The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Influences on Bottom Hole Pressure in Riserless Drilling under Platform Disturbance

Shiyou jixie, 2022
In order to solve the problem of bottom hole pressure fluctuation caused by drilling platform disturbance in riserless drilling,a mathematical model for platform-drill string coupling vibration and a model for bottom hole pressure fluctuation were ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Numerical Calculation of the Influence of Working Conditions and Rotational Speed on Pressure Pulsation of a Self‐Priming Pump

Energy Science & Engineering
To accurately determine the pressure fluctuation characteristics of a specific self‐priming pump, a full three‐dimensional computational model was established, including the S‐tube, impeller domain, volute domain, gas‐liquid separation chamber, front and

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Detecting Pressure Waves during Earthquakes in an In-Service Pipeline System for Agricultural Irrigation using Numerical Analysis

e-Journal of Nondestructive Testing
Seismic hydrodynamic pressure, which is burst water pressure fluctuation induced by earthquakes, is often observed in water pipelines. The earthquake damage includes detachment and damage to pneumatic valves in curved pipe sections, and we believe that ...

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

FEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified
