As Residências Cistercienses em S. Bento de Cástris que se vêm realizando desde 2013 têm como primeiro objectivo reinventar na contemporaneidade a densidade histórica do discurso cisterciense, integrando a realidade deste mosteiro tanto numa ampla geografia da Ordem de Cister em Portugal e na Europa, como na história da região e do país. Inspiradas nas questões da História, da Arte, da Arquitectura, da Música, do Património e da Paisagem, as Residências Cistercienses em Cástris vêm apostando no debate de questões actuais ligadas aos espaços monásticos e ao seu futuro, nomeadamente os cistercienses. Esta aposta concretiza-se também no presente trabalho, DO ESPÍRITO DO LUGAR. ESTÉTICA. SILÊNCIO, ESPAÇO, LUZ, resultado das I e II Residências Cistercienses (2013 e 2014), e integra estudos que se reportam especialmente ao Silêncio e às suas várias linguagens e significados e às dimensões da Estética monástico-religiosa, com algum privilégio para as temáticas da Música. A apropriação do mosteiro pelo silêncio e pela música e a apreciação do espólio musical e instrumental de S. Bento de Cástris permitem uma melhor percepção das diversidades conjunturais e dos seus ritmos, aliando-se às dimensões de valorização patrimonial, eacompanhando-as de sugestões estéticas na pintura, escultura, pintura mural, azulejaria…, no sentido da fruição plena dos espaços. A riqueza deste evento, a Residência Cisterciense no mosteiro de S. Bento de Cástris, permitirá que o futuro deste património, de tanta diversidade e espessura histórico-cultural, continue a ser debatido e a justificar edições futuras resultantes dos trabalhos de investigação aí apresentados e debatidos.

Both (I) and (II) crystallize in a cisoid conformation for the carbonyl group and alkoxy groups. Compounds (I) and (II) are photostable on irradiation in the solid state in spite of the favourable conformation of the functional groups for intramolecular H abstraction. Absence of photoreaction of (I)and (II) in the solid state is rationalized in the light of unfavourable intramolecular geometry.

I. The binding of the intercalating dye ethidium bromide to closed circular SV 40 DNA causes an unwinding of the duplex structure and a simultaneous and quantitatively equivalent unwinding of the superhelices. The buoyant densities and sedimentation velocities of both intact (I) and singly nicked (II) SV 40 DNAs were measured as a function of free dye concentration. The buoyant density data were used to determine the binding isotherms over a dye concentration range extending from 0 to 600 µg/m1 in 5.8 M CsCl. At high dye concentrations all of the binding sites in II, but not in I, are saturated. At free dye concentrations less than 5.4 µg/ml, I has a greater affinity for dye than II. At a critical amount of dye bound I and II have equal affinities, and at higher dye concentration I has a lower affinity than II. The number of superhelical turns, τ, present in I is calculated at each dye concentration using Fuller and Waring's (1964) estimate of the angle of duplex unwinding per intercalation. The results reveal that SV 40 DNA I contains about -13 superhelical turns in concentrated salt solutions.

The free energy of superhelix formation is calculated as a function of τ from a consideration of the effect of the superhelical turns upon the binding isotherm of ethidium bromide to SV 40 DNA I. The value of the free energy is about 100 kcal/mole DNA in the native molecule. The free energy estimates are used to calculate the pitch and radius of the superhelix as a function of the number of superhelical turns. The pitch and radius of the native I superhelix are 430 Å and 135 Å, respectively.

A buoyant density method for the isolation and detection of closed circular DNA is described. The method is based upon the reduced binding of the intercalating dye, ethidium bromide, by closed circular DNA. In an application of this method it is found that HeLa cells contain in addition to closed circular mitochondrial DNA of mean length 4.81 microns, a heterogeneous group of smaller DNA molecules which vary in size from 0.2 to 3.5 microns and a paucidisperse group of multiples of the mitochondrial length.

II. The general theory is presented for the sedimentation equilibrium of a macromolecule in a concentrated binary solvent in the presence of an additional reacting small molecule. Equations are derived for the calculation of the buoyant density of the complex and for the determination of the binding isotherm of the reagent to the macrospecies. The standard buoyant density, a thermodynamic function, is defined and the density gradients which characterize the four component system are derived. The theory is applied to the specific cases of the binding of ethidium bromide to SV 40 DNA and of the binding of mercury and silver to DNA.

