Controls on spatial and temporal variations in sand delivery to salmonid spawning riffles [PDF]

, 2017
Fine sediment infiltration into gravel interstices is known to be detrimental to incubating salmonid embryos. Infiltration into spawning riffles can show large spatial variations at the scale of a morphological unit and over time, with significant ...

Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Microstructure and properties of W–Cu composites reinforced by in-situ synthesized WC particles in surface layer

Journal of Materials Research and Technology
In the present work, cast iron was used as the carbon source to fabricate WC particle gradient-reinforced W–Cu composites. The results revealed that the surface layer of W–Cu composites after carbonization can be divided into a complete carbonization ...

Mitochondrial fission-induced mtDNA stress promotes tumor-associated macrophage infiltration and HCC progression

Oncogene, 2019
Tumor-associated macrophages (TAMs) contribute to hepatocellular carcinoma (HCC) progression. However, the molecular mechanism underlying the infiltration of TAMs into HCC microenvironment is largely unclear.

Single‐cell RNA sequencing and lipidomics reveal cell and lipid dynamics of fat infiltration in skeletal muscle

Journal of Cachexia, Sarcopenia and Muscle, 2020
Ageing is accompanied by sarcopenia and intramuscular fat (IMAT) infiltration. In skeletal muscle, fat infiltration is a common feature in several myopathies and is associated with muscular dysfunction and insulin resistance. However, the cellular origin

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.
