Chronic Diarrhea Caused by Amebic Colitis and Inflammatory Bowel Disease

The diagnosis of intestinal amebiasis is easily established based on colonoscopy, i.e. there is a specific characteristic of ulcer/lesion “discrete flask-shape ulcer” with normal mucosa among the ulcers. However, most patients with amebic colitis have non-specific clinical manifestations and their colonoscopy findings are hardly distinguished from inflammatory bowel disease. In the present case, the patient had a chief complaint of chronic bleeding diarrhea and abdominal pain. The fecal analysis found trophozoites of Entamoeba histolytica. Serology test (sero-amebic) revealed negative result. The colonoscopy examination reveals hyperemic mucosa, edema, and multiple ulcers with various sizes covered with fragile and easily bleed debris, from the rectum to ascending colon, rigid colon, narrowing lumen and tumor/mass appearance on ascending colon. The differential diagnosis was severe amebic colitis and inflammatory bowel disease. Based on the colonoscopy biopsy, we found an active chronic colitis along with dysplasia. The patient received management and treatment of severe amebic colitis and inflammatory bowel disease

The Physics of the Colloidal Glass Transition

As one increases the concentration of a colloidal suspension, the system exhibits a dramatic increase in viscosity. Structurally, the system resembles a liquid, yet motions within the suspension are slow enough that it can be considered essentially frozen. This kinetic arrest is the colloidal glass transition. For several decades, colloids have served as a valuable model system for understanding the glass transition in molecular systems. The spatial and temporal scales involved allow these systems to be studied by a wide variety of experimental techniques. The focus of this review is the current state of understanding of the colloidal glass transition. A brief introduction is given to important experimental techniques used to study the glass transition in colloids. We describe features of colloidal systems near and in glassy states, including tremendous increases in viscosity and relaxation times, dynamical heterogeneity, and ageing, among others. We also compare and contrast the glass transition in colloids to that in molecular liquids. Other glassy systems are briefly discussed, as well as recently developed synthesis techniques that will keep these systems rich with interesting physics for years to come.Comment: 56 pages, 18 figures, Revie

Antioxidant Capacity and Phytochemical Profile of Punica granatum L.Peel Ex-tracts Using Different Solvent Extraction

Pomegranate is known to have valuable nutrients and contains various bioactive compounds found in the fruit's peel. The utilization of these bioactive compounds could be used as herbal medicines and supplements, such as antioxidants. This study aimed to determine the antioxidant capacity, phytochemical profile, and pomegranate peel extract grouping using different extracting solvents. The extraction solvents used were water, 70% ethanol, and ethanol pro analysis (p.a) grade. The antioxidant capacity of the three extracts was measured using DPPH and CUPRAC methods. We also determined the total phenolic and flavonoid levels and the TLC fingerprint analysis and FTIR spectrum of the pomegranate peel extracts. The 70% ethanol extract owned the largest antioxidantcapacity. Itwas significantly different fromthe other two extracts with a value of 358.67 and 2981.59 μmol trolox/g dried sample using the DPPH and CUPRAC methods, respectively. The three pomegranate peel extracts' total phenolic and flavonoid levels ranged from 287.26–1068.81 mg GAE/g dried sample and 0.24-0.75 mg QE/g dried sample. TLC fingerprint analysis of pomegranate peel extract yielded 2, 6, and 6 bands for water extract, 70% ethanol, and p.a ethanol, respectively. The three extracts can be grouped based on FTIR spectrum data using principal component analysis using three principal components with a total variance of 93%. The results obtained showed that using different extracting solvents provides different antioxidant capacities and phytochemical profiles
