate the limitation of the small sample size in this study and to further validate the use of these models in the developing countries. This can serve to make the methods important decision tools for managers and investors in these volatile markets.

Background: Increasing evidence-based indications for the implantation of permanent pacemakers (PMs) and implantable cardioverter defibrillators (ICDs) have led to an increase in the rate of device infections.The aim of the present study was to evaluate infection frequency, clinical characteristics, risk factors, and microbiologic and therapeutic features in patients with PM/ICD infections. Hypothesis: Clinical and demographic characteristics of the patients can affect the PM/ICD infections. Methods: The PM/ICD infection group consisted of 57 patients diagnosed and treated with PM/ICD infections in our hospital. The control group in this case-control study consisted of 833 patients in whom a PM or ICD had been implanted and no infections were noted. Results: Patients with PM/ICD infections (median age 65 years; range, 18-104 years) were older than those without PM/ICD infections (median age 58 years; range, 18-86 years; P = 0.005). The percentage of generator replacement was higher in the PM/ICD infection group compared with the control group (16% vs 8%, P = 0.003). Independent predictors of PM/ICD infections were advanced age (>60 years; odds ratio [OR]: 2.5, 95% confidence interval [CI]: 1.2-4.0, P = 0.021) and device revision (OR: 3.8, 95% CI: 1.5-5.5, P = 0.002). Primary antibiotic prophylaxis during the procedure reduced the risk for PM/ICD infection (OR: 0.5, 95% CI: 0.4-0.8, P = 0.011). Conclusions: PM/ICD infections occur in a significant number of patients. It is important to be aware of the risk factors for PM/ICD infections so that patients with an increased risk can be identified and preventive measures can be implemented.

Summary Objective:  This study was designed to determine the relationship between serum uric acid level and the presence and severity of coronary artery disease (CAD). Methods:  A total of 1012 patients who underwent coronary angiography were included in this study. All patients were assessed for the presence of cardiovascular risk factors and ongoing medications. Serum uric acid and creatinine level, as well as a fasting lipid profile and fasting blood glucose, were measured in all patients before the procedure. The severity of CAD was assessed by the Gensini score. Results:  Of 1012 patients (mean age, 59.4 ± 10.24 years), 680 were men (mean age, 58.7 ± 10.5 years) and 332 were women (mean age, 61.0 ± 9.51 years). Of the study patients, 703 (69%) were hypertensive, 292 (28.9%) were diabetic (DM), 304 (30%) had a smoking history, 306 (30%) had low high‐density lipoprotein cholesterol levels and 350 (34%) had hypertriglyceridaemia. CAD was present in 689 (68%) patients who were assessed by coronary angiography. One‐, two‐ and three‐vessel disease was detected in 32.6%, 32.5% and 34.9% of the patients respectively; left main coronary artery lesion was detected in 15% of the patients. A statistically significant difference in the mean uric acid concentrations was found between the patients with or without CAD [380 ± 121 μmol/l (6.39 ± 2.04 mg/dl) vs. 323.5 ± 83.2 μmol/l (5.44 ± 1.40 mg/dl) p < 0.001]. Based on logistic regression analysis, the increased serum uric acid level was found to be associated with the presence of CAD in both men and women (p < 0.001). The increased serum uric acid level was also found to be associated with the severity of CAD in both men and women based on multivariate linear regression analysis (p < 0.001). Conclusion:  In conclusion, serum uric acid level was found to be associated with the presence and severity of CAD.

