Plasminogen activator inhibitor 1 (PAI-1), the primary inhibitor of fibrinolysis and C-reactive protein (CRP), is a predictor of myocardial infarction. Both are upregulated by tumor necrosis factor-alpha (TNF-α) within the obese population. This pilot study tested the hypothesis that TNF-α blockade with pentoxifylline lowers PAI-1 and high-sensitivity CRP (hsCRP) in obese individuals. Twenty participants were treated with pentoxifylline for 8 weeks. A proportional odds model was used to compare the change in PAI-1 and CRP in the pentoxifylline and placebo groups. Plasminogen activator inhibitor 1, but not hsCRP levels, decreased over the 8-week period of the study (P = .025 and P = NS). There was significant dropout of participants due to drug tolerability. These findings suggest that these markers of cardiovascular risk are differentially regulated in obesity and that PAI-1 levels can be reduced by pentoxifylline in this population.

To assess retinal pigment epithelium (RPE) tears in eyes which underwent pars plana vitrectomy (PPV) for submacular hemorrhage (SMH) secondary to age-related macular degeneration and to investigate the prognostic factors of visual outcomes. This study was a retrospective, observational case series that included 24 eyes of 24 patients who underwent PPV with subretinal tissue plasminogen activator and air for SMH. RPE tears were investigated using spectral-domain or swept-source optical coherence tomography images with raster scan, combined confocal scanning laser ophthalmoscope near-infrared images and color fundus photographs.

Background: Primary percutaneous coronary intervention (PPCI) and fibrinolytic or thrombolytic therapy are common treatments for ST-elevation myocardial infarction (STEMI). Primary percutaneous coronary intervention is more effective than thrombolytic therapy, but fibrinolytic therapy is still a preferable option for patients with limited access to healthcare. Alteplase is a tissue plasminogen activator (tPA) used to treat acute myocardial infarction, acute ischemic stroke, and pulmonary embolism.

Background/purpose: Revascularization procedures are used over apexification to treat teeth with necrotic pulp tissues and incomplete root formation. Clinically, inducing proliferation, migration, matrix deposition, and differentiation of stem cells from apical papilla (SCAPs) are critical for pulp regeneration. The study aimed to elucidate the impact of bone morphogenetic protein-4 (BMP-4) on plasminogen activation molecules and the osteogenic/odontogenic differentiation of SCAPs, as well as understand the related signaling mechanisms.

Exploratory laparotomies for blunt or penetrating trauma often result in significant morbidity. Despite advancements in resuscitation, surgical techniques, and antibiotics, intra-abdominal abscesses remain a serious complication, contributing to poor outcomes and extended hospital stays. Percutaneous computed tomography-guided drainage is the standard treatment for abscesses, offering high success rates and low morbidity.

A role for the plasminogen activator (PA) system has been postulated in mammalian gonads, considering the complex process of morphogenesis these organs undergo during their development. Our results show that mouse Sertoli cells under basal conditions produce both types of PA, tissue-type PA (tPA) and urokinase-type PA (uPA), and hormonal treatments increase the production of both enzymes. The increased enzyme secretion does not correlate with a parallel increase in their mRNAs.
