Different Degrees of Sulfated Laminaria Polysaccharides Recovered Damaged HK-2 Cells and Inhibited Adhesion of Nano-COM and Nano-COD Crystals.

Purpose: The crystal adhesion caused by the damage of renal tubular epithelial cells (HK-2) is the key to the formation of kidney stones. However, no effective preventive drug has been found. This study aims to explore the recovery effects of four Laminaria polysaccharides (SLPs) with different sulfate (-OSO) contents on damaged HK-2 cells and the difference in the adhesion of damaged cells to nanometer calcium oxalate monohydrate (COM) and calcium oxalate dihydrate (COD) before and after recovery.

Endoscopic features help to identify the histopathological patterns of colorectal polyps in Cronkhite-Canada syndrome.

Objectives: Cronkhite-Canada syndrome (CCS) is a rare nonhereditary gastrointestinal hamartomatous polyposis syndrome with a high risk of colorectal cancerogenesis. It is challenging to discriminate adenomas from nonneoplastic colorectal polyps macroscopically. This study aimed to explore the endoscopic features of different histopathological patterns of colorectal polyps in CCS.

Ultrasonographic findings in cows with left displacement of abomasum, before and after reposition surgery.

Background: The natural incidence of left displacement of abomasum (LDA) in dairy cows was high. The diagnosis of LDA usually relies on characteristic physical exam findings but that transabdominal ultrasound is a useful technique that has been applied to the diagnosis of gastrointestinal diseases of dairy cows in equivocal cases.

Methods: Forty dairy cows with LDA were clinically and ultrasonographically examined to determine the position and the echogenic property of the abomasum.
