Pressure Overload-induced Cardiac Hypertrophy Varies According to Different Ligation Needle Sizes and Body Weights in Mice

Arq. bras. cardiol; 110 (6), 2018
Abstract Background: The cardiac hypertrophy (CH) model for mice has been widely used, thereby providing an effective research foundation for CH exploration. Objective: To research the effects of CH modeling under abdominal aortic constriction (AAC) using different needles and weights in mice. Methods...

Behavior of Blood Pressure Variables in Children and Adolescents with Duchenne Muscular Dystrophy

Arq. bras. cardiol; 110 (6), 2018
Abstract Background: Duchenne muscular dystrophy is an X-chromosome-linked genetic disorder (locus Xp21). Involvement of the cardiovascular system is characterized by fibrous degeneration/replacement of myocytes with consequent ventricular hypertrophy and arterial hypertension. Objective: To assess, by...

Low variation in initial CD4 cell count in a HIV referral center, in Salvador, Brazil, from 2002 to 2015

Braz. j. infect. dis; 22 (3), 2018
ABSTRACT Early initiation of antiretroviral therapy increases the likelihood of effective immune restoration, quality of life, and greater life expectancy for HIV-infected individuals. We evaluated the evolution of mean CD4+ cells count at diagnosis of HIV/AIDS in Salvador, Brazil from 2002 to 2015. We i...

Impact of 1 25(OH) 2 D 3 on TG content in liver of rats with type 2 diabetes

Acta cir. bras; 33 (6), 2018
Abstract Purpose: To evaluate the effects of 1,25 dihydroxy vitamin D3 (1,25(OH)2D3) on the content of triglyceride (TG), as well as on the gene and protein expressions of adiponectin receptor 2 (AdipoR2), p38 mitogen-activated protein kinase (P38MAPK), and lipoprotein lipase (LPL) in the liver of rats...

Antioxidant extract counteracts the effects of aging on cortical spreading depression and oxidative stress in the brain cortex

Acta cir. bras; 33 (6), 2018
Abstract Purpose: To investigate the effects of Murici extract on the brain excitability-dependent phenomenon known as cortical spreading depression (CSD) and on brain oxidative stress. Methods: Adult and aged Wistar rats were supplemented with murici extract (150 mg/kg/day or 300 mg/kg/day) by gavage...

An experimental study on the preventive effects of N-acetyl cysteine and ozone treatment against contrast-induced nephropathy

Acta cir. bras; 33 (6), 2018
Abstract Purpose: To compare the preventive effects of N-acetyl cysteine (NAC), ozone preconditioning and ozone treatment against contrast-induced nephropathy (CIN) in an experimental rat model. Methods: Thirty adult male Wistar rats were randomly distributed into five groups (n=6 for each group). Gro...

Ventajas del uso de estimaciones por intervalos para proporciones poblacionales
Advantages of the use of interval estimations for population proportions

Rev. medica electron; 40 (3), 2018
En este trabajo los autores argumentan la necesidad de incluir el cálculo de estimaciones por intervalos para proporciones poblacionales. Se discute un ejemplo real donde se pone de manifiesto la insuficiencia del intervalo estándar para las proporciones, a pesar de su uso generalizado en las investiga...

The triad of obstructive sleep apnea syndrome, COPD, and obesity: sensitivity of sleep scales and respiratory questionnaires

J. bras. pneumol; 44 (3), 2018
ABSTRACT Objective: To investigate whether the presence of obstructive sleep apnea syndrome (OSAS) alters the perception of respiratory symptoms and quality of life in COPD patients, by using specific questionnaires, as well as to determine whether scales for assessing daytime sleepiness and for screeni...

Validity and reliability of assessing diaphragmatic mobility by area on X-rays of healthy subjects

J. bras. pneumol; 44 (3), 2018
ABSTRACT Objective: To investigate the concurrent validity, as well as the intra- and inter-rater reliability, of assessing diaphragmatic mobility by area (DMarea) on chest X-rays of healthy adults. Methods: We evaluated anthropometric parameters, pulmonary function, and diaphragmatic mobility in 43 pa...
