Morphometric and aesthetic analysis of people following application of platelet rich plasma for neck rejuvenation

Int. j. morphol; 40 (3), 2022
SUMMARY: Several studies have shown beneficial effects of platelet-rich plasma. However, there are very few studies investigating the effectiveness of PRP in the neck region. We aimed to assess the efficacy of PRP injection for neck rejuvenation in females aged 40-55. Fifty-two female consecutive partici...

Corneal biomechanics and glaucoma beyond the bidirectional impact of intraocular pressure and corneal deformation response

Rev. bras. oftalmol; 81 (), 2022
ABSTRACT The purpose of this study was to highlight the impact of biomechanical corneal response in available in vivo tonometry methods for glaucoma management. Systematic review of non-contact air-puff tonometers that analyzes the corneal deformation response, with special focus on the investigation of ...

Mecánica respiratoria en anestesia general: Revisión de conceptos

Rev. chil. anest; 51 (1), 2022
In anesthesia practice, mechanical ventilation is a fundamental tool, and its correct configuration is essential in the patients care. Airway pressure is often assumed to reflect the forces applied to the lung and is used to monitor mechanical ventilation. This assumption is erroneous because pressure ac...

Efeito da mobilização neural no tratamento da dor em indivíduos com cervicobraquialgia: uma revisão sistemática

: A cervicobraquialgia (CB) é caracterizada por uma dor com origem em diferentes níveis estruturais da coluna cervical baixa (C3- C7), com irradiação bilateral ou unilateral para o membro superior. Considerando as causas e consequências advindas da CB, novas modalidades de tratamento têm sido propo...

Force degradation of elastomeric chains after storage time and mechanical brushing

Braz. dent. j; 32 (4), 2021
Abstract The purpose of this in vitro study was to evaluate the force decrease of different elastomeric chains after different times: initial, 10 minutes, 1 day, 28 days and after mechanical brushing. Twenty orthodontic elastomeric chains segments were utilized for each commercial brand. Initially, the e...

Elastografía en tiempo real (Supersonic), experiencia de un centro en Bogotá

Resumen Introducción: la elastografía en tiempo real, 2D-SWE (Supersonic), es una prueba no invasiva que se utiliza para determinar la elasticidad del hígado y, de esa forma, calcular el grado de fibrosis hepática. En Colombia, la prueba se introdujo en 2016 y no existen hasta el momento estudios de...

Can we expect similar behavior among CuNiTi 35°C wires?

ABSTRACT Objective: This paper aims to verify the thermodynamic, mechanical and chemical properties of CuNiTi 35ºC commercial wires. Methods: Forty pre-contoured copper-nickel-titanium thermodynamic 0.017 x 0.025-in archwires with an Af temperature of 35°C were used. Eight wires from five different ...

Elastografía por ultrasonido endoscópico en el tumor de recto
Endoscopic ultrasound elastography in the rectal tumor

Rev. cuba. med. mil; 49 (3), 2020
Introducción: Para definir una adecuada estrategia terapéutica en el cáncer de recto es preciso una correcta estadificación. El ultrasonido endoscópico es un método de estadiaje preciso que define la profundidad del tumor y el estado nodal. En los tumores tratados con radioterapia disminuye su ren...

Functional magnetic resonance imaging in the evaluation of the elastic properties of ascending aortic aneurysm

Abstract Objective: To evaluate the aortic wall elasticity using the maximal rate of systolic distension (MRSD) and maximal rate of diastolic recoil (MRDR) and their correlation with the aortic size index (ASI). Methods: Forty-eight patients with thoracic aortic aneurysm were enrolled in this study. A ...
