androgenesis via anther culture or microspore culture is one of the current methods for producing haploid and double haploid plants in maize. to use of this method in maize breeding program it should be able to regenerate enough plantlets. anthers culture usually is carried out indirectly via callus induction and regeneration on at least two different media. in this study a responsive genotype,...

background: this study was performed to induce conversion of rh strain tachyzoites of toxoplasma gondii to bradyzoites by ph changing of the cul­ture medium. methods: hela cell monolayers were infected at a 1:1 tachyzoite to cell ratio. four hours after infection, the culture medium was removed and re­placed with culture medium and 5% fcs, adjusted to ph 8 with naoh. the culture was maintained ...

Development of MMRS (modified MRS Agar) culture medium; the absolute vegetarian culture medium containing plant seed powder in place of beef extract for the growth of probiotics. Vegetarian probiotic foods by definition must be free from all animal-derived ingredients. This research provides an alternative efficacious, cost effective vegetal culture medium. The culture medium developed in prese...

Metallothionein (MT) is a cysteine-rich protein that binds to heavy metals, and it is induced by them. The objective of this study to identify the MT protein induction/expression and localization in liver and kidney tissues (treated with 20 mg/L of CdCl2 for 72 hours) by immunohistochemical techniques and Western Blotting methods in the fresh water catfish, Clarias gariepinus. MT expression (MT...

pyricularia oryzae (tel. magnaporthegrisea) is currently used as a fungal model for plantmicrobeinteraction studies as well as an indicative model for anticancer drug discovery. thepresent study introduces the optimal condition in which p. oryzae grows and sporulates beston common culture media. we have considered three fungal culture media, i.e. pda, pca andwa, based on which p. oryzae sporula...

introduction: it is now generally accepted that vero cells provide beneficial effects on improving embryo quality in many animal species. the aim of this research was to determine the effect of vero cell co-culture on the development of vitrified 8-cell mouse embryos. material and methods: eight- cell mouse embryos were provided from superovulated female nmri mice and divided into treatment cas...

We quantify cytosolic and mitochondrial deoxyribonucleoside triphosphates (dNTPs) from four established cell lines using a recently described method for the separation of cytosolic and mitochondrial (mt) dNTPs from as little as 10 million cells in culture (Pontarin, G., Gallinaro, L., Ferraro, P., Reichard, P., and Bianchi, V. (2003) Proc. Natl. Acad. Sci. U. S. A. 100, 12159-12164). In cycling...

Overexpression of Smad ubiquitin regulatory factor 2 (Smurf2) in chondrocytes was reported to cause spontaneous osteoarthritis (OA) in mice. However, it is unclear whether Smurf2 is involved in bone and cartilage homeostasis and if it is required for OA pathogenesis. Here we characterized age-related changes in the bone and articular cartilage of Smurf2-deficient (MT) mice by microCT and histol...

The microtubule (MT)-stabilizing protein tau disengages from MTs and forms intracellular inclusions known as neurofibrillary tangles in Alzheimer's disease and related tauopathies. Reduced tau binding to MTs in tauopathies may contribute to neuronal dysfunction through decreased MT stabilization and disrupted axonal transport. Thus, the introduction of brain-penetrant MT-stabilizing compounds m...
