Physicians do not routinely recommend smokers to undergo spirometry, unless they are symptomatic.Aims: To investigate the effectiveness of voluntary lung function screening in bringing to light patients with previously unknown COPD and to evaluate the relationships among symptoms, smoking status, and airway obstruction.Methods: A voluntary screening study for COPD was conducted during two editions of the annual Fiera del Levante (2014 and 2015), an international trade fair in Bari. Subjects were eligible for the study if they fulfilled the following inclusion criteria: age ≥35 years, smoker/ex-smoker ≥5 pack-years (PYs), or at least one chronic respiratory symptom (cough, sputum production, shortness of breath, and wheezing). A free post-β2-agonist spirometry test was performed by trained physicians for each participant using portable spirometers. Post-β2-agonist forced expiratory volume in 1 second (FEV1):forced vital capacity ratio

Abstract

We report on an X-ray polarimetric observation of the high-mass X-ray binary LMC X-1 in the high/soft state, obtained by the Imaging X-ray Polarimetry Explorer (IXPE) in 2022 October. The measured polarization is below the minimum detectable polarization of 1.1 per cent (at the 99 per cent confidence level). Simultaneously, the source was observed with the Neutron Star Interior Composition Explorer (NICER), Nuclear Spectroscopic Telescope Array (NuSTAR), and Spectrum-Rontgen-Gamma (SRG)/Astronomical Roentgen Telescope – X-ray Concentrator (ART-XC) instruments, which enabled spectral decomposition into a dominant thermal component and a Comptonized one. The low 2–8 keV polarization of the source did not allow for strong constraints on the black hole spin and inclination of the accretion disc. However, if the orbital inclination of about 36° is assumed, then the upper limit is consistent with predictions for pure thermal emission from geometrically thin and optically thick discs. Assuming the polarization degree of the Comptonization component to be 0, 4, or 10 per cent, and oriented perpendicular to the polarization of the disc emission (in turn assumed to be perpendicular to the large-scale ionization cone orientation detected in the optical band), an upper limit to the polarization of the disc emission of 1.0, 0.9, or 0.9 per cent, respectively, is found (at the 99 per cent confidence level).

Abstract

Acrolein is the simplest unsaturated aldehyde widely used in chemical industry. It is an important chemical intermediate with a high degree of reactivity arising from the conjugation of the vinyl with a carbonyl group. In the chemical industry, acrolein can be converted to high quantity of different derivatives, such as acrylic acid, methionine, biocides and other high added-values products. Today, acrolein is industrially produced by propylene oxidation. However, the need to reduce greenhouse gas emissions drives the search for more sustainable methods of production starting from biomaterials [1]. In this respect, oxidative coupling of biosourced alcohols has emerged as a viable alternative to potentially replace fossil fuel-based production from propylene. This gas-phase process allows the production of acrolein in a single reactor, minimizing the investment costs [2].Even if this process can be performed in a single reactor with iron molybdate (FeMoOx) as a reference redox catalyst, the process is constituted of two steps. The first step implies the oxidation of a mixture of bio-methanol and –ethanol to produce formaldehyde and acetaldehyde, then the second step concerns aldol-condensation of the aldehydes and followed by a dehydration to acrolein in presence of oxygen. Knowing that aldolisation reactions are generally catalyzed by basic and/or acidic sites, improved yield and selectivity towards acrolein should be obtained by enhancing the cross-aldolization reaction on acid/base catalysts [3-4].Spinel catalysts (supplied by Baikowski) where magnesium was partly or totally substituted by transition metals. The acidic and basic properties of the catalysts were determined by adsorption microcalorimetry of NH3 and SO2 probe molecules. The experiments were performed at 150 °C in a Tian-Calvet heat flow calorimeter (C80 from Setaram) linked to a volumetric apparatus equipped with a Barocel capacitance manometer for pressure measurements. This equipment gives access to the number, strength and strength distribution of the adsorption sites. In order to obtain more information about adsorption of the reactants, microcalorimetry experiments were also performed with formaldehyde and acetaldehyde following the same protocol as for NH3 and SO2 but at a lower temperature (30°C). Catalytic reactions were performed in two sequential reactors, the first one containing FeMoOx catalysts while the second one was filled with spinel catalysts. The reaction was performed between at285 °C in presence of oxygen with Gas Hourly Space Velocity (GHSV) varying from 5000 to 10000 h-1Figure 1 displays the list of the various studied spinels and the acrolein production versus the ionic radius of transition metals substituting magnesium. Among spinel catalysts, the best results were exhibited by (0.8Mg 0.2Mn) Al2O4 with 31 % yield and 40 % selectivity at 285°C and 5000 h-1.It can be observed that acrolein production clearly depends on the cationic species, increasing with ionic radius. In addition to these results, consecutive adsorptions of acetaldehyde and formaldehyde were also studied by adsorption microcalorimetry to further investigate the mechanism of adsorption. The results allowed us to explain the absence of crotonaldehyde (product of self aldolization of acetaldehyde) and the prevalence of acrolein in the final products, which are both due to the isolation of acetaldehyde by formaldehyde at the surface of the catalyst

