Understanding brain health is increasingly important, particularly in light of growing public health challenges related to neurological and psychiatric conditions. These include the rising prevalence of mental health disorders, such as depression and anxiety, as well as neurodegenerative diseases like Alzheimer's and Parkinson's. Lifestyle factors, including stress, poor diet, and insufficient physical activity, also significantly impact cognitive function.

The detection of rare or deviant stimuli shares common brain circuits involved in temporal processing and salience, critical for cognitive control. Disruption in these processes may contribute to the mechanisms of the disease and explain cognitive deficits observed in psychosis and related disorders. We designed a neuroimaging study, using oddball task-based functional sequences (fMRI) and diffusion tensor imaging (DTI), comparing healthy controls (HC, n = 14, 7 females) and patients with stable psychosis (PSY, n = 20, 10 females).

Our understanding of speciation processes in marine environments remains very limited and the role of different reproductive barriers are still debated. While physical barriers were considered important drivers causing reproductive isolation, recent studies highlight the importance of climatic and hydrological changes creating unsuitable habitat conditions as factors promoting population isolation. Although speciation in marine fish has been investigated from different perspectives, these studies often have a limited geographical extant.

Retractions are becoming increasingly common but still account for a small minority of published papers. It would be useful to generate databases where the presence of retractions can be linked to impact metrics of each scientist. We have thus incorporated retraction data in an updated Scopus-based database of highly cited scientists (top 2% in each scientific subfield according to a composite citation indicator).

A plasmid with the gene enhances the fitness of strains under laboratory conditions.

Microbiology (Reading)

January 2025

Instituto de Microbiologa, Colegio de Ciencias Biolgicas y Ambientales, Universidad San Francisco de Quito, Quito, Ecuador.

Antimicrobial resistance (AMR) is a major threat to global public health that continues to grow owing to selective pressure caused by the use and overuse of antimicrobial drugs. Resistance spread by plasmids is of special concern, as they can mediate a wide distribution of AMR genes, including those encoding extended-spectrum -lactamases (ESBLs). The CTX-M family of ESBLs has rapidly spread worldwide, playing a large role in the declining effectiveness of third-generation cephalosporins.

Universidad San Francisco de Quito, Colegio de Ciencias Biológicas Ambientales, Instituto de Microbiología, Quito, Ecuador.

Aim: To investigate the nucleotide sequences associated with transposable elements carrying bla allelic variants as potential markers for the transmission of antimicrobial resistance genes between domestic animals, humans and the environment.

Materials & Methods: We conducted whole-genome sequencing and analyzed the nucleotide sequences of most abundant bla allelic variants (bla, bla, and bla) in commensal Escherichia coli ( = 20) from household members in Quito and uropathogenic E. coli (UPEC) ( = 149) isolated from nine clinics in Quito, Ecuador.

Background: Autism spectrum disorder (ASD) is a heterogeneous neurobiological condition characterized by behavioral problems and delayed neurodevelopment. Although transcranial magnetic stimulation (TMS) has been proposed as an alternative treatment for patients with ASD because of its promising benefits in reducing repetitive behaviors and enhancing executive functions, the use of high-intensity pulses (Hi-TMS) appears to be related to the side effects of the therapy. Low-intensity TMS (Li-TMS) has been partially investigated, but it may have clinical effects on ASD and simultaneously increase treatment safety.

Environmentally cued hatching (ECH) is widespread in animals and requires regulation of hatching mechanisms. Enzymatic digestion of the egg membrane is a common hatching mechanism in vertebrates and invertebrates. In amphibians and fishes, hatching enzymes (HE) are synthesized and released by hatching gland cells (HGC), whose functional ontogeny determines when hatching can occur.

Background: Super-refractory status epilepticus (SRSE) is an extremely serious neurological emergency. Risk factors and mechanisms involved in transition from refractory status epilepticus (RSE) to SRSE are insufficiently studied.

Methods: This was a multicenter retrospective cohort study of consecutive patients diagnosed and treated for RSE at two reference hospital over 5 years in Ecuador.

Epidemiology of colistin resistance mediated by mcr-1 in carbapenemase-producing Enterobacterales in Ecuador in three periods from 2016 to 2022.

Rev Argent Microbiol

January 2025

Department of Microbiology, School of Medicine and PhD Program in Clinical Medicine and Public Health, University of Granada & Ibs, Granada, Spain; Department of Microbiology, Hospital Virgen de las Nieves, Institute for Biosanitary Research-Ibs, Granada, Spain.

Carbapenemase-producing Enterobacterales (CPE) have increased in the last decade. In low-income countries, colistin is considered a last resort antimicrobial to treat CPE infections, whose most worrisome mechanism of resistance is MCR-1 production. This study aims to understand the epidemiology of colistin resistance in CPE in the region, through the surveillance of the mcr-1 gene in CPE isolates in Ecuador.

The presence in ecological communities of unfeasible species interactions, termed forbidden links, due to physiological or morphological exploitation barriers has been long debated, but little direct evidence has been found. Forbidden links are likely to make ecological communities less robust to species extinctions, stressing the need to assess their prevalence. Here, we used a dataset of plant-hummingbird interactions, coupled with a Bayesian hierarchical model, to assess the importance of exploitation barriers in determining species interactions.

Atahualpa is a rural village located in coastal Ecuador, a region that has been inhabited by people as early as 10,000 years ago. The traditional diet of their indigenous inhabitants is rich in oily fish and they have, therefore, served as a model for investigating the beneficial effects of such a diet. However, the genetic background of this population has not been studied.

Laetrile, known as vitamin B17, is often used interchangeably with amygdalin. Laetrile is a semi-synthesis product of amygdalin, whereas amygdalin is a naturally occurring substance in many plants. Both compounds have a nitrile functional group that, when activated by the intestinal enzyme β-glucosidases, releases hydrogen cyanide.

Department of Global Health and Social Medicine, Institute of Gerontology, Faculty of Social Science and Public Policy, King's College London, London, United Kingdom.

Introduction: Osteoporosis is a significant geriatric condition, considering its impact on fracture-related morbidity and mortality, particularly among older women. The interplay of clinical evidence, diagnostic tools availability, and broader societal attitudes toward aging and treatment efficacy affect medical attitude and prescribing behaviors. Using the example of osteoporosis in France and England, the study aims to unravel the intricacies of medical decision-making in geriatric care, offering insights into the evolving landscape of healthcare policy and practice, which in turn can help reduce futile biomedical research.
