Feasibility of exergaming for upper extremity rehabilitation in people with multiple sclerosis: prospective clinical trial.

BACKGROUND: Exergaming has been suggested as a rehabilitation method since it is more motivational for people with multiple sclerosis (MS, pwMS). However, the major disadvantage of this method is the lack of specific scenarios designed for pwMS. OBJECTIVES: This study aims to assess the feasibility of exergaming, which was developed for pwMS. METHODS: This unblinded prospective clinical trial was performed in the outpatient MS Clinic of Dokuz Eylül University Hospital. Exergaming scenarios were developed in collaboration with medical personnel consisting of physiotherapists and doctors, and computer engineers. A total of 30 participants who had definite MS diagnoses were included. The exergaming scenarios were implemented using the Microsoft Kinect. A physiotherapist applied custom-made exergames for one session. All the participants were assessed immediately after the session. The User Satisfaction Evaluation Questionnaire was used to assess the user's satisfaction with the system and exergaming. RESULTS: The mean age was 41.5, the mean Expanded Disability Status Scale was 4.5 (range between 0 and 7), and the mean disease duration was 10.0 years. Twenty patients were relapsing-remitting, and 10 were secondary-progressive. The mean scores of the User Satisfaction Evaluation Questionnaire were 4.33 (SD = 0.84) for helpfulness for rehabilitation, 1.63 (SD = 1.1) for not disturbing, 4.50 (SD = 1.07) for understandability, 4.0 (SD = 0.91) for easiness to control, and 4.33 (SD = 0.84) for enjoyability. CONCLUSION: These results showed that our custom-made exergaming scenario could be feasible in upper extremity rehabilitation in MS. More research is needed to investigate its effectiveness in the rehabilitation of upper limbs.

Investigation of biological effects of some Mannich Bases containing Bis-1,2,4- Triazole.

In this study, the effects of Mannich bases containing bis-1,2,4-triazole on the levels of in vivo malondialdehyde (MDA) and antioxidant vitamins (A, E, C) were examined in serum, livers and kidneys of rats. DA and vitamin (A, E, C) levels were determined by high performance liquid chromatography (HPLC). Antioxidant effect was investigated by determining the MDA levels in Saccharomyces cerevisiae cells as in vitro. Furthermore, the antitumor effects of compounds were investigated against MCF-7 human breast cancer cells. Interrelations of results among control and compound groups were evaluated using SPSS statistical software package. As a result, some of the compounds showed effective biological activity when compared to control conditions. The test compounds used in this study may be effective for utilization in the selection and design of model compounds for further studies.

Evaluation of the antioxidant effects of melatonin on the larynx mucosa of rats exposed to environmental tobacco smoke.

OBJECTIVES: This study's aim was to investigate the effect of melatonin in terms of mitigating the effects of smoking on the laryngeal mucosa of rats exposed to environmental tobacco smoke. DESIGN: Rats were divided into four groups: Melatonin + Smoking group exposed to smoke with melatonin; Smoking group exposed to smoke without melatonin; Saline group not exposed to smoke without melatonin; Melatonin group not exposed to smoke with melatonin. CuZn-superoxide dismutase (CuZn-SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) activities were evaluated in plasma and tissues. Tissues were also examined the changes of squamous hyperplasia, keratosis, parakeratosis and epithelial hyperplasia by light microscope and the ultrastructural changes by electron microscope. RESULTS: Tissue SOD, CAT and GSH-Px activities were significantly higher in Saline and Melatonin groups than Melatonin + Smoking and Smoking groups. Plasma CuZn-SOD and CAT activities were significantly higher in Saline and Melatonin groups than Smoking group. Plasma GSH-Px showed no significant difference. The rate of epithelial hyperplasia was significantly higher in Smoking group than the other groups. The rate of parakeratosis was significantly higher in Smoking group than the other groups. The epithelial cells in Melatonin + Smoking group displayed, normal cell structure similar to those in Saline group under electron microscope. CONCLUSIONS: The study shows that smoking induces substantial pathological changes in the laryngeal mucosa and melatonin may have some beneficial effects in partially reversing smoking-induced laryngeal injury by inducing the expression of antioxidants; biochemical and histological outcomes also support these findings due to preventing tissue damage in laryngeal mucosa exposed to smoke.
