Announced in February 2021, the Green Plan represents a concerted national-level strategic shift towards advancing the sustainability agenda in Singapore. With sustainable development now being a ‘major policy priority’, it is inevitable that the Green Plan will have important legal implications, each of which will be identified and analysed in this paper. More broadly, however, the paper also suggests that the Green Plan will open up valuable opportunities for environmental law to receive greater …

That’S Me In The Spotlight: Self-Relevance Modulates Attentional Breadth, M Golubickis, Cn Macrae

School of Psychology

A core prediction of models of social-cognitive functioning is that attention is preferentially tuned to self-relevant material. Surprisingly, however, evidence in support of this viewpoint is scant. Remedying this situation, here we demonstrated that self-relevance influences the distribution of attentional resources during decisional processing. In a flanker task (N = 60), participants reported if to-be-judged stimuli either denoted, or were owned by, the self or a friend. A consistent pattern of results emerged across both judgment tasks. Whereas the identification of friend-related targets was speeded when the items were flanked by compatible compared with incompatible flankers, responses to self-related targets …

Dysregulation Of Mir-21-Associated Mirna Regulatory Networks By Chronic Ethanol Consumption Impairs Liver Regeneration., Austin Parrish, Ankita Srivastava, Egle Juskeviciute, Jan B Hoek, Rajanikanth Vadigepalli

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Impaired liver regeneration has been considered as a hallmark of progression of alcohol-associated liver disease. Our previous studies demonstrated that in vivo inhibition of the microRNA (miRNA) miR21 can restore regenerative capacity of the liver in chronic ethanol-fed animals. The present study focuses on the role of microRNA regulatory networks that are likely to mediate the miR-21 action. Rats were chronically fed an ethanol-enriched diet along with pair-fed control animals and treated with AM21 (anti-miR-21), a locked nucleic acid antisense to miR-21. Partial hepatectomy (PHx) was performed and miRNA expression profiling over the course of liver regeneration was assessed. Our …

Therefore, this work aims to design an effective microwave head imaging system for the detection of …

Using Peptide Design To Engineer Polyelectrolyte Complex Biomaterials, Sara Tabandeh

Electronic Theses and Dissertations, 2020-2023

The self-assembly of oppositely charged polymers provides a versatile platform to design materials for diverse applications in biology and medicine. Electrostatically-driven phase separation of oppositely charged polymers in aqueous solution gives rise to the formation of a polymer-rich phase called a polyelectrolyte complex (PEC). PECs can be in the form of liquid droplets (complex coacervates) or amorphous solid precipitates. Unlike synthetic polymers, peptides are good candidates for developing tailor-made formulations and structure-property relationships due to their biocompatibility, precise control over sequences, and ability to program hydrogen bonding interactions. However, little is known about the effect of combining additional molecular interactions …
