‘Childish’ beyond Age

2020

This chapter explores the concept of ‘aesthetic sublation’ – a performative mode of meaning making that seeks to degrade its object (; ). Here, the phenomenon of aesthetic sublation is discussed as a form of resistance. Moreover, it is related to intergenerational negotiations through cases in which the labels of ‘childish’ and ‘horrific’ or ‘nasty’ converge. The chapter offers a review of how resistance is conceptualized in, for example, childhood studies, aesthetics and research on popular culture and it asks what can be gained by reconceptualising these instances as aesthetic sublation. peerReviewed

Inappropriateness in laboratory medicine: an elephant in the room?

2017

Appropriateness of diagnostic testing can be conventionally described as prescription of the right test, using the right method, at the right time, to the right patient, with the right costs and for producing the right outcome. There is ongoing debate about the real burden of inappropriateness in laboratory diagnostics. The media coverage of this issue has also recently led to either over- or under-emphasizing the clinical, organizational and economic consequences. This is quite problematic, inasmuch as some reliable data are available in the current scientific literature, showing that inappropriateness of laboratory testing can be as high as 70%. This is especially evident for, though not …

Who's Got the Power? : Young Children's Power and Agency in the Child-Parent Relationship

2015

Children’s rights and their increasing voice in families have made relations between parents and children more democratic. Despite this, child-parent relationships have been claimed to be relationships between unequals from the perspective of power. Often, power is understood as top-down with parents as wielders of power over their children and children as recipients of parental demands. The generational ordering of relations between children and adults poses the challenge of how to conceptualize power in the child-parent relationship, and how methodologically to study power and children’s agency, in particular, from the viewpoint of young children. This study explored in what ways power an…

Sequestrati dalla vendetta: “rimanere chiusi fuori dall’oggetto”

2013

RiassuntoA partire dal loro lavoro di psicoterapeute e attraverso alcuni frammenti clinici che si riferiscono ad un gruppo di adolescenti svoltosi in un quartiere a rischio di Palermo, le Autrici analizzano la dimensione mafiosa non restringendola al solo comportamento criminale; piuttosto declinandola lungo alcuni significanti: non identità e gruppo mafioso che colonizza e sottomette lo psichismo del singolo; fantasmi familiari potenti e spietati che impediscono il costituirsi di sé originali e autonomi; personalità impastate di indifferenza emotiva e vendicatività. Significanti che rendono conto delle vaste aree di desertificazione e pietrificazione – resistenza al cambiamento – avvertita…

Evolution of melanoma cross-resistance to CD8⁺ T cells and MAPK inhibition in the course of BRAFi treatment

2018

The profound but frequently transient clinical responses to BRAFV600 inhibitor (BRAFi) treatment in melanoma emphasize the need for combinatorial therapies. Multiple clinical trials combining BRAFi and immunotherapy are under way to further enhance therapeutic responses. However, to which extent BRAFV600 inhibition may affect melanoma immunogenicity over time remains largely unknown. To support the development of an optimal treatment protocol, we studied the impact of prolonged BRAFi exposure on the recognition of melanoma cells by T cells in different patient models. We demonstrate that autologous CD8+ tumor-infiltrating lymphocytes (TILs) efficiently recognized short-term (3, 7 days) BRAF…

Molecular epidemiology of HIV-1 subtype B in the Basque Country (Spain)

2012

The goal of this work was to study the HIV-1 subtype B epidemic in the Basque Country (Spain). For this, we used HIV samples submitted for genotypic testing of anti-retroviral resistance mutations from 2005 until 2008. Consequently, 2115 HIV-1 sequences comprising protease and retrotranscriptase (PR/RT) coding regions were analyzed. HIV transmission groups were identified by phylogenetic analysis. The 10 largest such groups were subsequently subjected to Bayesian phylogenetic and coalescent reconstructions, using a relaxed molecular clock model. The results obtained show that these groups have been long-standing: most of them were originated in the late 70s or early 80s, and none after the …

EGF-Induced Acetylation of Heterogeneous Nuclear Ribonucleoproteins Is Dependent on KRAS Mutational Status in Colorectal Cancer Cells.

2015

KRAS mutational status is considered a negative predictive marker of the response to anti-EGFR therapies in colorectal cancer (CRC) patients. However, conflicting data exist regarding the variable response to EGFR-targeted therapy. The effects of oncogenic KRAS on downstream targets were studied in cell lines with different KRAS mutations. Cells harboring a single KRASG13D allele showed the most tumorigenic profile, with constitutive activation of the downstream pathway, rendering them EGF-unresponsive. Conversely, KRASA146T cells showed a full EGF-response in terms of signal transduction pathways, cell proliferation, migration or adhesion. Moreover, the global acetylome of CRC cells was al…

Relationship Between Oxidative Stress, ER Stress, and Inflammation in Type 2 Diabetes: The Battle Continues

2019

Type 2 diabetes (T2D) is a metabolic disorder characterized by hyperglycemia and insulin resistance in which oxidative stress is thought to be a primary cause. Considering that mitochondria are the main source of ROS, we have set out to provide a general overview on how oxidative stress is generated and related to T2D. Enhanced generation of reactive oxygen species (ROS) and oxidative stress occurs in mitochondria as a consequence of an overload of glucose and oxidative phosphorylation. Endoplasmic reticulum (ER) stress plays an important role in oxidative stress, as it is also a source of ROS. The tight interconnection between both organelles through mitochondrial-associated membranes (MAM…

In Vitro Modulation of P-Glycoprotein Activity by Euphorbia intisy Essential Oil on Acute Myeloid Leukemia Cell Line HL-60R

2021

Euphorbia species have a large spectrum of traditional medicinal uses. We tested the biological activities of the essential oil (EO) of Euphorbia intisy Drake in an acquired multidrug resistance leukemia model to assess whether the EO obtained by hydrodistillation of stems was able to reverse the resistant phenotype. HL-60R cell lines are characterized by the overexpression of P-glycoprotein (P-gp), inhibitors of apoptosis proteins (IAPs) and constitutive expression of NF-κB. EO chemical composition was determined by GC/MS analysis
