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

Attribute-based encryption with hidden policies in the access tree

Tongxin xuebao, 2015
The existing policies-hidden attribute-based encryption (ABE) schemes could only support a limited access structure,which resulted in weak expressiveness.A new structure of access tree was thus proposed to integrate attribute hiding and secret sharing ...

Secret sharing scheme with general access structure based on integer programming [PDF]

Jisuanji gongcheng, 2019
In order to simplify the access structure and ensure that all integer programming have solutions,a scheme is proposed to apply integer programming directly to the secret sharing of general access structure.By constructing integer programming,the secret ...

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.

Reducing The Computational Complexity of Fuzzy Identity-Based Encryption from Lattice [PDF]

International Journal of Information and Communication Technology Research
—In order to provide access control on encrypted data, Attribute-based encryption (ABE) defines each user using a set of attributes. Fuzzy identity-based encryption (FIBE) is a variant of ABE that allows for a threshold access structure for users.

GlycomeDB – integration of open-access carbohydrate structure databases

BMC Bioinformatics, 2008
Background Although carbohydrates are the third major class of biological macromolecules, after proteins and DNA, there is neither a comprehensive database for carbohydrate structures nor an established universal structure encoding scheme for ...

CP-ABE Scheme Based on Prime Group with Fully Hidden Access Structure [PDF]

Jisuanji gongcheng, 2016
Existing Attribute-based Encryption(ABE) schemes with hidden access structures are only partially hidden,which will lead to privacy leaks.Therefore,this paper proposes a Ciphertext-policy Attribute-based Encryption(CP-ABE) scheme with fully hidden access

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
