The direct electrochemical carboxylation of aryl, benzyl and alkyl halides by CO is described using a magnesium anode and a nickel foam cathode in an undivided cell. The process employs a sacrificial anode and does not require the additional use of a transition metal catalyst or demanding conditions, as the reactions are carried out under galvanostatic mode, at -10 °C and with commercial DMF. Under these operationally simple conditions, an important range of carboxylic acids are affordable.

Computed tomographic features of clinically suspected rhinitis in domestic rabbits (Oryctolagus cuniculus).

Vet Rec

January 2025

Department of Small Animals Diagnostic Imaging, École Nationale Vétérinaire d'Alfort, Maisons-Alfort, France.

Background: The aim of this study was to characterise the computed tomographic (CT) findings in domestic rabbits with clinically suspected rhinitis and compare them with CT findings in rabbits without clinical signs of rhinitis.

Methods: CT images of rabbits that underwent a CT of the head were retrospectively reviewed and any CT abnormalities were described. Statistical analysis was performed to detect any association between the CT findings and clinical signs of rhinitis, and also to assess if there was any association between rhinitis and otitis media, otitis externa or dental disease.

Periodontitis, a prevalent and costly oral disease, remains incompletely understood in its etiopathogenesis. The conventional model attributes it to pathogenic bacteria, but emerging evidence suggests dysbiosis involving bacteria, herpesviruses, and an exaggerated host immune response. Among herpesviruses, Epstein-Barr virus (EBV) closely links to severe periodontitis, yet the mechanisms underlying EBV-related pathogenesis remain elusive.

Background: In infected hosts, immune responses trigger a systemic energy reallocation away from energy storage and growth, to fuel a costly defense program. The exact energy costs of immune defense are however unknown in general. Life history theory predicts that such costs underpin trade-offs between host disease resistance and other fitness related traits, yet this has been seldom assessed.

Templates for the acquisition of large datasets such as the Human Connectome Project guide the neuroimaging community to reproducible data acquisition and scientific rigor. By contrast, small animal neuroimaging often relies on laboratory-specific protocols, which limit cross-study comparisons. The establishment of broadly validated protocols may facilitate the acquisition of large datasets, which are essential for uncovering potentially small effects often seen in functional MRI (fMRI) studies.
