The psychoneuroimmunological effects of music: a systematic review and a new model. - http://www.ncbi.nlm.nih.gov/pubmed...
Related Articles The psychoneuroimmunological effects of music: a systematic review and a new model. Brain Behav Immun. 2014 Feb;36:15-26 Authors: Fancourt D, Ockelford A, Belai A Abstract There has been a growing interest over the past decade into the health benefits of music, in particular examining its psychological and neurological effects. Yet this is the first attempt to systematically review publications on the psychoneuroimmunology of music. Of the selected sixty-three studies published over the past 22 years, a range of effects of music on neurotransmitters, hormones, cytokines, lymphocytes, vital signs and immunoglobulins as well as psychological assessments are cataloged. Research so far points to the pivotal role of stress pathways in linking music to an immune response. However, several challenges to this research are noted: (1) there is very little discussion on the possible mechanisms by which music is achieving its neurological and immunological impact; (2) the studies...

Avian picornaviruses: Molecular evolution, genome diversity and unusual genome features of a rapidly expanding group of viruses in birds. - http://www.ncbi.nlm.nih.gov/pubmed...
Related Articles Avian picornaviruses: Molecular evolution, genome diversity and unusual genome features of a rapidly expanding group of viruses in birds. Infect Genet Evol. 2014 Sep 30; Authors: Boros A, Pankovics P, Reuter G Abstract Picornaviridae is one of the most diverse families of viruses infecting vertebrate species. In contrast to the relative small number of mammal species compared to other vertebrates, the abundance of mammal-infecting picornaviruses was significantly overrepresented among the presently known picornaviruses. Therefore most of the current knowledge about the genome diversity/organization patterns and common genome features were based on the analysis of mammal-infecting picornaviruses. Beside the well known reservoir role of birds in case of several emerging viral pathogens, little is known about the diversity of picornaviruses circulating among birds, although in the last decade the number of known avian picornavirus species with complete genome was...

Related Articles Cryptococcus gattii Infections. Clin Microbiol Rev. 2014 Oct;27(4):980-1024 Authors: Chen SC, Meyer W, Sorrell TC Abstract SUMMARY: Understanding of the taxonomy and phylogeny of Cryptococcus gattii has been advanced by modern molecular techniques. C. gattii probably diverged from Cryptococcus neoformans between 16 million and 160 million years ago, depending on the dating methods applied, and maintains diversity by recombining in nature. South America is the likely source of the virulent C. gattii VGII molecular types that have emerged in North America. C. gattii shares major virulence determinants with C. neoformans, although genomic and transcriptomic studies revealed that despite similar genomes, the VGIIa and VGIIb subtypes employ very different transcriptional circuits and manifest differences in virulence phenotypes. Preliminary evidence suggests that C. gattii VGII causes severe lung disease and death without dissemination, whereas C. neoformans disseminates...

Biological and taxonomic perspective of triterpenoid glycosides of sea cucumbers of the family Holothuriidae (Echinodermata, Holothuroidea). Comp Biochem Physiol B Biochem Mol Biol. 2014 Sep 25; Authors: Honey-Escandón M, Arreguín-Espinosa R, Solís-Marín FA, Samyn Y Abstract Since the discovery of saponins in sea cucumbers, more than 150 triterpene glycosides have been described for the class Holothuroidea. The family Holothuriidae has been increasingly studied in search for these compounds. With many species awaiting recognition and formal description this family currently consists of five genera and the systematics at the species-level taxonomy is, however, not yet fully understood. We provide a bibliographic review of the triterpene glycosides that has been reported within the Holothuriidae and analyzed the relationship of certain compounds with the presence of Cuvierian tubules. We found 40 species belonging to four genera and 121 compounds. Holothurin A and B are the most common...

METHODS: We undertook a systematic review of existing supported accommodation classification systems. Using a structured system for qualitative data analysis, we reviewed the stratification features in these classification systems, identified the key elements of supported accommodation and arranged them into domains and dimensions to create a new taxonomy. The existing classification systems were mapped onto the new taxonomy to verify the domains and dimensions. RESULTS: Existing classification systems used either a service-level...

Wei Sheng Wu Xue Bao. 2014 May 4;54(5):487-97 Authors: Tang Q, Zhu H, Qin W Abstract Most members of the Burkholderia cepacia complex (Bcc) are important human opportunistic pathogens. Although progress has been achieved on the taxonomy and molecular identification of these bacteria, the molecular mechanisms of Bcc pathogenicity remain unclear and little development is made for new therapeutic agents. As Bcc is resistant to many common clinically-relevant antibiotics, revealing its virulence determinants is therefore very important to develop novel antibiotics or alternative anti-infective therapies. In this review, we summarize current advances in principal virulence determinants, limitations and genetic tools for studies of pathogenesis of Bcc. We primarily focus on key pathogenicity factors, including innate resistance to antibiotics, protein secretion system, and quorum-sensing...

Rev Biol Trop. 2014 Apr;62 Suppl 2:249-73 Authors: Ríos-Touma B, Acosta R, Prat N Abstract Score-based biotic indices are widely used to evaluate the water quality of streams and rivers. Few adaptations of these indices have been done for South America because there is a lack of knowledge on macroinvertebrate taxonomy, distribution and tolerance to pollution in the region. Several areas in the Andes are densely populated and there is need for methods to assess the impact of increasing human pressures on aquatic ecosystems. Considering the unique ecological and geographical features of the Andes, macroinvertebrate indices used in other regions must be adapted with caution. Here we present a review of the literature on macroinvertebrate distribution and tolerance to pollution in Andean areas above 2,000 masl. Using these data, we propose...

