Rhodopsin gene polymorphism associated with divergent light environments in atlantic cod

The spectral sensitivity of visual pigments in vertebrate eyes is optimized for specific light conditions. One of such pigments, rhodopsin (RH1), mediates dim-light vision. Amino acid replacements at tuning sites may alter spectral sensitivity, providing a mechanism to adapt to ambient light conditions and depth of habitat in fish. Here we present a first investigation of RH1 gene polymorphism among two ecotypes of Atlantic cod in Icelandic waters, which experience divergent light environments throughout the year due to alternative foraging behaviour. We identified one synonymous single nucleotide polymorphism (SNP) in the RH1 protein coding region and one in the 3' untranslated region (3'-UTR) that are strongly divergent between these two ecotypes. Moreover, these polymorphisms coincided with the well-known panthophysin (Pan I) polymorphism that differentiates coastal and frontal (migratory) populations of Atlantic cod. While the RH1 SNPs do not provide direct inference for a specific molecular mechanism, their association with this dim-sensitive pigment indicates the involvement of the visual system in local adaptation of Atlantic cod.

Stock structure of Atlantic herring Clupea harengus in the Norwegian Sea and adjacent waters

The genetic structure of Atlantic herring Clupea harengus L. was investigated in its north-easterly distribution in the Norwegian Sea and adjacent waters, using 23 neutral and one non-neutral (Cpa111) microsatellite loci. Fish from the suspected 2 main populations - the Norwegian spring-spawning herring (NSSH) and the Icelandic summer-spawning herring (ISSH) - were collected at spawning locations in their respective spawning seasons from 2009 to 2012. Samples were also collected from Norwegian autumn spawning locations, from different local Norwegian fjords such as the inner part of Trondheimsfjorden, Lindås pollene, Landvikvannet and Lusterfjorden, as well as from suspected Faroese spawning components. The observed level of genetic differentiation was significant but low (F_ST = 0.007) and mostly attributable to the differentiation of the local Norwegian fjord populations. The locus Cpa111, which was detected to putatively be under positive selection, exhibited the highest FST value (0.044). The observed genetic patterns were robust to exclusion of this locus. Landvikvannet herring was also genetically distinguishable from the 3 other fjord populations. In addition, the present study does not support genetic structuring among the ISSH and the NSSH.

Um modelo para a interpretação de polifonia renascentista

O presente trabalho é uma interpretação em consort de flautas de um corpo de obras seleccionadas dos manuscritos P-BRd 964 e P-CUG mm 242. Essa interpretação assenta no conceito de que a prática deve ser uma componente fundamental do estudo filológico e que apenas através da prática se pode produzir determinada forma de conhecimento que não é passível de verbalização. A tese divide-se em 6 partes: 1. estudo e transcrição do reportório seleccionado e sua contextualização histórica, social e estilística; 2. estudo sobre a flauta de bisel no Renascimento, com ênfase na tratadística e na análise dos instrumentos originais sobreviventes; 3. resumo da teoria musical do Renascimento que diz respeito à melodia e às categorizações modais e tonais; 4. estudo da prática interpretativa que regula a execução de polifonia em consort de flautas. A quinta parte deste trabalho explica as consequências práticas da aplicação do estudo filológico e a sexta é a interpretação propriamente dita, expressa no formato de um registo discográfico.

D. João de Magalhães e Avelar e a Fundação da Real Biblioteca Pública Municipal do Porto (1833)

D. João de Magalhães e Avelar (1754-1833) formou aquela que, ao tempo, era a maior biblioteca privada portuguesa. Com cerca de 36000 volumes, foi elogiada por personalidades nacionais e estrangeiras, por aliar à quantidade de volumes inúmeros e valiosíssimos manuscritos. Formada ao longo dos séculos XVIII e XIX, durante mais de 30 anos, originou, em 1833, o primeiro núcleo da actual Biblioteca Pública Municipal do Porto. Numa época em que possuir livros era sinónimo de prestígio social mas num período em que quase não havia tradição de bibliotecas públicas no nosso país, contrariamente ao que acontecia noutras realidades, a livraria privada de Avelar formou, com outras, a Real Biblioteca Pública da Cidade do Porto. Em 1833, aquando do primeiro aniversário da entrada do exército liberal no Porto, por decreto, criou-se a biblioteca portuense. Estabelecida na casa que servia de Hospício dos Religiosos de Santo António do Val da Piedade, à praça da Cordoaria, tinha como objectivo satisfazer a utilidade pública, estando aberta todos os dias, excepto domingos e feriados. Propriedade da cidade do Porto, ficava sujeita à administração da Câmara que se obrigava à sua guarda, manutenção, conservação, bem como à constante aquisição de espólio. Como veremos, tratou-se de um processo conflituoso mas o Porto obtinha, definitivamente, a sua biblioteca pública.

ESCMID* guideline for the diagnosis and management of Candida diseases 2012: developing European guidelines in clinical microbiology and infectious diseases.

