Differentiation between Parkinson's disease (PD) and other neurodegenerative disorders with parkinsonian features, such as multiple system atrophy (MSA), progressive supranuclear palsy (PSP), and cort…
To gain insight into the synergistic control of hand muscles, we have recently quantified the strength of correlated neural activity across motor units from extrinsic digit flexors during a five-digit…
PURPOSE: SPECT is an important diagnostic tool for dementia. Recently, statistical analysis of SPECT has been commonly used for dementia research. In this study, we evaluated the accuracy of visual SP…
OBJECTIVE: The aim of the study was to compare the effects of progressive reducing assistance force versus full assistance force controlled robot-assisted gait training combined with conventional phys…
Conventional signal processing typically involves frequency selective techniques which are highly inadequate for nonstationary signals. In this paper, we present an approach to perform time-frequency …
This article presents a new spatio-temporal method for M/EEG source reconstruction based on the assumption that only a small number of events, localized in space and/or time, are responsible for the m…
Ferritin is an iron cage having protein, capable of extracting metal ions in their cages and a consequence of the electron transfer of metal ions in their cage by reduction and oxidation processes, el…
UNLABELLED: The distribution of benzodiazepine receptors in the human brain has been widely studied with SPECT using (123)I-iomazenil and semiquantitative approaches, but these methods do not allow qu…
We compare the spectral indices of photoplethysmogram variability (PPGV) estimated using photoplethysmograms recorded from the earlobe and the middle fingers of the right and left hand and analyze the…
PURPOSE: Fibroblast growth factor-2 (FGF2) has been implied in the development of myopia according to previous studies investigating FGF2 in the sclera and retinal pigment epithelium. This study measu…
Intra-axial pseudotumors in the central nervous system often mimic malignant brain tumors and cause difficulty in diagnosis and treatment. The present study investigates their radiologic and histologi…
BACKGROUND: Atherosclerosis imaging by multidetector computed tomography (MDCT) detects coronary artery plaque extent, distribution, location and composition. In contrast, functional imaging by single…
OBJECTIVE: To study the association between cytochrome P450 2A6 (CYP2A6) genotype and metabolism of nicotine to cotinine, identify functional polymorphisms, and develop a predictive genetic model of n…
Regional cerebral blood flow (rCBF) was evaluated quantitatively by 99mTc hexamethyl propyleneamine oxime and single photon emission CT (SPECT) during the interictal phase in 52 patients with focal ep…
CONTEXT: Relatively little is known about genetic determinants of cognitive dysfunction in schizophrenia. Recent studies suggest that a brain-derived neurotrophic factor (BDNF) prodomain single nucleo…
Wistar rats with non-insulin dependent diabetes induced by neonatal streptozotocin (STZ) administration were raised either in large or in small litters. The STZ-treated rats from small litters showed …
BACKGROUND AND AIM: Scatter from the bowel degrades image quality in 99mTc sestamibi myocardial perfusion imaging (MPI). Iodinated oral contrast, which has been used to outline bowel in medical imagin…
The fluid and solute transport properties of pleural tissue were studied using specimens of intact visceral pleura from adult sheep lungs. After thoracotomy, a shallow incision through the pleural sur…
This article introduces a method and step-by-step instructions for the design of a low-cost, flexible electrogoniometer, suitable for kinesiology, rehabilitation, and biometric applications. Two unidi…
BACKGROUND: Labyrinthine Aplasia, Microtia and Microdontia (LAMM) syndrome is characterized by the complete absence of inner ear structures (Michel aplasia), microtia and microdontia. Hypophosphatemic…
