Abstract
Background and Objectives: Inflammation and dysregulation in the intestinal barrier function in acute pancreatitis (AP) trigger pancreatic lesions, systemic inflammatory response, and multiple organ dysfunction. Eugenol, as the main component of clove (Syzygium aromaticum), is known for its antioxidant and anti-inflammatory properties. We studied the potentially beneficial effect of eugenol in a rodent model of biliopancreatic duct ligation-induced AP. Materials and Methods: Rats were randomly divided into three groups: Sham, AP, and AP + eugenol (15 mg/kg/day). Serum TNFα, IL-6, IL-18, and resistin levels, as well as IL-6, TNFα, MPO, HMGB1, and CD45 tissue expression, were determined at various timepoints after the induction of AP. Results: Eugenol attenuated hyperemia and inflammatory cell infiltration in the intestinal mucosal, submucosal, and muscular layers. IL-6 and resistin serum levels were significantly reduced in the AP + eugenol group, while serum TNFα and IL-18 levels remained unaffected overall. TNFα pancreatic and intestinal expression was attenuated by eugenol at 72 h, while IL-6 expression was affected only in the pancreas. MPO, CD45, and HMGB1 intestinal expression was significantly reduced in eugenol-treated rats. Conclusions: Eugenol managed to attenuate the inflammatory response in the intestine in duct ligation-induced AP in rats.

Abstract
Raman spectroscopy has emerged as a powerful tool in medical, biochemical, and biological research with high specificity, sensitivity, and spatial and temporal resolution. Recent advanced Raman systems, such as portable Raman systems and fiber-optic probes, provide the potential for accurate in vivo discrimination between healthy and cancerous tissues. In our study, a portable Raman probe spectrometer was tested in immunosuppressed mice for the in vivo localization of colorectal cancer malignancies from normal tissue margins. The acquired Raman spectra were preprocessed, and principal component analysis (PCA) was performed to facilitate discrimination between malignant and normal tissues and to highlight their biochemical differences using loading plots. A transfer learning model based on a one-dimensional convolutional neural network (1D-CNN) was employed for the Raman spectra data to assess the classification accuracy of Raman spectra in live animals. The 1D-CNN model yielded an 89.9% accuracy and 91.4% precision in tissue classification. Our results contribute to the field of Raman spectroscopy in cancer diagnosis, highlighting its promising role within clinical applications.

Abstract
HELLP (Hemolysis, Elevated Liver enzymes and Low Platelets) syndrome is a life-threatening complication of pregnancy, which is often secondary to preeclampsia. To date, there is no biomarker in clinical use for the early stratification of women with preeclampsia who are under increased risk of HELLP syndrome. Herein, we show that the levels of circulating developmental endothelial locus-1 (DEL-1), which is an extracellular immunomodulatory protein, are decreased in patients with HELLP syndrome compared to preeclampsia. DEL-1 levels are also negatively correlated with the circulating levels of kidney injury molecule-1 (KIM-1), which is a biomarker for disorders associated with kidney damage. Receiver-operating characteristic curve analysis for DEL-1 levels and the DEL-1 to KIM-1 ratio demonstrates that these values could be used as a potential biomarker that distinguishes patients with HELLP syndrome and preeclampsia. Finally, we show that placental endothelial cells are a source for DEL-1, and that the expression of this protein in placenta from patients with HELLP syndrome is minimal. Taken together, this study shows that DEL-1 is downregulated in HELLP syndrome both in the circulation and at the affected placental tissue, suggesting a potential role for this protein as a biomarker, which must be further evaluated.

Abstract
INTRODUCTION The relationship between disease severity and exposure to allergens in allergic rhinitis (AR) patients is not fully clarified presently. We aimed to detect the correlation between airborne pollen and fungi concentrations in a Mediterranean region with symptom scores. METHODS A total of 98 patients suffering from AR rated their symptoms at the time of exacerbation using the Total 5 Symptoms Score (T5SS) and the Visual Analogue Scale (VAS). Patients' quality of life (QoL) was estimated by using either disease-specific (Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) and mini-RQLQ) or generic (Short-Form 36 (SF-36) and Beck Depression Inventory (BDI)) questionnaires. All patients' responses were correlated with aerobiological data. Skin prick tests (SPTs) were used to detect sensitivities to the most common registered pollen and fungi species. RESULTS A significant positive correlation between total pollen and fungi counts and disease-specific questionnaires was found only for the RQLQ. Accordingly, a significant positive correlation was found between total pollen and fungi counts and T5SS (r = 0.655, p = 0.021), with breathing (r = 0.620, p = 0.032) and sneezing (r = 0.660, p = 0.020) being strongly affected. Moreover, a tendency toward a higher VAS score was found as total pollen and fungi counts increased (r = 0.523, p = 0.081). CONCLUSION We found a significant correlation between patients' symptoms and pollen and fungal air concentrations. Our results emphasize the clinical significance of pollen and fungi maps in everyday clinical practice.

Abstract
INTRODUCTION Sarcomatoid urothelial carcinoma (SUC) is a rare and aggressive variant of bladder cancer with limited data guiding prognosis. In this study, we present the first prognostic nomograms in the literature for 3- and 5-year overall survival (OS) and disease-specific survival (DSS), for patients with SUC derived from the surveillance, epidemiology and end results database (SEER). MATERIALS AND METHODS Patients with SUC were identified by using the ICD-10 topography codes C67.0-C67.9 (bladder cancer), and the morphologic code 8122 (SUC). Patients were randomly divided into a training cohort (TC) and a validation cohort (VC) (7:3 ratio). Variables significantly associated with OS and DSS were identified with multivariate Cox regression and were used to build the nomograms. Harrel's C-statistic with bootstrap resampling and calibration curves were used for internal (TC) and external (VC) validation. Clinical utility of the nomograms was assessed with the decision curve analysis (DCA). Goodness of fit between the nomograms and the AJCC 8th edition staging system was compared with the likelihood ratio test. RESULTS A total of 741 patients with SUC were included (507 TC, 234 VC). No statistically significant differences in baseline characteristics were identified between the 2 cohorts. Sex, SEER stage, radical cystectomy and chemotherapy were common variables for the OS and the DSS nomograms with the addition of age in the former. Optimism-corrected C-statistic for the nomograms was 0.68 and 0.67 for OS and DSS respectively. In comparison, C-statistic for AJCC was 0.59 for OS and 0.60 for DSS (P < 0.001). Calibration curves constructed for the nomograms showed appropriate consistency between predicted and actual survival. The nomograms demonstrated optimal clinical utility in the DCA, outperforming the AJCC staging system, by maintaining a higher clinical net benefits than treat all, treat none and AJCC curves, across threshold probabilities. CONCLUSION We present the first prognostic nomograms developed in patients with SUC. Our models demonstrated superior prognostic performance to the AJCC system, by utilizing a set of variables readily available in daily practice and may serve as useful tools for the individualized risk assessment of these patients.

