Analyzing Oxidative Stress in Murine Intestinal Organoids using Reactive Oxygen Species-Sensitive Fluorogenic Probe

[Parameters of oxidative stress in patients with gastric cancer]
Abstract:
We studied effect of the neoplastic process and surgical treatment on parameters of the oxidative system in patients with stomach cancer including serum and gastric tissue levels of malonic dialdehyde, lactic and pyruvic acids in stage I-IV malignancy before and after radical surgery. The development and generalization of the neoplastic process are associated with the activation of oxidative reactions leading to endotoxicosis. Specific anticarcinogenic treatments (including surgery) aggravate changes in the oxidative systems and further deteriorate quality of life and tolerance of the treatment.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
Peptic ulcers can also be...
Peptic Ulcer Disease IV: Management
The therapeutic approach involves ensuring adequate rest, implementing drug therapy, promoting smoking cessation, making dietary modifications, and emphasizing long-term follow-up care.
Pharmacological management
The prevailing therapy for peptic ulcers involves a combination of managing the patient's current medication...
