The Romans were among the first societies to extensively exploit fish resources, establishing large-scale salting and preservation plants where small pelagic fish were fermented to produce sauces such as garum. Here, the authors demonstrate that, despite being crushed and exposed to acidic conditions, usable DNA can be recovered from ichthyological residues at the bottom of fish-salting vats. At third-century AD Adro Vello (O Grove), Galicia, they confirm the use of European sardines (Sardina pilchardus) and move beyond morphology to explore population range and admixture and reveal the potential of this overlooked archaeological resource.

Toxoplasmosis, caused by the obligate intracellular parasite Toxoplasma gondii, is one of the most prevalent zoonotic parasitic infections worldwide. When acquired during pregnancy, T. gondii can be transmitted to the fetus, with clinical outcomes influenced by gestational age at time of infection and the parasite’s genotype. Prenatal screening enables the detection of maternal seroconversion and offers a critical window for intervention. In Uruguay, despite mandatory serological screening during pregnancy, national data on T. gondii seroprevalence and maternal seroconversion have not been updated in two decades. In addition, the genetic diversity of local strains remains poorly characterized. In this study, we analysed publicly available serological data from pregnant individuals attending Uruguay’s largest public maternity hospital between 2019 and 2023. We found that seroprevalence has modestly declined from 50% (reported in 1998) to 45.5%, with a congenital transmission rate of 0.58%. Clinical analysis of affected newborns revealed chorioretinitis as the predominant manifestation. To investigate parasite diversity, we performed genotyping of T. gondii strains using in silico PCR-RFLP following molecular detection. Our findings revealed substantial genetic diversity, including novel allele combinations not previously described in the region. These results highlight both the continued public health burden and the evolving genetic landscape of T. gondii in Uruguay. Our findings underscore the need to strengthen surveillance and prevention strategies for congenital toxoplasmosis in South America.

Livestock farming is currently highly questioned and is considered by society to be one of the main precursors of climate change and innumerable environmental impacts. This social concern has marked a trend in public policies in Europe, promoting strategies to reduce greenhouse gas (GHG) emissions by controlling the carbon footprint of agri-food products. However, in certain regions, the perception of the main actors in the sector about the role that livestock farming plays in this fight against climate change and how new political trends point the way toward the sustainability of agrarian systems is still uncertain. In this study, the opinions of stakeholders of the agro-livestock sector on the role that extensive livestock farming plays in the current context of the fight against climate change and the demands for public policies to facilitate the adoption of mitigation practices were examined. A participatory research process through focus groups was used in this qualitative study. Specifically, five sessions were held at the beginning of 2022; the sessions were recorded, transcribed, and anonymized for further analysis. In these sessions, projective techniques were used, such as word association and sentence completion to understand stakeholders' perceptions of the role of extensive livestock farming in climate change. Brand mapping was conducted to determine the opinion on the profitability and GHG emissions of 10 livestock systems typical of the region and of eight quality labelling systems related to sustainability. Brainstorming was carried out to assess available practices for the adaptation of livestock farms and mitigation of climate change. Finally, there was an open debate regarding the demands for public aid for the implementation of mitigation practices. The word association technique identified concepts such as ‘Equilibrium’ in extensive livestock farming and concepts such as ‘Effects’, ‘Action’ and ‘Concern’ in climate change. For the term carbon footprint, the most mentioned concept was ‘ignorance’, and for common agricultural policy, the most mentioned term was ‘injustices’. The results of the brand mapping allowed us to determine the perception of the stakeholders regarding the profitability of the different extensive farm systems and on their GHG emissions, with the most extensive and traditional ones being perceived as the lowest emitters of gases but also the least profitable. For sustainable labels, stakeholders believed that labels contribute to profitability and lower GHG emissions. Strategies to adapt to climate change and reduce the impact of farms were focused on reforestation, grazing, and soil management, adjusting the livestock stocking rate and self-production of food on farms. The best mitigating practices proposed were the maintenance of the extensive livestock farming (4.69), improvement of accesses, livestock routes and roads (4.63), making and applying compost (4.50) and the simplified administrative procedures (5.00). In the prioritization of public aids, three categories were established based on the field of action: social/organizational measures (38 votes), economic measures (44 votes) and environmental measures (22 votes). The aid related to maintaining profitability and improving marketing, followed by aid to reduce bureaucracy and direct aid to extensive livestock farming, were identified as priorities. This study offers a detailed picture of how stakeholders in the agro-livestock sector see the role that extensive livestock farming plays in the fight against climate change. The best farm management practices and priority lines of public support that policy-makers can apply have been identified in this study and emanate directly from those who receive subsidies and make the decisions in their livestock farming to ensure their implementation more successful.

