primary angiitis of the central nervous system (pacns) is an idiopathic disorder (vasculitis) restricted to the central nervous system (cns). it often presents with focal neurological deficits suggesting stroke or a combination of confusion and headache. we herein report three cases with various combinations of fever, partial seizure, encephalopathy, paresis, headache and ataxia. one of them wa...

cleft hand deformity is a rare congenital anomaly of the hand with an incidence rate about 1/90,000. it has two clinical types typical and atypical. in this paper we are representing ten cases of this anomaly admitted during seven years from 1992 in emam khomeini hospital. some of the patients especially those with typical cleft hand deformity achieved good functional results after surgical cor...

purpose: to determine the effect of intravitreal triamcinolone (ivt) injection on visual acuity in patients with ischemic central retinal occlusion (crvo). methods: this randomized clinical trial was performed on patients with ischemic crvo referred to the retina clinic at feiz hospital in 2007-2008. inclusion criteria were: duration of crvo less than one month, normal iop, no sign of diabetic ...

BACKGROUND AND AIMS Shoot-borne roots contribute to most of the nutrient uptake throughout the life cycle of maize (Zea mays). Compared with numerous studies with embryonic roots, detailed information on the phenotypic plasticity of shoot-borne roots in response to a heterogeneous nitrogen supply is scarce. The present study therefore provides a comprehensive profile of fine-scale plastic respo...

Thalamic pain syndrome, a type of central post-stroke pain (CPSP), may develops after a hemorrhagic or ischemic stroke and results in impairment of the thalamus. There is limited experience about gabapentin in treatment of central pains like CPSP.In a prospective observational study, the intensity of pain was recorded using the Numeric Rating Scale (NRS) at the entrance to the study. Patients e...

Genotypic variability in vulnerability of leaf xylem to water-stress-induced cavitation was determined in four sugarcane (Saccharum sp.) clones using detached leaf segments in a hydraulic conductivity apparatus. Vulnerability curves were constructed by plotting the percentage of maximum conductivity versus leaf water potential (psi(I)) and fitting curves using a Weibull function. The psi(I) at ...

First-instar nymphs of periodical cicadas (Homoptera: Cicadidae: Magicicada) were introduced into a 500-cm plot in a relatively pure stand of loblolly pines and into an 1800-cm plot on a mowed grassy lawn to determine whether they could feed on pine and grass roots, respectively. Nymphs and their associated roots were excavated within a 2-year period after introduction. Serial root sections fro...
