Polyoxypregnanes as safe, potent, and specific ABCB1-inhibitory pro-drugs to overcome multidrug resistance in cancer chemotherapy in vitro and in vivo

2021

Multidrug resistance (MDR) mediated by ATP binding cassette subfamily B member 1 (ABCB1) is significantly hindering effective cancer chemotherapy. However, currently, no ABCB1-inhibitory drugs have been approved to treat MDR cancer clinically, mainly due to the inhibitor specificity, toxicity, and drug interactions. Here, we reported that three polyoxypregnanes (POPs) as the most abundant constituents of Marsdenia tenacissima (M. tenacissima) were novel ABCB1-modulatory pro-drugs, which underwent intestinal microbiota-mediated biotransformation in vivo to generate active metabolites. The metabolites at non-toxic concentrations restored chemosensitivity in ABCB1-overexpressing cancer cells v…

Experimental lung injury induces cerebral cytokine mRNA production in pigs

2020

Background Acute respiratory distress syndrome (ARDS) is an important disease with a high incidence among patients admitted to intensive care units. Over the last decades, the survival of critically ill patients has improved; however, cognitive deficits are among the long-term sequelae. We hypothesize that acute lung injury leads to upregulation of cerebral cytokine synthesis. Methods After approval of the institutional and animal care committee, 20 male pigs were randomized to one of three groups: (1) Lung injury by oleic acid injection (OAI), (2) ventilation only (CTR) or (3) untreated. We compared neuronal numbers, proportion of neurons with markers for apoptosis, activation state of Ib…

From Laboratory Mixes Evaluation to Full Scale Test: Fatigue Behavior of Bio-Materials Recycled Asphalt Mixtures

2020

The present paper describes the full-scale accelerated test, carried out on asphalt pavements made up with bio-materials, especially designed to help reusing Reclaimed Asphalt (RA) by re-activating the aged binder. Four pavement sections were evaluated: three pavement sections with innovative bio-materials (bio-recycled asphalt mixtures), and a reference section with a conventional, high modulus asphalt mix (EME2). In this study, fatigue resistance was first evaluated in laboratory, with two-points bending test, and then at full scale under heavy traffic loading, with the IFSTTAR accelerated pavement testing facility. The evolution of bio-materials recycled asphalt mixture characteristics, …

'Opera e declamazione teatrale in Italia nel Diciottesimo secolo. Convergenze e problemi'

2014

The fulfilment of the operatic reform, managed by Christoph Willibald Gluck and his librettist Ranieri Calzabigi in 1760s’ Vienna, is a well-known topic. This event, whose seeds date back to the 1740s, has been examined according to theatrical and literary experiences in France and Italy. However, the question of acting influence on opera can be reconsidered at the light of the latest discovery of symbols collected and labelled as drammatica – metodo italiano. Engraved in some writings, this set of signs is often connected to music and offers the matter for a new critical survey about the discourse on music declamation before and after Calzabigi. From the 1830s onwards the theory of acting …

DO FLEXIBLE AND TENACIOUS GOAL PURSUIT ALLEVIATE THE INFLUENCES OF FUNCTIONAL DECLINE TO ACTIVITY PARTICIPATION?

2018

Assimilative and accommodative coping strategies have hardly been studied in relation to activity participation when facing functional decline. We investigated whether tenacious goal pursuit (TGP) and flexible goal adjustment (FGA) influence the association between physical or cognitive performance, and physical activity or participation in other hobbies. Participants were 78-93-year-old community-dwelling people (n=187). TGP and FGA were self-evaluated with distinct scales (ranges 5–25). Physical performance was assessed with Short Physical Performance Battery (SPPB; 0–12) and cognitive performance with Mini-Mental State Examination (MMSE; 0–30). Physical activity (0–5) and participation i…

The Reform of the Rappresentativa: Roots and Routes of a National Art

2015

Curated Panel: Italian Acting I explore the remarkable role that the reform of the old Rappresentativa played in the years of Risorgimento, and examine the differences of application of the declamatory symbols in the old Rappresentativa and in the New Style that is referred as la romantica, or Drammatica, analysing Gustavo Modena, Adelaide Ristori and Gaetano Gattinelli’s prompt books and works. Gustavo Modena reformed the old style of the Rappresentativa and was an unforgettable patriot of Risorgimento as well as Ristori and Gattinelli. I explain how Modena steered the drammatica along a new course in the first fifty years of the nineteenth century and shaped the method giving it the goal …

Redirected EBV-Specific Stem Cell-Memory and Central-Memory CD8+ T Lymphocytes Exhibit Effective and Sustained Antileukemic Immunity to Acute Myeloid…

2014

Abstract Introduction: Adoptive cellular therapy (ACT) of donor-derived cytolytic T lymphocytes (CTL) directed to leukemia or herpesvirus has proven promising to improve antiviral and antileukemic immunity in patients following allogeneic hematopoietic stem cell transplantation (AHSCT). However, durable clinical responses are often hampered by detrimental graft-versus host (GvH) reactivity and limited persistence of transferred, fully differentiated antileukemic effector T cells (TEFF). We thus explored memory and tumoricidal features of in vitro generated EBV-specific stem cell-memory T cells (TSCM) and central-memory T (TCM) cells, T cell-receptor (TCR) redirected to primary acute myeloid…

Hemostatic Abnormalities in Patients With Severe Preeclampsia

2007

Preeclampsia is the most common medical disorder of pregnancy. Early onset preeclampsia is defined as presentation of hypertension and proteinuria before 34 weeks of gestation. Alterations of endothelial cells and fibrin deposition in microvasculature lead to enhanced activation of the coagulation cascade and impaired fibrinolysis associated with multiple organ dysfunctions. Plasma samples were obtained from 50 patients with severe preeclampsia before 34 weeks of gestation and in 61 patients with late preeclampsia. Factor VIIIR:Ag, fibrinogen, D-dimer, and thrombomodulin increased with advanced pregnancy. The platelet count is very important because of the close correlation with the activa…

An Autistic Endophenotype and Testosterone Are Involved in an Atypical Decline in Selective Attention and Visuospatial Processing in Middle-Aged Women

2015

Mothers of offspring with autism spectrum disorders (ASD) could present mild forms of their children’s cognitive characteristics, resulting from prenatal brain exposure and sensitivity to testosterone (T). Indeed, their cognition is frequently characterized by hyper-systemizing, outperforming in tests that assess cognitive domains such as selective attention, and fine motor and visuospatial skills. In the general population, all these start to decline around the mid-forties. This study aimed to characterize whether middle-aged women who are biological mothers of individuals with ASD had better performance in the aforementioned cognitive skills than mothers of normative children (in both gro…
