Abstract:

Summary The presence of Mithras in Regio VI, Umbria, is documented by materials (some inscriptions, two arae, two reliefs, two tauroctonies: one of them fragmentary, the other one almost complete) which were either fortuitously unearthed between the 18th and the 19th century without any further research following, or discovered during unsystematic excavations – in both cases, they ended up lost (or simply forgotten) among the other pieces of family collections. This is how Marquis Eroli and Count Valenti bought, respectively, a relief now kept at the Museo Archelogico in Terni and a fragmentary tauroctony, still visible today in the hall of his ancestral palace in Trevi; Count Ramelli retrieved a tauroctony and some inscriptions in Sentinum: the tauroctony was then walled in the hall of his palace in Fabriano and the inscriptions were collected in the lapidarium of the palace. Finally, Count Marignoli promoted the excavation of the Mithraeum in Spoleto, dug up by Fabio Gori and documented in drawings and watercolors by the architect Silvestri; currently that Mithraeum has been reduced to a shapeless heap of rubble and its materials are not to be found anywhere. This is definitely a distressing situation which, however, allows us to outline at least a Mithraic geography in Umbria made up of places along the Via Flaminia, east and west, where initiates to the Mithraic cult used to live, from Ocriculum to Interamna Nahars, Montoro, Spoletium, Trebiae, Carsulae and Sentinum, on the junction of the road coming from Helvillum. As for the cultores Mithrae in Regio VI, the few surviving inscriptions speak about them. There are freemen and freedmen, few slaves, some artisans, maybe some landowners or administrators of private and public estates who live and work at in-between towns and villae. They participate in the cult by covering various functions and supporting it financially: the leones in Carsulae collect money to build their leonteum; Sextus Egnatius Primitivus pays out of pocket to rebuild a spelaeum destroyed by an earthquake, while the thirty-five patroni of Sentinum contribute in different ways to the needs of their community.

Abstract:

Las consecuencias de la guerra de Sucesión española alejaron del Nuevo Mundo al emperador Carlos VI de Habsburgo. Tras los intentos infructuosos para movilizar redes políticas en los reinos de Indias, el Austria proyectó su poder al mundo ultramarino, no con una intervención armada directa, sino con la articulación de la Compañía de Ostende y la Privilegiada Compañía Oriental Imperial, con sedes en Viena y Trieste. A causa de la emulación de Gran Bretaña, las Provincias Unidas y las Dos Coronas borbónicas, el emperador remitió en 1723 un enviado extraordinario a Lisboa para lograr la cobertura de Juan V de Portugal a dichas empresas: Juan Jacinto Vázquez de Vargas, conde de Pinos Puente. A través de su misión –fracasada o pírrica– se conocerán los medios de negociación con las autoridades lusas, la rearticulación de redes comerciales regio-cesáreas imbricadas en las lógicas del comercio ultramarino luso y el impacto de las prácticas informales de la diplomacia a la hora de captar voluntades para los intereses de Carlos VI.

Abstract:

The seismic vulnerability of ancient free-standing multidrum stone columns is an important issue for the preservation of Greek and Roman archaeological sites. Such elements show a complex and highly non-linear dynamic behavior, requiring specific and sophisticated structural analysis. Different numerical studies on the dynamic behavior of ancient multidrum stone columns found that their seismic response is sensitive to their geometrical parameters, as well as to the material elastic properties, the kinetic coefficient of friction and the amplitude and frequency of the seismic action. Therefore, in the present research, a detailed survey of free-standing multidrum stone columns representative of a wide range of elements at the Pompeii Archaeological site was developed to provide a primary evaluation of the seismic vulnerability of such elements based on their geometrical properties. The study focuses on 103 multidrum grey-tuff columns, from four areas at the site: tetrastyle atrium of Casa del Fauno at Regio VI and Quadriportico dei Teatri, Foro Triangolare and Palestra Sannitica at Regio VIII. Grey tuff was a typically locally sourced natural stone, used as a building material in ancient Pompeii. The research areas included both private (Casa del Fauno) and public buildings (Quadriportico dei Teatri, Foro Triangolare and Palestra Sannitica). The mean overall geometrical properties affecting the seismic behavior of the columns in each research area and the discussion of the collected results are herein presented.

Abstract:

Se presenta la villa romana de Gaius Iulius Rufio, situada en la via Flaminia (Regio VI, Italia) y su evolución cronológica. El análisis de las fases del conjunto arquitectónico se basa en el estudio de los mosaicos y las curvas cronológicas realizadas a partir de la cuantificación cerámica. La villa fue construida en el último cuarto del siglo I a. C. como villa esclavista, presentando un ergastulum en la pars rustica (Fase 1). En la segunda mitad del siglo I d. C. se observa una fuerte remodelación del conjunto (Fase 2) con la amortización del ergastulum y la extensión de estructuras productivas en la pars urbana. Esta fase marcaría un límite máximo de extensión de los sistemas esclavistas en esta región que podría servir de referencia para el conjunto villas esclavistas romanas en Italia. A finales del siglo I d. C. o principios del siglo II d. C. el conjunto presenta potentes fases de destrucción y abandono.

