ESC Heart Failure, Volume 10, Issue 2, Page 1401-1411, April 2023., 2023 Abstract Aims Diabetic cardiomyopathy (DCM) is one of the major cardiovascular complications of diabetes. However, the mechanism of DCM is not fully understood. Studies have confirmed that certain microRNAs (miRNAs/miRs) are key regulators of DCM. The aim of this study was to investigate the role and mechanism of microRNA (miR)‐494 in cardiomyocyte ...

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.The study shows that Bacillus firmus‐based bionematicides modulate soil microbiota and enhance soybean growth in the Pampa biome. Effects vary by location and time, with increased beneficial bacteria, reduced fungi, and decreased root nematode infestation. Overall, B.

Water Resources Research, Volume 62, Issue 5, May 2026.Abstract Eddy‐resolving numerical simulations are conducted to investigate the effects of density contrast between the confluent flows on hydrodynamics, coherent structures and mixing downstream of the confluence between the Negro and Solimões Rivers, Brazil, which is characterized by both a large discharge (>100,000 m3/s) and a large aspect‐ratio (W/D

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract Two sediment cores were collected from a submarine sediment wave field on the flank of Macauley volcano. Combined with seismic reflection surveys and numerical modeling, we present an integrated model of the formation of large‐scale, eruption‐fed, submarine sediment waves. The sediment waves are large (>100 m high, 1.5 km wide, tens of km long)

Densimetric fractionation with sodium polytungstate to investigate physical protection of soil organic matter [PDF]
, 2008 O fracionamento físico densimétrico é uma técnica que permite estudar a proteção física da matéria orgânica (MO) no solo, sendo utilizadas, de forma indistinta, soluções densas de iodeto de sódio (NaI) e de politungstato de sódio (PTS).

Impact of Density Gradients and Momentum Ratios on Streamwise Circulation at River Confluences
Water Resources Research, Volume 62, Issue 3, March 2026.Abstract Mixing processes in confluences influence concentrations of water quality parameters such as suspended sediment loads and water chemistry in the post‐confluent reach. Thus, improving our understanding of confluence flow structures and mixing is key to predicting the impact of the downstream propagation of pollutants and nutrients.

Use of densimetric techniques for fractionating soil organic constituents [PDF]
, 1967 Ultrasonic dispersion of soil was used as a pretreatment, prior to densimetric fractionation in a heavy liquid. A 2 to 3 minute sanification period, using a probe type instrument with a 125 watts power output, resulted in maximum recoveries of ...
