By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Phase Retrieval of One-Dimensional Objects by the Multiple-Plane Gerchberg–Saxton Algorithm Implemented into a Digital Signal Processor

Optics
In the current study, we address the phase retrieval of one-dimensional phase objects from near-field diffraction patterns using the multiple-plane Gerchberg–Saxton algorithm, which is still widely used for phase retrieval.

m-FISH analysis reveals complexity of chromosome aberrations in individuals occupationally exposed with internal plutonium: A pilot study to assess the relevance of complex aberrations as biomarkers of exposure to high-LET α particles [PDF]

, 2005
We recently demonstrated that a significant proportion of apparently stable insertions induced after exposure to a mean of 1 α particle/cell, detected using 3-colour FISH, were part of larger unstable complexes when visualised by 24-colour FISH ...

Correction of concentrated and distributed aberrations in medical ultrasound imaging [PDF]

, 1996
A method is presented for iterative correction of wave fields aberrated in a plane located at an arbitrary distance from an array transducer. The signals received from the transducer are processed by an inverse extrapolator in such a way that the output ...

The effect of wavefront aberrations in atom interferometry [PDF]

, 2014
Wavefront aberrations are one of the largest uncertainty factors in present atom interferometers. We present a detailed numerical and experimental analysis of this effect based on measured aberrations from optical windows.

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

FEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

The Caenorhabditis elegans DPF‐3 and human DPP4 have tripeptidyl peptidase activity

FEBS Letters, EarlyView.
The dipeptidyl peptidase IV (DPPIV) family comprises serine proteases classically defined by their ability to remove dipeptides from the N‐termini of substrates, a feature that gave the family its name. Here, we report the discovery of a previously unrecognized tripeptidyl peptidase activity in DPPIV family members from two different species.
