RAFA: RNA all-atom structure reconstruction from sparse anchor coordinates

SUMMARY: We present RAFA, a C ++ command-line tool for RNA all-atom structure reconstruction from sparse or partial coordinates. RAFA targets settings in which coarse-grained modelling, low-resolution fitting, or partial experimental interpretation provides RNA anchor atoms but n...

Presenting a new scoring system based on clinical and inflammatory factors to classify the severity of bipolar disorder

Background Various clinical and laboratory factors are related to the severity of bipolar disorder, but there is no global agreement for the role of these factors.Methods Forty patients with the definitive diagnosis of bipolar disorder were included in this prospective study. The...

Non-noble Metal Oxide Catalysts for CO Oxidation in Humid and Sulfur-Containing Streams: From Activity Competition to Stability Challenges

The efficient removal of carbon monoxide from industrial and vehicular emissions has become a pressing practical challenge, driven by tightening emission standards and growing concerns over ambient air quality. Noble metal catalysts, despite their excellent low-temperature activi...

Prioritising Content for Continuing Education in Non-Invasive Ventilation Care: A Needs Assessment Survey of Intensive Care Unit Nurses

Background: The success of non-invasive ventilation (NIV) depends on bedside nursing judgement, yet nurses report insufficient preparation, and educational content is usually decided before the competencies nurses most need are identified. Objectives: To prioritise NIV competenci...

Platinum Group Metal Recovery from End-of-Life Ammonia Oxidation Catalysts in Oxidative Chloride Media

Platinum group metals (PGMs) are critical raw materials, and their sustainable recovery from secondary sources supports supply security and a circular economy. End-of-life ammonia oxidation catalysts are considered attractive feedstocks due to their high PGM content. A systematic...

Integration of Renewable Energy Sources into Saudi Smart Grids: Challenges, Optimization Strategies and Future Opportunities

Saudi Arabia is making the shift from a centrally controlled electricity system that is based on hydrocarbons to one that is digitally coordinated, in which large-scale solar and wind power, distributed energy resources, storage systems, flexible demand, and power-electronic inte...

A Comprehensive Review on the Antimicrobial Culture Susceptibility Patterns and Intravenous-to-Oral Conversion of Antibiotics

Abstract Antimicrobial resistance is a major challenge in managing bacterial infections, emphasizing appropriate antibiotic selection, culture-directed therapy, and antimicrobial stewardship. This review summarizes antimicrobial culture and susceptibility patterns and examines th...

Cell-free RNA in spent embryo medium for non-invasive assessment of preimplantation embryo quality: a review

Embryo quality assessment of preimplantation was a key step that affects the treatment outcomes of assisted reproductive technology (ART). Conventional morphological grading and time-lapse imaging (TLI) were widely used in clinical embryo selection. However, these methods mainly...

Comparative Toxicity of Antifouling Paint Particle Suspensions and Dissolved Leachates in the Marine Copepod Tigriopus japonicus

Antifouling paint particles (APPs), generated by coating degradation and ship-maintenance activities, are an emerging but poorly characterized source of marine pollution. APPs can release particle-associated and dissolved toxicants, yet their relative contributions to toxicity re...
