Abstract (sommario):
Prototypical class switching in mouse and human immunoglobulin heavy chains occurs through recombination of tandem blocks of short repeats located 5' to each heavy chain constant region (CH) except C delta. Deletion of C mu in immunoglobulin D (IgD)-secreting murine plasmacytomas occurs illegitimately. We demonstrate here that in human IgD-secreting myeloma cells freshly isolated from patient bone marrow and in normal peripheral blood B lymphocytes, an IgD switch can occur through homologous recombination of a direct repeat consisting of a 442-bp sequence 1.5 kbp 3' of the JH complex and a 443-bp sequence that is duplicated almost perfectly (96% similarity) 1.7 kbp 5' of the C delta gene (442/443-base-pair [bp] repeat). This homologous recombination mechanism is not exclusive for IgD switching, since C mu deletion endpoints in two established IgD-secreting myeloma cell lines fall outside the 442/443-bp repeat. The 442/443-bp mediated recombination shows cell type specificity, and we propose that it represents a unique mode for increased levels of IgD secretion in humans.

Abstract (sommario):
The title compound, C40H16O4or [C10H4O]4, is a planar tetrameric cyclooligomer which crystallizes in the monoclinic space groupP21/n. The compound is located on an inversion center with the asymmetric unit consisting of half of the molecule. The compound displays an interesting packing structure, where the cyclooligomer displays both layered packing with respect to nearest neighbors and a rotation of adjacent planar rings that results in additional interactions. The geometric parameters of the compound agree well with those of comparable cyclooligomers, while the packing reveals some similarities and differences.

Abstract (sommario):
Abstract This paper reviews the development of the ensemble Kalman filter (EnKF) for atmospheric data assimilation. Particular attention is devoted to recent advances and current challenges. The distinguishing properties of three well-established variations of the EnKF algorithm are first discussed. Given the limited size of the ensemble and the unavoidable existence of errors whose origin is unknown (i.e., system error), various approaches to localizing the impact of observations and to accounting for these errors have been proposed. However, challenges remain; for example, with regard to localization of multiscale phenomena (both in time and space). For the EnKF in general, but higher-resolution applications in particular, it is desirable to use a short assimilation window. This motivates a focus on approaches for maintaining balance during the EnKF update. Also discussed are limited-area EnKF systems, in particular with regard to the assimilation of radar data and applications to tracking severe storms and tropical cyclones. It seems that relatively less attention has been paid to optimizing EnKF assimilation of satellite radiance observations, the growing volume of which has been instrumental in improving global weather predictions. There is also a tendency at various centers to investigate and implement hybrid systems that take advantage of both the ensemble and the variational data assimilation approaches; this poses additional challenges and it is not clear how it will evolve. It is concluded that, despite more than 10 years of operational experience, there are still many unresolved issues that could benefit from further research.

Abstract (sommario):
Coagulase-positive Staphylococcus aureus were isolated from 449 (84.7%) of 530 meat and related samples obtained from traditional markets in Nigeria. All 100 fresh beef and associated 40 wash water and 40 drip water samples examined yielded coagulase-positive S. aureus compared with 258 (86%) of 300 Suya and 61 (61%) of 100 fried beef samples. Of the 449 coagulase-positive strains of S. aureus, 243 (54.1%) elaborated various enterotoxins. Suya (condiment - coated thin slices of skewered beef roasted over wood or charcoal flame) and fried beef yielded the highest proportions of enterotoxin producing strains of 59.3% and 58%, respectively. Relatively lower proportions of strains from fresh beef (52%) and water associated with fresh beef (45%) produced enterotoxin. Most of the organisms tested (139/57.2%) synthesized enterotoxin A (SEA). A few, 37 (15.2%), produced enterotoxin B (SEB), with fewer still producing enterotoxins D (SED, 6.2%) and C (SEC, 5.3%). It is suggested that the high level of contamination with S. aureus of the samples examined resulted from cross contamination, reflecting excessive hand contact with the foodstuffs.

Abstract (sommario):
Abstract Background. Cancer related anemia (CRA) is associated with increased symptom burden and reduced quality of life (QoL) compared to non-anemic subjects. Standard treatment guidelines for CRA recomend treatment when hemoglobin (Hb) declines to ≤ 10 g/dl. We compared patients with mild anemia to those with normal Hb level to assess clinical significance of mild anemia. Methods. 3416 patients from a large community oncology database sorted by gender and Hb were retrospectively reviewed. Patients receiving chemotherapy (<30 days) and/or growth factor (< 60 days) were excluded. Each case provided one Hb determination and same day self reported scores on the Cancer Care Monitor (CCM), a validated measure of symptom burden, functioning, and health related QoL comprising 6 scales. All CCM items are rated for symptom severity on a 0–10 scale. Effect sizes for male groups are calculated relative to normal males (Hb > 14), and effect sizes for females are calculated relative to normal females (Hb > 12). Positive effect size (Cohen’s exact d) values indicate greater symptom burden, and negative effect size values indicate lower quality of life. Results. Group differences on CCM measures were not accounted for by demographic, cancer diagnosis, and chemotherapy history differences. Table 1 shows a pattern of greater symptom burden, lower functioning, and worse QOL for males and females with mild anemia (p < .05). As compared to standards for minimal clinically important differences such as found with SF-36 (0.09 < Cohen’s d < 0.28). patients with mild anemia showed clinically significant differences in terms of effect size (0.11 < Cohen’s d < 0.61). Conclusions. The QoL impact of mild CRA is significant and failure to treat mild anemia may result in unnecessary symptom burden and noteworthy decrements in health related quality of life.

