Structural and Biochemical Analysis of OrfG: The VirB8-like Component of the Conjugative Type IV Secretion System of ICESt3 From Streptococcus thermophilus

open access: yesFrontiers in Molecular Biosciences, 2021
Conjugative transfer is a major threat to global health since it contributes to the spread of antibiotic resistance genes and virulence factors among commensal and pathogenic bacteria.

Conjugate DNAzymes [PDF]

open access: yesNucleic Acids Symposium Series, 2003
Conjugate DNAzymes were synthesized by solid phase fragment condensation and their biological properties were characterized. They have increased affinity to target RNA, enhanced stability against DNase 1 digestion and comparable or higher RNA cleaving activity compared with native and also phosphorothioate DNA zymes.

Conjugation on reddening sequences and conjugation difference

open access: yesJournal of Algebra
We describe the conjugation of the reddening sequence according to the formula of $c$-vectors with respect to changing the initial seed. As applications, we extend the Rotation Lemma, the Target before Source Theorem, and the mutation invariant property of the existence of reddening sequences to totally sign-skew-symmetric cluster algebras. Furthermore,

Capture of mobile genetic elements following intercellular conjugation promotes the production of ST11-KL64 CR-hvKP

open access: yesMicrobiology Spectrum
Sequence type (ST)11 carbapenem-resistant hypervirulent Klebsiella pneumoniae (CR-hvKP) can cause life-threatening infections and is therefore of global concern.

Deep-tissue focal fluorescence imaging with digitally time-reversed ultrasound-encoded light. [PDF]

open access: yes, 2012
Fluorescence imaging is one of the most important research tools in biomedical sciences. However, scattering of light severely impedes imaging of thick biological samples beyond the ballistic regime.

Variation on a theme; an overview of the Tn916 / Tn1545 family of mobile genetic elements in the oral and nasopharyngeal streptococci.

open access: yesFrontiers in Microbiology, 2014
The oral and nasopharyngeal streptococci are a major part of the normal microbiota in humans. Most human associated streptococci are considered commensals however a small number of them are pathogenic, causing a wide range of diseases including oral ...

Folic acid conjugated with serum albumin for nano- and submicron delivery systems for applications in therapy and diagnostics [PDF]

open access: yesExploration of Drug Science
Folic acid (FA) residue is a well-known and widely spread targeting ligand, or biovector, used as a component in engineering artificial nanosized and submicron particles (NSPs) to target various cells and treat a variety of diseases that are associated ...

Dominant Bacterial Phyla from the Human Gut Show Widespread Ability To Transform and Conjugate Bile Acids

open access: yesmSystems, 2021
Gut bacteria influence human physiology by chemically modifying host-synthesized primary bile acids. These modified bile acids, known as secondary bile acids, can act as signaling molecules that modulate host lipid, glucose, and energy metabolism and ...

Conjugate Jacobi Series and Conjugate Functions

open access: yesJournal of Approximation Theory, 1996
The starting point is the notion of conjugacy on a Euclidean \(n\)-space as defined by \textit{E. M. Stein} and \textit{G. Weiss} [Acta Math. 103, 25-62 (1962; Zbl 0097.28501)]. Conjugate Jacobi series is introduced in the sense that the Jacobi harmonic function and the conjugate harmonic function (indicated in the title) satisfy the generalized Cauchy-

A broad brush, global overview of bacterial sexuality [PDF]

open access: yes, 2011
Bacterial sexuality is confusing, even for experts! I used to be such an expert on one mechanism of sexuality, conjugation, but that was over 30 years ago.
