The aim of the present study is to investigate the relationship between linear and non-linear activities in human electroencephalograms (EEGs) by examining the linear lateral asymmetry index and the correlation dimension as a non-linear measure of complexity and to typify the characteristics of EEGs between schizophrenic patients and normal controls. We recorded the EEG from 16 electrodes in 10...

The present study was undertaken to assess the skeletal craniofacial asymmetry in South Indian population by a posteroanterior cephalometric radiographic method. The skeletal craniofacial structures on one side of the face were compared with that of the other, by drawing various triangles representing different craniofacial regions. The sample consisted of 60 subjects (30 males and 30 females) ...

Background: Karyotype analysis has been the standard and reliable procedure for prenatal cytogenetic diagnosis since the 1970s. However, the major limitation remains requirement for cell culture, resulting in a delay of as much as 14 days to get the test results.CGH array technology has proven to be useful in detecting causative genomic imbalances or genetic mutations in as many as 15% of child...

OBJECTIVE To review the relationship between congenital heart defects and chromosomal abnormalities detected by the karyotype. DATA SOURCES Scientific articles were searched in MEDLINE database, using the descriptors "karyotype" OR "chromosomal" OR "chromosome" AND "heart defects, congenital". The research was limited to articles published in English from 1980 on. DATA SYNTHESIS Congenital ...

Objective To compare the roles of fluorescence in situ hybridization (FISH) and karyotype analysis on chorionic villus in spontaneous abortion. Methods A total of 201 cases were included in this study and were randomly divided into 2 groups by the same gestational age. The villi from 100 cases (group A) were cultured and used for karyotype analysis, while the uncultured villi from 101 women (gr...

Objectives: Fear of falling (FOF) is a common complication after stroke affecting gait and balance performance in individuals with a history of stroke. The current study aimed at determining the influence of the level of FOF on gait and balance performance after chronic stroke. Methods: A total of 76 persons with chronic stroke (including 41 women), who had no cognitive impairment and could wa...

in this study, for the first time in iran, the karyotype of bigmouth lotak, cyprinion macrostomum heckel, 1843, was investigated through examining metaphase chromosomes of seven fish with mean weight 30±5g caught by electrofishing from godarkhosh river in ilam province. to stimulate cell divisions, fish were injected intraperitoneally two times by phytohemagglutinin (pha). the cell divisions we...

Maintaining the body underwater in the so-called vertical position, where the body is inverted (head down) and balanced, is made possible by performing the support scull movement by the upper limbs. In synchronized swimming, the main criteria for judging this vertical position are maintaining body stability and the maximum height of the lower limbs one is able to extend out of the water. Theref...

We establish a quantitative isoperimetric inequality in higher codimension. In particular, we prove that for any closed (n − 1)-dimensional manifold Γ in Rn+k the following inequality D(Γ) ≥ Cd(Γ) holds true. Here, D(Γ) stands for the isoperimetric gap of Γ, i.e. the deviation in measure of Γ from being a round sphere and d(Γ) denotes a natural generalization of the Fraenkel asymmetry index of ...
