Comparison of the diagnostic performance of non-contrast MR angiography and planar V/Q scintigraphy for pulmonary embolism: a systematic review and meta-analysis.
Eur Radiol
January 2025
Pontifícia Universidade Católica do Rio Grande do Sul, Porto Alegre, Brazil.
Objectives: To conduct a meta-analysis of the diagnostic performance of non-contrast magnetic resonance pulmonary angiography (NC-MRPA) and ventilation-perfusion (V/Q) scintigraphy for the detection of acute pulmonary embolism (PE).
Materials And Methods: Systematic searches of electronic databases were conducted from 2000 to 2024. Primary outcomes were per-patient sensitivity and specificity of NC-MRPA and V/Q scintigraphy.
Effect of rapid and slow intravenous injection of sodium penicillin on arterial blood pressure in isoflurane-anesthetized horses during surgery.

Department of Clinical Studies, Ontario Veterinary College, University of Guelph, Guelph, ON, Canada.
Objective: To determine the effects of rapid (1 minute) and slow (10 minutes) intravenous (IV) injection of sodium penicillin on arterial blood pressure in anesthetized horses.
Study Design: Prospective randomized clinical trial.
Animals: A group of 29 client-owned horses of various breeds, 1-20 years old, with body masses of 360-710 kg.
Thrombolytic efficacy and safety of recombinant scu-PA in a rabbit retinal vein occlusion model.

Retinal vein occlusion (RVO) has become the second most common retinal vascular disease after diabetic retinopathy. Existing therapeutic approaches, including intravitreal injection of antivascular endothelial growth factors (anti-VEGFs) and/or glucocorticoids and laser therapy, primarily address secondary macular edema and neovascularisation. However, these strategies do not address the underlying cause of the disease and may have harmful side effects.

The main treatments in the acute phase include intravenous thrombolysis, endovascular stent-assisted vascular thrombectomy and antiplatelet therapy. Due to the limitations of the time window and the risk of early intracranial hemorrhage, finding active treatment plans is crucial for improving therapy.

Laboratory of Functional Molecular Chemistry, Kobe Pharmaceutical University, 4-19-1, Motoyamakita-machi, Higashinada-ku, Kobe 658-8558, Japan.
Protein aggregation, a major concern in biopharmaceutical quality control, can be accelerated by various stresses during clinical handling. This study investigated potential aggregation risk factors during dilution process with syringe handling for intravenous administration. Using γ-globulin and IgG solutions as surrogate models of antibody therapeutics, we examined the effects of high sliding speeds and piston operations of the syringe on protein aggregation during saline dilution.