Ovarian follicle development is primarily regulated by an interplay between the pituitary gonadotrophins, LH and FSH, and ovary-derived steroids. Increasing evidence implicates regulatory roles of transforming growth factor-beta (TGF beta) superfamily members, including inhibins and activins. The aim of this study was to identify the expression of mRNAs encoding key receptors of the inhibin/activin system in ovarian follicles ranging from 4 mm in diameter to the dominant F1 follicle (similar to 40 turn). Ovaries were collected (n=16) from inid-sequence hens maintained on a long-day photoschedule (16h of light:8 h of darkness). All follicles removed were dissected into individual granulosa and thecal layers. RNA was extracted and cDNA synthesized. Real-time quantitative PCR was used to quantify the expression of niRNA encoding betaglycan, activin receptor (ActR) subtypes (type-I, -IIA and -IIB) and glyceraldehyde-3-phosphate dehydrogenase (GAPDH); receptor expression data were normalized to GAPDH expression. Detectable levels of ActRI, -IIA and -IIB and the inhibin co-receptor (betaglycan) expression were found in all granulosa and thecal layers analysed. Granulosa ActRI mRNA peaked (P < 0(.)05) in 8-9(.)9 mm follicles, whereas ActRIIA rose significantly from 6-7(.)9 mm to 8-9(.)9 nun, before filling to F3/2; levels then rose sharply (3-fold) to F1 levels. Granulosa betaglycan niRNA expression rose 3-fold from 4-5(.)9 min to 8-9(.)9 mm, before falling 4-fold to F3/2; levels then rose sharply (4-fold) to F1 levels. ActRIIB levels did not vary significantly during follicular development. Thecal ActRI mRNA expression was similar from 4-7(.)9 mm then decreased significantly to a nadir at the F4 position, before increasing 2-fold to the F1 (P < 0(.)05). Although thecal ActRIIB and -IIA expression did not vary significantly from 4 nim to F3, ActRIIB expression increased significantly (2-fold) from F3 to F1 and ActIIA, increased 22-fold from F2 to F1 (P < 0(.)05). Thecal betaglycan fell to a nadir at F6 after follicle selection; levels then increased significantly to F2, before filling similar to 50% in the F I. In all follicles studied expression of betaglycan and ActRI (granulosa: 1-0(.)65, P < 0-001, n=144/group; theca: r=0(.)49, P < 0-001, n=144/group) was well correlated. No significant correlations were identified between betaglycan and ActRIIA or -IIB. Considering all follicles analysed, granulosa mRNA expression of betaglycan, ActRI ActRIIA and ActRIIB were all significantly lower than in corresponding thecal tissue (betaglycan, 11(.)4-fold; ActRIIB, 5(.)1-fold; ActR(.) 3-8-fold: ActRIIA, 2(.)8-fold). The co-localization of type-I and -II activin receptors and betaglycan on granulosa and thecal cells are consistent with a local auto/paracrine role of inhibins and activins in modulating ovarian follicle development, selection and progression in the domestic fowl.

CD95 (Fas/Apo-1)-mediated apoptosis was shown to occur through two distinct pathways. One involves a direct activation of caspase-3 by large amounts of caspase-8 generated at the DISC (Type I cells). The other is related to the cleavage of Bid by low concentration of caspase-8, leading to the release of cytochrome c from mitochondria and the activation of caspase-3 by the cytochrome c/APAF-1/caspase-9 apoptosome (Type 11 cells). It is also known that the protein synthesis inhibitor cycloheximide (CHX) sensitizes Type I cells to CD95-mediated apoptosis, but it remains contradictory whether this effect also occurs in Type II cells. Here, we show that sub-lethal doses of CHX render both Type I and Type II cells sensitive to the apoptogenic effect of anti-CD95 antibodies but not to chemotherapeutic drugs. Moreover, Bcl-2-positive Type II cells become strongly sensitive to CD95-mediated apoptosis by the addition of CHX to the cell culture. This is not the result of a restraint of the anti-apoptotic effect of Bcl-2 at the mitochondrial level since CHX-treated Type II cells still retain their resistance to chemotherapeutic drugs. Therefore, CHX treatment is granting the CD95-mediated pathway the ability to bypass the mitochondria requirement to apoptosis, much alike to what is observed in Type I cells. (c) 2007 Elsevier Inc.

