浙江省野生动植物进出口现状及管理对策

open access: yes野生动物学报, 2004
浙江省野生动植物资源丰富,对外贸易活跃。据统计,2003年浙江省野生动植物及其产品贸易额达24.5亿元,比前两年有大幅增加(2001年为19亿元,2002年为21.5亿元),这充分说明野生动植物对外贸易已日益成为浙江省经济发展的一大新亮点。研究分析野生动植物进出口中的基本情况、及时发现新问题、制定新对策,已成为当前进一步规范野生动植物进出口管理的重要课题。

Checklist and the floral analysis of benthic seaweeds in Zhejiang Province(浙江底栖海藻及其区系分析)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2002
报道浙江潮间带底栖海藻211种,其中蓝藻门11种、绿藻门34种、褐藻门38种、红藻门128种.根据地理分布分析,其中有2/3的藻种由中国南海随台湾暖流北上而传入浙江海域,来自北方的温带藻种及本地种均不多,因此,浙江海区以亚热带藻种占绝对优势,达69.2%,热带成分1.4%,温带成分26.5%,本地种2.4%.同时,与南北海藻区系的相似系数比较以及对及值(R:红藻,P:褐藻,C:绿藻)的分析,均显示浙江海区海藻属于亚热带海洋植物区系.

Study on focal points of fundamental research of sciences in Zhejiang Province during the "11th Five Year Program" through entropy analysis(基于熵值法的浙江省“十一五”基础研究热点分析与思考)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2011
熵值法是一种科学、简单、实用的综合评价方法.由于熵值法是一种客观赋权法,因此可以避免人为因素带来的偏差.以浙江省“十一五”期间6个基础研究学科领域获得浙江省自然科学基金资助项目的情况作为数据源,采用熵值法对这些数据进行分析总结,揭示了浙江省在基础学科领域的研究热点,并据此对浙江省“十二五”期间基础学科领域的研究发展趋势进行了预测和思考.

Cloning and sequencing of protein C activator gene from Agkistrodon blomhoffii brevicaudus(江浙蝮蛇蛇毒蛋白C激活因子基因的克隆及测序)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2003
从江浙蝮蛇毒腺中抽提总RNA,RT-PCR进行体外扩增,获得江浙蝮蛇蛇毒蛋白C激活因子基因,克隆至pGEx-5x-3载体中.对3个重组克隆分别作DNA全序列分析,通过遗传密码推导出相应的氨基酸序列.与其它已知的丝氨酸蛋白酶型蛇毒蛋白的氨基酸作比较,其中许多位置上氨基酸有很强的同源性.该基因的成功克隆,不仅推导出江浙蝮蛇蛇毒蛋白C激活因子的蛋白质序列,也为进一步开展江浙蝮蛇蛇毒蛋白C激活因子蛋白质工程的研究工作打下良好的基础.

N–O Dual Functional Group Transposition via Energy Transfer Photocatalysis

open access: yesAdvanced Science, EarlyView.
N–O dual functional group transposition (dFGT) enabled by the photocatalytic energy transfer (EnT) has been developed. This methodology is applicable to both activated and unactivated alkyl derivatives for dFGT, and it also successfully extended to N–N dFGT, demonstrating its general applicability.

A Blood‐Derived Factor Rescues ALS: Platelet Factor 4 Activates OPTN‐Dependent Autophagy to Clear SOD1 Aggregates Independently of PINK1

open access: yesAdvanced Science, EarlyView.
Systemic platelet factor 4 (PF4) is significantly depleted in amyotrophic lateral sclerosis (ALS). Peripheral PF4 replenishment restores central proteostasis by driving OPTN‐dependent, PINK1‐independent selective autophagy in motor neurons. This intervention effectively clears toxic SOD1 aggregates, blunts glial activation, and preserves neuromuscular ...
