in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...
expansive soils are considered a worldwide problem as they cause extensive damage tocivil engineering structures. an important characteristic of expansive soils is theirsusceptibility to volume change due to the phenomenon of wetting and drying. this paperpresets the effect of pore water quality on the swelling and shrinkage behavior of anexpansive soil during wetting and drying cycles. thirty ...
a research was carried out so as to determine the effect of iranian green tea (igt) powder in diet on blood metabolites and carcass traits of broiler chickens. therefore, considered four treatments consisting (basic diet + igt 5g/kg feed, basic diet + igt 10g/kg feed, basic diet + igt 15g/kg feed and one control diet without additive), and three replicates (15 chicks per repeat). this study las...
the effect of dietary terbutaline, a beta adrenergic agonist, on carcass characteristics and blood attributes in 288 japanese quails was studied from 21 through 49 days of age. dietary treatments included four levels of terbutaline [0 (t0), 1 (t1), 3 (t3), and 5 (t5) mg/kg of the diet]. quails were bled at the end of the trial for biochemical assays and the carcass characteristics were then mea...
Preeclampsia (PE) is an idiopathic multisystem disease affecting 5-7% of pregnant women. Placental oxidative stress is a characteristic feature of PE and occurs when the production of reactive oxygen species (ROS) within the placenta overwhelms the intrinsic anti-oxidant defenses. We hypothesize that excessive oxidative DNA damage at the fetal-maternal interface coupled with a defective DNA dam...
Glaucoma is a common ocular disorder that is a leading cause of blindness worldwide. It is characterized by the dysfunction and loss of retinal ganglion cells (RGCs). Although many studies have implicated various molecules in glaucoma, no mechanism has been shown to be responsible for the earliest detectable damage to RGCs and their axons in the optic nerve. Here, we show that the leukocyte tra...
Electronic retinal prostheses represent a potentially effective approach for restoring some degree of sight in blind patients with retinal degeneration. However, levels of safe electrical stimulation and the underlying mechanisms of cellular damage are largely unknown. We measured the threshold of cellular damage as a function of pulse duration, electrode size, and number of pulses to determine...
The prominence of reciprocal understanding in patient-doctor empathic engagement implies that patient perception of clinician's empathy has an important role in the assessment of the patient-clinician relationship. In response to a need for an assessment tool to measure patient's views of clinician empathy, we developed a brief (5-item) instrument, the Jefferson Scale of Patient Perceptions of ...