Abstract
Congenital Herpes simplex virus (HSV) infection is considered a common pregnancy pathology that is not always easy to diagnose. This study aimed to present the spectrum of placental histopathological lesions in pregnancies complicated by HSV infection. MEDLINE and Google Scholar databases were searched using the keywords "HSV" and "placental histopathology" up to June 20, 2022. Study inclusion required presenting placental histopathological anomalies in pregnant women diagnosed with HSV infection antenatally, during labor, or postnatally. Herein, we briefly present placental pathogenesis conditions, which have been correlated with congenital HSV infection, providing clinicians with a short review describing herpetic placental pathology.

Abstract
BACKGROUND Radiofrequency-assisted liver resection (RF-LR) techniques minimize intraoperative blood loss, while avoiding the Pringle maneuver. Both surgical excision and radiofrequency ablation of liver parenchyma compromise gut barrier function with subsequent bacterial translocation. The present study sought to investigate in a porcine model the impact of two RF-LR techniques on the integrity and inflammatory response of the gut barrier. METHODS Twenty-four pigs were subjected to either (a) partial hepatectomy (PH) employing the "sequential coagulate-cut" technique using a monopolar electrode (SCC group), the one using the bipolar Habib-4X device (group H), or the "crush-clamp" technique (group CC) or (b) sham operation (group Sham). At 48-h post-operation, ileal tissue was excised to be subjected to histopathologic examination, histomorphometric analysis, and immunohistochemical assessment of the mitotic and apoptotic activities and the expression of interleukin-6 (IL-6), tumor necrosis factor-α (TNFα), and nuclear factor-κB (NFκΒ). RESULTS Histopathologic score increased in all PH groups, being higher in group SCC, while lower in group H. Villous height decreased in group SCC only. Mitotic index decreased, while apoptotic index increased in all PH groups. An increase in tissue expression score was noted for IL-6 in group CC, for TNFα in all PH groups, being lower in group H compared to group CC, and for NFκB in all PH groups. CONCLUSIONS The Habib-4X technique for liver resection proved to preserve the integrity of gut barrier, being less injurious in the intestinal mucosa compared to the SCC and CC techniques.

Abstract
OBJECTIVE Endometrial cancer is a threat to women health worldwide. Cylindromatosis (CYLD) enzyme is a tumour suppressor, considered an effective prognostic marker in various malignancies, but its role in endometrial carcinoma is not fully elucidated. Here, we sought to estimate the prognostic value of CYLD expression in endometrial carcinoma. MATERIALS AND METHODS CYLD levels were immunohistochemically evaluated in 65 patients with endometrial carcinoma and inferential statistics were applied. RESULTS Low or negative CYLD expression significantly correlates with older ages, non-endometrioid and invasive carcinomas, tumours with moderate or poor differentiation and advanced stages. Moreover, non-endometrioid and invasive carcinomas are independent risk factors for weaker CYLD expression. Kaplan-Meier analysis illustrated that negative or low CYLD expression is statistically significantly associated with increased death risk, compared to moderate or high expression. CONCLUSION This study demonstrates for the first time a clear correlation between CYLD expression and clinicohistopathological parameters of endometrial carcinoma patients, suggesting its use as a potential prognostic/predictive marker for Endometrial Carcinoma.

Abstract
Recurrent implantation failure (RIF) is a multifactorial condition affecting 10-15% of in vitro fertilization (IVF) couples. Data suggest that functional dysregulation of the endometrial immune system constitutes one of the main pathophysiological mechanisms leading to RIF. The aim of this article is to provide a thorough presentation and evaluation of the role of interleukins (ILs) in the pathogenesis of RIF. A comprehensive literature screening was performed summarizing current evidence. During implantation, several classes of ILs are secreted by epithelial and stromal endometrial cells, including IL-6, IL-10, IL-12, IL-15, IL-18, and the leukemia inhibitory factor. These ILs create a perplexing network that orchestrates both proliferation and maturation of uterine natural killer cells, controls the function of regulatory T and B cells inhibiting the secretion of antifetal antibodies, and supports trophoblast invasion and decidua formation. The existing data indicate associations between ILs and RIF. The extensive analysis performed herein concludes that the dysregulation of the ILs network indeed jeopardizes implantation leading to RIF. This review further proposes a mapping of future research on how to move forward from mere associations to robust molecular data that will allow an accurate profiling of ILs in turn enabling evidence-based consultancy and decision making when addressing RIF patients.

Abstract
INTRODUCTION . Apoptosis is a key process during normal trophoblastic development and, consequently, the whole gestation. However, in trophoblastic differentiation in spontaneous abortions apoptosis has been hardly investigated. Therefore, the aim of the study was to investigate the correlation between apoptotic frequency in trophoblast and spontaneous abortion incidences. MATERIAL AND METHODS A total of 72 trophoblastic tissue samples were immunohistochemically examined. 42 of 72 derived from first-trimester spontaneous abortions and the remaining 30 from elective terminations during the same trimester of pregnancy. TUNEL assay and M30 marker were used for apoptosis evaluation by immunohistochemistry. RESULTS Comparative study of tissues from spontaneous abortions and elective pregnancy terminations demonstrated increased expression of both apoptotic markers in tissues derived from spontaneous abortions compared to normal pregnancies. In addition, statistical analysis correlated maternal age and gravidity with increased spontaneous abortion incidences. Moreover, both M30 and TUNEL staining were significantly correlated with maternal age and primigravidity in spontaneous abortion cases. CONCLUSIONS Our data proved that elevated apoptotic activity during the first pregnancy trimester is clearly involved in spontaneous abortions. Moreover, two well-established apoptotic markers revealed high statistical significance in the evaluation of post-abortive tissues.

