sp. nov., a novel yeast species isolated from plant leaves in China.

Two novel yeast strains, NYNU 236247 and NYNU 23523, were isolated from the leaves of Hance, collected in the Tianchi Mountain National Forest Park, Henan Province, central China. Phylogenetic analysis of the D1/D2 domain of the large subunit rRNA gene and the internal transcribed spacer (ITS) region revealed the closest relatives of the strains are three described species: , and . The novel species differed from the type strains of these three species by 12 to 22 nucleotide substitutions and 1 gap (~2.

A Novel Dynamic Growth Rod Inducing Spinal Growth Modulation for the Correction of Spinal Deformities.

Background: Growth rods are the gold standard for treating early-onset scoliosis (EOS). However, current treatments with growth rods do not optimize spinal growth in EOS patients, and frequent distraction surgeries significantly increase complications, imposing considerable economic and psychological burdens on patients. An improved growth rod is urgently required to address the need for dynamic growth and external regulation.

Abrasive Wear Performance of Spherical Hierarchical Structured TiC/High-Manganese Steel Composites.

The abrasive wear performance of TiC particle-reinforced high-manganese steel matrix composites with a spherical hierarchical structure under moderate impact energy was investigated. In the composites, TiC particles (10 μm in diameter) were concentrated within discrete spherical composite regions with diameters of about 100 μm. Impact abrasive wear tests were conducted to evaluate the wear performance of the composites with different volume fractions (30%, 40%, and 50%) of TiC particles compared with the matrix and a uniformly distributed TiC particle composite.

3,4-dimethylpyrazole phosphate (DMPP) may negate the expected stimulation of elevated atmospheric CO and warming in fertilizer-N loss.

People have accepted the clear fact that elevated CO (eCO) and climate warming are happening, but sustainable agricultural systems are still struggling to adapt. 3,4-dimethyl-1H-pyrazol phosphate (DMPP) is currently recognized as a highly effective strategy for reducing nitrogen (N) loss and related environmental impacts. There is still uncertainty, however, whether DMPP could contribute to building climate-resilient ecosystems in a future climate scenario with co-elevated CO and temperature.
