Nature and size of rodent cages vary from one laboratory or country to another. Little is however known about the physiological implications of exposure to diverse cage sizes in animal-based experiments.

Here, two groups of male Swiss mice (Control group - Cage stationed, and Test group - Cage migrated) were used for this study. The cage-migrated mice were exposed daily to various cage sizes used across laboratories in Nigeria while the cage-stationed mice exposed daily to different but the same cage size and shape. At the end of the 30 days exposure, top-rated paradigms were used to profile changes in physiological behaviours, and this was followed by evaluation of histological and biochemical metrics.

The study showed a significant (p < 0.05) decrease in blood glucose levels (at 60 and 120 min of oral glucose tolerance test) in the cage-migrated mice compared to cage-stationed mice. Strikingly, peripheral oxidative stress (plasma malondialdehyde) and pain sensitivity (formalin test, hot-and-cold plse negative/positive results and leading to poor translational outcomes.

Human adenovirus (HAdV) infections are associated with a high morbidity and mortality in transplant patients requiring the use of antiviral treatments. Brincidofovir (BCV), a cytidine analog, inhibits HAdV replication through viral DNA elongation termination and likely through other mechanisms. To elucidate if BCV regulates cellular antiviral pathways, we analyzed its impact on HAdV-infected and non-HAdV-infected lung epithelial cells.

We assessed the cellular and viral transcriptome of A549cells infected and non-infected with HAdV C5 and treated or non-treated with BCV by RNAseq after 72h.

BCV treatment of HAdV infected cells resulted in a profound decrease of viral transcription associated with a relative overexpression of the early genes E1A and E4 and of the late gene L1. BCV had also a profound impact on A549cells' transcriptome. Ontologic analysis revealed an effect of BCV on several pathways known to interact with adenovirus replication as mTor signalling and Wnt pathways. A549 cells treated with BCV demonstrated a significant inhibition of the biological function of "viral replication" including 25 dysregulated genes involved in inflammation pathways.

We demonstrated that BCV alters viral gene expression and promotes the expression of antiviral cellular pathways in A549cells. These results provide new insights how to interfere with cellular pathways to control HAdV infections.

As viruses lack their own glycosylation machinery, they are dependent on the host's machinery for these processes. Certain iminosugars are known to interfere with the N-linked glycosylation pathway by targeting and inhibiting α-glucosidases I and II in the endoplasmic reticulum (ER). Perturbing ER α-glucosidase function can prevent these enzymes from removing terminal glucose residues on N-linked glycans, interrupting the interaction between viral glycoproteins and host chaperone proteins that is necessary for proper folding of the viral protein. Iminosugars have demonstrated broad-spectrum antiviral activity in vitro and in vivo against multiple viruses. This review discusses the broad activity of iminosugars against Flaviviridae. Iminosugars have shown favorable activity against multiple members of the Flaviviridae family in vitro and in murine models of disease, although the activity and mechanism of inhibition can be virus-specfic. While iminosugars are not currently approved for the treatment of viral infections, their potential use as future host-targeted antiviral (HTAV) therapies continues to be investigated.

Heart failure (HF) is the most common complication of patients with atrial fibrillation (AF), but possible risk factors or health consequences are not well described. Low kidney function is a risk factor for both AF and HF. We evaluated estimated glomerular filtration rate (eGFR) as a predictor of HF in patients with AF, and then quantified the adverse health outcomes associated to incident HF.

This is an observational analysis of 19,662 adults without a previous history of HF who had new-onset AF in Stockholm healthcare (Sweden) during 2007-2011. During a median of 713 (IQR 281-1253) days of follow up, 3342 (16.4%) patients developed HF, with incidence rate of 7.4 per 100-person-years (95% CI 7.2-7.7). In Cox regression, eGFR was linearly associated with subsequent HF risk. Choline price Compared to eGFR≥60ml/min/1.73m

had 13% (HR 1.13; 95% CI 1.04-1.23) and 53% (HR 1.53; 1.25-1.88) higher risk of HF. Results were consistent across various pre-specified subgroups and after excluding early events. Compared to non-HF, developing HF (as a time-varying exposure) was associated with a 5-fold (HR 5.05; 4.07-6.28) higher risk of subsequent kidney function decline, a 1.5 times higher risk of stroke (HR 1.54; 1.35-1.76), and a doubling in the risk of myocardial infarction (HR 2.21; 1.87-2.62) and death (HR 2.17; 2.01-2.33).

In patients with AF, low kidney function associates with the risk of HF. Developing HF heightened the subsequent risk of kidney function decline, cardiovascular event and death.

GapmeRs are oligonucleotides that bind to a specific RNA sequence and thereby affecting posttranscriptional gene regulation. They therefore hold the potential to manipulate targets where current pharmacological modulators are inefficient or exhibit adverse side effects. Here, we show that a treatment with a GapmeR, mediating knockdown of small conductance Ca

-activated K

channels (SK3), has an in vivo protective effect against atrial fibrillation (AF) in rats.

A unique SK3-GapmeR design was selected after thorough in vitro evaluation. 22 rats were randomly assigned to receive either 50mg/kg SK3-GapmeR or vehicle subcutaneously once a week for two weeks. Langendorff experiments were performed seven days after the last injection, where action potential duration (APD

), effective refractory period (ERP) and AF propensity were investigated. SK3 channel activity was evaluated using the SK channel blocker, ICA (N-(pyridin-2-yl)-4-(pyridine-2-yl)thiazol-2-amine). SK3 protein expression was assessed by Western Blot.