Abstract:

Se pretende mostrar, a partir del análisis de la diplomática, el papel que posiblemente desarrolló la infanta Elvira Alfonso (hija natural del rey Alfonso VI) en el temprano establecimiento de los freires hospitalarios en los reinos de León y de Castilla, a comienzos del siglo XII. Se aspira encontrar la conexión entre el patrocinio dinástico de la Orden del Hospital y la promoción de la peregrinación a Santiago de Compostela. Elvira Alfonso participó en la Primera Cruzada y viajó hasta Jerusalén, hecho que debió darle una posición privilegiada para orientar a sus familiares regios hacia la consecución de tales políticas, una vez de vuelta a su tierra natal. A partir de este probable influjo de Elvira, se observa cómo las mujeres de la familia real leonesa – con atención a la reina Urraca I - impulsaron el patrocinio de la Orden Hospitalaria en tierras del norte ibérico, una labor continuada y profundizada por los monarcas que las sucedieron.

Abstract:

The object of study in this paper is four unpublished kilns excavated in 2012 at Montelabate (Perugia, Italy), in the framework of the Montelabate Project. The workshop, in use from the mid-first to the fifth century AD, which produced amphorae, coarseware and tile, offers an interesting model for the study of the economy of production in Regio VI (Umbria). The location of the workshop allows the exploration of wider issues such as connectivity, changes in local and regional markets, and continuity in the exploitation of natural resources: the site had a rich clay deposit and was surrounded by densely forested hills, whilst the flat fertile fields were suitable for agriculture and wine production; connectivity was ensured by the river Ventia, a tributary of the Tiber, and by an internal road that joined the Via Flaminia. The paper discusses the substantial number of failed flat-bottomed wine amphorae of the Spello type, discovered at Montelabate, that revealed a large-scale production with little standardization, as eight different local types were identified. The manufacturing complex provides new evidence for a production system that played an important role on a larger regional scale as well as in the local economic network, which continued until the fifth century AD.

Abstract:

A series of phenylsilsesquioxane-benzoate heptacopper complexes 1–3 were synthesized and characterized by X-ray crystallography. Two parallel routes of toluene spontaneous oxidation (into benzyl alcohol and benzoate) assisted the formation of the cagelike structure 1. A unique multi-ligation of copper ions (from (i) silsesquioxane, (ii) benzoate, (iii) benzyl alcohol, (iv) pyridine, (v) dimethyl-formamide and (vi) water ligands) was found in 1. Directed self-assembly using benzoic acid as a reactant afforded complexes 2–3 with the same main structural features as for 1, namely heptanuclear core coordinated by (i) two distorted pentameric cyclic silsesquioxane and (ii) four benzoate ligands, but featuring other solvate surroundings. Complex 3 was evaluated as a catalyst for the oxidation of alkanes to alkyl hydroperoxides and alcohols to ketones with hydrogen peroxide and tert-butyl hydroperoxide, respectively, at 50 °C in acetonitrile. The maximum yield of cyclohexane oxidation products as high as 32% was attained. The oxidation reaction results in a mixture of cyclohexyl hydroperoxide, cyclohexanol, and cyclohexanone. Upon the addition of triphenylphosphine, the cyclohexyl hydroperoxide is completely converted to cyclohexanol. The specific regio- and chemoselectivity in the oxidation of n-heptane and methylcyclohexane, respectively, indicate the involvement of of hydroxyl radicals. Complex 3 exhibits a high activity in the oxidation of alcohols.

Abstract:

Recently, Kehlmaier & Assmann (2008) presented a revision of the European representatives of the big-headed fly genus Chalarus Walker, 1834. The work introduced four previously unknown taxa and provided diagnoses of all other known species, illustrated through numerous line drawings and photo-micrographs. In total, the authors treated 25 species including one nomen dubium. Three of these were known from males only and five solely from females. Taxonomic decision-making was backed up by molecular evidence, published partly therein and in the context of a phylogenetic study of the subfamily Chalarinae (Kehlmaier & Assmann 2010). Despite large collecting efforts, three taxa could not be analysed genetically, namely C. argenteus Coe, 1966, C. elegantulus Jervis, 1992 and C. proprius Jervis, 1992, all representing species based on females only. Shortly after the publication of the above mentioned revision, a specimen of C. elegantulus was identified amongst material sent by Dr. Gunilla Ståhls (Finnish Museum of Natural History, Helsinki): 1&, Finland, Ab (Regio aboënsis), Karjalohja, Karkalinniemi, 66581:33221, control trap #2, 25.VI.–22.VII.2007, leg. G. Ståhls, coll. C. Kehlmaier. The 5’ half of the mitochondrial cytochrome oxidase subunit 1 (CO1) gene was sequenced following standard lab procedures (see Kehlmaier & Assmann 2010) using the primer pair LCO1490 and HCO2198 (Folmer et al. 1994). The resulting DNA-barcode (Genbank sequence accession number: FN999909) was compared against a set of reference Chalarus barcode sequences and matched C. absconditus Kehlmaier in Kehlmaier & Assmann, 2008 syn. nov., a species know from male specimens only, sharing an identical haplotype.

Abstract:

V. Kockel has discussed the model as one of the few surviving examples of a form of three-dimensional archaeological recording that was developed by the Padiglione family and other model-makers for the King of the Two Sicilies. Here I provide comparisons with the extant remains of the house, to illustrate how much more we can learn from the model of specific details of the structure and decoration that have been lost since 1840, when the building was still in a remarkably better state of preservation. Aside from the inevitable gradual deterioration of wall-paintings and pavements, which remained almost completely open to the elements after the original excavation was completed in 1809, a direct hit by a bomb on September 23, 1943, left the SE corner a mound of overgrown ruins. In 1970-72, when the Soprintendenza completely roofed the main house block, cleared the bomb rubble, and added low modern walls along the lines of the destroyed rooms to give tourists some idea of the original plan, I directed 37 soundings below the level of A.D. 79. Then between 2005 and 2007, as part of the Progetto Regio VI under F. Coarelli and F. Pesando, M. Stella and I added 17 more soundings, mainly in the area of the peristyle and on the S side of the house. Our final study of the house provided a detailed analysis of its original excavation during the Napoleonic Wars, a full description of the extant rooms and building history, and reports on our excavations.

