1. Comparison between the Effects of Bretschneider’s HTK Solution and Cold Blood Cardioplegia on Systemic Endothelial Functions in Patients who Undergo Coronary Artery Bypass Surgery: a Prospective Randomized and Controlled Trial
Abstract Objective: To investigate the effects of Bretschneider’s histidine-tryptophan-ketoglutarate (HTK) solution and cold blood cardioplegia on systemic endothelial functions. Methods: A total of 50 patients who underwent isolated coronary artery bypass surgery between March 2018 and May 2018 were randomly divided into two groups - group 1 (Bretschn

2. Histopathology and immunohistochemistry of peripheral neural sheath tumor and perivascular wall tumor in dog
RESUMO Sarcoma de tecidos moles (STM) compreende um grupo heterogêneo de neoplasias malignas, derivadas de tecidos extraesqueléticos, que podem apresentar alterações histopatológicas similares. Os padrões histopatológicos sugestivos de tumor de parede perivascular (TPP) e de tumor de bainha de nervo periférico (TBNP) têm sido descritos. Este estudo

3. Ulinastatin attenuates vascular endothelial cell damage in pregnant women with severe pre-eclampsia
Abstract: The use of ulinastatin for pancreatitis and sepsis have been described. This study was designed to evaluate the effect of ulinastatin on vascular endothelial cell damage and coagulation in pregnant women with severe pre-eclampsia (PE).From October 2015 to November 2017 at Tianjin Central Hospital of gynecology and obstetrics in China. Eighty pregna

4. Impact of Arterial Procedures on Coagulation and Fibrinolysis - A Pilot Study
Abstract Objective: The main goal of our study was to assess the impact of vascular procedures on the activity of hemostatic and fibrinolytic pathways. Methods: We enrolled 38 patients with ≥ 45 years old undergoing surgery for abdominal aortic aneurysm or peripheral artery disease under general or regional anesthesia and who were hospitalized at least o

5. Plasmatic ADAMTS-13 metalloprotease and von Willebrand factor in children with cyanotic congenital heart disease
Changes in plasma von Willebrand factor concentration (VWF:Ag) and ADAMTS-13 activity (the metalloprotease that cleaves VWF physiologically) have been reported in several cardiovascular disorders with prognostic implications. We therefore determined the level of these proteins in the plasma of children with cyanotic congenital heart disease (CCHD) undergoing

6. Decreased plasma ADAMTS-13 activity as a predictor of postoperative bleeding in cyanotic congenital heart disease
OBJECTIVE: To analyze the preoperative plasma antigenic concentration and activity of von Willebrand factor and its main cleaving protease ADAMTS-13 in pediatric patients with cyanotic congenital heart disease undergoing surgical treatment and investigate possible correlations with postoperative bleeding. METHODS: Plasma antigenic concentrations (von Will

7. Inflammation in disseminated lesions: an analysis of CD4+, CD20+, CD68+, CD31+ and vW+ cells in non-ulcerated lesions of disseminated leishmaniasis
Disseminated leishmaniasis (DL) differs from other clinical forms of the disease due to the presence of many non-ulcerated lesions (papules and nodules) in non-contiguous areas of the body. We describe the histopathology of DL non-ulcerated lesions and the presence of CD4-, CD20-, CD68-, CD31- and von Willebrand factor (vW)-positive cells in the inflamed are

8. The infection of microvascular endothelial cells with ExoU-producing Pseudomonas aeruginosa triggers the release of von Willebrand factor and platelet adhesion
An increased plasma concentration of von Willebrand factor (vWF) is detected in individuals with many infectious diseases and is accepted as a marker of endothelium activation and prothrombotic condition. To determine whether ExoU, a Pseudomonas aeruginosa cytotoxin with proinflammatory activity, enhances the release of vWF, microvascular endothelial cells w

9. Avaliação da ADAMTS13 e de marcadores inflamatóriosem pacientes com Tromboembolismo venoso / Evaluation of ADAMTS13 and inflammatory markers in patients with venous thromboembolism
Níveis elevados de marcadores inflamatórios e fatores de coagulação têm sido relacionados com a patogênese do TEV. Particularmente, a relação inversa entre o FVW e a atividade da ADAMTS13 já foi previamente descrita em pacientes com trombose arterial. Níveis de FVW também mostraram-se elevados durante processos inflamatórios e portanto, poderiam

10. Estudo de marcadores de disfunção endotelial e de inflamação em portadores de hipertensão arterial pulmonar: implicações terapêuticas e prognósticas / Markers of endothelial dysfunction and inflammatory mediators in pulmonary arterial hypertension: therapeutic and prognostic implications
A disfunção microvascular, envolvendo células endoteliais, plaquetas e leucócitos, está presente na hipertensão arterial pulmonar (HAP), associando-se a risco aumentado de trombose e menor sobrevida. Estudos sobre disfunção microvascular são escassos em outras formas da doença que não a idiopática. Os objetivos do estudo foram: caracterizar a dis

11. Plasma von Willebrand factor as a predictor of survival in pulmonary arterial hypertension associated with congenital heart disease
Biomarkers have been identified for pulmonary arterial hypertension, but are less well defined for specific etiologies such as congenital heart disease-associated pulmonary arterial hypertension (CHDPAH). We measured plasma levels of eight microvascular dysfunction markers in CHDPAH, and tested for associations with survival. A cohort of 46 inoperable CHDPAH

12. Influência dos parâmetros da coagulação no sangramento após ligadura elástica de varizes esofagianas em pacientes cirróticos / Influence of coagulation parameters in the blood after band ligation of esophageal varices in cirrhotic patients
BACKGROUND &AIMS. There is controversy over whether coagulation status predicts bleeding caused by ulceration after esophageal varices band ligation (EVL). METHODS: EVL was performed for primary (n=45) or secondary (n=105) prophylaxis in 150 patients with cirrhosis (Child A, n=74 [49%]; Child B, n=42 [28%]; Child C, n=34 [23%]). International Normalized Rati
