Abstract MYCN gene amplification is consistently associated with poor prognosis in patients with neuroblastoma, a pediatric tumor arising from the sympathetic nervous system. Conventional anticancer drugs, such as alkylating agents and platinum compounds, have been used for the treatment of high‐risk patients with MYCN‐amplified neuroblastoma, whereas molecule‐targeting drugs have not yet been approved. Therefore, the development of a safe and effective therapeutic approach is highly desired. Although...
Abstract As the core element of material and energy metabolism pathways, the biological functions and prognostic significance of ATP metabolism have so far remained unclear in diffuse gliomas. Here, we found that ATP metabolism‐related genes could divide patients into two robust groups with distinct clinical characteristics and prognosis. Base on comprehensive analysis of ATP metabolism‐related genes expression profile, we constructed an ATP metabolism‐related risk signature to determine the role...
Abstract HER4 isoforms have oncogenic or tumor suppressor functions depending on their susceptibility to proteolytic cleavage and HER4 Intracellular Domain (4ICD) translocation. Here, we report that the NRG1 tumor suppressor mechanism through the HER4 JMa/CYT1 isoform can be mimicked by the agonist anti‐HER4 antibody C6. NRG1 induced cleavage of poly(ADP‐ribose) polymerase (PARP) and sub‐G1 DNA fragmentation, and also reduced the metabolic activity of HER3‐negative/HER4‐positive cervical (C‐33A)...
Abstract Secondary lymphedema often develops after cancer surgery, and over 250 million patients suffer from this complication. A major symptom of secondary lymphedema is swelling with fibrosis, which lowers the patient’s quality of life, even if cancer does not recur. Nonetheless, the pathophysiology of secondary lymphedema remains unclear, with therapeutic approaches limited to physical or surgical therapy. There is no effective pharmacological therapy for secondary lymphedema. Notably, the lack...
Abstract Dietary factors may affect the prognosis of digestive tract cancer, but evidence has been sparse. Focusing on Japanese diet, we investigated the association between pretreatment intake of six Japanese foods (including soy food, miso (soybean paste) soup and seaweed) and the risk of death among patients with histologically confirmed major digestive tract cancers (stomach, 1931; colon, 793; rectum, 510) diagnosed during 1997‐2013 at a single institution in Japan. Pretreatment dietary intake...

Wetland ecosystems have been globally degraded and lost due to rapid urbanization and climate change. An assessment of national scale inventory, including wetland types and conditions, is urgently required to understand the big picture of endangered wetlands, such as where they are and how they look like. We analyzed the spatial patterns of each inland wetland type (brackish wetland was included) in South Korea and the relative importance of land cover categories on wetland conditions. The wetlands...
Background In the last decades, Italy as well as other developed countries have registered a decrease in the population size of many local horse breeds. The continuous crossbreeding has determined the dilution of genetic heritage of several native breeds. The Italian Heavy Draught Horse (IHD) is the only autochthonous Italian coldblooded horse among these breeds; therefore, it represents a resource to be preserved. In 1927, the first generation of this breed was officially created...
Despite evidence from anatomy, behavior and genomics indicating that the sense of smell in turtles is important, our understanding of chemical communication in this group is still rudimentary. Our aim was to describe the microanatomy of mental glands (MGs) in a freshwater turtle, Mauremys leprosa (Geoemydidae), and to assess the chemical composition of their secretions with respect to variation among individuals and between sexes. MGs are paired sac-like organs on the gular region of the neck and...
Background “Quantile-dependent expressivity” refers to a genetic effect that is dependent upon whether the phenotype (e.g., spirometric data) is high or low relative to its population distribution. Forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and the FEV1/FVC ratio are moderately heritable spirometric traits. The aim of the analyses is to test whether their heritability (h2) is constant over all quantiles of their distribution. ...
Galeaspids are an endemic clade of jawless stem-gnathostomes known as ostracoderms. Their existence illuminates how specific characteristics developed in jawed vertebrates. Sinogaleaspids are of particular interest among the galeaspids but their monophyly is controversial because little is known about Sinogaleaspis xikengensis. Newly discovered sinogaleaspids from the Lower Silurian of Jiangxi, China provide a wealth of data and diagnostic features used to establish the new genus, Rumporostralis...
Melanin is the main pigment of human skin, playing the primary role of protection from ultraviolet radiation. Alteration of the melanin production may lead to hyperpigmentation diseases, with both aesthetic and health consequences. Thus, suppressors of melanogenesis are considered useful tools for medical and cosmetic treatments. A great interest is focused on natural sources, aimed at finding safe and quantitatively available depigmenting substances. Lichens are thought to be possible sources of...

Covid‐19 infection has the potential for targeting the central nervous system and several neurological symptoms have been described in patients with severe respiratory distress. Here we described the case of a 60‐year old subject with SARS‐CoV‐2 infection but only mild respiratory abnormalities who developed an akinetic mutism due to encephalitis. MRI was negative whereas EEG showed generalized theta slowing. CSF analyses during the acute stage were negative for SARS‐CoV‐2, positive for pleocytosis...
Objective Myotonia is caused by involuntary firing of skeletal muscle action potentials and causes debilitating stiffness. Current treatments are insufficiently efficacious and associated with side effects. Myotonia can be triggered by voluntary movement (electrically‐induced myotonia) or percussion (mechanically‐induced myotonia). Whether distinct molecular mechanisms underlie these triggers is unknown. Our goal was to identify ion channels involved in mechanically‐induced myotonia and to evaluate...

Abstract Coronavirus disease 2019 (COVID‐19) pandemic is affecting people at any age with a more severe course in patients with chronic diseases or comorbidities, males and elderly patients. The Center for Disease Control and Prevention (CDC) initially proposed that patients with chronic lung diseases, including moderate‐severe asthma, and allergy may have a higher risk of developing severe COVID‐19 than otherwise healthy people (https://www.cdc.gov/coronavirus/2019-ncov/specific-groups/asthma.html).
Abstract Hypereosinophilic syndrome (HES) is a group of rare disorders characterized by persistently elevated eosinophil count and eosinophil‐mediated organ damage. The most frequent symptoms are cutaneous (e.g. urticaria, angioedema) and respiratory (e.g. asthma, sinusitis)1. HES can further cause gastrointestinal, cardiovascular, neurologic, and hematologic involvement, with cardiac manifestations having the most significant implications in terms of morbidity and mortality2. While population‐based...

Abstract Background Interleukin‐7 (IL‐7) is the most important cytokine for T cell homeostasis. IL‐7 signals through the IL‐7 receptor (IL‐7R) which is composed of an alpha chain (IL‐7Rα), also called CD127 and a common gamma chain. T lymphocytes, especially T helper type 2, play a crucial role in the pathobiology of allergic asthma. Objective To study the effects of an anti‐CD127 monoclonal antibody (mAb) in a murine model of allergic airway inflammation induced by house dust mite (HDM)....
Abstract Background Chronic spontaneous urticaria (CSU) is considered an autoimmune disorder in 50% of cases at least, in which T and mast cell mediators are considered to be the primary cause of symptoms. However, H1‐antihistamines, cyclosporine A and omalizumab fail to achieve complete symptom amelioration in up to 70% of patients. This suggests that other inflammatory pathways are involved and that additional and more effective treatments need to be developed. Objective This preliminary...