Abstract

The study of radiation emitted from black hole (BH) accretion discs represents a crucial way to understand the main physical properties of these sources, and in particular the BH spin. Beside spectral analysis, polarimetry is becoming more and more important, motivated by the development of new techniques which will soon allow to perform measurements also in the X- and γ-rays. Photons emitted from BH accretion discs in the soft state are indeed expected to be polarized, with an energy dependence which can provide an estimate of the BH spin. Calculations performed so far, however, considered scattering as the only process to determine the polarization state of the emitted radiation, implicitly assuming that the temperatures involved are such that material in the disc is entirely ionized. In this work, we generalize the problem by calculating the ionization structure of a surface layer of the disc with the public code cloudy , and then by determining the polarization properties of the emerging radiation using the Monte Carlo code stokes. This allows us to account for absorption effects alongside scattering ones. We show that including absorption can deeply modify the polarization properties of the emerging radiation with respect to what is obtained in the pure-scattering limit. As a general rule, we find that the polarization degree is larger when absorption is more important, which occurs, for example, for low accretion rates and/or spins when the ionization of the matter in the innermost accretion disc regions is far from complete.

Abstract

The chemokine receptor CXCR4 and CD133, putative stem cell markers, were previously described in renal cancer (RCC). To evaluate the biological and prognostic role of CD133 and CXCR4 in RCC the expression was evaluated through qPCR and immunoblotting in human renal cancer cell lines (786-O, A498, ACHN, CAKI-1, SN12C, TK10, UO31) and patients biopsies. Renal cancer cells and surgical biopsies expressed functional CXCR4 while CD133 was not detectable. CXCR4 and CD133 expression was then evaluated in 240 renal cancer patients through immunohistochemistry. CXCR4 and CD133 were low in 19.1% and 59.6%; intermediate in 20% and 17.9%; high in 60.8% and 22.5% of the cases, respectively. CXCR4 was overexpressed in tumours (p= 0.02), while CD133 was over expressed in healthy tissues (p= 0.04). Disease free survival Kaplan Meier plots suggest that prognosis is unfavourable for patients whose primary tumours express CXCR4 (p= 0.0199) but nor CD133 (p= 0.151) neither the concomitant CXCR4-CD133 (p=0.848) high expression affected prognosis. Analysis of prognostic factors suggests that age, clinical presentation, AJCC stage and CXCR4 had a significant prognostic value at the univariate analysis. The CXCR4 predictive ability was confirmed at the multivariate analysis while no prognostic role was identified for CD133.Thus concomitant CD133 and CXCR4 evaluation is not worth in RCC patient while the CXCR4 prognostic role encourage CXCR4 antagonists as promising therapeutic option.