Abstract:

From the moment of Luther’s defiance of both Pope and Emperor at the Diet of Worms the sixteenth century became a period par excellence of cuius regio, eius religio, and of nowhere was this more true than for the very different societies of England and Poland. In England, for that time a highly centralized country, the nation’s religious fate oscillated wildly with the change of monarchs and their respective governments, mildly reformist under Henry VIII so long as Thomas Cromwell held power, indisputedly Protestant during the rule of the boy king, Edward VI, as indisputedly Roman Catholic in the equally short reign of Mary I, and then Protestant, as it turned out permanently, on the accession of Elizabeth. In Poland, where, because of its proximity to Wittenberg, Luther’s teachings began taking root at least within the German communities considerably earlier than in England, the spread first of Lutheranism and then Calvinism depended far more on the attitude of the nobility than of the monarch, though the succession of the more tolerant Sigismund Augustus in 1548 certainly accelerated the process. Apart from the five years between 1547 and 1553 in England, in neither country was life easy for converts to the Swiss version of Protestantism before 1560, and at different times both Polish and English Protestants suffered quite severe episodes of persecution: this essay traces the fortunes of the Poles who found a refuge in England and of the English who sought a temporary haven in Poland on account of their religion in the mid-sixteenth century.

Abstract:

Immunolocalization studies demonstrate that Type VI collagen forms a flexible network that interweaves among collagen fibrils in the dermis of skin as well as in other loose connective tissues. Although binding of Type VI collagen with other matrix components has been suggested, no structural evidence supporting these studies has been reported. In this study, we demonstrate that Type VI microfilaments consistently cross-banded collagen fibrils near the “d” band, indicating that the interaction of Type VI collagen with banded fibrils is not passive. This “d” band is also the location of the binding domain of decorin to banded fibrils, suggesting that decorin mediates the interaction of Type VI microfilaments with banded fibers. Examination of the architecture of the Type VI network in a decorin nullizygous mouse demonstrates a continuance of this specific interaction, indicating that the association is not entirely dependent on the presence of decorin. At least one other component, whose identity is uncertain, persists near the “d” band, which may also serve to mediate the attachment of Type VI collagen to collagen fibrils.

Abstract:

Contexte : Le variant Kappa est désigné comme un variant d’intérêt (VI) du coronavirus du syndrome respiratoire aigu sévère 2 (SRAS-CoV-2). Nous avons recensé 195 cas du variant Kappa dans une région de la Colombie-Britannique, au Canada, le plus grand agrégat spatio-temporel publié en Amérique du Nord. Objectifs : Décrire l’épidémiologie du variant Kappa en relation avec d’autres variants préoccupants (VP) du SRAS-CoV-2 en circulation dans la région afin de déterminer si l’épidémiologie du variant Kappa demande un statut de VI ou de VP. Méthodes : Les échantillons cliniques qui se sont avérés positifs pour le SRAS-CoV-2 collectés entre le 10 mars et le 2 mai 2021 ont été examinés pour la détection des VP circulants connus; environ 50 % des échantillons ont ensuite été sélectionnés pour le séquençage du génome entier. Une analyse épidémiologique a été réalisée en comparant les caractéristiques des cas Kappa aux principaux variants circulant dans la région (Alpha et Gamma) et aux cas non VP/VI. Résultats : Au total, 2 079 cas de maladie à coronavirus 2019 (COVID-19) ont été signalés dans la région pendant la période d’étude, dont 54 % ont été sélectionnés pour le séquençage du génome entier. Les 1 131 cas séquencés ont été classés en Kappa, Alpha, Gamma et non VP/VI. Alors que les cas Alpha et Gamma se sont avérés avoir un taux d’attaque significativement plus élevé parmi les contacts familiaux par rapport aux cas non VI/VP, ce n’était pas le cas pour le variant Kappa. Conclusion : L’analyse épidémiologique soutient la désignation du variant Kappa comme un VI et non un VP. Les variants Alpha et Gamma se sont avérés plus transmissibles, ce qui explique leur domination ultérieure dans la région et la disparition rapide du variant Kappa. Les stratégies de surveillance des variants doivent mettre l’accent à la fois sur la détection des VP établis et sur la détection de nouveaux VP potentiels.

Abstract:

AbstractIn this study, selected heavy metals resistant heterotrophic bacteria isolated from soil samples at the Windmill Islands region, Wilkes Land (East Antarctica), were characterized. Phylogenetic analysis revealed affiliation of isolates to genera Bacillus, Lysinibacillus, Micrococcus and Stenotrophomonas. The strains were found to be psychrotolerant and halotolerant, able to tolerate up to 10% NaCl in the growth medium. The Minimum Inhibitory Concentration of the seven heavy metals Cr, Cu, Ni, Co, Cd, Zn, and Pb was determined in solid media for each bacterial strain. Gram−positive Vi−2 strain and Gram−negative Vi−4 strain showed highest multiply heavy metals resistance, and Vi−3 and Vi−4 strains showed multi−antibiotic resistance to more than a half of the 13 used antibiotics. Plasmids were detected only in Gram−negative Vi−4 strain. The bacteria were able to produce different hydrolytic enzymes including industrially important proteases, xylanases, cellulases, and β−glucosidases. High heavy metals resistance of the Antarctic bacteria suggests their potential application for wastewater treatment in cold and temperate climates. Highly sensitive to Cd and Co ions Vi−1, Vi−5 and Vi−7 strains would be promising for developing biosensors to detect these most toxic heavy metals in environmental samples.

