Discriminative stimulus properties of α-ethyltryptamine (α-ET) in rats: α-ET-like effects of MDMA, MDA and aryl-monomethoxy substituted derivatives of α-ET.

Rationale α-ET (α-ethyltryptamine), a homolog of the classical hallucinogen α-methyltryptamine, was once prescribed clinically as an antidepressant. Classical psychedelic drugs are currently of interest as potential pharmacotherapy for psychiatric disorders. Objectives Drug discrimination was used to (a) determine if α-ET-like stimulus effects could be engendered by the prototypical phenylalkylamines MDMA ("Ecstasy") or MDA ("Love Drug") and (b) evaluate the α-ET-like stimulus effects of four synthesized aryl-substituted monomethoxy analogs of α-ET (4-OMe-, 5-OMe-, 6-OMe- and 7-OMe-α-ET).

Combine Surgery and In Vitro Fertilization (IVF) in Endometriosis-Related Infertility: When and Why.

Endometriosis is a chronic, estrogen-dependent inflammatory disease characterized by the presence of endometrial tissue outside the uterus, causing pelvic pain and infertility. Infertility arises mainly due to inflammatory mediators in the peritoneal fluid, contributing to local hypoestrogenism, which appears to exacerbate chronic inflammation and sensitize pelvic nerves. Local hypoestrogenism within endometriotic lesions contrasts with the systemic estrogen-dependent nature of the disease.

SIGMAP: an explainable artificial intelligence tool for SIGMA-1 receptor affinity prediction.

Developing sigma-1 receptor (S1R) modulators is considered a valuable therapeutic strategy to counteract neurodegeneration, cancer progression, and viral infections, including COVID-19. In this context, tools capable of accurately predicting S1R affinity are highly desirable. Herein, we present a panel of 25 classifiers trained on a curated dataset of high-quality bioactivity data of small molecules, experimentally tested as potential S1R modulators.

Spectral CT for non-invasive evaluation of bladder cancer grade.

Objective: To investigate the potential role of dual-energy spectral computer tomography (CT) quantitative parameters in the definition of bladder cancer (BCa) pathological grading.

Methods: This retrospective study evaluated the use of spectral CT imaging features for BCa. From 2021 to 2023, 63 patients with histologically-confirmed BCa diagnosis were examined at our Institution.

First-In-Class Thiosemicarbazone Metal Complexes Targeting the Sigma-2 Receptor (S2R) as an Innovative Strategy against Pancreatic Cancer.

Pancreatic cancer, with its increasing incidence and lowest 5-year survival rate, is predicted to become the second leading cause of cancer deaths by 2030. Current clinical trials have shown limited improvement, highlighting the need for new therapies. The sigma-2 receptor (S2R), with roles in tumor progression, is a target for novel thiosemicarbazones (TSCs).
