1. EXERCISE RESISTANCE EFFECT ON ADVERSE REACTION RATE IN HEART FAILURE
RESUMO Introdução: A insuficiência cardíaca é uma doença comum em idosos. No estágio final, além da disfunção cardíaca, os pacientes geralmente acompanham uma redução no teor de gordura e da massa magra. Objetivo: Estudar os efeitos da resistência ao exercício e da taxa de reação adversa em pacientes com insuficiência cardíaca. Métodos

2. Doppler Ultrasound Testing Suggests Hemorrhoids in Females may be a Consequence of Impaired Blood Flow Associated with Pelvic Organ Prolapse
Abstract Background It has been observed that there is a high incidence of hemorrhoids in female patients with pelvic organ prolapse. Also, in these patients, hemorrhoidal disease improves after the surgical correction of the pelvic organ prolapse. Objective Our hypothesis was that a cause-effect relationship between pelvic organ prolapse, and hemorrhoids

3. Presentation delay, misdiagnosis, inter-hospital transfer times and surgical outcomes in testicular torsion: analysis of statewide case series from central Brazil
ABSTRACT Purpose To estimate statewide presentation delay, misdiagnosis rate, inter-hospital transfer times and testicular salvage for testicular torsion patients treated in our state’s public health system. Patients and Methods Case series of consecutive testicular torsion patients treated in our state’s public health system between 2012-2018. Predi

4. Effect of hCG application at different moments of the estrous cycle on corpus luteum and uterine vascularization and serum progesterone concentration in mares
Abstract Establishment of pregnancy after embryo transfer is the ultimate goal of an embryo transfer program and increasing pregnancy rates and reducing pregnancy loss are mandatory. The utilization of treatments to improve conception rates in recipient mares has been the focus of several research groups over the last years and the results are controversial.

5. Effect of eCG on the follicular dynamics and vascularization of crossbred cows with different circulating progesterone concentrations during synchronization of ovulation in an FTAI protocol
RESUMO: Objetivou-se neste estudo avaliar o efeito do tratamento com gonadotrofina coriônica equina (eCG) sobre a dinâmica e função folicular em fêmeas mestiças com diferentes concentrações circulantes de P4 durante a sincronização da ovulação em um protocolo de IATF. Para tanto, foram utilizadas 30 fêmeas mestiças e submetidas a um protocolo d

6. O Princípio de Equivalência
Resumo Revisamos a base conceitual sobre o Princípio de Equivalência, elucidando seu papel crucial na formulação das teorias gravitacionais. Analisamos as consequências diretas do princípio, reinterpretando de modo relativisticamente coerente a forma como deve ser considerado na dedução do redshift gravitacional via utilização do efeito Doppler rel

7. Effect of cilostazol in experimental model of degloving injuries in rat limbs
Abstract Purpose: To evaluate the effect of the cilostazol on the evolution of partially avulsed flaps, using experimental model of cutaneous degloving in rat limbs. Methods: A controlled and randomized experimental study was carried out in which the blood flow and the percentage of flap necrosis were evaluated. We compared the study group, which received

8. Efecto Doppler con una fuente que acelera: una simple aproximación gráfica
The classical Doppler effect produced by an accelerated source is considered by using a naive kinematical, graphical approach. We obtain expressions for the frecuency detected by a stationary observer from a source that moves towards or away from him. An extension to the relativistic case is also analysed.

9. Positron Annihilation Spectroscopy Study on Annealing Effect of CuO Nanoparticles
The microstructure and defects of CuO nanoparticles under isochronal annealing were investigated by positron annihilation spectroscopy (PAS), X-ray diffraction (XRD) and scanning electron microscope (SEM). XRD and SEM results indicated that the average grain sizes of CuO nanoparticles grew slowly below 800 °C, and then increased rapidly with the annealing t

10. Blood flow velocity in monocular retinoblastoma assessed by color doppler
OBJECTIVE: To analyze the flow of retrobulbar vessels in retinoblastoma by color Doppler imaging. METHODS: A prospective study of monocular retinoblastoma treated by enucleation between 2010 and 2014. The examination comprised fundoscopy, magnetic resonance imaging, ultrasonography and color Doppler imaging. The peak blood velocities in the central retinal

11. Effect of alpha-7 nicotinic acetylcholine receptor activation on beta-amyloid induced recognition memory impairment. Possible role of neurovascular function
PURPOSE: To evaluate the effects of PHA-543613 (α7-nAChR agonist) and galantamine (acetylcholinesterase inhibitor (AChEI)) on recognition memory and neurovascular coupling (NVC) response in beta-amyloid (Aβ) 25-35-treated mice. METHODS: PHA-543613 (1 mg/kg, i.p.), and galantamine (3 mg/kg, s.c.), effects were tested in Aβ25-35 mice model of AD. α7-nA