Abstract:

Myosin VI is a reverse-direction molecular motor implicated in membrane transport events. Because myosin VI is most highly expressed in the kidney, we investigated its renal localization by using high-resolution immunocytochemical and biochemical methods. Indirect immunofluorescence microscopy revealed myosin VI at the base of the brush border in proximal tubule cells. Horseradish peroxidase uptake studies, which labeled endosomes, and double staining for clathrin adapter protein-2 showed that myosin VI was closely associated with the intermicrovillar (IMV) coated-pit region of the brush border. Localization of myosin VI to the IMV region was confirmed at the electron microscopic level by colloidal gold labeling of ultrathin cryosections. In addition, antigen retrieval demonstrated a small but significant pool of myosin VI on the microvilli. To confirm the association of myosin VI with the IMV compartment, these membranes were separated from other membrane compartments by using 15–25% OptiPrep density gradients. Immunoblotting of the gradient fractions confirmed that myosin VI was enriched with markers for the IMV microdomain of the brush border, suggesting that myosin VI associates with proteins in this compartment. Finally, we examined the expression of myosin VI during nephron development. We found myosin VI present in a diffuse cytoplasmic pattern at stage II (S-shaped body phase) and that it was only redistributed fully to the brush border in the stage IV nephron. These studies support a model for myosin VI function in the endocytic process of the proximal tubule.

Abstract:

Given a set of points P = {p1, p2, …, pn} in the Euclidean plane, with each point piassociated with a given direction vi∈ V. P(pi, vi) defines a half-plane and L(pi, vi) denotes the baseline that is perpendicular to viand passing through pi. Define a region dominated by piand vias a Baseline Bounded Half-Plane Voronoi Region, denoted as V or(pi, vi), if a point x ∈ V or(pi, vi), then (1) x ∈ P(pi, vi); (2) the line segment l(x, pi) does not cross any baseline; (3) if there is a point pj, such that x ∈ P(pj, vj), and the line segment l(x, pj) does not cross any baseline then d(x, pi) ≤ d(x, pj), j ≠ i. The Baseline Bounded Half-Plane Voronoi Diagram, denoted as V or(P, V), is the union of all V or(pi, vi). We show that V or(pi, vi) and V or(P, V) can be computed in O(n log n) and O(n2log n) time, respectively. For the heterogeneous point set, the same problem is also considered.

Abstract:

Background: It remains unknown whether access to elite blind sports opportunities is globally balanced or matches the prevalence of blindness/visual impairment (VI). The primary objective of this study was to determine the rate of elite blind sports participation in each world region registered in the International Blind Sports Federation’s (IBSA) and to assess its association with the global and regional prevalence of blindness/VI. The secondary objective was to determine the association between other covariates, such as age, vision class, and sex, with the number of IBSA-registered athletes from each region. Methods: A baseline estimate of blindness/VI data was established and used when comparing participation rates to blindness/VI rates. Descriptive statistics were used to describe sports participation and associated co-variates. Results: Among 123 member countries registered in IBSA, 31 did not have any completed registrations in blind sports, of which 22 had a prevalence of blindness/VI higher than the global average. During the summer season 2019, 738 (29.52%) IBSA athletes were female and 1762 (70.48%) were male. Conclusions: These results suggest elite blind/VI sport participation is limited independently from blindness/VI prevalence. Increasing blind-friendly sport resources, especially in low-and-middle-income countries (LMICs), would improve the rate of elite sport participation among athletes with blindness/VI.

Abstract:

Abstract The availability of numerous antisera prepared against lambda-type Bence Jones proteins and lambda chains of known amino acid sequence has led to the differentiation and classification of human lambda light chains into one of five V lambda subgroups. The five serologically defined subgroups, V lambda I, V lambda II, V lambda III, V lambda IV, and V lambda VI, correspond to the chemical classification that is based on sequence homologies in the first framework region (FR1). Proteins designated by sequence as lambda V react with specific anti-lambda II antisera and are thus included in the V lambda II subgroup classification. The isotypic nature of the five V lambda subgroups was evidenced through analyses of lambda-type light chains that were isolated from the IgG of normal individuals. Based on analyses of 116 Bence Jones proteins, the frequency of distribution of the lambda I, lambda II/V, lambda III, lambda IV, and lambda VI proteins in the normal lambda chain population is estimated to be 27%, 37%, 23%, 3%, and 10%, respectively. This distribution of V lambda subgroups was comparable to that found among 82 monoclonal Ig lambda proteins. Considerable V lambda intragroup antigenic heterogeneity was also apparent. At least two sub-subgroups were identified among each of the five major V lambda subgroups, implying the existence of multiple genes in the human V lambda genome. The V lambda classification of 54 Ig lambda proteins obtained from patients with primary or multiple myeloma-associated amyloidosis substantiated the preferential association of lambda VI light chains with amyloidosis AL and the predominance of the normally rare V lambda VI subgroup in this disease.

