Science is integral to society because it can inform individual, government, corporate, and civil society decision-making on issues such as public health, new technologies or climate change. Yet, public distrust and populist sentiment challenge the relationship between science and society. To help researchers analyse the science-society nexus across different geographical and cultural contexts, we undertook a cross-sectional population survey resulting in a dataset of 71,922 participants in 68 countries.

Technological advancements have allowed the detection of increasingly complex forensic genetics samples, as minimum amounts of DNA can now be detected in crime scenes or other settings of interest. The weight of the evidence depends on several parameters regarding the population and sample-related analytical factors, the latter in a greater number when the DNA amount is considered. This led to the development of probabilistic genotyping software (PGS), able to deal with the associated complexities.

Objective: Despite lack of evidence supporting efficacy, prophylactic fresh frozen plasma and Octaplas transfusions may be administered to very preterm infants to reduce bleeding risk. International variation in plasma transfusion practices in neonatal intensive care units (NICUs) is poorly understood, therefore, we aimed to describe neonatal plasma transfusion practice in Europe.
Design: Prospective observational study.

Introduction: The ESC and ACC/AHA regularly publish guidelines for the management of cardiovascular disease. By definition, a guideline should follow strict methodological criteria, and have a transparent, traceable and reproducible development process. We aimed to assess the overall strength of the recommendations and rigour of methodological development in ESC and ACC/AHA guidelines.

Interferon-γ (IFN-γ) is a key mediator in antitumor immunity and immunotherapy responses, yet its clinical application remains restricted to chronic granulomatous disease and malignant osteopetrosis. IFN-γ effectiveness as a standalone treatment has shown limited success in clinical trials and its potential for synergistic effects when combined with immunotherapies is under clinical exploration. A particularly compelling combination is that of IFN-γ with Toll-like receptor (TLR) agonists that holds significant promise for cancer treatment.

Metabolic syndrome (MetS) has been associated with disruptions in tissue mechanical homeostasis and inflammatory and metabolic derangements. However, the direct correlation between metabolic alterations and changes in tissue stiffness, and whether they could play a role as upstream initiators of disease pathology remains to be investigated. This emerging concept has yet to be put into clinical practice as many questions concerning the interplay between extracellular matrix mechanical properties and regulation of metabolic pathways remain unsolved.

Background: A small number of reviews have explored lower- versus higher-volume training in non-athletes, but the growing challenge of congested schedules in team sports highlights the need to synthesize evidence specific to team sport athletes. Thus, the objectives of this systematic review with meta-analysis are twofold: (i) to summarize the primary physiological and physical fitness outcomes of lower-volume versus higher-volume training interventions in team sports players; and (ii) to compare the effects of lower-volume training with higher, considering the training modalities used.
Methods: We conducted searches across key databases, including PubMed, Scopus, SPORTDiscus, and Web of Science.

Introduction: Preterm birth remains a global health challenge with significant perinatal morbidity and mortality rates. Despite extensive research, the underlying mechanisms triggering preterm birth remain elusive, needing a deeper understanding of cervical cellular remodelling processes.
Purpose: This study aims to elucidate the cellular mechanisms underlying cervical remodelling in spontaneous preterm labour (PTL) compared to term labour (TL), focusing on the roles of inflammatory cells and fibroblasts.

Thiamin, an essential micronutrient, is a cofactor for enzymes involved in the central carbon metabolism and amino acids pathways. Despite efforts to enhance thiamin content in rice by incorporating thiamin biosynthetic genes, increasing thiamin content in endosperm remains challenging, possibly due to a lack of thiamin stability and/or a local sink. The introduction of storage proteins has been successful in biofortification strategies and similar efforts targeting thiamin led to a 3-4-fold increase in white rice.

Pancreatic panniculitis is a rare dermatological manifestation of pancreatic disorders, characterized by painful, erythematous nodules. We present the case of an 84-year-old woman with acute pancreatitis who developed erythematous-violaceous nodular lesions on her lower limbs. Histopathological examination revealed lobular panniculitis with fat necrosis and ghost adipocytes, confirming the diagnosis.

Here, we present multidisciplinary evidence from Engaji Nanyori in Tanzania's Oldupai Gorge, revealing that thrived in hyperarid landscapes one million years ago. Using biogeochemical analyses, precise chronometric dating, palaeoclimate simulations, biome modeling, fire history reconstructions, palaeobotanical studies, faunal assemblages, and archeological evidence, we reconstruct an environment dominated by semidesert shrubland.

Background: Red Blood Cell Exchange (RBCX) is a common treatment for pediatric sickle cell disease (SCD). Since inflammation with elevated proinflammatory cytokines plays a crucial role in SCD, this study hypothesized that RBCX might lower these cytokines and aimed to assess the impact of this technique on these markers.
Methods: Prospective and observational study of pediatric SCD patients (HbSS genotype) enrolled in a chronic RBCX program at a Portuguese Hospital from October 2022 to August 2024.

Aim: To quantify and compare longitudinal thickness changes of the ganglion cell complex (GCC) and the choroid in patients with different patterns of age-related macular degeneration (AMD) progression.
Methods: Retrospective cohort analysis of anonymized data from participants aged 50y or more and diagnosed with early/intermediate AMD in at least one eye (with no evidence of advanced AMD). A total of 64 participants were included from the Instituto de Retina de Lisboa (IRL) study (IPL/2022/MetAllAMD_ESTeSL) and divided into 4 groups according to the Rotterdam classification for AMD.

Sporopollenin is a plant polymer present in the exine of the pollen grains that comprises two layers: the endexine and the ektexine. It possesses remarkable mechanical, thermal, and chemical stability and is also highly recalcitrant to hydrolysis. The chemical backbone of sporopollenin mostly consists of a polyhydroxylated aliphatic component and polyketide-derived aliphatic α-pyrone elements.

Objective: The objective of this guidance paper is to describe data transformation involving qualitization, including when and how to undertake this process, and to clarify how it aligns with data extraction in order to expand on the current guidance for JBI convergent integrated mixed methods systematic reviews (MMSRs).
Introduction: The convergent integrated approach to MMSRs involves combining extracted data from both quantitative studies (including the quantitative components of mixed methods studies) and qualitative studies (including the qualitative components of mixed methods studies). This process requires data transformation, which can occur either by converting qualitative data into quantitative data (ie, quantitizing) or converting quantitative data into qualitative data (ie, qualitizing).

Beneficial properties of different natural antimicrobials are topics of scientific curiosity for improving safety and extending the shelf life of food commodities. In this regard, phenolic compounds, natural molecules known for their antioxidant, anti-inflammatory, and antimicrobial properties can be right choice. Moreover, bacteriocins, antimicrobial peptides produced by various microorganisms, capable of inhibiting the growth of other bacteria, particularly closely related species can be genuine alternative.

Efficient charge separation at the semiconductor/cocatalyst interface is crucial for high-performance photoelectrodes, as it directly influences the availability of surface charges for solar water oxidation. However, establishing strong molecular-level connections between these interfaces to achieve superior interfacial quality presents significant challenges. This study introduces an innovative electrochemical etching method that generates a high concentration of oxygen vacancy sites on BiVO surfaces (Ov-BiVO), enabling interactions with the oxygen-rich ligands of MIL-101.
