Polyphyletic Nature of Salmonella enterica Serotype Derby and Lineage-Specific Host-Association Revealed by Genome-Wide Analysis

open access: yesFrontiers in Microbiology, 2018
In France, Salmonella Derby is one of the most prevalent serotypes in pork and poultry meat. Since 2006, it has ranked among the 10 most frequent Salmonella serotypes isolated in humans.

Effect of electroacupuncture on glial fibrillary acidic protein and nerve growth factor in the hippocampus of rats with hyperlipidemia and middle cerebral artery thrombus

open access: yesNeural Regeneration Research, 2021
Electroacupuncture (EA) has been shown to reduce blood lipid level and improve cerebral ischemia in rats with hyperlipemia complicated by cerebral ischemia. However, there are few studies on the results and mechanism of the effect of EA in reducing blood

Neutral particle analyzer for plasma diagnostics on tokamak ST40

open access: yesReview of Scientific Instruments
A neutral particle analyzer was designed and implemented for plasma diagnostics on the spherical tokamak ST40. The diagnostic aims to measure both the bulk ion temperature (0.5–10 keV) and the energy distribution of fast ions generated by a neutral beam injection (up to 40 keV).

Faster fusion: ST40, engineering, commissioning, first results [PDF]

open access: yesAIP Conference Proceedings, 2019
Spherical Tokamak (ST) path to Fusion has been proposed [1] and experiments on STs demonstrated feasibility of this approach. Advances in High Temperature Superconductor technology [2] allows significant increase in the toroidal field (TF) which was found to improve confinement in STs.

Interplay between beam-driven chirping modes and plasma confinement transitions in spherical tokamak ST40

open access: yesNuclear Fusion, 2022
Experiments on the high field spherical tokamak ST40 have led to the recent observation of interplay between beam-driven modes of sweeping frequency (chirping modes) and transitions to the enhanced global confinement regime (H-mode) and back to the low ...

Multidrug‐Resistant Pathogen Clonal Spread in Nigeria: A Systematic Review and Meta‐Analysis

open access: yesHealth Science Reports, Volume 9, Issue 3, March 2026.
ABSTRACT Background and Aim The rapid dissemination of multidrug‐resistant (MDR) bacterial clones poses a global health threat and limits treatment options. Understanding the dynamics of bacterial clones in Nigeria is essential for developing effective control strategies. This systematic review aimed to track MDR pathogen clones in Nigeria. Methods The

Escaping Constraints to Innovate: Maternal Neofunctionalization in a HoxB4 Duplicate

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 2, Page 141-151, March 2026.
Whole‐genome duplication in Xenopus laevis generated duplicated Hox genes that are largely constrained in sequence and developmental expression. However, HoxB4L uniquely acquired maternal expression through cis‐regulatory and protein structural divergence, illustrating how gene duplication enables transcription factors to escape pleiotropic constraints