Abstract
The present study investigated the potential nephro- and pneumoprotective effect of silibinin (Si) after hepatic ischemia-reperfusion (I/R) injury, by measuring pro-inflammatory factors. Sixty-three rats were randomly assigned into three groups, as follows: (a) the sham group (n=7 rats), subjected to opening and closing the abdomen; (b) the control group (n = 28 rats), subjected to 45-min hepatic ischemia followed by reperfusion; and (c) the silibinin group (n=28), subjected to 45-min hepatic ischemia followed by intravenous administration of lyophilized SLB-HP-β-CD before reperfusion. Control and silibinin groups were further subdivided into time-point groups, according to the duration of reperfusion. TNF-α, IL-6 and MCP-1 expressions were determined immunihistochemically and by qrT-PCR at each time-point. Kidney TNF-α expression was significantly lower at 180 and 240 min, while lung TNF-α expression was significantly lower at 240 min. Comparison between the control and Si group at the same time-points, showed very strong evidence of difference at 240 min, with the levels of IL-6 shifting towards lower values in the Si group. Finally, we found a high MCP-1 expression after 120 min. We conclude that hepatic I/R injury remotely increases proinflammatory mediators in the kidney and lung, whereas silibinin shows a time-dependent nephro- and pneumoprotective effect.

Abstract
BACKGROUND Major liver resection may compromise gut-barrier function, increasing the risk of postoperative infectious complications. The aim of the present experimental study was to compare the effect of the laparoscopic versus the open technique for major liver resection on integrity as well as inflammatory and immune responses of the gut barrier. METHODS Wistar rats were subjected to open 70% hepatectomy (group H), laparoscopic 70% hepatectomy (group LH), sham operation (group S) or no intervention (group C). At various timepoints (1 hour-1 week) after operation, ileal tissue was excised for oxidative state assessment (TBARS levels), histopathologic examination, histomorphometric analysis, immunohistochemical assessment of the mitotic and apoptotic activity, and tissue expression of inflammatory (interleukin-6, tumor necrosis factor-α, nuclear factor-κB and vascular cell adhesion molecule-1) and immune response biomarkers (CD4+ and CD8+ T-lymphocytes) of the intestinal mucosa. RESULTS No changes were noted in oxidative state. The histopathologic profile was less deteriorated in group LH compared to group H. Intestinal mucosa atrophy was less intense in group LH compared to group H and was related to an equally compromised crypt cell mitotic activity. Tissue overexpression of interleukin-6, tumor necrosis factor-α, nuclear factor-κΒ, vascular cell adhesion molecule-1, CD4+, and CD8+ T-lymphocytes was less pronounced in group LH compared to group H. CONCLUSION The employment of the laparoscopic technique for major liver resection in the rat attenuated disruption of the gut barrier compared to the open procedure. This was related to less pronounced inflammatory and immune responses of the intestinal mucosa.

Abstract
PURPOSE The protective effect of silibinin on kidney and lung parenchyma during hepatic ischemia/reperfusion injury (IRI) is explored. METHODS Sixty-three Wistar rats were separated into three groups: sham; control (45 min IRI); and silibinin (200 μL silibinin administration after 45 min of ischemia and before reperfusion). Immunohistochemistry and real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) were used to evaluate the expression levels of MMP2, MMP3, MMP9, and TIMP2 on kidney and lung. RESULTS Comparing sham vs. control groups, confirmed that hepatic IRI increased both renal and lung MMP2, MMP3, MMP9 and TIMP2 expressions starting at 180 min (p<0.001). Comparison of the control vs. silibinin groups showed a statistically significant decrease in the expression levels of MMP2, MMP3, and MMP9 and increase of TIMP2 in kidney and lung parenchyma. The starting point of this decrease was at 120 min after reperfusion, both for kidney and lung parameters, and it was statistically significant at 240 min (p<0.001) for kidney, while silibinin showed a peak of lung protection at 180 min after hepatic reperfusion (p<0.001). CONCLUSIONS Hepatic IRI causes distant kidney and lung damage, while a statistically significant protective action, both on kidney and lung parenchyma, is conveyed by the intravenous administration of silibinin.

Abstract
The impact of the pandemic outbreak associated with coronavirus 2019 disease (COVID-19) on pregnant women is of interest to obstetricians and gynecologists due to the vulnerability of this target group. In pregnant women and their infants, an exceptional clinical management is warranted. Current epidemiological findings provide information regarding the effects of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on pregnant patients and potential adverse perinatal outcomes. Overall, these findings are a strong indication that an increased antenatal surveillance for pregnant patients infected with COVID-19 is warranted. The aim of the present narrative review was to summarize the data obtained to date regarding the health of women during pregnancy, as well as that of the fetus associated with the risk of severe infection due to COVID-19. The present review aimed to provide further insight into the effects of this pandemic on pregnancy, also providing the experience of the authors on this matter as an example.

