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

open access: yesFEBS 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

open access: yesFEBS 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

DGMT: A Fully Dynamic Group Signature from Symmetric-Key Primitives

open access: yesCryptography
A group signature scheme allows a user to sign a message anonymously on behalf of a group and provides accountability by using an opening authority who can “open” a signature and reveal the signer’s identity. Group signature schemes have been widely used

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

open access: yesFEBS 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.

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

open access: yesFEBS 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.

Energy-Preserving/Group-Preserving Schemes for Depicting Nonlinear Vibrations of Multi-Coupled Duffing Oscillators

open access: yesVibration
In the paper, we first develop a novel automatically energy-preserving scheme (AEPS) for the undamped and unforced single and multi-coupled Duffing equations by recasting them to the Lie-type systems of ordinary differential equations.

Group-lending: Sequential financing, lender monitoring and joint liability [PDF]

open access: yes
We develop a simple model of group-lendingbased on peer monitoring and moral hazard. We find that, in the absence of sequential financing or lender monitoring, group-lending schemes may involve under-monitoring with the borrowers investing in undesirable

The role and implications of mammalian cellular circadian entrainment

open access: yesFEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

PKIS: practical keyword index search on cloud datacenter

open access: yesEURASIP Journal on Wireless Communications and Networking, 2011
This paper highlights the importance of the interoperability of the encrypted DB in terms of the characteristics of DB and efficient schemes. Although most prior researches have developed efficient algorithms under the provable security, they do not ...

Antibiotic prophylaxis in prostate biopsy: a comparative randomized clinical assay between ciprofloxacin, norfloxacin and chloramphenicol

open access: yesInternational Brazilian Journal of Urology, 2003
OBJECTIVE: To compare, prospectively, 4 different schemes of antibiotic prophylaxis previously to transrectal prostate biopsy. MATERIALS AND METHODS: 257 patients were randomized in 4 groups: Group I: single dose of ciprofloxacin 2 hours before the ...
