BACKGROUND Theoretically, sensory nerve action potential (SNAP) of the superficial peroneal nerve (SPN) should be preserved when L5 roots are damaged. Previous study indicated that SNAP of SPN was lost or reduced in amplitude in patiens with L5 radiculopathy. To address this issue, this study compared results of SPN sensory conduction studies between healthy subjects and patients with L5 radicu...
UNLABELLED It remains a matter of controversy as to whether cerebral perfusion declines with healthy aging. In vivo imaging with PET permits quantitative evaluation of brain physiology; however, previous PET studies have inconsistently reported aging reductions in cerebral blood flow (CBF), oxygen metabolism, and glucose metabolism. In part, this may be because of a lack of correction for the d...
the purpose of this study was to investigate the effect of task repetition on accuracy of iranian efl learners ’speaking ability. in order to achieve this purpose, a null hypothesis was developed: there is no statistically significant difference between accuracy speaking ability in iranian efl learners by use of task repetition. ; of course i should mention that, beside this null hypothesis, an...
The adaptive response of maximal aerobic power (VO2max) to endurance exercise training was compared in 53 men and 57 women, aged 60-71 yr. The subjects were healthy and had been sedentary for at least 2 yr. Pretraining VO2max was measured during graded treadmill walking on two occasions. These values were reproducible (24.4 +/- 4.7 vs. 24.4 +/- 4.6 (SD) ml.min-l.kg-1; r = 0.96). Subjects traine...
BACKGROUND Different measurements are used to assess shoulder function, including range of motion, strength, functional performance and self-report function. To understand disablement, it is necessary to understand the relationship between impairments and function in persons without shoulder problems. This study was conducted to enhance existing comparative data in subjects without upper extrem...
BACKGROUND This pilot trial was designed to determine if an optimal dose of Technosphere(®) insulin (TI) inhalation powder (MannKind Corp., Valencia, CA) could be used regardless of variation in meal carbohydrate (CHO) content. SUBJECTS AND METHODS In total, eight subjects (seven men, one woman) with type 2 diabetes were enrolled. Subjects underwent dose optimization meal challenge (MC) visit...
BACKGROUND Sputum induction is becoming more commonly used to assess airway inflammation. Since it is a relatively non-invasive procedure it may be useful for repeated measurements over a short period of time. METHODS To assess the repeatability of the method over a 24 hour period, eight healthy, non-smoking, non-atopic subjects (four men) of mean age 30 years underwent sputum induction, repe...
Structural variations are among the most frequent interindividual genetic differences in the human genome. The frequency and distribution of de novo somatic structural variants in normal cells is, however, poorly explored. Using age-stratified cohorts of 318 monozygotic (MZ) twins and 296 single-born subjects, we describe age-related accumulation of copy-number variation in the nuclear genomes ...
STUDY DESIGN Two-factor mixed-design study, with factors including group (control and noncoper) and task (sidestep, crossover, and straight). OBJECTIVES To compare the knee and hip joint angles and moments of control subjects and subjects with an anterior cruciate ligament (ACL) deficient knee classified as noncopers, during a sidestep, crossover, and straight-ahead task. BACKGROUND Subject...
