Abstract
Ionizing radiation (IR) targeted at killing cancer cells also damages normal human cells and tissues through oxidative stress. Thus, the practical treatment of cancer using radiation therapy (RT) is sometimes limited because of the acute side effects in individual patients. In addition, some radioresistant cancers are difficult to treat with limited doses of IR, which leads to treatment failure. Natural chemicals that have unique physiological functions and low toxicity offer significant advantages for the development of new radiation therapies. Natural chemicals can counteract the oxidative damage caused by IR during RT because of their strong antioxidant ability. Certain natural chemicals can also serve as radiosensitizers that can enhance the cancer-killing effects. This review article discusses the main roles of radio-functional natural chemicals in the development of cancer RT.

Abstract
While the broader ambition of the Indian government's Right of Children to Free and Compulsory Education (RTE) Act (2009) has been lauded, scholars have expressed reservations with the universal education measure. One area that has not been adequately addressed within these debates is the instructional medium. While RTE (2009) recognizes children who are "disadvantaged" as linguistic minorities, and stipulates that the "medium of instruction shall, as far as practicable, be in child's mother tongue", it offers little further direction. India is home to more than 1,652 languages, but only 43 languages function as instructional media. Therefore, the majority of children learn in a tongue that is not their home language, experiencing serious educational disadvantages. How this issue complicates the intent of the RTE (2009) Act remains to be explored. This article examines this gap using the theoretical lens of dis-citizenship, which is conceptualized in terms of exclusions experienced by marginalized groups. Here, we focus on those marginalized by the language of instruction. We investigate questions about language access, inclusion, equity, and rights arising from RTE (2009), within the narrative of India's complex, hierarchical multilingualism.

China's sustainable development goals and carbon neutrality targets cannot be achieved without revolutionary transitions of the agricultural sector. The rapid development of digital technologies is believed to play a huge role in this revolution. The ongoing prevention and control of COVID-19 has greatly boosted the penetration of digital technology services in all areas of society, and sustainable transformation driven by digital technologies and services is rapidly becoming an area of innovation and research. Studies have shown that the rapid advancement of digitalization is also accompanied by a series of new governance challenges and problems: (1) unclear strategic orientation and inadequate policy and regulatory responses; (2) various stakeholders have not formed a sustainable community of interest; (3) information explosion is accompanied by information fragmentation and digital divide between countries and populations within countries. Meanwhile, current research has focused more on the role of digital services in urban governance and industrial development and lacks systematic research on its role in sustainable agricultural and rural development. To address the realities faced by different stakeholders in the process of digital transformation of agriculture, this paper aims to propose an inclusive analytical framework based on the meta-governance theory to identify and analyze the demand, supply, actor networks, and incentives in the digital technology-and-services-driven sustainable agricultural transformation, starting from the goals and connotations of sustainable agricultural and rural transformation and the interactions among different stakeholders in governing information flows. This analytical framework is further applied to analyze the cases of China and the EU. Although China and the EU represent different development phases and policy contexts, the framework is valid for capturing the characteristics of information flows and actor networks along the flows. It is concluded that a common information platform based on the stakeholder network would benefit all stakeholders, help reach common framing of issues, and maintain a dynamic exchange of information. Depending on the country context, different types of stakeholders may play different roles in creating, supervising, and maintaining such platforms. Digital infrastructures/products as hardware and farmers digital capacity as 'software' are the two wings for digital sustainable transformation. Innovative incentives from different countries may inspire each other. In any case, farmers' actual farming behavior changes should be an important criterion for evaluating the effects and effectiveness of digital transition governance.
