Developing models of the small intestine

Abstract

Tissue engineering laboratory models of the small intestine. Tissue Engineering Part B, 24(2), 98-111. A schematic diagram illustrating the morphology of the small intestinal layers was chosen as the art cover for the journal.

Advancing intestinal organoid technology to decipher nano-intestine interactions and treat intestinal disease

“…In addition, the group also demonstrated that the hydrogel could be used as a carrier for intestinal organoid transplantation in vivo. The intestinal organoids, which were transplanted with the PEG hydrogels, effectively improved colonic wound repair [42]. In addition, Capeling et al designed a simple hydrogel out of unmodified alginate, which served only as a simple physical scaffold for 3D intestinal organoid culture [15].…”

China's Strategy and Activities in the Arctic: Implications for North American and Transatlantic Security

“…Therefore, the assessments in the next section should be treated somewhat speculatively and are derived from the overall military strategy, capabilities, and direction of development of the PLA, which regards global commons and transnational spaces, such as the poles, the deep sea, outer space, and cyberspace, as "new strategic frontiers" (战略新疆域) where great-power strategic competition is expected to be intense. 30 China's Goals in the North American Arctic China's overall foreign policy focuses on the realization of the "China Dream" of national rejuvenation, the recouping of supposedly "lost territories," such as Taiwan, various uninhabited maritime features in the East and South China seas, and sometimes territory in the presentday Russian Far East lost to Imperial Russia during the Qing Dynasty, as well as the establishment of a position of preeminence, first regionally, and then eventually globally. 31 In the course of China's quest for greater regional influence, PRC officials and authors tend to treat the United States and its network of alliances and partners, as well as the liberal international order they are embedded in and generally supportive of, as key obstacles to the accomplishment of China's ambitions.…”

“…29 In Greenland, for the Citronen Fjord project, the China Nonferrous Metal Mining Group Company (CNMC) is partnering with Ironbark, an Australian mining firm. 30 Chinese mining activities in Alaska are much more limited than in Canada and Greenland. In 2009, CIC purchased a stake in Teck Resources, the parent company of the Red Dog Mine, which is focused on zinc mining.…”

“…In other cases, when formal bidding processes were in place, there were concerns that the process was also tainted by corrupt practices that resulted in inflated prices for the projects and waste. 30 These practices have economic, social, and environmental consequences in the host country. With weakened domestic governance structures, host countries are more prone to instability and to being susceptible to China projecting influence and potentially gaining military access to their territories.…”

“…29 Like Canada, the United States has FDI screening laws that apply to the entire country rather than Arctic-specific ones. 30 In Overfield et al, 2022, which undertook an exhaustive analysis of FDI screening mechanisms in the Arctic, the authors describe the U.S. process in this regard as "highly formal and structured," and note that "the 2018 Foreign Investment Risk Review Modernization Act (FIRRMA) amendment to the DPA [Defense Production Act] established formal sector-specific screening requirements in real estate, infrastructure, technology, and data." 31 Such screening is done by the interagency Committee on Foreign Investment in the United States (CFIUS).…”
