Genetic imprinting during impaired spermatogenesis

Differential histone modifications mark mouse imprinting control regions during spermatogenesis.

Only some imprinting control regions (ICRs) acquire their DNA methylation in the male germ line. These imprints are protected against the global demethylation of the sperm genome following fertilisation, and are maintained throughout development. We find that in somatic cells and tissues, DNA methylation at these ICRs is associated with histone H4-lysine-20 and H3-lysine-9 trimethylation. The u...

MUC1 in normal and impaired spermatogenesis.

The MUC1 mucin [also known as episialin, epithelial membrane antigen (EMA) or polymorphic epithelial mucin (PEM)] is a component of the mucosal glycocalyx, contributing to anti-adhesive and protective cell functions. MUC1 has been shown in a variety of epithelial cell types in the reproductive tracts of males and females, but this is the first report of its expression in human testis and non-ep...

3D Imprinting of Environment for Visually Impaired

The aim of this article is focused on the design of an obstacle detection system for assisting visually impaired people. A simple Time of Flight camera captures real time images present in the environment of the subject. These images are analyzed using OpenCV and MATLAB for depth and position of objects. The disparity map created is segmented into depth categories. A matrix of this data corresp...
