introduction : the  rapid development  of wireless telecommunication technologies  over the past decades, has led to significant changes in the exposure of the general public to electromagnetic fi elds. nowadays, people are continuously exposed to different sources of electromagnetic fi elds such as mobile phones, mobile base stations, cordless phones, wi-fi routers, and power lines. therefore,...

• duchenne muscular dystrophy o onset 3 to 5 yrs o clinical § weakness o distribution § proximal > distal § symmetric § legs & arms § most involved muscles: adductor magnus in legs § relatively spared muscles: gracilis & sartorius o course § reduced motor function by 2 to 3 years § steady decline in strength: after 6 to 11 years o gowers sign: standing up with the aid of hands pushing on knees ...

Since the initial report on the clinical value of serum glutamic oxalacetic transaminase (SGOT) determinations in the diagnosis of myocardial infarction (LaDue, Wroblewski, and Karmen, 1954), a considerable amount of work has been done on the blood levels of other enzymes liberated from necrosed heart cells. Because of lack of specificity and difficulty of estimation, very few other enzyme esti...

A rapid plantar flexion perturbation applied to the ankle during the stance phase of the step cycle during human walking unloads the ankle extensors and produces a marked decline in the soleus EMG. This demonstrates that sensory activity contributes importantly to the enhancement of the ankle extensor muscle activation during human walking. On average, the EMG begins to decline approximately 52...

Background and Objective: 2-arachidonoylglycerol (2-AG) and anandamide (AEA) are two major endocannabinoids. Using inhibitors of the enzymatic pathways involved in the elimination of 2-AG and AEA as well as synthetic 2-AG, we examined the effectiveness of these endocannabinoids on epileptiform activity induced in Wistar rats by pentylenetetrazol (PTZ). Material and Methods: Adult male Wistar r...

22 Even though interlimb coordination is critical in bipedal locomotion, the role of muscle 23 afferent mediated feedback is unknown. The aim of this study was to establish if ipsilateral 24 muscle generated afferent feedback can influence contralateral muscle activation patterns in 25 the human lower limb and to elucidate the mechanisms involved. 26 The effect of ipsilateral tibial nerve stimu...

abstract background: several studies have examined the reflex response of ankle musculature to sudden inversion in noninjured and injured subjects. to date, there have been no studies to determine the effect of versatile degrees & conditions of perturbation on the ankle musculature latency. the purpose of this study was to measure and determine whether there was a difference in ankle musculatur...

We present the implementation of a large-scale latency estimation system based on GNP and incorporated into the Google content delivery network. Our implementation employs standard features of contemporary Web clients, and carefully controls the overhead incurred by latency measurements using a scalable centralized scheduler. It also requires only a small number of CDN modifications, which make...

OBJECTIVES to investigate the effects of regular Tai Chi (TC) or jogging exercise on neuromuscular reaction in older people. DESIGN cross-sectional study. SETTING university biomechanics laboratory. SUBJECTS 21 long-term elderly TC practitioners were compared with 18 regular elderly joggers and 22 sedentary counterparts. MEASUREMENTS electromyography (EMG) was used to detect the neuromu...

OBJECTIVE A startling loud acoustic stimulus can involuntarily elicit planned movements, a phenomenon referred to as startReact. Following stroke, startReact elbow flexion in stroke survivors are improved from voluntary movements. Specifically, startReact elbow flexion in unimpaired individuals is not statistically different from stroke survivors in terms of onset latency and muscle activation ...