The Guillain-Barré syndrome (GBS) has been previously associated with Zika virus infection. We analysed the data from all the patients with GBS diagnosis that were admitted to a referral hospital, in Tapachula City during the period from January 2013 to August 2016, comparing the incidence of GBS according to the temporality of the Zika outbreak in Southern Mexico. Additionally, we described the clinical and epidemiological characteristics of the GBS patients admitted before or after the Zika outbreak. We observed a sharp increase in the number of patients hospitalised due to GBS from the time the first confirmed Zika cases appeared in Mexico. Clinically we observed GBS cases before zika outbreak had more frequently history of respiratory/gastrointestinal symptoms and GBS during zika outbreak had significantly more frequently recent history of rash/conjunctivitis. Although we cannot affirm that the increased cases of GBS have a specific aetiologic association with Zika, our results suggest that this observed outbreak of in Tapachula, might have been associated to the emerging Zika epidemic, locally and suggests that rare complications associated with acute infections (such as GBS) might be useful in the surveillance systems for emerging infections.

Phrasal verbs (e.g. fade away, give up) tend to be associated with spoken, colloquial registers, not only in Present-day English, but also in previous stages of the language. This view has recently been challenged by Thim's (2006a, 2012) ‘colloquialization conspiracy’, according to which the idea that phrasal verbs are colloquial is based on a misconception which first arose in the eighteenth century. In the current study we seek to verify Thim's claim by exploring phrasal verbs in A Corpus of English Dialogues 1560–1760, a 1.2-million-word corpus of Early Modern English (EModE) speech-related text types. Based on a sample of over 7,000 examples, we demonstrate that the linguistic features, distribution and high productivity of phrasal verbs in the EModE period point towards a full entrenchment of these combinations in the spoken language, which leads us to the conclusion that the colloquial status of phrasal verbs in EModE is not merely a matter of a ‘colloquialization conspiracy’.

The verb to like has fallen repeatedly under the gaze of scholars. One aspect which has stimulated vigorous discussion is its original use in impersonal constructions and its later change of argument structure along with the disappearance of impersonals from English. Nonetheless, evidence from current informal English shows that like is now used in constructions which bear a close resemblance to the older impersonals, although always displaying alternative spelling variants, especially likey. This paper seeks to further our understanding of the verb to like, focusing specifically on these new constructions. To this end I will use likey as a generic label to refer to such new uses and constructions, regardless of variations in spelling (unless otherwise stated). Using data from the Corpus of Historical American English and iWeb Corpus, the study will seek to answer the following research questions:

1. RQ1. What are the morpho-syntactic features of the expression ‘me (no) likey’ in Present-Day English?

2. RQ2. What is the origin of the sequence ‘me (no) likey’?

3. RQ3. Where do phrasal patterns with likey fall on the continuum of idiomaticity (Michaelis, 2017)?

Olive oil and wine are consumed daily worldwide, and they constitute the fundamental pillars of the healthy Mediterranean diet. Polyphenolic compounds, naturally present in both olive oil and wine, are responsible for their beneficial properties. Current studies have shown the neuroprotective effects of polyphenols independently of their well-known antioxidant action. In this work, we have focused on reviewing the protective effect of polyphenols from extra virgin olive oil and wine in Alzheimer´s disease (AD), to emphasise that both foods could be a possible therapeutic tool. Beneficial effects have been described in β-aggregation, neurofibrillary tangles, autophagy and mitochondrial function, as well as in cerebral insulin resistance. Furthermore, to date, a harmful dose has not been described. Both pre-clinical and clinical works demonstrate that polyphenols act on neuropathological and cognitive disorders of AD, preventing or stopping the onset of this devastating disease. However, there are certain limitations in these studies, since it is very difficult to research diseases that lead to cognitive impairment. Although all the findings obtained are very encouraging, more studies should be carried out investigating the use of the polyphenols from olive oil and wine as therapeutic agents in the progression of AD. Therefore, more longitudinal studies in humans with a homogeneous cohort of patients are necessary to corroborate the efficacy of these nutraceuticals, as well as determine the most appropriate dose for this purpose.

