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 ...

Assessing particle count in electron microscopy measurements of nanomaterials to support regulatory guidance

Scientific Reports
In the European Union, nanomaterials are regulated through different pieces of sectoral legislation. This legislation often requires risk assessments and thus reliable characterization data, for which regulatory guidance generally recommend electron ...

Study on the relationship of continuous laser printing and the distance of trace on the OPC

Journal of Forensic Science and Medicine, 2017
This thesis aims to seek the relationship between photosensitive drum cyclical trace distance of two pages (shorted for L') and continuity printing of laser printers. Characteristics quantification, statistics are chosen to evaluate the data and results.

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 ...

Postcards from Chile and Images from an Archive: Lighting the Nitrate of the 1973 Coup

Humanities, 2018
This article examines a mass produced postcard image as a picture of conflict. It considers the postcard as a Benjaminian ‘prismatic fringe’ through which an archive can be viewed, wherein documents of the British trade in Chilean nitrate are

Event-related brain potential correlates of human auditory sensory memory-trace formation [PDF]

, 2005
The event-related potential (ERP) component mismatch negativity (MMN) is a neural marker of human echoic memory. MMN is elicited by deviant sounds embedded in a stream of frequent standards, reflecting the deviation from an inferred memory trace of the ...

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Model-Based Trace-Checking

, 2003
Trace analysis can be a useful way to discover problems in a program under test. Rather than writing a special purpose trace analysis tool, this paper proposes that traces can usefully be analysed by checking them against a formal model using a standard ...
