Patients with Attention-Deficit/Hyperactivity Disorder (ADHD) and obsessive/compulsive disorder (OCD) share problems with sustained attention, and are proposed to share deficits in switching between default mode and task positive networks. The aim of this study was to investigate shared and disorder-specific brain activation abnormalities during sustained attention in the two disorders. Twenty ...

BACKGROUND It remains unclear if certain antiretroviral medications, particularly abacavir, compromise response to HCV therapy. Such data could inform the selection of appropriate antiretrovirals in HIV/HCV-coinfected patients. The aim of this study was to determine if use of abacavir, as well as other antiretrovirals, was associated with reduced response to pegylated interferon (PEG-IFN) plus ...

Objectives: The aim of the study was to investigate the effects of different loads on tremor around 10 Hz during fatiguing contractions. Methods: Eighteen healthy volunteers performed sustained isometric knee extensions at 30%, 50% and 70% maximum voluntary contraction (MVC). During the fatiguing contractions, mechanical recordings were made with a high-resolution force sensor. Tremorpower was ...

This paper presents the results of an experimental study on flexural behavior carbon fibre reinforced polymer (CFRP) anchorage system strengthened concrete (RC) beams under coupled effects corrosion damage and sustained loading. The test were subjected to combined accelerated in 5% NaCl solution loads for 25, 50 100 days at 0% 50% load levels virgin beam ultimate capacity. failure modes, carryi...

Polylactide (PLA) polymer particles entrapping tetanus toxoid (TT) were evaluated in terms of particle size, antigen load, dose and additional adjuvant for achieving high and sustained anti-TT antibody titer from single point intramuscular immunization. Admixture of polymer entrapped TT and alum improved the immune response in comparison to particle-based immunization. High and long lasting ant...

The objective was to better understand how a series compliance alters contraction kinetics and power output of muscle to enhance the work done on a load. A mathematical model was created in which a gravitational point load was connected via a linear spring to a muscle (based on the contractile properties of the sartorius of leopard frogs, Rana pipiens). The model explored the effects of load ma...

The present study aimed to delineate the extent to which unitary executive functions might be shared across the separate domains of episodic and working memory. A mixed blocked/event-related functional magnetic resonance imaging (fMRI) design was employed to assess sustained (tonic control) and transient (phasic control) brain responses arising from incrementing executive demand (source versus ...

previous studies have reported the efficacy of baclofen in the treatment of gastroesophageal reflux diseases (gerd). the objective of present study is to evaluate the effect of co-administration of omeprazole 20 mg/d plus sustained release baclofen (sr baclofen) vs omeprazole 20 mg/d plus placebo on alleviation of symptoms in patients with a diagnosis of gerd. a prospective, double blind, place...

In the United States, an estimated 1.2 million persons are living with human immunodeficiency virus (HIV), a serious infection that, if untreated, leads to illness and premature death. Persons living with HIV who use antiretroviral therapy (ART) and achieve very low levels of the virus (suppressed viral load) can have a nearly normal life expectancy and have very low risk for transmitting HIV t...
