Background: Peritoneal dissemination of ovarian cancer (OvCa) can be largely attributed to the formation of a metastatic microenvironment driven by tumoral exosomes. Here, we aimed to elucidate the mechanisms through which exosomal annexin A2 (ANXA2) derived from OvCa cells induces an HPMC phenotypic shift in favour of peritoneal metastasis.
Methods: Immunohistochemistry and orthotopic and intraperitoneal OvCa xenograft mouse models were used to clarify the relationship between tumour ANXA2 expression and peritoneal metastasis.
Background: Deep sowing has emerged as a vital agricultural strategy, particularly in arid and semi-arid regions, as it allows seeds to access water stored in deeper soil layers. This approach facilitates successful germination and establishment of crops, even in challenging environmental conditions. Previous studies have shown that the length of the maize mesocotyl is an important trait influencing deep-sowing tolerance.

However, achieving an effective and durable bond with enamel is challenging because of its chemical inertness and low surface energy, and data on the effects of different surface treatments on the durability of PEEK-enamel bonds are scarce.
Purpose: The purpose of this in vitro study was to investigate airborne-particle abrasion, sulfuric acid etching, and the combined use of these treatments on the bonding durability of PEEK-enamel bonds and to gain a deeper understanding of their bonding mechanism.
Aims: Chronic pain is a critical public health issue that severely impacts quality of life and poses significant treatment challenges, particularly due to the risk of adverse effects associated with pharmacological therapies. The search for effective non-invasive treatment alternatives has become increasingly relevant. Low-intensity focused ultrasound (LIFU) has been identified as an effective non-invasive strategy for pain management, although the underlying mechanism remains unclear.
