Ultrastructural analysis of the growth cycles of Chlamydia trachomatis and Chlamydia psittaci showed that the chlamydial cell envelope became rigid and septated at the time of the reorganization from reticulate to elementary body. This process occurred in the immediacy of the inclusion membrane and in close proximity with the mitochondria or the endoplasmic reticulum of the host cell.
The effect of ethanolic extract of the whole plants of leptadenia reticulata has been studied in albino rats to explore it’s the anti-implantation and hormonal activities. A strong anti-implantation (inhibition 100%) and uterotropic activity was observed at the dose level of 300 mg /kg. No antiestrogenic activity could be detected.

گیاهان جنس لاله ( tulipa ) متعلق به تیره liliaceae در مناطق معتدله و نواحی نیمه گرمسیری جهان پراکنش دارند. این جنس در حدود 100 گونه دارد که 19 گونه آن از ایران گزارش شده است. با توجه به اینکه شناسایی و تعیین جایگاه و قرابت بین گونههای این جنس با استفاده از صفات ریخت شناسی با پیچیدگیهایی همراه است، لذا در این بررسی دانه گرده 15 گونه متعلق به 21 جمعیت از دو زیر جنس eriostemones و tulipa از منظر...
Acyclic directed graphs (ADGs) are increasingly being viewed as more appropriate for representing certain evolutionary relationships, particularly in biology, than rooted trees. In this paper, we develop a framework for the analysis of these graphs which we call hybrid phylogenies. We are particularly interested in the problem whereby one is given a set of phylogenetic trees and wishes to deter...
Rye (Secale cereale) is closely related to wheat (Triticum aestivum) and barley (Hordeum vulgare). Due to its large genome (~8 Gb) and its regional importance, genome analysis of rye has lagged behind other cereals. Here, we established a virtual linear gene order model (genome zipper) comprising 22,426 or 72% of the detected set of 31,008 rye genes. This was achieved by high-throughput transcr...
