1. The Concept of a Rupture Risk Envelope for the Cochleo-Saccular Membranes
Abstract Introduction Alterations in endolymphatic pressure have long been suspected of being associated with the development of endolymphatic hydrops and rupture of the membranous labyrinth. More recently, there has been a focus on how membrane mechanics might contribute to membrane rupture. This is suspected to involve the viscoelastoplastic properties of

2. Mecânica Atrial na Cardiomiopatia Hipertrófica: Discriminando Hipertrofia de Fibrose Ventricular
Resumo Fundamento A cardiomiopatia hipertrófica (CMH) e a hipertrofia ventricular esquerda (HVE) secundária à hipertensão arterial sistêmica (HAS) podem estar associadas a anormalidades funcionais do átrio esquerdo (AE). Objetivos Caracterizar a mecânica do AE na CMH e na HAS e avaliar qualquer correlação com a extensão da fibrose ventricular e

3. Strain Magnitude Assessed at Rest and During Stress Echocardiography in Patients with Normal Coronary Flow Reserve
Abstract Background Coronary flow and myocardial contractile performance assessed by strain magnitude increase during a dobutamine stress echocardiogram (DSE). Normal coronary flow reserve (CFR) can be attained upon completion of a DSE at age-predicted maximum heart rate (HR) (HRmax = 220 - age)] or submaximal HR [(0.85) HRmax] or before completion (early

4. Chronic Obstructive Pulmonary Disease: The Role of Myocardial Deformation Indices and Right Ventricle Three-Dimensional Echocardiography
Abstract Background: Right ventricular dysfunction is a major complication in chronic obstructive pulmonary disease (COPD) and, despite its prognostic implications, is rarely considered in routine clinical analysis. Objectives: To compare RV function variables with standard and advanced echocardiographic techniques in patients with stable COPD and controls

5. Kinetic study and thermodynamic equilibrium modeling of the Co(II) and Mn(II) bioadsorption using the Rhodococcus opacus strain
Abstract Microbial biomass is considered a renewable and environmentally friendly resource. Thus, the research conducted a kinetic study and thermodynamic equilibrium modeling of the cobalt (Co) and manganese (Mn) bioadsorption process using the Rhodococcus opacus (RO) strain as a biosorbent. The inactive biomass subjected to 0.1 M NaOH pretreatment was brou

6. Art and science: impact of semioccluded vocal tract exercises and choral singing on quality of life in subjects with congenital GH deficiency
ABSTRACT Objectives: Currently, not much is known about the interactions between voice and growth hormone (GH). We have described large kindred with isolated GH deficiency (IGHD) due to a GHRH receptor mutation, resulting in severe short stature and high-pitched voice. These IGHD individuals have little interest in GH treatment, as they consider themselves

7. Role of elastography strain ratio and TIRADS score in predicting malignant thyroid nodule
ABSTRACT Objectives: To evaluate the performance of telemonitoring in detecting clinical and psychological needs and adherence to the protective measures imposed by the COVID-19 pandemic in addition to providing remote assistance for patients with type 1 diabetes (T1D) in a public university center in Brazil. Subjects and methods: Telemonitoring protocol i

8. Editorial Comment: Does the Use of a Robot Decrease the Complication Rate Adherent to Radical Cystectomy? A Systematic Review and Meta-Analysis of Studies Comparing Open with Robotic Counterparts
ABSTRACT This letter to the Editor aims to provide suggestions and recommendations for the management of urological conditions in times of COVID-19 crisis in Brazil and other low- and middle-income countries. It is important to highlight that one of the main characteristics of this pandemic is the oversaturation of the health system capacity, mostly due to a

9. Rhizobium rhizogenes-mediated transformation of Rhodiola rosea leaf explants
ABSTRACT Rhodiola rosea L. is an endangered medicinal plant distributed in mountains and in high latitude regions. For its conservation, sustainable methods for the obtaining of its bioactive compounds must be developed. This work hypothesized that leaf, stem and rhizome explants of R. rosea from different geographical origins respond differently to inoculat

10. Avaliação da deformação miocárdica pela ecocardiografia feature tracking em gatos com defeito perimembranoso do septo ventricular
RESUMO O desenvolvimento de novas ferramentas, como a ecocardiografia bidimensional feature tracking (2D-FTI), permite diagnosticar, de forma precoce, se há disfunção miocárdica em doenças cardíacas, inclusive as congênitas. O defeito septal ventricular (DSV) é a alteração congênita mais observada em felinos, no entanto pouco se sabe sobre a disfu
