Objective(s): Neurotrophic factors secreting cells (NTS-SCs) may be a superior cell source for cell-based therapy in neurodegenerative diseases. NTS-SCs are able to secrete some neurotrophic Such as nerve growth factor and glia-derived neurotrophic factor. Our primary aim was to assess transplantation of neurotrophic factor secreting cells derived from human adipose-derived stem cells (hADSCs) ...

A B S T R A C T Introduction: Even today there is no effective drug therapy to prevent neuronal loss after brain stroke. In the present study we studied the effect of mitochondrial KATP channel regulators on neuronal ultrastructure after ischemia reperfusion in the rat. Materials & Methods: Rats temporarily subjected to four vessels occlusion for 15 minutes followed by 24 hours reperfusion with...

The ultrastructure of huma corpora luntea obtained approximately 2, 3, 5, 11, and 15 days after ovulation is reported . All specimens were fixed in Karnovsky's formaldehyde-glutaraldehyde solution . The 5-day corpus luteum is presumed to represent, in terms of fine structure, the ultrastructural aspects of high progesterone production and is compared to younger differentiating and older regress...

The effects of the heavy metals lead (Pb) and cadmium (Cd) on the ultrastructure and the induction of Heat Shock Protein 70 (HSP 70) have been studied in Elodea canadensis Michx. As for the ultrastructural effects, sublethal concentrations of the metals caused alterations of the cell fine ultrastructure. Lead and cadmium induced alterations: chloroplast were swollen with altered thylakoid organ...

background: toxoplasmosis is one of the most common parasitic infections of humans and other mammals. this study was aimed to understand the mechanism of action of veterinary medicine-sulfachloropyrazine (spz, 99.97%) against toxoplasma gondii . methods: t. gondii tachyzoites were soaked in pbs (as a control) or spz (250 mg/ml) for 2 h at 37 °c. after being processed, any ultrastructural change...

The surface ultrastructure of normal rabbit epidermal, cells and Vx~ carcinoma cells was investigated by Coman and Anderson (3) by means of electron microscopy, using replica methods. They found differences between the two types of cells and concluded that a change in the ultrastructure of the cell surface accompanies the transformation from a normal to a carcinomatous state. I t is possible th...

The endometrial-myometrial interface (EMI) is a specific functional region of uterus. However, our knowledge on EMI ultrastructure both in normal uterus and adenomyosis is far from enough to understand its pathology. In this study, used the samples of EMI and outer myometrium (OM) from the adenomyosis hysterectomy specimens and the subjects from the control uteri, we prospectively compared the ...

Tichy F.: The ultrastructure of Taste Buds in the Newborn Lamb. Acta vet. Brno, 61, 1992: 83-91. The ultrastructure of taste buds on circumvallate papillae collected from the tongues of three lambs on the day of birth was studied. Of special concern were the composition of the bud from dark, light and receptor cells, formation of the taste pore and the presence and nature of contacts of intrage...

Ultraviolet radiation-B (UVBR) affects plants in many important ways, including reduced growth rate, reduction of primary productivity and changes in ultrastructure. The rice (Oryza sativa) is one of the most cultivated cereal in the world along with corn and wheat, representing over 50% of agricultural production. In this study, we examined O. sativa exposed to natural radiation denominated wh...
