Variability in penetration, development, and reproduction of two resistance-breaking field pathotypes (pt.) of Meloidogyne arenaria, M. incognita, and a population of mixed Meloidogyne spp. virulent to grape hosts were compared on two resistant Vitis rootstocks 'Freedom' and 'Harmony' in separate tests. 'Cabernet Sauvignon' was included as a susceptible host to all four nematode populations. Se...

Attachment of relatively low numbers of endospores from two isolates of Pasteuria spp. to several species of nematodes was consistently achieved in 2-5 minutes with a centrifugation technique. The rate of attachment of Pasteuria penetrans at 10 endospores/0.1 ml/tube to second-stage juveniles (J2) of Meloidogyne javanica, M. incognita race 1, M. incognita race 3, and M. arenaria races 1 and 2 i...

Meloidogyne incognita-infected tomato seedlings were transplanted into sterilized soil or unsterilized soil collected from 20 California tomato fields to measure suppression caused by Paecilomyces lilacinus, Verticillium chlamydosporium, and other naturally occurring antagonists. Unsterilized soils Q, A, and H contained 35, 39, and 55% fewer M. incognita second-stage juveniles (J2) than did ste...

Ground-state energies for plaquette and dimer order in the J1-J2 square-lattice spin-half Heisenberg model are compared using series expansion methods. We find that these energies are remarkably close to each other at intermediate values of J2 /J1 , where the model is believed to have a quantum disordered ground state. They join smoothly with those obtained from the Ising expansions for the two...

The aim of this study was to investigate the potential using Calotropis procera leaves in vitro and vivo control Meloidogyne incognita race 2 tomato (Solanum lycopersicum). In tests consisted evaluating effect aqueous extract C. (5 10%) on hatching mortality juveniles second stage considering residence time J2 for 24 48 hours. application soil incorporation fresh (50 100 g/kg soil) pots with in...

This review is based on ca. 260 publications, 93 of which included data on the temporal and spatial variation of the concentration of small ions (<1.6 nm in diameter) especially in the lower troposphere, chemical composition, or formation and growth rates of sub-3 nm ions. This information was collected on tables and figures. The small ions exist all the time in the atmosphere, and the average ...

In human cells the length of telomeres depends on telomerase activity. This activity and the expression of the catalytic subunit of human telomerase reverse transcriptase (hTERT) is strongly up-regulated in most human cancers. hTERT expression is regulated by different transcription factors, such as c-Myc, Mad1 and Sp1. In this study, we demonstrated that 15d-PG J2 and rosiglitazone (an endogen...

Arginine is an indispensable amino acid in neonates and is required for growth. Neonatal intestinal epithelial cells (IEC) are capable of arginine transport, catabolism, and synthesis and express nitric oxide (NO) synthase to produce NO from arginine. Our aim was to determine whether arginine directly stimulates IEC growth and protein synthesis and whether this effect is mediated via mammalian ...

It has not been a simple matter to obtain a sound extension of the classical J2 flow theory of plasticity that incorporates a dependence on plastic strain gradients and that is capable of capturing size-dependent behaviour of metals at the micron scale. Two classes of basic extensions of classical J2 theory have been proposed: one with increments in higher order stresses related to increments o...
