Manual versus reciprocating endodontic debridement of equine cheek teeth: Micro-computed tomography findings.
Equine Vet J
December 2024
Department of Large Animal Surgery, Anaesthesia and Orthopaedics, Faculty of Veterinary Medicine, Ghent University, Ghent, Belgium.
Background: In orthograde endodontic treatments, different methods are available to debride the pulp canals of endodontically compromised equine cheek teeth, but their efficacy is unknown.
Objectives: To explore and compare the efficacy and anatomical changes caused by manual versus reciprocating filing techniques in equine cheek teeth, to explore the presence of instrumentation mishaps described in human dentistry and to explore anatomical complexities of the pulp cavity that often remain uninstrumented using microcomputed tomography (μCT).
Study Design: Ex-vivo randomised experiments.
Nicotine increases hepatocyte transthyretin turnover: a possible mechanism for the protective effect of smoking on preeclampsia?

Transthyretin is a thyroid hormone binding protein with a major role in the distribution of thyroid hormones to peripheral tissues. In preeclampsia, the failing placenta releases soluble endoglin into the maternal circulation causing systemic vascular dysfunction. Our group has previously shown that transthyretin binds to soluble endoglin and is taken up as a complex into hepatocytes.

December 2024
Praxis Prenzlauer Berg, Berlin, Germany.
Objectives: The cell wall-less species Mycoplasma genitalium is a sexually transmitted pathogen with strong tendency to acquire resistance. Current knowledge about trends of resistance rates and differences between the risk population of men who have sex with men (MSM) and heterosexual patients as well as about circulating genotypes in both groups is limited.
Methods: Between August 2017 and December 2023, M.

Species relationships and speciation have traditionally been represented by phylogenetic trees, but not all evolutionary histories fit into bifurcating divergence models. Introgressive hybridization challenges this assumption by sometimes [or maybe often] leading to mitochondrial introgression, wherein one species' mitochondrial genome is entirely replaced by another's (mitochondrial capture). Such processes result in mitonuclear discrepancies, complicating species delimitation and phylogenetic inference.

Guangdong Engineering Research Center of High-Value Utilization and Equipment Development of Marine Biological Resources, Southern Marine Science and Engineering Guangdong Laboratory (Guangzhou), Guangzhou, Guangdong, 511458, China. Electronic address:
Carrageenan oligosaccharides have attracted significant attention due to their excellent biological activities, and they can be produced by carrageenases. In this study, a novel marine bacterium, Shewanella sp. LE8, was used to enzymatically degrade carrageenan, and the κ-, ι-, and λ-carrageenases produced by the bacterium were characterized.
