评论：最新研究：抗衰老不切实际 抗氧化剂保健品多为炒作 |
|
|
何为生命? 生命之存在, 依赖于生物大分子间的电子转移, 这种转移从生物化学角度而言，便是氧化还原反应(reduction-oxidation, Redox)。当电子能顺畅地在生物大分子间流动时, 各种生物功能便得以实现。否则，某些生物功能可能受阻，生物体(包括人类)便可能生病甚至死亡。氧化剂是指一类化学物质, 它们的化学结构不稳定，需要夺取周围环境中其他生物分子中的电子以达到稳定状态。但其结果是被夺走电子的生物大分子失去了电子(被氧化了)，因而无法参与生命活动中它们应该起到的作用。抗氧化剂是指一类既能给出电子，又能接受电子的生物分子，其主要功能是保证生命活动中的生物化学反应能继续下去。氧化剂与抗氧化剂的区别在于氧化剂只能单向地夺取电子，而抗氧化剂则能双向地给出或接受电子。各种疾病, 包括癌症, 衰老, 最终都与体内(细胞内)氧化剂增加而导致的细胞及细胞内成分(DNA, 线粒体, 细胞膜等)换伤有关。最典型的例子是砒霜。砒霜阻断线粒体产能途径上的电子转移, 导致能量产生中断, 细胞死亡。
氧化剂来源:
内源: 代谢产物, 尤其是线粒体代谢, 产生最多的氧化剂。肠胃道毒素(牙毒素, 尤其是根管治疗过的牙齿; 消化不良的食物, 如常用抗酸药制胃痛者常有此问题; 有肠微漏(Leaky Gut)者, 菌群紊乱(dysbiosis)者, 尤其如此。
外源: 食物, 药物, 环境污染物(雾霾, 水等), 细菌, 病毒, X射线, 电磁波(EMF), 生活化学物品(化妆, 护肤, 清洁剂), 等。
何为氧化压力(Oxidative Stress, OS)? OS=氧化剂(自由基)/抗氧化剂. 现代农业由于土壤营养下降, 污染增加, 导致蔬菜水果质量下降。现代人新鲜蔬果食用减少，而且我们吃的蔬果从地里到口中的时间(冰箱保存)至少几天甚至更久，导致抗氧化剂含量下降。加上我们的生活环境中各种氧化剂的增加，结果是氧化压力的普遍增加。

Dear Colleague,
This is to inform you that the deadline to submit a talk proposal to the 13th SICC International Tutorial Workshop "Topics in Nonlinear Dynamics" has been extended to Wednesday, October 10. The workshop will be held at the Politecnico di Torino, 29-30 October 2018, focusing is on the fascinating theme of "Complexity and the city".
You can submit the talk proposal in the form of a one-page abstract to complexcity@polito.it. The talk consists in a presentation of 20 timed slides shown for 20 seconds each (6 minutes 40 seconds in total), a unique, fun, and challenging way to communicate your research and receive feedback!
The normal registration to the workshop can be done at https://complexcity.polito.it/registration/
AIM AND SCOPE
The workshop is the 13th of a series of tutorial workshops annually organized to explore the emergence of new research fields in which modeling, analysis and control of nonlinear and complex systems play a role of growing importance. These workshops have been traditionally devoted to an interdisciplinary audience with particular attention to PhD students and young researchers. The theme of this year is “Complexity and The City” with a unique focus on interactions, mobility, epidemics, information and misinformation spreading, and many other complex phenomena typical of urban environments.
The workshop will gather scholars, students, and practitioners for two days of presentations and debates around complex systems science and its interplay with urban environments. A series of plenary lectures from renowned scholars is planned, while PhD students and young researchers will have dedicated sessions to present their research activity in an effective and appealing way. Social events will foster interaction and creation of collaboration opportunities.

The Oct 12-14 Fall CCA Conference is cancelled due to a strike of the operating engineers Local 39 at the DoubleTree San Jose. Local 39 went out on strike, October 9th, at the DoubleTree San Jose hotel. We have been in contact with the local and they have asked for our support in their labor dispute and they are not optimistic at this point that the strike will end soon. Just as we supported our sisters and brothers from Unite Here Local 19 that went on strike at the Marriott San Jose last week, we feel it is important to support Local 39 as well. We have investigated other options for holding the Fall Conference at another venue but are unable to find a suitable location on such short notice and as a result, we are cancelling the conference.
What to do Next?
If you made a room reservation at the DoubleTree or Hilton Santa Clara using the CCA Conference link, CTA will cancel those room reservations for you immediately. If you made a reservation at another hotel, you will need to cancel those reservations directly with the hotel as soon as possible to avoid cancellation penalties. If you booked air travel, you will need to cancel your flight reservations as soon as possible. A follow-up email will be forthcoming to delegates regarding questions about reimbursement for incurred expenses. If you have any questions, please contact Nessa Connor at CTA Conference Coordination Center at 650-552-5167 or email ccaconference@cta.org.
