  • Edible oils are mainly vegetable oils which have been subjected to several processes to removed undesirable constituents. In order to make them suitable for human consumption, most edible oils are subjected to refining processes, such as neutralization, bleaching and deodorization. Among edible oils, only virgin olive oil (a natural juice obtained by olive pressing), can be consumed without refining. Edible oils are characterized by a wide range of physical and chemical prop-erties, since their composition depend on the type of oil (Rossell1991).

  • As our understanding of human genetics has increased at an explosive rate over the last half century, genetic knowledge has become more relevant to us and to those we love. In the 1990s and early 2000s, scientists mapped the human genome and began to understand the ways in which a variety of different genes function in human beings. Their initial goal was to gain information and insight into how the genes we are born with might affect our lives and the lives of our children.

  • The cuticles of most insect larvae have a variety of melanin patterns that function in the insects’ interactions with their biotic and abiotic environ-ments. Larvae of the armywormPseudaletia separatahave black and white stripes running longitudinally along the body axis. This pattern is empha-sized after the last larval molt by an increase in the contrast between the lines.

  • Cyclic nucleotide specific phosphodiesterases (PDEs) are important components of all cAMP signalling networks. In humans, 11 different PDE families have been identified to date, all of which belong to the class I PDEs. Pharmaco-logically, theyhavebecome of great interest as targets for the development of drugs for a large variety of clinical condi-tions. PDEs in parasitic protozoa have not yet been exten-sively investigated, despite their potential as antiparasitic drug targets.

  • 4-Hydroxy-2-trans-nonenal (4-HNE), one of the major end products of lipid peroxidation, has been shown to induce apoptosis in a variety of cell lines. It appears to modulate signalingprocesses inmore thanonewaybecause it has been suggested to have a role in signaling for differentiation and proliferation. We showfor the first time that incorporation of 4-HNE-metabolizing glutathioneS-transferase (GST) isozyme, hGSTA4-4, into adherent cell lines HLE B-3 and CCL-75, by either cDNA transfection or microinjection of active enzyme, leads to their transformation. ...

  • Data on the adoption of three GGDP-generated maize technologies—modern varieties (MVs), fertilizer recommendations, and plant configuration recommendations—were collected through a national survey of maize growers conducted between November 1997 and March 1998. A three-stage, clustered, randomized procedure was used to select a representative sample of 420 maize farmers.

  • Whereas significant knowledge is accumulating on the antibacterial and antifungal properties of host defense peptides (HDPs) and their synthetic mimics, much less is known of their activities against parasites. A variety ofin vitro andin vivo antiparasitic assays suggest that these notorious anti-microbial compounds could represent a powerful tool for the development of novel drugs to fight parasites in the vertebrate host or to complement current therapeutic strategies

  • The Navigenics services provide insight into patients’ health risks by determining their individual genetic load for a variety of conditions and medication sensitivities where genetic risk factors are well established. The conditions included in Navigenics’ analysis are those that are clinically actionable and those that contribute to the major burden of disease in the United States, such as myocardial infarction, cancer, and type 2 diabetes.

  • A variety of scientific disciplines have set as their task explaining mental activities, recognizing that in some way these activities depend upon our brain. But, until recently, the opportunities to conduct experiments directly on our brains were limited. As a result, research efforts were split between disciplines such as cognitive psychology, linguistics, and artificial intelligence that investigated behavior, while disciplines such as neuroanatomy, neurophysiology, and genetics experimented on the brains of non-human animals.

  • African educators and overseas friends came together from 4 to 9 December 1995 — about 100 from four continents and 14 countries, women and men, their ages from under 30 to over 80. Included were ministry officials and university administrators, scientists and classroom teachers, innovators or researchers into teaching, and teachers of teachers. Eleven main papers, authored in advance and by Africans, were the basis of our discussion, though all participants spoke as critics, proponents, and commentators.

  • Strong increase in the production of genetically modified organisms (GMOs) observed over the years has led to a consolidation of transgenic seed industries worldwide. The dichotomy between the evaluated risk and the perceived risk of transgenic use has defined their level of acceptability among different global societies. GMOs have been widely applied to agricultural commodities, among them the Roundup Ready™ (RR™) soybean line GTS 40-3-2 has become the most prevalent transgenic crop in the world.

  • Abstract Resistance to conventional anticancer therapies in patients with advanced solid tumors has prompted the need of alternative cancer therapies. Moreover, the success of novel cancer therapies depends on their selectivity for cancer cells with limited toxicity to normal tissues. Several decades after Coley's work a variety of natural and genetically modified non-pathogenic bacterial species are being explored as potential antitumor agents, either to provide direct tumoricidal effects or to deliver tumoricidal molecules.

  • Eukaryotic genomes are full of long terminal repeat (LTR) retrotransposons. Although most LTR retrotransposons have common structural features and encode similar genes, there is nonetheless considerable diversity in their genomic organization, reflecting the different strategies they use to proliferate within the genomes of their hosts. reports deposited research Transposons are mobile genetic elements that can multiply in the genome using a variety of mechanisms. Retrotransposons replicate through...
