Cerebral microbleeds (CMBs) could contribute to cognitive impairment in the general population and in patients with dementia. We designed a study to (i) develop a murine model of CMBs, (ii) assess whether CMBs affect cognition in this model and (iii) assess whether this model is sensitive to pharmacological modulation. Male C57Bl6/J mice were stereotactically administered collagenase to induce cortical lesion analysed by MRI at 24 h. CMB-mice were assessed at six weeks post-lesion for cognitive performances (Barnes maze and Touchscreen automated paired-associated learning (PAL) task) and for cerebral metabolism (in vivo PET/CT with fluorodeoxyglucose (FDG))...

BACKGROUND & AIMS: There is growing evidence that liver graft ischemia-reperfusion (I/R) is a risk factor for hepatocellular carcinoma (HCC) recurrence, but the involved mechanisms are unclear. Here, we tested the hypothesis that mesenteric congestion due to portal blood flow interruption induces endotoxin-mediated Toll-Like Receptor 4 (Tlr4) engagement, resulting in elevated liver cancer burden. We also assessed the role of remote ischemic preconditioning (RIPC) in this context. METHODS: C57Bl/6j mice were exposed to standardized models of liver I/R injury and RIPC, by occluding hepatic and femoral blood vessels...

Three ruthenium complexes containing a bidentate piq ligand, [(piq)Ru(bpy)2]2+ (1), [(piq)Ru(phen)2]2+ (2), and [(piq)Ru(DIP)2]2+ (3) (piq = phenylisoquinolinate, bpy = 2,2'-bipyridine, phen = 1,10-phenanthroline, DIP = 4,7-diphenyl-1,10-phenanthroline), were prepared. The DNA binding properties of complexes 1-3 to double-stranded DNA were studied. The binding of 1-3 to calf-thymus DNA (ct-DNA) yielded lower emission intensities than those observed with the corresponding Ru complexes alone. To explore potential interactions of complexes 1-3 with lipid-rich organs in live cells, the emission properties of the Ru probes were studied with liposomes...

The dogma that adaptive immunity is the only arm of the immune response with memory capacity has been recently challenged by several studies demonstrating evidence for memory-like innate immune training. However, the underlying mechanisms and location for generating such innate memory responses in vivo remain unknown. Here, we show that access of Bacillus Calmette-Guérin (BCG) to the bone marrow (BM) changes the transcriptional landscape of hematopoietic stem cells (HSCs) and multipotent progenitors (MPPs), leading to local cell expansion and enhanced myelopoiesis at the expense of lymphopoiesis...

The diagnosis of a uterine smooth muscle lesion is, in the majority of cases, straightforward. However, in a small number of cases, the morphological criteria used in such lesions cannot differentiate with certainty a benign from a malignant lesion and a diagnosis of smooth muscle tumor with uncertain malignant potential (STUMP) is made. Uterine leiomyosarcomas are often easy to diagnose but it is difficult or even impossible to identify a prognostic factor at the moment of the diagnosis with the exception of the stage...

Transperineal template prostate biopsies (TTPB) are performed for assessments after unexpected negative transrectal ultrasound biopsies (TRUSB), correlation with imaging findings and during active surveillance. The impact of TTPBs on pathology has not been analysed. The European Network of Uropathology (ENUP) distributed a survey on TTPB, including how specimens were received, processed and analysed. Two hundred forty-four replies were received from 22 countries with TTPBs seen by 68.4% of the responders (n = 167)...

During development, cell numbers are tightly regulated, ensuring that tissues and organs reach their correct size and shape. Recent evidence has highlighted the intricate connections between the cytoskeleton and the regulation of the key growth control Hippo pathway. Looking for apical scaffolds regulating tissue growth, we describe that Drosophila melanogaster big bang (Bbg), a poorly characterized multi-PDZ scaffold, controls epithelial tissue growth without affecting epithelial polarity and architecture...

The bacterial type VI secretion system (T6SS) is a nanomachine that delivers toxic effector proteins into target cells, killing them. In mice, we found that the Vibrio cholerae T6SS attacks members of the host commensal microbiota in vivo, facilitating the pathogen's colonization of the gut. This microbial antagonistic interaction drives measurable changes in the pathogenicity of V. cholerae through enhanced intestinal colonization, expression of bacterial virulence genes, and activation of host innate immune genes...

This pilot study pursued three objectives: to assess the effect of a 1-month multilevel intervention on the PA of children, to assess the impact of the intervention on the theory of planned behavior (TPB) variables, and to evaluate the extent to which the impact of the intervention on PA and TPB variables varied according to personal (i.e., gender and age) and situational (i.e., class and school) moderating variables. Children were aged 7 to 11 years ( n = 306). Analyses revealed a significant increase of PA practice and TPB variables ( ps < ...

Skin lighteners and hair relaxers, both common among women of African descent, have been suggested as possibly affecting breast cancer risk. In Accra and Kumasi, Ghana, we collected detailed information on usage patterns of both exposures among 1,131 invasive breast cancer cases and 2,106 population-controls. Multivariate analyses estimated odds ratios (OR) and 95% confidence intervals (CIs) after adjustment for breast cancer risk factors. Control usage was 25.8% for ever use of skin lighteners and 90.0% for use of hair relaxers for >1 year...

The Escherichia coli SMC complex, MukBEF, acts in chromosome segregation. MukBEF shares the distinctive architecture of other SMC complexes, with one prominent difference; unlike other kleisins, MukF forms dimers through its N-terminal domain. We show that a 4-helix bundle adjacent to the MukF dimerization domain interacts functionally with the MukB coiled-coiled 'neck' adjacent to the ATPase head. We propose that this interaction leads to an asymmetric tripartite complex, as in other SMC complexes. Since MukF dimerization is preserved during this interaction, MukF directs the formation of dimer of dimer MukBEF complexes, observed previously in vivo...

INTRODUCTION: Hypertensive disorder in pregnancy (HDP) represents the most common medical complication in pregnancy. It is the leading cause of maternal and perinatal mortality and morbidity. Vascular endothelial growth factor (VEGF) stimulates vascular endothelial cell growth, survival, and proliferation, and they are known to be expressed in human placenta. The aim of this study was to determine the VEGF expression in the placenta of hypertensive and normotensive patients. MATERIALS AND METHODS: This is a retrospective, cross-sectional study from January 1, 2015 to December 31, 2015...

Mesenchymal stem cell therapy is a promising treatment for perianal Crohn's fistulas refractory to conventional therapy, which are an extremely morbid complication and a true therapeutic challenge. Autologous adipose-derived stromal vascular fraction (ADSVF) is an easily accessible source of cells with angiogenic, anti-inflammatory, immunomodulatory, and regenerative properties. Here, we describe a case involving a patient with severe perianal Crohn's fistulas refractory to the best medical and surgical practices who received local treatment with ADSVF and microfat...

Ibrutinib is indicated in Europe for the treatment of several B-cell malignancies, including chronic lymphocytic leukaemia (CLL). However, despite the high efficacy and favourable toxicity profile of ibrutinib, recent data suggest that it is not always administered optimally in clinical practice, with an increased tendency for dose reduction and a higher frequency of discontinuation. An expert panel of European haematologists was convened to identify practical issues pertinent to physicians involved in the therapeutic management of ibrutinib-treated CLL patients and here we outline the findings...