Abstract
OBJECTIVES We investigated the positive effect of silibinin after IV administration as silibinin-hydroxypropyl-β-cyclodextrin lyophilized product, by measuring gene expression and liver tissue protein levels of tumor necrosis factor-α, interleukin-6, monocyte chemoattractant protein-1, matrix metalloproteinases matrix metalloproteinases and tissue inhibitor of matrix metalloproteinases-2. METHODS 63 Wistar rats of age 13.24±4.40 weeks underwent ischemia/reperfusion (I/R) injury of the liver. The animals were randomized into three groups: Sham (S; n = 7); Control (C; n-28); silibinin (Si; n-28). The C and Si groups underwent 45 min ischemia. Si received silibinin-hydroxypropyl-β-cyclodextrin intravenously immediately before reperfusion at a dose of 5 mg/kg. Both groups were further divided into 4 subgroups, based on euthanasia time (i.e., 60, 120, 180 and 240 min). KEY FINDINGS qRT-PCR results confirmed the statistically significant reduction of the expression of the pro-inflammatory factors at 240 min after I/R injury (tumor necrosis factor-α: P < 0.05; MCR1: P < 0.05) and matrix metalloproteinases (matrix metalloproteinases 2: P < 0.05; matrix metalloproteinases 3: P < 0.05) and the increase of tissue inhibitor of matrix metalloproteinases-2 in liver tissue in the Si group. Moreover, results of immunohistochemistry levels confirmed that at 240 min pro-inflammatory factors (tumor necrosis factor-α: P < 0.05; MCR1: P < 0.05) and matrix metalloproteinases ( matrix metalloproteinases 2: P < 0.05; matrix metalloproteinases 3: P < 0.05) had a statistically significantly lower expression in the Si group while tissue inhibitor of matrix metalloproteinases-2 had a higher expression. CONCLUSIONS Silibinin may have a beneficial effect on the protection of the liver.

Abstract
Propolis is a resinous substance produced by bees that exhibits antimicrobial, immunostimulatory and antioxidant activity. Its use is common in functional foods, cosmetics and traditional medicine despite the fact that it demonstrates low extraction yields and inconsistency in non-toxic solvents. In this work, a new encapsulation and delivery system consisting of liposomes and cyclodextrins incorporating propolis polyphenols has been developed and characterized. The antioxidant, antimutagenic and antiaging properties of the system under normal and UVB-induced oxidative stress conditions were investigated in cultured skin cells and/or reconstituted skin model. Furthermore, the transcript accumulation for an array of genes involved in many skin-related processes was studied. The system exhibits significant polyphenol encapsulation efficiency, physicochemical stability as well as controlled release rate in appropriate conditions. The delivery system can retain the anti-mutagenic, anti-oxidative and anti-ageing effects of propolis polyphenols to levels similar and comparable to those of propolis methanolic extracts, making the system ideal for applications where non-toxic solvents are required and controlled release of the polyphenol content is desired.

Abstract
Introduction we present a rat experimental model used to evaluate the possible reduction in the extent of pancreatic tissue injury in acute pancreatitis cases, after administration of eugenol. Methods one hundred and twenty Wistar rats were used, which were randomly assigned in 3 groups: sham (n=20), control (n=50) and eugenol (n=50). Acute pancreatitis was induced by biliopancreatic ligation in the control and eugenol groups, but not in the Sham group. In the eugenol group, eugenol was administered per-os. Five histopathological parameters, such as edema, inflammatory infiltration, duct dilatation, hemorrhage and acinar necrosis were evaluated. Results at 72 h from acute pancreatitis induction, the total histological score was diminished in the eugenol group (p<0.0005) and duct dilatation and inflammatory infiltration were reduced compared to the control group (p<0.05). In addition, at 72 h, eugenol reduced pancreatic myeloperoxidase activity (p<0.0005). Conclusion eugenol, a highly free radical scavenger agent, may have a preventive role in acute pancreatic injury, as it was evident in our rat experimental model.

Abstract
BACKGROUND Laparoscopic liver resection offers a safe and feasible option primarily for the excision of hepatic neoplasms. Timely recovery of liver volume is a key factor for improving prognosis and post-operative mortality of patients undergone liver resection. The aim of the present study was to compare liver regeneration after laparoscopic over open partial hepatectomy. METHODS Wistar rats were subjected to laparoscopic 70% hepatectomy (group LAP-HEP), open 70% hepatectomy (group HEP), sham operation (group Sham) or no intervention (group Control). At various timepoints following operation (1 h-2 weeks), the liver was excised to assess relative liver weight, thiobarbituric acid reactive substances (TBARS) levels, mitotic activity, tissue expression of Nuclear Factor-κB (NFκB), Intercellular Adhesion Molecule-1 (ICAM-1) and Vascular Cell Adhesion Molecule-1 (VCAM-1) and the histopathologic profile. RESULTS No differences were seen in relative liver weight between hepatectomy groups. Mitotic index was increased in all operative study groups, being higher in group LAP-HEP than in group HEP. TBARS levels were higher in group LAP-HEP compared to group HEP. NFκB and VCAM-1 tissue expression scores were increased in all operative study groups with VCAM-1 being higher in group HEP, while ICAM-1 was overexpressed only in hepatectomy groups. Mild histopathologic lesions were noted in hepatectomy groups with the histopathologic score being higher in group HEP (24 h). CONCLUSIONS Laparoscopic liver resection enhanced hepatocyte mitotic activity which was accompanied by mild oxidative stress and a less pronounced local inflammatory response and tissue injury to that of the open technique.

Abstract
BACKGROUND We investigated the protective effect of silibinin on rat liver and kidney after hepatic inschemia/reperfusion (I/R) injury. METHODS AND MATERIALS Sixty three male Wistar-type rats (median age 13 weeks; average weight 314 g) were subjected to I/R injury of the liver. They were randomly divided into three groups: Sham (n = 7), Control (C, n = 28) and Silibinin (Si, n = 28). The last group received intravenously silibinin. The C and Si groups were each subdivided in four subgroups according to euthanasia times (i.e., 60, 120, 180, 240 min). We assessed expression of caspase-3 and TUNEL assay, and biochemical and histological parameters. RESULTS At 240 min, expression of caspase-3 and TUNEL assay were statistically significantly lower in the Si compared to the C group for both liver and kidney. SGOT and SGPT were also statistically significantly lower in the Si than in the C group at all time points. Histological parameters of the liver were also improved in the Si group. CONCLUSION Silibinin was found to exhibit a protective effect on liver and kidney after hepatic I/R injury. The present results are encouraging for further studies and future clinical application.

