Impact of the Type of Dialysis on Time to Transplantation: Is It Just a Matter of Immunity?

Background: Renal transplantation represents the therapeutic gold standard in patients with end stage renal disease (ESRD). Still the role of pre-transplant dialysis in affecting time to transplantation has yet to be determined. We wanted to verify whether the type of renal replacement therapy (hemodialysis vs.

Efficacy of a new combination of a microemulsion and oral supplementation for androgenetic alopecia: an interventional multicentric study.

Background: The aim of this study was to study new therapeutic options for the treatment of female and male androgenetic alopecia (AGA) and to assess the efficacy of a possible new coadjuvant oral and topical therapy, containing a complex of natural substances.

Methods: Sixty individuals affected by mild-to-moderate female and male AGA were enrolled in the study and underwent the oral and topical treatment with a microemulsion formulation for 6 months. At baseline and at 3- and 6-month follow-up, global photographs were taken and three expert operators evaluated photographs using the 7-point scale.

Intravenous Iron Replacement Therapy Improves Cardiovascular Outcomes in Hemodialysis Patients.

Background/aim: More than half of deaths among hemodialysis patients are due to cardiovascular disease. This study examined whether intravenous administration of ferric carboxymaltose (FCM) has an impact on cardiovascular events in iron-deficient hemodialysis patients.

Patients And Methods: We performed a retrospective study concerning patients undergoing hemodialysis in our center from September 2016 to December 2019.

A simple immunohistochemical bio-profile incorporating Bcl2 curbs those cases of invasive breast carcinoma for which an Oncotype Dx characterization is needed.

Aim: Our goal has been to evaluate the importance that the incorporation of Bcl2 in the ER/PGR/Her2/Ki67 bio-profile can have as predictor of the Oncotype Dx categories.

Material And Methods: 156 consecutive cases of HR+/Her2- pN0/1 primary breast carcinoma were sent to the Oncotype Dx test. Immunohistochemical determination of Bcl2/ER/PGR/Ki67/Her2 expression was evaluated for each case.

Short-term treatment with eicosapentaenoic acid improves inflammation and affects colonic differentiation markers and microbiota in patients with ulcerative colitis.

Patients with long-standing ulcerative colitis (UC) have an increased colorectal cancer (CRC) risk. In this pilot study we evaluated the effect of Eicosapentaenoic acid as free fatty acid (EPA-FFA) supplementation on mucosal disease activity, colonic differentiation markers and microbiota composition in UC patients. Twenty long-standing UC patients in stable clinical remission and with fecal calprotectin (FC) > 150 µg/g were enrolled (T0) and supplemented with EPA-FFA 2 g/daily for 90 days (T3).

Inflammation increases NOTCH1 activity via MMP9 and is counteracted by Eicosapentaenoic Acid-free fatty acid in colon cancer cells.

Aberrant NOTCH1 signalling is critically involved in multiple models of colorectal cancer (CRC) and a prominent role of NOTCH1 activity during inflammation has emerged. Epithelial to Mesenchymal Transition (EMT), a crucial event promoting malignant transformation, is regulated by inflammation and Metalloproteinase-9 (MMP9) plays an important role in this process. Eicosapentaenoic Acid (EPA), an omega-3 polyunsaturated fatty acid, was shown to prevent colonic tumors in different settings.

Setting reference values in trichology.

Background: In clinical trichology, reference values are often arbitrary. The difficulty in setting them up depends mostly on the presence of the androgenetic alopecia (AGA) genotype in subjects with clinically unapparent forms. Prepubertal children, who lack 5α-reductase (a real indicator of the AGA phenotype), might provide reference values independent from AGA.

High-throughput genotyping of high-risk Human Papillomavirus by MALDI-TOF Mass Spectrometry-based method.

A high-throughput matrix-assisted laser desorption ionisation-time of flight (MALDI-TOF) mass spectrometry (MS)-based method was here developed to genotype 16 high-risk human papillomavirus (HPV) types in cervical cytology specimens. This method was compared to a commercial kit, the Inno-LiPA HPV genotyping assay, which detects a broad spectrum of HPV types. HPV DNA was assessed by the two methods in a total of 325 cervical cytology specimens collected in PreservCyt® solution.

Suppression of p53 by Notch3 is mediated by Cyclin G1 and sustained by MDM2 and miR-221 axis in hepatocellular carcinoma.

To successfully target Notch receptors as part of a multidrug anticancer strategy, it will be essential to fully characterize the factors that are modulated by Notch signaling. We recently reported that Notch3 silencing in HCC results in p53 up-regulation in vitro and, therefore, we focused on the mechanisms that associate Notch3 to p53 protein expression. We explored the regulation of p53 by Notch3 signalling in three HCC cell lines HepG2, SNU398 and Hep3B.

Eicosapentaenoic acid free fatty acid prevents and suppresses colonic neoplasia in colitis-associated colorectal cancer acting on Notch signaling and gut microbiota.

