Cell therapy has been linked to an unexplained return of ovarian function and fertility in some cancer survivors. Studies modeling this in mice have shown that cells transplantation generates donor-derived oocytes in chemotherapy-treated recipients. This study was conducted to further clarify the impact of cell transplantation from different sources on female reproductive function after chemoth...

In this paper, the modeling and control of reluctance-force-based magnetic suspension in cylindrical rotor, ring-shape air gap, bearingless motors are presented. The full suspension system dynamics, including both the destabilizing force due to the motor field and the active magnetic suspension control forces, are modeled, and a transfer function of the bearingless motor suspension plant is der...

introduction: the aim of this study was to determine a proper cell line for adherance of helicobacter pylori and a suitable method for attachment of this bacteria to cell lines in vitro. material and methods: a total of 22 h.pylori strains,isolated from the antral biopsies of 49 patients with dyspepsia,gastritis,gastric ulcer,duodenal ulcer, etc., were evaluated by elisa(upr)to determine the di...

introduction: introduction: leucocytes accounted for 26-36% of the stromal cells in decidua of the first trimester of gestation in which 75% of them is related to endometrial granulated lymphocytes (egl) with an unusual natural killer (nk) cell-like phenotype. different roles are proposed for egl, but fundamental role of these cells in control for normrly underestood. material and methods: in t...

Background : It is difficult to prospectively identify and maintain putative tumor-initiating cells (TICs). Spheres that formed in serum-free media contained more TICs while spheres formed in serum-containing media were not used in tumor-initiating. Methods : Soft-agar was used to isolate colonies. A continuous, static suspension culture using serum-containing media was modified from liquid ove...

neospora caninum is a coccidian protozoan parasite which is a major cause of bovine abortions and neonatal mortality in cattle, sheep, goat and horse. occasionally, cultured cells are used for isolation and multiplication of the agent in vitro with several purposes. in this study the tachyzoite yields of n. caninum were compared in various cell cultures as the host cell lines. among the cell cu...

The effect of industrial sludge toxicity on the cell growth of a green paramecium, Paramecium bursaria was examined. P. bursaria cells were cultured in a lettuce medium supplemented with various concentrations of sludge suspension at 23 °C under LD (ligh and dark cycle) condition. Results suggested that P. bursaria proliferates normally even at 1.5% sludge suspension. However, 1.5x10 % sludge s...

Zinc and iron nano-oxides (100 ppb) were promoted the hypericin and hyperforin production in Hypericum perforatum cell suspension culture. High performance liquid chromatography method was used for detectection and identification of hypericin and hyperforin in H. perfuratum cell suspension cultures elicited with different concentrations of zinc and iron nano-oxide (0, 50, 100 and 150 ppb) after...

In this paper, the effect of pH on in vitro cell growth and naphthoquinone pigment production in cell suspension cultures of Arnebia euchroma (Royle) Johnston was evaluated under a two-stage culture system. Friable callus derived from leaves of in vitro established shoots was maintained on MS medium supplemented with BAP (10 μM) and IBA (5 μM) and the same medium was used for raising cell suspe...

background and aims: understanding β-cell function at the molecular level will likely facilitate the development of β-cells manufacture techniques. the aim of the present study was to investigate the pancreatic and duodenal homeobox 1 (pdx-1) gene expression into dtz-stained cellular clusters originating from emberyonal carcinoma cells. methods: this implemental -fundamental study was accomplis...
