Safety and Efficacy of MLC601 in Iranian Patients after Stroke: A Double-Blind, Placebo-Controlled Clinical Trial

Objective. To investigate the safety and efficacy of MLC601 (NeuroAid) as a traditional Chinese medicine on motor recovery after ischemic stroke. Methods. This study was a double-blind, placebo-controlled clinical trial on 150 patients with a recent (less than 3 month) ischemic stroke. All patients were given either MLC601 (100 patients) or placebo (50 patients), 4 capsules 3 times a day, as an add-on to standard stroke treatment for 3 months. Results. Sex, age, elapsed time from stroke onset, and risk factors in the treatment group were not significantly different from placebo group at baseline (P > .05). Repeated measures analysis showed that Fugl-Meyer assessment was significantly higher in the treatment group during 12 weeks after stroke (P < .001). Good tolerability to treatment was shown, and adverse events were mild and transient. Conclusion. MLC601 showed better motor recovery than placebo and was safe on top of standard ischemic stroke medications especially in the severe and moderate cases

CGMP: cloud-assisted green multimedia processing

With continued advancements of mobile computing and communications, emerging novel multimedia services and applications have attracted lots of attention and been developed for mobile users, such as mobile social network, mobile cloud medical treatment, mobile cloud game. However, because of limited resources on mobile terminals, it is of great challenge to improve the energy efficiency of multimedia services. In this paper, we propose a cloud-assisted green multimedia processing architecture (CGMP) based on mobile cloud computing. Specifically, the tasks of multimedia processing with energy-extensive consumption can be offloaded to the cloud, and the face recognition algorithm with improved principal component analysis and nearest neighbor classifier is realized on CGMP based cloud platform. Experimental results show that the proposed scheme can effectively save the energy consumption of the equipment

Energy-Efficient Service-Oriented Architecture for Mobile Cloud Handover

Mobile cloud computing uses features to deliver outsourcing data to remotely available mobile devices. However, the flexible nature of the mobile device is a critical challenge for the mobile cloud computing environment. The mobile phone significantly degrades the data transfer performance when initiating the handover process. Thus, an energy-efficient handover process could improve the quality of service (QoS). Here, we introduce a secure energy-efficient and quality-of-service architecture (EEQoSA) for the handover process in the mobile cloud computing environment. The proposed architecture involves four layers: application, the Internet protocol multimedia subsystem (IPMS), communication, and media with connectivity layers. These four layers collectively handle the energy-efficiency, security and QoS parameters. Existing service-oriented architectures designed for mobile cloud computing are based on the symmetric encryption cryptography to support different media services. However, this approach easily allows an adversary to expose the symmetric key and gain access to private data. Thus, our proposed architecture uses the secure and strong authentication (SSA) process at the IPMS layer by protecting the media services from unauthorized users, as the IPMS is the central layer that could be the entry point for an adversary. Furthermore, to extend the mobile lifetime during the handover process, an energy detection (ED) model is deployed at the communication layer to detect the energy level of the mobile device prior to the handover initialization process. The media with the connectivity layer supports the secure handover process using a priority enforcement module that allows only legitimate users to complete the re-registration process after initiating the handover. Finally, the architecture is tested using the CloudSim simulation environment and validated by a comparison with other known service-oriented architectures.https://doi.org/10.1186/s13677-017-0079-

The effect of early intervention of mirror visual feedback on pain, disability and motor function following hand reconstructive surgery: a randomized clinical trial

Objective: To determine the effect of mirror visual feedback (MVF) on disability, pain, and motor function on patients who underwent hand reconstructive surgery. Design: Randomized, single-blinded controlled trial. Setting: Rehabilitation center. Subjects: A total of 40 patients who were randomly assigned into the intervention group (n = 20) and control group (n = 20) participated in this study. Interventions: The rehabilitation sessions took place twice a week for eight weeks. The control group received traditional rehabilitation for 75 minutes. While the intervention group performed MVF and traditional rehabilitation for 30 and 45 minutes, respectively. Measures: Pain and disability of the hand were assessed with McGill pain questionnaire and Disability of Arm, Shoulder, and Hand (DASH) scores. The range of joint motion was evaluated by Goniometer, and the strength of grip and pinch was evaluated by Dynamometer and Pinch gauge and dexterity evaluated by Minnesota Manual Muscle test. Results: The results indicated that both traditional and MVF methods induced significant decreasing pain (Pain Rate Index: F = 68.48, P = 0.000; Number of Word Count: F = 70.96, P = 0.000), disability (F = 50.08, P = 0.000) and increasing dexterity (placing test: F = 28.73, P = 0.000), and range of motion (F = 33.16, P = 0.000). The results also showed that the positive effect of MVF on pain, disability, dexterity, and range of motion was significantly greater than that of controls (P 0.05). Conclusion: MVF, in conjunction with traditional rehabilitation programs, may lead to greater improvements in pain, disability, placing dexterity, and range of motion. But it seems not to be effective on pinch and grip power and turning dexterity. © The Author(s) 2018

Root coverage procedures for treating single and multiple recession‐type defects: An updated Cochrane systematic review

BACKGROUND: This updated Cochrane systematic review (SR) evaluated the efficacy of different root coverage (RC) procedures in the treatment of single and multiple gingival recessions (GR). MATERIAL AND METHODS: We included randomized controlled trials (RCTs) only of at least 6 months' duration evaluating Miller's Class I or II GR (≥ 3 mm) treated by means of RC procedures. Five databases were searched up to January 16, 2018. Random effects meta-analyses were conducted thoroughly. RESULTS: We included 48 RCTs in the SR. The results indicated a greater GR reduction for subepithelial connective tissue grafts (SCTG) + coronally advanced flap (CAF) compared to guided tissue regeneration with resorbable membranes (GTR rm) + CAF (mean difference [MD]: -0.37 mm). There was insufficient evidence of a difference in GR reduction between acellular dermal matrix grafts (ADMG) + CAF and SCTG + CAF or between enamel matrix derivative (EMD) + CAF and SCTG + CAF. Greater gains in the keratinized tissue width (KTW) were found for SCTG + CAF when compared to EMD + CAF (MD: -1.06 mm), and SCTG + CAF when compared to GTR rm + CAF (MD: -1.77 mm). There was insufficient evidence of a difference in KTW gain between ADMG + CAF and SCTG + CAF. CONCLUSIONS: SCTG, CAF alone or associated with another biomaterial may be for treating single or multiple GR. There is also some evidence suggesting that ADMG appear as the soft tissue substitute that may provide the most similar outcomes to those achieved by SCTG
