From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS 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 ...

Differential Pressure Transmitters, Span-Shift Errors With Static Pressure

open access: yes, 1972
The author reviews methods of calibrating low-differential (25–300 in. H2O) D.P. transmitters at high (up to 3000 psig) static pressure. Various test methods are described along with discussion of their merits.

On Characteristics of Velocity and Pressure Field in Two-Dimensional Turbulent Jet

open access: yesJournal of Fluid Science and Technology, 2007
Fluctuating static pressure is closely related with fluctuating velocity in a turbulent flow, and it plays an important role in the energy balance and anisotropy of turbulence.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS 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.

Design by analysis of ductile failure and buckling in torispherical pressure vessel heads

open access: yes, 2007
Thin shell torispherical pressure vessel heads are known to exhibit complex elastic-plastic deformation and buckling behaviour under static pressure. In pressure vessel Design by Analysis, the designer is required to assess both of these behaviour modes ...

Phase Averaged Static Pressure Fields Inside a Rotating Detonation Combustor

open access: yes, 2022
RDCs have received considerable attention, however experimental measurements of the static pressure field in the combustor are difficult. It is necessary to develop a measurement technique to preserve the sensor while providing a temporally resolved ...

On Static Pressure Fluctuation between Sirocco Fan Blades in a Car Air-Conditioning System

open access: yesJournal of Fluid Science and Technology, 2008
In this study, special attention is directed to static pressure fluctuation in a sirocco fan for a car air-conditioning system, because it is expected that there is a close connection between the fluid noise and the pressure fluctuation.

Mixed‐class J‐domain protein scaffolds promote expanded aggregate handling and multivalent Hsp70 engagement during functional disaggregase assembly

open access: yesFEBS Letters, EarlyView.
Protein aggregates threaten proteostasis and cell health. In human cells, Hsp70–J‐domain protein‐based disaggregases remove aggregates, but how they assemble remains unclear. Our biochemical findings show that DNAJA2‐ and DNAJB1‐containing disaggregase scaffolds enhance luciferase aggregate targeting, and that Hsp70 recruitment by both J‐domain ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS 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 ...
