Abstract Implantation depends on bi-directional communication between the blastocyst and endometrium. Encoded in this is information maternal embryonic fitness, which turn can lead to activation of species-specific reproductive suppression mechanisms. For example, blastocysts over 130 mammals, although not humans, respond presence or absence specific endocrine endometrial cues by entering exiti...

ABSTRACT We have performed a frequency analysis of 10 092 ? Scuti-type stars detected in the fourth phase Optical Gravitational Lensing Experiment towards Galactic bulge, which is most numerous homogeneous sample Scuti observed so far. The main goal was to search for pulsating at least two radial modes simultaneously. found 3083 candidates such stars, largest set obtained date. Among them, 2655...
Abstract Introduction Testis microenvironment which is comprised of cells like Sertoli and peritubular releases paracrine factors could potentially modulate testicular functions. In our previous studies, we identified Leptin as a key factor in the microenvironment, released by goes to bind its receptor Leydig cells. Once this association happens it further induces expression desert hedgehog sig...