Abstract:

Aims. The observational constraints on the baryon content of the warm-hot intergalactic medium (WHIM) rely almost entirely on far ultraviolet (FUV) measurements. However, cosmological, hydrodynamical simulations predict strong correlations between the spatial distributions of FUV and X-ray absorbing WHIM. We investigate this prediction by analyzing XMM-Newton X-ray counterparts of FUV-detected intergalactic O VI absorbers known from FUSE and HST/STIS data, thereby aiming to gain understanding on the properties of the hot component of FUV absorbers and to compare this information to the predictions of simulations. Methods. We study the X-ray absorption at the redshift of the only significantly detected O VI absorber in the Ton S 180 sightline’s FUV spectrum, found at zOVI = 0.04579 ± 0.00001. We characterize the spectral properties of the O VI-O VIII absorbers and explore the ionization processes behind the measured absorption. The observational results are compared to the predicted warm-hot gas properties in the EAGLE simulation to infer the physical conditions of the absorber. Results. We detect both O VI and O VII absorption at a 5σ confidence level, whereas O VIII absorption is not significantly detected. Collisional ionization equilibrium (CIE) modeling constrains the X-ray absorbing gas temperature to log TCIE (K) = 6.22 ± 0.05 with a total hydrogen column density NH = 5.8−2.2+3.0 × Z⊙/Zabs × 1019 cm−2. This model predicts an O VI column density consistent with that measured in the FUV, but our limits on the O VI line width indicate > 90% likelihood that the FUV-detected O VI arises from a different, cooler phase. We find that the observed absorber lies about a factor of two further away from the detected galaxies than is the case for similar systems in EAGLE Conclusions. The analysis suggests that the detected O VI and O VII trace two different – warm and hot – gas phases of the absorbing structure at z ≈ 0.046, of which the hot component is likely in collisional ionization equilibrium. As the baryon content information of the studied absorber is primarily imprinted in the X-ray band, understanding the abundance of similar systems helps to define the landscape for WHIM searches with future X-ray telescopes. Our results highlight the crucial role of line widths for the interpretation and detectability of WHIM absorbers.

Abstract:

AbstractVi capsular polysaccharide (Vi antigen) was first identified as the virulence antigen of Salmonella enterica serovar Typhi (S. Typhi), the causative agent of typhoid fever in humans. The presence of Vi antigen differentiates S. Typhi from other serovars of Salmonella. Vi antigen is a linear polymer consisting of α-1,4-linked-N-acetyl-galactosaminuronate, whose expression is controlled by three chromosomal loci, namely viaA, viaB and ompB. Both viaA and viaB region are present on Salmonella Pathogenicity Island-7, a large, mosaic, genetic island. The viaA region encodes a positive regulator and the viaB locus is composed of 11 genes designated tviA-tviE (for Vi biosyhthesis), vexA-vexE (for Vi antigen export) and ORF 11. Vi polysaccharide is synthesized from UDP-N-acetyl glucosamine in a series of steps requiring TviB, TviC, and TviE, and regulation of Vi polysaccharide synthesis is controlled by two regulatory systems, rscB-rscC (viaA locus) and ompR-envZ (ompB locus), which respond to changes in osmolarity. This antigen is highly immunogenic and has been used for the formulation of one of the currently available vaccines against typhoid. Despite advancement in the area of vaccinology, its pace of progress needs to be accelerated and effective control programmes will be needed for proper disease management.

Abstract:

ABSTRACT Herpes simplex virus type 1 (HSV-1) DNA polymerase contains several conserved regions within the polymerase domain. The conserved regions I, II, III, V, and VII have been shown to have functional roles in the interaction with deoxynucleoside triphosphates (dNTPs) and DNA. However, the role of conserved region VI in DNA replication has remained unclear due, in part, to the lack of a well-characterized region VI mutant. In this report, recombinant viruses containing a point mutation (L774F) within the conserved region VI were constructed. These recombinant viruses were more susceptible to aphidicolin and resistant to both foscarnet and acyclovir, compared to the wild-type KOS strain. Marker transfer experiments demonstrated that the L774F mutation conferred the altered drug sensitivities. Furthermore, mutagenesis assays demonstrated that L774F recombinant viruses containing the supF marker gene, which was integrated within the thymidine kinase locus (tk), exhibited increased fidelity of DNA replication. These data indicate that conserved region VI, together with other conserved regions, forms the polymerase active site, has a role in the interaction with deoxyribonucleotides, and regulates DNA replication fidelity. The possible effect of the L774F mutation in altering the polymerase structure and activity is discussed.

