14. Higher values of triglycerides:HDL-cholesterol ratio hallmark disease severity in children and adolescents with sickle cell anemia
Dyslipidemia has been described in sickle cell anemia (SCA) but its association with increased disease severity is unknown. Here, we examined 55 children and adolescents with SCA as well as 41 healthy controls to test the association between the lipid profiles in peripheral blood and markers of hemolysis, inflammation, endothelial function, and SCA-related c

15. Study of behavior alloy Ti and 316L in to simulated body fluid by electrochemical techniques
ABSTRACT In this work, Ti-316L stainless steel was produced, and its electrochemical behavior was characterized. Ti-steel alloys were produced using an induction furnace, by mixing commercial Ti and 316L stainless steel. X-ray diffraction analyses showed the presence of both the materials, Ti and 316L, in the samples produced. The elemental composition of th

16. Influences on the Functional Behavior of Great Arteries during Orthostasis
Resumo Fundamento: A redução da complacência arterial tem sido associada ao envelhecimento e à hipertensão na postura supina. Entretanto, os efeitos dinâmicos do ortostatismo na distensibilidade aórtica não foram definidos. Objetivo: Determinar a influência ortostática e a interferência da idade, pressão arterial (PA) e frequência cardíaca (F

20. Effect of magnesium sulphate and milrinone on cerebral vasospasm after aneurysmal subarachnoid hemorrhage: a randomized study
Resumo Justificativa: A hemorragia subaracnoidea por aneurisma é uma importante causa de morte prematura e de incapacidade em todo o mundo. O sulfato de magnésio mostra um efeito neuroprotetor e reverte o vasoespasmo cerebral. A milrinona também é usada no tratamento de vasoespasmo cerebral. O objetivo do presente estudo foi comparar o efeito profiláti

21. Transesophageal echocardiography in perioperative period guiding the decision making during hemodynamic instability due to atrial fibrillation
Resumo Justificativa e objetivos: A fibrilação atrial é a arritmia cardíaca mais comum, pode ocorrer durante todo período perioperatório e gerar instabilidade hemodinâmica devido à perda da função sistólica atrial. No manejo da fibrilação atrial, a cardioversão elétrica é uma das opções terapêuticas quando há instabilidade hemodinâmica,

23. Resting spontaneous baroreflex sensitivity and cardiac autonomic control in anabolic androgenic steroid users
OBJECTIVES: Misuse of anabolic androgenic steroids in athletes is a strategy used to enhance strength and skeletal muscle hypertrophy. However, its abuse leads to an imbalance in muscle sympathetic nerve activity, increased vascular resistance, and increased blood pressure. However, the mechanisms underlying these alterations are still unknown. Therefore, w
