1. Hypotension and Bradycardia Produced by Transthoracic Application of Low-Intensity Ultrasound Therapy in Hearts of Healthy Rats - A Preclinical Study
Abstract Objective: To investigate the cardiovascular effects produced by transthoracic application of low-intensity pulsed ultrasound therapy (LIPUST). Methods: Three-month-old male Wistar rats (± 300 g, N=16) were randomly allocated in two groups, namely SHAM (control group, faked procedures) and UST (animals treated with LIPUST). These animals, under a

2. Comparison of the effects of low-level laser and pulsed and continuous ultrasound on pain and physical disability in chronic nonspecific low back pain: a randomized controlled clinical trial
Abstract Objective: To compare the short-term effects of pulsed laser and pulsed and continuous ultrasound on pain and functional disability in women with chronic non-specific low back pain. Methods: The sample was composed of 100 volunteers randomly allocated into four groups: The Pulsed Laser Group (n = 26) was treated with 3 J/cm2; the Pulsed Ultrasound

3. Low-intensity pulsed ultrasound promotes tissue regeneration in rat dental follicle cells in a porous ceramic scaffold
Abstract The aim of this study was to investigate the effects of low-intensity pulsed ultrasound (LIPUS) on the osteogenic differentiation of dental follicle cells (DFCs) in vitro and on the regenerative effects of DFC-OsteoBoneTM complexes in vivo. DFCs were isolated and characterized. In the in vitro study, DFCs were cultured in an osteogenic medium in the

4. Low-intensity pulsed ultrasound promotes proliferation and migration of HaCaT keratinocytes through the PI3K/AKT and JNK pathways
Although the effects of low-intensity pulsed ultrasound (LIPUS) on diverse cell types have been fully studied, the functional role of LIPUS in keratinocytes remains poorly understood. This study aimed to investigate the effects of LIPUS on proliferation and migration of HaCaT cells as well as the regulatory mechanisms associated with signaling pathways. Huma

5. Low intensity ultrasound therapy induces angiogenesis and persistent inflammation in the chronic phase of the healing process of third degree burn wounds experimentally induced in diabetic and non-diabetic rats
ABSTRACT PURPOSE: To evaluate the effects of low intensity ultrasound on the healing process of third degree burn wounds in experimentally induced diabetic Wistar rats. METHODS: One hundred rats were divided into: control group; non-diabetic treated group; diabetic control group; diabetic treated group. The therapy was performed with a 3MHz ultrasound appl

6. Effects of low-intensity pulsed ultrasound on injured skeletal muscle
BACKGROUND: Low-intensity pulsed ultrasound (LIPUS) has been shown to stimulate tissue metabolism and accelerate muscle healing. However, the optimal parameters in the use of LIPUS are still not clear. OBJECTIVE: The aim of this study was to analyze the effects of LIPUS on muscle healing in rats subjected to a cryolesion. METHOD: Twenty rats were d

7. Avaliação do reparo tecidual em defeito ósseo por microtomografia tridimensional por raio X / Evaluation of tissue repair after bone fracture using 3D X-ray microtomography
Fracture is a bone discontinuity that can be surgically produced or caused by an impact that exceeds the mechanical strength of bone by initiating a series of systemic events and specific tissue response. Radiological tests are commonly performed in clinical and animal experiments for monitoring the bone healing by providing information about the alignment o

8. Efeitos do laser terapêutico e do ultrassom pulsado de baixa intensidade na expressão de genes relacionados à diferenciação celular durante o processo de reparo ósseo
Fractures of delayed consolidation and fractures with non-union are commonly found in medical practice and are associated with high morbidity and mortality. Within this context, biochemical and biophysical resource have been studied in an attempt enhance bone healing. Among these may be highlighted the use of low level laser therapy (LLLT) and low intensity

9. Efeitos do ultra-som pulsado de baixa intensidade sobre a musculatura lisa e sobre o epitélio endometrial em úteros de ratas adultas, após uterotomia: estudo experimental / Effects of the pulsed ultrasound of low intensity on the flat musculature and on the epithelium endometrial in uteruses of adult female rats, after uterotomia: experimental study
Esta investigação experimental teve como finalidade de avaliar os efeitos do ultra-som pulsado de baixa intensidade sobre a regeneração do miométrio e do endométrio de ratas submetidas à uterotomia. Foram utilizadas neste experimento 20 ratas adultas da raça Wistar, submetidas a uma uterotomia mediante incisão longitudinal de 1,5 cm total de uma das

10. Development of ultrasonic waveguide for monitoring dental implant osseointegration / Desenvolvimento de guia de ondas ultra-sônicas para monitorar a osseointegração de implantes dentários
Available equipments for clinical assessment of dental implants monitor changes in stiffness but are not able to quantify the osseointegration level. Literature shows that the application of low-intensity pulsed ultrasound stimulates the healing of bone fractures and the bone ingrowth into implants pores, indicating that an ultrasonic waveguide could be used

11. Effect low-intensity pulsed ultrasound in peripheral nerve regeneration of the rats / Ultra-som pulsado de baixa intensidade na regeneração nervosa periférica de ratos
O ultra-som é uma das formas de tratamento terapêutico, não-invasivo, que pode auxiliar na regeneração nervosa periférica. Dentre todas estas técnicas não-invasivas de regeneração nervosa periférica, pouco se sabe sobre a influência do ultra-som na regeneração desse tecido. Para tanto foi realizado um trabalho experimental com o objetivo de ava

12. Utilização do exercício físico versus ultra-som pulsado de baixa intensidade na manutenção de massa óssea / Study of low-intensity pulsed ultrasound and of the physical exercise effect post-ovariectomy bone mass maintenance in an animal model
O ultra-som pulsado de baixa intensidade é uma onda mecânica com efeitos osteogênicos promisso- res para o tratamento da osteoporose. Baseada neste efeito, a pesquisa tem como objetivo a identificação das mudanças causadas pela aplicação do ultra-som em ossos osteopênicos e a comparação com as mudanças causadas pelos exercícios físicos. Aplicou
