A highly-reactive vinyl ether-functionalized aliphatic polycarbonate and its block copolymer were developed as templates for multiple post-polymerization conjugation chemistries. The vinyl ether-functional six-membered cyclic carbonate monomer was synthesized by a well-established two-step procedure starting from 2,2-bis(hydroxymethyl)propionic acid. An organobase-catalyzed ring-opening polymerization of the synthesized monomer afforded polycarbonates with pendant vinyl ether functionalities (PMVEC). The vinyl ether moieties on the resulting polymers were readily conjugated with hydroxyl- or thiol-containing compounds via three different post-polymerization modification chemistries - acetalization, thio-acetalization, and thiol-ene reaction...

Recent wildland urban interface fires have demonstrated the unrelenting destructive nature of these events and have called for an urgent need to address the problem. The Wildfire paradox reinforces the ideology that forest fires are inevitable and are actually beneficial; therefore focus should to be shifted towards minimizing potential losses to communities. This requires the development of vulnerability-based frameworks that can be used to provide holistic understanding of risk. In this study, we devise a probabilistic approach for quantifying community vulnerability to wildfires by applying concepts of graph theory...

INTRODUCTION: The optimal management of locally advanced recto-sigmoid cancer is unclear. Although some experts advocate for upfront surgery, others recommend neoadjuvant chemoradiation followed by surgery. We used the National Cancer Database to characterize patterns-of-care and overall survival (OS) associated with these treatment strategies. PATIENTS AND METHODS: Patients with clinical stage II or III recto-sigmoid cancer who underwent surgery with or without adjunctive chemotherapy and/or radiotherapy from 2006 to 2014 were identified, and dichotomized into: (1) upfront surgery, and (2) neoadjuvant chemoradiation cohorts...

The rapid growth of cruise ship tourism increases the use of historic port cities as strategic hubs for cruise ship operators. Benefits derived from increased tourism for the municipality and cruise ships are often at odds with the environmental and social impacts associated with continued historical port use. This study illustrates the use of Multi-Criteria Decision Analysis (MCDA) for weighing of various criteria and metrics related to the environment, economy, and social sustainability for the selection of a sustainable cruise line route...

Hyperglycaemia is a major contributor to diabetic cardiovascular disease with hyperglycaemia-induced endothelial dysfunction recognized as the initiating cause. Coagulation pathway-regulated proteinase-activated receptors (PARs) that can regulate vascular tone in vivo cause eNOS-mediated endothelium-dependent vasodilation; but, the impact of hyperglycaemia on this vasodilatory action of PAR stimulation and the signalling pathways involved are unknown. We hypothesized that vascular sodium-glucose co-transporter 2 activity and hyperglycaemia-induced oxidative stress involving Src-kinase, EGF receptor-kinase, Rho-kinase and protein-kinase-C biochemical signalling pathways would compromise PAR2-mediated endothelium-dependent vasodilation...

The oral fluid microbiome comprises an important bacterial diversity, yet the presence of archaea has not been reported so far. In order to quest for the presence of methanogenic archaea (methanogens) in oral fluid, we used a polyphasic approach including PCR-sequencing detection, microscopic observation by fluorescence in-situ hybridization, isolation and culture, molecular identification and genotyping of methanogens in 200 oral fluid specimens. In the presence of negative controls, 64/200 (32%) prospectively analysed oral fluid specimens were PCR-positive for methanogens, all identified as Methanobrevibacter oralis by sequencing...
