BACKGROUND: Laparoscopic sleeve gastrectomy (SG) as a single-stage procedure for the treatment of morbid obesity is becoming increasingly popular. In undeveloped countries, the linear staples required to create the sleeve are not always available because of their high cost. As an alternative to the staples, the bipolar vessel sealer device could be used in bariatric surgery to divide and temporarily seal the stomach. SETTINGS: Universidad Central de Venezuela, Caracas, Venezuela...

A growing body of knowledge on the diversity and evolution of intertidal isopods across different regions worldwide has enhanced our understanding on biological diversification at the poorly studied, yet vast, sea-land interface. High genetic divergences among numerous allopatric lineages have been identified within presumed single broadly distributed species. Excirolana mayana is an intertidal isopod that is commonly found in sandy beaches throughout the Gulf of California. Its distribution in the Pacific extends from this basin to Colombia and in the Atlantic from Florida to Venezuela...

Dengue, the predominant arthropod-borne viral disease affecting humans, is caused by one of four distinct serotypes (DENV-1, -2, -3 or -4). A literature analysis and review was undertaken to describe the molecular epidemiological trends in dengue disease and the knowledge generated in specific molecular topics in Latin America, including the Caribbean islands, from 2000 to 2013 in the context of regional trends in order to identify gaps in molecular epidemiological knowledge and future research needs. Searches of literature published between 1 January 2000 and 30 November 2013 were conducted using specific search strategies for each electronic database that was reviewed...

REVIEW

Halstedian method of surgical training has been the mainstay of surgical education for many decades. Onsite knowledge sources in surgery have traditionally been textbooks, which are often a number of years out of date or teaching rounds with a Professor or senior colleague that enables a small number of trainees to benefit from. Congresses have been a good way of learning new developments in the field, but they often require travelling and are very costly. We have identified web-based education as a means of linking experts with trainees, regardless of their geographic location and often without requiring any substantial capital...

The region of Latin America, which includes Central America, the Caribbean and South America, is one that is rapidly developing. Signified by socio-economic growth, transition and development over the last few decades, living standards in countries like Brazil and Mexico have improved dramatically, including improvements in education and health care. An important marker of socio-economic change has been the epidemiological shift in disease burden. Cardiovascular disease is now the leading cause of death in Latin America, and the drop in prevalence of infectious diseases has been accompanied by a rise in non-communicable diseases...

INTRODUCTION: Zika virus is mainly transmitted through the bites of infected Aedes mosquitoes, although mother-to-child and sexual transmission have also been described. The presence of Zika virus in semen after infection seems to be not uncommon, but the duration of viral persistence has not been well-determined. METHODS: Molecular, serological and cell culture methods were used for the diagnosis and follow up of a case of Zika virus infection imported from Venezuela...

: Bacteriophages are the source of many valuable tools for molecular biology and genetic manipulation. In Streptomyces, most DNA cloning vectors are based on serine integrase site-specific DNA recombination systems derived from phage. Because of their efficiency and simplicity, serine integrases are also used for diverse synthetic biology applications. Here we present the genome of a new Streptomyces phage, ϕJoe, and investigate the conditions for integration and excision of the φJoe genome...

REVIEW
Keith F Chater
About 2,500 papers dated 2014-2016 were recovered by searching the PubMed database for Streptomyces, which are the richest known source of antibiotics. This review integrates around 100 of these papers in sections dealing with evolution, ecology, pathogenicity, growth and development, stress responses and secondary metabolism, gene expression, and technical advances. Genomic approaches have greatly accelerated progress. For example, it has been definitively shown that interspecies recombination of conserved genes has occurred during evolution, in addition to exchanges of some of the tens of thousands of non-conserved accessory genes...

Trehalose-6-phosphate synthase OtsA from streptomycetes is unusual in that it uses GDP-glucose as the donor substrate rather than the more commonly used UDP-glucose. We now confirm that OtsA from Streptomyces venezuelae has such a preference for GDP-glucose and can utilise ADP-glucose to some extent too. A crystal structure of the enzyme shows that it shares twin Rossmann-like domains with the UDP-glucose-specific OtsA from Escherichia coli However, it is structurally more similar to Streptomyces hygroscopicus VldE, a GDP-valienol-dependent pseudo-glycosyltransferase enzyme...

: Many studies have explored the links between music and children's outcomes; however, study designs have not been sufficiently rigorous to support causal findings. This study aims to assess the effects of a large-scale music program on children's developmental functioning in the context of high rates of exposure to violence. The paper describes the results of an experimental evaluation of Venezuela's National System of Youth and Children's Orchestras. The curriculum of the program, better known as "El Sistema," emphasizes social interactions through group instruction and group performances...

Streptomyces avermitilis is an actinobacterium known to produce clinically useful macrolides including avermectins. CYP107L2 from S. avermitilis shares a high sequence similarity with the PikC (CYP107L1) from S. venezuelae. To elucidate the structural features of CYP107L2, we conducted biochemical and structural characterization of CYP107L2 from S. avermitilis. The CYP107L2 gene was cloned, and its recombinant protein was expressed and purified. The CYP107L2 showed a low-spin state of heme, and the reduced form yielded the CO difference spectra with a maximal absorption at 449 nm...

One hundred twenty Rhodnius prolixus (Stal) (Hemiptera: Reduviidae) specimens from 6 Colombian Departments and 1 Venezuelan State had 594-bp of the mitochondrial cytochrome-b gene sequenced to improve the understanding of evolutionary processes that shape the main vector of Chagas disease. The levels of genetic diversity for this species were low-medium with reference to other bugs. The genetic heterogeneity among the populations was very limited which means there has been extensive gene flow and/or very recent split processes...
