Introduction Over the last decades, considerable levels of electromagnetic fields (EMFs) have been characterized in the living environment. Recent epidemiological studies on occupational and residential exposure to EMF have shown that 50/60 Hz fields, known as extremely low frequencies (ELF), have various biological effects, such as angiogenesis. This study aimed to investigate the effect of en...

BACKGROUND Mechanical loading is known to play an important role in bone remodelling. This study aimed to evaluate the effect of high- and low-frequency axial loading, applied directly to the implant, on peri-implant bone healing and implant osseointegration. METHODOLOGY Titanium implants were bilaterally installed in rat tibiae. For every animal, one implant was loaded (test) while the other...

OBJECTIVE To evaluate the effects of prone and supine sleeping positions on electrocortical activity during active (AS) and quiet (QS) sleep in low birthweight infants. DESIGN Randomised/crossover study. SETTING Infant Physiology Laboratory at Children's Hospital of New York. PATIENTS Sixty three healthy, growing, low birthweight (birth weight 795-1600 g) infants, 26-37 weeks gestational ...

in the recent years, the coherence index is used in many electroencephalographic studies for investigation of brain connectivity in children with adhd disorder. it is suggested that the coherence is a useful index in discrimination of adhd subjects from normal subjects. however, a few studies are accomplished in subtypes of adhd to identify of differences in functional connectivity between adhd...

Electrical stimulation offers the potential to develop novel strategies for the treatment of refractory medial temporal lobe epilepsy. In particular, direct electrical stimulation of the hippocampus presents the opportunity to modulate pathological dynamics at the ictal focus, although the neuroanatomical substrate of this region renders it susceptible to altering cognition and affective proces...

introduction: on the importance of the formant frequency, it is enough to say that the first three formants of a vowel and their internal relationships are the major components in detection of vowel type by listener. moreover, the quality of a vowel depends on its factorial frequencies. the main application of measuring factorial frequency is for description of vowel errors because recognizing ...

The study investigated the effects of pulsed electromagnetic fields (PEMFs) of different frequencies on the gene expression of receptor activator of nuclear factor kappa B (RANK) and Nuclear factor of activated T-cells cytoplasmic 1 (NFATc1) in rat osteoblast and osteoclast co-cultured model. Osteoblast-like cells were isolated from calvariae of Newborn Sprague Dawley rats (SD rats), while oste...
