An Interactive Automation for Human Biliary Tree Diagnosis Using Computer Vision [PDF]

arXiv, 2022
The biliary tree is a network of tubes that connects the liver to the gallbladder, an organ right beneath it. The bile duct is the major tube in the biliary tree. The dilatation of a bile duct is a key indicator for more major problems in the human body, such as stones and tumors, which are frequently caused by the pancreas or the papilla of vater. The

Cell‐free and extracellular vesicle microRNAs with clinical utility for solid tumors

Molecular Oncology, EarlyView.
Cell‐free microRNAs (cfmiRs) are small‐RNA circulating molecules detectable in almost all body biofluids. Innovative technologies have improved the application of cfmiRs to oncology, with a focus on clinical needs for different solid tumors, but with emphasis on diagnosis, prognosis, cancer recurrence, as well as treatment monitoring.

Adenosine A3 receptor antagonists as anti‐tumor treatment in human prostate cancer: an in vitro study

FEBS Open Bio, EarlyView.
The A3 adenosine receptors (A3ARs) are overexpressed in prostate cancer. AR 292 and AR 357, as A3AR antagonists, are capable of blocking proliferation, modulating the expression of drug transporter genes involved in chemoresistance, ferroptosis, and the hypoxia response, and inducing cell death.

Effect of phospholipids and bile acids on cholesterol nucleation time and vesicular/micellar cholesterol in gallbladder bile of patients with cholesterol stones [PDF]

, 1993
Supersaturation and rapid nucleation of cholesterol in bile are of key importance in the pathogenesis of cholesterol gallstones. While the effects of bile acids and phospholipids on cholesterol saturation of bile have been extensively studied, their ...

The Regulation of Trace Metal Elements in Cancer Ferroptosis

Advanced Biology, EarlyView.
The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.

Cholic Acid-Based Mixed Micelles as siRNA Delivery Agents for Gene Therapy [PDF]

International Journal of Pharmaceutics, 2020, 578, pp.119078
Gene therapy is a promising tool for the treatment of various cancers but is hindered by the physico-chemical properties of siRNA and needs a suitable vector for the delivery of siRNA to the target tissue. Bile acid-based block copolymers offers certain advantages for the loading and delivery of siRNA since they can efficiently complex siRNA and bile ...

Very long O-antigen chains enhance fitness during Salmonella-induced colitis by increasing bile resistance. [PDF]

, 2012
Intestinal inflammation changes the luminal habitat for microbes through mechanisms that have not been fully resolved. We noticed that the FepE regulator of very long O-antigen chain assembly in the enteric pathogen Salmonella enterica serotype ...

Lipid components of bile increase the protective effect of conjugated bile salts against antifungal drugs [PDF]

, 2017
Fungi and bacteria can persist in the human gall bladder. Previous studies have shown that bile protects Candida albicans in this cryptic host niche from antifungals, providing a reservoir for intestinal re-colonization after discontinuation of ...