Abstract
Corticotropin Releasing Factor (CRF) neuropeptides coordinate the stress response via two distinct membrane receptors (CRF-Rs). We have previously shown expression of both CRF-Rs in human breast cancer tissues. In the present study, we examined in vitro using the MCF-7 cell line model, the regulation of CRF-Rs expression and their signaling in hormone-dependent breast cancer growth. Our findings show that similarly to breast cancer biopsies, the predominant receptor type expressed in the cell line is CRF-R2α. The transcription of CRF-R1 and CRF-R2 is up and down-regulated respectively by exposure to estradiol (E2); however this effect seems not to be exerted at the level of promoter gene methylation, although in human breast cancer specimens, CRF-R1 methylation was found to be positively associated with the presence of steroid hormone receptors. Finally, we showed that specific activation of CRF-R2 increased the migration of MCF-7 cells and potentiated an estrogen-inducing effect. Our data support an involvement of CRF-R signaling in breast cancer pathophysiology via a regulatory steroid-hormone interplay.

Abstract
In the present study, we aimed to examine the antioxidant, antiaging and photoprotective properties of Greek honey samples of various botanical and geographical origin. Ethyl-acetate extracts were used and the and the total phenolic/flavonoid content and antioxidant capacity were evaluated. Honey extracts were then studied for their cytoprotective properties against UVB-induced photodamage using human immortalized keratinocytes (HaCaT) and/or reconstituted human skin tissue models. Specifically, the cytotoxicity, oxidative status, DNA damage and gene expression levels of specific matrix metalloproteinases (MMPs) were examined. Overall, the treatment of HaCaT cells with honey extracts resulted in lower levels of DNA strand breaks and attenuated the decrease in cell viability following UVB exposure. Additionally, honey extracts significantly decreased the total protein carbonyl content of the irradiated cells, however, they had no significant effect on their total antioxidant status. Finally, the extracts alleviated the UVB-induced up-regulation of MMPs-3, -7 and -9 in a model of reconstituted skin tissue. In conclusion, honey extracts exhibited significant photoprotective and antiaging properties under UVB exposure conditions and thus could be further exploited as promising agents for developing novel and naturally-based, antiaging cosmeceutical products.

Abstract
Background Glycoprotein non-metastatic melanoma B (GPNMB) is a transmembrane glycoprotein with various roles in inflammation regulation, tissue remodeling and oncogenesis. Clinical situations implicating alterations in its expression include ischemic injury, cirrhosis and fatty liver disease amongst other. We examine its expression in hepatic and renal tissue following hepatic ischemia-reperfusion (I/R) in a rat model, with and without intravenous silibinin administration, as a silibinin-hydroxypropyl-β-cyclodextrin lyophilized complex (SLB-HP-β-CD). Methods Sixty-three Wistar rats were divided into 3 groups: sham group (virtual intervention; 7 animals), control (C) group (45 min of ischemia, followed by reperfusion and euthanasia at 60, 120, 180 and 240 min; 28 animals equally divided), and silibinin (Si) group (45 min of ischemia, intravenous administration of SLB-HP-β-CD, reperfusion and euthanasia at the same time points; 28 animals equally divided). GPNMB expression was examined in liver and kidney tissue. Results GPNMB expression was significantly increased following hepatic I/R in the control group, in kidney tissue, in a time dependent manner. In the silibinin group, GPNMB expression significantly decreased with time compared to the control group in both liver and kidney tissue (P<0.05). Conclusions Hepatic I/R causes increase of GPNMB levels both in liver and kidney tissues, which may reflect tissue injury. Silibinin seems to act protectively on both liver and kidney, and can be potentially used as a therapeutic approach against hepatic I/R injury.

Abstract
BACKGROUND/AIM This study investigated the anti-inflammatory effect of apigenin in an experimental model of acute pancreatitis. Inflammatory response was reflected by tissue expression of the cytokine TNF-α coupled with histological examination. MATERIALS AND METHODS Wistar rats were divided into three groups: Sham-group animals underwent laparotomy only, without any other interventions. Control-group animals underwent laparotomy and bilio-pancreatic duct ligation to induce pancreatitis without apigenin administration. Apigenin group animals were further treated with apigenin. Euthanasia was performed at 6, 12, 24, 48 and 72 h post-operatively. RESULTS Over-expression of TNF-α in relation to postoperative time was observed in the control group (p<0.001). In the apigenin group, under-expression of TNF-α in relation to postoperative time was observed (p<0.013). At 72 h, apigenin reduced pancreatic TNF-α expression and prevented pancreatic necrosis. CONCLUSION Apigenin slows progression and reduces severity of acute pancreatitis. Apigenin may serve as an adjunct to a more successful therapeutic strategy in acute pancreatitis.

Abstract
PURPOSE To provide a global scale report on a representative sample of the clinical embryology community depicting the practice of discarding supernumerary IVF embryos. METHODS A web-based questionnaire titled "Anonymous questionnaire on embryo disposal practices" was designed in order to ensure anonymous participation of practicing clinical embryologists around the world. RESULTS During a data collection period of 8 months, 703 filled-in questionnaires from 65 countries were acquired. According to the data acquired, the majority of practitioners, dispose of embryos by placing them directly in a trash can strictly dedicated for embryo disposal for both fresh and frozen cycles (39% and 36.7% respectively). Moreover, 66.4% of practitioners discard the embryos separately-case by case-at different time points during the day. Over half of embryologists (54%) wait until day 6 to discard the surplus embryos, while 65.5% do not implement a specially allocated incubator space as a designated waiting area prior to disposal. The majority of 63.1% reported that this is a witnessed procedure. The vast majority of embryologists (93%) do not employ different protocols for different groups of patients. Nonetheless, 17.8% reported the request to perform a ceremony for these embryos. Assessing the embryologists' perspective, 59.5% of participants stated that the embryology practice would benefit from a universally accepted and practiced protocol. CONCLUSION(S) This study uniquely provides insight into global embryo disposal practices and trends. Results highlight the divergence between reported practices, while indicating the significance on standardization of practice, with embryologists acknowledging the need for a universally accepted protocol implementation.

