Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

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

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.

Point-shift foliation of a point process

Electronic Journal of Probability, 2018
A point-shift $F$ maps each point of a point process $ $ to some point of $ $. For all translation invariant point-shifts $F$, the $F$-foliation of $ $ is a partition of the support of $ $ which is the discrete analogue of the stable manifold of $F$ on $ $.

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.

Aging Renewal Point Processes and Exchangeability of Event Times

Mathematics
In this paper, we investigate the impact of latency aging on exchangeable (invariant under permutation of indices) inter-arrival times arising from mixed renewal point processes (statistical mixtures of point processes with renewal inter-arrival times ...

Modeling of Cellular Networks Using Stationary and Nonstationary Point Processes

IEEE Access, 2018
The spatial topology of the base stations in wireless networks has a profound impact on their performance evaluation and analysis. It is important to identify a proper and accurate point process model before applying any theoretical stochastic geometry ...

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.

Turning Point Processes to Higher Education among Care Leavers

Social Work and Society, 2014
Children who grew up in care institutions encounter many difficulties in the years after leaving care, including challenges related to their low education achievements while they were still in care. Higher education is therefore hard and sometimes almost

Satistical problems of point processes [PDF]

Mathematica Applicanda, 1978
This is a set of lectures delivered at the International Mathematical Centre, Warsaw, in 1976. The text contains three sections. Section 1 is devoted to basic notions. In the second section inference from a family of Poisson processes is considered. The last section deals with the problems of filtering of Cox processes (doubly stochastic processes).