The present study evaluated the effect of binder of sperm protein 1 (BSP1) and/or heparin on in vitro bovine capacitation and fertilization rates using epididymal and ejaculated bovine sperm. Frozen–thawed sperm were selected and used in the following treatments. Control group: Fert-TALP medium without heparin; heparin (HEP) group: Fert-TALP with heparin (10 UI/ml); BSP1 group: Fert-TALP medium with BSP1 (10 µg/ml for ejaculated sperm; 40 µg/ml for epididymal sperm); HEP + BSP1 group: Fert-TALP medium with heparin (5 UI/ml) and BSP1 (5 µg/ml for ejaculated sperm; 20 µg/ml for epididymal sperm) and determined in vitro capacitation rates in different interval times (0, 15, 30 and 60 min) using the chlortetracycline fluorescence (CTC) method. Also, we evaluated the development rates of oocytes fertilized with ejaculated or epididymal sperm into the same treatments. Capacitation was greater and faster when ejaculated sperm were treated for 60 min with heparin compared with other treatments. However, developmental rates were similar in all treatments. For epididymal sperm, the treatments with BSP1 presented higher capacitation and fertilization rates compared with heparin (P < 0.05). The effects of heparin + BSP1 on capacitation and developmental rates did not cause any increase in capacitation or blastocyst rates compared with other groups for ejaculated or epididymal sperm. In conclusion, this study confirmed that either BSP1 and heparin can be used as capacitator agents for bovine ejaculated sperm during IVF. However, BSP1 seems to be more efficient compared with heparin for epididymal sperm. Furthermore, BSP1 and heparin have no synergic effects on sperm capacitation.

We consider Stavskaya’s process, which is a two-state probabilistic cellular automaton defined on a one-dimensional lattice. The state of any vertex depends only on itself and on the state of its right-adjacent neighbour. This process was one of the first multicomponent systems with local interaction for which the existence of a kind of phase transition has been rigorously proved. However, the exact localisation of its critical value remains as an open problem. We provide a new lower bound for the critical value.

The aim of this study was to evaluate the effects of alternative protocols to improve oocyte selection, embryo activation and genomic reprogramming on in vitro development of porcine embryos cloned by somatic cell nuclear transfer (SCNT). In Experiment 1, in vitro-matured oocytes were selected by exposure to a hyperosmotic sucrose solution prior to micromanipulation. In Experiment 2, an alternative chemical activation protocol using a zinc chelator as an adjuvant (ionomycin + N,N,N′,N′-tetrakis(2-pyridylmethyl)ethylenediamine (TPEN) + N-6-dimethylaminopurine (6-DMAP)) was compared with a standard protocol (ionomycin + 6-DMAP) for the activation of porcine oocytes or SCNT embryos. In Experiment 3, presumptive cloned zygotes were incubated after chemical activation in a histone deacetylase inhibitor (Scriptaid) for 15 h, with the evaluation of embryo yield and total cell number in day 7 blastocysts. In Experiment 1, cleavage rates tended to be higher in sucrose-treated oocytes than controls (123/199, 61.8% vs. 119/222, 53.6%, respectively); however, blastocyst rates were similar between groups. In Experiment 2, cleavage rates were higher in zygotes treated with TPEN than controls but no difference in blastocyst rates between groups occurred. For Experiment 3, the exposure to Scriptaid did not improve embryo development after cloning. Nevertheless, the total number of cells was higher in cloned zygotes treated with Scriptaid than SCNT controls. In conclusion, oocyte selection by sucrose as well as treatments with zinc chelator and an inhibitor of histone deacetylases did not significantly improve blastocyst yield in cloned and parthenotes. However, the histone deacetylases inhibitor produced a significant improvement in the blastocyst quality.

A primary barrier to translation of clinical research discoveries into care delivery and population health is the lack of sustainable infrastructure bringing researchers, policymakers, practitioners, and communities together to reduce silos in knowledge and action. As National Institutes of Healthʼs (NIH) mechanism to advance translational research, Clinical and Translational Science Award (CTSA) awardees are uniquely positioned to bridge this gap. Delivering on this promise requires sustained collaboration and alignment between research institutions and public health and healthcare programs and services. We describe the collaboration of seven CTSA hubs with city, county, and state healthcare and public health organizations striving to realize this vision together. Partnership representatives convened monthly to identify key components, common and unique themes, and barriers in academic–public collaborations. All partnerships aligned the activities of the CTSA programs with the needs of the city/county/state partners, by sharing resources, responding to real-time policy questions and training needs, promoting best practices, and advancing community-engaged research, and dissemination and implementation science to narrow the knowledge-to-practice gap. Barriers included competing priorities, differing timelines, bureaucratic hurdles, and unstable funding. Academic–public health/health system partnerships represent a unique and underutilized model with potential to enhance community and population health.
