Background: Sustainable and commercial production of secondary metabolites is a critical issue when dealing with its clinical application. Efforts are still being made to look for biotic or abiotic elicitors with more efficient and universal effects on the improvement of secondary metabolites. Objective: In order to evaluate the suitability of different biotic elicitors on P. harmala L. cell...

Background The aim of this study was to establish a cell-free sequential culture system that can support high levels of in vitro embryo development and blastocyst formation from bovine zygotes. To this end, this investigation was carried out to evaluate the effects of glucose, serum and EDTA on bovine zygote in vitro development. MaterialsAndMethods Bovine presumptive zygotes were derived from ...

résumé : la "langue" est beaucoup plus quun simple outil de communication et elle représente la réalité sociale de celui qui lutilise. la langue façonne la perception des gens et leur vision du monde en portant la culture. dans l’enseignement des langues, il apparaît ainsi important de privilégier les contacts entre les différentes cultures et le développement dune compétence interculturelle....

Objective Genetic and morphologic similarities between mouse embryonic stem cell (ESCs) and Primordial Germ Cell (PGCs) make it difficult to distinguish the two cell types in in vitro differentiation. Using the expression of specific markers of germ cells that are not expressed or expressed at low levels in ESCs, can help recognizing in vitro differentiated cells MaterialsAndMethods In this stu...

Breast cancer tissues include carcinoma cells and stromal cells, intra-tumoral stroma that consists of different types cells. For this point, cell-cell interaction communication have a potential role in progression. Mono-cell culture is used for treatment approaches. However, can not be evaluated on mono-culture So, co-culture models provide low-cost screening to determine cell proliferation dr...

Objective(s): Irinotecan is a potent anti-cancer drug from camptothecin group which inhibits topoisomerase I. Recently, biodegradable and biocompatible polymers such as poly lactide-co-glycolides (PLGA) have been considered for the preparation of nanoparticles (NPs). Materials and Methods: In this study, irinotecan loaded PLGA NPs were fabricated by an emulsification/solvent diffusion method to...

This study was designed to examine the effects of retinoic acid adding to cumulus and/or fibroblast cellsmonolayer on the development of mouse early embryos. One-cell mouse embryos were obtained from NMRImice after superovulation by an intraperitoneal injection of 5 IU equine chorionic gonadotrophin (eCG)followed 48 hrs later by 5 IU human chorionic gonadotrophin (hCG). Mouse embryonic fibrobla...

apoptosis, or active cell death, is a specific mode of cell death, which is characterized by morphological changes such as chromatin condensation, fragmentation of the nucleus, cytoplasmic retraction and appearance of apoptotic bodies' containing apparently intact organelles. apoptosis occurs in physiological conditions as a regulatory mechanism of tissue growth, where cell proliferation is bal...

Background: The induction of bystander effect via ionizing radiation has been well proven. However, few studies have investigated the bystander effect following non-ionizing radiation, such as ultrasound waves. Here, the bystander effect after different sonication times on human melanoma cell line (A375), is evaluated by assessing cell viability and apoptosis. Materials and Methods: The cells w...
