Regulation of cell number in Drosopfiila

Nature, 1994
During animal development, different parts grow independently (such as the left and right hands) but they stop growing when they reach the correct size. In most insects, growth of the epidermis is so controlled that, at each moult, there is a precise and proportionate increase in cell number.

Estimation of the Number of Cells via the Number of Randomly Occupied Cells

Journal of Mathematical Sciences, 2016
Summary: We consider a scheme of series where the growth of the distribution support is asymptotically proportional to the growth of the sample size. It is assumed that the values of sample elements are inaccessible, whereas the number of different elements is known.

Uniqueness and the Cell Reynolds Number

SIAM Journal on Numerical Analysis, 1980
Using some results from the theory of M-functions, we show how uniqueness and multiplicity of solutions for three finite-difference approximations of the steady Burgers equation are related to the cell Reynolds number.

Mast Cell Numbers in Multiple Dermatofibromas

Dermatology, 1995
Multiple dermatofibromas (DFs) have been reported to develop in various disorders, especially in systemic lupus erythematosus (SLE).To investigate the role of mast cells in the formation of multiple DFs in association with autoimmune disorders, we quantified the number of mast cells.Three cases who developed multiple DFs with positive antinuclear ...

Optimal number of regulatory T cells

Journal of Theoretical Biology, 2010
The adaptive immune system of a vertebrate may attack its own body, causing autoimmune diseases. Regulatory T cells suppress the activity of the autoreactive effector T cells, but they also interrupt normal immune reactions against foreign antigens. In this paper, we discuss the optimal number of regulatory T cells that should be produced.

The economic cell number

The International Journal of Advanced Manufacturing Technology, 2008
The economic benefits brought by the cellular manufacturing have been reported. Cell formation is one of the most important problems in the design of a cellular manufacturing. In cell formation problems, the number of cells is a critical factor. However, it is impossible to know the number of cells before solving the cell formation problem.

Regulation of granule cell number by a predetermined number of Purkinje cells in development

Developmental Brain Research, 1989
Development dysgenesis of Purkinje cells or granule cells was analyzed for the reciprocal effect of reduced number of each cell type on the other. A single pre- or postnatal injection of methylazoxymethanol acetate (MAM) in the rat reduces either the number of Purkinje cells or the number of granule cells when administered at the time of their ...

Fuzzy n-cell numbers and the differential of fuzzy n-cell number value mappings

Fuzzy Sets and Systems, 2002
Based on the Cartesian product of \(n\) closed intervals, the authors have introduced so-called fuzzy \(n\)-cell numbers and their calculus (this is done by means of the standard alpha-cuts approach). Some other properties (e.g., Hausdorff metric) of these fuzzy numbers are investigated.

In Vivo Stem Cell Transplantation Using Reduced Cell Numbers

2014
Dental pulp stem cell (DPSC) characterization is essential for regeneration of a dentin/pulp like complex in vivo. This is especially important for identifying the potential of DPSCs to function as stem cells. Previously reported DPSC transplantation methods have used with huge numbers of cells, along with hydroxyapatite/tricalcium phosphate (HA/TCP ...

Efficiency vs. number of cells in cell formation

2018 Third International Conference on Electrical and Biomedical Engineering, Clean Energy and Green Computing (EBECEGC), 2018
The effects of some of the physical, technological, or organizational constraints will force the system designer to specify the number of cells in advance. Different layouts and alternative optimal solutions will give the designer more flexibility to avoid some of these constraints. In this paper a sensitive analysis of the impact of number of cells on