We provide a brief historical overview of socio-technical IS research and review studies investigating the impact of IT on organizational structures in the last five decades, identifying a dominating (new) research theme in each decade. A key overall impact of IT in all decades has been a dramatic decrease in transaction costs making it increasingly easier for organizations to source from external providers. A five level taxonomy of sourcing arrangement is developed together with a framework of organizational activities, and a number of significant cases are offered of how organizations are sourcing practically all types of business processes, including innovation.

Molecular epidemiology, phylogeny and evolution of dermatophytes. - http://www.ncbi.nlm.nih.gov/pubmed...
Related Articles Molecular epidemiology, phylogeny and evolution of dermatophytes. Infect Genet Evol. 2013 Dec;20:336-51 Authors: Cafarchia C, Iatta R, Latrofa MS, Gräser Y, Otranto D Abstract Dermatophytes are fungi that invade and propagate in the keratinized skin of mammals, including humans, often causing contagious infections. The species of medical concern belong to the genera Microsporum, Trichophyton, Epidermophyton (in their anamorphic state) and Arthroderma (in their telomorphic state), which were traditionally identified based on their morphology and biochemical characters. Nonetheless, limitations linked to the differentiation of closely related agents at species and strains level have been recently overcome by molecular studies. Indeed, an accurate identification of dermatophytes is pivotal for the establishment of effective control and prevention programs as well as for determining the most appropriate and effective antifungal therapies to be applied.

Related Articles Molecular pathology and genetics of gastrointestinal neuroendocrine tumours. Curr Opin Endocrinol Diabetes Obes. 2014 Feb;21(1):22-7 Authors: Lewis MA, Yao JC Abstract PURPOSE OF REVIEW: Neuroendocrine tumours (NETs) of the luminal gastrointestinal tract and pancreas are increasing in incidence and prevalence. Prior assumptions about the benign nature of 'carcinoids' and the clinical importance of distinguishing functional vs. nonfunctional tumours are being overturned through greater understanding of disease behaviour and heterogeneity. This review highlights the most contemporary genetic and molecular insights into gastroenteropancreatic NETs. RECENT FINDINGS: Biomarkers such as neuron-specific enolase or chromogranin A could be supplemented or supplanted by PCR-based analysis of NET genes detectable in the blood transcriptome. Conventional pathology, including Ki67 testing, could be enhanced with immunohistochemistry and exome analysis. Prognostic markers and/or...

Child Adolesc Psychiatr Clin N Am. 2014 Oct;23(4):965-972 Authors: Faraone SV, Antshel KM Abstract We have created an evidence-based guide for clinicians to the relative utility of nonpharmacologic treatments for attention-deficit/hyperactivity disorder (ADHD). This article uses the term evidence-based in the sense applied by the Oxford Center for Evidenced-Based Medicine to help readers understand the degree to which nonpharmacologic treatments are supported by the scientific literature. This article also reviews the magnitude of the treatment effect expressed as the standardized mean difference effect size (also known as Cohen D). It then describes a meta-algorithm to describe how to integrate pharmacologic and nonpharmacologic treatments for ADHD. PMID: 25220096 [PubMed - as supplied by publisher]

Related Articles A construct divided: prosocial behavior as helping, sharing, and comforting subtypes. Front Psychol. 2014;5:958 Authors: Dunfield KA Abstract The development and maintenance of prosocial, other-oriented behaviors has been of considerable recent interest. Though it is clear that prosocial behaviors emerge early and play a uniquely important role in the social lives of humans, there is less consensus regarding the mechanisms that underlie and maintain these fundamental acts. The goal of this paper is to clarify inconsistencies in our understanding of the early emergence and development of prosocial behavior by proposing a taxonomy of prosocial behavior anchored in the social-cognitive constraints that underlie the ability to act on behalf of others. I will argue that within the general domain of prosocial behavior, other-oriented actions can be categorized into three distinct types (helping, sharing, and comforting) that reflect responses to three distinct negative...

A Taxonomy for Mechanical Ventilation: 10 Fundamental Maxims. - http://www.ncbi.nlm.nih.gov/pubmed...
Related Articles A Taxonomy for Mechanical Ventilation: 10 Fundamental Maxims. Respir Care. 2014 Aug 12; Authors: Chatburn RL, Khatib ME, Mireles-Cabodevila E Abstract The American Association for Respiratory Care has declared a benchmark for competency in mechanical ventilation that includes the ability to "apply to practice all ventilation modes currently available on all invasive and noninvasive mechanical ventilators." This level of competency presupposes the ability to identify, classify, compare, and contrast all modes of ventilation. Unfortunately, current educational paradigms do not supply the tools to achieve such goals. To fill this gap, we expand and refine a previously described taxonomy for classifying modes of ventilation and explain how it can be understood in terms of 10 fundamental constructs of ventilator technology: (1) defining a breath, (2) defining an assisted breath, (3) specifying the means of assisting breaths based on control variables specified by the...