Abstract
We present a case of spontaneous undifferentiated/unclassified sarcoma, of a pleomorphic subtype formerly known as malignant fibrous histiocytoma (UPS/MFH), arising from the pancreas of a laboratory rat. The mass was excised after laparotomy from a 6-month-old female laboratory Wistar rat. It presented a giant multilobulated mass of irregular shape, which had arisen from the pancreas and occupied almost the entire peritoneal cavity. Histologically the tumor was characterized by a highly variable morphological pattern, with frequent transitions from storiform to pleomorphic areas. An extensive immunohistochemical examination revealed no specific lines of differentiation. Immunohistochemical positivity was observed only to MIB-1 (high Ki-67 proliferation index), vimentin and CD68 antibodies. The diagnosis was compatible with UPS/MFH. To the best of our knowledge, the present case is the first report of a spontaneous primary UPS/MFH arising from the pancreas of a laboratory rat.

Abstract
The aim of this study was to assess the antioxidant, photoprotective, and antiaging effects of Greek propolis. Propolis was subjected to n-heptane or methanol extraction. Total phenolic/flavonoid content and antioxidant potential were determined in the extracts. Promising extracts were evaluated for their cytoprotective properties using human immortalized keratinocyte (HaCaT) or reconstituted human skin tissue following exposure to UVB. Assessment of cytotoxicity, DNA damage, oxidative status, and gene/protein expression levels of various matrix metalloproteinases (MMPs) were performed. The propolis methanolic fractions exhibited higher total phenolic and flavonoid contents and significant in vitro antioxidant activity. Incubation of HaCaT cells with certain methanolic extracts significantly decreased the formation of DNA strand breaks following exposure to UVB and attenuated UVB-induced decrease in cell viability. The extracts had no remarkable effect on the total antioxidant status, but significantly lowered total protein carbonyl content used as a marker for protein oxidation in HaCaT cells. MMP-1, -3, -7, and -9, monitored as endpoints of antiaging efficacy, were significantly reduced by propolis following UVB exposure in a model of reconstituted skin tissue. In conclusion, propolis protects against the oxidative and photodamaging effects of UVB and could be further explored as a promising agent for developing natural antiaging strategies.

Abstract
Background: Improvement of the management of pancreatic cancer requires a better
understanding of the genetic and molecular changes responsible for the
development of the disease. The family of p21-activated kinases (PAKs) and
especially PAK1 appears to mediate many cellular processes that contribute
to the development and progression of pancreatic cancer, but the clinical
relevance of PAK1 expression with the disease still remains unclear. Aim of
the study was to assess the clinical value and the potential prognostic
significance of PAK1 in pancreatic adenocarcinoma. Methods: We investigated the relationship between the PAK1 expression and the clinical
and histopathologic characteristics of pancreatic cancer patients and the
potential significance of PAK1 on survival. We examined tissue samples from
51 patients operated for pancreatic cancer. PAK1 expression was investigated
with immunohistochemistry and correlated to clinicopathological
parameters. Results: PAK1 was detected in all tumor samples and high expression was found in most
patients. High PAK1 expression was also associated with younger age and
well-differentiated tumors, but no association was found between PAK1
expression and Tumor-Node-Metastasis stage as well as deceased or alive
status on follow-up. Moderate to high PAK1 expression favored higher 6-month
and 1-year survival and low PAK1 expression 2-year survival but without
statistical significance. Conclusions Our results indicate that PAK1 could potentially be used as a prognostic
marker in pancreatic cancer. Further studies could clarify whether
utilization of PAK1 in therapeutic protocols for the treatment of pancreatic
cancer will render them more effective.

Abstract
Aim: Polymorphous low grade adenocarcinoma of the salivary glands (PLGA) is a low grade neoplasm that predominantly occurs in the minor salivary glands. In this site is amenable to biopsy and histologic diagnosis. However, experience with cytological findings in these tumors is limited. We describe the cytology of this entity. Experimental design: Touch imprint cytology of a primary parotid PLGA is specified and correlated with histology. Results: Smears were hypercellular showing branching papillae, sheets and clusters of uniform cells with bland nuclei, dispersed chromatin and no nucleoli. The cells had a scant to moderate amount of eosinophilic cytoplasm. They formed tubular structures containing hyaline globules. Conclusions. The cytologic differential diagnosis of PLGA includes adenoid cystic carcinoma, pleomorphic adenoma, and monomorphic adenoma. PLGA should be considered in the differential diagnosis of head and neck tumors, where the cytology suggests on of the above mentioned tumors, even when the clinical findings (involvement of a major salivary gland, lymph node metastasis) is not typical of PLGA.

Abstract
The aim of this paper is to highlight the symptomatology in three Conium maculatum intoxication incidents, one of which was fatal. A number of studies were reviewed in order to update and summarize the relevant literature on the incidence, sociodemographic variables, method of poisoning, pathophysiology, diagnosis, variables associated with survival and fatality, management, and treatment of C. maculatum intoxication as well as the biosynthesis and biological effects of poison hemlock alkaloids. Results show that hemlock poisoning is relatively rare, although incidence varies in different regions, despite its worldwide distribution. Hemlock poisoning is more common in European and especially Mediterranean countries. The majority of the patients are adult males over 38 years of age. The clinical course of hemlock poisoning includes neurotoxicosis, tremor, vomiting, muscle paralysis, respiratory paralysis/failure, rhabdomyolysis, and acute renal failure. The therapeutic management focuses on absorption reduction, close observation for complications, and supportive therapy (especially for respiration). Acute occurrence is severe and life-threatening, but the survival rate is high if treatment is provided promptly. Recovery is rapid, generally taking only a few days.

