CONTEXT Carbohydrate (CHO) and caffeine (CAF) both improve endurance performance. PURPOSE To determine by systematic literature review coupled with meta-analysis whether CAF ingested with CHO (CHO+CAF) improves endurance performance more than CHO alone. METHODS Databases were searched using the keywords caffeine, endurance, exercise, carbohydrate, and performance. Criteria for inclusion wer...

The aim of this study was to investigate the influence of serial mouth rinsing (MR) with nutritional supplements on cognitive performance (i.e., cognitive control and time perception) during a 40-min submaximal exercise. Twenty-four participants completed 4 counterbalanced experimental sessions, during which they performed MR with either placebo (PL), carbohydrate (CHO: 1.6 g/25 mL), guarana co...

The Complex Ambiguity Function (CAF) used in emitter location measurement is a 2-dimensional complex-valued function of time-difference-of-arrival (TDOA) and frequency-difference-of-arrival (FDOA). In classical TDOA/FDOA systems, pairs of sensors share data (using compression) to compute the CAF, which is then used to estimate the TDOA/FDOA for each pair; the sets of TDOA/FDOA measurements are ...

There is a need to identify biomarkers that predict degree of chronic speech fluency/language impairment and potential for improvement after stroke. We previously showed that the Arcuate Fasciculus lesion load (AF-LL), a combined variable of lesion site and size, predicted speech fluency in patients with chronic aphasia. In the current study, we compared lesion loads of such a structural map (i...

Caffeine (Caf) ingestion increases plasma epinephrine (Epi) and exercise endurance; these results are frequently transferred to coffee (Cof) consumption. We examined the impact of ingestion of the same dose of Caf in Cof or in water. Nine healthy, fit, young adults performed five trials after ingesting (double blind) either a capsule (Caf or placebo) with water or Cof (decaffeinated Cof, decaff...

while parkinson's disease (pd) has traditionally been defined by motor symptoms, many researches have indicated that mild cognitive impairment is common in non-demented pd patients. the purpose of this study was to compare verbal fluency performance in non-demented parkinson's disease patients with healthy controls.in this cross-sectional study thirty non-demented parkinson's disease patients a...

This study aimed to investigate the impact of task sequencing, along +/- reasoning demands dimension, on writing task performance in terms of accuracy.  The study was motivated by Robinson’s Cognition Hypothesis (CH) as well as previous studies investigating the relationships between task complexity and second language production. The participants of the study were 90 intermediate students at t...

Like humans, monkeys can make accurate judgements about their own memory by reporting their confidence during cognitive tasks. Some have suggested that animals use associative learning to make accurate confidence judgements, while others have suggested animals directly access and estimate the strength of their memories. Here we test a third, non-exclusive possibility: perhaps monkeys, like huma...

background: coronally advanced fl ap (caf) has been shown to effectively treat gingival recession. platelet rich plasma (prp), containing autologous growth factors, has been shown to promote soft tissue healing. the aim of this clinical study was to determine whether the addition of an autologous prp to a caf when compared to a caf alone would improve the clinical outcome for treatment of multi...
