MARION et al. 8 described the relations between the percentage of maximum heart rate (%HRmax) and the percentage of the maximum oxygen consumption (%VO2max) in cyclic activities, which involve great muscle groups. The Step Training is an acyclic activity in which such relations are not known yet. The aim of the present study was to relate the % HRmax to the % VO2 max in choreographic exercises of Step Training, using a platform of 18 cm in a cadency of 135 bpm of the musical speed. The sample was composed ...

Needle-phobia is usually a great concern in dentistry, and the replacement of painful injections by patient-friendly needle-free topical formulations would bring several advantages in dental practice worldwide. In this pursuit, the effects of combining prilocaine hydrochloride (PCL) and lidocaine hydrochloride (LCL) in different proportions in mucoadhesive films on their in vitro permeation and retention through porcine esophageal mucosa was studied. Complementarily, the permeation and retention of ...

The aim of this work was to develop a mucoadhesive iontophoretic patch for anesthetic delivery in the buccal epithelium. The patch was comprised of three different layers, namely i) drug release (0.64 cm2); ii) mucoadhesive (1.13 cm2); and iii) backing (1.13 cm2). Prilocaine and lidocaine hydrochlorides were used as model drugs (1:1 ratio, 12.5 mg per unit). An anode electrode (0.5 cm2 spiral silver wire) was placed in between the drug release and mucoadhesive/backing layers to enable iontophoresis. ...

Exercise training (ET) is an important tool in the management of patients with chronic venous insufficiency (CVI). The objective of this article was to discuss the effects of ET on the calf pump, functional parameters, and quality of life of patients with mild and advanced CVI. A systematic review was conducted and eleven studies were included. In patients with mild CVI, ET was effective for improving venous reflux, muscle strength, ankle range of motion, and quality of life. In advanced CVI patients, ...

Abstract Background Classic serpiginous choroiditis (SC) usually begins in the peripapillary area and spreads centrifugally, however, in some patients, the lesion can arise in the macular region. An association between lesions resembling classic SC and tuberculosis was recognized as a possibly distinct clinical entity and named as tuberculous serpiginous–like choroiditis. The differentiation of this tuberculous entity from SC is critical because the treatment of the former with immunosuppressive ...

The use of turbochargers is linked to strategies such as engine downsizing or downspeeding, once the use of this device compensates performance losses observed with the reduction of the displaced volume by compressing the air to be admitted. Steady-state tests of turbochargers are common in literature although not consistent with real behavior associated with a vehicular transient operation. To approximate the experimental tests using gas standard test benches to these real conditions, this paper ...

Abstract A simple, isocratic, high‐resolution and prompt HPLC‐PDA method was developed and validated for the simultaneous quantification of prilocaine (PCL) and lidocaine (LCL) hydrochlorides in in vitro buccal iontophoresis‐driven permeation studies. A reversed‐phase C 18 column (250 mm x 4.6 mm, 3μm, 110Å) was used for the chromatographic separation. The mobile phase contained acetonitrile: 0.1M sodium phosphate buffer, pH 7.0 (1:1, v/v), plus 0.05% (v/v) diethylamine. The isocratic flow rate was set ...

A leishmaniose é uma doença tropical negligenciada relacionada com a pobreza. Ela apresenta duas formas clínicas principais: a leishmaniose visceral e a leishmaniose cutânea. O número de casos notificados de leishmaniose visceral diminuiu substancialmente na última década como resultado de um melhor acesso ao diagnóstico e tratamento e de um controle vetorial intenso. Porém permanecem grandes lacunas de evidência, sendo necessários novos instrumentos de identificação e tratamento, antes que a leishmaniose ...

The increase in blood pressure observed during physical activities is exaggerated in patients with hypertension, exposing them to a higher cardiovascular risk. Neural signals from the skeletal muscles appear to be overactive, resulting in this abnormal response in hypertensive patients. In the present study, we tested whether the attenuation of these neural signals in hypertensive patients could normalize their abnormal increase in blood pressure during physical activity. Attenuation of the neural ...

The purpose of the present research was to further evaluate the role of hippocampalN-methyl-d-aspartate (NMDA) receptors in inhibitory avoidance task consolidation. Adult male Wistar rats were trained and tested in a step-down inhibitory avoidance task (0.4 mA footshock, 24 h training–test interval). Immediately after training, animals received a 0.5-μl intrahippocampal infusion of the NMDA receptor antagonist aminophosphonopentanoic acid (AP5) (5.0 μg) or vehicle (phosphate buffer in saline, pH 7.4). ...

Systolic dysfunction is a well-established marker of mortality in patients with Chagas cardiomyopathy (CC). However, its diagnosis is expensive and useful tools for screening these patients are required. The evaluation of the health-related quality of life (HRQoL) detects the patient's perception of the disease's impact. However, its accuracy in identifying patients with CC and systolic dysfunction is unknown. The study aimed to verify the sensitivity, specificity and predictive values of the physical ...
