One of the severe complications following traumatic brain injury (TBI) is cerebral edema and its effective treatment is of great interest to prevent further brain damage. This study investigated the effects of minocycline, known for its anti-inflammatory properties, on cerebral edema and its respective inflammatory markers by comparing different dose(More)
Traumatic brain injury (TBI) evokes an intense neuroinflammatory reaction that is essentially mediated by activated microglia and that has been reported to act as a secondary injury mechanism that further promotes neuronal death. It involves the excessive production of inflammatory cytokines and the diminution of neuroprotective and neurotrophic factors,(More)
BACKGROUND As all anticoagulants, apixaban exposes to a bleeding risk, thus an effective way to reverse its effects is needed. Objectives were to study efficacy and safety of recombinant activated factor VII (rFVIIa), prothrombin complex concentrate (PCC), and fibrinogen concentrate (Fib) to reverse apixaban in a rabbit model of bleeding and thrombosis.

Traumatic brain injury (TBI) induces both focal and diffuse lesions that are concurrently responsible for the ensuing morbidity and mortality and for which no established treatment is available. It has been recently reported that an endogenous neuroprotector, the soluble form α of the amyloid precursor protein (sAPPα), exerts neuroprotective effects(More)
Recombinant tissue plasminogen activator (rt-PA) is currently the only approved drug for ischemic stroke treatment, with a dose of 0.9 mg/kg. Since the fibrinolytic activity of rt-PA has been reported in vitro to be 10-fold less potent in rodent than in human, in most in vivo experimental models of cerebral ischemia rt-PA is used at 10 mg/kg. The purpose of(More)
BACKGROUND As a potent anticoagulant agent, rivaroxaban exposes a risk of bleeding. An effective way to reverse its effects is needed. Objectives were to study efficacy and safety of recombinant activated factor VII (rFVIIa) and prothrombin complex concentrate (PCC) to reverse the anticoagulant effect of an overdose of rivaroxaban in a rabbit model of(More)
The aim of this study was to investigate how the brain is affected during systemic inflammation. For this purpose, Swiss mice were challenged with a single intraperitoneal dose of lipopolysaccharide (LPS; 250microg/mouse) to mimic aspects of systemic infection. Spatial learning in Y-maze test demonstrated a differential learning profile during the training(More)
Traumatic brain injury models are widely studied, especially through gene expression, either to further understand implied biological mechanisms or to assess the efficiency of potential therapies. A large number of biological pathways are affected in brain trauma models, whose elucidation might greatly benefit from transcriptomic studies. However the(More)
We previously demonstrated that fenofibrate, a peroxisome proliferator-activated receptor alpha (PPARalpha) agonist, reduced the neurological deficit, the edema and the cerebral lesion induced by traumatic brain injury (TBI). In order to elucidate these beneficial effects, in the present study, we investigated, in the same TBI model, fenofibrate's effects(More)
Progesterone receptors (PR) are expressed throughout the brain. However, their functional significance remains understudied. Here we report a novel role of PR as crucial mediators of neuroprotection using a model of transient middle cerebral artery occlusion and PR knockout mice. Six hours after ischemia, we observed a rapid increase in progesterone and(More)
