Honeybees are threatened by various pathogens and parasites. More than 18 viruses have been described in honeybees and many of them have been detected in China and Argentina. In China, both Apis cerana and Apis mellifera are raised. In Argentina, beekeepers raise different ecotypes of A. mellifera: European honeybees (in both temperate and subtropical regions) and Africanised honeybees (in subtropical areas only). A thorough study was carried out in both China and Argentina to analyse the current virus presence and distribution in different climatic zones and gather information on different bee species/subspecies...

Caroline Sayuri Fukushima, Rogério Bertani
The genus Avicularia Lamarck, 1818 is revised and all species are rediagnosed. The type species, described as Aranea avicularia Linnaeus, 1758, is the oldest mygalomorph species described and its taxonomic history is extensive and confusing. Cladistic analyses using both equal and implied weights were carried out with a matrix of 46 taxa from seven theraphosid subfamilies, and 71 morphological and ecological characters. The optimal cladogram found with Piwe and concavity = 6 suggests Avicularia and Aviculariinae are monophyletic...

Biomedical Engineering (BME) is a new, multidisciplinary, and rapidly growing field, however, the BME Workforce suffers from limited ethnic and gender diversity. Despite the demand and growth of this new field due to its public health importance, only 4 out of the 107 Historically Black Colleges and Universities (HBCUs) nationwide offers a Bachelor's of Science (B.S.) in Bio-Engineering related fields. In order to contribute to a growing BME Workforce, HBCUs need to react and offer more degree-programs relevant to BME...

Domestic turkeys present several color phenotypes controlled by at least five genetic loci, but only one of these has been identified precisely: the bronze locus, which turned out to be the melanocortin-1 receptor (MC1R) gene. MC1R variation is important for breeders interested in maintaining or developing different color varieties. In this study, we sequenced most of the MC1R gene from 16 White Holland (the main commercial turkey variety) and 19 pigmented turkeys from southern Brazil with two purposes. The first was to describe the MC1R diversity in White Holland turkeys, which may serve as reservoirs of genetic diversity at this locus...

Luca Baiotti, Luciano Rezzolla
The merger of binary neutron-stars systems combines in a single process: extreme gravity, copious emission of gravitational waves, complex microphysics, and electromagnetic processes that can lead to astrophysical signatures observable at the largest redshifts. We review here the recent progress in understanding what could be considered Einstein's richest laboratory, highlighting in particular the numerous significant advances of the last decade. Although special attention is paid to the status of models, techniques, and results for fully general-relativistic dynamical simulations, a review is also offered on initial data and advanced simulations with approximate treatments of gravity...

Multisystemic therapy (MST) was developed to help youth with serious social, emotional, and behavioral problems. Research on the efficacy and effectiveness of MST has shown positive outcomes in different domains of development and functioning among various populations of youth. Nonetheless, even with a large body of literature investigating the treatment effects of MST, few studies have focused on the effectiveness of MST through large-scale dissemination efforts. Utilizing a large sample of youth involved in a statewide dissemination of MST (n = 740; 43% females; 14% Black; 29% Hispanic; 49% White; Mage = 14...

Black, Asian, and White participants (N = 210) created self-resembling avatars and engaged in peer-selection tasks during social events in the virtual world, Second Life, that were designed to simulate various types of resource competition. Participants in merit-based resource competition settings had less diversity in their peer groups compared to participants in settings where no resource competition was present, and Asian participants had lower preference for Black peers. Furthermore, these relationships were mediated by out-group discomfort...

REVIEW
Meagan Jacobs, Susan Levine, Kate Abney, Lester Davids
Skin-lightening is an aesthetic practice of global concern. By adopting a biopsycho-social approach, we consider the interplay between the biological, psychological and social factors that underpin the circulation and consumption of skin lighteners in South Africa. This paper reflects on biological aspects of skin lightening, interpersonal relationships, individual beliefs and expectations about the maintenance of health and well being that informs cosmetic practices. The paper seeks to examine claims made by historians (Thomas) and political philosophers and activists (Biko) that colonialism and apartheid in South Africa historically reinforced the use of skin lightening products in the country...

PURPOSE: The role of lateral extra-articular tenodesis (LEAT) as an augment to primary anterior cruciate ligament reconstruction (ACLR) remains controversial. However, concerns exist regarding the risk of development of osteoarthritis due to over constraint of the knee. To systematically review the literature to analyse the long-term incidence of osteoarthritis in patients who had an LEAT performed in isolation or in combination with intra-articular ACLR for the treatment of ACL deficiency...

