INTRODUCTION: The best method for assessing renal function after partial nephrectomy (PN) continues to be a matter of debate. Early studies evaluated kidney function by measuring serum creatinine (sCr) and/or the estimated glomerular filtration rate (eGFR), potentially underestimating the contribution of the contralateral kidney in masking alterations in renal function. Since then, researchers have studied the operated renal unit with the aid of nuclear renal scans (RS). However, taking into consideration the importance of the amount of renal parenchyma spared or sacrificed during PN, many novel methods have been proposed for determining kidney volume before and after PN...

Background: Most pituitary neuroendocrine tumors (PitNET) show benign behavior, but a significant number are invasive, recur or resist to medical treatment. Based on a retrospective case-control study we recently proposed a classification of PitNETs of prognostic relevance. This prospective study aims to test the value of this classification in an independent patient cohort. Methods: The cohort included patients of a single center operated upon a PitNET. Using a grading system based on invasion on MRI, immunocytochemical profile (ICC), Ki-67, mitotic index, and p53 positivity, tumors were classified...

Background: EORTC 24971 was a phase III trial demonstrating superiority of induction regimen TPF over PF, in terms of progression-free (PFS) and overall survival (OS) in locoregionally advanced unresectable HNSCC. We conducted a retrospective analysis of prospectively collected data aiming to evaluate whether only HPV(-) patients (pts) benefit from adding docetaxel to PF, in which case de-intensifying induction treatment in HPV(+) pts could be considered. Methods: Pre-therapy tumor biopsies (blocks or slides) were assessed for high-risk HPV by p16 immunohistochemistry, PCR and qPCR...

INTRODUCTION: Hepatoblastoma with tumour thrombi extending into inferior-vena-cava and right atrium are often unresectable with an extremely poor prognosis. The surgical approach is technically challenging and might require major liver resection with vascular reconstruction and extracorporeal circulation. However, which is the best surgical technique is yet unclear. PRESENTATION OF CASE: A 11-months-old boy was referred for a right hepatic lobe mass(90×78mm) suspicious of hepatoblastoma with tumoral thrombi extending into the inferior-vena-cava and the right atrium, bilateral lung lesions and serum alpha-fetoprotein level of 50...

The extraordinary properties of black phosphorus (BP) make it a promising candidate for next-generation transistor chemical sensors. However, BP films reported so far are supported on substrate, and substrate scattering drastically deteriorates its electrical properties. Consequentially, the potential sensing capability of intrinsic BP is highly underestimated and its sensing mechanism is masked. Additionally, the optimum sensing regime of BP remains unexplored. This article is the first demonstration of suspended BP sensor operated in subthreshold regime...

In recent decades, it has become clear that most of human proteins are glycosylated and that protein glycosylation plays an important role in health and diseases. At present, simple, fast and inexpensive methods are sought for clinical applications and particularly for improved diagnostics of various diseases, including cancer. We propose a label- and reagent-free electrochemical method based on chronopotentiometric stripping (CPS) analysis and a hanging mercury drop electrode for the detection of interaction of sialylated protein biomarker a prostate specific antigen (PSA) with two important lectins: Sambucus nigra agglutinin (SNA) and Maackia amurensis agglutinin (MAA)...

PURPOSE: We aimed to compare the immunohistochemical expression of PD-1, PD-L1 and CTLA-4 of pregnancy-related breast cancer (PRBC) and early onset non-PRBC (YWBC), and their prognosis prediction potential was correlated to that of conventional clinicopathological factors. METHODS: Twenty-one PRBC cases were paired with 21 YWBC in this matched case-control study. Immune-checkpoint markers (ICM) were evaluated with immunohistochemistry (IHC) on whole slides using the following antibodies: PD-1 (NAT-105), PD-L1 (28-8) and CTLA-4 (F-8)...

PURPOSE: Although large-scale randomised clinical trials have established that radiotherapy (RT) - alone or combined with hormonal therapy (HT) - is effective in reducing the risk of ipsilateral breast tumour recurrence (IBTR), overall survival does not seem to be improved by adjuvant therapies. We sought to ascertain whether specific criteria can be adopted to avoid RT with an acceptable rate of IBTR after breast-conserving surgery (BCS) achieving tumour-free margins. PATIENTS AND METHODS: This non-randomised prospective study concerned the outcome of patients who underwent BCS for ductal carcinoma in situ (DCIS) and were prospectively assessed by means of an established scoring system based on width of free margins in association with age <40, presence of comedonecrosis, high grade, ER negativity and HER2 positivity, to orient the use of any adjuvant therapies...

Using primary cultures of normal human prostate epithelial cells, we developed a novel prostasphere-based, label-retention assay that permits identification and isolation of stem cells at a single cell level. Their bona fide stem cell nature was corroborated using in vitro and in vivo regenerative assays and documentation of symmetric/asymmetric division. Robust WNT10B and KRT13 levels without E-cadherin or KRT14 staining distinguished individual stem cells from daughter progenitors in spheroids. Following FACS to isolate label-retaining stem cells from label-free progenitors, RNA-seq identified unique gene signatures for the separate populations which may serve as useful biomarkers...

Data on gene transcription profiles provide a comprehensive assessment of the toxic and defensive mechanisms that are triggered by pollutants. PCR-arrays have emerged as a reliable tool for analyzing the expression of a panel of relevant, pathway- or disease-focused genes under uniform cycling conditions. By using SYBR Green-optimized primer assays, it is possible to simultaneously amplify a sample with high specificity and amplification efficiencies. However, commercial PCR-arrays target a limited group of organisms, excluding most of those with environmental relevance, as is the case with Mus spretus mice...

With the demand for fresh produce increases in recent decades, concerns for microbiological safety of fresh produce are also raised. To identify effective ultraviolet (UV) light treatment for fresh produce decontamination, we first determined the effect of three forms of UV treatment, dry UV (samples were treated by UV directly), wet UV (samples were dipped in water briefly and then exposed to UV), and water-assisted UV (samples were treated by UV while being immersed in agitated water) on inactivation of Salmonella inoculated on tomatoes and fresh-cut lettuce...

Monoethanolamine (MEA), a potential atmospheric pollutant from capture unit of a leading CO2 capture technology, could be removed by participating H2SO4-based new particle formation (NPF) as simple amines. Here we evaluated the enhancing potential of MEA on H2SO4-based NPF by examining the formation of molecular clusters of MEA and H2SO4 using a combined quantum chemistry calculations and kinetics modeling. The results indicate that MEA at ppt-level can enhance H2SO4-based NPF. The enhancing potential of MEA is < dimethylamine (DMA), one of the strongest enhancing agents, and ≫ methylamine (MA), in contrast to the order suggested solely by their basicity (MEA < MA < DMA)...
