The EXcellenT Trial: Exercise in Extended Oncogene Addicted Lung Cancer in Active Treatment.

Introduction: The discovery of oncogenic mutations that drive the growth and progression of Non-small-cell lung cancer (NSCLC) led to the development of a range of molecular targeted therapies. Tyrosine kinase inhibitors (TKIs) improve the overall outcome of patients with oncogene addicted NSCLC, ensure a better compliance to treatment and few side effects compared to traditional chemotherapy. However, the treatment is still completely "drug-centric", in a population of patients who usually survive for a long time and desire to regain their quality of life.

Circulating programmed death ligand-1 (cPD-L1) in non-small-cell lung cancer (NSCLC).

Background: This study aimed at investigating feasibility of programmed death ligand-1 (PD-L1) testing in plasma samples of advanced NSCLC patients receiving first-line treatment, assessing whether circulating (c)PD-L1 levels were modified by the therapy and whether baseline cPD-L1 levels were associated with patients' clinical responses and survival outcome.

Methods: Peripheral blood samples were collected from 16 healthy volunteers and 56 newly diagnosed NSCLC patients before and at 12th week during the course of first-line therapy. The level of PD-L1 was measured in plasma samples using the human (PD-L1/CD274) ELISA kit (CUSABIO, MD, USA).

Calls during agonistic interactions vary with arousal and raise audience attention in ravens.

Background: Acoustic properties of vocalizations can vary with the internal state of the caller, and may serve as reliable indicators for a caller's emotional state, for example to prevent conflicts. Thus, individuals may associate distinct characteristics in acoustic signals of conspecifics with specific social contexts, and adjust their behaviour accordingly to prevent escalation of conflicts. Common ravens () crowd-forage with individuals of different age classes, sex, and rank, assemble at feeding sites, and engage in agonistic interactions of varying intensity.

With whom to dine? Ravens' responses to food-associated calls depend on individual characteristics of the caller.

Upon discovering food, common ravens, , produce far-reaching 'haa' calls or yells, which are individually distinct and signal food availability to conspecifics. Here, we investigated whether ravens respond differently to 'haa' calls of known and unknown individuals. In a paired playback design, we tested responses to 'haa' call sequences in a group containing individually marked free-ranging ravens.

Ravens intervene in others' bonding attempts.

The competition for power in a complex social world is hypothesized to be a driving force in the evolution of intelligence. More specifically, power may be obtained not only by brute force but also by social strategies resembling human politics. Most empirical evidence comes from primate studies that report unprovoked aggression by dominants to maintain power by spreading fear and third-party interventions in conflicts.
