ISSN: 1471-6402Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: PsychologyNotes: This paper examines the psychological implications of the migratory process on Latin American women in the United States, addressing is-sues of gender roles, acculturation, language, loss, and grief that are frequently presented by immigrant Latinas in psychotherapy. The paper interprets these issues as reflective of the stresses created by the migratory process rather than as issues of individual psychopathology, and suggests ways to respond to them through psychotherapy.Type of Medium: Electronic ResourceURL: -

ISSN: 1095-8649Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: BiologyNotes: Examination of 450 specimens of Macruronus magellanicus from two fishing grounds in southern Chile (Talcahuano: 36°40'S, Punta Arenas: 54° S) revealed 24 205 metazoan parasites, belonging to 15 taxa with low specificity: Chondracanthus australis and Neobrachiella sp. (Copepoda); Elytrophalloides oatesi, Gonocerca phycidis, Derogenes varicus and Brachyphallus parvus, (Digenea); Hepatoxylon trichiuri, Scolex pleuronectis, Clestobothrium crassiceps, Grillotia dollfusi, Pseudophyllidea gen. sp. (Cestoda); Anisakidae, Cucullanus sp. (Nematoda), Corynosoma australe and Acanthocephala gen. sp. (Acanthocephala). The list includes parasites that are common to other merluccids from the zone. The parasitological evidence does not suggest the existence of two discrete stocks, but the existence of a migratory process from south to north.Type of Medium: Electronic ResourceURL: -

Published 1989Staff ViewISSN: 1744-313XSource: Blackwell Publishing Journal Backfiles 1879-2005Topics: BiologyMedicineNotes: The expression of HLA class I and II antigens was analysed in 30 primary gastric carcinomas, 27 autologous lymph node metastases and 25 autologous gastric mucosae. We used an immune alkaline phosphatase technique on cryostatic sections and mAbs directed against HLA class I monomorphic determinants, HLA-B locus-specific products and HLA-DR, -DP and -DQ molecules. In addition HLA class I genes were analysed in tumour tissue and compared by Southern blots with the RFLP from autologous mucosa using locus-specific HLA probes. Finally the infiltrating mononuclear cells were studied on gastric tumours and adjacent mucosa with mAbs defining CD4, CD8 and CD11b differentiation antigens.The results obtained showed that three out of 27 primary gastric carcinomas completely lack HLA-ABC antigens (10%). In addition, two primary tumours presented a variable expression. The remaining 22 tumours presented a homogeneous positive HLA class I expression. Interestingly, when the autologous mucosa was analysed, only 12 out 25 specimens were homogeneously stained with mAbs against HLA class I antigens, suggesting that this tissue may lack the expression of HLA antigens before becoming malignant. Indeed, the majority of the gastric carcinomas studied presented a higher HLA-ABC antigenic expression than autologous mucosa. Finally, the HLA expression observed in the primary tumour was similar to that observed in autologolous metastases.As a second part of the study we have found a direct relationship between the expression of HLA-DR antigens in mucosa and the intensity of inflamatory infiltration. This relationship was not maintained in the tumour tissue. In the mucosa the CD4-positive T cell was the predominant lymphocyte, while it was CD8 in the HLA-DR-positive tumours.Type of Medium: Electronic ResourceURL: -

The simple ”big leaf” Penman-Monteith model was used to estimate canopy transpiration. During the study period the predawn leaf water potential varied from –0.4 to –1.3 MPa, with the minimum values observed in the winter months (June and August 1996), while the average estimated values for canopy conductance and canopy transpiration fell from 17.3 to 5.8 mm s–1 and from 0.54 to 0.18 mm h–1, respectively. On the basis of all measurements, the average value of the decoupling coefficient was 0.25. During continuous soil water shortage a proportional reduction was observed in predawn leaf water potential and in daily maximum values of stomatal conductance, canopy transpiration and decoupling coefficient. The results showed that water vapour exchange in this canopy is strongly dominated by the regional vapour pressure deficit and that canopy transpiration is controlled mainly by stomatal conductance. On a seasonal basis, stomatal conductance and canopy transpiration were mainly related to predawn leaf water potential and, thus, to soil moisture and rainfall. Good results were obtained with a multiplicative empirical model that uses values of photosynthetically active radiation, vapour pressure deficit and predawn leaf water potential to estimate stomatal conductance.Type of Medium: Electronic ResourceURL: -

