Targeted delivery of hepatitis C virus-specific short hairpin RNA in mouse liver using Sendai virosomes

Internal ribosome entry site (IRES)-mediated translation of input viral RNA is the initial required step for the replication of the positive-stranded genome of hepatitis C virus (HCV). We have shown previously the importance of the GCAC sequence near the initiator AUG within the stem and loop IV (SLIV) region in mediating ribosome assembly on HCV RNA. Here, we demonstrate selective inhibition of HCV-IRES-mediated translation using short hairpin (sh)RNA targeting the same site within the HCV IRES. sh-SLIV showed significant inhibition of viral RNA replication in a human hepatocellular carcinoma (Huh7) cell line harbouring a HCV monocistronic replicon. More importantly, co-transfection of infectious HCV-H77s RNA and sh-SLIV in Huh7.5 cells successfully demonstrated a significant decrease in viral RNA in HCV cell culture. Additionally, we report, for the first time, the targeted delivery of sh-SLIV RNA into mice liver using Sendai virosomes and demonstrate selective inhibition of HCV-IRES-mediated translation. Results provide the proof of concept that Sendai virosomes could be used for the efficient delivery of shRNAs into liver tissue to block HCV replication.

Synthesis of radio frequency plasma polymerized non-synthetic Terpinen-4-ol thin films

Recent advancements in the area of organic polymer applications demand novel and advanced materials with desirable surface, optical and electrical properties to employ in emerging technologies. This study examines the fabrication and characterization of polymer thin films from non-synthetic Terpinen-4-ol monomer using radio frequency plasma polymerization. The optical properties, thickness and roughness of the thin films were studied in the wavelength range 200–1000 nm using ellipsometry. The polymer thin films of thickness from 100 nm to 1000 nm were fabricated and the films exhibited smooth and defect-free surfaces. At 500 nm wavelength, the refractive index and extinction coefficient were found to be 1.55 and 0.0007 respectively. The energy gap was estimated to be 2.67 eV, the value falling into the semiconducting Eg region. The obtained optical and surface properties of Terpinen-4-ol based films substantiate their candidacy as a promising low-cost material with potential applications in electronics, optics, and biomedical industries.

The sublime, affective process + architectural production

A year before Kate Nesbitt’s Theorising a New Agenda For Architecture (1996), the author penned a chapter on the significance of the sublime and its contribution to post-modern architecture via the uncanny or disturbing through the theories of Vidler and Eisenman (Nesbit, 1995). Twenty years on, we see its ongoing presence within the contemporary works of artists Kapoor, Ellison and Viola. Eisenmann and Libeskind aside, explicit reference to the Sublime whether through architectural praxis or theory appears to have been trumped by ecological derivatives and associated transactions, as catalyst for new architecture and architectural thinking. For Edmund Burke (1757), the Sublime was seen as a leading, an overpowering of self to a state of intense self-presence, often leading to a state of otherness. To experience the sublime is to experience affect, physiologically overwhelming the mental faculties through intensities of astonishment, terror, obscurity, magnificence, and reverence. Key here is Burke’s articulation of the stages of the sublime encounter, particularly so, its implications for the process of production which architectural theorists appear to have overstepped in their valorisation of the sublime object. This paper seeks to resituate the sublime within the context of architectural production. Through concepts such as material thinking, bodies and making strange, the paper explores a shift in focus toward affective processes traced from Burke’s inquiry. Rather than proposing strategies solely for affect within the work itself, the focus lies upon the designing experience, where blockage and desirous forces are critical partners in the process of production, as revealed through recent studio programs entitled Strange Space.
