In this paper we aim to describe the propagation of a ”failure event” through a metabolic network (i.e. no formation of a set of metabolites) and, by means of a Markov chain, to be able to compute the long–run failure probability of each metabolite following a transient random failure event occurring somewhere in the network. Moreover, we will introduce and motivate the definition of a ”toleran...

Plants of six wheat varieties (Damani, Hashim-8, Gomal-8, DN-73, Zam-04, and Dera-98) were grown under three water regimes i.e. 100% Field Capacity (FC), 35% FC and 25% FC. Results of this experiment showed highly significant difference among wheat varieties in all the studied traits and water stress conditions decreased them significantly. The superior variety Hashim-8 which indicated higher r...

OBJECTIVE The study objective was to assess the relationship between β-cell function and HbA(1c). RESEARCH DESIGN AND METHODS A total of 522 Mexican American subjects participated in this study. Each subject received a 75-g oral glucose tolerance test (OGTT) after a 10- to 12-h overnight fast. Insulin sensitivity was assessed with the Matsuda index. Insulin secretory rate was quantitated from...

This study examines the loss of peripherally induced B cell immune tolerance in Rheumatoid arthritis (RA) and establishes a novel signaling-based measure of activation in a subset of autoreactive B cells--the Induced tolerance status index (ITSI). Naturally occurring naïve autoreactive B cells can escape the "classical" tolerogenic mechanisms of clonal deletion and receptor editing, but remain ...

In order to identify drought tolerant chickpea genotypes, an experiment was conducted in the west of Iran, during 2007-2009 cropping seasons. Several selection indices were used to illustrate genotypic differences in response to drought stress. The results of combined analysis of variance showed that year, genotype, stress conditions and their interaction effects were highly significant. Correl...

Due to industrialization, urbanization and increasing number of vehicles air pollution has turn out be serious problem today. Now a days particulate matter shows the undesirable effects on plants, animals human beings also. Tree plantation programme is best ways control pollution. Most plants filter by their aerial elements. Vegetation naturally cleanses atmosphere absorbing gases some matters ...

drought is the most significant constraint for crop production in arid and semi-arid regions. in order to assess drought tolerance in fifteen rapeseed (brassica napus) cultivars using yield-based drought tolerance indices, two experiments were conducted at the research station of college of agriculture, shiraz university, shiraz, iran during 2009-2010 growing season. the cultivars were arranged...

drought is a major limiting factor for agricultural production in most parts of the world and landraces areimportant genetic resources for crop improvement in dry areas. during the 2007-2008 cropping season, 23 chickpea (cicer arietinum l.) genotypes consisting of 21 kabuli chickpea landraces provided by the national plant gene bank of iran and two known commercial varieties (hashem and arman) ...

changes in chlorophyll florescence is one of the physiological responses of plants to waterlogging stress. due to easily measured in field and its inexpensive and non-destructive characteristics, it is one of the best ways to assess different genotypes tolerance to stresses. in this experiment, trends of chlorophyll fluorescence index (fv/fm) of ‘satsuma’ mandarin (citrus unshiu) on seven roots...

OBJECTIVE To determine the prevalence of metabolic syndrome and insulin resistance in Thai women with polycystic ovary syndrome (PCOS). MATERIAL AND METHOD Oral glucose tolerance tests were performed in 70 PCOS women. Blood was taken for the measurement of fasting insulin, 2-hr postprandial insulin, lipid profiles, testosterone and sex hormone binding globulin RESULTS The prevalence of meta...