Abstract
Aim: Breast cancer is a frequent cause of death among women with gynaecologic malignancies despite the introduction of combination chemotherapy. There is therefore a need for new therapeutic strategies for patients with breast cancer, such as cellular immunotherapy. In this immunohistochemical study we analyzed the epithelial expression of major histocompatibility complex (MHC) class II (HLA-DR) on atypical and malignant primary mammary epithelial cells, as well as the magnitude of the stromal T lymphocytes (T4 subset) at the tumor site. Experimental design: The study was carried out retrospectively in tumor tissue from 82 patients with mammary lesions (31 cases of atypical ductal hyperplasia -ADH-, 12 cases of ductal carcinoma in situ –DCIS- and 39 cases of infiltrating ductal carcinoma not otherwise specified -IDC-NOS). Medullary carcinomas were not included in our investigation. Material used had been formalin fixed and paraffin embedded. Results: HLA class II (DR) was expressed in 20 of 31 ADHs (64.5%), in 4 of 12 DCISs (33.3%), and in 10 of 39 IDC-NOSs (25.6%). CD4 was expressed in 9 of 31 ADHs (29%), in 5 of 12 DCISs (42%), and in 26 of 39 IDCNOSs (67%). Conclusions: The results showed decreased epithelial expression of HLA class II (DR) and increased stromal expression of CD4, as the lesion progressed to malignancy. Gradual loss of epithelial HLA class II expression might be a manifestation of cellular differentiation from the atypical form versus the malignant one, signaling simultaneously a selective effect on the response capacity of the immune system.

Abstract
Oocyte freezing for 'social reasons' refers to women of reproductive age who are aiming to prolong, protect and secure their fertility. The term emerged to describe application of the highly promising technique, namely vitrification on oocytes retrieved through controlled ovarian stimulation (COS) from women intending to preserve their fertility for social reasons. These women opt to cryopreserve their oocytes at a point in their life when they need to postpone childbearing on the grounds of so called 'social' reasons. These reasons may include a highly driven career, absence of an adequate partner, financial instability, or personal reasons that make them feel unprepared for motherhood. This is a sensitive and multifaceted issue that entails medical, bioethical and socio-psychological components. The latest trend and the apparent increase noted on oocyte freezing for 'social reasons' has prompted our team of fertility specialists, embryologists, obstetricians, gynecologists and psychologists to proceed with a thorough, critical and all-inclusive comprehensive analysis. The wide range of findings of this analysis involve concerns of embryology and epigenetics that shape decisions made in the IVF laboratory, issues regarding obstetric and perinatal concerns on the pregnancy concluding from these oocytes and the respective delivery management and neonatal data, to the social and bioethical impact of this trend's application. This literature review refers to matters rising from the moment the 'idea' of this option is 'birthed' in a woman's thoughts, to proceeding and executing it clinically, up until the point of the pediatric follow up of the children born. We aim to shed light to the controversial issue of oocyte freezing, while objectively exhibit all aspects regarding this complex matter, as well as to respectfully approach how could the prospect of our future expectations be shaped from the impact of its application.

Abstract
BACKGROUND Remote kidney damage is a sequel of hepatic ischemia-reperfusion (I/R) injury. Silibinin is the main ingredient of the milk thistle plant seed extract with known antioxidant and hepatoprotective activity. Our study investigates the nephroprotective potential of intravenously administered silibinin, as a lyophilized SLB-hydoxypropyl-beta-cyclodextrin product, in hepatic I/R injury. MATERIAL AND METHODS 63 Wistar rats were divided into three groups: Sham (virtual intervention); Control (45 min ischemia and reperfusion); and Silibinin (200 μL intravenous silibinin administration after 45 min of ischemia). Kidney tissues were collected to determine TNF-α, M30 and histopathological changes at predetermined time intervals. RESULTS Comparing Sham vs. Control groups, proved that hepatic I/R injury increased renal TNF-α and M30 expression. Deterioration was observed in hyperemia/filtration of renal parenchyma and tubules, cortical filtration, tubular necrosis and edema (tissue swelling index). Intravenous silibinin administration and comparison of the Control vs. Silibinin groups showed a statistically significant decrease in TNF-α levels at 240 min following I/R (p < 0.0001), and in M30 at 180 min (p = 0.03) and 240 min (p < 0.0001). Renal parameters have significantly decreased in: hyperemia/filtration of renal parenchyma at 120 min (p = 0.003), 180 min (p = 0.0001) and 240 min (p = 0.0002); hyperemia/filtration of renal tubules at 120 min (p = 0.02), 180 min (p = 0.0001) and 240 min (p = 0.0005); cortical filtration (240 min - p = 0.005); tubular necrosis (240 min - p = 0.021); and edema (240 min - p = 0.001). CONCLUSION Our study confirms that hepatic I/R injury causes remote renal damage while the intravenous administration of silibinin leads to statistically significant nephroprotective action.

Abstract
PURPOSE Kisspeptins are produced by the KISS1 gene and have tumor-suppressing and anti-metastatic properties. Our aim was to study the expression of KISS1 and its receptor, KISS1R, in colorectal cancer. METHODS KISS1 and KISS1R expression was detected using immunohistochemistry in malignant tissue samples from 66 patients (34 men, 32 women) with colorectal adenocarcinoma. In total, 74 tumor samples were studied, 57 samples from primary tumors and 17 samples from liver metastases. KISS1 and KISS1R levels were associated with various clinicopathological parameters and survival data. RESULTS KISS1 expression was higher in primary tumors with advanced stage (III or IV) and in those with infiltrated lymph nodes. KISS1R expression was higher in primary tumors with distant metastases. No significant differences were detected between primary and metastatic tumors regarding KISS1 and KISS1R levels. Furthermore, patients with high KISS1R levels had longer overall survival. CONCLUSIONS KISS1 and KISS1R expression is higher in advanced colorectal cancers and high KISS1R levels are associated with better prognosis in colorectal cancer.