This study was carried out to investigate the efficacy of PGF(2alpha) for oestrus synchronization (ES) in Awassi ewes to which were administered the progestagen-PMSG combination, and to evaluate the effect of the exogenous GnRH administration immediately after the artificial insemination (AI) on their pregnancy rate and lambing performance during the breeding season. The ewes (n = 33) were treated with an intravaginal sponge impregnated with 30 mg fluorogestane acetate for 12 days and were injected with 500 IU PMSG at the time of removal of the sponge. The ewes were then divided into three equal groups of 11 ewes each. One millilitre of physiological saline (0.9% NaCl; placebo) was administered to each ewe in Group 1 at the time of second AI. Approximately 4 microg GnRH (busereline) was injected to each ewe in Group 2 immediately after second AI. A total of 150 microg PGF(2alpha) (cloprostenole) was injected at the time of sponge removal on day 12 and 4 microg GnRH immediately after the second AI was also treated to each ewe in Group 3. Intracervical AI with diluted fresh semen was performed twice at 12 and 24 h following the onset of oestrus. The injection-oestrus onset and injection-oestrus-end interval in Group 3 was significantly (p < 0.001) shorter than both Groups 1 and 2. Although the pregnancy rates of Groups 2 and 3 (81.8%; 9/11) were numerically higher than of Group 1 (63.6%; 7/11), the difference among the groups was statistically insignificant. The multiple birth rate of Group 3 was found higher than Groups 1 and 2. However, the number of single lambs of Group 1 was also higher than Groups 2 and 3 (p < 0.05). Despite the litter sizes of Groups 2 (1.27; 14/11) and 3 (1.55; 17/11) being numerically higher than Group 1 (0.73; 8/11), the differences among all the groups were statistically insignificant. In conclusion, the administration of PGF(2alpha) at the time of removal of the sponge shortens the injection oestrus-onset and oestrus-end interval in Awassi ewes treated with progestagen-PMSG. Additionally, exogenous GnRH treatment immediately after the AI increases the multiple birth rate of Awassi ewes synchronized with progestagen-PMSG-PGF(2alpha) combination.

Prolonged SAPWD and Pd were determined to indicate electrical disturbances in the atrial myocardium, and predict the increase in the prevalence of SVA in patients with ASA.

The aim of this prospective clinical study is to evaluate the relationship between changes in functional cardiac parameters following anthracycline therapy and carbonyl reductase 3 (CBR3p.V244M) and glutathione S transferase Pi (GSTP1p.I105V) polymorphisms. Seventy patients with normal cardiac function and no history of cardiac disease scheduled to undergo anthracycline chemotherapy were included in the study. The patients' cardiac function was evaluated by gated blood pool scintigraphy and echocardiography before and after chemotherapy, as well as 1 year following therapy. Gene polymorphisms were genotyped in 70 patients using TaqMan probes, validated by DNA sequencing. A deteriorating trend was observed in both systolic and diastolic parameters from GG to AA in CBR3p.V244M polymorphism. Patients with G-allele carriers of GSTP1p.I105V polymorphism were common (60%), with significantly decreased PFR compared to patiens with AA genotype. Variants of CBR3 and GSTP1 enzymes may be associated with changes in short-term functional cardiac parameters.

Atrial septal aneurysm (ASA) is a saccular deformity located in the atrial septum. Atrial arrhythmias are common in patients with ASA. Atrial electromechanical delay (AEMD) can be used to evaluate development of atrial arrhythmias in various settings. The aim of the study was to investigate the relationship between ASA, cardiac arrhythmias and AEMD. Seventy patients with ASA served as the study group (30 men; mean age, 33.6 ± 10.9 years) and 70 healthy volunteers served as the control group (34 men; mean age, 31.4 ± 7.8 years). ASAs were diagnosed by transthoracic echocardiography based on the criteria of a minimal aneurysmal base of ≥ 15 mm; and an excursion of ≥ 10 mm. Inter-AEMD and intra-AEMDs of both atrium were measured from parameters of tissue Doppler imaging. There was no significant difference between the study and control groups in terms of age, gender, left atrium diameter, and left ventricular ejection fraction. Inter-AEMD (50.7 ± 22.5 ms vs. 36.9 ± 12.0 ms) and intra-left AEMD (44.6 ± 17.4 ms vs. 30.7 ± 11.6 ms) were significantly higher in patients with ASA with respect to control group. Inter-AEMD (63.6 ± 20.1 ms vs. 45.1 ± 21.5 ms, P = 0.001), intra-left AEMD (55.3 ± 15.6 ms vs. 40.1 ± 16.2 ms, P = 0.001), diameter of the ASA (19.9 ± 3.6 mm vs. 17.1 ± 2.7 mm, P = 0.001) and P wave dispersion (18.5 ± 6.7 ms vs. 11.8 ± 7.3 ms, P = 0.001) were significantly greater in the subgroup with arrhythmias compared to the subgroup without arrhythmias. Inter-AEMD and intra-left AEMD were found to be significantly prolonged in patients with ASA. Being a non-invasive, inexpensive and simple technique AEMD may provide significant contributions to assess the risk for paroxysmal supraventricular arrhythmia in patients with ASA.
