Abstract
Melamine (ML) is a common environmental contaminant, commonly used in food fraud, representing a serious health hazard and jeopardizing human and animal health. Recently, nootkatone (NK), a naturally occurring sesquiterpenoid, has garnered considerable attention due to its potential therapeutic advantages. We investigated the potential mechanisms underlying the protective effects of NK against ML-induced liver injury in rats. Five groups were utilized: control, ML, NK10, ML-NK5, and ML-NK10. ML induced substantial hepatotoxicity, including considerable alterations in biochemical parameters and histology. The oxidative distress triggered by ML increased the generation of malondialdehyde (MDA) and nitric oxide (NO) and decreased levels of reduced glutathione (GSH), catalase (CAT), and superoxide dismutase (SOD) activities. In addition, decreased expression of nuclear factor-erythroid 2-related factor 2 (Nrf2) and increased nuclear factor kappa beta (NF-κB) expression levels were observed in hepatocytes, which indicated the occurrence of inflammatory changes following ML exposure. These alterations were alleviated by NK supplementation in a dose-dependent manner. The data revealed that the favorable effects of NK were attributed, at least in part, to its antioxidant and anti-inflammatory properties. Moreover, our results were supported by molecular docking studies that revealed a good fit and interactions between NK and antioxidant enzymes. Thus, the current study demonstrated that NK is a potential new food additive for the prevention or treatment of ML-induced toxicity.

Abstract
Circular RNAs (circRNAs) are a newly validated type of noncoding RNAs recently found to be deregulated in several human cancers. More accurate and specific noninvasive biomarkers are strongly needed for better diagnosis and prognosis of hepatocellular carcinoma (HCC). We performed a bioinformatics analysis to retrieve a novel panel of circRNAs potentially relevant to HCC. We examined their expression in the sera of 68 patients with HCC, 60 patients with chronic hepatitis C, and 36 healthy controls using quantitative polymerase chain reaction. We examined the performance characteristics of the selected circRNA biomarker panel in comparison with alpha-fetoprotein (AFP). In addition, we performed a survival analysis to correlate between their expression levels and patient survival. The circRNAs hsa_circ _00224 and hsa_circ _00520 showed a strong biomarker potential with relatively high sensitivities and specificities compared with AFP. The combined panel including the three circRNAs showed superior performance characteristics relative to those of AFP. The median follow-up period was 26 months. hsa_circ_00520 expression has been shown to be associated with relapse-free survival (P < 0.005). circRNAs hsa_circ_00156, hsa_circ_000224, and hsa_circ_000520 are novel potential biomarkers of high sensitivity and specificity, which could potentially be used in the diagnosis of HCC.

Abstract
With the advent of recent advances in molecular techniques and whole genome sequencing, we have come to know that the non-coding landscape (including non-coding RNAs, tRNAs and even telomeres) plays a major role in the regulation of cellular processes. Furthermore, the deregulation of this landscape has been found to contribute to and even bring about the pathogenesis of a large number of diseases. One of such diseases is diabetes mellitus (type 2 specifically) whose incidence rate and global burden is constantly increasing. Nutrition has been proven to be a key player in the development, onset and control of type 2 diabetes mellitus. Additionally, non-coding DNA based molecular markers are emerging as biomarkers of T2D, susceptibility, and perhaps dietary supplements can modulate non-coding DNA based markers expression and function in T2D management. In this review, we provide a brief overview of the developmental origins and genetics of type 2 diabetes mellitus, how each component of the non-coding landscape contributes to the development and progression of the disease and finally we discuss how dietary interventions modulate the non-coding landscape in T2D.

Abstract
Epigenetic changes in oncogenes and tumor-suppressor genes contribute to carcinogenesis. Understanding the epigenetic and genetic components of tumor immune evasion is crucial. Few cancer genetic mutations have been linked to direct correlations with immune evasion. Studies on the epigenetic modulation of the immune checkpoints have revealed a critical interaction between epigenetic and immune modulation. Epigenetic modifiers can activate many silenced genes. Some of them are immune checkpoints regulators that turn on immune responses and others turn them off resulting in immune evasion. Many forms of epigenetic inheritance mechanisms may play a role in regulation of immune checkpoints including: covalent modifications, noncoding RNA and histone modifications. In this review, we will show how the potential interaction between epigenetic and immune modulation may lead to new approaches for specific epigenome/immunome-targeted therapies for cancer.