Abstract
Purpose/aim: To examine with immunohistochemical assay MTA1 protein expression levels in pancreatic cancer tissues defining its prognostic value. MATERIAL AND METHODS The specimens derived from 51 patients who underwent surgery. The levels of MTA1 protein were compared with the age of the patients, their survival, and prognosis. Also, we studied clinical and histopathological factors such as the degree of tumor differentiation and its stage in correlation with MTA1 protein levels. In parallel, there was correlation between the expression of the ΜΤΑ1 protein and the aforementioned factors regarding survival rate. Furthermore, we independently correlated the patient's survival in relation to whether they had undergone adjuvant chemotherapy or not. RESULTS It has been found to be low, moderate, or high expression of MTA1 levels in 48 out of 51 cancer tissues. Specifically, 49.0% of patients had low expression, 33.3% moderate, and 11.8% high expression of MTA1. Regarding the expression of MTA1 protein in correlation with various clinical and histopathological factors, a statistically significant correlation was observed with the degree of differentiation (p = 0.0068) and with the stage of the disease (p = 0.0173), but not with survival (p = 0.0740) or the age of them (p = 0.1547). Finally, it was found that overexpression of the MTA1protein is a prognostic factor for shorter survival in patients with pancreatic cancer (average 4.67 ± 0.95 months). CONCLUSIONS MTA 1 protein may constitute an important prognostic marker in pancreatic cancer and could improve prognosis and treatment.

Abstract
BACKGROUND The aim of the present study was to microscopically assess the tissue-sparing potential of contemporary radiofrequency-assisted liver resection (RF-LR) techniques. METHODS Twenty-four pigs were subjected to either (1) partial hepatectomy (PH) using the sequential-coagulate-cut (SCC) technique (group SCC, n = 6) using a monopolar electrode, the technique using the bipolar electrode Habib-4X (group H, n = 6) or the "crush-clamp" technique (group CC, n = 6); or (2) sham operation (group Sham, n = 6). At 48 h post-operation, liver parenchyma proximal to the ablation rim was excised for histopathologic examination and immunohistochemical assessment of apoptosis (antibody M30) and inflammatory response (antibodies IL-6, TNFα and NFκB). RESULTS Histopathologic index increased from the 1st to the 4th , the 1st to the 2nd or only the 1st cm from the inner margin of the ablation rim in group SCC, H or CC, respectively. The index was higher in group SCC compared to the other groups. Tissue expression of M30, IL-6, TNFα and NFκB increased in all PH groups, being higher and more expanded in group SCC, H, SCC and SCC, respectively. CONCLUSIONS RF-LR techniques had variable microscopically assessed tissue-sparing effect. The Habib-4X proved to be less injurious compared to the SCC Belgrade technique regarding the severity and extent of tissue damage proximal to the ablation rim.

Abstract
PURPOSE To evaluate remnant liver tissue damage in a pig model of radiofrequency (RF)-assisted liver resection employing either the sequential coagulate cut (SCC) Belgrade technique using a monopolar RF electrode or the one using the bipolar Habib-4x device. METHODS Sixteen pigs underwent either a) resection of part of the left lateral and left median hepatic lobes employing the SCC (SCC group), the Habib-4X (H group) or the "crushclamp" technique (CC group) or b) sham operation (Sham group). Forty-eight hours later, tissue specimens were excised from the right lateral hepatic lobe for histopathological examination and immunohistochemical assessment of tissue injury, mitosis and inflammation. RESULTS Histopathologic lesions, apoptotic activity, HSP 40 and TNFα expression were more intense, while mitotic activity was less prominent in the SCC group technique compared to H group. Comparison between CC and H groups suggested the pivotal role of partial hepatectomy (PH) per se in the changes noted in H group. CONCLUSION The Habib-4X liver resection technique proved to be less injurious in the remnant liver tissue after PH compared to the SCC technique.

Abstract
BACKGROUND Thyroid transcription factor-1 (TTF-1) has been considered a sensitive marker for thyroid and lung tumors. Recent data have shown that a wide range of neoplasms may express TTF-1. CASE SERIES We performed an immunohistochemical study in a case series of 42 urothelial carcinomas (UCs) on tissue microarrays sections, in order to investigate how often UCs express the TTF-1 protein and the diagnostic utility of this marker. In addition, we sought to determine by immunohistochemistry if there is an association between TTF-1 expression and the expression of specific basal-like or luminal markers. Five out of the 42 cases (11.9 %) were positive for TTF-1. Three positive tumors concerned non-invasive papillary UCs. There was no association between TTF-1 expression and tumor grade (χ2, p =0.419), stage (χ2, p =0.550) or cytokeratin 5/6 (χ2, p =0.330), cytokeratin 20 (χ2, p =0.995) and estrogen receptors expression (χ2, p =0.268). CONCLUSIONS UCs may show TTF-1 expression and pathologists should be aware of this phenomenon in order to avoid misdiagnosis, notably in metastatic disease. HIPPOKRATIA 2017, 21(3): 154-157.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is one of the most common malignant tumors. Despite the important progress observed in liver surgery, the survival rates are discouraging. The aim of this study was to investigate the expression of autotaxin in hepatocellular carcinoma. MATERIALS AND METHODS Liver tissues from 28 human hepatocellular carcinomas were evaluated for the expression of autotaxin by immunohistochemistry. The gender, age, histological grade, lymphovascular invasion, number of tumors, levels of serum alpha-fetoprotein (aFP), presence of liver cirrhosis, hepatitis, surgery and survival rates were recorded. RESULTS Immunohistochemistry confirmed the expression of autotaxin in hepatocellular carcinoma. The histological grade seems to be the only independent predictor of stronger autotaxin expression, as significantly higher levels of autotaxin were detected in histological grades II and III. In addition, levels of autotaxin seem to be the most important independent prognostic factor related to poor survival. There was an eight-fold higher risk of death in patients with high levels of autotaxin compared to patients with low levels. CONCLUSIONS Autotaxin expression in hepatocellular carcinoma could be of great importance. High autotaxin expression in HCC is detected in patients with histological grade II and III. Further, patients with elevated expression levels were found to possess an eight-fold higher risk of death. Autotaxin role in HCC should be further elucidated.
