Study of the energy dependence of the underlying event in proton-antiproton collision
We study charged particle production (pT>0.5??GeV/c, |?|<0.8) in proton-antiproton collisions at total center-of-mass energies vs=300??GeV, 900 GeV, and 1.96 TeV. We use the direction of the charged particle with the largest transverse momentum in each event to define three regions of ?-? space: “toward”, “away”, and “transverse.” The average number and the average scalar pT sum of charged particles in the transverse region are sensitive to the modeling of the “underlying event.” The transverse region is divided into a MAX and MIN transverse region, which helps separate the “hard component” (initial and final-state radiation) from the “beam-beam remnant” and multiple parton interaction components of the scattering. The center-of-mass energy dependence of the various components of the event is studied in detail. The data presented here can be used to constrain and improve QCD Monte Carlo models, resulting in more precise predictions at the LHC energies of 13 and 14 TeV.We thank the Fermilab staff and the technical staffs of theparticipating institutions for their vital contributions.

Neuronal and astrocytic involvement in striped dolphins (Stenella coeruleoalba) with morbilliviral encephalitis.
Dolphin morbillivirus (DMV), a highly pathogenic agent, may cause peculiar, "brain-only" forms of infection (BOFDI), in which viral antigen and/or genome is found exclusively in the brain from striped dolphins (Stenella coeruleoalba). These BOFDIs show morphopathological similarities with subacute sclerosing panencephalitis and old dog encephalitis (ODE) in measles virus-infected patients and in canine distemper virus-infected dogs, respectively. The brain tissue from 3 BOFDI-affected striped dolphins was investigated by means of double labelling-indirect immunofluorescence (DL-IIF) and ultrastructurally, in order to characterize the DMV-targeted neuronal and non-neuronal cell populations, along with the associated submicroscopic findings. Viral colonization of calbindin-immunoreactive (IR) and nitric oxide synthase-IR neurons was detected in the cerebral parenchyma from the 3 DMV-infected dolphins under study, associated with nuclear (chromatin) and cytoplasmic (mitochondrial) ultrastructural changes. Furthermore, a limited viral targeting of brain astrocytes was found in these animals, all of which exhibited a prominent astrogliosis/astrocytosis. To the best of our knowledge, those herein reported should be the first submicroscopic pathology and neuropathogenetic data about BOFDI in striped dolphins. In this respect, the marked astrogliosis/astrocytosis and the low viral colonization of brain astrocytes in the 3 DMV-infected dolphins under investigation are of interest from the comparative pathology and viral neuropathogenesis standpoints, when compared with ODE-affected dogs, in whose brain a non-cytolytic, astrocyte-to-astrocyte infectious spread has been recently documented. Further studies aimed at characterizing the complex DMV-host interactions in BOFDI-affected striped dolphins are needed
Novel therapeutic protocol in the research of breast cancer treatment - Targeting the border
Healthcare practices and Human-Centred Management principles during the COVID-19 pandemic. The Italian experience.
This book is part of the Human Centered Book Trilogy, the 2021 volumes of the Routledge Human Centered Management HCM Series. HCM books are pioneering transformation from the traditional humans-as-a-resource approach of the industrial past, to the humans at the center management and organizational paradigm of the 21st century. HCM is built on talent and wellbeing of people in the workplace driving work engagement, quality standards, high performance and productivity for long-term organizational sustainability in the global VUCA (volatile, uncertain, complex, ambiguous) environment.
This book was carefully crafted by recognized international human centered scholars from four continents. Although all organizations seek to have an optimal culture, unstoppable disruptions in the VUCA environment easily derail even the best efforts. Conventional assumptions of culture as a unifying organizational force are hardly defendable today. HCM maintains that culture is not only about cohesiveness and consensus but effective management of conflict and disagreements continuously testing the capacity of people to work together. This book is about organizational transformation positioning people at the center. Complementary chapters integrate as antidotes to overcome disruptions in the VUCA environment and the effects of the COVID-19 pandemic affecting people and organizations worldwide.
This and its two complementary titles Soft Skills for Human Centered Management and Global Sustainability and Sensible Leadership: Human Centered, Insightful and Prudent are timely readings for leaders, managers, researchers, academics, practitioners, students and the general public responsible for organizations across industries and sectors worldwide pursuing quality standards and organizational transformation to attain sustaina

FMRP regulates multipolar to bipolar transition affecting neuronal migration and cortical circuitry
Deficiencies in fragile X mental retardation protein (FMRP) are the most common cause of inherited intellectual disability, fragile X syndrome (FXS), with symptoms manifesting during infancy and early childhood. Using a mouse model for FXS, we found that Fmrp regulates the positioning of neurons in the cortical plate during embryonic development, affecting their multipolar-to-bipolar transition (MBT). We identified N-cadherin, which is crucial for MBT, as an Fmrp-regulated target in embryonic brain. Furthermore, spontaneous network activity and high-resolution brain imaging revealed defects in the establishment of neuronal networks at very early developmental stages, further confirmed by an unbalanced excitatory and inhibitory network. Finally, reintroduction of Fmrp or N-cadherin in the embryo normalized early postnatal neuron activity. Our findings highlight the critical role of Fmrp in the developing cerebral cortex and might explain some of the clinical features observed in patients with FXS, such as alterations in synaptic communication and neuronal network connectivity
