| 1 | High-throughput microfabrication of axially tunable helices显示文摘Helical structures exhibit novel optical and mechanical properties and are commonly used in different fields such as metamaterials and microfluidics. A few methods exist for fabricating helical microstructures, but none of them has the throughput or flexibility required for patterning a large surface area with tunable pitch. In this paper, we report a method for fabricating helical structures with adjustable forms over large areas based on multiphoton polymerization(MPP) using single-exposure, three dimensionally structured, self-accelerating, axially tunable light fields. The light fields are generated as a superposition of high-order Bessel modes and have a closed-form expression relating the design of the phase mask to the rotation rate of the beam. The method is used to fabricate helices with different pitches and handedness in the material SU-8. Compared to point-by-point scanning, the method reported here can be used to reduce fabrication time by two orders of magnitude, paving the way for adopting MPP in many industrial applications. | He Cheng Pooria Golvari Chun Xia Mingman Sun Meng Zhang Stephen M.Kuebler Xiaoming Yu | 2022 | Photonics Research2022，10，2： | 4 |

| 4 | Optimal dose of zinc supplementation for preventing aluminum-induced neurotoxicity in rats显示文摘Zinc supplementation can help maintain learning and memory function in rodents.In this study,we hypothesized that zinc supplementation could antagonize the neurotoxicity induced by aluminum in rats.Animals were fed a diet containing different doses of zinc(50,100,200 mg/kg)for 9 weeks,and orally administered aluminum chloride(300 mg/kg daily)from the third week for 7 consecutive weeks.Open-field behavioral test results showed that the number of rearings in the group given the100 mg/kg zinc supplement was significantly increased compared with the group given the50 mg/kg zinc supplement.Malondialdehyde content in the cerebrum was significantly decreased,while dopamine and 5-hydroxytryptamine levels were increased in the groups given the diet supplemented with 100 and 200 mg/kg zinc,compared with the group given the diet supplemented with50 mg/kg zinc.The acetylcholinesterase activity in the cerebrum was significantly decreased in the group given the 100 mg/kg zinc supplement.Hematoxylin-eosin staining revealed evident pathological damage in the hippocampus of rats in the group given the diet supplemented with 50 mg/kg zinc,but the damage was attenuated in the groups given the diet supplemented with 100 and200 mg/kg zinc.Our findings suggest that zinc is a potential neuroprotective agent against aluminum-induced neurotoxicity in rats,and the optimal dosages are 100 and 200 mg/kg. | Hao Lu Jianyang Hu Jing Li Wei Pang Yandan Hu Hongpeng Yang Wenjie Li Chengyu Huang Mingman Zhang Yugang Jiang | 2013 | Neural Regeneration Research2013，8，29： | 0 |
