PD-L1 is expressed by a subset of patients with metastatic melanoma (MM) with an unfavorable outcome. Its expression is increased in cells resistant to BRAF or MEK inhibitors (BRAFi or MEKi). However, the function and regulation of expression of PD-L1 remain incompletely understood.After generating BRAFi- and MEKi-resistant cell lines, we observed marked up-regulation of PD-L1 expression. These cells were characterized by a common gene expression profile with up-regulation of genes involved in cell movement...

Yuejia Lee, Chinling Wang
Listeria monocytogenes , a lethal foodborne pathogen, has the ability to resist the hostile food processing environment and thus frequently contaminates ready-to-eat foods during processing. It is commonly accepted that the tendency of L. monocytogenes ' to generate biofilms on various surfaces enhances its resistance to the harshness of the food processing environment. However, the role of biofilm formation in the transferability of L. monocytogenes EGDe remains controversial. We examined the growth of Listeria biofilms on stainless steel surfaces and their effect on the transferability of L...

Complex lesions of the thoracic aorta are traditionally treated in 2 surgical steps with the elephant trunk technique. A relatively new approach is the frozen elephant trunk (FET) technique, which potentially allows combined lesions of the thoracic aorta to be treated in a 1-stage procedure combining endovascular treatment with conventional surgery using a hybrid prosthesis. These are very complex and time-consuming operations, and good results can be obtained only if appropriate strategies for myocardial, cerebral, and visceral protection are adopted...

The current study aimed to investigate the effects of luteal gonadotropin-releasing hormone (GnRH) antagonist pretreatment on the outcomes of diminished ovarian reserve (DOR) patients who were treated using a FSH/letrozole/GnRH antagonist (FLA) protocol. Thus, patients who had luteal GnRH antagonist pretreatment (AFLA) prior to stimulation were compared to patients who had the FLA protocol, only. An electronic database was used to identify patients and stimulation characteristics. Women who had a total antral follicle count (AFC) of <7 were included in the analysis...

BACKGROUND: The unrivalled conquests of Genghis Khan (CE c.1162-1227) led to the establishment of the Greater Mongolian Empire. By 1279, the Mongol dynasty controlled a vast Empire which, for the first time in history, unified Europe and China via the famous Silk Road. The ensuing century of peace and stability is referred to by historians as the Pax Mongolica, which facilitated Europe's renaissance and remarkably contributed to the rise of modern medicine and surgery. METHODS: Secondary sources from published literature, primary sources from manuscripts and illustrations courtesy of universities, museum libraries and archives...

BACKGROUND: Several studies have shown that patients with non-erosive reflux disease (NERD) are less responsive to proton pump inhibitors (PPIs) than those with erosive disease as they belong to different subgroups, in whom factors other than acid can trigger symptoms. AIM: To evaluate whether combined therapy (mucosal protection plus acid suppression) would improve symptom relief compared to PPI treatment alone. METHODS: In a multicenter, randomised, double-blind trial, 154 patients with NERD were randomised to receive Esoxx (Alfa Wassermann, Bologna, Italy), a hyaluronic acid-chondroitin sulphate based bioadhesive formulation, or placebo, in addition to acid suppression with standard dose PPIs for 2 weeks...

BACKGROUND: The clinical-epidemiological characteristics and course of bullous pemphigoid in the general population is not clear. Few studies have been performed to date, and only one in the Italian population more than ten years ago. We decided to evaluate the characteristics and outcome of patients admitted for a bullous pemphigoid at our Hospital in the last 4 years. METHODS: We retrospectively review the last 4 years' medical records of the Department of Dermatology of the University of Bologna, identifying all patients with histological and immunological data typical for bullous pemphigoid...

Myrmecochory is the process of seed dispersal by ants; however, it is highly challenging to study, mainly because of the small size of both partners and the comparatively large range of dispersal. The mutualistic interaction between ants and seeds involves the former retrieving diaspores, consuming their elaiosome (a nutrient-rich appendage), and the rejection of seeds from the nest. Here, we introduce a semi-automated method based on stitching high resolution images together, allowing the study of myrmecochory in a controlled environment over time...

OBJECTIVE: START (Simple Triage and Rapid Treatment) triage is a tool that is available even to nonmedical rescue personnel in case of a disaster or mass casualty incident (MCI). In Italy, no data are available on whether application of the START protocol could improve patient outcomes during a disaster or MCI. We aimed to address whether "last-minute" START training of nonmedical personnel during a disaster or MCI would result in more effective triage of patients. METHODS: In this case-control study, 400 nonmedical ambulance crew members were randomly assigned to a non-START or a START group (200 per group)...

Childhood obesity is commonly associated with early signs of endothelial dysfunction, characterized by impairment of insulin signaling and vascular Nitric Oxide (NO) availability. However, the underlying mechanisms remain to be established. Hence, we tested the hypothesis that endothelial insulin-stimulated NO production and availability was impaired and related to Endoplasmic Reticulum (ER) in human umbilical vein endothelial cells (HUVECs) cultured with plasma obtained from pre-pubertal obese (OB) children...

BACKGROUND: In 2011 we reported a rituximab plus miniCHOP (reduced-dose cyclophosphamide, doxorubicin, vincristine, and prednisone) combination for patients older than 80 years with diffuse large B-cell lymphoma (DLBCL). The 2-year overall survival was 59% (95% CI 49-67) with an excess of early toxicity. To improve those results we tested the same chemotherapy protocol in combination with ofatumumab and a pre-phase treatment. METHODS: For this open-label, multicentre, single-group, phase 2 trial, we recruited patients older than 80 years with untreated histologically-proven CD20-positive DLBCL, Ann Arbor stage I to IV, from 41 academic and hospital centres in France and Belgium...

G protein-coupled receptors (GPCRs) are a family of cell-surface proteins that play critical roles in regulating a variety of pathophysiological processes and thus are targeted by almost a third of currently available therapeutics. It was originally thought that GPCRs convert extracellular stimuli into intracellular signals through activating G proteins, whereas β-arrestins have important roles in internalization and desensitization of the receptor. Over the past decade, several novel functional aspects of β-arrestins in regulating GPCR signaling have been discovered...
