Microbial Nanocellulose Based Biocomposites For Soft Bone Regeneration: From Present To The Future: From The Present To The Future, Probal Basu, Nabanita Saha, Tomáš Sáha, Petr Sáha

Research Outputs: 2025-Present

Microbial nanocellulose (MC) draws special attention from the research community due to its unique nano-bio fabrication. This nanofiber-constructed biomaterial is biosynthesized by certain microbes in the purest form (devoid of lignin, pectin, and hemicellulose). Due to its striking similarities to animal collagen fibers, MC nanofibers have been used to develop osteoconductive biomaterial for soft tissue regeneration. High surface area, notable rheological properties, and biocompatibility make this material attractive for tissue regeneration. Concurrently, their bio-friendly characteristics are due to various bio-ceramic materials like calcium phosphate (CP) employed in conjunction with MC (for the development of scaffold/bio-composite). The significant interaction between MC's …

The Response Of Mitochondrial Position To Glucose Stimulation In The Min6 Model System, Luis Perez Jul 2025

The Response Of Mitochondrial Position To Glucose Stimulation In The Min6 Model System, Luis Perez

Arts & Sciences Graduate Student Theses and Dissertations

The compartmentalization of eukaryotic cells into membrane-bound organelles with specific subcellular positioning enables precise spatial and temporal control of cellular functions. While functionally significant mitochondrial localization has been demonstrated in cells such as neurons, it remains unclear how general these cell principles are. Here, we examine the spatial organization of mitochondria within MIN6 pancreatic beta cells under variable glucose conditions. We observe glucose-dependent redistributions of mitochondria, favoring peripheral localization at elevated glucose levels when insulin secretion is also elevated. Our results suggest that active mitochondrial transport along microtubules and calcium activity, but not ATP synthesis, are critical regulators of this …

The Bond Of Peace: Restoring Souls In Worship Amid Culture War And Moral Suffering, Steve Yeagley Jul 2025

The Bond Of Peace: Restoring Souls In Worship Amid Culture War And Moral Suffering, Steve Yeagley

Andrews University Seminary Studies (AUSS)

Jeremiah’s critique of war as false worship challenges popular Christianity’s support of American war culture. While primarily expressed as American militarism, war culture also manifests in the rhetoric of culture wars. Adding to the division and violence that the nation’s culture wars can fuel is their potential to inflict moral suffering. Emerging discourses of moral distress and injury suggest that, like wartime environments, culture wars may exact a spiritual toll. Unlike the militant liturgies of war culture, Christian worship can address this moral suffering. When acknowledged in worship through witness and lamentation, moral distress and injury offer a prophetic critique, …
