Cytoarchitecture of steroid dependent target tissues after testosterone administration compared to nandrolone decanoate in castrated rats in the aim of Hershberger bio test
The objective was the cytoarchitecture evaluation of known steroid dependent target tissues after administering of testosterone, compared to action of its more active ester, nortestosterone (nandrolone decanoate) in castrated rat males in the aim of Hershberger bio test. Study was performed on 30 castrated male Wistar rats, aged between 35 and 39 days, in peripubertal period, divided into five groups. Androgen doses administration begun at the rats’

Identifying almost-sorted permutations from TCP buffer dynamics
Associate to each sequence A of integers (intending to model packet IDs in a TCP/IP stream) a sequence of positive integers of the same length M(A). The i’th entry of M(A) is the size (at time i) of the smallest buffer needed to hold out-of-order packets, where space is accounted for unreceived packets as well. Call two sequences A, B equivalent (written A =_{FB} B) if M(A) = M(B). For a sequence of integers A define SUS(A) to be the shuffled-up-sequences

Introduction Human Wharton's jelly (WJ) has become a preferred source of mesenchymal stem cells (MSCs) whose clinical applications are limited by the use of adequate xeno-free (XF), in vitro manipulation conditions. Therefore, the objective of our study was to characterize WJ-derived MSCs (WJ-MSCs), isolated by different methods and cultured in a commercially available, MSC XF medium, not least of all by investigating their endothelial differentiation

Transformation (normalization) of slope gradient and surface curvatures, automated for statistical analyses from DEMs
Automated procedures are developed to alleviate long tails in frequency distributions of morphometric variables. They minimize the skewness of slope gradient frequency distributions, and modify the kurtosis of profile and plan curvature distributions towards that of the Gaussian (normal) model. Box-Cox (for slope) and arctangent (for curvature) transformations are tested on nine digital elevation models (DEMs) of varying origin and resolution, and