Abstract

Chemical-physical properties, colour parame ters, antioxidant activities (AA), carotenoid and polyphenol levels (CL) in seven cultivars of yellow flesh peaches , five cultivars of yellow flesh nectarines and one cultivar of white flesh nectarines at harvest time and after 7 days of cold storage were evaluated. Peaches had major variability in flesh firmness (FF) and titratable acidity (TA) and lower soluble solid concentration (SSC) than nectarines . Evaluation of ground colour parameters, a*, b* and L*, showed that nectarines had a yellow-orange hue with high lightness, while peaches were darker, tending to red-green . Hydrophilic, lipophilic antioxidant activities of extracts (W-AA and L-AA), carotenoids and polyphenols levels (CL and PL) were evaluated and their relation with commercial maturation. The average of W-AA at harvest time was 11.0 TEAC, while the L-AA values at harvest time was on average higher in peaches (2.0 TEAC) than in nectarines (1.3 TEAC). 'The yellow flesh had higher amounts of total carotenoids (182.45 ug/l00 g fw for peaches and 117.37 ug/100 g fw for yellow flesh nectarines). During cold storage, W-AA increased for nectarines (+22.9% in yellow flesh and +19.2% in white flesh) and peaches as well as polyphenolic compounds (+13.37%) while, contents of carotenoids decreased (-8.7%).

Abstract

A Rh-based catalyst for low temperature hydrogen generation in membrane microreactor applications has been developed and characterized. A RhZrO2 catalyst with 1.4 wt% Rh was prepared by incipient wetness impregnation and was tested for both methane reforming and autothermal reforming at temperatures interesting for membrane reactor applications (i.e. temperatures below 700 °C and steam-to-carbon ratio of 2). The kinetic parameters to describe the reaction rate of both methane steam reforming (SMR) and auto-thermal reforming (ATR) over the RhZrO2 catalyst have been determined using a 1D heterogeneous packed bed reactor model to properly account for mass and heat transfer resistances.

Abstract

Non-Muscle-Invasive-Bladder-Cancer represents 75-85% of the new bladder cancer cases per year. Trans-uretral vesical resection is the milestone for diagnosis and therapy. After primary treatment, recurrence is frequent depending on the presence of several established risk factors: multiplicity, T dimension, prior recurrence. In some patients disease progress to an advanced stage. Adjuvant chemo-immunotherapy has been widely used depending on the risk category assigned on the basis of the risk factors for recurrence. In low risk categories a one shot treatment with chemotherapy is considered the standard treatment without any maintenance therapy. In intermediate risk patients, adjuvant induction therapy and maintenance chemotherapy or immunotherapy for at least one year is recommended. In high risk patients adjuvant induction and maintenance immunotherapy until 3 years is considered the best strategy. In this review data on the different drugs used in this setting will be discussed. [ABSTRACT FROM AUTHOR]

Abstract

In this work, wave formation in laser-produced plasma is investigated by an analysis of time-of-flight signal of the electron pulse. Electrons are extracted from a non-equilibrium plasma, generated by pulsed laser ablation on a solid Ge target. The process is represented by ion-acoustic waves, which are generated from an external perturbation, given by the positive bias voltage of a Faraday cup. The characteristics of the waves depend substantially on the geometry of the plasma expansion chamber and on laser fluence, but are independent on bias potential. A KrF excimer UV laser was employed for plasma generation. Measurements were performed at two different laser fluences, 4 and 7 J/cm 2 . The plasma created propagates with a mean velocity of about 1.1?×?10 4 m/s. A movable Faraday cup was employed in order to collect electrons at different bias voltage values. [ABSTRACT FROM AUTHOR]

Abstract

Soft tissue tumors are a heterogeneous group of tumors, traditionally classified according to morphology and histogenesis. Molecular classification divides sarcomas into two main categories: (a) sarcomas with specific genetic alterations and (b) sarcomas showing multiple complex karyotypic abnormalities without any specific pattern. Most chromosomal alterations are represented by translocations which are increasingly detected. The identification of fusion transcripts, in fact, not only support the diagnosis but also provides the basis for the development of new therapeutic strategies aimed at blocking aberrant activity of the chimeric proteins. One of the genes most susceptible to breakage/translocation in soft tissue tumors is represented by Ewing sarcoma breakpoint region 1 (EWSR1). This gene has a large number of fusion partners, mainly associated with the pathogenesis of Ewing's sarcoma but with other soft tissue tumors too. In this review, we illustrate the characteristics of this gene/protein, both in normal cellular physiology and in carcinogenesis. We describe the different fusion partners of EWSR1, the molecular pathways in which is involved and the main molecular biology techniques for the identification of fusion transcripts and for their inhibition.

