This study aimed to evaluate the concentration of heavy metals in liquid effluents and to quantify the mercury content in dental amalgam waste generated by dental clinics. Three neighbouring cities in Northeast Algeria were considered in this study (Constantine, Skikda, and Annaba). Heavy metals, such as Hg, Cu, Zn, Fe, Ni, Mn, Cr, Cd, and Pb, were analysed in wastewater and then compared with ...

OBJECTIVES To assess the time course changes in N-acetylaspartate (NAA) and creatine (Cr) levels in the brain of athletes who suffered a sport-related concussion. PARTICIPANTS Eleven nonconsecutive athletes with concussive head injury and 11 sex- and age-matched control volunteers MAIN OUTCOME MEASURES : At 3, 15, 30, and 45 days postinjury, athletes were examined by proton magnetic resonan...

BACKGROUND In Japan, Job assistance for SMI have been not active. Compared with mental retardation, employment rate of SMI was low. The needs of the effective job assistance for SMI are growing. The purpose of this study was to determine the effectiveness of the combination approach of Cognitive Remediation (CR) and Supported Employment (SE) in clinical outcomes, including cognitive functioning...

Ioannidis estimated that most published research findings are false, but he did not indicate when, if at all, potentially false research results may be considered as acceptable to society. We combined our two previously published models to calculate the probability above which research findings may become acceptable. A new model indicates that the probability above which research results should...

introduction: this cross-sectional survey determined the dental prevalence of apical periodontitis (ap) in selected iranian population, and evaluated the influence of the quality of root canal treatment (rct) and their coronal restorations (cr) on the periapical status. materials and methods: a total of 1064 panoramic radiographies were evaluated by two observers during 2009. the quality of rct...

OBJECTIVES (1) Assess whether cardiac rehabilitation (CR) is a feasible and acceptable model of rehabilitation for postsurgical colorectal cancer (CRC) survivors, (2) evaluate trial procedures. This article reports the results of the first objective. DESIGN AND SETTING A pragmatic pilot randomised controlled trial with embedded qualitative study was conducted in 3 UK hospitals with CR facilit...

Creatine (Cr) supplementation increases muscle mass, strength, and power. Arginine a-ketoglutarate (A-AKG) is a precursor for nitric oxide production and has the potential to improve blood flow and nutrient delivery (i.e., Cr) to muscles. This study compared a commercial dietary supplement of Cr, A-AKG, glutamine, taurine, branched-chain amino acids, and medium-chain triglycerides with Cr alone...
