A case of gastric hyperplastic polyp with proliferation of xanthoma cells is reported. The patient was a 69-year-old man who visited our hospital for further evaluation of gastric polyps. Endoscopic examination of the upper digestive tract revealed multiple hyperplastic polyps in the gastric antrum. There was a pedunculated polyp with whitish yellow granules, 7 mm in diameter, arising from the ...
The use of narrow bore LC capillaries operated at ultralow flow rates coupled with mass spectrometry provides a desirable convergence of figures of merit to support high-performance LC-MS/MS analysis. This configuration provides a viable means to achieve in-depth protein sequence coverage while maintaining a high rate of data production. Here we explore potential performance improvements afford...
due to high resolution power of sulfated cyclodextrins (hs-cds), utilization of these selectors for chiral resolution of 7 basic and 2 zwitterionic drugs have been examined. experiments were performed on a hp3dce instrument equipped with an on-column diode array uv absorbance detector. fused silica capillaries with an inner diameter of 50 ?m, an outer diameter of 365 ?m, and a total length of 4...
Erythrocytes are flexible cells specialized in the systemic transport of oxygen in vertebrates. This physiological function is connected to their outstanding ability to deform in passing through narrow capillaries. In recent years, there has been an influx of experimental evidence of enhanced cell-shape fluctuations related to metabolically driven activity of the erythroid membrane skeleton. Ho...
Introduction: Diabetes mellitus is a metabolic disorder with systemic complications. Children of diabetic mothers are at risk of many disorders such as major and minor vascular injuries, retinopathy, and atherosclerosis. The present study aimed to investigate the effects of maternal diabetes on changes in choroid plexus volume and capillaries length in 15.5 day foetus. Methods: in this experi...
AIMS To assess quantitatively variations in the extent of capillary basement membrane (BM) thickening between different retinal layers and within arterial and venous environments during diabetes. METHODS One year after induction of experimental (streptozotocin) diabetes in rats, six diabetic animals together with six age-matched control animals were sacrificed and the retinas fixed for transm...
Red blood cells squeeze through micro-capillaries as part of blood circulation in the body. The deformability of red blood cells is thus critical for blood circulation. In this work, we report a method to optically squeeze red blood cells using the evanescent field present on top of a planar waveguide chip. The optical forces from a narrow waveguide are used to squeeze red blood cells to a size...
