The construction industry (CI) is responsible for consuming 3 billion tons of natural raw materials annually. Also, as per the survey by World Resources Institute, the CI accounts for 40 % of the total waste generated globally. The solution to this inefficient resource usage and adverse effects on the ecosystem is implementing Circular Economy (CE) practices in CI. However, the concept of circular construction is in developmental stages. Therefore, it is more prone to damaging risks than traditional construction. The primary aim of this study is to identify and assess the risk related to implementing CE practices in developing country construction sector. To achieve this aim, 25 risks were shortlisted from the literature review and evaluated upon the probability, detection, and severity risk criteria. This study proposed a novel hybrid fuzzy Multi-Criteria Decision Making (MCDM) approach to analyze the shortlisted risks. Fuzzy Step Wise Assessment Ratio Analysis (FSWARA) is employed to gauge the risk criterion weightage. Moreover, Fuzzy VIKOR (FVIKOR) is used to determine the risks' ranking as per the weightage of the risk criterion. The analyses ranked "lack of political support and incentives for circular construction", "difficulty in selection of circular construction experts", "profit uncertainty", and "circular material quality" as the most critical risks. Therefore, it is recommended for legislative authority to devise a framework that promotes and provides support to circular construction. Moreover, this study fills the literature gap by assessing the risks of CE practices in the CI of Pakistan.

Frame configuration for the management of complex tibial fractures is highly variable and is dependent upon both fracture pattern and surgeon preference. The optimal number of rings to use when designing a frame remains uncertain. Traditionally larger, multi-ring-per-segment constructs have been assumed to offer optimal stability and therefore favourable conditions for fracture healing but there is little in-vivo evidence for this and the recent concept of reverse dynamisation challenges this approach.

Our aim was to evaluate the regulation of messenger RNAs (mRNAs) and biological pathways by long non-coding RNAs (lncRNAs) and circular RNAs (circRNAs) in ischemic stroke. We employed weighted gene co-expression network analysis (WGCNA) to construct two co-expression networks for mRNAs with circRNAs and lncRNAs, respectively, to investigate their association with ischemic stroke. We compared the overlap of mRNAs and biological pathways in the stroke-associated modules of the two networks.

This study aimed to investigate the role of circular RNAs (circRNAs) in sepsis-induced acute gastrointestinal injury (AGI), focusing on their potential as biomarkers and their involvement in disease progression. Peripheral blood samples from 14 patients with sepsis-induced AGI and healthy volunteers were collected. RNA sequencing was performed to profile circRNA and miRNA expression.

Sustainability and environmental protection are reshaping industries, including construction, where sustainability plays a crucial role in its influence on global resource consumption and waste management. The current study has developed a reusable cement material by photo-chemical surface modification of marble powder, achieved by reacting glycidyl methacrylate with carbonate functionality. This innovative modified marble powder boosts the reusability of construction materials, unlocking new possibilities for sustainable building practices.

Background: Myocardial ischemia/reperfusion (I/R) injury, which is associated with high morbidity and mortality, is a main cause of unexpected myocardial injury after acute myocardial infarction. However, the underlying mechanism remains unclear. Circular RNAs (circRNAs), which are formed from protein-coding genes, can sequester microRNAs or proteins, modulate transcription and interfere with splicing.
