This study analyzed the use of acknowledgements in medical articles published in five countries (Venezuela, Spain, France, UK and USA) from 1950 to 2010. For each country, we selected 54 papers (18 research papers, 18 reviews and 18 case reports), evenly distributed over six decades, from two medical journals with the highest impact factors. Only papers(More)
In this study we analyse a corpus of 300 randomly selected research paper titles written in English and published between 1998 and 2012 in the most prestigious journals in the field of Astrophysics, an under-researched discipline from a linguistic standpoint. We specifically address issues related to the evolution of titles, their length, their lexical(More)
Esophageal atresia is a rare condition (1:2,500-4,500), incompatible with life, and a surgical emergency in the neonatal period. It is associated with prematurity in 30% of cases, and to congenital abnormalities in 50% of cases, especially cardiac anomalies. Major congenital heart diseases and low weight are independent predictors of mortality and critical(More)
A trehalose-containing glycolipid was detected in several strains of Mycobacterium fortuitum and characterized as 2,3-di-O-acyltrehalose (DAT) by combined NMR spectroscopy, IR spectroscopy, GLC and GLC-MS. Lipid constituents of the molecule were identified as a mixture of straight-chain (14-18 carbon atoms) and methyl-branched-chain (17-21 carbon atoms)(More)
Habitat fragmentation and loss are important drivers of genetic differentiation, often leading to a decrease in genetic diversity. Yet, natural populations of tropical bees often show a lack of differentiation, even in fragmented landscapes, suggesting resilience to deal with unfavourable land use. It is not clear what leads to this lack of differentiation,(More)

Introduction. We report an investigation on collaboration practices in research papers published in the most prestigious English-medium astrophysics journals. Method. We propose an evaluation method based on three numerical indicators to study and compare, in absolute terms, three different types of collaboration (international, national and local) and(More)
BACKGROUND Several glycolipids of Mycobacterium tuberculosis are antigenic and their use in the serodiagnosis of pulmonary tuberculosis has been postulated. Acyltrehaloses (SL-IV) are among the strongest antigenic glycolipids of M. tuberculosis; similar compounds have been found in M. fortuitum. The aim of the present study was to evaluate the usefulness of(More)
Fluid replacement therapy for pediatric patients in the past 50 years has meant the infusion of hypotonic solutions in amounts calculated using the Holliday-Segar formula. Recent studies have focused attention on the incidence of postoperative hyponatremia and associated morbidity and mortality rates, generating debate on the advisability of perioperative(More)