Abstract
BACKGROUND The consequences of stroke must be assessed not only in terms of incidence and mortality rates, but also in terms of disability, which may persist long after the acute phase. Thrombolysis, if timely administered, can effectively reduce post-stroke disability. AIMS The economic model presented herein aims to evaluate, in eligible patients, the effects of alteplase on post-stroke disability and related costs over three-years. METHODS The economic analysis was developed on the basis of four key components: clinical outcomes from international trials, economic consequences extracted from cost of illness studies, regulatory data from national and international agencies, and national epidemiological data. A population-level model estimated the difference in disability costs between patients treated with standard care versus those receiving thrombolytic therapy within 4×5 h of acute ischemic stroke. The analysis covered 36 months from discharge. RESULTS Reduced costs related to post-stroke disability were observed in treated patients compared with those receiving standard care (control). The overall savings were €2330×15 per average patient: €1445×81 during the first 18 months, €362×25 between 18 and 24 months, and €522×09 in the 24-36 months period. The overall savings on 3174 Italian treated patients in 2013 were €7 395 907 over three-years. CONCLUSION Our study reveals that performing thrombolytic therapy in eligible patients improves economic outcomes compared with patients receiving standard care. This model is useful for decision makers, both within and outside of the Italian national context, as a tool to assess the cost-effectiveness of thrombolysis in both short- and long-term period.

Abstract
OBJECTIVES To examine the levels of sperm protamine free sulfhydryl or thiol (SH) groups and DNA denaturation (DD) in semen from fertile and infertile men.Methods. Semen samples were obtained from consecutive nonazoospermic men presenting for infertility evaluation (n = 66) and fertile men presenting for vasectomy (n = 10). The standard semen parameters (sperm concentration, motility, and morphology), sperm DD, and SH content were monitored. Sperm DNA integrity was evaluated by flow cytometry analysis of acridine orange-treated spermatozoa and expressed as the percentage of spermatozoa demonstrating denatured DNA. RESULTS The mean (+/- SE) levels of sperm SH groups and the percentage of spermatozoa with DD were significantly higher in the infertile men than in the fertile men (SH groups 1083 +/- 97 and 570 +/- 101 nmol/10(6) spermatozoa, respectively; and DD 21% +/- 1.7% and 8.9% +/- 1.9%, respectively). The levels of sperm SH groups and DD correlated positively (r = 0.53). Also, the levels of sperm SH groups and DD correlated negatively with the standard semen parameters. CONCLUSIONS Our data demonstrate that sperm SH content correlates positively with sperm DD and that significantly higher levels of sperm DD and SH content are found in infertile men than are found in fertile men. These data suggest that the enhanced susceptibility of sperm DNA to denaturation in infertile compared with fertile men may be associated with incomplete oxidation of the sperm SH groups.

Abstract
OBJECTIVE To evaluate the natural history of infertile couples in whom the man underwent varicocelectomy. DESIGN Retrospective study. SETTING University infertility clinic. PATIENT(S) 159 infertile couples. INTERVENTION(S) Microsurgical varicocelectomy. MAIN OUTCOME MEASURE(S) Standard semen parameters and pregnancy rates (assisted and unassisted). RESULT(S) Postoperative sperm concentration and motility increased significantly compared to before the varicocelectomy (28.9 +/- 3.0 vs. 22.5 +/- 2.1 x 10(6)/mL and 33.9 +/- 1.9 vs. 22.1 +/- 1.3%, respectively). Overall, 48% (76/159) of the couples achieved a spontaneous pregnancy at the mean of 30 months' follow-up. An additional 10% (16/159) and 11% (18/159) of couples achieved a pregnancy following intrauterine insemination and in vitro fertilization/intracytoplasmic sperm injection, respectively. Significantly higher spontaneous pregnancy rates were observed in couples in whom the man's initial sperm concentration was greater than or equal to 5 million sperm per milliliter compared to those in whom the man's initial sperm concentration was less than 5 million sperm per milliliter (61% vs. 8%, respectively). CONCLUSION(S) Our data demonstrate that, in couples in whom the man undergoes varicocelectomy for treatment of varicocele, close to 70% achieve a pregnancy. The initial sperm concentration is predictive of unassisted pregnancy outcome in this population.

Abstract
Recent reports have indicated the effectiveness of furosemide in inhibiting responses to inhaled allergen and in treating allergic conjunctivitis. In the present study furosemide was tested for its antiallergic potential using compound 48/80 induced paw edema and in vitro mast cell degranulation. Furosemide was found to significantly inhibit compound 48/80 paw edema and compound 48/80 induced histamine release. Furosemide was also found to inhibit histamine release during passive peritoneal anaphylaxis in rats. The results suggest that furosemide may be inhibiting the release of mediators of anaphylaxis from the mast cells.

Abstract
Iotrolan was investigated as a new contrast medium for hysterosalpingography. Fertility rates and side-effects were registered in a series of 108 consecutive patients. The results indicate a higher fertility rate after hysterosalpingography with iotrolan than after the use of other water-soluble contrast media but a lower fertility rate when compared to lipiodol. As for side-effects, the study indicates that the frequencies of low abdominal pain and vaginal bleeding after hysterosalpingography are equal for iotrolan and lipiodol but higher for other, water-soluble contrast media. A prospective, randomized study is recommended for the clarification of these aspects.
