Abrasion Resistance of Thermoplastic Polyurethane in Abrasion Resistance Test Using Abrasives.
KOBUNSHI RONBUNSHU, 1992 ポリカプロラクトン, 4, 4'-ジフェニルメタンジイソシアナート, 1, 4-ブタンジオールからなる熱可塑性ポリウレタンのうち組成比の異なる2種類の試料について, 研磨材を用いた摩耗試験を行った. その結果, 硬さが小さく, 動的貯蔵弾性率 (E') の小さい試料が耐摩耗性が良好であった. また, 温度を上げた状態での摩耗試験の結果, 及び加圧下でのポリウレタンと鋼球の接触状態の観察から, E'の低い試料では, 研磨材との接触面積が大きくなり, 研磨材と一体となった層を形成するため, 耐摩耗性が向上するものと考えられた.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics
FEBS Letters, EarlyView.Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

Studying the Morphologic Maturation of Aeolian Sand Grains During Transportation Process of Wind Erosion (Case study: Khartouran Erg) [PDF]
Desert, 2009 Wind, in the duration of its erosional process, affects considerable changes in a grain's morphologyfrom its removal (detachment) step to sedimentation. In other word, a grain undergoes its gradualevolution during the transit process.