Published 2000Staff ViewISSN: 0931-1890Keywords: Key words Eucalyptus grandis ; Leaf water potential ; Net photosynthetic rate ; Stomatal conductance ; Water supplySource: Springer Online Journal Archives 1860-2000Topics: BiologyAgriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: Abstract In order to determine how environmental and physiological factors affect leaf gas exchange in a 9-year-old clonal eucalypt plantation (Eucalyptus grandis Hill ex. Maiden hybrids) in the State of Espirito Santo, Brazil, the diurnal patterns of predawn leaf water potential (Ψpd), and leaf gas exchange were monitored from November 1995 to August 1996. Soil water content (Θ) and microclimatic variables were also recorded. Most of the rainfall during the experimental period occurred from October to December 1995 and from March to April 1996, causing a significant variation in Θ and Ψpd. A high positive correlation (r 2=0.92) was observed between Ψpd and Θ measured at 0.3 m depth from the soil surface. During conditions of high soil water availability, the maximum values of stomatal conductance for water vapor (g s) and net photosynthetic rate (A) were over 0.4 mol m–2 s–2 and l5 µmol m–2 s–1, respectively. The results showed that Ψpd and leaf gas exchange of the examined trees were susceptible to changes in the water content of the upper soil layers, where the major concentration of active roots occur. Multiple linear regression analysis indicated that photosynthetic active radiation (Q), vapor pressure deficit (VPD), atmospheric CO2 molar fraction (C a), and Ψpd were the most important factors controlling g s whereas Q and VPD were the main microclimatic variables controlling A.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-2234Keywords: Key words: Rubisco mechanism ; Transition-state structures ; Ab initio calculationsSource: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Abstract. The carboxylation and oxygenation processes of a model substrate, 3,4-dihydroxy-2-pentanone, have been theoreticaly characterized as a set of steps, mimicking the corresponding reactions of D-ribulose-1,5-bisphosphate catalyzed by rubisco. A theoretical characterization is carried out of transition-state structures and possible molecular intermediates represented as saddle points of index 1 and minimum energy structures, respectively. The quantum chemical characterization, at the HF/3-21G calculation level, of these stationary points is used to rationalize and to discuss both catalyzed sequences. The reported set of these stationary points maps out most experimental aspects of the reaction pathways for the real system.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-2234Keywords: Key words: Rubisco ; Carboxylation step ; QM/MM ; Hybrid theoretical calculations ; Transition state structureSource: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Abstract. The present study elucidates structural features related to the molecular mechanism in the carboxylation step of the reaction catalyzed by Rubisco. Starting from the initial X-ray Protein Data Bank structure of a Rubisco monomer, the reactive subsystem in vacuo is subjected to quantum chemical semiempirical and ab initio studies, while the effects of the protein environments are included by means of a hybrid quantum mechanical/molecular mechanical (QM/MM) approach. The QM/MM is used to characterize the transition structure for carboxylation inside the protein. The calculations were made with the AM1/CHARMM/GRACE scheme. Comparisons between the in vacuo and in situ transition structures show remarkable invariance with respect to geometric parameters, index and transition vector amplitudes. The transition state couples the carbon dioxide attack to the C2 center of the substrate in its dienol form with a simultaneous intramolecular hydrogen transfer from the C2 atom to the hydroxyl group linked to the C3 center. This study suggests that carboxylation may be simultaneously coupled to the activation of the C3 center in the enzyme.