Capillary rise in eluvium-deluvial gravelly soil

Shuiwen dizhi gongcheng dizhi
The height of capillary water rise and the associated moisture distribution influence the permeability and strength of capillary zone soils. Accurate determination of the capillary rise height and moisture profile is therefore essential for evaluating ...

Visualization of grout diffusion in coarse-grained materials using transparent soil: Effects of Fine particle content.

PLoS ONE
Fine-particle loss in earth-rock dams can induce abnormal grout diffusion during rehabilitation. To address this issue, we investigated the influence of fine particle content on grouting efficiency in coarse-grained materials.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

PANoptosis in the pathogenesis of myelodysplastic syndromes

Molecular Oncology, EarlyView.
PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...

Impact of Gap-Graded Soil Geometrical Characteristics on Soil Response to Suffusion

Geotechnics
The phenomenon of fine particle migration through the voids of the granule skeleton under the seepage force is called suffusion. Relative density, original fine particle content, and gap ratio are thought to play vital roles in the suffusion process ...

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

FEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...
