dendrimer synthesis strategies now provide virtual control of macromolecular nanostructures as a function of size and surface/interior functionality. these strategies involve the covalent assembly of hierarchical components reactive monomers , branch cells or dendron’s around atomic or molecular cores according to divergent/convergent dendrite branching principles.combinon of two or more dendri...
the edge versions of reverse wiener indices were introduced by mahmiani et al. veryrecently. in this paper, we find their relation with ordinary (vertex) wiener index in somegraphs. also, we compute them for trees and tuc4c8(s) naotubes.
this study presents the influence of hydroxypropyl-β-cyclodextrin (hpbcd) on the aqueous solubility of acyl esters of cyproterone. first, a number of esters of cyproterone were synthesized. then the phase solubility analysis of the compounds in the presence of hpbcd was investigated in phosphate buffer solution at a ph of 7.4. to gain a better understanding of the complexation mechanism, the sy...
some fungal species were isolated from scab or scab-like symptoms on leaves of various plant hosts in iran. some of them isolated from apple and pear leaves were investigated in the present study. the isolates were identified based on the morphological and cultural characteristics. on the other hand, for molecular identification and phylogenetic analyses were carried out based on the sequence o...
pyrazine derivatives are important class of compounds with diverse biological and cytotoxic activities and clinical applications. in this study, b3 p 86 / 6 – 31 + + g * was used to compute and map the molecular surface electrostatic potentials of a group of substituted amides of pyrazine-2-carboxylic acids to identify common features related to their subsequent cytotoxicities. several statisti...
inter simple sequence repeat (issr) markers were used to assess the genetic diversity among 23 outcross and self pollinated populations of fennel collected from different geographical regions of iran and some european countries. the experiment was carried out to determine the effect of self-pollination on morphological traits and genetic diversity in the next generation. fifteen primers produce...
this work is conducted to obtain mechanical properties of microtubule. for this aim, interaction energy in alpha-beta, beta-alpha, alpha-alpha, and beta-beta dimers was calculated using the molecular dynamic simulation. force-distance diagrams for these dimers were obtained using the relation between potential energy and force. afterwards, instead of each tubulin, one sphere with 55 kda weight ...
objective(s): hepatitis c is a major cause of liver failure worldwide. current therapies applied for this disease are not fully effective and produce side effects in most cases. non-structural protein 3 helicase (ns3) of hcv is one of the key enzymes in viral replication and infection. therefore, this region is a promising target to design new drugs and therapies against hcv infection. the aim ...
methods this randomized, crossover study with parallel design was conducted in 45 patients who required maintenance hemodialysis due to end-stage renal failure. four patients with known bleeding disorders, receiving anticoagulant drugs and receiving drugs which could affect heparin activity were excluded. all patients were randomly assigned to receive either enoxaparin sodium (0.7 mg/kg) or sta...
background: toxocara is a common nematode of cats in different parts of iran. despite the close association of cats with human, no attempt has been done so far for molecular identification of this nematode in the country. therefore, current study was performed on identification of some isolates of toxocara from stray cats in shiraz, fars province, southern iran, based on morphological and molec...