Meng, I. D., J. W. Hu, A. P. Benetti, and D. A. Bereiter. Encoding of corneal input in two distinct regions of the spinal trigeminal nucleus in the rat: cutaneous receptive field properties, responses to thermal and chemical stimulation, modulation by diffuse noxious inhibitory controls, and projections to the parabrachial area. J. Neurophysiol. 77: 43–56, 1997. To determine whether corneal input is processed similarly at rostral and caudal levels of the spinal trigeminal nucleus, the response properties of second-order neurons at the transition between trigeminal subnucleus interpolaris and subnucleus caudalis (Vi/Vc) and at the transition between subnucleus caudalis and the cervical spinal cord (Vc/C1) were compared. Extracellular single units were recorded in 68 Sprague-Dawley rats under chloralose or urethan/chloralose anesthesia. Neurons that responded to electrical stimulation of the cornea at the Vi/Vc transition region ( n = 61) and at laminae I/II of the Vc/C1 transition region ( n = 33) were classified regarding 1) corneal mechanical threshold; 2) cutaneous mechanoreceptive field, if present; 3) electrical input characteristics (A and/or C fiber); 4) response to thermal stimulation; 5) response to the small-fiber excitant, mustard oil (MO), applied to the cornea; 6) diffuse noxious inhibitory controls (DNIC); and 7) projection status to the contralateral parabrachial area (PBA). On the basis of cutaneous receptive field properties, neurons were classified as low-threshold mechanoreceptive (LTM), wide dynamic range (WDR), nociceptive specific (NS), or deep nociceptive (D). All neurons recorded at the Vc/C1 transition region were either WDR ( n = 19) or NS ( n = 14). In contrast, 54% of the Vi/Vc neurons had no cutaneous receptive field. Of those Vi/Vc neurons that had a cutaneous receptive field, 57% were LTM, 25% were WDR, and 18% were D. All Vc/C1 neurons responded to noxious thermal and MO stimulation. Only 22 of 47 and 13 of 19 Vi/Vc corneal units responded to thermal or MO stimulation, respectively. At the Vc/C1 transition region, 12 of 17 neurons demonstrated DNIC, whereas at the Vi/Vc transition region, DNIC was present in only 4 of 26 neurons. Of 15 Vc/C1 corneal units, 12 could be antidromically activated from the contralateral PBA (average latency 6.29 ms, range 1.8–26 ms). None of 22 Vi/Vc corneal units tested could be antidromically activated from the PBA. These findings suggest that neurons in laminae I/II at the Vc/C1 transition and at the Vi/Vc transition process corneal input differently. Neurons in laminae I/II at the Vc/C1 transition process corneal afferent input consistent with that from other orofacial regions. Corneal-responsive neurons at the Vi/Vc transition region may be important in motor reflexes or in recruitment of descending antinociceptive controls.

Abstract:

Myosin VI plays important roles in endocytic and exocytic membrane-trafficking pathways in cells. Because recent work has highlighted the importance of targeted membrane transport during cytokinesis, we investigated whether myosin VI plays a role in this process during cell division. In dividing cells, myosin VI undergoes dramatic changes in localization: in prophase, myosin VI is recruited to the spindle poles; and in cytokinesis, myosin VI is targeted to the walls of the ingressing cleavage furrow, with a dramatic concentration in the midbody region. Furthermore, myosin VI is present on vesicles moving into and out of the cytoplasmic bridge connecting the two daughter cells. Inhibition of myosin VI activity by small interfering RNA (siRNA)-mediated knockdown or by overexpression of dominant-negative myosin VI tail leads to a delay in metaphase progression and a defect in cytokinesis. GAIP-interacting protein COOH terminus (GIPC), a myosin VI binding partner, is associated with the function(s) of myosin VI in dividing cells. Loss of GIPC in siRNA knockdown cells results in a more than fourfold increase in the number of multinucleated cells. Our results suggest that myosin VI has novel functions in mitosis and that it plays an essential role in targeted membrane transport during cytokinesis.

Abstract:

We identified a novel interaction between myosin VI and the GLUT1 transporter binding protein GLUT1CBP(GIPC1) and first proposed that as an adapter molecule it might function to couple vesicle-bound proteins to myosin VI movement. This study refines the model by identifying two myosin VI binding domains in the GIPC1 C terminus, assigning respective oligomerization and myosin VI binding functions to separate N- and C-terminal domains, and defining a central region in the myosin VI tail that binds GIPC1. Data further supporting the model demonstrate that 1) myosin VI and GIPC1 interactions do not require a mediating protein; 2) the myosin VI binding domain in GIPC1 is necessary for intracellular interactions of GIPC1 with myosin VI and recruitment of overexpressed myosin VI to membrane structures, but not for the association of GIPC1 with such structures; 3) GIPC1/myosin VI complexes coordinately move within cellular extensions of the cell in an actin-dependent and microtubule-independent manner; and 4) blocking either GIPC1 interactions with myosin VI or GLUT1 interactions with GIPC1 disrupts normal GLUT1 trafficking in polarized epithelial cells, leading to a reduction in the level of GLUT1 in the plasma membrane and concomitant accumulation in internal membrane structures.

Abstract:

Premature human mortality due to cardiopulmonary disease and lung cancer is found in epidemiological studies to be correlated to increased levels of atmospheric particulate matter. Such negative dust effects on the human mortality in the North Africa - Europe - Middle East region can be successfully studied by the DREAM dust model. However, to assess health effects of dust and its other impacts on the environment, a detailed modelling of the climate for a period of one year in a high-resolution mode is required. We describe here a parallel implementation of the DREAM dust model, the DREAMCLIMATE service, which is optimised for use on the high-performance regional infrastructure provided by the VI-SEEM project. In addition to development and integration of this service, we also present a use-case study of premature mortality due to desert dust in the North Africa - Europe - Middle East region for the year 2005, to demonstrate how the newly deployed service can be used.

