1. Endoscopic Holmium Laser harvesting of bladder mucosal graft for substitution urethroplasty
ABSTRACT Introduction: Tissue transfer has been used in urethral reconstruction for decades, and several grafts have been described (1, 2). The ideal graft would have optimal tissue characteristics and lead to minimal morbidity at the donor site. Urethroplasty using bladder mucosa was first described by Memmelaar in 1947 (3). The main limitation in using bl

2. Sclerotherapy as an esthetic indication in oral vascular malformations: a case series
Abstract Background The use of monoethanolamine oleate 5% is effective for the treatment of vascular malformations with low blood flow. Objectives To report a case series of vascular malformations in the mouth and oral cavity treated with monoethanolamine oleate 5%. Methods A retrospective descriptive study was performed in electronic patient charts cover

3. Mecânica respiratória de pacientes com obesidade mórbida
RESUMO Objetivo avaliar os diferentes componentes da resistência do sistema respiratório e a força muscular respiratória, bem como investigar a ocorrência de limitação de fluxo expiratório (LFE) de pacientes obesos mórbidos (OM) na posição sentada. Métodos a amostra foi composta de OM (IMC ≥ 40 kg/m2) e de indivíduos não obesos (NO) com IMC

5. Escoamento de Calor Representado pela Equação de Laplace e a Transformada de Fourier em Seno e Cosseno
RESUMO Nesse artigo a equação de Laplace foi utilizada para representar uma distribuição de temperaturas estacionárias no primeiro quadrante no plano cartesiano com diferentes condições de fronteira, tendo sido examinada com detalhes, a luz da transformada de Fourier em seno e cosseno. Após obter a solução formal para cada exemplo, foi possível, u

6. Age is the main factor related to expiratory flow limitation during constant load exercise
OBJECTIVE: The objective of this study was to investigate the interaction among the determinants of expiratory flow limitation (EFL), peak oxygen uptake (VO2peak), dysanapsis ratio (DR) and age during cycling at different intensities in young and middle-aged men. METHODS: Twenty-two (11 young and 11 middle-aged) men were assessed. Pulmonary function tests

7. Volatilization of Ammonia Originating from Urea Treated with Oxidized Charcoal
Loss of N through volatilization of ammonia is the main limitation for agricultural use of urea. The aim of this study was to evaluate the volatilization of NH3 from urea granulated (Ug) or urea coated (Ur) with two oxidized charcoals produced by the oxidation of eucalyptus charcoal with 4.0 mol L-1 HNO3, followed by the post-treatment with NaOH (CHox) or wi

8. Control system for continuous positive airway pressure
INTRODUCTION: Continuous Positive Airway Pressure (CPAP) is a mode of non-invasive mechanical ventilation commonly used in neonatology. The incorporation of new therapeutic and technological advances may impact the survival of very low birth weight preterm infants. However, one of the difficulties faced is the high cost of this device and its numerous add-on

9. Analysis of the NTPDase and ecto-5'-nucleotidase profiles in serum-limited Trichomonas vaginalis
Trichomonas vaginalis is a parasite of the human urogenital tract that causes trichomonosis, the most prevalent non-viral sexually transmitted disease. Ectonucleoside triphosphate diphosphohydrolase (NTPDase) family members, which hydrolyse extracellular ATP and ADP and ecto-5′-nucleotidase, which hydrolyses AMP, have been characterised in T. vaginalis. Fo

10. Scaling to generalize a single solution of Richards' equation for soil water redistribution
Using scaling methods, a single solution of Richards' equation (RE) will suffice for numerous specific cases of water flow in unsaturated soils. In this study, a new method is developed to scale RE for the soil water redistribution process. Two similarity conditions are required: similarity in the shape of the soil water content profiles as well as of the wa

11. A negative expiratory pressure test during wakefulness for evaluating the risk of obstructive sleep apnea in patients referred for sleep studies
OBJECTIVE: Obstructive sleep apnea is characterized by increased upper airway collapsibility during sleep. The present study investigated the use of the negative expiratory pressure test as a method to rule out obstructive sleep apnea. METHODS: Flow limitation was evaluated in 155 subjects. All subjects underwent a diurnal negative expiratory pressure test a

12. Relação entre a oferta e a utilização muscular periférica de oxigênio na transição do exercício leve para o intenso em pacientes com insuficiência cardíaca / Peripheral muscle oxygen delivery-to-utilization mismatch in the transition from mild to heavy-intensity exercise in patients with CHF
Impaired muscle blood flow at the onset of heavy-intensity exercise may transiently reduce microvascular O2 pressure and decrease the rate of O2 transfer from capillary to mitochondria in chronic heart failure (CHF). However, advances in the pharmacological treatment of CHF (e.g., angiotensin-converting enzyme inhibitors and third generation of â-blockers)
