A strain of the genera Pseudomonas genera was found to possess hemolytic, fibrinolytic and thrombolytic activities. The fibrinolytic activity of the lyophilized unpurified preparation was 900 conventional units/mg. After incubation in the blood plasma, the activity completely remained. The preparation (1 microgram/ml, 750 micrograms of protein) obtained by precipitation with ammonium sulfate (80% saturation) completely lysed in vitro human blood thrombi for 50 min. The strain studied can find practical applications in medical industry.

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.

Fibrinolytic enzymes are promising in treating cardiovascular diseases due to their capacity to dissolve blood clots. The fibrinolytic enzyme from Arthrospira platensis (FEAP) was purified by ion exchange chromatography to investigate its ability to activate plasminogen, as well as its thrombolytic and fibrinogenolytic potential. Subsequently, two different cytotoxic assays (MTT and NR) and hemolysis test were performed to evaluate FEAP's safety.

Background: Whether it is effective and safe to extend the time window of intravenous thrombolysis up to 24 hours after the last known well is unknown. We aimed to determine the efficacy and safety of tenecteplase in Chinese patients with acute ischemic stroke due to large/medium vessel occlusion within an extended time window.
Methods: Patients with ischemic stroke presenting 4.

Background: Acute pulmonary embolism (APE) is a serious cardiovascular condition characterized by high rates of morbidity and mortality, with inflammation playing a significant role in the severity of the disease and patient outcomes. This study aimed to evaluate the effects of thrombolytic therapy on inflammatory markers in patients diagnosed with APE.
Study Design And Methods: The study was conducted retrospectively on 138 individuals, 69 with pulmonary embolism and 69 without pulmonary embolism (control), who were admitted to Necmettin Erbakan University between January 2019 and April 2023.

Beverages formulated from alternative proteins, such as amaranth, are gaining attraction due to changes in human dietary patterns and environmental concerns like resource use and biodiversity loss. This study focuses on assessing the bioactive peptide release from an amaranth protein beverage. This beverage was subjected to a static simulated gastrointestinal digestion (SGD) protocol to evaluate its bioaccessibility and functional potential.
