1. Effects of perilipin-5 on lipid metabolism and high-sensitivity cardiac troponin I
SUMMARY OBJECTIVE: Heart attack is one of the most common causes of sudden death in adults. Therefore, early detection of heart attack and investigation of potential new biomarkers are of great importance. We investigated whether perilipin-5 is a potential biomarker by examining changes in perilipin-5 serum levels along with high-sensitivity cardiac troponi

2. Gênero Cryptostegia: fitoquímica, atividades biológicas e aplicações industriais
The genus Cryptostegia comprises two species, C. madagascariensis (Bojer) and C. grandiflora (Roxb. Ex R. Br) that belong to the Apocynaceae family and are widely distributed in the tropics, as in Australia, New Zealand, India and Brazil, where they cause great socioeconomic and environmental damage, as they are invaders causing damage, mainly in the cultiva

3. Serum Sirtuin 1, 3 and 6 Levels in Acute Myocardial Infarction Patients
Resumo Fundamento: As sirtuínas podem atuar em muitos processos celulares, como a apoptose, reparo de DNA e metabolismo de lipídios e de glicose. Estudos experimentais sugeriram que alguns tipos de sirtuínas possam ter efeitos protetores contra disfunção endotelial, aterosclerose, hipertrofia cardíaca e lesão decorrente de reperfusão. Dados sobre a

4. The Frequency of Infective Endocarditis in Candida Bloodstream Infections: a Retrospective Study in a Child Hospital
Abstract Introduction: Fungal endocarditis is reported less frequently than bacterial endocarditis, with an incidence of 0-12% of the total pediatric infective endocarditis. Objective: In this study, the incidence of infective endocarditis in Candida bloodstream infections in a tertiary hospital during the periods of 2007 and 2016 was reviewed. Methods: P

5. Cardiac protein expression patterns are associated with distinct inborn exercise capacity in non-selectively bred rats
In the present study, we successfully demonstrated for the first time the existence of cardiac proteomic differences between non-selectively bred rats with distinct intrinsic exercise capacities. A proteomic approach based on two-dimensional gel electrophoresis coupled to mass spectrometry was used to study the left ventricle (LV) tissue proteome of rats wit

6. Moderate physical training counterbalances harmful effects of low-protein diet on heart: metabolic, oxidative and morphological parameters
ABSTRACT Aims Maternal low-protein diet induces several impairments on cardiac system. Conversely, moderate exercise has been widely recommended to health improvement due to its effects on heart function. Thus, we investigated whether the moderate physical training is capable to offset the lasting injuries of a maternal protein restriction on the hearts of

7. Myostatin promotes distinct responses on protein metabolism of skeletal and cardiac muscle fibers of rodents
Myostatin is a novel negative regulator of skeletal muscle mass. Myostatin expression is also found in heart in a much less extent, but it can be upregulated in pathological conditions, such as heart failure. Myostatin may be involved in inhibiting protein synthesis and/or increasing protein degradation in skeletal and cardiac muscles. Herein, we used cell c

8. Iron restriction increases myoglobin gene and protein expression in Soleus muscle of rats
ABSTRACT Iron is an important trace element for proper cell functioning. It is present in cytochromes, hemoglobin and myoglobin (Mb), where it binds to oxygen. It is also an electron acceptor in the respiratory chain. Mb is an 18 kDa heme-protein, highly expressed in skeletal muscle and heart. The expression of several genes involved in the metabolism of iro

9. Previous exercise training increases levels of PPAR-α in long-term post-myocardial infarction in rats, which is correlated with better inflammatory response
OBJECTIVE: Exercise is a protective factor for cardiovascular morbidity and mortality, with unclear mechanisms. Changing the myocardial metabolism causes harmful consequences for heart function and exercise contributes to metabolic adjustment modulation. Peroxisome proliferator-activated receptors (PPARs) are also myocardium metabolism regulators capable of

10. Elevated levels of plasma osteoprotegerin are associated with all-cause mortality risk and atherosclerosis in patients with stages 3 to 5 chronic kidney disease
Osteoprotegerin (OPG) regulates bone mass by inhibiting osteoclast differentiation and activation, and plays a role in vascular calcification. We evaluated the relationship between osteoprotegerin levels and inflammatory markers, atherosclerosis, and mortality in patients with stages 3-5 chronic kidney disease. A total of 145 subjects (median age 61 years, 6

11. Classes of secondary metabolites identified in three legume species
The objective of this study was to identify secondary metabolite classes of tropical kudzu, perennial soybean and archer legumes through identification by phytochemical screening and confirmation by infrared (IR), ¹H and carbon-13 NMR spectroscopy of fractions obtained by organic solvents partition of crude extracts. These analyses allowed for proposing the

12. Factors associated with hyperglycemia and low insulin levels in children undergoing cardiac surgery with cardiopulmonary bypass who received a single high dose of methylprednisolone
OBJECTIVES: Administering steroids before cardiopulmonary bypass in pediatric heart surgery modulates systemic inflammatory response syndrome and improves postoperative recovery. However, the use of steroids aggravates hyperglycemia, which is associated with a poor prognosis. Adult patients with systemic inflammatory response syndrome usually evolve with hyp