Abstract

Introduction A hypercoagulable condition was described in patients with coronavirus disease 2019 (COVID-19) and proposed as a possible pathogenic mechanism contributing to disease progression and lethality. Aim We evaluated if in-hospital administration of heparin improved survival in a large cohort of Italian COVID-19 patients. Methods In a retrospective observational study, 2,574 unselected patients hospitalized in 30 clinical centers in Italy from February 19, 2020 to June 5, 2020 with laboratory-confirmed severe acute respiratory syndrome coronavirus-2 infection were analyzed. The primary endpoint in a time-to event analysis was in-hospital death, comparing patients who received heparin (low-molecular-weight heparin [LMWH] or unfractionated heparin [UFH]) with patients who did not. We used multivariable Cox proportional-hazards regression models with inverse probability for treatment weighting by propensity scores. Results Out of 2,574 COVID-19 patients, 70.1% received heparin. LMWH was largely the most used formulation (99.5%). Death rates for patients receiving heparin or not were 7.4 and 14.0 per 1,000 person-days, respectively. After adjustment for propensity scores, we found a 40% lower risk of death in patients receiving heparin (hazard ratio = 0.60; 95% confidence interval: 0.49–0.74; E-value = 2.04). This association was particularly evident in patients with a higher severity of disease or strong coagulation activation. Conclusion In-hospital heparin treatment was associated with a lower mortality, particularly in severely ill COVID-19 patients and in those with strong coagulation activation. The results from randomized clinical trials are eagerly awaited to provide clear-cut recommendations.

Abstract

The efficacy of hydroxychloroquine (HCQ) in treating SARS-CoV-2 infection is harshly debated, with observational and experimental studies reporting contrasting results. To clarify the role of HCQ in Covid-19 patients, we carried out a retrospective observational study of 4,396 unselected patients hospitalized for Covid-19 in Italy (February–May 2020). Patients’ characteristics were collected at entry, including age, sex, obesity, smoking status, blood parameters, history of diabetes, cancer, cardiovascular and chronic pulmonary diseases, and medications in use. These were used to identify subtypes of patients with similar characteristics through hierarchical clustering based on Gower distance. Using multivariable Cox regressions, these clusters were then tested for association with mortality and modification of effect by treatment with HCQ. We identified two clusters, one of 3,913 younger patients with lower circulating inflammation levels and better renal function, and one of 483 generally older and more comorbid subjects, more prevalently men and smokers. The latter group was at increased death risk adjusted by HCQ (HR[CI95%] = 3.80[3.08-4.67]), while HCQ showed an independent inverse association (0.51[0.43-0.61]), as well as a significant influence of cluster∗HCQ interaction ( p < 0.001 ). This was driven by a differential association of HCQ with mortality between the high (0.89[0.65-1.22]) and the low risk cluster (0.46[0.39-0.54]). These effects survived adjustments for additional medications in use and were concordant with associations with disease severity and outcome. These findings suggest a particularly beneficial effect of HCQ within low risk Covid-19 patients and may contribute to clarifying the current controversy on HCQ efficacy in Covid-19 treatment.

