Ultrastructural evaluation of the effect of endosulfan on mice kidney
In this study, the effect of the endosulfan on
mice kidney was investigated at ultrastructural level.
Moreover, biochemical analyses (G6PD, CAT, SOD,
GSH and MDA) were determined in supernatant of
kidney tissue. Endosulfan (13mg/kg/day body weight)
was administered orally to mices via intragastric-during
10 days. The presence of mitochondrial degeneration in
cytoplasm of proximal convoluted tubule cells were a
striking feature. Furthermore, there was lipofuscin
granules and membranous structures in some of
proximal convoluted tubule cells. In some glomeruli,
ultrastructural changes such as fusion in pedicels and
focal thickening at glomerular basal membrane were
seen. There were cytoplasmic bulges in some distal
convoluted tubule cells. The biochemical results of the
experimental group were significant when compared to
the control. The effect of the endosulfan was mainly on
the proximal convoluted tubule cells. Morever, the other
parts of the nephron were effected. Thus, this
degeneration in kidney may be thought that oxidative
stress may play a role to the mediator in changing
configuration of cell membrane and seem to account for
the morphologic alteration of kidney
Reliability of Colposcopy in Turkey: Correlation with Pap Smear and 1-year Follow Up
Ankarali, Handan Camdeviren/0000-0002-3613-0523WOS: 000343833100055PubMed: 25227835Background: A cytologic reading of a Papanicolaou ( pap) smear followed, if the result is positive, by a colposcopic search for abnormal cells is the most common screening method for cervical cancer used worldwide. We aimed to present the correlation of smear and colposcopic findings with 6- to 12-month follow-up results and related factors in women who underwent colposcopy in Turkey. Materials and Methods: The study population consisted of women who attended the gynecology department and were referred for colposcopic evaluation in 2011-2012. A total of 232 women between ages 17 and 68 years were included. Colposcopy indications were ASCUS and higher lesions at cervical smear, macroscopic suspicious lesions, post-coital bleeding history with suspicious smear, and repeated cervical inflammation. All patients were recalled for 6- to 12-month follow-ups. Results: The most common colposcopy indication was ASCUS, and the most common biopsy result was inflammation. Nearly half of the patients returned for the control 6-month follow-up, and almost 20% of patients for a 1-year follow up. Conclusions: Colposcopic biopsy is an effective method in indicated patients but is not sufficient in itself if awareness of the subject is not raised in the population. One of the most important aims of cancer screening programs should be enabling patients in developing countries to take responsibility. Patients must be encouraged to apply to the hospital for better disease control
Protective effects of Acetobacter ghanensis against gliadin toxicity in intestinal epithelial cells with immunoregulatory and gluten-digestive properties
Purpose The aim of this study was to establish whether Acetobacter ghanensis, the probiotic characteristics of which were evaluated previously, attenuates gliadin-induced toxicity in intestinal epithelial cells with gluten-digestive and immunoregulatory properties. Methods A co-culture model of human intestinal epithelial cell (Caco-2) monolayers on top of peripheral blood mononuclear cells (PBMCs) obtained from patients with celiac disease (CD) was established. The gluten-digestive properties of A. ghanensis were determined by checking bacterial growth in a medium containing gluten as the main nitrogen source. The mRNA levels of genes encoding TJ-associated proteins were measured by quantitative real-time PCR (qRT-PCR). The concentrations of IL-6 and TNFac were determined by enzyme-linked immunosorbent assay (ELISA). Results We found that PT-gliadin disrupted intestinal barrier integrity by modulating the expression of TJ-associated genes encoding zonulin (increased by similar to 60%), zonula occludens-1 (ZO-1) (decreased by similar to 22%), and occludin (decreased by similar to 28%) in Caco-2 cells. Furthermore, PT-gliadin treatment in Caco-2 cells was associated with increased concentrations of IL-6 (similar to 1.6-fold) and TNFac (similar to twofold) from PBMCs. These modulatory effects of PT-gliadin, however, were suppressed when Caco-2 cells were subjected to A. ghanensis in the presence of PT-gliadin. As a factor underlying these protective effects, we showed that A. ghanensis could digest gluten peptides. Conclusions To our knowledge, the current study is the first to demonstrate that A. ghanensis improves intestinal barrier functions by attenuating the modulatory effects of PT-gliadin with immunoregulatory and gluten-digestive properties.Turkiye Bilimsel ve Teknolojik Arastirma Kurumu [218S759]This study is funded by Turkiye Bilimsel ve Teknolojik Arastirma Kurumu, 218S759, Caglar Dogue
