CoFeCu nanowires were deposited by pulsed electrodeposition technique into the porous alumina templates by a two-step mild anodization technique, using the single-bath method. The electrodeposition was performed in a constant electrolyte while Cu constant was controlled by electrodeposition current. The electrodeposition current was 3.5, 4.25, 5 and 6 mA. The effect of electrodeposition current...

In clinical research, parameters required for sample size calculation are usually unknown. A typical approach is to use estimates from some pilot studies as the true parameters in the calculation. This approach, however, does not take into consideration sampling error. Thus, the resulting sample size could be misleading if the sampling error is substantial. As an alternative, we suggest a Bayes...

The present study, wants to highlight and review the most prevalent disease amongst travelers. In the current review, an updated review regarding epidemiology, involved pathogens, and a brief review of current evidence-based guidelines for prevention and treatment of this disease are provided. A distinguishing feature of the current review is the discussion of the impacts of irritable bowel syn...

The current study was carried out to determine the sero-prevalence and molecular detection of Brucella species in persons involved in pork production in Punjab state of India. The sample size was selected using survey toolbox and a total of 123 blood samples were collected from pig farmers and slaughter house workers. The serum samples were tested using Rose Bengal Plate Test (RBPT), Standard T...

Objective: This study aimed to describe methodological challenges encountered in designing a follow-up assessment of US Army Soldiers who served in Operation Iraqi Freedom. Study Design and Setting: The Neurocognition Deployment Health Study (NDHS) enrolled 1595 soldiers at 2 military installations, starting in 2003. Prior work compared predeployment and postdeployment assessments among Iraq-de...

The current research investigated the factors influencing the waiting time in the emergency department (ED) in King Fahd Armed Forces Hospital in Jeddah city, Saudi Arabia. We have decided to evaluate the impact of multiple factors in the waiting time in the ED. These factors are derived from three main variables. The independent variables include the organizational, management and staffing fac...

BACKGROUND So far, no comprehensive answer has emerged to the question of whether transcranial direct current stimulation (tDCS) can make a clinically useful contribution to the treatment of major depression. We aim to present a systematic review and meta-analysis of tDCS in the treatment of depression. METHOD Medline and Embase were searched for open-label and randomized controlled trials of...

OBJECTIVE To investigate the feasibility and safety of a combined anodal transcranial direct current stimulation (tDCS) and dual task gait training intervention in people with Parkinson's Disease (PD) and to provide data to support a sample size calculation for a fully powered trial should trends of effectiveness be present. DESIGN A pilot, randomized, double-blind, sham-controlled parallel g...

Background Speech-related problems are common in Parkinson's disease (PD), but there is little evidence for the effectiveness of standard speech and language therapy (SLT) or Lee Silverman Voice Treatment (LSVT LOUD®). Methods The PD COMM pilot was a three-arm, assessor-blinded, randomised controlled trial (RCT) of LSVT LOUD®, SLT and no intervention (1:1:1 ratio) to assess the feasibility an...

Is OSA Associated with a Decline in NCF? The data regarding associations between OSA and a NCF decline are mixed. Some of the limitations of evaluating existing studies in the literature are that a majority have small sample sizes, a diverse group of NCF tests and protocols have been reported, and in the case of controlled trials, different shams or placebos have been utilized. There are severa...
