Ovarian phagocyte subsets and their distinct tissue distribution patterns

The regulatory T cell family: distinct subsets and their interrelations.

Distinct volume subsets

Suppose that a and d are positive integers with a ≥ 2. Let ha,d(n) be the largest integer t such that any set of n points in Rd contains a subset of t points for which all the nonzero volumes of the (t a ) subsets of order a are distinct. Beginning with Erdős in 1957, the function h2,d(n) has been closely studied and is known to be at least a power of n. We improve the best known bound for h2,d...

vitrification affects the expression of matrix metalloproteinases and their tissue inhibitors of mouse ovarian tissue

background: one of the most major obstacles of ovarian tissue vitrification is suboptimal developmental competence of follicles. matrix metalloproteinases 2 (mmp-2) and 9 (mmp-9) and their tissue inhibitors timp-1 and timp-2 are involved in the remodeling of the extracellular matrix in the ovaries. objective: this study aimed to evaluate the expression of mmp-2, mmp-9, timp-1, and timp-2 genes ...

Ovarian tissue remodeling: role of matrix metalloproteinases and their inhibitors.

Follicular formation, growth or atresia, and ovulation as well as luteal formation and subsequent regression are dependent upon cyclical remodeling of the extracellular matrix (ECM). The proteinaceous and nonproteinaceous components of the ECM provide the tissue specific, extracellular architecture to which cells attach. Furthermore, the ECM modulates cellular activities through cellular surfac...

Distinct degrees and their distribution in complex networks

We investigate a variety of statistical properties associated with the number of distinct degrees that exist in a typical network for various classes of networks. For a single realization of a network with N nodes that is drawn from an ensemble in which the number of nodes of degree k has an algebraic tail, Nk ∼ N/kν for k 1, the number of distinct degrees grows as N1/ν . Such an algebraic grow...