The process to develop a guideline in a European setting remains a challenge. The ESCMID Fungal Infection Study Group (EFISG) successfully achieved this endeavour. After two face-to-face meetings, numerous telephone conferences, and email correspondence, an ESCMID task force (basically composed of members of the Society's Fungal Infection Study Group, EFISG) finalized the ESCMID diagnostic and management/therapeutic guideline for Candida diseases. By appreciating various patient populations at risk for Candida diseases, four subgroups were predefined, mainly ICU patients, paediatric, HIV/AIDS and patients with malignancies including haematopoietic stem cell transplantation. Besides treatment recommendations, the ESCMID guidelines provide guidance for diagnostic procedures. For the guidelines, questions were formulated to phrase the intention of a given recommendation, for example, outcome. The recommendation was the clinical intervention, which was graded by a score of A-D for the 'Strength of a recommendation'. The 'level of evidence' received a score of I-III. The author panel was approved by ESCMID, European Organisation for Research and Treatment of Cancer, European Group for Blood and Marrow Transplantation, European Society of Intensive Care Medicine and the European Confederation of Medical Mycology. The guidelines followed the framework of GRADE and Appraisal of Guidelines, Research, and Evaluation. The drafted guideline was presented at ECCMID 2011 and points of discussion occurring during that meeting were incorporated into the manuscripts. These ESCMID guidelines for the diagnosis and management of Candida diseases provide guidance for clinicians in their daily decision-making process.

Homer and the New Testament as "Multitexts" in the Digital Age ?

The field of classical studies has undergone a radical transformation with the arrival of the digital age, particularly with regard to the editing of ancient texts. As Umberto Eco (2003) pointed out, the digital age may mean the end of the history of variants and of the notion of the "original text." Among the texts of antiquity, the editing of Homer and of the New Testament are more especially susceptible to the effects of digital technology because of their numerous manuscripts. Whereas the "Homer Multitext" project recognizes that the notion of a synthetic critical edition is now seriously brought into question, the prototype of the online Greek New Testament continues to be based on the aim of obtaining a unique text, in the style of a printed critical edition. As it moves from a printed culture to the digital age, the editing of the Greek NT is also confronted by the emergence of non-Western scholarship. For example, the presence is to be noted of Arabic Muslim websites that examine Greek New Testament manuscripts but without directly interacting with Western scholarship.

Genome-wide meta-analysis for serum calcium identifies significantly associated SNPs near the calcium-sensing receptor (CASR) gene.

Calcium has a pivotal role in biological functions, and serum calcium levels have been associated with numerous disorders of bone and mineral metabolism, as well as with cardiovascular mortality. Here we report results from a genome-wide association study of serum calcium, integrating data from four independent cohorts including a total of 12,865 individuals of European and Indian Asian descent. Our meta-analysis shows that serum calcium is associated with SNPs in or near the calcium-sensing receptor (CASR) gene on 3q13. The top hit with a p-value of 6.3 x 10(-37) is rs1801725, a missense variant, explaining 1.26% of the variance in serum calcium. This SNP had the strongest association in individuals of European descent, while for individuals of Indian Asian descent the top hit was rs17251221 (p = 1.1 x 10(-21)), a SNP in strong linkage disequilibrium with rs1801725. The strongest locus in CASR was shown to replicate in an independent Icelandic cohort of 4,126 individuals (p = 1.02 x 10(-4)). This genome-wide meta-analysis shows that common CASR variants modulate serum calcium levels in the adult general population, which confirms previous results in some candidate gene studies of the CASR locus. This study highlights the key role of CASR in calcium regulation.

An analysis of protocols and publications suggested that most discontinuations of clinical trials were not based on preplanned interim analyses or stopping rules.

OBJECTIVES: To investigate the frequency of interim analyses, stopping rules, and data safety and monitoring boards (DSMBs) in protocols of randomized controlled trials (RCTs); to examine these features across different reasons for trial discontinuation; and to identify discrepancies in reporting between protocols and publications. STUDY DESIGN AND SETTING: We used data from a cohort of RCT protocols approved between 2000 and 2003 by six research ethics committees in Switzerland, Germany, and Canada. RESULTS: Of 894 RCT protocols, 289 prespecified interim analyses (32.3%), 153 stopping rules (17.1%), and 257 DSMBs (28.7%). Overall, 249 of 894 RCTs (27.9%) were prematurely discontinued; mostly due to reasons such as poor recruitment, administrative reasons, or unexpected harm. Forty-six of 249 RCTs (18.4%) were discontinued due to early benefit or futility; of those, 37 (80.4%) were stopped outside a formal interim analysis or stopping rule. Of 515 published RCTs, there were discrepancies between protocols and publications for interim analyses (21.1%), stopping rules (14.4%), and DSMBs (19.6%). CONCLUSION: Two-thirds of RCT protocols did not consider interim analyses, stopping rules, or DSMBs. Most RCTs discontinued for early benefit or futility were stopped without a prespecified mechanism. When assessing trial manuscripts, journals should require access to the protocol.
