A Dual‐Targeting T6SS DNase Drives Bacterial Antagonism and Eukaryotic Apoptosis via the cGAS‐STING‐TNF Axis

open access: yesAdvanced Science, EarlyView.
The bacterial Type VI secretion system (T6SS) emerges as a sophisticated virulence mechanism, leveraging the dual‐function effector TkeA from Yersinia pseudotuberculosis. TkeA concurrently damages rival bacteria and host cell DNA, triggering the host's cGAS‐STING‐TNF pathway and inducing apoptosis.

Landscape phage, phage display, stripped phage, biosensors, detection, affinity reagent, nanotechnology, Salmonella typhimurium, Bacillus anthracis [PDF]

open access: yesDans European Nano Systems Worshop - ENS 2005, Paris : France (2005), 2007
Filamentous phage, such as fd used in this study, are thread-shaped bacterial viruses. Their outer coat is a tube formed by thousands equal copies of the major coat protein pVIII. We constructed libraries of random peptides fused to all pVIII domains and selected phages that act as probes specific for a panel of test antigens and biological threat ...

High‐Throughput Tiling of Essential mRNAs Increases Potency of Antisense Antibiotics

open access: yesAdvanced Science, EarlyView.
The systematic tiling of essential genes’ mRNA here presented, proposes a valuable tool for the identification of novel PNA sequences with antibiotic potential. The high‐throughput synthetic set up opens the door to investigating thousands of sequences in an economic way and ultimately identifies potent antisense oligonucleotides while also giving room

The SIR model in a moving population: propagation of infection and herd immunity [PDF]

open access: yesarXiv, 2022
In a collection of particles performing independent random walks on $\mathbb Z^d$ we study the spread of an infection with SIR dynamics. Susceptible particles become infected when they meet an infected particle. Infected particles heal and are removed at rate $\nu$.

Precision‐Guided Stealth Missiles in Biomedicine: Biological Carrier‐Mediated Nanomedicine Hitchhiking Strategy

open access: yesAdvanced Science, EarlyView.
Diagram illustrating the binding methods of NPs and biological barriers. The biological carrier‐mediated nanomedicine hitchhiking strategy (BCM‐NHS) utilizes two distinct techniques: the surface‐based “Backpack” method, which relies on ligand‐receptor binding, covalent conjugation, and non‐covalent binding, and the encapsulated “Trojan horse” approach,

Survival of Salmonella spp. in Composting using Vial and Direct Inoculums Technique [PDF]

open access: yesarXiv, 2014
The survival of Salmonella spp. as pathogen indicator in composting was studied. The inoculums technique was used to gives the known amounts of Salmonella spp. involved in composting. The inoculums of Salmonella spp. solution was added directly into the compost material. The direct inoculum was compared with inoculums in vial technique.

Entropy driven formation of a chiral liquid crystalline phase of helical filaments [PDF]

open access: yes, 2005
We study the liquid crystalline phase behavior of a concentrated suspension of helical flagella isolated from {\it Salmonella typhimurium}. Flagella are prepared with different polymorphic states, some of which have a pronounced helical character while others assume a rod-like shape. We show that the static phase behavior and dynamics of chiral helices

A Transcriptome‐Wide Mendelian Randomization Study in Isolated Human Immune Cells Highlights Risk Genes Involved in Viral Infections and Potential Drug Repurposing Opportunities for Schizophrenia

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Schizophrenia is a neurodevelopmental psychiatric disorder characterized by symptoms of psychosis, thought disorder, and flattened affect. Immune mechanisms are associated with schizophrenia, though the precise nature of this relationship (causal, correlated, consequential) and the mechanisms involved are not fully understood.

Disruption of the blood–brain barrier contributes to neurobehavioral changes observed in rheumatic heart disease

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Sydenham's chorea (SC) is the neurological manifestation associated with acute rheumatic fever (ARF), triggered by a group A streptococcal (GAS) infection. Anti‐GAS antibodies cross‐reacting with tissue proteins are implicated in the development of neurological changes. In this study, using an animal model, we demonstrate that a compromised blood–brain

Enumeration of Salmonella in compost material by a non-culture based method [PDF]

open access: yesarXiv, 2014
Accurate enumeration of Salmonella spp. is important for assessing whether this pathogen has survived composting. Recent literature has reported that enumeration of Salmonella spp. using standard microbiological methods has a numbers of disadvantages, particularly the time taken to obtain a result.
