Contribution of narrow band imaging in delineation of laryngopharyngeal superficial cancer spread: a prospective study.

Purpose: The aim of this study was to assess the performance of Narrow Band Imaging (NBI) added to White Light (WL) in the delineation of laryngopharyngeal superficial cancer spread during office-based transnasal flexible endoscopy.

Methods: This bi-centric prospective study was conducted between October 2014 and December 2017. We included consecutive patients with laryngopharyngeal malignant tumors.

Evolution without standing genetic variation: change in transgenerational plastic response under persistent predation pressure.

Transgenerational phenotypic plasticity is a fast non-genetic response to environmental modifications that can buffer the effects of environmental stresses on populations. However, little is known about the evolution of plasticity in the absence of standing genetic variation although several non-genetic inheritance mechanisms have now been identified. Here we monitored the pea aphid transgenerational phenotypic response to ladybird predators (production of winged offspring) during 27 generations of experimental evolution in the absence of initial genetic variation (clonal multiplication starting from a single individual).

Uropygial gland size and composition varies according to experimentally modified microbiome in Great tits.

Background: Parasites exert important selective pressures on host life history traits. In birds, feathers are inhabited by numerous microorganisms, some of them being able to degrade feathers or lead to infections. Preening feathers with secretions of the uropygial gland has been found to act as an antimicrobial defence mechanism, expected to regulate feather microbial communities and thus limit feather abrasion and infections.

[Learning curve in sialendoscopy: Our first 101 procedures].

Objective: To present our learning curve in diagnostic and interventional sialendoscopy for obstructive salivary diseases.

Materials And Methods: Monocentric descriptive retrospective study from March 2009 to July 2011. Clinical and demographic data were collected.

Drug exposure and perceived adverse drug events reported by liver-transplant patients.

Introduction: Posttransplant patient outcome and quality of life are affected by different factors, such as post-graft context, psychological state, and polymedication. Many surveys have been carried out to study immunosuppressant ADRs, and have mainly used a questionnaire completed by patients, but few have asked patients about their drug exposure. The aim of this study is to describe drug exposure and adverse drug events (ADEs) reported by liver-transplant patients (LTP).
