Subject performance

Additional evidence to support this claim comes from the fact that there was a significant correlation between subjects performance on the ToM tasks and their scores on an attributional scale questionaire. This showed that individuals who tended to make more errors on the ToM tasks were also more likely to misattribute the blame for any unfortunate events that befell them, being prone to blaming others rather than themselves or unavoidable environmental events. 

Some functional neuroimaging studies have examined the effects of scopolamine in cognitive tasks. Although scopolamine inhibits increases in cerebral blood flow to somatosensory stimulation, it does not inhibit the neural response (Ogawa et al. 1994). Thus, cholinergic systems may be involved in coordination of cerebral blood flow increases to neural activation. Subjects performing an attentional auditory discrimination...

With the non-invasive tool of muscular proton MR spectroscopy it is possible to study lipid oxidation, especially oxidation of IMCL, during exercise much more comfortably and precisely. Boesch et al revealed a decrease of IMCL in one subject performing a mountain bike ride over 3 h at about 70% of V02max, for the first time suggesting that IMCL are metabolized during this form of exercise.

Early clinical studies are performed in cancer patients in hospitals instead of healthy volunteers, and in specialized Phase I units. Selection criteria for patients entered into cetuximab Phase I studies included various important factors such as disease state, life expectancy (>3 months), prior treatment, organ function, age, tumor type and target (i.e., EGFR expression). Therefore, pharmacokinetic (PK) data obtained from these individuals is confounded by numerous factors, a fact usually absent in conventional studies with tightly controlled, well-selected healthy subjects performed for non-oncologic drags. 

In a series of studies, Bell et al. assessed the effects of ephedrine mixtures on performance, and found measurable improvement. One and one-half hours after ingesting a placebo (P), caffeine (C) (4 mg/kg), ephedrine (E) (0.8 mg/kg), or caffeine and ephedrine, 12 subjects performed a 10-km run while wearing a helmet and backpack weighing 11 kg. The trials were performed in a climatic suite at 12-13°C, on a treadmill where the speed was regulated by the subject. V02, VC02, V(E), HR, and rating of perceived exer-...

Each subject was tested on two fine-motor tasks, the Grooved Pegboard Test (GPT), which assesses visual-motor coordination, and the Static Motor Steadiness Test (SMST), which assesses hand steadiness. Each subject performed the task first with the dominant hand and then with the nondominant... 

After the samples were collected, subjects performed a surgical scrub with a 4% CHG product for 4 minutes and then washed their hands with 70% isopropyl alcohol for one minute and air-dried them for an additional 5 minutes. Note All hand sampling was conducted utilizing the glove juice sampling method. 

If a chemist were to be granted one wish, it might be to actually wimess, in all of its discrete steps, the transformation of reactant molecules into product molecules. Aside Ifom the sheer enjoyment of watching their subjects perform, the observations would lead to a more profound under-... 

If you have time during the day, twenty- to thirty-minute power naps appear to help prevent information burnout or frustration, irritation, and poorer performance on mental tasks. In one study on napping sponsored by the National Institutes of Health, subjects performed four daily practice sessions of a visual task.5 As fatigue set in, their scores dropped over the sessions. But for those who took a thirty-minute nap after session number two, their scores declined no further. Subjects who took a one-hour nap at that point actually boosted their performance in the third and fourth sessions. 

A brief, task-oriented study in which subjects performed typical operations in and near treated oases for one-hour intervals while wearing PSP s showed no detectable levels. Insufficient data are available to speculate as to what events and of what duration are necessary to produce periodic exposures exceeding even 1 ppm.
