原标题："干得好不好，企业说了算" 此外，松绑减负还体现在不增加额外管理负担等方面。曾有科研人员向记者抱怨，自己受聘于企 业，工作之余要填写工作日志，年底还要接受考核检查，耗费了不少精力。出发点虽好，但无形中给科 研人员增加了负担。 鼓励科研人员深入企业一线，要处理好管理与服务的关系。遵循这一思路，宁夏科技厅此次特地简 化程序，组织开发自治区科创专员选聘工作网络版服务平台，全面推行申报无纸化，实现选聘工作全流 程信息化。 当前，企业科技创新能力弱是宁夏产业创新发展的突出短板。企业普遍面临科技人才短缺、创新效 能不高等问题，通过让科研人员"下沉"一线等举措提升核心竞争力，迫在眉睫。 首批科创专员来自宁夏大学、宁夏农林科学院等8家区内高校院所，以及山东大学、西安交通大 学、中国水产科学研究院、苏州英诺欣医药科技有限公司等25家区外单位。 宁夏此次改革的关键，在于既要激励科研人员深入企业"摸爬滚打"，又要避免给他们造成额外负 担，实现二者的平衡。 记者翻阅选聘管理办法时注意到，支持政策规定"对于选聘的科创专员，通过自治区人才经费每年 给予2万元生活补助"，这与常见的科技项目经费截然不同。 "传统模式下，科研人员花的 ...

科技日报讯 （记者刘霞）美国科罗拉多大学博尔德分校开展的最新研究表明，广泛应用于食品添 加剂的赤藓糖醇，可能对脑血管健康产生不利影响。这项发表于《应用生理学杂志》的研究发现，这种 代糖会引发多重负面效应：加剧氧化应激、干扰一氧化氮信号传导、促进血管收缩肽生成，并削弱脑部 微血管内皮细胞的溶栓能力。 赤藓糖醇甜度为蔗糖的60%—80%，却几乎不含热量，已成为蛋白棒、低卡饮料和糖尿病特制食品 中的常用添加剂。然而随着研究深入，科学家发现其"甜美"外表下可能暗藏隐忧：欧美多项流行病学调 查显示，血液中赤藓糖醇浓度升高与心脑血管疾病发生率存在正相关。 团队表示，当前结论源自实验室条件下的急性暴露实验，实际人体长期摄入的影响仍需通过更深入 的动物实验和临床研究予以验证。 在最新研究中，团队设计了精密的体外实验。他们将培养的人脑微血管内皮细胞暴露于相当于一瓶 饮料含量的赤藓糖醇中，并通过毛细管电泳免疫测定和酶联免疫吸附测定等技术，测量了细胞的氧化应 激、抗氧化蛋白表达、一氧化氮生物利用度、内皮素产生和血栓溶解能力。 结果显示，暴露于赤藓糖醇的血管细胞，其氧化应激水平激增加了75%，虽触发抗氧化防御机制 ——超氧化物歧化酶 ...

Core Viewpoint - Researchers from South China Agricultural University and Henan University of Science and Technology have discovered a new mechanism for selenium transport in rice, providing a theoretical basis for increasing the selenium content in rice and guiding the development of new selenium-rich rice varieties [1][2]. Group 1: Selenium's Importance and Current Challenges - Selenium is an essential trace element for humans, playing a crucial role in enhancing immunity, antioxidant activity, and cancer prevention. A lack of selenium can lead to various health issues, including heart disease and cancer [1]. - Approximately 700 million people in China live in selenium-deficient or low-selenium areas, posing a potential risk for insufficient selenium intake [1]. - Rice, a staple food for half of the global population, generally has low selenium content, primarily in the form of selenomethionine, which is less efficiently absorbed by the human body compared to methylselenocysteine, a more bioavailable form of selenium found in vegetables like broccoli and garlic [1]. Group 2: Research Findings - The study identified a transport protein named NRT1.1B in rice, which functions as a "selenium courier," transporting high-quality selenium from the roots to the stems and leaves during the growth period, and back to the roots for temporary storage [2]. - During the grain-filling stage, this transport protein plays a critical role in efficiently delivering high-quality selenium from the roots and leaves to the developing grains [2]. - The goal of the research is to ensure that every grain of rice can better meet human selenium needs, with plans to further develop these findings into products that provide rice rich in methylselenocysteine [2].
