The promise of community-driven preprints in ecology and evolution.

Publishing preprints is quickly becoming commonplace in ecology and evolutionary biology. Preprints can facilitate the rapid sharing of scientific knowledge establishing precedence and enabling feedback from the research community before peer review. Yet, significant barriers to preprint use exist, including language barriers, a lack of understanding about the benefits of preprints and a lack of diversity in the types of research outputs accepted (e.

Exploring Dietitians' Experience of Blended Tube Feed in Paediatric Inpatient Settings: National Cross-Sectional Survey, United Kingdom.

Background: Enteral tube feeding is used for children who are unable to meet their nutritional requirements orally. Gastrointestinal symptoms are some complications that can occur in enteral tube-fed patients. Blended tube feeds (BTFs) for children who are gastrotomy tube-fed have significantly increased in the last decade.

Eco-Friendly Synthesis of Selenium Nanoparticles via Sternbergia candida: Enhancing Antioxidant Defense and Mitigating Salt Stress in Pepper (Capsicum annuum L.) Plants.

Selenium mitigates the adverse effects of salinity on plant growth, boosting antioxidant defense, metabolism, and resilience to abiotic stress. Our study applied selenium nanoparticles to mitigate salinity-induced damage and support plant growth.

One-component anti-aging agents.

Polymer photo-oxidation aging is a significant issue in plastics engineering, leading to reduced performance, shorter lifespan, and additional pollution. Anti-aging agents, including antioxidants and ultraviolet (UV)-shielding agents, are used to ameliorate the above problems. However, multi-component agents involve complex synthesis, mixed processing, and environmental concerns.

Proteo-Transcriptomic Analysis Reveals the Mechanisms Underlying Escherichia coli Phenotypic Shifts Under Blue Light.

Bacteria can adapt their lifestyles, including microbial growth, metabolism, and biofilm formation, in response to light signaling. However, the molecular pathways through which blue light affects the lifestyle of Escherichia coli (E. coli) remain incomplete and poorly understood.

Assessment of Commercial Baby Food Quality and Promotion in Malaysia for Policy Development.

Nutritional quality of food for infants and young children (FIYC) is key to optimum development and health. To evaluate commercial FIYC products, the World Health Organization Regional Office for Europe (WHO-EURO) has defined a Nutrient and Promotion Profile Model (NPPM). Although FIYC is commonly used in Malaysia, its quality is largely unknown.

Plant-based eating pattern and psychological symptoms: a cross-sectional survey among patients with migraine.

Objectives: The present study evaluated the association between plant-based diet index (PDI) and psychological symptoms, including depressive symptoms, stress, and anxiety among Iranian women diagnosed with migraine headaches.

Ultra-sensitive fiber optic LSPR biosensor with enhanced enzyme functionalization for real-time putrescine detection.

Putrescine is a kind of physical diamine that is closely related to food deterioration and food quality safety. This study employs a novel fiber optic biosensor based on S-tapered and waist extension techniques, as well as localized surface plasmon resonance (LSPR), to detect putrescine accurately. The gold nanoparticles (AuNPs) are fixed on the fiber to excite LSPR.

How do extreme fluctuations in water level affect fish condition in Amazonian Floodplain Lakes?

The annual flood pulse is a defining feature of Amazonian floodplain lakes, creating a highly variable environment that influences resource availability, such as food and habitat. These cyclical changes necessitate a high degree of adaptability among fish species, many of which have evolved specialized strategies to cope with the fluctuating conditions. In 2023, the Amazon basin experienced a record-breaking drought event, leading to mass mortality of Amazonian fish and other wildlife.

Toward Developing Alternative Opioid Antagonists for Treating Community Overdose: A Model-Based Evaluation of Important Pharmacological Attributes.

In response to increased illicit use of synthetic opioids, various μ-receptor antagonist formulations, with varied pharmacological characteristics, have been and are being developed. To understand how pharmacologic characteristics such as absorption rate and clearance rate affect reversal in treating community opioid overdose, we used our previously published translational opioid model. We adapted this model with in vitro receptor binding data and clinical pharmacokinetic data of three intranasal nalmefene formulations along with an intranasal naloxone formulation to study the reversal of fentanyl and carfentanil-induced respiratory depression in chronic opioid users.

Chewing-Activated TRPV4/PIEZO1--Zn Axes in a Rat Periodontal Complex.

The upstream mechanobiological pathways that regulate the downstream mineralization rates in periodontal tissues are limitedly understood. Herein, we spatially colocalized and correlated compression and tension strain profiles with the expressions of mechanosensory ion channels (MS-ion) TRPV4 and PIEZO1, biometal zinc, mitochondrial function marker (), cell senescence indicator (), and oxygen status marker hypoxia-inducible factor-1α () in rats fed hard and soft foods. The observed zinc and related cellular homeostasis in vivo were ascertained by TRPV4 and PIEZO1 agonists and antagonists on human periodontal ligament fibroblasts ex vivo.

Assembly of collagen fibers into contiguous dense and loose regions of subcutaneous fascia.

Objective: This study aimed to investigate the collagen fiber structure of the subcutaneous fascia, a connective tissue layer between the skin and epimysium.

Methods: Fascia samples with varying extensibility were examined using biochemical and microscopic methods.

Results: Loose fascia, the more extensible type, displayed sparsely distributed collagen fibers, while dense fascia showed tightly packed collagen fiber bundles.

E. Coli cytotoxic necrotizing factor-1 promotes colorectal carcinogenesis by causing oxidative stress, DNA damage and intestinal permeability alteration.

Background: Bacterial toxins are emerging as promising hallmarks of colorectal cancer (CRC) pathogenesis. In particular, Cytotoxic Necrotizing Factor 1 (CNF1) from E. coli deserves special consideration due to the significantly higher prevalence of this toxin gene in CRC patients with respect to healthy subjects, and to the numerous tumor-promoting effects that have been ascribed to the toxin in vitro.

The AhR pathway regulation in phthalates-induced cancer promotion, progression and metastasis: a scoping review.

Background: Cancer remains a leading cause of death worldwide. Environmental factors, specifically endocrine-disrupting chemicals (EDCs), like phthalates, are increasingly being linked to cancer development. Phthalates, widely used in consumer products, can activate the aryl hydrocarbon receptor (AhR).

hERGAT: predicting hERG blockers using graph attention mechanism through atom- and molecule-level interaction analyses.

The human ether-a-go-go-related gene (hERG) channel plays a critical role in the electrical activity of the heart, and its blockers can cause serious cardiotoxic effects. Thus, screening for hERG channel blockers is a crucial step in the drug development process. Many in silico models have been developed to predict hERG blockers, which can efficiently save time and resources.

Rationale and design of APOLLO: a personalized rehAbilitation PrOgram in aLLOgeneic bone marrow transplantation.

Background: Hematopoietic stem cell transplantation (HSCT) is a common therapy for many hematologic malignancies. While advances in transplant practice have improved cancer-specific outcomes, multiple and debilitating long term physical and psychologic effects remain. Patients undergoing allogeneic bone marrow transplantation (allo-BMT) are often critically ill at initial diagnosis and with necessary sequential treatments become increasingly frail and deconditioned.

A new approach for evaluating maize transgressive segregants and their three-way cross potential in the S4 convergent breeding population.

The development of transgressive segregant (TS) selection on convergent breeding populations of S4 maize is a concept that is rarely applied. However, the development of TS is necessary to accelerate maize breeding pipelines. Therefore, the objectives of this study were (1) to develop the concept of TS selection and (2) to select S4 TS maize to be developed as hybrid cross parents.
