nano-films consisting of an alternating sequence of positively and negatively charged polyelectrolyteshave been prepared by means of the electrostatic layer-by-layer sequential assembly technique on mildsteels. the mild steels were pretreated electrochemically to modify the mild steel surface. the modificationof the mild steel surface resulted in increasing the adhesion of the obtained nano-fil...

abstract nowadays, bypassing agents such as recombinant activated factor vii (rfviia) and activated prothrombin complex concentrates (apcc) are used to treat bleeding episodes in the hemophilia patients with inhibitors. aryoseven® is an iranian biogeneric rfviia with homogeneity of efficacy and the nature to novoseven in a comparative trial. the current clinical trial aimed to evaluate the cost...

histone deacetylase inhibitors have gained a great deal of attention recently for the treatment of cancers and inflammatory diseases. so design of new inhibitors is of great importance in pharmaceutical industries and labs. creating pharmacophor models in order to design new molecules or search a library for finding lead compounds is of great interest. this approach reduces the overall cost ass...

a new series of alkylthio imidazole analogues of captopril, an ace inhibitor used in the treatment of hypertension, was designed and synthesized in order to obtain agents more active than captopril with less side effects. all the compounds thus prepared were purified and characterized by ir, nmr and mass analytical instruments.

objective: alpha-synuclein is a major component of protein plaques in synucleinopathies, particularly parkinson’s disease. the purpose of this study is to assess the inhibitory effects of cuminaldehyde on the fibrillation of alpha-synuclein. methods: alpha-synuclein was expressed in escherichia coli and subsequently purified. for the process of fibrillation, purified protein was incubated at 3...

factors such as oxidative stress and reduced acetylcholine level have been implicated in alzheimer’s disease (ad) pathology and recently there has been a trend towards natural product research to find potential sources of antioxidants and acetylcholinesterase inhibitors in the plants kingdom. centaurea is a genus with about 500 species world wild, many of them have shown to possess biologic act...

inhibitor development is a lifelong challenge for patients with bleeding disorders who received replacement therapy. most commonly, inhibitor formation was observed in hemophilia a patients but patients with rare bleeding disorders (rbd) especially patients with deficiency of factor xiii (fxiii) and factor v (fv) can develop an inhibitor against exogenous factors. several factors considered as ...

background: leukemia inhibitor factor (lif) is a very important pleiotropic cytokine which belongs to interleukin-6 (il-6) family. lif exerts multiple effects on different types of cells and tissues with numerous regulatory effects in vivo and in vitro. it is a lymphoid factor, which performs a number of activities including cholinergic neuron differentia­tion, control of stem cell pluripotency...

patients with coagulation factor(s) deficiency who use coagulation therapy are susceptible to forming inhibitors against coagulation factor(s). in this survey we detected factor v and viii inhibitor in ten patients with combined deficiency of factors v and viii from north east of iran (khorassan province). it was revealed in our survey that eight patients had both factor v and factor viii inhib...

background: factor viii inhibitor is one of the most problems in the treatment of hemophilia. patients with hemophilia who have inhibitors are capable of severe hemorrhage and treatments of these patients are more expensive and more difficult than those patients without inhibitor. the aim of present study was to determine the prevalence of inhibitor and to assess the necessity of screening of t...
