    Description: The human malaria parasite Plasmodium vivax is responsible for 25-40% of the approximately 515 million annual cases of malaria worldwide. Although seldom fatal, the parasite elicits severe and incapacitating clinical symptoms and often causes relapses months after a primary infection has cleared. Despite its importance as a major human pathogen, P. vivax is little studied because it cannot be propagated continuously in the laboratory except in non-human primates. We sequenced the genome of P. vivax to shed light on its distinctive biological features, and as a means to drive development of new drugs and vaccines. Here we describe the synteny and isochore structure of P. vivax chromosomes, and show that the parasite resembles other malaria parasites in gene content and metabolic potential, but possesses novel gene families and potential alternative invasion pathways not recognized previously. Completion of the P. vivax genome provides the scientific community with a valuable resource that can be used to advance investigation into this neglected species.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2651158/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2651158/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carlton, Jane M -- Adams, John H -- Silva, Joana C -- Bidwell, Shelby L -- Lorenzi, Hernan -- Caler, Elisabet -- Crabtree, Jonathan -- Angiuoli, Samuel V -- Merino, Emilio F -- Amedeo, Paolo -- Cheng, Qin -- Coulson, Richard M R -- Crabb, Brendan S -- Del Portillo, Hernando A -- Essien, Kobby -- Feldblyum, Tamara V -- Fernandez-Becerra, Carmen -- Gilson, Paul R -- Gueye, Amy H -- Guo, Xiang -- Kang'a, Simon -- Kooij, Taco W A -- Korsinczky, Michael -- Meyer, Esmeralda V-S -- Nene, Vish -- Paulsen, Ian -- White, Owen -- Ralph, Stuart A -- Ren, Qinghu -- Sargeant, Tobias J -- Salzberg, Steven L -- Stoeckert, Christian J -- Sullivan, Steven A -- Yamamoto, Marcio M -- Hoffman, Stephen L -- Wortman, Jennifer R -- Gardner, Malcolm J -- Galinski, Mary R -- Barnwell, John W -- Fraser-Liggett, Claire M -- N01 AI030071/AI/NIAID NIH HHS/ -- R01 AI064478/AI/NIAID NIH HHS/ -- R01 AI064478-05/AI/NIAID NIH HHS/ -- R01 GM070793/GM/NIGMS NIH HHS/ -- R01 GM070793-01A2/GM/NIGMS NIH HHS/ -- R01 GM083873/GM/NIGMS NIH HHS/ -- R01 LM006845/LM/NLM NIH HHS/ -- R01 LM006845-09/LM/NLM NIH HHS/ -- England -- Nature. 2008 Oct 9;455(7214):757-63. doi: 10.1038/nature07327.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Institute for Genomic Research/J.

    Notes: Abstract The inclusion complex of benzaldehyde (BA) with β-cyclodextrin (β-CD) was prepared and was studied by thermal analysis and X-ray diffractometry. The composition of the complex was identified by TG and elemental analysis as β-CD·BA·9H2O. TG and DSC studies showed that the thermal dissociation of β-CD·BA·9H2O took place in three stages: dehydration in the range 70-120°C; dissociation of β-CD·BA in the range 235-270°C; and decomposition of β-CD above 280°C. The kinetics of dissociation of β-CD·BA in flowing dry nitrogen was studied by means of TG both at constant temperature and at linearly increasing temperature. The results showed that the dissociation of β-CD·BA was dominated by a one-dimensional random nucleation and subsequent growth process (A2). The activation energy E was 124. 8 kJ mol-1, and the pre-exponential factor A 5.04·1011 min-1.

    Notes: Abstract The stability of β-cyclodextrin·ethyl benzoate·6H2O(β-CD·C6H5COOC2H5·6H2O) was investigated by TG and DSC. The mass loss takes place in three stages: the dehydration occurs at 50-120°C; the dissociation of β-CD·C6H5COOC2H5occurs at 200-260°C; the decomposition of β-CD begins at 280°C. The kinetics of the dissociation of β-CD·C6H5COOC2H5in a dry nitrogen flow was studied by means of thermogravimetry both at constant temperature and linearly increasing temperature. The results show that the dissociation of β-CD·C6H5COOC2H5is dominated by a three-dimensional diffusion process (D3). The activation energy E is 116.19 kJ mol-1and the pre-exponential factor A 6.5358·109min-1. Cyclodextrin is able to form inclusion complexes with a great variety of guest molecules, and the studies focus on the energy of binding between cyclodextrin and the guest molecule. In this paper, the β-cyclodextrin·ethyl benzoate inclusion complex was studied by fluorescence spectrophotometry and infrared absorption spectroscopy, and the results show that the stable energy of inclusion complexes of β-CD with weakly polar guest molecules consists mainly of van der Waals interaction.