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-5052Source: Springer Online Journal Archives 1860-2000Topics: BiologyDescription / Table of Contents: Resumen Investigaciones sobre la resistencia a la sequía de especies leñosas siempreverdes de la regiòn Patagónica. En el Sur de Chile se ubican sucesivamente hacia la región austral cuatro formaciones vegetales: bosques esclerofílicos (áridos), bosques caducifolios templados (semihúmedos a húmedos), pluviisilvas norpatagonicas y subantarticas (húmedas a muy húmedas, templadas a frías). La región valdiviana (38–42° L.S.) es una zona de transición, en donde se reunen especies fundamentalmente de las últimas tres formaciones. De estas se eligieron 53 especies leñosas siempreverdes, para investigar algunas de sus propiedades relacionadas con la resistencia a la sequía. Las especies de las pluviisilvas húmedas manifiestan un alto grado de xeromorfía en el tamaño de las hojas, desarrollo de la superficie y esclerofilia. De esto se deduce una adaptación a los frecuentes vientos fuertes en la Patagonia Sur. En cambio, las especies de la región más seca de los bosques caducifolios no poseen una resistencia mecánica tan notable. Sin embargo, en éstas se observa una transpiración mínima (cuticular) reducida. Esta importante propiedad de resistencia a la sequia, evita una pérdida elevada de agua en períodos secos. Especies de la pluviisilva norpatagónica no poseen una resistencia constitucional del tipo mencionado últimamente. Aquellas que avanzan más hacia el Sur la poseen en grado menor. Sin embargo, en estas ultimas existe una resistencia plasmática elevada. Esta contradicción se explica en base de datos climáticos. En la region surpatagónica el invierno trae consigo un recargo en la economia hídrica de la planta. En esta estación se observa deficits de saturación considerables. Temperaturas bajas dificultan la absorción y conducción del agua y la humedad relativa del aire permanentemente alta, disminuye la efectividad de la cutícula. Ademas los vientos fuertes favorecen la entrega de agua. Por lo tanto se explica, que las especies en cuestión recurran a la resistencia plasmática y puedan soportar así grandes déficits de agua.Notes: Zusammenfassung In Südchile folgen in südlicher Richtung vier Vegetationsgebiete aufeinander: Hartlaubwälder (arid), temperierte Sommerwälder (semihumid — humid), nordpatagonische und subantarktische Regenwälder (humid — perhumid, temperiert bis kühl). In der valdivianischen Übergangszone zwischen 38–42° südl. Br. treffen sich Florenelemente insbesondere der letzten drei Formationen. Unter diesen wurden 53 immergrüne Gehölze ausgewählt und einige ihrer Resistenzeigenschaften untersucht. Die Arten der feuchten Regenwälder weisen mit den Merkmalen Blattgröße, Oberflächenentwicklung und Hartlaubcharakter einen hohen Xeromorphiegrad auf. Darin wird eine Anpassung an die häufigen stürmischen Winde in Südpatagonien gesehen. Die Arten des trockeneren Sommerwaldgebietes besitzen dagegen keine so auffallend gesteigerte mechanische Resistenz. Bei diesen wird jedoch eine erheblich reduzierte Minimal- (Cuticular-) Transpiration festgestellt. Mit dieser echten Dürreresistenzeigenschaft sind sie dafür eingerichtet, in trockenen Perioden übermäßig große Wasserverluste zu vermeiden. Auf den nordpatagonischen Regenwald beschränkte Arten verfügen über keine und die weiter nach Süden vordringenden nur über eine geringe konstitutionelle Resistenz der zuletzt erwähnten Art. Bei diesen ist stattdessen eine erhöhte plasmatische Resistenz vorhanden. Dieser Gegensatz wird anhand klimatischer Daten erörtert. Im südpatagonischen Gebiet bringt der Winter eine besonders starke Belastung des Wasserhaushalts mit sich. In dieser Jahreszeit können erhebliche Unterbilanzen auftreten. Niedrige Temperaturen behindern die Aufnahme und Leitung des Wassers, permanent hohe Luftfeuchtigkeit vermindert die Wirksamkeit des cuticulären Diffusionswiderstandes und ferner mögen die heftigen Winde die Wasserabgabe fördern. Somit ist es erklärlich, daß die betreffenden Arten vorwiegend auf die plasmatische Resistenz ausweichen und dafür eingerichtet sind, große Wasserverluste zu ertragen.Type of Medium: Electronic ResourceURL: -
