Effect of kefir on increased apoptosis in liver and kidney in cisplatin toxicity

Int. j. morphol; 40 (2), 2022
SUMMARY: Cisplatin is a chemotherapeutic agent inducing liver and kidney damage. In this study, we intended to investigate the impact of kefir beverage, an essential probiotic and functional food, on liver and kidney damage induced by cisplatin. Wistar albino rats were divided into four groups: Control, ...

Amplification of urea detection based on pH-sensitive liposomes

BACKGROUND: This study aimed to develop an amplification method of urea detection based on pHsensitive liposomes. RESULTS: The urease covalently immobilized on the magnetic particles and the pH-sensitive liposomes encapsulating ferricyanide were added to the cyclic-voltammeter cell solution where urea wa...

Urea incorporated into ordered mesoporous silica for potential cosmetic application

Urea's thermal instability and burning on sensitive skin can cause problems for cosmetic formulations. To overcome these drawbacks, urea was incorporated into ordered mesoporous silica (SBA-15). SBA-15 was synthesized using tetraethyl orthosilicate and Pluronic® P123 in an acid medium. Urea (20 wt.%) wa...

Estudo prospectivo para validação de protocolo único para o teste respiratório com ureia marcada com carbono-13 empregando dois dispositivos diferentes, no diagnóstico da infecção por H. pylori

Arq. gastroenterol; 56 (2), 2019
ABSTRACT BACKGROUND: 13C-urea breath test (UBT) is the gold-standard, noninvasive method for H. pylori diagnosis. However, there is no uniform standardization of the test. This situation can be unpractical for laboratories running with two or more devices. OBJECTIVE: To perform a prospective compariso...

Collapsing glomerulopathy with rapid progression to terminal renal failure

Med. interna (Caracas); 35 (4), 2019
La glomerulopatía colapsante (GC) constituye una variedad de la glomeruloesclerosis focal y segmentaria. Afecta tanto a la población adulta (40%) como a la infantil (20%); presentándose con mayor frecuencia en hombres jóvenes y afrodescendientes. Clínicamente se presenta como un síndrome nefrótico...

Performance of the 13C-urea breath test for the diagnosis of H. pylori infection using a substrate synthesized in Brazil: A preliminary study

Clinics; 73 (), 2018
OBJECTIVE: The 13C-urea breath test is the main non-invasive test for the diagnosis of Helicobacter pylori infection. The availability of this test throughout the country is limited, mainly due to the difficulty in obtaining the labeled isotope from abroad. Recently, researchers from the Nuclear Energy C...

Diagnostic accuracy of urea breath test for helicobacter pylori infection in children with dyspepsia in comparison to histopathology

Arq. gastroenterol; 53 (2), 2016
ABSTRACT Background - Helicobacter pylori infection is the gram negative bacillus with the close association with chronic antral gastritis. Objective - In this study, we evaluate the accuracy of urea breath test (UBT) with carbon isotope 13 in comparison with histopathology of gastric antrum for dete...

Moringa oleifera impairs the morphology and functions of the kidney in adult Wistar rats

Int. j. morphol; 32 (2), 2014
We tested the hypothesis that Moringa oleifera impairs the morphology and functions of the kidney in rats. Twenty-four adult male Wistar rats were employed in the study. Rats of Control Group I received physiological saline while rats of Groups II ­ IV received 250, 500 and 750 mg/kg bodyweight of metha...
