As Drumond Rennie put it, ‘Science does not come alive until it is shared publicly’ (1998), emphasising that the rapid advancement of scientific research requires its efficient and rigorous dissemination both to encourage the development of new strategies and to avoid duplication of effort and resources. The current model of scientific and technological research is facing a significant challenge: the cost associated with publishing its results. It is now increasingly common for publishers to impose fees on the scientific community to publish their results, generating debate about the impact of this practice on the fairness of scientific dissemination.

Article Synopsis
  • Demographic rescue involves adding individuals to endangered populations to boost their numbers and prevent extinction, but its effectiveness is uncertain in the presence of diseases.
  • A study was conducted using an aquatic crustacean, Daphnia dentifera, and a fungus pathogen, Metschnikowia bicuspidata, to investigate how pathogens affect demographic rescue outcomes.
  • Results showed that while adding healthy individuals temporarily increased population size, populations with infected individuals ultimately had significantly lower abundance compared to those with no intervention, highlighting the risks of introducing diseased organisms during rescue efforts.*

Introduction: Coronavirus disease 2019 (COVID-19) affects the population unequally, with a greater impact on older and immunosuppressed people.

Methods: Hence, we performed a prospective experimental cohort study to characterise the effect of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination in immune-compromised patients (older adults and oncohaematologic patients), compared with healthy counterparts, based on deep characterisation of the circulating immune cell subsets.

Results And Discussion: While acquired humoral and cellular memory did not predict subsequent infection 18 months after full vaccination, spectral and computational cytometry revealed several subsets within the CD8 T-cells, B-cells, natural killer (NK) cells, monocytes and TEMRA Tγδ cells that were differentially expressed in individuals who were subsequently infected and not infected not just following immunisation, but also prior to vaccination.

Chronic kidney disease (CKD) is a growing health concern, projected to be a major cause of death by 2040, due to an increasing risk of acute kidney injury (AKI). Systems biology-derived data suggest that the unmet need for an orally available drug to treat AKI and improve CKD outcomes may be addressed by targeting kidney inflammation and, specifically, nuclear factor κB-inducing kinase (NIK), a key signaling molecule that activates the noncanonical nuclear factor κB (NF-κB) pathway. We have prepared and identified a small family of imidazolone derivatives that bind NIK and inhibit the noncanonical NF-κB activation pathway.

Several data indicate that Substance P (SP) neurokinin type 1 receptor (NK1R) is at the center of the interaction between cancer cells and peripheral sensory neurons. Selecting the appropriate cancer cell line and its susceptibility to being modulated by NK1 antagonists are critical to studying this complex interaction. In the current study, we have focused on this selection by comparing several aspects of the triple-negative breast cancer (TNBC) cell line (MDA-MB-231) with a modified murine cell line (E0771), both expressing luciferase.

Terpenoids play key roles in cellular metabolism and can have specialized functions. Their heterologous production in microbial hosts offers an alternative to natural extraction. Here, we developed a subcellular engineering approach in the model green alga Chlamydomonas reinhardtii by targeting both sesquiterpenoid synthases and cytochrome P450s (CYPs) to the plastid, exploiting its photosynthetic electron transport chain to drive CYP-mediated oxidation without reductase partners.

Article Synopsis
  • Trichothecenes are toxins from certain fungi that impact plant disease and biological control, and are characterized by a common structure called EPT, with variations in a macrocyclic ring formation.
  • Recent research identified the TRI24 gene as essential for forming this macrocyclic ring in the fungus Paramyrothecium roridum.
  • A mutant strain lacking TRI24 displayed reduced severity in plant disease and antifungal activity, highlighting the significance of the macrocyclic ring in the biological functions of these trichothecenes.

Background: Older adults' psychosocial outcomes during the COVID-19 pandemic have been inequitable by socio-economic status (SES). However, studies have focused solely on own SES, ignoring emerging evidence of the relationship between adult child SES and late-life health. We evaluated whether adult child educational attainment - a core marker of SES - is associated with older parents' psychosocial outcomes during the pandemic.

Article Synopsis
  • Age is often a factor in predicting outcomes for patients with large vessel occlusions treated with mechanical thrombectomy, but there’s limited research on outcomes for octo/nonagenarians compared to younger patients, specifically for acute basilar artery occlusions.
  • A study using data from the PC-SEARCH Thrombectomy Registry analyzed 444 cases, dividing patients into two age groups: those over 80 and those 80 or younger.
  • Results showed that while fewer older patients achieved favorable outcomes at 90 days post-treatment, the differences were not statistically significant after adjusting for other health factors, suggesting that octo/nonagenarians can have comparable functional recovery to younger patients when treated with thrombectomy.

Based on current evidence and established critical thresholds for soil degradation indicators, it is concerning that over 60-70% of European soils are unhealthy due to unsustainable management and the impact of climate change. Despite European and national efforts to improve soil health, significant gaps remain. The proposal for a Soil Monitoring and Resilience Law, to be implemented by the European Union, seeks to establish a framework for soil monitoring and promote sustainable management practices to achieve healthy soils by 2050.

Studies analyzing indoor thermal environments comprising temperature and humidity may be insufficient when obtaining data from sensors, which may be susceptible to inaccurate or failed information from internal and external factors. Therefore, this study proposes an intelligent climate monitoring using a supervised learning method for virtual hygrothermal measurement in enclosed buildings used to predict temperature and relative humidity when a sensor failure is detected. The methodology comprises the data collection from a wireless sensor network, the building of the learning model for predicting the dynamics of environmental variables, and the implementation of a sensor failure detection model.