Abstract

Background: Protease inhibitors have been considered as possible therapeutic agents for COVID-19 patients.Objectives: To describe the association between lopinavir/ritonavir (LPV/r) or darunavir/cobicistat (DRV/c) use and in-hospital mortality in COVID-19 patients.Study Design: Multicenter observational study of COVID-19 patients admitted in 33 Italian hospitals. Medications, preexisting conditions, clinical measures, and outcomes were extracted from medical records. Patients were retrospectively divided in three groups, according to use of LPV/r, DRV/c or none of them. Primary outcome in a time-to event analysis was death. We used Cox proportional-hazards models with inverse probability of treatment weighting by multinomial propensity scores.Results: Out of 3,451 patients, 33.3% LPV/r and 13.9% received DRV/c. Patients receiving LPV/r or DRV/c were more likely younger, men, had higher C-reactive protein levels while less likely had hypertension, cardiovascular, pulmonary or kidney disease. After adjustment for propensity scores, LPV/r use was not associated with mortality (HR = 0.94, 95% CI 0.78 to 1.13), whereas treatment with DRV/c was associated with a higher death risk (HR = 1.89, 1.53 to 2.34, E-value = 2.43). This increased risk was more marked in women, in elderly, in patients with higher severity of COVID-19 and in patients receiving other COVID-19 drugs.Conclusions: In a large cohort of Italian patients hospitalized for COVID-19 in a real-life setting, the use of LPV/r treatment did not change death rate, while DRV/c was associated with increased mortality. Within the limits of an observational study, these data do not support the use of LPV/r or DRV/c in COVID-19 patients.

Abstract

Objective The hypothesis that been set forward that use of Renin Angiotensin Aldosterone System (RAAS) inhibitors is associated with COVID−19 severity. We set-up a multicenter Italian collaboration (CORIST Project, ClinicalTrials.gov ID: NCT04318418 ) to retrospectively investigate the relationship between RAAS inhibitors and COVID−19 in-hospital mortality. We also carried out an updated meta-analysis on the relevant studies. Methods We analyzed 4069 unselected patients with laboratory-confirmed SARS-CoV-2 infection and hospitalized in 34 clinical centers in Italy from February 19, 2020 to May 23, 2020. The primary end-point in a time-to event analysis was in-hospital death, comparing patients who received angiotensin-converting–enzyme inhibitors (ACE I) or angiotensin-receptor blockers (ARB) with patients who did not. Articles for the meta-analysis were retrieved until July 13th, 2020 by searching in web-based libraries, and data were combined using the general variance-based method. Results Out of 4069 COVID−19 patients, 13.5% and 13.3% received ACE-I or ARB, respectively. Use of neither ACE-I nor ARB was associated with mortality (multivariable hazard ratio (HR) adjusted also for COVID−19 treatments: 0.96, 95% confidence interval 0.77–1.20 and HR = 0.89, 0.67–1.19 for ACE-I and ARB, respectively). Findings were similar restricting the analysis to hypertensive (N = 2057) patients (HR = 1.00, 0.78–1.26 and HR = 0.88, 0.65–1.20) or when ACE-I or ARB were considered as a single group. Results from the meta-analysis (19 studies, 29,057 COVID−19 adult patients, 9700 with hypertension) confirmed the absence of association. Conclusions In this observational study and meta-analysis of the literature, ACE-I or ARB use was not associated with severity or in-hospital mortality in COVID−19 patients.

Abstract

GPR30 is a 7-transmembrane G protein-coupled estrogen receptor that functions alongside traditional estrogen receptors to regulate cellular responses to 17?-estradiol and environmental estrogens. In this study, we have evaluated by immunohistochemical analysis GPR30 expression in post-puberal testicular germ cell tumors (30 seminomas, 5 teratomas, 12 embryonal carcinomas and 20 intratubular germ cell tumors). The GPR30 protein expression was detected at high level in all intratubular germ cell tumors, seminomas and embryonal carcinomas, whereas in teratomas the expression was low. The immunohistochemical data were further confirmed by western blot analysis. GPR30 protein expression has also been analyzed in GC1 and TCam-2 cell lines, respectively derived from immortalized type B murine spermatogonia and human seminoma. Our results indicate that GPR30 could be a potential therapeutic target; the design of a specific GPR30 inhibitors could be a useful molecular target to block neoplastic germ cells with a high proliferative rate for the treatment of TGCTs. © 2011 Landes Bioscience.

