Effect of Glutathione-Supplemented INRA82 Extender on Miniature Caspian Stallion Sperm Quality during Storage at 5°C     

Mahdi Zhandi  Vahid Ghadimi  MSc 《Journal of Equine Veterinary Science》2014

This study was conducted to investigate the effect of glutathione-supplemented INRA82 extender on miniature Caspian stallion sperm quality during storage at 5°C. A total of 12 ejaculates from three stallions (four ejaculates from each stallion) were collected and diluted with INRA82 extender that included different concentrations of glutathione (0 [INRA-G0], 5 [INRA-G5], and 10 mM [INRA-G10]) and stored for 48 hours at 5°C. Sperm motility (computer-assisted sperm analysis), plasma membrane integrity (eosin–nigrosin staining) and functionality (hypo-osmotic swelling test), and malondialdehyde (MDA) level were determined during storage at 5°C. The results showed that the sperm total and progressive motility and plasma membrane integrity and functionality in all extenders were significantly decreased with increasing storage time. However, the MDA level in all extenders was significantly increased with increasing storage time. Also, the results showed that most of the evaluated sperm quality parameters in the present study, with the exception of MDA, were significantly greater in INRA-G5 than in INRA-G0 and INRA-G10 after 24 and 48 hours of storage at 5°C. We have concluded that supplementation of INRA82 with 5 mM glutathione can improve miniature Caspian stallion sperm quality during storage at 5°C by increasing total and progressive motility, plasma membrane integrity and functionality, and decreasing the MDA level compared with INRA-G0 and INRA-G10. More advanced in vitro evaluations and artificial insemination are required to reveal the exact effects of INRA-G5 on miniature Caspian stallion sperm quality and its fertilizing ability.  相似文献

Structure and molecular mechanism of a nucleobase-cation-symport-1 family transporter

The nucleobase-cation-symport-1 (NCS1) transporters are essential components of salvage pathways for nucleobases and related metabolites. Here, we report the 2.85-angstrom resolution structure of the NCS1 benzyl-hydantoin transporter, Mhp1, from Microbacterium liquefaciens. Mhp1 contains 12 transmembrane helices, 10 of which are arranged in two inverted repeats of five helices. The structures of the outward-facing open and substrate-bound occluded conformations were solved, showing how the outward-facing cavity closes upon binding of substrate. Comparisons with the leucine transporter LeuT(Aa) and the galactose transporter vSGLT reveal that the outward- and inward-facing cavities are symmetrically arranged on opposite sides of the membrane. The reciprocal opening and closing of these cavities is synchronized by the inverted repeat helices 3 and 8, providing the structural basis of the alternating access model for membrane transport.  相似文献   

Effect of nitrogen fixation,nitrogen fertilization and viral infection on yield,tannin and protein contents and in vitro protein digestibility of faba bean

A field investigation of two faba bean cultivars (cv.), Agabat and Silaim, showed that bean yellow mosaic virus (BYMV) infection reduced (p≤0.001) yield (Kg/ha), protein content and in vitro protein digestibility (IVPD) but increased (p≤0.05) tannin content (mg/100 ml). Nitrogen fertilization with viral infection significantly reduced yield and IVPD for cv. Silaim and increased (p≤0.05) protein and tannin contents. Nitrogen fertilization alone was found to increase (p≤0.05) yield, protein and tannin contents but slightly reduced IVPD.Rhizobium inoculation with viral infection significantly decreased yield per unit area, protein content and IVPD, but increased (p≤0.05) tannin content.Rhizobium inoculation alone significantly increased (p≤0.001) yield and tannin content and slightly increased protein content but decreased IVPD. The results indicated that nitrogen fertilization or nitrogen fixation increased yield, protein and tannin contents and decreased IVPD. Viral infection had an adverse effect on yield, protein content and IVPD but had no effect on tannin content.  相似文献   

Comparative therapeutic effect of moxidectin,doramectin and ivermectin on psoroptes mites infestation in buffalo (<Emphasis Type="Italic">Bubalus bubalis</Emphasis>)     

Sabry A. El-Khodery  Mitsu Ishii  Salama A. Osman  Magdy H. Al-Gaabary 《Tropical animal health and production》2009,41(7):1505-1511

The aim of the present study was to carry out comparative therapeutic effect of moxidectin pour on, doramectin and ivermectin on psoroptes infestation in buffalo. A total of 318 buffalo in 77 small scale herds suspected to have mange mites were examined clinically and parasitologically. Fifty-three (16.66%) buffalo in 25 herds were recorded to be infested; 51 (16.35%) with psoroptic mites, and two (0.31%) with chorioptic mites. Buffalo with psoroptic mites were randomly allocated into three groups (17 buffalo each). First group was treated with moxidectin pour on at a dose rate of 0.5 mg kg^-1. The second group received doramectin (200 μg kg^-1 twice subcutaneously, 14 days apart). The third group received ivermectin (200 μg kg^-1 twice subcutaneously, 14 days apart). Adjunct to each drug, deltamethrin was applied to the surrounding environment twice at a two week interval. Treatment outcomes of 51 buffalo with psoroptic mites showed that moxidectin pour on and doramectin had a significant higher effect on mite count reduction (MANOVA, P < 0.01; Walks^, Lambda, P < 0.01) and clinical sum scores (MANOVA, P < 0.05; Walks^, Lambda, P < 0.05) compared with injectible ivermectin. On clinical level, the number of clinically recovered buffalo in moxidectin and doramectin treated groups was significantly (P < 0.05) higher than that of ivermectin treated group. The result of the present study indicated that psoroptic mites are the main cause of mange in buffalo in Lower Egypt. This is the first report that describes the effect of moxidectin in buffalo. Moxidectin is a good alternative and easily applied drug for treatment of psoroptes infestation in buffalo.  相似文献
