The cardiac differentiation of the African clawed Toad was studied in culture with Actinomycin D. In terms of drug amounts used and the duration of treatment, a limit coefficient was defined, beyond which the heart did not again differentiate. The results were interpreted by the existence of a threshold in the inhibition of ARNr synthesis, whose total turn-over seemed to be 24 hours.

Background: While TRPA1 serves as a therapeutic target for nociceptive pain, its role in acute visceral pain induced by uterine cervical dilation (UCD) remains an enigma. This study aims to elucidate the upstream and downstream mechanisms of TRPA1 in the context of UCD-induced acute visceral pain.
Methods: The UCD rats were administered with SAH (inhibitor of the METTL3-METTL14 complex) via intrathecal tubing.

Coccidiosis, a parasitic disease caused by Eimeria protozoa that parasitizes intestinal tissues of chicken, poses a challenge to the development of the poultry industry. circRNAs are a class of circular RNA macromolecules crucial in the immune response to pathogens. Previous studies have shown that gga-miR-2954 inhibits the inflammatory response to Eimeria tenella (E.

Background: Head and neck squamous cell carcinoma (HNSCC), a highly invasive malignancy with a poor prognosis, is one of the most common cancers globally. Circular RNAs (circRNAs) have become key regulators of human malignancies, but further studies are necessary to fully understand their functions and possible causes in HNSCC.
Methods: CircCCT2 expression levels in HNSCC tissues and cells were measured via qPCR.

Objective: To evaluate the efficacy of actinomycin D (ActD) as prophylactic chemotherapy (P-chem) in patients with high-risk complete hydatidiform mole (Hr-CHM) on progression to gestational trophoblastic neoplasia (GTN).
Methods: From 1996 to 2023, 426 Hr-CHMs were selected in a cohort of 1623 patients with gestational trophoblastic disease (GTD). From 1996 to 2023, 290 patients with Hr-CHMs received a single bolus dose of Act-D at the time of uterine evacuation (Hr-CHM P-chem group); 136 with the same risk factors did not receive P-chem (Hr-CHM control group).

Gestational trophoblastic neoplasia (GTN) comprises a category of malignant or potentially malignant tumors that arise from gestational trophoblasts. Almost all cases of GTN experience a recurrence within the first year following treatment, although recurrences become rare after five years. Recurrent GTN tends to have a poor prognosis, primarily due to challenges in management, a high rate of relapse, and a low five-year survival rate.
