background: alzheimer’s disease (ad) is characterized by progressive neuronal loss in hippocamp. epidermal neural crest stem cells (epi-ncsc) can differentiate into neurons, astrocytes and oligodendrocytes. the purpose of this study was to evaluate the effects of transplanting epi-ncsc into ad rat model. methods: two weeks after induction of ad by injection of amyloid-β 1-40 into ca1 area of ra...

An R-module M is called epi-retractable if every submodule of MR is a homomorphic image of M. It is shown that if R is a right perfect ring, then every projective slightly compressible module MR is epi-retractable. If R is a Noetherian ring, then every epi-retractable right R-module has direct sum of uniform submodules. If endomorphism ring of a module MR is von-Neumann regular, then M is semi-...

Methyl jasmonate and Epi-brassinolide as plant growth regulators have significant biological effects on plant growth, including increased tolerance to salt stress in plants. In this study, the effects of salinity stress and its interaction with methyl jasmonate and Epi-brassinolide on chlorophyll concentration, rate of photosynthesis, transpiration, stomatal conductance and resistance and chlor...

Background: Alzheimer’s disease (AD) is characterized by progressive neuronal loss in hippocamp. Epidermal neural crest stem cells (EPI-NCSC) can differentiate into neurons, astrocytes and oligodendrocytes. The purpose of this study was to evaluate the effects of transplanting EPI-NCSC into AD rat model. Methods: Two weeks after induction of AD by injection of Amyloid-β 1-40 into CA1 area of ra...

BACKGROUND Implementation of DWI in the abdomen is challenging due to artifacts, particularly those arising from differences in tissue susceptibility. Two-dimensional, spatially-selective radiofrequency (RF) excitation pulses for single-shot echo-planar imaging (EPI) combined with a reduction in the FOV in the phase-encoding direction (i.e. zooming) leads to a decreased number of k-space acquis...

BACKGROUND AND PURPOSE The different sensitivities to vessel size of gradient-echo echo-planar imaging (GE-EPI) and spin-echo EPI (SE-EPI) might indicate the relative cerebral blood volumes (rCBVs) of different tumor sizes. The techniques of GE-EPI and SE-EPI were compared for detecting low- versus high-grade gliomas. METHODS Six patients with low-grade gliomas and 19 patients with high-grade...

OBJECTIVE The purpose of this study was to compare the image quality of standard single-shot echo-planar imaging (ss-EPI) and that of readout-segmented EPI (rs-EPI) in patients with breast cancer. MATERIALS AND METHODS Seventy-one patients with 74 breast cancers underwent both ss-EPI and rs-EPI. For qualitative comparison of image quality, three readers independently assessed the two sets of ...

252x252 (left) and 384x384 (right). SAP-EPI and RS-EPI datasets were acquired in equivalent scan times of 1:24min/volume. Fig 3: (a) Scan-timenormalized noise maps (i.e. accounting for the maximum number of slices) of distortion-correctedSAP-EPI and RS-EPI calculated over six b = 0 scans (matrix size=384). (b) A RSEPI 384 image is blurred by a Gaussian kernel to achieve the same SNR as SAPEPI, ...

The experiments described in this paper were designed to determine the mechanism underlying the increase in 8-isoprostaglandin F(2alpha) (8-epi-PGF(2alpha)) production by cultured human endothelial cells during reoxygenation following hypoxia. Human umbilical artery endothelial cells were grown on microcarrier beads and exposed to sequential periods of normoxia, hypoxia, and reoxygenation. The ...

PURPOSE To analyze the levels of β-glucuronidase during prolonged (14 day) corneal preservation with epithelialized (EPI) and deepithelialized (DEP) corneas and the effect of supplemental hydrocortisone (HCT) on these levels. METHODS Thirty-six freshly excised bovine corneas were preserved in Optisol solution (4°C) for 14 days with the following conditions EPI/no supplemental HCT, DEP no supp...
