| 1 | Influence of selenium induced oxidative stress on spermatogenesis and lactate dehydrogenase-X in mice testis显示文摘Aim: To evaluate the effect of oxidative stress on the spermatogenesis and lactate dehydrogenase-X (LDH-X) activity in mouse testis. Methods: For creating different levels of oxidative stress in mice, three selenium (Se) level diets were fed in separate groups for 8 weeks. Group 1 animals were fed yeast-based Se-deficient (0.02 ppm) diet. Group 2 and Group 3 animals were fed with the same diet supplemented with 0.2 ppm and 1 ppm Se as sodium selenite, respectively. After 8 weeks, biochemical and histopathological observations of the testis were carried out. LDH-X levels in the testis were analyzed by western immunoblot and ELISA. Results: A significant decrease in testis Se level was observed in Group 1 animals, whereas it was enhanced in Group 3 as compared to Group 2. The glutathione peroxidase (GSH-Px) activity was significantly reduced in both the liver and testis in Group 1, but not in Group 2 and 3. A significant increase in the testis glutathione-S-transferase (GST) activity was observed in Group 1,whereas no significant change was seen in Groups 2 and 3. Histological analysis of testis revealed a normal structure in Group 2. A significant decrease in the germ cell population in Group 1 was observed as compared to Group 2 with the spermatids and mature sperm affected the most. Decrease in the lumen size was also observed. In the Se-excess group (Group 3), displacement of germ cell population was observed. Further, a decrease in the LDH-X level in testis was observed in Group 1. Conclusion: Excessive oxidative stress in the Se deficient group, as indicated by changes in the GSH-Px/GST activity, affects the spermatogenic process with a reduction in mature sperm and in turn the LDH-X level.

| 2 | In vitro evaluation of antimicrobial and antioxidant activities of methanolic extract of Jasminum humile Leaves显示文摘Objective:To evaluate in vitro antimicrobial and antioxidant activities of methanolic extract of Jasminum humile(J.humile) leaves extract.Method:Methanolic extract of J.humile was evaluated for its antimicrobial activity by using agar well diffusion method & their possible antioxidant assay by two complementary test systems,namely DPPH and hydrogen peroxide scavenging activity.These various antioxidant activities were compared to standard antioxidants such as ascorbic acid for both the tests.Results:In the DPPH & hydrogen peroxide scavenging activity,the IC50 value of methanol extract was 70.43μg/mL & 60.79μg/mL respectively. Further,the extract showed inhibitory activity for Gram-positive and negative bacteria at different concentrations.The maximum antibacterial activity of extract was exhibited against Staphylococcus aureus(S.aureus) at concentration 50 mg/mL when compared with ciprofloxacin Conclusions:These results clearly indicate that J.humile is effective in scavenging free radicals and has the potential to be a powerful antioxidant.Thus,the results obtained in the present study indicate that J.humile leaves extract could be considered as a potential source of natural antioxidants and that could be used as an effective source against bacterial diseases. | Parminder Nain Ashok Kumar Sunil Sharma Jaspreet Nain | 2011 | Asian Pacific Journal of Tropical Medicine2011,4,10: | 3 |
| 3 | 华北上新世-更新世过渡期植被、气候与大气CO2研究进展显示文摘上新世-更新世过渡期是新生代全球气候变化的重要拐点之一,此期气候经历了由'暖室'向'冰室'的转变。研究该气候转型期的特征可为科学界和国家层面应对现在和未来的全球气候变暖提供理论基础和实践指导。通过深入研究中国华北山西榆社盆地张村组上新世-更新世过渡期地层中保存的植物大化石、孢粉以及硅藻组合,为重建该时段陆地生态系统中植被演替和气候变化提供坚实的生物学证据。在综合回顾张村组化石植物研究历史的基础上,侧重介绍最近5年在古植被、古气候、古环境以及古大气CO2浓度重建等方面的最新进展。这些新成果定性及定量地刻画了第三纪-第四纪之交中国北方黄土高原东南缘气候变干、变凉的转型过程及其陆地生态系统中大气CO2浓度先升后降的变化趋势。 | 白云俊 魏雪苹 秦锋 李亚蒙 李金锋 Parminder S.Ranhotra 王宇飞 | 2016 | 植物学报2016,51,2: | 2 |
