The discovery of the tetrodotoxin-resistant (TTX-R) Na(+) channel in nociceptive neurons has provided a special target for analgesic intervention. In a previous study we found that both morphine tolerance and persistent visceral inflammation resulted in visceral hyperalgesia. It has also been suggested that hyperexcitability of sensory neurons due to altered TTX-R Na(+) channel properties and e...

estimating fetal weight in utero, for better management of pregnancy and appropriate timing of delivery especially in high-risk pregnancies is necessary. our purpose to evaluate a simple method in estimating fetal weight in iranian pregnant patients and also to compare was with a previous western study. this study was carried out in arash hospital, tehran university of medical sciences in 1996-...

the rehabilitation of sandy desertified land in various dryland ecosystems by different management practices has a great potential to increase aggregate stability and improve soil quality. however, plants in general may have a different ability to sustain soil. the objective was to determine the effects of reclamation practices including haloxylon ammodendron and atriplex canescens plantation o...

      Euphrates poplar (Populus euphratica Oliv.) is a woody species that is naturally distributed in the desert areas of some parts of Asia and Africa. Because of its outstanding features, it is a model plant to study environmental stress tolerance. This research was conducted from 2014 to 2016 in order to study the relationship between performance indices and ion concentrations. The cuttings ...

abstract many uses of landscape and important roll of ground covers aspect turfgrasses caused extensive of this plant in the cities. this study focuses on shoot responses and tolerance of native and commercial turf grasses under drought stress in a factorial experiment based on unbalanced completely random design on the year 2006. the specious that we used in this experiment included (i) commer...

In the floriculture industry, the need for heat tolerant bedding plant cultivars is increasing because of the rising temperature around the world. A pot experiment was carried out to examine the impacts of four heat stress durations (0, 7, 14 and 21 days) on growth and ornamental traits to determine the relative heat tolerance of four cultivars of calendula (Calendula officinalis). Growth and d...

in order to select and release of bastan a new cultivar of foxtail millet, after preliminary selections in small millet germplasm a research was carried during 1997-2003 in karaj, golestan and dezful. during these years production potential of 10 foxtail millet genotypes was determined in a randomized complete block design for 3 years. the different characteristics include, leaf size, stem diam...

abstract in the present research the effect of different concentrations of cr3+ on growth and uptake of chromium by mycelium of agaricus bisporus was investigated. chromium playes an important role in improvment of insulin action in diabetic patients. the aim of this research was to investingate tolerance threshold of the fungus to cr3+ concentrations. mycelium of a. bisporus was cultured in so...

We discuss the problem of partitioning a set of points into two subsets with certain conditions on the diameters of the subsets and on their cardinalities. For example, we give an O(n log n) algorithm to find the smallest t such that the set can be split into two equal cardinality subsets each of which has diameter at most t. We also give an algorithm that takes two pairs of points (x, y) and (...

The transfinite diameter is a way of quantifying the size of compact sets in Euclidean space. This quantity is related to the Hausdorff dimension and the Lebesgue measure, but gives a slightly different perspective on the set than either of those do. In this paper, we introduce the transfinite diameter, and outline some attempts to calculate this quantity for three sets in R. For z1, z2, . . . ...
