Association between cholesterol-phospholipid vesicles and cholesterol crystals in human gallbladder bile [PDF]

open access: yes, 1989
Rapid aggregation of cholesterol-phospholipid vesicles in gallbladder bile seems to be the first event in the production of cholesterol crystals, a prerequisite for cholesterol gallstone formation.

Cooperative Assistance in Robotic Surgery through Multi-Agent Reinforcement Learning [PDF]

open access: yes, 2021
Cognitive cooperative assistance in robot-assisted surgery holds the potential to increase quality of care in minimally invasive interventions. Automation of surgical tasks promises to reduce the mental exertion and fatigue of surgeons. In this work, multi-agent reinforcement learning is demonstrated to be robust to the distribution shift introduced by

Fibronectin in human gallbladder bile: cholesterol pronucleating and/or mucin "link" protein? [PDF]

open access: yes, 1994
Some biliary proteins (pronucleators) seem to be essential factors for cholesterol crystal formation and crystal growth in bile. A recent study suggests that fibronectin is such a pronucleator in bile.

Pancreas divisum. Correlation between anatomical abnormalities and bile precipitation in the gallbladder in seven patients [PDF]

open access: yes, 2016
Pancreas divisum is a genetic defect associated with recurrent acute pancreatitis due to insufficient drainage of the accessory pancreatic duct. Seven young patients diagnosed with pancreatic divisum and thickening of the gallbladder bile as shown on ...

Gallbladder Volvulus [PDF]

open access: yesHPB Surgery, 1992
A case of torsion of the gallbladder is presented. This is a rare condition that occurs more frequently in elderly females, it is associated with anatomical variants related to abnormal fixation of the gallbladder to the liver bed. It is usually diagnosed at laparotomy and treatment consists of cholecystectomy.

RadFormer: Transformers with Global-Local Attention for Interpretable and Accurate Gallbladder Cancer Detection [PDF]

open access: yesarXiv, 2022
We propose a novel deep neural network architecture to learn interpretable representation for medical image analysis. Our architecture generates a global attention for region of interest, and then learns bag of words style deep feature embeddings with local attention.

Regulation of Human Adipose Tissue Activation, Gallbladder Size, and Bile Acid Metabolism by a β3-Adrenergic Receptor Agonist

open access: yesDiabetes, 2018
β3-adrenergic receptor (AR) agonists are approved to treat only overactive bladder. However, rodent studies suggest that these drugs could have other beneficial effects on human metabolism. We performed tissue receptor profiling and showed that the human

Indomethacin decreases viscosity of gallbladder bile in patients with cholesterol gallstone disease [PDF]

open access: yes, 1993
There is experimental evidence that inhibition of cyclooxygenase with nonsteroidal anti-inflammatory drugs may decrease cholesterol gall-stone formation and mitigate biliary pain in gall-stone patients.

Management and follow-up of gallbladder polyps

open access: yesEuropean Radiology, 2017
ObjectivesThe management of incidentally detected gallbladder polyps on radiological examinations is contentious. The incidental radiological finding of a gallbladder polyp can therefore be problematic for the radiologist and the clinician who referred ...

A Multiple-Instance Learning Approach for the Assessment of Gallbladder Vascularity from Laparoscopic Images [PDF]

open access: yesarXiv, 2021
An important task at the onset of a laparoscopic cholecystectomy (LC) operation is the inspection of gallbladder (GB) to evaluate the thickness of its wall, presence of inflammation and extent of fat. Difficulty in visualization of the GB wall vessels may be due to the previous factors, potentially as a result of chronic inflammation or other diseases.
