AB  - Infertility is a major global health issue, affecting approximately 9% of couples worldwide. Its prevalence increased steadily over the preceding decades, paralleling environmental and lifestyle changes. One assisted reproductive technique to overcome infertility is in vitro fertilization (IVF). The IVF procedure consists of several stages, one of which is controlled ovarian stimulation (COS) via various protocols allowing follicular recruitment and maturation in preparation for oocyte retrieval. Follicular fluid (FF) is the microenvironment in which oocytes develop during folliculogenesis, and FF information could be used to assess follicle and oocyte development and maturation stages. Nitric oxide (NO) is a component of FF that is being studied as a predictive factor of follicle maturation and egg quality and as a potential indicator of the success of COS during the IVF process. The hypothesis was that COS affects NO levels in the serum; more specifically, that NO levels in serum after COS correlate with NO levels in FF, based on literature data on the influence of female reproductive hormones on NO metabolism and data on the change in the hormonal milieu affected by COS use. Furthermore, it was hypothesized that NO levels in serum and FF after COS were related to the number of high-quality female reproductive cells obtained during IVF. Assuming that NO levels in serum after COS correlate with NO levels in FF, the central hypothesis of this study is that serum NO levels after COS could be a valuable predictor of oocyte quality and the number of high-quality female reproductive cells achieved by COS. As a result of the hypothesis, measuring NO could be a novel way to improve the efficiency of IVF treatment.

AB  - Thioacetamide (TAA) is widely used to study liver toxicity accompanied by oxidative stress, inflammation, cell necrosis, fibrosis, cholestasis, and hepatocellular carcinoma. As an efficient free radical’s scavenger, C60 fullerene is considered a potential liver-protective agent in chemically-induced liver injury. In the present work, we examined the hepatoprotective effects of two C60 doses dissolved in virgin olive oil against TAA-induced hepatotoxicity in rats. We showed that TAA-induced increase in liver oxidative stress, judged by the changes in the activities of SOD, CAT, GPx, GR, GST, the content of GSH and 4-HNE, and expression of HO-1, MnSOD, and CuZnSOD, was more effectively ameliorated with a lower C60 dose. Improvement in liver antioxidative status caused by C60 was accompanied by a decrease in liver HMGB1 expression and an increase in nuclear Nrf2/NF-κB p65 ratio, suggesting a reduction in inflammation, necrosis and fibrosis. These results were in accordance with liver histology analysis, liver comet assay, and changes in serum levels of ALT, AST, and AP. The changes observed in gut microbiome support detrimental effects of TAA and hepatoprotective effects of low C60 dose. Less protective effects of a higher C60 dose could be a consequence of its enhanced aggregation and related pro-oxidant role.

AB  - The effects of twelve weeks of supplementation with fullerene C60 olive/coconut oil solution on a broad spectrum of parameters in rats were examined. The tissue bioaccumulation of C60 was shown to be tissue-specific, with the liver, heart, and adrenal glands being the organs of the greatest, and the kidney, brain, and spleen being the organs of the smallest accumulation. C60 did not change aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase serum activities level, nor the damage of liver cells DNA. There were no effects of fullerene on prooxidant-antioxidant balance in the liver, kidney, spleen, heart, and brain, nor any visible harmful effects on the liver, heart, aorta, spleen, kidney, and small intestine histology. Fullerene changed the gut microbiota structure towards the bacteria that ameliorate lipid homeostasis, causing a serum triglycerides concentration decrease. However, C60 significantly increased the insulin resistance, serum ascorbate oxidation, and brain malondialdehyde and advanced oxidation protein products level. The deteriorative effects of C60 on the brain and serum could be attributed to the specific physicochemical composition of these tissues, potentiating the C60 aggregation or biotransformation as the key element of its pro-oxidative action.

AB  - Background: Cyclin A overexpression is found in a variety of human tumors and correlates with unfavorable outcome. We analyzed immunohistochemical expression of cyclin A in Wilms tumor (WT) in relation to clinicopathological characteristics, preoperative chemotherapy (PrOpChTh), and overall survival (OS). Methods: This retrospective study involved 43 patients who underwent nephrectomy from January 1996 to October 2010. Tumor stage and histological subtype were determined by revised Societé International d’Oncologie Pediatrique protocol, based on histological components/alterations caused by PrOpChTh, within the prognostic group of low, intermediate and high risk, and with criteria for anaplasia. The regressive/necrotic changes in total tumor mass of primary tumor and the proportion of epithelial, blastemal, and stromal components in the remaining viable tumor tissue were also determined. Cyclin A expression was evaluated by immunohistochemistry using a polyclonal rabbit, antihuman antibody (H-432). Results: Cyclin A overexpression was found in 34.3% of WTs, with higher frequency in tumors with epithelial (31.3%) and blastemal (37.1%) components than those with stromal component (17.7%). Regarding histological type, cyclin A overexpression was found most often in focal anaplasia (100%), stromal (60%), and diffuse anaplastic (66.7) WTs. The overexpression was also more frequent in stages 3 and 4 (77.8% and 66.7%, respectively) compared to tumors in stages 1 and 2 (13.3% and 12.5%, respectively; p = 0.004) in all components, as well as in blastemal component in stages 3 and 4 (77.8% and 66.7%, respectively) vs. stages 1 and 2 (13.3% and 25%, respectively, p = 0.009). Cyclin A overexpression in all components was 66.7% in WTs with metastasis and 31.3% in WTs without metastasis (p = 0.265, Fisher test). Log-rank testing revealed differences of OS regarding stage (p = 0.000), prognostic groups (p = 0.001), and cyclin A expression in blastemal component (p = 0.025). After univariate analysis, tumor stage (p = 0.001), prognostic group (p = 0.004), and cyclin A expression in blastemal component (p = 0.042) were significant prognostic factors for OS; however, after multivariate analysis, none of these factors were confirmed as independent predictors of survival. Discussion: This study showed that cyclin A overexpression might be associated with the development and progression of WT with anaplasia. Also, cyclin A overexpression was more often observed in advanced stages (3 and 4) of WT, in the group of high-risk WTs, and in focal and diffuse anaplasia WTs. There was no relation of cyclin A overexpression and metastatic ability of WT. Although this study has not confirmed the prognostic value of cyclin A overexpression, its association with unfavorable prognosis should be further evaluated. Copyright 2019 Radojevic-Škodric et al.

AB  - Purpose: There is a need for identifying molecular prognostic biomarkers to better predict clinical outcomes in patients with renal cell carcinoma (RCC). This study investigated the pattern of cyclin D1 and p57 expression in RCC patients and evaluated their relation with clinicopathological characteristics and overall survival (OS). Methods: Immunohistochemistry was applied to paraffin-embedded tissue sections of 74 RCC patients. Two cut-off groups were defined by the fraction of positive cells as fol-lows: ≤10% and >10% positive cells for cyclin D1, and ≤5% and >5% positive cells for p57. Results: Cyclin D1 expression in >10% of positive cells was observed mostly in the clear cell RCC, while p57 expression in ≤5% of positive cells was found in 86% of chromophobe RCC specimens. The higher expression of cyclin D1 and lower expression of p57 were more frequent in grade I-II tumors. OS was associated with unfavorable clinicopathological characteristics. However, cyclin D1/p57 expression did not influence the survival rates. Conclusion: Although cyclin D1 and p57 expression did not affect survival rates in RCC patients, proper validation and establishment of the qualitative cut-off point are needed for these tumors.
