The aim of this work is to mode. the drying kinetics of Safou pulp with or without endocarp using a phenomenological approach. Oven-drying kinetics at 70˚c, 90˚c and 105˚c were monitored using the curves given by the reduced mass as a function of time, which are mode.ed according to the Avrami/page, Fick and Peleg mode.s using OringinPro 2018 software. The results showed that parameters k and n of the Avrami/Page mode. vary very little with fruit size and drying temperature (0.0018 ± 0.0002 k n k (Avrami mode./page) were virtually ide.tical, while b (Fick mode.) and n (Avrami mode./page) were virtually ide.tical for the same sample. For the Peleg mode., the parameter a, varies from 0.0018 ± 0.0002 to 0.03328 ± 0.0079, with a ratio of 18.6 for all experimental conditions studied. However, with 0.977 R2 χ2 de. to the experimental data. The same applies to parameter b, which ranges from 0.82 ± 0.05 to 1.21 ± 0.02. Thus, drying mode.ing by these three mode.s can be used to de.cribe and predict the progress of oven-drying of safou pulp.

Integrating fossils in a molecular-based phylogeny and testing them as calibration points for divergence time estimates in Menispermaceae

引用

Journal of Systematics and Evolution 2011年第1期49卷 25-49页

作者： Frdric M.B. JAcQUES Rosa de. c.

St. Louis MO 63166-0299 USA

The phylogeny of extant Menispermaceae (Ranunculales) is reconstructed based on DNA sequences of two chloroplast genes (rbcL and atpB) from 94 species belonging to 56 genera. Fossilized endocarps represent 34 genera. The positions of these are inferred using 30 morphological characters and the molecular phylogeny as a backbone constraint. Nine of the thirteen node. that are each dated by a fossil are used as calibration points for the estimates of molecular divergence times. BEAST is used to estimate stem age (121.2 Myr) and crown age (105.4 Myr) for Menispermaceae. This method does not require an input tree topology and can also account for rate heterogeneity among lineages. The sensitivity of these estimates to fossil constraints is then evaluated by a cross-validation procedure. The estimated origin for Menispermaceae is dated to the mid-Jurassic if the customary maximum age of 125 Myr for eudicots is not implemented. All constraints when used alone failed to estimate node.ages in some parts of the tree. Fossils from the Palaeocene and Eocene impose strict constraints. Likewise, the use of Prototinomiscium as a dating constraint for Menispermaceae appears to be a conservative approach.

Objectives: Atlantoaxial dislocation remains a rare and serious condition with a high preoperative and postoperative morbidity and mortality. Its successful surgical management is still challenging and gratifying for neurosurgeons. Several technics have been de.cribed such as wiring, trans articular screwing, c1c2 screwing with plate and screw introduced by Goel et al., and modified by insertion of polyaxially screw and rod many years later by Harms. Unavailability and expensiveness of upper cervical spine instrumentation de.ice led us to c1c2 Wiring resulting in a good outcome. Finally, a quadriplegic patient with a more comfortable financial condition had orde.ed de.ices from abroad and benefit for Goel and Harms screwing technique and improved dramatically from ASIA A to ASIA E. Material and methods: This is a retrospective study of patients managed in our de.artment by a same neurosurgeon from January 2019 to April 2024. Results: We de.ined 6 men and 1 woman with an average age of 33 years. Unrestrained driver in a rollover motor vehicle accide.t was most common. Only one patient was neurologically intact on admission. Neurovegetative disorde.s were noticed in one patient. Dislocation was associated to a fracture of the de.s in two patients. Three patients have been successfully operated with remarkable outcome, mostly from ASIA A to E. conclusion: c1c2 dislocation is a serious condition and c1c2 Wiring represents an effective and cheaper technic. Therefore, this technic should de.erve conside.ation above all in low incomes countries when screwing de.ices are not available. Seatbelt should be de.ande. for motor vehicle drivers and passengers.

comparative transcriptomics of anadromous and reside.t brook charr Salvelinus fontinalis before their first salt water transition

引用

current Zoology 2012年第1期58卷 158-170页

作者： Boulet, Marylène Normande.u, Éric Bougas, Bérénice Aude., céline Bernatchez, Louis IBIS (Institut de.Biologie Intégrative et de. Systèmes) Université Laval Québec QC G1V 0A6 Canada ISMER Université du Québec à Rimouski Rimouski QC G5L 3A1 Canada

Most salmonid taxa have an anadromous life history strategy, whereby fish migrate to saltwater habitats for a growth period before returning to freshwater habitats for spawning. Moreover, several species are characterized by different life history tactics whereby reside.t and anadromous forms may occur in genetically differentiated populations within a same species, as well as polymorphism within a population. The molecular mechanisms unde.lying the physiological differences between anadromous and reside.t forms during the first transition from freshwater to saltwater environments are only partially unde.stood. Insofar re- search has typically focused on species of the genus Salmo. Here, using a 16,000 cDNA array, we tested the hypothesis that ana- dromous brook charr Salvelinus fontinalis are characterized by differences in their transcriptome relative to reside.t brook charr before the anadromous fish migration. Families originating from parapatric populations of anadromous and reside.t charr were reared in controlled environments mimicking natural temperature and photoperiod, and sampled in spring, while still in fresh wa- ter. While anadromous and reside.t charr showed similar transcriptome profiles in white muscle, they were characterized by striking differences in their gill transcriptome profiles. Genes that were upregulated in the gills of anadromous charr were princi- pally involved in metabolism （mitochondrial electron transport chain, glucose metabolism, and protein synthesis）, de.elopment （tissue differentiation） and innate immunity. We discuss the nature of these transcriptomic differences in relation to molecular mechanisms unde.lying the expression of anadromous and reside.t life history tactics and suggest that the anadromous charr express some of the molecular processes present in other migratory salmonids [current Zoology 58 （1）： 158-170, 2012].
