This study examined the efficacy of peak-power estimation equations in children using force platform data and determined whether allometric modeling offers a sounder alternative to estimating peak power in pediatric samples. Ninety one boys and girls aged 12-16 years performed 3 countermovement jumps (CMJ) on a force platform. Estimated peak power (PP(est)) was determined using the Harman et al...

In a series of studies we examined sensory evoked potentials to stimuli presented while subjects performed a primary task. The primary tasks were designed to induce changes in slow cortical potentials (SCP) such as P300, contingent negative variation (CNV), and postimperative negative variation (PINV). Brief auditory stimuli were presented before, during or after the primary task. The interacti...

During the period 1968-1974, 45 children with suspected neurodegenerative syndromes underwent brain biopsy of the right frontal lobe. The histological examination was normal in 44% and nonspecifically abnormal in 43% of the specimens. In 13% a specific histological abnormality was found, namely 3 with spongy degeneration, 1 Alexander's leucodystrophy, 1 metachromatic leucodystrophy, and 1 pachy...

—————————————————— Combining the results of tunneling, photoemission and thermodynamic studies, the pseudogap is unambiguously demonstrated to be caused by Van Hove nesting: a splitting of the density of states peak at (π, 0). The fact that the splitting remains symmetric about the Fermi level over an extended doping range indicates that the Van Hove singularity is pinned to the Fermi level. De...

The blood brain barrier (BBB) refers to the complex anatomical barrier in the brain composed of endothelial cells, astroglia, pericytes, perivascular macrophages and basal lamina. Its selectivity controls the entry of substances into the Central Nervous System (CNS) [1]. BBB disruption affects neurodegeneration [2] and in some cases can be harnessed to deliver intravenous therapeutics to the CN...

Health Programs paints a different picture. In a retrospective case control study, Paris and Canavan compared 32 anesthesiologists with 36 physician controls, and after an average follow-up of 7.5 yr, there was no difference in the relapse rates between these 2 groups. Likewise, the outcomes of residents did not differ from attending physicians. A similar report from Pelton involving 255 physic...

The present study was carried out to explore the effects of oolong and green teas on improving the memory deficits and brain pathological changes in senescence accelerated-prone mice P8 (SAMP8). Six-month-old mice were supplied with oolong tea, green tea or water as the sole drinking fluid for 16 wk. The memory ability of mice was evaluated by passive and active avoidance tests, while the exten...

OBJECTIVE To describe the distribution of elastic fibres in the developing male urethra and to provide stereological data of the concentration of elastic fibres in the human urethra. MATERIALS AND METHODS Urethras were obtained from 10 fresh normal human fetuses at 15-36 weeks of gestation. A place-matched spongy urethra of a 27-year-old normal adult man was also analysed. Samples were fixed ...

atherosclerosis is the most common cause of myocardial infarction and ischemic stroke. various risk factors have been identified for atherosclerosis. recently, bacterial and viral organisms, which are involved in chronic inflammatory processes, have been also implicated in atherosclerosis development. individuals with a prior history of periodontal diseases and/or tooth loss are considered to be...