Abstract:

Immunolocalizaton studies of type VI collagen in skin have previously demonstrated that type VI collagen forms a flexible network that anchors large interstitial structures such as nerves, blood vessels, and collagen fibers into the surrounding connective tissues matrix. The purpose of this study is to determine if individual type VI collagen microfilaments might be connected to banded collagen fibrils, thereby stabilizing the network.Solid phase binding assays suggest a specific, high affinity interaction between the core protein of the dermatan sulfate proteoglycan decorin and type VI collagen, and immunocytochemical studies in fetal and neonate rabbit cornea suggest an association of decorin with type VI microfilaments. Other studies in skin and perichondrium have localized decorin to a region between the d and e bands of banded collagen fibrils. However, no direct documentation has demonstrated a specific structural interaction between type VI microfilaments and banded collagen fibrils. We, therefore, sought to determine if type VI microfilaments cross banded collagen fibrils between the “d” and “e” bands.

Abstract:

The most fundamental purpose of infrared (IR) and visible (VI) image fusion is to integrate the useful information and produce a new image which has higher reliability and understandability for human or computer vision. In order to better preserve the interesting region and its corresponding detail information, a novel multiscale fusion scheme based on interesting region detection is proposed in this paper. Firstly, the MeanShift is used to detect the interesting region with the salient objects and the background region of IR and VI. Then the interesting regions are processed by the guided filter. Next, the nonsubsampled contourlet transform (NSCT) is used for background region decomposition of IR and VI to get a low-frequency and a series of high-frequency layers. An improved weighted average method based on per-pixel weighted average is used to fuse the low-frequency layer. The pulse-coupled neural network (PCNN) is used to fuse each high-frequency layer. Finally, the fused image is obtained by fusing the fused interesting region and the fused background region. Experimental results demonstrate that the proposed algorithm can integrate more background details as well as highlight the interesting region with the salient objects, which is superior to the conventional methods in objective quality evaluations and visual inspection.

Abstract:

Corneal nociceptors terminate at the trigeminal subnucleus interpolaris/caudalis (Vi/Vc) transition and subnucleus caudalis/upper cervical spinal cord (Vc/C1) junction regions of the lower brain stem. The aims of this study were to determine if local GABAA receptor activation modifies corneal input to second-order neurons at these regions and if GABAA receptor activation in one region affects corneal input to the other region. In barbiturate-anesthetized male rats, corneal nociceptors were excited by pulses of CO2 gas, and GABAA receptors were activated by microinjections of the selective agonist muscimol. Local muscimol injection at the site of recording inhibited all Vi/Vc and Vc/C1 units tested and was reversed partially by bicuculline. To test for ascending intersubnuclear communication, muscimol injection into the caudal Vc/C1 junction, remote from the recording site at the Vi/Vc transition, inhibited the evoked response of most corneal units, although some neurons were enhanced. Injection of the nonselective synaptic blocking agent, CoCl2, remotely into the Vc/C1 region inhibited the evoked response of all Vi/Vc units tested. To test for descending intersubnuclear communication, muscimol was injected remotely into the rostral Vi/Vc transition and enhanced the evoked activity of all corneal units tested at the caudal Vc/C1 junction. These results suggest that GABAA receptor mechanisms play a significant role in corneal nociceptive processing by second-order trigeminal brain stem neurons. GABAA receptor mechanisms act locally at both the Vi/Vc transition and Vc/C1 junction regions to inhibit corneal input and act through polysynaptic pathways to modify corneal input at multiple levels of the trigeminal brain stem complex.

Abstract:

The past 3 years since the last solar maximum have witnessed an unprecedented number (>200) of published scientific papers on many aspects of solar radiophysics. These contributions are the result of an intense research effort mounted during the first Solar Maximum Mission of 1980 and continued until the present. Excellent x-ray, EUV, and visible light observations of the disturbed corona and transition region have been obtained from the SMM, Hinotori, P78-1, and ISEE-3 spacecraft. ISEE-3 also has provided very low-frequency radio observations of solar bursts in the interplanetary medium. Ground-based radio support for space experiments has been provided by many observatories throughout the world. In particular, many collaborative studies using x-ray and radio observations of solar flares have been reported. The outstanding radio instrument during this period has been the VLA, operating at 2, 6, and 20 cm with a time resolution of 10 s and both modes of circular polarization. The two-dimensional spatial resolution of the radio images is a few seconds of arc, almost as good as the best resolution obtained so far at any wavelength in the solar spectrum. To complement the rather poor time resolution of the VLA one-dimensional arrays such as the WSRT at 6 cm wavelength and the Nobeyama interferometer at 17 GHz have been used successfully. In addition, a number of very-high-time resolution radiometers have been built at different locations. At meter wavelengths two-dimensional arrays at Clark Lake, Culgoora, and Nancay and a one-dimensional array at Nobeyama have been employed. The little known region of the solar spectrum at decimeter wavelengths is being investigated by the Zurich spectrograph. It is pleasing to see Chinese participation in solar radiophysics.

Reductive adsorption of chromium (Cr) has been investigated, employing coal-based activated carbon with batchwise study. The adsorption was carried out by varying parameters such as pH of the aqueous solution and contact time. Cr(III) was hardly adsorbed on activated carbon, and it was precipitated at high pH region. High adsorption amounts of Cr(VI) was obtained at pH range 4.5 – 5.5. In the adsorption process, reduction of Cr(VI) to Cr(III) was occurred at especially acidic pH region, and thus most of Cr remained in the aqueous solution in this pH region was Cr(III).

