Pathogenesis of prosthetic joint infections: bacterial adhesion and internalization in osteoblasts, synoviocytes and endothelial cells.

is frequently isolated during prosthetic joint infections (PJIs). Unlike , its internalization and persistence within cells are controversial. We aimed to determine whether internalization is involved in the pathophysiology of PJIs.

: insights into epidemiology, virulence, and antimicrobial resistance of a clinically relevant bacterial species.

SUMMARY is divided into two subspecies, subsp. (renamed in 1992; ATCC 49326) and subsp. (ATCC 27840), and fits with the archetype of clinically relevant coagulase-negative staphylococci (CoNS).

X-rays minibeam radiation therapy at a conventional irradiator: Pilot evaluation in F98-glioma bearing rats and dose calculations in a human phantom.

Minibeam radiation therapy (MBRT) is a type of spatial fractionated radiotherapy that uses submillimetric beams. This work reports on a pilot study on normal tissue response and the increase of the lifespan of glioma-bearing rats when irradiated with a tabletop x-ray system. Our results show a significant widening of the therapeutic window for brain tumours treated with MBRT: an important proportion of long-term survivals (60%) coupled with a significant reduction of toxicity when compared with conventional (broad beam) irradiations.

Spatially Modulated Proton Minibeams Results in the Same Increase of Lifespan as a Uniform Target Dose Coverage in F98-Glioma-Bearing Rats.

Proton minibeam radiation therapy (pMBRT) is a new approach in proton radiotherapy, by which a significant increase in the therapeutic index has already been demonstrated in RG2 glioma-bearing rats. In the current study we investigated the response of other types of glioma (F98) and performed a comparative evaluation of tumor control effectiveness by pMBRT (with different levels of dose heterogeneity) versus conventional proton therapy. The results of our study showed an equivalent increase in the lifespan for all evaluated groups (conventional proton irradiation and pMBRT) and no significant differences in the histopathological analysis of the tumors or remaining brain tissue.

Maternal resistin predisposes offspring to hypothalamic inflammation and body weight gain.

Resistin promotes hypothalamic neuroinflammation and insulin resistance through Toll like receptor 4 (TLR4), this hormone is thought to be a link between obesity and insulin-resistance. Indeed, resistin plasma levels are higher in obese and insulin resistant subjects. However, the impact of maternal resistin on the predisposition of offspring to hypothalamic neuroinflammation is unknown.
