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

Method of Ear Detection for Maize Seed Based on Fisher Criterion [PDF]

Xibei Gongye Daxue Xuebao, 2018
The purpose of this paper is to use machine vision to detect the size, shape, texture and color of maize seed ear. The traditional method is very limited and cannot meet the detection efficiency.

Adaptive band selection snapshot multispectral imaging in the VIS/NIR domain

, 2010
Hyperspectral imaging has proven its efficiency for target detection applications but the acquisition mode and the data rate are major issues when dealing with real-time detection applications.

Hematopoietic (stem) cells—The elixir of life?

FEBS Letters, EarlyView.
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Evaluation of the efficiency of detection of bacterial DNA in milk and tissue samples from cattle, sheep, and goats by conventional and nested PCR targeting Com1, sod and Transposase IS1111 genes of Coxiella burnetii genome

Macedonian Veterinary Review
Q fever is a worldwide zoonosis, caused by Coxiella burnetii, an obligate intracellular bacterium that affects both humans and animals. The serious consequences on human health and the economic losses it causes, require the use of rapid, accurate, and ...

High efficiency photon counting using stopped light

, 2002
Single-photon detection and photon counting play a central role in a large number of quantum communication and computation protocols. While the efficiency of state-of-the-art photo-detectors is well below the desired limits, quantum state measurements in

SplitScreen: Enabling efficient, distributed malware detection [PDF]

Journal of Communications and Networks, 2011
We present the design and implementation of a novel anti-malware system called SplitScreen. SplitScreen performs an additional screening step prior to the signature matching phase found in existing approaches. The screening step filters out most non-infected files (90%) and also identifies malware signatures that are not of interest (99%).

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.

Single photon detection performance of highly disordered NbTiN thin films

Journal of Physics Communications, 2023
We experimentally investigated the detection performance of highly disordered ${{\rm{Nb}}}_{x}{{\rm{Ti}}}_{1-x}{\rm{N}}\,$ based superconducting nanowire single photon detectors (SNSPDs).
