1. The levels of the blood components of the fibrinolytic enzyme system were measured before, during and after a 4 hr period of exercise in eight subjects.2. Mean plasminogen activator level rose progressively over the first 3 hr with little further change during the 4th hr of exercise. Following the period of exercise there was a rise in a circulating anti-activator which was still present 20 hr after completion of the exercise.3. There was no alteration in the mean blood level of plasminogen, fibrinogen, anti-plasmin or a serum inhibitor of plasminogen activation during or following the exercise.4. The significance of the findings in relation to the mechanism of interaction of the components of the fibrinolytic system is discussed.

Safe Implementation of Treatments in Stroke: a study on intravenous thrombolysis in patients over 80 years of age with acute ischaemic stroke.
BMJ Open
January 2025
Department of Neurology, Karolinska University Hospital, Stockholm, Sweden.
Objectives: To investigate the safety and efficacy outcomes of intravenous thrombolysis (IVT) in patients aged >80 years with acute ischaemic stroke (AIS) after IVT was approved in this patient population in several European and non-European countries during 2018-2019.
Design: This is an observational registry study using prospectively collected data from the Safe Implementation of Treatment in Stroke (SITS) registry. Comparisons will be performed between patients treated post-approval (July 2018 to December 2021) period with those treated pre-approval (June 2015 to June 2018) period using propensity score matching (PSM).
Comparison of the safety and efficacy of dual antiplatelet therapy versus tenecteplase in patients with minor nondisabling acute ischemic stroke.

Center for Rehabilitation Medicine, Department of Neurology, Zhejiang Provincial People's Hospital (Affiliated People's Hospital), Hangzhou Medical College, Hangzhou, Zhejiang, China.
To evaluate the safety and efficacy of dual antiplatelet therapy (DAPT) versus tenecteplase in minor non-disabling acute ischemic stroke. This retrospective observational study utilized data from our stroke database. All consecutive patients with minor non-disabling acute ischemic stroke treated with either DAPT or tenecteplase between January 2020 and June 2023 were included in the analysis.

Background: The benefits of intravenous thrombolysis in patients with acute minor stroke remain controversial. For the aim of providing a better therapeutic strategy, high-quality trials are required to validate the efficacy of thrombolytic medicine other than intravenous recombinant tissue plasminogen and tenecteplase. In the trial, we evaluate the efficacy and safety of urokinase (UK) in acute minor stroke.

Introduction: Pleural infections are a significant cause of mortality. Intrapleural fibrinolytic therapy (IPFT) utilising alteplase and dornase is a treatment option for patients unsuitable for surgery. The optimal dose of alteplase is unknown, and factors affecting treatment success in an Asian population are unclear.
