Development is a leading primary research journal covering the field of developmental biology. The sperm motility enhancers caffeine and theophylline improved cleavage and embryo development rates, synthetic oviducal fluid fertilisation medium outperformed M199 fertilisation medium and shortening the oocyte-sperm coincubation time (from 18 to 8 h) resulted in similar overall embryo performance rates.
The aim of the present study was to elucidate the regulatory role of cell proliferation and apoptosis in this dynamic testicular development. The Office of Strategic Planning and Development Effectiveness (SPD) engages in the evaluation of projects at different levels according to the demands from project teams and the strategic relevance of a particular operation. To measure the effectiveness of Bank’s development interventions each project team prepares the Loan Results Report (LRR) 18 months after the first disbursement is made. These results show that FSH protects against Sertoli cell tumour growth during discrete windows of testicular development.
While other theories of career development stress that vocational choices are determined by persons and their environments, these same theories also fail to take into account the behavior of the individual in influencing particular situations which can in turn then affect their thoughts and subsequent behaviors.
Results demonstrate the strong regulatory effect of the uterus on conceptus development and the importance of synchrony for optimal pregnancy rates. The reproductive tract secretes molecules collectively known as embryokines that regulate embryonic growth and development. A unique approach to managing coyote (Canis latrans) depredation is the development of a one-time deliverable chemical sterilant.
Roe (1956) herself felt more attention should be paid to the role of occupation in the life of an individual and that occupations should be open to all, particularly women and minorities, since appropriate work can be satisfying not only to society but to the individual.
