Current driven insulator-to-metal transition without Mott breakdown in Ca$_2$RuO$_4$
2023
The electrical control of a material's conductivity is at the heart of modern electronics. Conventionally, this control is achieved by tuning the density of mobile charge carriers. A completely different approach is possible in Mott insulators such as Ca$_2$RuO$_4$, where an insulator-to-metal transition (IMT) can be induced by a weak electric field or current. This phenomenon has numerous potential applications in, e.g., neuromorphic computing. While the driving force of the IMT is poorly understood, it has been thought to be a breakdown of the Mott state. Using in operando angle-resolved photoemission spectroscopy, we show that this is not the case: The current-driven conductive phase ari…
Human malignant mesothelioma is recapitulated in immunocompetent BALB/c mice injected with murine AB cells
2016
Malignant Mesothelioma is a highly aggressive cancer, which is difficult to diagnose and treat. Here we describe the molecular, cellular and morphological characterization of a syngeneic system consisting of murine AB1, AB12 and AB22 mesothelioma cells injected in immunocompetent BALB/c mice, which allows the study of the interplay of tumor cells with the immune system. Murine mesothelioma cells, like human ones, respond to exogenous High Mobility Group Box 1 protein, a Damage-Associated Molecular Pattern that acts as a chemoattractant for leukocytes and as a proinflammatory mediator. The tumors derived from AB cells are morphologically and histologically similar to human MM tumors, and res…
Proximity Effects on the Charge Density Wave Order and Superconductivity in Single-Layer NbSe2
2021
Collective electronic states such as the charge density wave (CDW) order and superconductivity (SC) respond sensitively to external perturbations. Such sensitivity is dramatically enhanced in two dimensions (2D), where 2D materials hosting such electronic states are largely exposed to the environment. In this regard, the ineludible presence of supporting substrates triggers various proximity effects on 2D materials that may ultimately compromise the stability and properties of the electronic ground state. In this work, we investigate the impact of proximity effects on the CDW and superconducting states in single-layer (SL) NbSe2 on four substrates of diverse nature, namely, bilayer graphene…
Potential Effect of Antiplatelet and Anticoagulant Therapy on the Timing of the Diagnosis of Bladder Cancer
2016
Abstract Background The most common presenting symptom of bladder cancer (BCa) is hematuria. The present study was designed to define whether patients taking antiplatelet and/or anticoagulant drugs might experience hematuria at an earlier stage or grade of BCa. Patients and Methods The data from 1532 consecutive patients who presented to the emergency unit of our institute from 2004 to 2012 because of gross hematuria as a single symptom were evaluated. Patients (n = 227) with a further diagnosis of BCa were included in our study. For the purpose of the present study, patients were divided into 2 groups: patients receiving antiplatelet or anticoagulant therapy (AAT) (group 1) and patients no…
The Impact of Perioperative Blood Transfusion on Survival of Bladder Cancer Patients Submitted to Radical Cystectomy: Role of Anemia Status.
2016
Background The prognostic role of perioperative blood transfusion (PBT) in patients who underwent radical cystectomy (RC) for bladder cancer (BCa), although supported by clinical evidence, still remains to be assessed definitively. Objective To investigate the impact of PBT on RC patients for overall survival and after stratifying according to preoperative anemia status and to define whether the oncologic impact may be assumed to be a primary effect of PBT or attributed to the reduced preoperative hemoglobin (Hb) level. Design, setting, and participants A total of 1490 consecutive patients with nonmetastatic BCa who underwent RC and pelvic lymph node dissection between January 1990 and Augu…
Cancer cell–autonomous contribution of type I interferon signaling to the efficacy of chemotherapy
2014
International audience; The immune system is routinely confronted with cell death resulting from the physiological turnover of renewable tissues, as well as from pathological insults of several types. We hypothesize the existence of a mechanism that allows the immune system to discriminate between physiological and pathological instances of cell death, but the factors that determine whether cellular demise is perceived as a neutral, tolerogenic or immunogenic event remain unclear 1. Infectious insults are accompanied by so-called microbe-associated molecular patterns (MAMPs), i.e., viral or bacterial products that activate immune cells through a panel of pattern-recognition receptors (PRRs)…
