The aim of the present study is to assess the effects Fenugreek (Trigonella foenum-graecum, Fabaceae), sunflower (Helianthus annuus, Asteraceae), green cardamom (Elettaria cardamomum, Zingiberaceae) and seed extracts, which they belonged to three different plant families, on common carp (Cyprinus carpio L.) spermatozoa motility parameters and oxidative stress conditions. For this reason, sperm samples treated with seed extracts at the ratios of 0.1%, %0.5, 1%, and 2%, were incubated at 4°C and sampled at 2nd and 48th hours. Among sperm motility parameters, curvilinear velocity (VCL), average path velocity (VAP), straight-line velocity (VSL), straightness STR), linearity (LIN), and wobble (WOB) were determined by computer-assisted sperm analysis (CASA). According to the results, sunflower and green cardamom seed extracts have attenuated motility parameters at all tested concentrations. However, motility parameters measured in %0.5 of fenugreek seed extract were higher than all other groups including the control at 48th hour. Also, TBARS values as an oxidative stress indicator in this group were decreased. 2% of all seed extracts had negative effects on the sperm samples. Particularly, 2% sunflower seed extract caused the higher oxidative stress. These results indicate that fenugreek seed extract is more proper for the maintenance of common carp spermatozoa at 4°C, comparing to those of sunflower and green cardamom.

This study investigated the in vitro effects of different concentrations of Atrazine (0.001, 0.01, 0.1, 0.5 mg/L) added to motile and immotile solutions on kinematics quality of sperm cells of common carp, Cyprinus carpio, which is a fish of economic significance. The kinematics of the sperm cells was analyzed by a computer-assisted sperm analysis system (CASA). As a result of the study, while there was a significant difference (P < 0.05) between the groups in terms of the VSL (μm/s) and VCL (μm/s) values after the Atrazine-added immotile solution’s (IMS) and incubation for 3 hours, there was a significant difference (P < 0.05) in only the VSL values directly activated by the Atrazine-added motile solution (MS). DNA fragmentation was evident but not in higher numbers in the 0.1 mg/L atrazine group. Finally, it was determined the effective concentration (EC50) values of the VSL value of the motile and immotile solution as 0.34 mg/L and 0.03 mg/L, respectively.

The purpose of the current study was to analyze phenotypic and functional characteristics of common carp (Cyprinus carpio) spermatozoa during in vitro aging and to investigate whether global DNA methylation is affected by sperm aging. Milt was collected from five individual males, stored in vitro on ice in a refrigerator for up to 96 h post stripping (HPS) and used to fertilize eggs with intervals of 1, 24 and 96 h. Computer-assisted sperm analysis and a S3e Cell Sorter was employed to determine the spermatozoa phenotypic characteristics (motility, velocity, concentration and viability). In addition, pH and osmolality of the seminal fluid and the capacity of the spermatozoa to fertilize, hatching rate and health of the resulting embryos were examined at different aging times. Whole-genome bisulfite sequencing was used to compare the global and gene-specific DNA methylation in fresh and aged spermatozoa. The results demonstrated that spermatozoa aging in common carp significantly affects their performance and thus the success of artificial fertilization. The methylation level at the cytosine-phosphate-guanine (CpG) sites increased significantly with 24 HPS spermatozoa compared to the fresh group at 1 HPS and then decreased significantly at 96 HPS. A more detailed investigation of gene specific differences in the DNA methylation was hindered by incomplete annotation of the C. carpio genome in the public databases.

The effect of taurine on the turkey spermatozoa motility and viability during the in vitro incubation was assessed. Experimental samples were prepared by diluting the raw semen in nine different concentrations of taurine – from 10 mg/ml to 0.078125 mg/ml. The motility parameters were evaluated by the CASA system (Computer Assisted Semen Analyser) using the program Sperm Vision<sup>®</sup> and for spermatozoa viability assessment the eosin-nigrosin staining was performed. Selected parameters were evaluated at six time periods: 0, 1, 2, 3, 4, and 5 h at 5°C and 41°C. At 5°C, a significantly lower percentage of motility and progressive motility was detected only in the samples with the highest concentration of taurine (10 mg/ml) at time 0 and 1. After 2 h of incubation a significant preventive effect of taurine on spermatozoa parameters was observed. The tendency of the taurine effect on motility parameters was different during the in vitro incubation at 41°C. Significantly lower values of motility parameters were detected in all experimental samples in comparison to the control after 5 h. The analysed concentrations of taurine did not significantly affect viability of turkey spermatozoa during all time periods. A higher percentage of dead spermatozoa were observed at 41°C (4.87–9.90%) if compared to 5°C (2.12–4.88%). The results indicated that the addition of taurine (from 2.5 to 7.5 mg/ml) to turkey spermatozoa positively affected the monitored spermatozoa parameters incubated at 5°C.

Root-knot nematodes, Meloidogyne spp., are the major nematode pests of economic crops worldwide. Use of conventional nematicides has been one of the most effective methods to reduce their populations. However, the ban on many effective nematicides in recent past has necessitated the search for alternative sources of effective and ecofriendly chemicals for nematode control. The nematicidal potential of fifteen Leguminosae seeds (wild and cultivated) was assessed, in vitro, against juveniles of Meloidogyne incognita (Kofoid & White) Chitwood. Each standard aqueous seed extract, 25g/100ml (w/v), was evaluated at dilutions, 1:10, 1:20, and 1:40 at 27+1�C for 24 hours. The majority of seed extracts caused high mortality rates, especially in 1:10 concentration. Trigonella foenum graceum, Sesbania sesban, Albizzia lebbak, Cassia fistula and Pongamia glabra were the most efficacious (above 90% mortality). S. sesban and P. glabra were significantly effective even in the lowest concentration (1:40).