Abstract:

ABSTRACTThe study the diet of Eneolithic populations is of great interest to archaeologists. However, the studies undertaken in the steppe and forest-steppe zones of Volga region in Russia have left many issues unsolved. Data collected recently through the comprehensive studies of Lebyazhinka VI settlement enable us to change this situation. Of particular importance at this settlement site is good preservation of animal bones, bone fishing tools, and ceramics of the same type with food crusts and connected to a large house pit. For the first time in this geographical area, bones of domestic animals were found in the fill of a dwelling. The aim of this paper is to present the results obtained through comprehensive studies of diet and economy in the Eneolithic based on the materials from Lebyazhinka III and Lebyazhinka VI settlement sites. The main results of the archaeozoological analysis— determinations of species, age and size of the animals—provide the necessary data for studying the diet. We conclude that there are differences between Lebyazhinka III and Lebyazhinka VI settlements. Lebyazhinka III settlement included bones of only wild species, however, Lebyazhinka VI settlement consists of wild and domestic species.

Abstract:

Microbial Cr(VI) reduction in groundwater aquifer media was investigated in microcosm reactors extracted from Cr(VI) contaminated sites in South Africa. The reactors were operated under an influent Cr(VI) concentration of 40 mg/L to simulate the current Cr(VI) level at the contaminated site. Near complete Cr(VI) removal was observed in microcosm reactors inoculated with Cr(VI) reducing bacteria from dried activated sludge collected from a treatment plant receiving periodic loadings of Cr(VI). The best performance was observed under low hydraulic loading (flow rate, Q=0.310 cm3/hr). Microbial culture characterisation results showed a change in culture composition after 17 days of reactor operation, indicating Bacillus and Lysinibacillus species as the most dominant organisms in reactors that reduced Cr(VI). The predominance of Bacillus and Lysinibacillus species was either due to resilience against toxicity or adaptation to the changing conditions in the reactor. This research was the initial step towards the development of an in situ bioremediation process to contain the spread of a Cr(VI) plume in a groundwater aquifer at contaminated site in Brits, South Africa. South Africa holds about 72% percent of the world’s chromium resources, the majority of which is mined in the North Eastern region of the country formally known as Transvaal.

Abstract:

Filaments and fibrils that exhibit a 100-nm axial periodicity and occur in the medium and in the deposited extracellular matrix of chicken embryo and human fibroblast cultures have been tentatively identified with type VI collagen on the basis of their similar structural characteristics (Bruns, R. R., 1984, J. Ultrastruct. Res., 89:136-145). Using indirect immunoelectron microscopy and specific monoclonal and polyclonal antibodies, we now report their positive identification with collagen VI and their distribution in fibroblast cultures and in tendon. Primary human foreskin fibroblast cultures, labeled with anti-type VI antibody and studied by fluorescence microscopy, showed a progressive increase in labeling and changes in distribution with time up to 8 d in culture. With immunoelectron microscopy and monoclonal antibodies to human type VI collagen followed by goat anti-mouse IgG coupled to colloidal gold, they showed in thin sections specific 100-nm periodic labeling on extracellular filaments and fibrils: one monoclonal antibody (3C4) attached to the band region and another (4B10) to the interband region of the filaments and fibrils. Rabbit antiserum to type VI collagen also localized on the band region, but the staining was less well defined. Control experiments with antibodies to fibronectin and to procollagen types I and III labeled other filaments and fibrils, but not those with a 100-nm period. Heavy metal-stained fibrils with the same periodic and structural characteristics also have been found in both adult rat tail tendon and embryonic chicken tendon subjected to prolonged incubation in culture medium or treatment with adenosine 5'-triphosphate at pH 4.6. We conclude that the 100-nm periodic filaments and fibrils represent the native aggregate form of type VI collagen. It is likely that banded fibrils of the same periodicity and appearance, reported by many observers over the years in a wide range of normal and pathological tissues, are at least in part, type VI collagen.

Abstract:

ObjectivesTo establish the prevalence of self-reported vision impairment (VI) in Southwest Cameroon and describe associated care-seeking practices, functional limitations and economic hardships.DesignA three-stage clustered sampling household community-based survey.SettingThe Southwest region of Cameroon.Participants8046 individuals of all ages residing in the Southwest region of Cameroon.Primary and secondary outcome measuresPrevalence of self-reported VI, onset of vision loss, care-seeking practices, diagnosis and treatment, functional limitations, economic hardships on household, beliefs about surgical treatability of blindness and barriers to surgical care.ResultsThe estimated prevalence of self-reported VI in Southwest Cameroon was 0.87% (95% CI 0.62 to 1.21). Among participants aged ≥40 years, the prevalence increased to 2.61% (95% CI 1.74 to 3.90). Less than a quarter of affected participants reported difficulty working (20.5%) or trouble going to school (12.0%) as a result of their VI. Yet, over half (52%, n=43) of affected households experienced significant economic hardships due to the VI. Residing in an urban setting (aOR 1.16, 95% CI 1.04 to 1.30) and belonging to a higher socioeconomic status (aOR 1.13, 95% CI 1.02 to 1.26) were factors associated with the belief that certain types of blindness were surgically reversible. Formal care was not sought by 16.3% (n=8) of affected participants. Cataracts was the leading diagnosis among participants who did seek formal care (43.2%, n=16), although 93.8% of these cases were not surgically treated, primarily due to a lack of perceived need.ConclusionThe prevalence of individuals who report vision impairment in Southwest Cameroon is considerably lower than prior published estimates based on visual physical examinations. Routine community-level screening and cost financing schemes could improve detection of pre-clinical eye disease and the utilisation of surgical care. It could also pre-empt disability and economic hardships associated with advanced VI in the region.
