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.

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.

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 ...

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 ...

Solid Pseudopapillary Neoplasm of the Pancreas in Children and Adolescents: Expert Recommendations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare low‐grade malignant exocrine pancreatic tumor, mostly discovered during the second decade of life in females, with a very good prognosis, provided microscopically complete surgical excision is achieved.

A Polymorphic Gene within the Mycobacterium smegmatis esx1 Locus Determines Mycobacterial Self-Identity and Conjugal Compatibility

open access: yesmBio, 2022
Mycobacteria mediate horizontal gene transfer (HGT) by a process called distributive conjugal transfer (DCT) that is mechanistically distinct from oriT-mediated plasmid transfer.

Photoreversible Ultrafast Dynamics of Ring Opening and Increased Conjugation under Spatial Confinement [PDF]

open access: yes, 2023
Isomerization through stereochemical changes and modulation in bond order conjugation are processes that occur ubiquitously in diverse chemical systems and for pho- tochromic spirocompounds, it imparts them their functionality as phototransformable ...

Global Efforts to Reduce Paediatric Cancer Care Disparities in Radiotherapy: A Decade Change

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background We present an update on the status, needs and challenges faced by paediatric imaging and radiotherapy (RT) programmes globally after a previous survey conducted by the International Atomic Energy Agency (IAEA) 10 years prior. Methods We developed and distributed a 121‐question survey to radiation oncologists, medical physicists and ...

Conjugation-Driven “Reverse Mars–van Krevelen”-Type Radical Mechanism for Low-Temperature C–O Bond Activation

open access: yes, 2016
C–O bond activation on monofunctional catalysts (metals, carbides, and oxides) is challenging due to activity constraints imposed by energy scaling relationships.
