UnknownLamellar ordering, droplet formation and phase inversion in exotic active emulsions.
We study numerically the behaviour of a two-dimensional mixture of a passive isotropic fluid and an active polar gel, in the presence of a surfactant favouring emulsification. Focussing on parameters for which the underlying free energy favours the lamellar phase in the passive limit, we show that t...

UnknownAssociation between Urinary Levels of Aflatoxin and Consumption of Food Linked to Maize or Cow Milk or Dairy Products.
The aim of this analysis was to assess the association between consumption of maize and dairy products and urine and serum levels of aflatoxin FM1 (AFM1) in a sample of 59 males occupationally exposed (29) and non-exposed (30) to aflatoxins. Two urine samples were collected for each person; each sam...

UnknownMolecular Epidemiology of B3 and D8 Measles Viruses through Hemagglutinin Phylogenetic History.
Of the 24 known measles genotypes, only D8 and B3 are responsible for outbreaks in the last years in Europe, Asia, and America. In this study the H gene of 92 strains circulating between 2015 and 2019 in Lombardy, Northern Italy, and 1273 H sequences available in GenBank were analyzed in order to ev...

UnknownImpact of differentiating between persistent and new infections on colposcopy referral in HPV-positive triage-negative women: results from the NTCC2 study.

Background

In cervical screening, human papillomavirus (HPV)-positive women at 1-year retesting are typically referred to colposcopy. This study, by the use of extended genotyping, estimates the impact of distinguishing persistent from new infections in an effort to reduce colposcopy referra...

TranscriptomicsAssessment of low-dose BPA toxicity in thyroid follicular cells by gene expression microarray.
Gene expression microarrays were performed to investigate the molecular effects of exposure to BPA on thyrocytes (FRTL-5). Cells were treated with low-lose BPA (10^-9 M) at different time points to analyse time dependent toxicity.

UnknownHuman placenta-derived neurospheres are susceptible to transformation after extensive in vitro expansion.

Introduction

The cancer stem cell model links neoplastic cells with normal stem cell biology, but little is known on how normal stem cells are transformed into cancer stem cells.

Methods

To investigate the processes underlying the transformation of normal stem cells we developed in vi...

UnknownDown-regulation of the Lamin A/C in neuroblastoma triggers the expansion of tumor initiating cells.
Tumor-initiating cells constitute a population within a tumor mass that shares properties with normal stem cells and is considered responsible for therapy failure in many cancers. We have previously demonstrated that knockdown of the nuclear envelope component Lamin A/C in human neuroblastoma cells ...

UnknownFirst seroprevalence study of West Nile Virus (WNV) infection in blood donors after the upsurge of West Nile Neuroinvasive Disease (WNND) cases in southern Italy in 2023.

Background

Mosquito-borne diseases are an emerging threat in Europe. West Nile virus (WNV) is an arbovirus commonly transmitted in an enzootic cycle involving ornithophilic mosquitoes as major vectors. In recent years, global climate change has been identified as a significant driver of the ...

UnknownThe Cleavage-Specific Tau 12A12mAb Exerts an Anti-Amyloidogenic Action by Modulating the Endocytic and Bioenergetic Pathways in Alzheimer's Disease Mouse Model.
Beyond deficits in hippocampal-dependent episodic memory, Alzheimer's Disease (AD) features sensory impairment in visual cognition consistent with extensive neuropathology in the retina. 12A12 is a monoclonal cleavage specific antibody (mAb) that in vivo selectively neutralizes the AD-relevant, harm...

UnknownEstrogenicity of chemical mixtures revealed by a panel of bioassays.
Estrogenic compounds are widely released to surface waters and may cause adverse effects to sensitive aquatic species. Three hormones, estrone, 17β-estradiol and 17α-ethinylestradiol, are of particular concern as they are bioactive at very low concentrations. Current analytical methods are not all s...
