OBJECTIVE To assess the effects of a new neuroprosthesis (NESS L300) designed to ameliorate foot drop on gait symmetry and rhythmicity during walking. DESIGN Twenty-four patients (mean age: 54.0 +/- 13.5 yrs) with chronic hemiparesis (5.8 +/- 5.2 yrs) whose walking was impaired by foot drop. Subjects walked for 6 mins while wearing force-sensitive insoles, once with and once without the neuro...

We present new functional equations for the species of plane and of planar in the sense of Harary and Palmer, 1973 2-trees and some associated pointed species. We then deduce the explicit molecular expansion of these species, i.e.a classiication of their structures according to their stabilizers. Therein result explicit formulas in terms of Catalan numbers for their associated generating series...

the present study carried out to identify neo tectonic activity of the gorgan river basin in golestan province, in north of eastern alborz range is investigated by four geomorphic indices including the stream– gradient index (sl), drainage basin asymmetry (af), reveres symmetry of topography (t) and mountain front sinuosity (smf). result from the analysis is accumulated and expressed as an in...

PURPOSE To evaluate whether baseline visual field data and asymmetries between eyes predict the onset of primary open-angle glaucoma (POAG) in Ocular Hypertension Treatment Study (OHTS) participants. METHODS A new index, mean prognosis (MP), was designed for optimal combination of visual field thresholds, to discriminate between eyes that developed POAG from eyes that did not. Baseline intrao...

In this research the metaphase chromosome number and karyotype of Astragalus stenosemioides species growing naturally in Turkey are studied. The study revealed that A. is 2n = 16. basic determined as x 8. formula 8m. total length somatic chromosomes ranges between 1.96 - 3.38 μm. haploid 21.36 addition, asymmetry was evaluated by different methods; Stebbins classification, TF%, AsK%, Syi Rec, A...

The cytological features including chromosome numbers and detailed measurements of 46 populations ten Achillea species ( A. aleppica, bibersteinii, eriophora, filipendula, millefolium, nobilis, pachycephala, tenuifolia, vermicularis, wilhelmsii ) were reported from Iran. Sample plants seeds collected diff erent geographical regions Total length, long/ short arm ratio, centromere index, total fo...

The hopelessness theory of depression proposes that individuals with a depressogenic cognitive style are more likely to become hopeless and experience depression following negative life events. Although the neurophysiological underpinnings of cognitive style remain speculative, research indicates that decreased relative left frontal brain electrical activity holds promise as a traitlike marker ...

With the purpose of addressing the pattern of karyotype evolution in Caesalpinia species, chromosome morphology was characterized in five species from Brazil, and karyotypic asymmetry was analyzed in 14 species from South America. All accessions had the chromosome number 2n = 24, which was first described here for Caesalpinia laxiflora Tul. and Cenostigma macrophyllum Tul. The karyotype formula...

OBJECTIVES To develop a new analysis method for the quantitative assessment of vibration of the vocal folds, using conventional videostroboscopic image data. METHODS We used prerecorded videostroboscopic images to evaluate quantitatively the vibration of the vocal folds. Successive images were converted as digital images by means of an image-grabbing board, processed for analysis, and reconst...

DNA replication was recently shown to induce the formation of compositional skews in the genomes of the yeasts Saccharomyces cerevisiae and Kluyveromyces lactis. In this work, I have characterized further GC and TA skew variations in the vicinity of S. cerevisiae replication origins and termination sites, and defined asymmetry indices for origin analysis and prediction. The presence of skew jum...
