this study was designed to investigate the structural characteristics of beech forests in the middle stage of ecological succession. in order to this purpose undisturbed beech stands in kheyroud forest had chosen and three one hectare sampling plot laid out. all of tree species measured with full callipering method and diameter and height of trees were recorded. natural regeneration within one ...

We have isolated two etoposide (VP16)-resistant cell lines, KB/VP-1 and KB/VP-2, from human cancer KB cells after stepwise exposure to increasing doses of VP16. KB/VP-1 and KB/VP-2 showed 30and 50fold higher resistance to VP16 and also 20and 30-fold higher resistance to teniposide than the parent cell line. Furthermore, both resistant cell lines showed more than 2-fold cross-resistance to Adria...

Plasma concentrations of gastrin, somatostatin, neurotensin, and enteroglucagon were measured by radioimmunoassay in normal 30and 45-day-old neonates and age-matched infants with confirmed idiopathic hypertrophic pyloric stenosis. Plasma gastrin and somatostatin concentrations were similar in both groups, whereas neurotensin and enteroglucagon were significantly lower in the pyloric stenosis gr...

A time-dependent close-coupling method is combined with a time-independent distorted-wave method to calculate the electron ionization cross section for hydrogen. A second-order differencing of the time propagator for the close-coupled equations is found to be very efficient. Low partial-wave close-coupling results are added to high partial-wave distorted-wave results to yield total ionization c...

Background and Purpose—Sex may predict level of care and successive outcome among patients with stroke. We examined fulfillment of quality of care criteria according to sex and possible impact of any sex-related differences on short-term mortality in a population-based nationwide follow-up study in Denmark. Methods—We identified 29 549 patients admitted with stroke between January 2003 and Octo...

Bardet Biedl syndrome (BBS) is a rare autosomal recessive disease, characterized by clinical and genetic heterogeneity. Many genes are involved. BBS seems to be different from Lawrence Moon BBS, although they share some clinical symptoms. The main clinical signs are obesity, pigmentary retinopathy, kidney malformations, and hypogenitalism. Our aim is to report a case with typical retinis pigmen...

This paper presents an approach to determine the optimal PMU locations in order to render the complete observability to given power system using BPSO. Quadratic programming approach is used in BPSO, and results so obtained are compared with GAMS-MIP solver. A Method for Pseudo observability is also proposed for depth-one and depth-two with and without Zero injection measurements for IEEE-7, IEE...

Background. Limited data on the incidence and clinical characteristics of IRIS in neutropenic patients with IPA were available. Methods. During 6-year period, adult patients with neutropenia who met probable or proven IPA by the EORTC criteria were retrospectively enrolled. IRIS was defined as new appearance or worsening of radiologic pulmonary findings temporally related to neutrophil recovery...
