Integrons are genetic elements known for their role in the acquisition and expression of genes conferring antibiotic resistance. Such acquisition is mediated by an integron-encoded integrase, which captures genes that are part of gene cassettes. To test whether integrons occur in environments with no known history of antibiotic exposure, PCR primers were(More)
Integron-encoded integrases recognize two distinct types of recombination site: attI sites, found in integrons, and members of the 59-base element (59-be) family, found in the integron-associated gene cassettes. The class 1 integron integrase, IntI1, catalyses recombination between attI1 and a 59-be, two 59-be, or two attI1 sites, but events involving two(More)
Autophagy is a process that sequesters and degrades altered organelles and macromolecular cytoplasmic constituents for cellular restructuring and repair, and as a source of nutrients for metabolic use in early starvation it may be involved in anti-aging mechanisms of caloric restriction. The effects of 40% daily dietary restriction (DR) and intermittent(More)
Integrons determine a site-specific recombination system which is responsible for the acquisition of genes, particularly antibiotic resistance genes. The integrase encoded by integrons recognises two distinct classes of recombination sites. The first is the family of imperfect inverted repeats, known as 59-base elements, which are associated with the mobile(More)
In the last several years pharmacogenetics and pharmacogenomics have attracted the interest of the scientific community and of important pharmaceutical groups. What is the consequence for medicine and for the pharmaceutical industry? What has emerged from this investment, and what can we expect for the future? As with many new technologies, pharmacogenetics(More)
This multicentre, observational, cross-sectional study was conducted to determine migraine prevalence in a sample of population presenting to their GPs. The study covered all the patients who visited the GPs practice, for any reason, on 5 consecutive days of 2 different weeks. A total of 71,588 patients were interviewed by 902 GPs. The prevalence of(More)
Benzodiazepines (BDZ), the most popular drug of choice for treating anxiety disorders, present side-effects such as sedation, muscular disorders, abuse liability and synergistic effect with alcohol and CNS depressant drugs. At present, pharmacological research is focusing to find anxiolytic drugs as efficacious as benzodiazepines but without side-effects.(More)
The clinical development of any drug used in the treatment of brain-ageing, poses many methodological problems regarding the difficulty in defining precisely the pathology, both from the point of view of diagnostic and of terminology, the lack of specific parameters for assessing the therapeutic efficacy and the difficulty of establishing homogeneous trial(More)