Inflammatory bowel diseases are associated with increased risk of developing colitis-associated colorectal cancer (CAC). Epidemiological data show that the consumption of ω-3 polyunsaturated fatty acids (ω-3 PUFAs) decreases the risk of sporadic colorectal cancer (CRC). Importantly, recent data have shown that eicosapentaenoic acid-free fatty acid (EPA-FFA) reduces polyp formation and growth in models of familial adenomatous polyposis.

p53/mdm2 feedback loop sustains miR-221 expression and dictates the response to anticancer treatments in hepatocellular carcinoma.

Unlabelled: The overexpression of microRNA-221 (miR-221) is reported in several human cancers including hepatocellular carcinoma, and its targeting by tailored treatments has been proposed. The evidence supporting the role of miR-221 in cancer is growing and has been mainly focused on the discovery of miR-221 targets as well as on its possible therapeutic exploitations. However, the mechanism sustaining miR-221 aberrant expression remains to be elucidated.

Notch3 inhibition enhances sorafenib cytotoxic efficacy by promoting GSK3b phosphorylation and p21 down-regulation in hepatocellular carcinoma.

Sorafenib (Nexavar), a multiple kinase inhibitor, is the only clinically approved drug for patients with advanced HCC. However, its therapeutic success is limited by the emergence of drug resistance. Here we found that p21 and pGSK3βSer9 are major players in the resistance to sorafenib.

Van-Gogh-like 2 antagonises the canonical WNT pathway and is methylated in colorectal cancers.

Background: Aberrant activation of the canonical WNT signaling is a feature of colorectal cancer (CRC). Van-Gogh-like 2 (VANGL2) belongs to the non-canonical WNT pathway whose activation inhibits canonical WNT signaling. In this study, we investigated the role of VANGL2 and its epigenetic regulation in CRC.

Image cytometry: protocols for 2D and 3D quantification in microscopic images.

Microscopy-based imaging is booming and the need for tools to retrieve quantitative data from images is urgent. This book provides simple but reliable tools to generate valid quantitative gene expression data, at the mRNA, protein and activity level, from microscopic images in relation to structures in cells, tissues and organs in 2D and 3D. Volumes, areas, lengths and numbers of cells and tissues can be calculated and related to these gene expression data while preserving the 2D and 3D morphology.

Epidemiology of dermatophytoses: retrospective analysis from 2005 to 2010 and comparison with previous data from 1975.

Dermatophyte infections are extremely frequent worldwide and their epidemiological features vary according to the geographical area and have changed in the last decades. We studied the spectrum of dermatophytoses by means of a retrospective analysis involving 6,133 patients referred to the Mycology Service of the Dermatology Clinic of Policlinico Hospital - University of Bari, Italy during the period 2005-2010. The most frequent clinical forms were tinea unguium (39.

CDKN1C/P57 is regulated by the Notch target gene Hes1 and induces senescence in human hepatocellular carcinoma.

CDKN1C/P57 is a cyclin-dependent kinase inhibitor implicated in different human cancers, including hepatocellular carcinoma (HCC); however, little is known regarding the role of CDKN1C/P57 and its regulation in HCC. In this study, we show that the down-regulation of Notch1 and Notch3 in two HCC cell lines resulted in Hes1 down-regulation, CDKN1C/P57 up-regulation, and reduced cell growth. In line with these data, we report that CDKN1C/P57 is a target of transcriptional repression by the Notch effector, Hes1.

The decrease of cell membrane fluidity by the non-steroidal anti-inflammatory drug Licofelone inhibits epidermal growth factor receptor signalling and triggers apoptosis in HCA-7 colon cancer cells.

The ability to induce changes in cell membrane properties is nowadays considered an additional mechanism to explain the pharmacological effects of non-steroidal anti-inflammatory drugs (NSAIDs). We previously demonstrated that the NSAID Licofelone, a dual cyclooxygenase/5-lipoxygenase inhibitor, triggers apoptosis in HCA-7 colon cancer cells independently from the inhibition of these enzymes. Here, we provide evidence that, in HCA-7 cells, the pro-apoptotic effect of this drug relies, at least in part, on its ability to inhibit epidermal growth factor receptor (EGFR) signalling by a decrease of cell membrane fluidity.

In hepatocellular carcinoma miR-519d is up-regulated by p53 and DNA hypomethylation and targets CDKN1A/p21, PTEN, AKT3 and TIMP2.

MiR-519d belongs to the chromosome 19 miRNA cluster (C19MC), the largest human miRNA cluster. One of its members, miR-519d, is over-expressed in hepatocellular carcinoma (HCC) and we characterized its contribution to hepatocarcinogenesis. In HCC cells, the over-expression of miR-519d promotes cell proliferation, invasion and impairs apoptosis following anticancer treatments.
