The long-term effects of low dietary copper (Cu) intake during pregnancy and lactation on cardiac mitochondria in first-generation adult rats was examined. Rat dams were fed diets containing either low (1 mg/kg Cu) or adequate (6 mg/kg Cu) levels of

The feeding of high-zinc diets to humans is often used as therapy for patients with Wilson’s disease, an autosomal recessive disorder of copper accumulation. There seem to be no outward adverse effects of this treatment; however, preliminary studie

Previous studies suggest that high dietary zinc reduces the copper status of animals by reducing copper transport across the intestinal mucosa. The present study used an enterocyte mimic, the Caco-2 cell, grown on porus membranes as a model to assess

Dietary copper deficiency severely reduces platelet cytochrome c oxidase activity, but the effect of this perturbation on platelet energy metabolism is unknown. In this study, the effect of copper deficiency on platelet adenine nucleotide and GTP con

A histological study was made of dorsal disks (discoidal pores) and associated epidermal cells located on the dorsal surface of abdomens of males of the greenhouse whitefly, Trialeurodes vaporariorum (Westwood). A mean of ≈145 dorsal disks occurred

Morphological and histochemical studies were performed on the flagellar antennal segments of adult Diabrotica virgifera virgifera LeConte (Coleoptera : Chrysomclidae). The work was part of a program to investigate the biological significance of a sol

We have studied two different established insect cell lines capable of synthesizing chitin, UM-BGE-4 from the cockroach and BRL-AG-2 from the boll weevil, for their ability to produce putative cuticle proteins. Mouse polyclonal antibodies were raised

An ultrastructural analysis of cuticle deposition before and after adult eclosion of the cotton boll weevil, Anthonomus grandis Boheman (Coleoptera : Curculionidae), is made to monitor the intra- and extracellular events that accompany the shift in c