Abstract

Epidemiologic studies have clearly demonstrated the correlation existing between Vitamin D (Vit. D) deficiency and increased risk of developing cardiovascular disease, suggesting that it might have a protective role in this clinical setting. Although many experimental studies have investigated the molecular mechanisms by which Vit. D might exert these effects, its potential role in protecting against athero-thrombosis is still partially unknown. We have investigated whether Vit. D might exert anti athero-thombotic effects by preventing expression of adhesion molecules (CAMs) and Tissue Factor (TF), molecules involved in atherothrombotic pathophysiology, in oxLDL stimulated endothelial cells (HUVEC). Moreover, we have investigated whether Vit. D effects might be due to the NF-kB modulation. HUVEC cultivated in medium enriched with Vit. D (10 nM) were stimulated with oxLDL (50 μg/ml). TF gene (RT-PCR), protein (Western blot), surface expression (FACS) and procoagulant activity (FXa generation assay) were measured. Similarly, CAMs gene (RT-PCR), surface expression (FACS) and soluble values (ELISA) were measured. NF-kB translocation was also investigated. Vit. D significantly reduced TF gene as well protein expression and procoagulant activity in oxLDL-treated HUVEC. Similar effects were observed for CAMs. These effects were associated with Vit. D modulation of NF-κB pathway. This study, although in vitro, indicate that Vit. D has protective effect on endothelial cells by inhibiting expression of TF and CAMs, proteins involved in atherothrombotic pathophysiology. Further studies will be necessary to translate these findings to a clinical scenario to better define the potential therapeutical role of Vit. D supplementation in the management of cardiovascular disease in patients with Vit. D deficiency.

Abstract

The epithelial-mesenchymal transition (EMT) plays a key role in tumor progression, drug resistance and metastasis. Recently, numerous microRNA (miRNA) have been described to regulate EMT in tumor progression. In this study, we found that conditioned medium from the LC212 non-small-cell lung cancer (NSCLC) cell line (LC212-CM) induces morphological changes and overexpression of Vimentin, CD90, SMAD 2/3, SLUG and TWIST in A549 NSCLC cells, consistent with a mesenchymal phenotype. To identify the soluble mediators in LC212-CM involved in this phenomenon, we performed miRNA profiling and TGF-β1 quantification. We found that LC212-CM contains high levels of TGF-β1 as well as different secreted miRNAs. We focused our attention on Homo sapiens-microRNA21 (hsa-miR21), one of most relevant miRNA associated with lung cancer progression, metastasis and EMT. An hsa-miR21 antagomiR was able to prevent the LC212-CM-induced EMT phenotype in A549 cells. Furthermore, we found that TGF-β1 and hsa-miR21 cooperate in the induction of EMT in A549 cells. Intriguingly, TGF-β1 was found to induce hsa-miR21 expression in A549 cell, thus suggesting that the hsa-miR21 mediates at least in part the pro-EMT effects of TGF-β1. In conclusion, hsa-miR21 and TGF-β1 are involved in autocrine and paracrine circuits that regulate the EMT status of lung cancer cells.

Abstract

We describe a case of acute myeloid leukemia M5 showing a balanced t(2;10)(q31;p12) translocation. This has never been described before as the sole cytogenetic abnormality in a bone marrow cell clone at onset. Using fluorescence in situ hybridization with properly designed bacterial artificial chromosome probes, we mapped the breakpoint regions on both derivative chromosomes 2 and 10:der(2) and der(10), respectively. The MPP7 gene, disrupted by the breakpoint on chromosome 10, was juxtaposed upstream of both HNRNA3 and NFE2L2 genes on chromosome 2, without the formation of any fusion gene. Using real-time quantitative polymerase chain reaction, we tested the possible disregulation of any of the breakpoint-associated genes as a consequence of the translocation, but we found no statistically significant alteration. Considering the potential role of this clonal cytogenetic abnormality in leukemogenesis, we speculate that this translocation could have an impact on additional genes mapping outside the breakpoint regions. However, the limited amount of RNA material available prevented us from testing this hypothesis in this present case.