Abstract (sommario):
The process of generating the vast diversity of immunoglobulin receptors and secreted antibodies begins with the recombination of the joining (JH), diversity (DH) and variable (VH) genes in the immunoglobulin heavy chain locus. The ability to produce antibodies is restricted to the B cell lineage and is tightly regulated, starting with the temporal separation of the recombination process, in which DH-JH precedes VH-DHJH recombination. Successful recombination of both heavy and light chain loci results in the expression of an antigen receptor on the cell surface. Subsequent selection stages remove non‑functional and autoreactivity receptors from the final pool of antigen responding B cells that ultimately give rise to antibody secreting plasma cells. Understanding the complexity of the recombination processes and the diversity of the resulting antibody repertoire has been a major focus of academic and industrial research alike. Therapeutic monoclonal antibodies have seen many successful applications within the clinic and they constitute a billion-dollar industry. However, limitations therein have resulted in the emergence of antibody engineering approaches and the use of natural sources of alternative heavy chain only antibodies (HCAbs/nanobodies). The biotechnology company Crescendo Biologics has taken the highly desired characteristics of HCAbs a step further with the creation of a mouse platform capable of producing fully humanized HCAbs. The Crescendo platform presents a unique opportunity to expand our understanding of how mouse B cell development functions by exploiting the features of heavy chain only antibody production. Furthermore, the platform enables the expansion of our limited knowledge of the epigenetic mechanisms involved in the recombination of the human immunoglobulin heavy chain locus. Using flow cytometry, with dimensionality reduction analysis approaches, I investigated B cell development in the context of HCAbs. These studies revealed a previously uncharacterised developmentally intermediate B cell population. Due to ethical and availability limitations to studies of human bone marrow, the primary pre-selection human B cell repertoire has not been studied in detail. The isolation of several B cell developmental stages and the use of our novel DNA-based high-throughput unbiased repertoire quantification technique, VDJ-seq, allowed me to study recombination of the human IGH locus sequence and observe HCAb repertoire selection within the mouse environment. The adaptation of next generation sequencing techniques to antigen receptor repertoire quantification has provided an unprecedented insight into repertoire diversity and the alterations it undergoes during infection or ageing. Our VDJ-seq assay is unique in its ability to interrogate DNA recombinants. To expand its capabilities, I investigated several limitations of the technique, including mispriming and PCR/sequencing errors, and implemented experimental and bioinformatics solutions to overcome them, which included the creation of a comprehensive analysis workflow. Finally, I have developed and applied a novel network visualisation method for genome-wide promoter interaction data generated by promoter capture Hi-C. The availability of high quality human pluripotent stem cell datasets allowed me to utilise the new techniques to further our understanding of the dynamics of genome organisation during early human embryonic development. This visualisation approach will be directly applicable to understanding B cell development.

Abstract (sommario):
Le cycle cellulaire est constitue de deux phases majeures, la phase s (replication de l'adn) et la phase m (division cellulaire). Celles-ci sont separees par deux periodes gap(g1 and g2). Le cycle cellulaire est hautement regule par les kinases cycline-dependantes (les cdk). La transition g2/m est declenchee par un facteur universel, le mpf m-phase promoting factor, identifie comme un complexe constitue d'au moins deux sous-unites, la p34#c#d#c#2 et la cycline b#c#d#c#1#3. L'entree de la cellule en phase m est caracterisee par une activation de la kinase cdc2 suite a une dephosphorylation sur les residus thr14 et tyr15. Cette dephosphorylation est catalysee par la phosphatase cdc25. Parmi les proteines regulant la formation et l'activation du complexe p34#c#d#c#2/cycline b, la p13#s#u#c#1/p9#c#k#s#h#s semble jouer un role fondamental. La p9#c#k#s#h#s interagit avec la p34#c#d#c#2 a travers deux sites cooperatifs conduisants a la formation d'un complexe p9#c#k#s#h#s/p34#c#d#c#2 tres stable. In vitro, la p9#c#k#s#h#s peut s'assembler en une structure hexamerique impliquant une possible oligomerisation de la p34#c#d#c#2 in vivo.

