Some results on C-normal operators [PDF]

Surveys in Mathematics and its Applications, 2023
A bounded linear operator on a complex Hilbert space ℋ is a C-normal operator if there exists a conjugation C on ℋ such that CT* TC=TT* . This class of operators seems a natural generalization of C-symmetric operators on a Hilbert space.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Nucleic Acid Carriers Based on Precise Polymer Conjugates [PDF]

, 2011
Polymer polydispersity, random conjugation of functional groups, and poorly understood structure–activity relationships have constantly hampered progress in the development of nucleic acid carriers.

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

FEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Compression and broadening of phase-conjugate pulses in photorefractive self-pumped phase conjugator

, 2000
Pulse propagation and shaping are investigated in photorefractive self-pumped phase conjugators in both transmission- and reflection-grating regimes. The dispersion properties of self-pumped phase conjugators are analyzed by taking into account both the ...

A method for separation of classes of linear conjugation problems for three-dimensional vector

, 2020
© 2015, Allerton Press, Inc. We consider structure of the set of piecewise-meromorphic solutions of the homogeneouslinear conjugation problems for three-dimensional vector, and study their relations with a system of two problems of fractional-linear ...

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

FEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Ultrasound-assisted tannic acid crosslinking of myofibrillar protein-stabilized high internal phase emulsions: Enhanced stability, mechanical properties, and 3D printability

Ultrasonics Sonochemistry
The study investigated the synergistic effects of high ultrasound (HS) treatment and tannic acid (TA) conjugation on the structural and interfacial properties of myofibrillar protein (MP), and their roles in stabilizing high internal phase emulsions ...
