In order to investigate tooth development, several cell lines of the dental epithelium and ectomesenchyme have been established. However, no attempt has been reported to regenerate teeth with cell lines. Here, we have established several clonal cell lines of the dental epithelium from a p53-deficient fetal mouse. They expressed specific markers of the dental epithelium such as ameloblastin and ...

Differential fields of germs of continuous real valued functions of one real variable (Hardy fields) have the property that all elements have limits in the extended real numbers and thus have a canonical valuation. For differential fields of holomorphic germs this is not generally the case. We provide a criterion for differential fields of holomorphic germs for its elements to have uniform limi...

This paper introduces a watershed-based stochastic segmentation methodology. The approach is based on using M realizations of N random markers to build a probability density function (pdf) of contours which is then segmented by volumic watershed for de ning the R most signi cant regions. It over-performs the standard watershed algorithms when the aim is to segment complex images into a few regi...

Tooth morphogenesis is carried out by a series of reciprocal interactions between the epithelium and mesenchyme in embryonic germs. Previously clonal dental epithelial cell (epithelium of molar tooth germ (emtg)) lines were established from an embryonic germ. They were odontogenic when combined with a dental mesenchymal tissue, although the odontogenesis was quantitatively imperfect. To improve...

Twice in the history of this Society have our presidents directed the attention of its members to the influence of germs in the production of disease. Our first president, Dr. Brittan, in the year 1874, propounded, illustrated, and illuminated this question: first, from what we know of diseased blood, and of the " blood diseases;" secondly, from what we know of the blood-germs, and bioplastic m...

manure and putreseible garbage are some of the main sources of pathogenic germs in countryside’s. on the other hand, demand for fertilizer and energy increases in rural areas every day. to study potential of cow manure for these requirements a 16,5m3 pilot plant was designed and constructed as fermentation tank near animal husbandry of karaj agriculture faculty. some 260kg cow manure and water ...

Background: food contamination can be caused by various factors, including personal hygiene, handler knowledge, sanitation, and the cleanliness of cutlery. A microbiological examination that done is a swab cooking utensils cutlery, germ count examination. Germ found in cutlery will pose health risk to consumers.Objectives: purpose this study was determine number bacterial colonies on between so...

We consider germs of conformal mappings tangent to the identity at the origin in C. We construct a germ of a homeomorphism which is a C∞ diffeomorphism except at the origin conjugating these holomorphic germs with the time-one map of the vector field V (z) = zm ∂ ∂z . We then show that, in the case m = 2, for a germ of a homeomorphism which is real-analytic in a punctured neighborhood of the or...
