We have studied the role of different conditioning regimens for engraftment of genetically marked hematopoietic repopulating cells in dogs. Peripheral blood (PB) and/or marrow cells collected after treatment with recombinant canine stem cell factor (rcSCF) or cyclophosphamide were transduced in a vector-containing long-term culture system. Three different vector-producing cell lines with simila...

Numerous studies have documented the negative effects of neonicotinoids on bees; it remains crucial to examine how affect other non-target nectar-feeding insects, such as monarch butterfly, Danaus plexippus. Wildflowers growing near agricultural areas can be contaminated with that survival or cause sublethal changes behaviours insects. Nectar residues imidacloprid and clothianidin found in milk...

The relationship(s) between viral virulence and matrix metalloproteinase (MMP) expression in the central nervous system (CNS) of mice undergoing lethal and sublethal infections with neurotropic mouse hepatitis virus was investigated. Lethal infection induced increased levels of MMP-3 and MMP-12 mRNAs as well as that of tissue inhibitor of matrix metalloproteinases 1 (TIMP-1) compared to subleth...

Nesidiocoris tenuis (Reuter) (Hemiptera: Miridae) is an effective predator of multiple pests of vegetable crops, such as thrips, mites, aphids, whiteflies, leafminers. It is mass-reared and released for augmentative biocontrol programs mainly aimed at controlling whiteflies and Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) in greenhouses and open field. We evaluated the lethal and subletha...

Abstract Background Fluoride may induce oxidative stress and apoptosis. It also lead to neurobehavioural defects including neuromuscular damage. The present study aimed explore the effects of sub lethal concentrations sodium fluoride (NaF) on lifespan climbing ability Drosophila melanogaster. In total, 0.6 mg/L 0.8 NaF were selected as sublethal for study. Lifespan was measured activity assay p...

Sustainability in food production is an increasingly discussed issue nowadays; therefore, demands for research that can reduce costs and ensure the quality autonomy of are relevant, with attention to use plants due their importance biodiversity. Thus, objective this was evaluate bioactivity, feeding preference, oviposition preference Miconia albicans botanical extracts at concentrations 1%, 5%,...

John J. Meyer* and James E. Byers Department of Zoology, University of New Hampshire, 46 College Road, Durham, NH 03824, USA *Corresponding: E-mail: [email protected] Abstract Although ecologists have speculated that sublethal predation can impact prey dynamics, consequences of these predator effects have seldom been experimentally tested. In softsediment marine communities, fishes crop extended ...

the elm leaf beetle xanthogaleruca luteola müller (coleoptera: chrysomelidae), is a serious pest of elm (ulmus spp.) throughout iran. in the present study, lethal and sublethal effects of neem, achook® containing 0.03% azadirachtin, were assessed on mortality, growth, larval weight and feeding deterrence as well as enzymatic and non-enzymatic activities of third instar larvae of the elm leaf be...
