• Phenotypic and genomic characterization of Levilactobacillus brevis YT108: a potential probiotic strain capable of metabolizing xylo-oligosaccharides 29/01/2025
  Levilactobacillus brevis YT108, identified for its ability to metabolize prebiotic xylo-oligosaccharides (XOS), emerges as a candidate for probiotic use in synbiotic food formulations. This study aimed to investigate the metabolic and genomic traits associated with XOS metabolism in YT108 and to assess its probiotic attributes through whole genome sequencing and in vitro assays. Strain YT108 […]

• Hawkmoth pheromone transduction involves G protein-dependent phospholipase Cβ signaling 29/01/2025
  Evolutionary pressures adapted insect chemosensation to the respective insect's physiological needs and tasks in their ecological niches. Solitary nocturnal moths rely on their acute olfactory sense to find mates at night. Pheromones are detected with maximized sensitivity and high temporal resolution through mechanisms that are mostly unknown. While the inverse topology of insect olfactory receptors […]

• Investigate physiological and psychological responses to environment scenes, elements and components in different urban settings 29/01/2025
  Research has proved a close relationship between environments and physiological as well as psychological responses. However, existing research based on neuroscience experiments demonstrated a clear dichotomy between natural and built environments in the selection of exposure settings. There is very limited research analyzing and comparing the effects of different urban environments on individual psychological health. […]

• Salicylic acid confers cadmium tolerance in wheat by regulating photosynthesis, yield and ionic homeostasis 29/01/2025
  Wheat (Triticum aestivum L.) productivity and quality can be threatened by soil cadmium (Cd) contamination, posing a concern to food security. Salicylic acid (SA) is an endogenously produced signaling molecule that activates the defense system imparting abiotic stress tolerance in plants. Hence, an experiment was conducted to explore the roles of foliar application of SA […]

• Variable stressor exposure shapes fitness within and across generations 29/01/2025
  Environmental variation has long been considered a key driver of evolutionary change, predicted to shape different strategies, such as genetic specialization, plasticity, or bet-hedging to maintain fitness. However, little evidence is available with regards to how the periodicity of stressors may impact fitness across generations. To address this gap, I conducted a reciprocal split-brood experiment […]

• A comparison of force adaptation in toddlers and adults during a drawer opening task 29/01/2025
  Adapting movements to rapidly changing conditions is fundamental for interacting with our dynamic environment. This adaptability relies on internal models that predict and evaluate sensory outcomes to adjust motor commands. Even infants anticipate object properties for efficient grasping, suggesting the use of internal models. However, how internal models are adapted in early childhood remains largely […]

• Role of PGC-1α in the proliferation and metastasis of malignant tumors 29/01/2025
  Malignant tumors are among the major diseases threatening human survival in the world, and advancements in medical technology have led to a steady increase in their detection rates worldwide. Despite unique clinical presentations across the spectrum of malignancies, treatment modalities generally adhere to common strategies, encompassing primarily surgical intervention, radiation therapy, chemotherapy, and targeted treatments.

• The Role of Gut Microbiota in Shaping Immune Responses in Tephritidae Fruit Fly and Prospective Implications for Management 29/01/2025
  The interaction of microbial communities with host immunity has become one of the most explored research areas with significant implications for pest control strategies. It has been found that the gut microbiota plays substantial roles in immune response regulation and host-gut microbiome symbiosis, as well as in pathogen resistance and overall fitness in Tephritidae fruit […]

• The impact of climate change on vulnerable populations in pediatrics: opportunities for AI, digital health, and beyond-a scoping review and selected case studies 29/01/2025
  Climate change critically impacts global pediatric health, presenting unique and escalating challenges due to children's inherent vulnerabilities and ongoing physiological development. This scoping review intricately intertwines the spheres of climate change, pediatric health, and Artificial Intelligence (AI), with a goal to elucidate the potential of AI and digital health in mitigating the adverse child health […]

• Accuracy of remote, video-based supraventricular tachycardia detection in patients undergoing elective electrical cardioversion: a prospective cohort 29/01/2025
  Unobtrusive pulse rate monitoring by continuous video recording, based on remote photoplethysmography (rPPG), might enable early detection of perioperative arrhythmias in general ward patients. However, the accuracy of an rPPG-based machine learning model to monitor the pulse rate during sinus rhythm and arrhythmias is unknown. We conducted a prospective, observational diagnostic study in a cohort […]