Resumo: No presente trabalho, foi estudada a preparação da 5,8-dimetoxisoquinolina através de um expediente baseado na reação de Pomeranz-Fritsh. Na etapa de ciclização deste protocolo foi empregada a N-(2,5-dimetoxibenzil)-2,2-dimetoxietanamina, além de seus dois derivados com o nitrogênio protegido (grupo tosila ou nosila). O núcleo isoquinolíco foi preparado em quatro etapas, a partir de matérias comercialmente disponíveis, com 90% de rendimento. Posteriormente, a 5,8-dimetoxisoquinolina foi submetida à desproteção oxidativa, mediada por NBS ou ácidos trialoisocianúricos, seguida de uma etapa de aminação/oxidação. Assim, quatro produtos naturais foram preparados: as caulibugulonas A e D em cinco etapas e com rendimentos globais de 50% e 26% respectivamente e as caulibugulonas B e C em seis etapas com rendimentos globais de 31% e 61% respectivamente. Ainda, baseado nos estudos de obtenção das caulibugulonas A-D, foi possível preparar dois intermediários sintéticos, a 6-cloro-7-(fenilamino)isoquinolino-5,8-diona e a 7-(fenilamino)isoquinolino-5,8-diona) com rendimentos de 79% (duas etapas) e 45% (one-pot), respectivamente, a partir da isoquinolina. Na sequência, através de ciclização intramolecular promovida por fonte de paládio, a 5H-pirido[3,4-b]carbazol-5,11(10H)-diona foi preparada com 65% de rendimento a partir da 7-(fenilamino)isoquinolino-5,8-diona (via ativação C-H) ou com 50% de rendimento a partir da 6-cloro-7-(fenilamino)isoquinolino-5,8-diona (via arilação direta). Assim, após reações de metilação/redução, a isoelipticina foi preparada com 18% de rendimento global em nove etapas
Abstract: In the present work, the preparation of 5,8-dimethoxyisoquinoline was studied through an expedient based on the reaction of Pomeranz-Fritsh. In the cyclization step of this protocol was applied to N-(2,5-dimethoxy)-2,2-dimethoxyethanamine in addition to their two derivatives with protected nitrogen (nosyl or tosyl group). The isoquinolic core was prepared in four steps from commercially available materials, with 90% yield. Later 5,8-dimethoxyisoquinoline, was subjected to oxidative deprotection, mediated by NBS or trihaloisocyanuric acids, followed by one amination/oxidation step. Thus, the four natural products have been prepared: caulibugulones A and D in five steps and 50% and 26%, overall yield, respectively, and caulibugulones B and C in six steps with overall yields of 31% and 61% respectively. Also, based on studies by obtaining the caulibugulones A-D, it was possible to prepare two synthetic intermediates: 6-chloro-7-(phenylamino)-isoquinoline-5,8-dione and 7-(phenylamino)-isoquinoline-5,8-dione with 79% (two steps) and 45% (one-pot) yield, respectively, from the isoquinoline. Following, through intramolecular cyclization promoted by a source of palladium, 5H-pyrido[3,4-b]carbazole-5,11(10H)-dione was prepared in 65% yield from 7-(phenylamino)isoquinoline-5,8-dione (via C-H activation) or 50% yield from 6-chloro-7-(phenylamino)-isoquinoline-5,8-dione (via direct arylation).

Abstract (sommario):
In ASTM standard E1820, the single edge bend (SE(B)) geometry is one of those recommended for fracture toughness testing. The width to thickness (W/B) ratio recommended in E1820 for this specimen is 2. However, in certain cases, it is desirable to use specimens having alternative W/B ratios; the range of W/B suggested in E1820 is 1 to 4. In E1820, the crack size a may be evaluated during J-integral or CTOD resistance testing using the crack mouth opening displacement (CMOD) elastic unloading compliance C. The equation given to relate a to C using a dimensionless compliance BCE incorporates Young’s modulus E. For the three-dimensional (3-D) SE(B) specimens that are in neither plane stress nor plane strain condition, this parameter E may be considered as a normalizing parameter varying between extremes E (plane stress) and E/(1−ν2) (plane strain) depending on crack depth (a/W) and specimen W/B ratio. In the present study, 3-D finite element analysis (FEA) was used to evaluate the CMOD compliance of B×B SE(B) specimens with shallow and deep cracks and compared with that from Tada’s plane stress equation. Crack sizes evaluated using plane stress and plane strain assumptions with the 3-D CMOD compliance obtained from FEA were compared with the actual crack size of the specimens used in FEA. It was found that the errors in crack size using plane strain or plane stress assumptions can be larger than 5%, especially for shallow-cracked specimens. In the present study, an effective modulus with values between plane stress and plane strain is proposed and evaluated by FEA for the 3-D B×B SE(B) specimens. The values were fitted to a polynomial equation as a function of u = 1/(√(BCE)+1) for use in estimating the dimensionless compliance for crack size evaluation for B×B SE(B) specimens. It is shown that the errors in crack size evaluation can be significantly reduced using this effective modulus.