Bakgrund: Det finns begränsad kunskap om hur kvinnor upplever fosterrörelser i slutet av graviditeten. Ökad kunskap om fosterrörelser kan bidra till bättre möjligheter att identifiera foster som riskerar att dö intrauterint. Syfte: Att utforska hur gravida kvinnor upplever fosterrörelser i slutet av en okomplicerad graviditet samt hur mammor som mist ett barn i livmodern upplevt kontakten med barnet tiden före beskedet att barnet hade dött. Metod: Delstudie I, djupintervjuer med 26 mammor vars barn dött före födelsen, efter 28 fullgångna graviditetsveckor. Delstudie II, frågeformulär till 393 kvinnor med okomplicerad graviditet som besvarades i graviditetsvecka 37 till 42. Svaren analyserades i båda studierna med kvalitativ innehållsanalys. Resultat: 22 mammor i delstudie I beskrev att de hade haft en föraning om att något kunde ha hänt deras barn innan de fick besked att barnet dött intrauterint. Föraningen grundades på att mammorna hade upplevt minskade eller uteblivna fosterrörelser. Det är något som inte stämmer; formulerades som ett sammanfattande tema på mammornas föraning. Processen mot insikten om att deras barn dött beskrivs i olika steg; Inte känna kontakt med barnet; Känna oro; Känna att något är fel; Inte begripa det ofattbara; Vilja få besked; Vara säker på att barnet har dött. I delstudie II beskrev 383 (96 %) kvinnor i fullgången okomplicerad graviditet olika rörelser som klassificerades som kraftfulla rörelser. De flesta kvinnorna beskrev flera typer av rörelser, tio (4 %) kvinnor beskrev fosterrörelser som inte inkluderade någon rörelse i kategorin kraftfulla rörelser. Konklusion: Mammor som mist sitt barn före födelsen hade känt en föraning om att deras väntade barn kunde må dåligt, de hade upplevt att de tappat kontakten med barnet innan de fick besked att barnet hade dött i livmodern men normaliserade känslan. De flesta kvinnor med okomplicerad, fullgången graviditet, beskriver att barnet rör sig med kraft och tryck, få kvinnor beskriver rörelser som inte kan kategoriseras som kraftfulla. Implikationer: Blivande mammor bör uppmanas att lita på sin upplevelse av att det är något som inte stämmer och kontakta sjukvården direkt om de är bekymrade över sitt ofödda barns rörelser. Bedömning av fosterrörelser i fullgången graviditet kan inkludera: förekomst, frekvens och intensitet. Nyckelord: Innehållsanalys, fosterdöd, fosterrörelser, fullgången graviditet, upplevelser

Os vírus linfotrópicos de células T humanas do tipo I e II (HTLV-I/II) são retrovírus que podem ser transmitidos por transfusão de sangue. Estes vírus estão associados com paraparesia espástica tropical (PET), leucemia/linfoma de células T do adulto (L/LTA) e outras doenças sistêmicas imunomediadas. O presente estudo teve como objetivo investigar sinais clínicos de patologias associadas a esses vírus para utilizar na triagem clinica de candidatos à doação de sangue. Usou procedimentos padronizados para avaliação clinica de 30 doadores de sangue soropositivos para HTLV-I/II confirmados pela técnica de reação em cadeia da polimerase (PCR) matriculados no ambulatório do Núcleo de Medicina Tropical da UFPA. Paralelamente, através de interrogatório clínico complementar, estudou grupo controle com 40 candidatos à doação de sangue escolhidos aleatoriamente, que tiveram resultados sorológicos negativos. Dos 30 pacientes examinados, verificou-se que 23 eram portadores de HTLV-I e 07 HTLV-II. Na avaliação clínica, 15 pacientes (50%) não referiram queixas, sendo que 12 pacientes com queixas exclusivamente neurológicas. Observou 05 pacientes com formigamentos; 05 com diminuição da força muscular; 04 com constipação intestinal; 02 com parestesia; 02 com nódulos subcutâneos; 01 com incontinência urinária; 01 com visão borrada; 01 com diminuição do libido. No grupo controle, 05 candidatos (12,5%) referiram queixas. Os resultados indicam que diminuição da força muscular e formigamento devem ser questionados na triagem clínica prévia à doação de sangue para reduzir risco de infecção transfusional.

The purpose of this study is to make a 3-dimensional (3-D) evaluation of the pharyngeal airway space (PAS) in patients with class I, II, and III malocclusion. Sixty patients were evaluated. The patients were divided in 3 groups according to their occlusion classification. The volume and area of PAS were evaluated using the software Dolphin 3-D Imaging in the preoperative period for orthognathic surgery. PAS volume and area were influenced by different patterns of malocclusion. The mean volume and area for class III patients were statistically bigger than for classes I and II patients (P < .001). There was also a significant difference for volume values between class I and II patients, being the bigger volume for the class I patients (P < .05). It was possible to conclude that the class III patients presented a bigger PAS compared with classes I and II patients.

Objective: This study evaluated the variations in the anterior cranial base (S-N), posterior cranial base (S-Ba) and deflection of the cranial base (SNBa) among three different facial patterns (Pattern I, II and III). Method: A sample of 60 lateral cephalometric radiographs of Brazilian Caucasian patients, both genders, between 8 and 17 years of age was selected. The sample was divided into 3 groups (Pattern I, II and III) of 20 individuals each. The inclusion criteria for each group were the ANB angle, Wits appraisal and the facial profile angle (G’.Sn.Pg’). To compare the mean values obtained from (SNBa, S-N, S-Ba) each group measures, the ANOVA test and Scheffé’s Post-Hoc test were applied. Results and Conclusions: There was no statistically significant difference for the deflection angle of the cranial base among the different facial patterns (Patterns I, II and III). There was no significant difference for the measures of the anterior and posterior cranial base between the facial Patterns I and II. The mean values for S-Ba were lower in facial Pattern III with statistically significant difference. The mean values of S-N in the facial Pattern III were also reduced, but without showing statistically significant difference. This trend of lower values in the cranial base measurements would explain the maxillary deficiency and/or mandibular prognathism features that characterize the facial Pattern III.
