    Origin of new genes: evidence from experimental and computational analyses

    Exon shuffling is an essential molecular mechanism for the formation of new genes. Many cases of exon shuffling have been reported in vertebrate genes. These discoveries revealed the importance of exon shuffli...

    Correlation of Acute Prostacyclin Response in Primary (Unexplained) Pulmonary Hypertension with Efficacy of Treatment with Calcium Channel Blockers and Survival

    Unexplained, or primary, pulmonary hypertension, is usually a rapidly fatal disease, in which the use of vasodilator therapy is controversial (14, 22, 25). While some authors have proposed that there may be a ...

    Biosynthesis and Endocytosis of Yolk Proteins in the Mosquito

    The maturation of insect eggs requires the fat body production of large amounts of a protein, vitellogenin (Vg), that is secreted into the hemolymph, selectively accumulated by the oocytes and stored in yolk b...

    The Larch Casebearer in the Intermountain Northwest

    The larch casebearer, Coleophora laricella Hubner (Lepidoptera: Coleophoridae), is a small silver-gray moth whose larvae mine needles of larches, Larix spp. Apparently of European origin, this defoliator was firs...

    Genetic Aspects of Symbiotic Nitrogen Fixation

    Nitrogen fixation is the reduction of molecular dinitrogen (N2) to ammonia. This process, along with nitrate reduction, brings nitrogen from inorganic form into the organic world, for ammonia is the form of nitro...
