The anti-inflammatory properties of mesenchymal stem cells in epilepsy: possible treatments and future perspectives

Mesenchymal stem cells (MSCs) are multipotent adult cells with self-renewing capacities. MSCs display specific properties, such as the ability to repair damaged tissues, resulting in optimal candidates for cell therapy against degenerative diseases. In addition to the reparative functions of MSCs, growing evidence shows that these cells have potent immunomodulatory and anti-inflammatory properties. Therefore, MSCs are potential tools for treating inflammation-related neurological diseases, including epilepsy. In this regard, over the last decades, epilepsy has no longer been considered a purely neuronal pathology, since inflammatory events underlying the genesis of epilepsy have been demonstrated. This review assessed current knowledge on the use of MSCs in the treatment of epilepsy. Mostly, attention will be focused on the anti-inflammatory and immunological skills of MSCs. Understanding the mechanisms by which MSCs might modulate the severity of the disease will contribute to the development of new potential alternatives for both prophylaxis and treatment against epilepsy

Genetic diversity of dinitrogen-fixing bacterial communities in soil amended with olive husks

The industrial production of olive oil is accompanied by the accumulation of large quantities of by-products from the olive milling industry that are commonly dispersed as fertilisers, which are nowadays suspected to have potential toxic effects on is omicroflora. The aim of this work has been the investigation of the genetic diversity of bacterial communities present in soil treated with olive husks focusing on the dinitrogen-fixing bacteria.nifH genes were amplified from total soil DNA using universal primers, cloned and typed by restriction analysis and sequencing of representative haplotypes. On the same samples, DGGE analysis on amplified 16S rDNA was performed aiming at monitoring modifications in the total community pattern. Results showed a high genetic diversity ofnifH genes within the community, which was well in agreement with the total community profiles obtained by DGGE on 16SrDNA. Most of thenifH gene fragments (19 out of 32) were found to be similar to sequences related with clostridia

Gut microbiota modulates seizure susceptibility

A bulk of data suggest that the gut microbiota plays a role in a broad range of diseases, including those affecting the central nervous system. Recently, significant differences in the intestinal microbiota of patients with epilepsy, compared to healthy volunteers, have been reported in an observational study. However, an active role of the intestinal microbiota in the pathogenesis of epilepsy, through the so-called "gut-brain axis," has yet to be demonstrated. In this study, we evaluated the direct impact of microbiota transplanted from epileptic animals to healthy recipient animals, to clarify whether the microbiota from animals with epilepsy can affect the excitability of the recipients' brain by lowering seizure thresholds. Our results provide the first evidence that mice who received microbiota from epileptic animals are more prone to develop status epilepticus, compared to recipients of "healthy" microbiota, after a subclinical dose of pilocarpine, indicating a higher susceptibility to seizures. The lower thresholds for seizure activity found in this study support the hypothesis that the microbiota, through the gut-brain axis, is able to affect neuronal excitability in the brain

Mapping stakeholders to maximise the impact of research on health inequalities for people with learning disabilities: the development of a framework for the Making Positive Moves study

© 2024 The Authors. British Journal of Learning Disabilities published by John Wiley & Sons Ltd. This is an open access article distributed under the terms of the Creative Commons Attribution License (CC BY), https://creativecommons.org/licenses/by/4.0/Background: People with learning disabilities experience health and social inequalities, and research that could improve health services may not be implemented in real‐life settings. Building stakeholder networks that can share and implement research findings may address this. This paper presents a framework for building a stakeholder network that maximises the likelihood of research recommendations being implemented in practice. This was developed as part of the ‘Making Positive Moves’ (MPM) study, which explores the experiences of people with learning disabilities following discharge from a residential stay within a hospital inpatient setting. Methods: We reviewed the literature on existing theoretical frameworks to support the development of a model for dissemination of the MPM findings. Stakeholder categories were identified through consultation with the MPM researchers, experts by experience and the steering group and a hub and spoke model to represent all stakeholder categories was created. These categories include person moving; family of the person moving; specialist schools; social care; care providers; regulators; third sector organisations; policy organisations; academic community; and NHS professionals. After establishing the categories, we consulted with people with learning disabilities and other stakeholders and conducted online searches to create a stakeholder database. Through information gathering and direct contact with stakeholders, we assessed levels of interest, power and engagement to determine which stakeholders to prioritise in our dissemination activities. The Stakeholder Wheel was created to present the data captured within the database and engagement profiles in an illustrative way. Findings: We use two stakeholder sub‐categories, user‐led organisations and care providers, to demonstrate the methodological approach. The examples illustrate how a scoring system helped us to identify high‐priority stakeholders who we then contacted to collaborate within developing our dissemination strategy to maximise the impact of the MPM research findings. Conclusions: We developed a framework to map stakeholders for the MPM study and enable targeted dissemination to increase the impact of the research. This approach has the potential to reduce health inequalities among people with learning disabilities by increasing the awareness of and ability to implement evidence‐based recommendations in real‐life settings. The stakeholder mapping framework could be applied to research projects associated with learning disabilities to bridge the gap between research and practice and reduce health inequalities.Peer reviewe

Measurement of the 244^{244}Cm and 246^{246}Cm Neutron-Induced Cross Sections at the n_TOF Facility

The neutron capture reactions of the $^{244}$Cm and $^{246}$Cm isotopes open the path for the formation of heavier Cm isotopes and of heavier elements such as Bk and Cf in a nuclear reactor. In addition, both isotopes belong to the minor actinides with a large contribution to the decay heat and to the neutron emission in irradiated fuels proposed for the transmutation of nuclear waste and fast critical reactors. The available experimental data for both isotopes are very scarce. We measured the neutron capture cross section with isotopically enriched samples of $^{244}$Cm and $^{246}$Cm provided by JAEA. The measurement covers the range from 1 eV to 250 eV in the n_TOF Experimental Area 2 (EAR-2). In addition, a normalization measurement with the $^{244}$Cm sample was performed at Experimental Area 1 (EAR-1) with the Total Absorption Calorimeter (TAC)

Synthetic plant microbiota challenges in nonmodel species

Plant-associated microbiota are becoming central in the development of ways to improve plant productivity and health. However, most research has focussed mainly on a few model plant species. It is essential to translate discoveries to the many nonmodel crops, allowing the design and application of effective synthetic microbiota
