Purpose: To distinguish between benign and malignant mediastinal lymph nodes in patients with NSCLC by comparing 2D and semiautomated 3D measurements in FDG-PET-CT. Patients, material, methods: FDG-PET-CT was performed in 46 patients prior to therapy. 299 mediastinal lymph-nodes were evaluated independently by two radiologists, both manually and by semi-automatic segmentation software. Longest-...

For experiments on fission-fragment induced desorption the detection o f significant correlations between desorbed ions has been reported [1]. In this paper the method for the detection and quantitative description o f these correlations will be described. The statistics o f the desorption-process leads to equations for mass-line intensities o f ion spectra. Using a t ime-to-amplitude-converter...

abstract in order to genetic investigation of drought resistance indices, on 25 maize inbred lines, an experiment was conducted under three irrigation regimes; normal irrigation, limited vegetative irrigation and limited reproductive irrigation. in the limited vegetative irrigation, tol (stress tolerance) index had the highest phenotypic and genotypic coefficient of variation (83.83% and 68.04%...

conclusions mlva analysis showed that samples obtained from different sources could have similar genetic profile. as a result, administration of penicillin in patients with listeriosis (especially pregnant women) and antibiotic susceptibility test are recommended. the fast and accurate methods such as mlva for tracking of pollution sources of l. monocytogenes are recommended during outbreaks. r...

background and objectives: pneumocystis jiroveci is an important causative agent of pneumocystis pneumonia. during childhood, exposure to pneumocystis occurs and antibody was built in early childhood. the aim of this study was to describe the molecular epidemiology of p. jiroveci in children without any respiratory syndrome and survey the distribution of different mitochondrial large subunit, r...

this study aimed to examine the relationship between pigments and seed fall rate of iranian castor genotypes and genetic diversity, specifically 28 castor genotypes (27 native and 1 modified), a randomized complete block design with three replications was conducted in 2014 and 2015 at the research farm of islamic azad university in damghan, northern iran. during the growth period, the following...

cold stress is one of the most important environmental stresses for rice especially in temperate and high elevation areas. in present study, the effect of different temperatures, as the main plot, including 25 (control), 10 and 5°c on 12 rice cultivars (including champa yasouj, gerde, lenjan askari, kaamfirouz, kohsar, shafagh, domsiya mamassani, dular, gharib, hasan saraei, mosa tarom and 304)...

background: cryptosporidium parvum is a zoonotic pathogen transmissible from a variety of animals to humans and is a considerable public health concern. dairy cattle have been identified in numerous reports as a major source of environmen-tal contamination with this pathogen. the aim of study was to detect and isolate the cryptosporidium spp . from fecal samples of naturally infected pre-wean c...

Genotypic correlations and regressions can be estimated from multiallelic data sets either by weighting the allelic effects additively or by specifically weighting the genotypic interactions. Both methods can be extended to multiple loci, but they do not fully take into account the joint segregation patterns at the loci. These genotypic statistics have a great importance in sociobiological cont...

The aim of the study was to analyze the relationship between genotypic and phenotypic drug resistance profiles of human immunodeficiency virus type 1 (HIV-1) strains isolated from patients during double-analogue nucleoside therapy. A drug-resistant HIV strain was isolated from 20 out of 25 patients, with 16 (64%) subjects carrying a virus with multiple drug resistance mutations. The most freque...
