Retrovirus molecular conjugates [PDF]

open access: yesCellular and Molecular Life Sciences (CMLS), 2001
Retrovirus-derived vectors are currently the preferred vectors used for human gene therapy protocols. Serious safety concerns persist, however, which are specifically related to the formation of a replication-competent virus, and no synthesis method currently employed precludes its formation with certainty.

The Type IV Secretion System of ICEAfe1: Formation of a Conjugative Pilus in Acidithiobacillus ferrooxidans

open access: yesFrontiers in Microbiology, 2019
The dispersal of mobile genetic elements and their gene cargo relies on type IV secretion systems (T4SS). In this work the ICEAfe1 Tra-type T4SS nanomachine, encoded in the publicly available genome of Acidithiobacillus ferrooxidans ATCC 23270TY, was ...

Direct Conjugation of Resveratrol on Hydrophilic Gold Nanoparticles: Structural and Cytotoxic Studies for Biomedical Applications

open access: yesNanomaterials, 2020
Strongly hydrophilic gold nanoparticles (AuNPs), functionalized with citrate and L-cysteine, were synthetized and used as Resveratrol (RSV) vehicle to improve its bioavailability.

Characterizing conjugative plasmids from an antibiotic-resistant dataset for use as broad-host delivery vectors

open access: yesFrontiers in Microbiology, 2023
Human microbiome engineering is increasingly proposed as a way to modulate health outcomes. However, one of the current limitations to engineering microbial communities in situ is delivery of a genetic payload for introducing or modifying genes.

Steenrod squares on conjugation spaces [PDF]

open access: yes, 2005
We prove that the coefficients of the so-called conjugation equation for conjugation spaces in the sense of Hausmann-Holm-Puppe are completely determined by Steenrod squares. This generalises a result of V.A.

Authentication from matrix conjugation [PDF]

open access: yes, 2009
We propose an authentication scheme where forgery (a.k.a. impersonation) seems infeasible without finding the prover's long-term private key. The latter would follow from solving the conjugacy search problem in the platform (noncommutative) semigroup, i ...

A purple odyssey: synthesis and structure of 3-amino-4-hydroxy-6-oxocyclohexa-2,4-dien-1-iminium chloride monohydrate

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2016
In the cation of the title hydrated molecular salt, C6H7N2O2+·Cl−·H2O, the six-membered ring shows unequal bond lengths consistent with delocalization of electrons over two separate 6π systems with single bonds between them.

Conjugation of injections by permutations [PDF]

open access: yes, 2010
Let X be a countably infinite set, and let f, g, and h be any three injective self-maps of X, each having at least one infinite cycle. (For instance, this holds if f, g, and h are not bijections.) We show that there are permutations a and b of X such ...

Differential Requirement for the Cell Wall Integrity Sensor Wsc1p in Diploids Versus Haploids

open access: yesJournal of Fungi, 2021
The primary role of the Cell Wall Integrity Pathway (CWI) in Saccharomyces cerevisiae is monitoring the state of the cell wall in response to general life cycle stresses (growth and mating) and imposed stresses (temperature changes and chemicals). Of the

Implementation of a digital optical phase conjugation system and its application to study the robustness of turbidity suppression by phase conjugation [PDF]

open access: yes, 2010
In this work, we report a novel high capacity (number of degrees of freedom) open loop adaptive optics method, termed digital optical phase conjugation (DOPC), which provides a robust optoelectronic optical phase conjugation (OPC) solution.
