Metformin-based nanomedicines for reprogramming tumor immune microenvironment.

Immunotherapy has transformed current cancer management, and it has achieved significant progress over last decades. However, an immunosuppressive tumor microenvironment (TME) diminishes the effectiveness of immunotherapy by suppressing the activity of immune cells and facilitating tumor immune-evasion. Adenosine monophosphate-activated protein kinase (AMPK), a key modulator of cellular energy metabolism and homeostasis, has gained growing attention in anti-tumor immunity.

A dual thermo/pH-sensitive hydrogel as 5-Fluorouracil carrier for breast cancer treatment.

Intelligent hydrogels are promising in constructing scaffolds for the controlled delivery of drugs. Here, a dual thermo- and pH-responsive hydrogel called PCG [poly (N-isopropyl acrylamide-co-itaconic acid)/chitosan/glycerophosphate (PNI/CS/GP)] was established as the carrier of 5-fluorouracil (5-FU) for triple-negative breast cancer (TNBC) treatment. The PCG hydrogel was fabricated by blending synthesized [poly (N-isopropyl acrylamide-co-itaconic acid), pNIAAm-co-IA, PNI] with CS in the presence of GP as a crosslinking agent.

Salidroside: An Overview of Its Promising Potential and Diverse Applications.

Salidroside, a phenolic compound isolated from various plants, is the principal active constituent of Traditional Chinese Medicine known for its adaptogenic properties. Due to the challenging environment of species, such as high altitude, high radiation, drought, and hypoxia, the source of salidroside is scarce. However, numerous studies have shown that salidroside has a range of biological activities, including cardiovascular and central nervous system activity, and anti-hypoxia, anti-inflammatory, and anti-aging activities.

Functional Role of Odorant-Binding Proteins in Response to Sex Pheromone Component 8-14:Ac in (Busck).

The plum fruit moth (PFM), , and the oriental fruit moth (OFM), , are closely related fruit moth species that severely damage fruit trees in Rosaceae. Both species share common primary sex pheromone components 8-12:Ac and 8-12:Ac. The secondary sex pheromone components of PFMs consist of 8-12:OH, 8-14:Ac, and 10-14:Ac, while those of OFMs include 8-12:OH and 12:OH.

Fear Generalization Towards a Stimulus and Context and the Impact of Attention Bias.

Fear overgeneralization is a prevalent clinical symptom of anxiety disorders. Various research studies have demonstrated that attention plays a crucial role in fear generalization. Moreover, fear is not only generalized to the stimulus, but individuals may also exhibit a certain degree of fear generalization to the context.
