Widespread phages of endosymbionts: Phage WO genomics and the proposed taxonomic classification of Symbioviridae.

open access: yesPLoS Genetics, 2022
Wolbachia are the most common obligate, intracellular bacteria in animals. They exist worldwide in arthropod and nematode hosts in which they commonly act as reproductive parasites or mutualists, respectively. Bacteriophage WO, the largest of Wolbachia's

An Outbreak of Severe Infections with Community-Acquired MRSA Carrying the Panton-Valentine Leukocidin Following Vaccination

open access: yes, 2007
Background: Infections with community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) are emerging worldwide. We investigated an outbreak of severe CA-MRSA infections in children following out-patient vaccination. Methods and Findings:

Protein Disulfide Isomerase Disassembles TDP‐43/G3BP1 Condensates and Antagonizes TDP‐43 Pathological Aggregates

open access: yesAdvanced Science, EarlyView.
Cytoplasmic aggregation of TDP‐43 is a common pathological feature in amyotrophic lateral sclerosis, frontotemporal lobar degeneration, and Alzheimer's disease with TDP‐43 pathology. This study reports that wild‐type PDI slows down phase separation of TDP‐43 through direct interaction with TDP‐43.

Transcription Factor Promiscuity Drives Regulatory Rewiring and Evolvability in Gene Networks in Bacteria

open access: yesAdvanced Science, EarlyView.
When a master transcription factor (TF) is lost, bacteria can rapidly rewire gene regulatory networks by co‐opting related regulators. Using experimental evolution in Pseudomonas fluorescens, we show that TF promiscuity (low‐level, non‐cognate binding) provides the raw material for rewiring. Successful co‐option follows a predictable hierarchy governed

Bacteriophage Typing of Bacteriuric Escherichia coli.

open access: yesExperimental Biology and Medicine, 1966
SummaryA bacteriophage typing method of identifying strains of E. coli found in urinary tract infections has been developed. Eight phages were isolated from sewage and used to classify E. coli into 14 phage types. Certain types were found to cause a majority of the infections.

DNA Replication Errors Drive Genome‐Wide Small Inverted Triplication Dynamics

open access: yesAdvanced Science, EarlyView.
This study provides insight into the dynamic equilibrium mechanism of a novel structural variant, small inverted triplication (SIT), which is generated by misalignment of the 3’ flap generated under DNA replication stress with palindromic sequence. Alternatively, the end sequence may fold back on itself to form an inverted fragment.

Selective Inhibition of Integrin β3 Topology Provides a Safer Antithrombotic Strategy

open access: yesAdvanced Science, EarlyView.
Current integrin αIIbβ3 inhibitors effectively reduce thrombosis but also increase bleeding risk. During thrombosis, high shear blood flow can directly activate the integrin αIIbβ3 via a distinct topological change in the β3 transmembrane domain, independent of hemostatic platelet signaling.

Comparative genomic analysis of clinical strains of Campylobacter jejuni from South Africa.

open access: yesPLoS ONE, 2008
BackgroundCampylobacter jejuni is a common cause of acute gastroenteritis and is also associated with the post-infectious neuropathies, Guillain-Barré and Miller Fisher syndromes. In the Cape Town area of South Africa, C.

The Development and Pilot Clinical Study of CD147 Targeted Antagonistic Peptide Probe for Tumor Imaging

open access: yesAdvanced Science, EarlyView.
This study establishes [68Ga]Ga‐DOTA‐AP9 as a first‐in‐human CD147‐targeted PET tracer with favorable safety and specific tumor uptake. Tracer accumulation correlates with CD147 expression in patients, enabling noninvasive quantification of CD147‐positive malignancies.
