background: in general, 15% of oocytes collected in art cycles are immature. these oocytes may be cryopreserved further for use in in-vitro maturation (ivm) program. objective: the aim of this study was to determine maturation capacity, morphometric parameters and morphology of human immature oocytes in both fresh ivm (fivm) and vitrified-ivm (vivm) oocytes. materials and methods: 93 women who ...

An important aspect of the fear response is the allocation of spatial attention toward threatening stimuli. This response is so powerful that modulations in spatial attention can occur automatically without conscious awareness. Functional neuroimaging research suggests that the amygdala and anterior cingulate cortex (ACC) form a network involved in the rapid orienting of attention to threat. A ...

This study compared sensitivity of FDG-PET, MR morphometry, and diffusion tensor imaging (DTI) derived fractional anisotropy (FA) measures to diagnosis and memory function in mild cognitive impairment (MCI). Patients (n=44) and normal controls (NC, n=22) underwent FDG-PET and MRI scanning yielding measures of metabolism, morphometry and FA in nine temporal and parietal areas affected by Alzheim...

PURPOSE OF REVIEW In contrast to traditional anatomical and pathological methods, magnetic resonance morphometry of the brain allows the in-vivo study of temporal changes in brain morphology and the correlation of brain morphology with brain function. Magnetic resonance morphometry has thereby recently emerged as one of the most promising fields in clinical neuroscience. This review covers the ...

Monodisperse aerosol particles can be used to non-invasively probe intrapulmonary airspace dimensions. In this study, the aerosol-derived airway morphometry technique was used to study airspace dimensions in 79 healthy subjects, in order to assess reference data for the future clinical application of aerosol-derived airway morphometry, and to investigate the effect of lung inflation, anthropome...

Voxel-Based MR-Morphometry and Diffusion Tensor Imaging: Basics and Applicability in Clinical Neurology. The potential and clinical options are presented which originate from the clinical application of computer-based magnetic resonance imaging (MRI) techniques such as voxel-based morphometry (VBM) to human brain grey and white matters as

background copper (cu) is an essential trace element involved in normal reproduction but its overexposure may produce some detrimental effects. the aim of this study was to investigate the effects of copper sulfate poisoning on morphometery of mice ovarian structures and probable intracellular changes. methods thirty mature female mice were randomly allocated to control and two treatment groups...

the aim of this study was to examine the possible morphological and morphometric changes resulting from vitrification of embryos at the cleavage stage. in this study, 30 mice early-cleavage embryos at different stages of cleavage, resulting from in vitro fertilization (ivf) techniques, were examined before and after vitrification. digital images were taken from embryos before and after vitrific...

quantitative histology of the descended testis of unilateral cryptorchid bucks was compared with testis of normal bucks to evaluate the reproductive potentials of the scrotal testis in unilateral cryptorchids, using light microscopy techniques. the contralateral scrotal testes of the unilateral cryptorchids and the testes of the normal bucks contained profiles of seminiferous epithelium and eac...

morphometrical study of iranobuthus krali (kovarik,1997) is given on the basis of 6 specimens collected from fars province,southern iranthe specimens was captured by forceps under uv light during field studies in this province.iranobuthus is easily distinguished from compsobuthus vachon,1949 by it's size and it differs from genera androctonus hemprich & ehremberg, 1828 hottentotta and mesob...
