Initially, exploitation of interactions between plants and other organisms, particularly insect pests, foundered b...

Much bioethical discussion has been devoted to the subject of human enhancement through various technological means such as genetic modification. Although many of the same technologies could be, indeed in many cases already have been, applied to non-human animals, there has been very little consideration of the concept of "animal enhancement", at least not in those specific terms. This paper ad...

The use of donor sperm or egg for reproduction raises the issue of the right of donor-conceived individuals to know their genetic origins. This paper argues in favor of acknowledging such a right and explores the challenges that cross-border medically assisted reproduction would raise in relation to it. It first explores possible justifications for such a right by discerning its possible concep...

The variation in nutrient content is important because of the effects it can have in meeting nutritional requirements. It is therefore important to analyse the composition of the genetically modified food and to establish the extent to which the product is equivalent to its non-genetically modified counterpart. Statistically significant differences in composition may warrant closer examination ...

A series of protocols are presented for the storage, growth, transformation, and characterization of wild type and mutant strains of Synechocystis sp. strain PCC 6803. These protocols include the isolation of genomic DNA and the strategies required for the construction of specific gene interruptions or deletions in this organism. This cyanobacterium has been used widely as a model for photosynt...

Malnutrition is associated with an inadequate diet, poor health and sanitation services and inadequate care for young children. A combination of income growth and nutrition interventions are therefore suggested to adequately tackle this issue [Haddad, L., Alderman, H., Appleton, S., Song, L., Yohannes, Y., 2003. Reducing child malnutrition: how far does income growth take us? World Bank Econ. R...

Labeling proteins with high specificity and efficiency is a fundamental prerequisite for microscopic visualization of subcellular protein structures and interactions. Although the comparatively small size of epitope tags makes them less perturbative to fusion proteins, they require the use of large antibodies that often limit probe accessibility and effective resolution. Here we use the covalen...

A triplex-forming oligonucleotide (TFO) could be a useful molecular tool for gene therapy and specific gene modification. However, unmodified TFOs have two serious drawbacks: low binding affinities and high sequence-dependencies. In this paper, we propose a new strategy that uses a new set of modified nucleobases for four-base recognition of TFOs, and thereby overcome these two drawbacks. TFOs ...

Food choices established during childhood and adolescence tend to persist into adulthood with consequences for long-term health. Yet, to date, relatively little research has examined factors that influence the food choices of children and adolescents from their perspectives. In this article, previous research is extended by examining developmental differences between children's and adolescents'...

Latest estimates indicate that nutritional deficiencies account for 3 million child deaths each year in less-developed countries. Targeted nutritional interventions could therefore save millions of lives. However, such interventions require careful optimization to maximize benefit and avoid harm. Progress toward designing effective life-saving interventions is currently hampered by some serious...
