Assuming that higher dimensions existed in the early stages of the universe where the evolution was inflationary, we construct an open, singularity-free, spatially homogeneous and isotropic cosmological model to study the effects of dimensional reduction that may have taken place during the early stages of the universe. We consider dimensional reduction to take place in a stepwise manner and in...

Parkinson disease (PD) is a degenerative neurological disorder that affects 0.5- 1% of old people in western countries. It primarily affects mobility function, and associated with increasing disability over time. People with PD express bradykinesia, rigidity, tremor, progressive postural instability and muscle weakness as symptoms of PD. Various exercise programs, including resistance or aerobi...

Polyomaviruses may cause human disease, particularly in immunocompromised hosts. JCV, one of the members of polyomaviridae family, is the causative agent of the neurological disease progressive multifocal leukoencephalopathy (PML), which occurs mostly in immunocompromised patients. Progressive Multifocal leukoencephalopathy (PML) is a progressive demyelinating disorder of the central nervous sy...

The detrimental effects of velopharyngeal dysfunction (VPD) on speech intelligibility in persons with progressive motor speech disorders are poorly understood. In this study, we longitudinally investigated the velopharyngeal and articulatory performance of 142 individuals with varying severities of amyotrophic lateral sclerosis (ALS). Our goal was to determine the mechanisms that underlie the e...

the importance of knowing afterlife and resurrection is in its effects on human’s way in physical life and achieving prosperity or adversity in future life. flesh and spirit, the bases of human’s true nature, go through severe changes in an evolutionally trend. being aware of physical and spiritual perceptions and moving toward perfection leads human to eternal life. this internal wisdom result...

Both akinetic and hyperkinetic movement disorders may rarely be the presenting feature of human immunodeficiency virus (HIV) infection. The possible pathogenic basis is the involvement of subcortical structures by the HIV infection-related pathology. Opportunistic infections, or mass lesions complicating HIV infection. In addition dopaminergic dysfunction and medications may also play a role. W...

INTRODUCTION Sleep is a complex phenomenon characterized by important modifications throughout life and by changes of autonomic cardiovascular control. Aging is associated with a reduction of the overall heart rate variability (HRV) and a decrease of complexity of autonomic cardiac regulation. The aim of our study was to evaluate the HRV complexity using two entropy-derived measures, Shannon En...

We study correlation properties of the magnitude and the sign of the increments in the time intervals between successive heartbeats during light sleep, deep sleep, and rapid eye movement (REM) sleep using the detrended fluctuation analysis method. We find short-range anticorrelations in the sign time series, which are strong during deep sleep, weaker during light sleep, and even weaker during R...
