Abstract: Determining acute ischemic stroke (AIS) etiology is crucial for guidance of secondary prevention. Here, the inventors performed a correlation analysis between AIS etiology and AIS thrombus cellular composition and content, as assessed using quantitative biochemical assays. In particular, homogenates of 250 AIS patient thrombi were prepared by mechanical grinding. Platelet, red blood cell, and leukocyte content of AIS thrombi were estimated by quantification of glycoprotein (GP)VI, heme, and DNA in thrombus homogenates. AIS etiology was defined as cardioembolic, non-cardioembolic, or embolic stroke of undetermined source (ESUS), according to the TOAST classification. Cardioembolic thrombi were richer in DNA (35.8 vs 13.8 ng/mg, p<0.001) and poorer in GPVI (0.104 vs 0.117 ng/mg, p=0.045) than non- cardioembolic ones. The area under the receiver operating characteristic curve of DNA content to discriminate cardioembolic thrombi from non-cardioembolic was 0.72 (95% Cl, 0.63 to 0.81). With a threshold of 44.

Abstract: An easily administrable drug treatment to increase the recanalization rate associated with intravenously t-PA would represent a major advance in the acute ischemic stroke (AIS) management. The inventors demonstrate the presence of NETs network in intracranial thrombus extracted during AIS reperfusion procedures. Thrombi are encapsulated by these NETs network, which confer t-PA resistance. In fact, in presence of DNAse 1, t-PA-induced thrombolysisis accelerated, whereas DNAse alone is inefficient. These results suggest that a co-therapy associating t-PA and DNAse 1 may potentialize t-PA efficacy. Accordingly, the present invention relates to a method of treating an acute ischemic stroke (AIS) in a patient in need thereof comprising administering to the patient a therapeutically effective combination of t-PA and DNAse, wherein administration of the combination results in enhanced therapeutic efficacy relative to the administration of t-PA alone.

Abstract: This enclosure comprises a body which itself comprises: a structure which internally delimits a processing space which opens at the outer side of the structure by way of an opening, at least one framework element which is fixed in a removable manner to the structure in order to delimit, in the opening (13), at least two zones for access to separate regions of the processing space. At least two gates are mounted so as to be movable on the structure in order selectively to close and open the access zones. Application, for example, to CO2 incubators.