A borehole drilling campaign has allowed the study of a former littoral lagoon located next to the harbour city of Cartagena in South-East Spain (close to the Sierra de Cartagena polymetallic ore deposits). This lagoon, which developed during the Holocene, was first a shallow sedimentary marine environment and later evolved into a swampy semi-endorheic basin named "Almarjal" (after the Arab term from the fourteenth century). The lagoon eventually dried out and at present forms part of the substratum of the modern sector of the city urban area...

In this study, Agrotis ipsilon nucleopolyhedrovirus bacmid has been constructed as an infectious bacmid in an attempt to allow genome recombination and generation of virus mutants. Since the FseI, a unique restriction site, is located in a viral coding region (ORF_119), PCR was performed to partially amplify the ORF_119 fragment containing the FseI site to facilitate the bacmid construction in a proper way without interrupting the ORF expression. Construction with repeated fragments at the end of the cloned viral was carried out in an attempt to facilitate circulation during infection in insect cells...

BACKGROUND: Males are born in excess of females, expressed as M/T (male/total births), which is expected to approximate 0.515. Racial M/T disparities have been long known. This study was carried out in order to identify such disparities in different races in the United States. DESIGN: Monthly male and female live births by race for the entire US were obtained from the website of the Centers for Disease Control and Prevention for 1995-2014 for the four racial groups: American Indian or Alaska Native, Asian or Pacific Islander, Black or African American and White...

Phytophthora megakarya (Pmeg) and Phytophthora palmivora (Ppal) cause black pod rot of Theobroma cacao L. (cacao). Of these two clade 4 species, Pmeg is more virulent and is displacing Ppal in many cacao production areas in Africa. Symptoms and species specific sporangia production were compared when the two species were co-inoculated onto pod pieces in staggered 24 h time intervals. Pmeg sporangia were predominantly recovered from pod pieces with unwounded surfaces even when inoculated 24 h after Ppal. On wounded surfaces, sporangia of Ppal were predominantly recovered if the two species were simultaneously applied or Ppal was applied first but not if Pmeg was applied first...

The aim of this study was to estimate uric acid renal stone prevalence rates of adults in different countries of the world. PubMed was searched for papers dealing with "urinary calculi and prevalence or composition" for the period from January 1996 to June 2016. Alternative searches were made to collect further information on specific topics. The prevalence rate of uric acid stones was computed by the general renal stone prevalence rate and the frequency of uric acid stones in each country. After the initial search, 2180 papers were extracted...

INTRODUCTION: Mishri is one of the form of smokeless tobacco, which is a roasted, powdered preparation made by baking tobacco on a hot metal plate until it is uniformly black, after which it is powdered. It is noted that mishri use is more commonly used by the women of low socioeconomic status, hence the need was felt to conduct this study among women mishri users of slums. Also, the consequences of mishri use are little known, hence an effort is made to find out its ill-effect on oral health...

Papaya crop is important to Brazilian agribusiness. However, the expansion of papaya cultivation in the country is affected by the absence of commercial cultivars presenting good disease resistance. The black-spot caused by the fungus Asperisporium caricae is the most damaging foliar disease affecting Brazilian papaya crops. The use of genetically resistant cultivars is a promising strategy to reduce the dependence of papaya crops on fungicides. A field split-plot experiment was carried out in the municipality of Linhares, Espírito Santo State, and included 20 hybrids derived from the cross between 14 superior lines and four elite genotypes ('SS72/12', 'SEKATI', 'JS/12' and '41/7'), two commercial cultivars ('Golden' and 'Tainung 01'), and the superior line '36/7', which were evaluated for resistance to black-spot in the fruits and leaves...

 Epigenetics has drawn much attention as a mechanism of transcriptional regulation involving modifications to genomic DNA and histone, without changes to nucleotide sequences. Epigenetics is related to various biological phenomena. We defined one of these phenomena as "epigenetic toxicity", in which chemicals affect epigenetic regulation and result in undesirable effects on living organisms. We then detailed the importance of epigenetics and the need for intensive research. Epigenetics is a mechanism that might explain the long-lasting effects of chemicals in an organism, and the formation of a predisposition to various diseases...

Surface passivation is a key limiting factor in the application of zero-valent iron (ZVI) for water remediation. Addition of ligands is a useful approach to overcome this issue. In this work, a small amount of acetylacetone (AA) (0.5 mM) was found highly efficient to enhance the reduction of nitrate by ZVI at near neutral conditions (pH 6.0) with the formation of considerable black coating on ZVI. At an initial nitrate concentration of 20 mg N/L, the pseudo first-order reduction rate constant of nitrate in the ZVI-AA-NO3(-) system was 0...
