Knowledge of the relationships between biotic components of rangeland ecosystem i.e. herbivores and plants is important for range managers. In order to study herbivorse grazing intensity on plant species diversity, an experiment was conductef using fuor grazing treatments in darrehshar rangelands, Ilam province in 2015. Plant species data were taken based on a randomized-systematic sampling met...

Background: Hyper-androgenemia is one of the main clinical features of polycystic ovarian syndrome (PCOS). Letrozol is an aromatase inhibitor drug, which is co-administered with gonadotropins in most cases of PCOS, to improve ovulation. Aromatase has a critical role in catalyzing the conversion of androgens to estrogens and is responsible for keeping the homeostatic balance between them. Hence ...

In the title compound, C(20)H(24)N(4) (2+)·2PF(6) (-), the ethene and 3-allyl-imidazolium moieties of the cation are disordered over two positions with refined site occupancies of 0.664 (19):0.336 (19) and 0.784 (7):0.216 (7), respectively, whereas four F atoms of one hexa-fluoridophosphate anion and all atoms in the other hexa-fluoridophosphate anion are disordered over two positions with refi...

Synaptotagmins 1 and 7 are candidate Ca(2+) sensors for exocytosis localized to synaptic vesicles and plasma membranes, respectively. We now show that the N-terminal intraluminal sequence of synaptotagmin 1, when transplanted onto synaptotagmin 7, redirects synaptotagmin 7 from the plasma membrane to secretory vesicles. Conversely, mutation of the N-terminal N-glycosylation site of synaptotagmi...

background different methods for dressing of donor site of skin graft in burn patients have similarly pain, limitation of mobility of donor site and local complications such as infection and scar. amniotic membrane has used for improvement of healing in some wounds. accordingly in this study amnion was used as biologic dressing for donor site of skin graft to evaluate it’s efficacy in improveme...

The sesquiterpene cyclase aristolochene synthase from Penicillium roquefortii (PR-AS) has evolved to catalyse with high specificity (92%) the conversion of farnesyl diphosphate (FDP) to the bicyclic hydrocarbon (+)-aristolochene, the natural precursor of several fungal toxins. Here we report that PR-AS converts the unnatural FDP isomer 7-methylene farnesyl diphosphate to (+)-aristolochene via t...
