Evaluation of the Effects of Radiation Therapy on Muscle Contractibility and Skin Healing: An Experimental Study of the Cancer Treatment Implications.

Background: Radiotherapy can affect healthy cells, resulting in side effects. This study aimed to assess the impact of radiotherapy on soft tissue in surgical wounds in rats.

Methods: The animals were divided into four groups: control (S) group without irradiation, immediate irradiation (S-IIr) group receiving irradiation right after surgery, late irradiation (S-LIr) group receiving irradiation four weeks after surgery, and early irradiation (Ir-S) group receiving irradiation before surgery.

Antifungal and anti-biofilm effect of the calcium channel blocker verapamil on non-albicans Candida species.

Candida is a human fungal pathogen that causes a wide range of diseases. Candida albicans is the main etiologic agent in these diseases; however, infections can be caused by non-albicans Candida species. Virulence factors such as biofilm production, which protect the fungus from host immunity and anti-fungal drugs, are important for the infection.

Effects of Neuromuscular Electrical Stimulation on the Masticatory Muscles and Physiologic Sleep Variables in Adults with Cerebral Palsy: A Novel Therapeutic Approach.

Cerebral palsy (CP) is a term employed to define a group of non-progressive neuromotor disorders caused by damage to the immature or developing brain, with consequent limitations regarding movement and posture. CP may impair orapharygeal muscle tone, leading to a compromised chewing function and to sleep disorders (such as obstructive sleep apnea). Thirteen adults with CP underwent bilateral masseter and temporalis neuromuscular electrical stimulation (NMES) therapy.

Test-retest reliability of electromyographic variables of masseter and temporal muscles in patients with cerebral palsy.

Introduction: The aim of this study was to evaluate the reliability of surface electromyography of the masticatory muscles in patients with cerebral palsy.

Methods: Surface electromyography was performed over the masseter and temporal muscles in 15 patients with cerebral palsy with the mandible at rest and during maximum clenching effort in two sessions. The data were analyzed using the root mean square amplitude, mean frequency, median frequency, zero crossings and approximate entropy.
