TL;DR: It is suggested that AMC and PTZ are suitable alternatives to carbapenems for treating patients with bloodstream infections due to ESBL-EC if active in vitro and would be particularly useful as definitive therapy.
Abstract: Background Extended-spectrum s-lactamase-producing Escherichia coli (ESBL-EC) is an important cause of invasive infections. Alternatives to carbapenems--considered the drugs of choice--are needed because of the emergence of carbapenemase-producing enterobacteria. The efficacy of s-lactam/s-lactam inhibitors (BLBLI) in such infections is controversial. Methods The authors performed a post hoc analysis of patients with bloodstream infections due to ESBL-EC from 6 published prospective cohorts. Mortality and length of hospital stay in patients treated with an active BLBLI (amoxicillin-clavulanic acid [AMC] and piperacillin-tazobactam [PTZ]) or carbapenem were compared in 2 cohorts: the empirical therapy cohort (ETC) and the definitive therapy cohort (DTC). Confounding was controlled by multivariate analysis; for patients in the ETC, a propensity score for receiving carbapenem was also used. Results The ETC included 103 patients (BLBLI, 72; carbapenem, 31), and the DTC included 174 (BLBLI, 54; carbapenem, 120). Mortality rates at day 30 for those treated with BLBLI versus carbapenems were 9.7% versus 19.4% for the ETC and 9.3% versus 16.7% for the DTC, respectively (P > .2, log-rank test). After adjustment for confounders, no association was found between either empirical therapy with BLBLI (adjusted hazard ratio [HR], 1.14; 95% confidence interval [CI], .29-4.40; P = .84) or definitive therapy (adjusted HR, 0.76; 95% CI, .28-2.07; P = .5) and increased mortality. Furthermore, BLBLI therapy, with respect to carbapenem, was not found to influence length of hospital stay. Conclusions These results suggest that AMC and PTZ are suitable alternatives to carbapenems for treating patients with bloodstream infections due to ESBL-EC if active in vitro and would be particularly useful as definitive therapy.

TL;DR: An integrative view is provided on how transcription can control different aspects of genomic integrity, by exploring different mechanisms that might be responsible for transcription‐associated mutation (TAM) and transcription‐ associated recombination (TAR).
Abstract: Transcription is a central aspect of DNA metabolism that takes place on the same substrate as replication, repair and recombination. Not surprisingly, therefore, there is a physical and functional connection between these processes. In recent years, transcription has proven to be a relevant player in the maintenance of genome integrity and in the induction of genetic instability and diversity. The aim of this review is to provide an integrative view on how transcription can control different aspects of genomic integrity, by exploring different mechanisms that might be responsible for transcription-associated mutation (TAM) and transcription-associated recombination (TAR).

TL;DR: In this paper, the specific influence of the new socioeconomic factor of social capital on the formation of entrepreneurial intentions was analyzed, and an empirical study was carried out using the Partial Least Squares (PLS) technique with data from a sample of young undergraduate students in the last year of their degree.
Abstract: Nowadays, the scientific community assigns both social context and entrepreneurs’ behavior as a central role in the growth and development of the world economy. However, the relationships between these two factors have not been sufficiently studied in business and economics. Therefore, in this paper, the specific influence of the new socioeconomic factor of social capital on the formation of entrepreneurial intentions will be analyzed. To test the theoretical hypotheses, an empirical study will be carried out using the Partial Least Squares (PLS) technique with data from a sample of young undergraduate students in the last year of their degree. This population has been selected because these individuals, according to different studies, show a higher propensity towards firm creation.

TL;DR: Current evidence for oxidative damage in chronic inflammatory periodontal disease, and the possible therapeutic effects of anti-oxidants in treating and/or preventing such pathology, are reviewed, with special attention to vitamin E and Co-enzyme Q.
Abstract: In recent years, there has been a tremendous expansion in medical and dental research concerned with free radicals, reactive oxygen species, and anti-oxidant defense mechanisms. This review is intended to provide a critical, up-to-date summary of the field, with particular emphasis on its implications for the application of "anti-oxidant therapy" in periodontal disease. We have reviewed the nomenclature, mechanisms of actions, features, and sources of most common free radicals and reactive oxygen species, as well as analyzed the typical biological targets for oxidative damage. Based on a review of direct and indirect anti-oxidant host defenses, particularly in relation to the key role of polymorphonuclear neutrophils in periodontitis, we review current evidence for oxidative damage in chronic inflammatory periodontal disease, and the possible therapeutic effects of anti-oxidants in treating and/or preventing such pathology, with special attention to vitamin E and Co-enzyme Q.

TL;DR: By using sol-gel chemistry, innocuous solvents such as glycerol and olive oil, and electrohydrodynamics, it is possible to make such structures in a rather straightforward manner.
Abstract: The outer liquid of a two-liquid coaxial electrified jet is gelled before the onset of natural instabilities to yield hollow nanofibers. By using sol−gel chemistry, innocuous solvents such as glycerol and olive oil, and electrohydrodynamics, it is possible to make such structures in a rather straightforward manner.