Abstract

Urotensin II (UT-II) is a potent vasoconstrictor peptide and its receptor (UTR) was correlated with human cortico-adrenal carcinoma proliferation. In this study, we have evaluated the correlation between UTR expression and prognosis of human prostate adenocarcinoma and the involvement of this receptor in the regulation of biological properties on both in vivo and in vitro models. UTR mRNA and protein, evaluated by real-time PCR and Western blotting, respectively, were expressed at high levels only in androgen-dependent LNCaP cells. In order to investigate UTR changes occurring in human prostate tumorigenesis, we have also evaluated the expression of UTR in vivo in 195 human prostate tissue samples. UTR was always expressed at low intensity in hyperplastic tissues and at high intensity in well-differentiated carcinomas (Gleason 2-3). Moreover, we have evaluated the effects of an antagonist of UTR, urantide on migration and invasion of LNCaP cells. Urantide induced a dose-dependent decrease of motility and invasion of LNCaP cells whose characteristic ameboid movement seems to be advantageous for their malignancy. These effects were paralleled by down-regulating the autophosphorylation of focal adhesion kinase and the integrin surface expression on LNCaP cells. The effects on cell motility and invasion were likely due to the inhibition of RhoA activity induced by both urantide and shRNA UTR. These data suggest that UTR can be considered a prognostic marker in human prostate adenocarcinoma patients.

Abstract

BACKGROUND: Docetaxel (DTX) and zoledronic acid (ZOL) are effective in patients with hormone resistant prostate cancer (HRPC) with bone metastases. A phase I clinical trial of metronomic administration of Zoledronic Acid AN d TaxoterE combination (ZANTE trial) in 2 different sequences was conducted in HRPC. RESULTS: The maximum tolerated dose was not achieved with sequence A. Two patients at third level of sequence B developed dose limiting toxicity. A disease control was obtained in six out of nine patients treated with sequence A, where a decrease of biological markers and PSA were also observed. No evidence of anti-tumor activity was observed in patients treated with sequence B. PATIENTS AND METHODS: Twenty-two patients enrolled into the study (median age: 73 years; range: 43-80) received one of three escalated doses of DTX (30, 40 and 50 mg/m(2)) in combination with a fixed dose of ZOL (2 mg), both administered every 14 days in two different sequences: DTX at the day 1 followed by ZOL at the day 2 (sequence A) or the reverse (sequence B). Patients were evaluated for adverse events and serum IL-8, MMP-2 and MMP-9 were evaluated prior and after therapy with the two sequences of administration of DTX and ZOL. CONCLUSIONS: The bi-weekly combination of DTX (50 mg/m(2)) followed by ZOL was feasible and show promising anti-tumor activity.

Abstract

Background and Objectives We report our initial experience with a relatively new technique, the so-called “dynamic sentinel node biopsy”, in patients with penile cancer. Methods From January 2001 to February 2003, 17 consecutive patients with bilateral, clinically node negative penile cancer were enrolled. Dynamic sentinel node biopsy was followed by local excision of the primary lesion or penile amputation during the same session. Standard inguinal node dissection was performed 4 weeks after the first operation in all the patients. Results Pre-operative lymphoscintigraphy revealed no sentinel nodes in 1, unilateral sentinel nodes in 5, and bilateral in 11 patients. Metastases were noted in 5 out of 16 patients (31.25%), bilaterally in 3 of them. Among the five patients with sentinel node metastasis, this was the only tumor positive lymph node in one patient. In all cases with negative dynamic sentinel node biopsy, no metastatic nodes were found at the following inguinal node dissection. Therefore, the technique showed a 100% negative predictive value and an 88% sensitivity. Conclusions We believe that dynamic sentinel node biopsy is a minimally invasive procedure that can be easily performed. The goal is to offer the possibility of less extensive surgery for selected low risk patients. J. Surg. Oncol. 2006;93: 181–185. © 2006 Wiley-Liss, Inc.

Abstract

Complex non-local behavior makes designing high efficiency and multifunctional metasurfaces a significant challenge. While using libraries of meta-atoms provide a simple and fast implementation methodology, pillar to pillar interaction often imposes performance limitations. On the other extreme, inverse design based on topology optimization leverages non-local coupling to achieve high efficiency, but leads to complex and difficult to fabricate structures. In this paper, we demonstrate numerically and experimentally a shape optimization method that enables high efficiency metasurfaces while providing direct control of the structure complexity through a Fourier decomposition of the surface gradient. The proposed method provides a path towards manufacturability of inverse-designed high efficiency metasurfaces., (© 2024. The Author(s).)
