aligned and random nanocomposite nanofibrous scaffolds were electrospun from polycaprolactone (pcl), poly (vinyl alcohol) (pva) and hydroxyapatite nanoparticles (nha). the morphology and mechanical characteristics of the nanofibers were evaluated using scanning electron microscopy and tensile testing, respectively. scanning electron microscopy revealed fibers with an average diameter of 123 ± 3...

introduction: parasitic diseases could be one of the common problems of human society in any time in every place. the animals can passed this infection to human as zoonotic disease. cats are one of the most important animals that living and eating long with human in society. therefore feline parasitic zoonosis is threatened human health and cause death and serious disease. for the reason, the p...

results implementation of modern techniques of immune monitoring, allograft function, awareness about the specific infectious and non-infectious disease in each region improves the quality of renal transplantation. conclusions we need to combine the advance scientific vision with local vigilance to achieve the best outcome in renal allograft recipients evidence acquisitions in this process we s...

background: cardiac involvement in systemic sclerosis (ssc) is more prevalent than previously thought. in this study, the frequency and severity of cardiovascular involvement were assessed in ssc patients referred to firouzgar hospital. methods: fifty-eight patients with ssc, selected from the data bank of ssc patients, were reviewed for the frequency and severity of 8 organ involvements in thi...

abstract this experiment was conducted for optimizing a suitable medium for callus induction, regeneration and rooting of anthurium. leaf and petiol explants of antadra and casino varieties were used for callus production. ms medium was supplied with growth regulators (naa, ba, kin and iba). a complete randomized design with 3 replication was used in this expriment. result indicates that variet...

objective(s) bone marrow is the traditional source of human multipotent mesenchymal stem cells (mscs), but adipose tissue appears to be an alternative and more readily available source. in this study, rat adipose-derived stem cells (adscs) were induced to differentiate into schwann-like cells and compared with rat bone marrow stem cells (bmscs) for their schwann-like cells differentiation poten...

objective (s): the scarcity of articular cartilage defect to repair due to absence of blood vessels and tissue engineering is one of the promising approaches for cartilage regeneration. the objective of this study was to prepare an extracellular matrix derived decellularized bovine articular cartilage scaffold and investigate its interactions with seeded rat bone marrow mesenchymal stem cells (...

tenecteplase is a variant of tissue plasminogen activator (t-pa) which has better pharmacokinetic properties and more selective thrombolytic activity. in the present study, we describe a rapid method to introduce three sets of mutation into defined positions in t-pa cdna by a site-directed mutagenesis based on a megaprimer pcr approach to produce tenecteplase coding sequence where amino acids a...

background:   to introduce our experience of using the free neurovascular flap from great and second toe. methods:   thirteen patients (fifteen fingers) sought surgical treatment for soft tissue defects of the hand at our medical institutin between march 2006 and september 2009. in two patients, fibular side skin-nail flaps of great toe were applied to cover the dorsal defect of distal thumb. i...

conclusions large-scale studies on the healthy black african population could assess the relationship between diastolic dyssynchrony and changes in myocardial performance related to racial differences. results the frequency of some dyssynchrony markers was similar to that of other studies. the difference between maximal time-to-peak systolic velocity and minimal time-to-peak systolic velocity w...
