Exploring mechanisms of britannin against colorectal cancer based on experimentally validated network pharmacology.

Britannin is an active compound derived from Inula japonica Thunb. that possess a wide range of pharmacological activities. However, the mechanism underlying its influence on colorectal cancer (CRC) is not clear.

Multicenter analysis on the correlation between the anatomical characteristics of hepatic veins and hepatic venous wedge pressure.

Background: Wedged hepatic venous pressure (WHVP) is a crucial variable for accurately assessing the hepatic venous pressure gradient (HVPG) and is vital for the diagnosis and prognostic evaluation of patients with portal hypertension (PH).

Aim: To investigate the anatomical characteristics of balloon-occluded hepatic venous angiography in patients with PH and analyze the relationship between the WHVP and portal venous pressure (PVP).

Methods: This retrospective study included 877 patients with PH who met the inclusion criteria from January 2020 to June 2024.

Long-term effects of antibiotics, norfloxacin, and sulfamethoxazole, in a partial life-cycle study with zebrafish (Danio rerio): effects on growth, development, and reproduction.

A partial life-cycle study with zebrafish (Danio rerio) was conducted to evaluate the long-term effects of antibiotics, norfloxacin (NOR) and sulfamethoxazole (SMX). A series of bio-endpoints correlated to the growth, development, and reproduction was assessed. The results showed that the body weight and the condition factor were depressed by SMX at 200 μg/L during the growth period.

Modulation of 17β-estradiol induced estrogenic responses in male goldfish (Carassius auratus) by benzo[a]pyrene and ketoconazole.

The aquatic environment is challenged with complex mixtures of chemicals that may interact biochemically with each other in non-target aquatic organisms through a combination of actions, resulting in unpredictable mixture toxicity. This study focuses on the interactive effects of chemicals, including benzo(a)pyrene (BaP) and ketoconazole (KCZ), on 17β-estradiol (E2)-induced estrogenic responses in male goldfish (Carassius auratus). The possible interactions between BaP or KCZ and E2 were investigated on the expression of cytochromeP4501A (CYP1A, biotransformation enzyme) and on its corresponding catalytic activity 7-ethoxyresorufin-O-deethylase (EROD activity), as well as on the expression of CYP19 (steroidogenic enzyme) and E2 bioaccumulation in liver.

Interaction of 17β-estradiol and ketoconazole on endocrine function in goldfish (Carassius auratus).

An understanding of the effects of toxic mixtures of endocrine disrupting chemicals (EDCs) on aquatic organisms is challenging as these organisms are exposed to multiple classes of contaminants in their natural habitat. The aim of the present study was to evaluate the interactions of two classes of EDCs, 17β-estradiol (E2) and ketoconazole (KTC), on endocrine function in male goldfish (Carassius auratus), including vitellogenesis, metabolic capability and serum steroid synthesis. Changes in vitellogenin (VTG) concentration, liver 7-ethoxyresorufin-O-deethylase (EROD) activity and circulating serum E2 level were examined.
