Abstract	The pva gene from Streptomyces lavendulae ATCC 13664, encoding a novel penicillin V acylase (SlPVA), has been isolated and characterized. The gene encodes an inactive precursor protein containing a secretion signal peptide that is activated by two internal autoproteolytic cleavages that release a 25-amino-acid linker peptide and two large domains of 18.79 kDa (alpha-subunit) and 60.09 kDA (beta-subunit). Based on sequence alignments and the three-dimensional model of SlPVA, the enzyme contains a hydrophobicpocket involved in catalytic activity, including Serbeta1, Hisbeta23, Valbeta70, and Asnbeta272, which were confirmed by site-directed mutagenesis studies. The heterologous expression of pva in S. lividans led to the production of an extracellularly homogeneous heterodimeric enzyme at a 5-fold higher concentration (959 IU/liter) than in the original host and in a considerably shorter time. According to the catalytic properties of SlPVA, the enzyme must be classified as a new member of the Ntn-hydrolase superfamily, which belongs to a novel subfamily of acylases that recognize substrates with long hydrophobic acyl chains and have biotechnological applications in semisynthetic antifungal production.

Abstract	An eponym is a name based on the name of a person, frequently as a means to honor him/her, and it can be used to concisely communicate or summarize a complex abnormality or injury. However, inappropriate use of an eponym may lead to potentially dangerous miscommunication. Moreover, an eponym may honor the incorrect person or a person who falls into disrepute. Despite their limitations, eponyms are still widespread in medicine. Many commonly used eponyms applied to extremity fractures should be familiar to most emergency radiologists and have been previously reported. Yet, a number of non-extremity eponyms can be encountered in an emergency radiology practice as well. This other group of eponyms encompasses a spectrum of traumatic and nontraumatic pathology. In this second part of a two-part series, the authors discuss a number of non-extremity emergency radiology eponyms, including relevant clinical and imaging features, as well biographical information of the eponyms' namesakes.

Abstract	Background: In Vitis vinifera L., domestication induced a dramatic change in flower morphology: the wild sylvestris subspecies is dioecious while hermaphroditism is largely predominant in the domesticated subsp. V. v. vinifera. The characterisation of polymorphisms in genes underlying the sex-determining chromosomal region may help clarify the history of domestication in grapevine and the evolution of sex chromosomes in plants. In the genus Vitis, sex determination is putatively controlled by one major locus with three alleles, male M, hermaphrodite H and female F, with an allelic dominance M > H > F. Previous genetic studies located the sex locus on chromosome 2. We used DNA polymorphisms of geographically diverse V. vinifera genotypes to confirm the position of this locus, to characterise the genetic diversity and traces of selection in candidate genes, and to explore the origin of hermaphroditism. Results: In V. v. sylvestris, a sex-determining region of 154.8 kb, also present in other Vitis species, spans less than 1% of chromosome 2. It displays haplotype diversity, linkage disequilibrium and differentiation that typically correspond to a small XY sex-determining region with XY males and XX females. In male alleles, traces of purifying selection were found for a trehalose phosphatase, an exostosin and a WRKY transcription factor, with strikingly low polymorphism levels between distant geographic regions. Both diversity and network analysis revealed that H alleles are more closely related to M than to F alleles. Conclusions: Hermaphrodite alleles appear to derive from male alleles of wild grapevines, with successive recombination events allowing import of diversity from the X into the Y chromosomal region and slowing down the expansion of the region into a full heteromorphic chromosome. Our data are consistent with multiple domestication events and show traces of introgression from other Asian Vitis species into the cultivated grapevine gene pool.

Abstract	The global health promotion movement has been institutionalized for 35 years (1986-2001) since the First International Conference on Health Promotion in Ottawa, Canada. This essay establishes how the health promotion perspective has reshaped the nature, scope and perspectives of health, highlighting the urgency of approaching health from a more political and social vision. Health promotion should now deserve greater recognition by governmental, institutional, private and community authorities. Governments must politically reposition it as a proposal for social and human development. In tandem, higher education institutions should continue to exercise academic-professional leadership to promote training, research and social community linkages in the field of health promotion. Enhancing sustained efforts of regional health promotion networks and maintaining a healthy environments approach are the pillars to promoting participation along with political, social and community mobilization for health, equity and sustainable development.

Abstract	This essay discusses the need for schools of public health to convene to implement the practice of public health teaching and research by training health leaders, generating knowledge, and providing health and social services that contribute to the well-being of the community. Since their inception, the academic, research and service programs of some schools have been designed to serve as partners and allies of governments and the health sector in general. Part of their role has been to identify health risks to communities, design strategies to address major problems affecting health, create databases for assessment and intervention in conditions affecting the health of communities, as well as advise government authorities and other social sectors in health education efforts and preventive approaches. These programs have also been an essential part of the design, evaluation and implementation of organizational models of health services and institutional and community clinical care, in addition to integrate public health and health services in the development of unique models at the national level. Likewise, these have extended the scope of actions and services to other state agencies, companies and private health sector organizations, which benefit directly from the experience of the schools of public health. The academic, research and service programs have also strengthened the professional competencies of graduates of the academic programs, who occupy essential decision-making positions.

Article: Epitope selection for multipeptide proteins: the case of RNA polymerase IV and V

Abstract	Large multipeptide protein complexes have provided a challenge for epitope selection, which is required for immunological protocols where native conformations are needed. Immunolocalization requires native conformation of the proteins, which is essential for further understanding of biological activity. RNA polymerase IV and V are multisubunit proteins that interact with other factors in the RNA-directed DNA methylation pathway for control of DNA silencing by small interfering RNA and DNA methylation. DNA silencing is an important process during cell differentiation, nuclear structure and viral control among others. RNA polymerase IV and V are yet to be studied in model monocot systems like Oryza sativa, which may provide further data to define if the genetic silencing mechanism has diverged over time as compared to dicots. Here we show an in silico selection process of exposed sequences and their use for obtaining antibodies against native RNA polymerase IV and V in O. sativa.
