The Role of KRAS Mutations in Colorectal Cancer: Biological Insights, Clinical Implications, and Future Therapeutic Perspectives.

: Colorectal cancer (CRC) remains a leading cause of cancer mortality globally, with KRAS mutations occurring in 30-40% of cases, contributing to poor prognosis and resistance to anti-EGFR therapy. This review explores the biological significance, clinical implications, and therapeutic targeting of KRAS mutations in CRC. : A comprehensive analysis of the existing literature and clinical trials was performed, highlighting the role of KRAS mutations in CRC pathogenesis, their impact on prognosis, and recent advancements in targeted therapies.

Water temperature effects on embryonic development and GnRH-like expression in kisslip cuttlefish (Sepia lycidas) hinting the potential role of GnRH-like peptide.

Gonadotropin-releasing hormone (GnRH)-like peptides are multifunctional neuropeptides involved in cardiac control, early ontogenesis, and reproduction in cephalopods. However, the precise role of GnRH-like peptides in embryonic development and juvenile growth in cephalopods remains unknown. In this study, we showed that GnRH-like peptides are involved in the embryonic development of kisslip cuttlefish (Sepia lycidas).

[A Case of Early Appendiceal Adenocarcinoma Coexisting with High-Grade Appendiceal Mucinous Neoplasm].

We report a case of a female in her fifties with early appendiceal adenocarcinoma coexisting with high-grade appendiceal mucinous neoplasm(HAMN)with a review of the literature. The patient presented to our hospital because of an enlarged appendix noted by contrast-enhanced CT performed for hematuria. Contrast-enhanced CT showed that the appendix had swollen to 10 mm and mucus had accumulated inside, which had no evidence of obvious malignancy.

[A Case of Locally Advanced Appendiceal Cancer with Radical Resection after CAPOX plus Bevacizumab].

We report a case of a male in his sixties with appendiceal cancer who underwent radical resection following CAPOX plus bevacizumab neoadjuvant chemotherapy. The patient presented to our hospital with a chief complaint of chronic low abdominal pain. Contrast-enhanced CT before neoadjuvant chemotherapy revealed an inhomogeneous tumor in the ileocecal region.

Activation of Supraoptic Oxytocin Neurons by Secretin Facilitates Social Recognition.

Background: Social recognition underlies social behavior in animals, and patients with psychiatric disorders associated with social deficits show abnormalities in social recognition. Oxytocin is implicated in social behavior and has received attention as an effective treatment for sociobehavioral deficits. Secretin receptor-deficient mice show deficits in social behavior.
