Whole-Body MRI in Children: Concepts and Controversies- Expert Panel Narrative Review.

The use of whole-body MRI (WBMRI) in children, from infancy to adolescence, has expanded rapidly over the past decade, with increasing uptake and a broadening range of clinical indications. Current indications include screening for presymptomatic lesions in cancer predisposition syndromes; tumor staging in known malignancies; investigating fevers of unknown origin; as well as diagnosing and monitoring rheumatologic diseases, vascular anomalies and neuromuscular disorders. This AJR Expert Panel Narrative Review aims to offer a comprehensive discussion of WBMRI in pediatric patients, exploring protocols and other technical considerations, clinical indications, implementation challenges and troubleshooting, as well as controversies in widespread adoption, while considering emerging trends and directions.

Isolation of marine-derived filamentous fungi and their potential application for bioremediation process.

We evaluated the bioremediation potential of petroleum-derived compounds using fungal strains isolated from marine samples collected on the coast of the states of Paraná, Brazil. About 75 isolated filamentous fungi were subjected to assays including decolorization of the synthetic dye Remazol Brilliant Blue R (RBBR), tolerance to diesel oil, production of bioemulsifying and degradation of pyrene. Nine isolates could decolorize RBBR between 3.

12.1 terabit/second data center interconnects using O-band coherent transmission with QD-MLL frequency combs.

Most current Data Center Interconnects (DCI) use intensity modulation direct detection (IMDD) configurations due to their low complexity and cost. However, significant scaling challenges allow coherent solutions to become contenders in these short reach applications. We present an O-band coherent optical fiber transmission system based on Quantum Dot-Mode Locked Lasers (QD-MLLs) using two independent free-running comb lasers, one each for the carrier and the Local Oscillator (LO).

Hybrid Organic-Inorganic Blast Furnace Slag Binders Activated with Alkali Acetates.

Hybrid organic-inorganic binders based on blast furnace slag were produced using sodium (NaAc) or potassium (KAc) acetate as the sole activator, and their properties were compared with those of sodium- or potassium hydroxide-activated slag pastes. The acetate-activated binders showed significantly lower cumulative heat release and extended setting time (∼230 h) than the hydroxide-activated binders. The main reaction products forming in all binders were calcium aluminosilicate hydrate-type gels and a hydrotalcite-like phase, independently of the activator type used.
