    Treatment of rabbits with atherosclerosis induced by cholesterol feeding with daunorubicin associated to a lipid core nanoparticle (LDE)
    (2023) ALBUQUERQUE, Camila Inagaki; TAVARES, Elaine Rufo; GUIDO, Maria Carolina; CARVALHO, Priscila Oliveira; TAVONI, Thauany Martins; LOPES, Natalia Menezes; SILVA, Bruna Miranda de Oliveira; JENSEN, Leonardo; STOLF, Noedir Antonio Groppo; MARANHA, Raul Cavalcante
    Atherosclerosis is a cell-proliferative, chronic inflammatory process. The aim was to investigate whether lipid core nanoparticles (LDE) carrying the anti-cancer agent daunorubicin could have anti-atherosclerotic effects. LDE is taken-up by cellular lipoprotein receptors and is capable of concentrating incorporated drugs in inflammed tissues. New Zealand male rabbits were fed 1% cholesterol diet for 8 weeks. Then, animals were treated with LDE-daunorubicin (6 mg/kg/week, IV, n = 9) or with LDE only (n = 7). Atherosclerotic lesions in LDE-daunorubicin group were 50% smaller than in LDE group. In LDE-daunorubicin, protein expressions of the pro-inflammatory markers CD68, TNF-alpha IL-6 and gene expression MCP-1 were lower than in LDE. Gene expression of IL-1 beta, IL-18 and IL-10 were similar. Protein expressions of VEGF and of pro-apoptotic caspase 3, caspase 9 and BAX, and both protein and gene expressions of VCAM-1 were all lower in LDE-daunorubicin. Gene expression of MMP-12 and protein expression of MMP-2 were lower in LDE-daunorubicin, but MMP-9 was not different. Daunorubicin is known as cardiotoxic, but at echocardiography, LDE-daunorubicin had no differences in arch aorta diameters, systolic and diastolic function and in cardiac hypertrophy compared to LDE group. LDEdaunorubicin was capable of reducing atherosclerotic lesions by different mechanisms without observable toxicities.

    Predictors of Adamkiewicz artery and anterior spinal artery detection through computerized tomographic angiography
    (2017) AMATO, Alexandre Campos Moraes; PARGA FILHO, Jose Rodrigues; STOW, Noedir Antonio Groppo
    Background: The detection of the Adamkiewicz artery and the anterior spinal artery has been associated with the ability to prevent adverse spinal cord outcomes after aortic surgical procedures. Yet, to our knowledge, no previous studies have attempted to use modern predictive models to identify the most important variables in determining artery detectability. Aims: To develop a model to predict the odds of visualizing the Adamkiewicz artery or anterior spinal artery in patients undergoing computerized tomographic angiography. Methods: We conducted a prospective, cross-sectional study. Outcomes of interest were the non-detection of the Adamkiewicz artery and anterior spinal artery, and their corresponding level of origin. Axial images were inspected in high definition in search of two dense spots characterizing the Adamkiewicz artery and anterior spinal artery. A multiplanar three-dimensional reconstruction was then performed using the OsiriX (R) software. Results: A total of 110 participants were part of this analysis. When evaluating risks for the Adamkiewicz artery being undetectable, significant factors could be classified into three broad categories: risk factors for arterial disease, established arterial disease, and obesity. Factors in the former category included metabolic syndrome, hypertension, and smoking status, while factors in the arterial disease included descending aortic aneurysm, mural thrombi, aortic aneurysm without a dissection, and aortic disease in general. In relation to anterior spinal artery not being detectable, significant risk factors included hypertension, smoking status, and metabolic syndrome, while those associated with arterial disease involved aortic disease and arterial thrombi. When evaluating the importance of individual clinical factors, the presence of higher body mass index was the single most important risk factor. Conclusion: Arterial disease, established arterial disease, and increased body mass index are risk factors in the detection of Adamkiewicz artery and anterior spinal artery. Specific diagnostic protocols should be in place for patients with these underlying conditions, thus enhancing the likelihood of detection when the Adamkiewicz artery is indeed present.
