To verify the influence of ozone (O) therapy on an experimental model of rheumatoid arthritis (RA), 30 male Wistar rats were randomly allocated to 2 groups, control (C) and treatment (T), and subdivided into control (C12, C48, C72) and treatment (T12, T48, T72) groups. RA was induced by administration of collagenase plus complete Freud's adjuvant in the knee joint region. The animals were treated with ozone therapy (1 ml O injection in the knee i.

In the present study, light-emitting diodes (LEDs) were used as light source due to their practicality and low cost. The objective was to analyze the effects of transcranial photobiomodulation using 945-nm LED in university students with anxiety and depression.

L-tryptophan is the precursor amino acid of serotonin, which is a neurotransmitter responsible for mood balance and the sense of well-being and can be administered in the form of nanoparticles.
Objective: This study analyzed the effectiveness of L-tryptophan nanoparticles and L-tryptophan on behavioral physiological alterations resulting from AD in animal models.

Capsaicin (CAP) is a secondary metabolite with high therapeutic potential. It displays several bioactive properties including hypolipidemic, antioxidant, anti-inflammatory and analgesic effects. However, CAP presents toxicity to healthy cells and poor pharmacokinetic profile, which is characterized by toxic metabolites and short half-life.

Thirty rats (EG) were irradiated with light-emitting diode (photobiomodulation (PBM)) in the frontal region of the skull after being inoculated with the Aβ toxin in the hippocampus; 30 rats were used as the control group (CG). The analysis was conducted at 7, 14, and 21 days after irradiation.

The synthesis of collagen begins with tissue injury and remains until the end of the healing process. The use of non-coherent light for healing processes is still understudied.

This study investigated the effects of transcranial light emitting diode (LED) on cerebral blood flow in healthy elderly women analyzed by transcranial Doppler ultrasound (TCD) of the right and left middle cerebral artery and basilar artery. Twenty-five noninstitutionalized elderly women (mean age 72 years old), with a cognitive status >24, were assessed using transcranial Doppler ultrasound on two separate occasions: pre-irradiation and post-transcranial LED therapy (TCLT).

Objective: This study evaluated the effects of caffeine and physical exercise on glycemic and insulin responses in diabetic rats.
Objective: To observe the effects of low intensity laser therapy in inflammation, wound healing and epithelialization of island skin grafts.
Methods: Twenty rats were subjected to this grafting technique and divided subsequently into two equal groups, one treated with laser and the other control.
Results: there was less inflammation, faster healing, epithelialization and keratinization in the laser-treated animals when compared to the untreated.
Introduction: Hypertonia is prevalent in anti-gravity muscles, such as the biceps brachii. Neural mobilization is one of the techniques currently used to reduce spasticity.
Objective: The aim of the present study was to assess electromyographic (EMG) activity in spastic biceps brachii muscles before and after neural mobilization of the upper limb contralateral to the hemiplegia.

Introduction: Orofacial pain and pain in the muscles of mastication are frequent symptoms of temporomandibular disorder. The masseter is the closet masticatory muscle to the surface and has the function of raising and retracting the mandible. This muscle has considerable strength and is one of the main muscles involved in the shredding of food It is therefore of utmost importance in the masticatory cycle and generally the most affected by pain and spasms.

Objectives: The proposal of the present study is based on mobilizing the nervous system of the upper hemiplegic limb of stroke victims using the Upper Limb Neurodynamic Test (ULNT 1) and electromyographic analysis of the biceps brachii muscle.
Methods: A pre-experimental study was carried out with pretest and posttest repeated measurements on five stroke victims (4 men and 1 woman; mean age: 52.8 +/- 11 years), with Grade 1 and + 1 spasticity, according to the modified Ashworth scale.
