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...

BACKGROUND AND AIM: Parkinson's disease (PD) patients have impairment of facial expressivity (hypomimia) and difficulties in interpreting the emotional facial expressions produced by others, especially for aversive emotions. We aimed to evaluate the ability to produce facial emotional expressions and to recognize facial emotional expressions produced by others in a group of PD patients and a group of healthy participants in order to explore the relationship between these two abilities and any differences between the two groups of participants...

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)...

Luteinizing hormone (LH) is crucial for the development of follicular growth and oocyte maturation, especially in the management of poor ovarian responders (PORs). This study presents the results of a prospective double-blinded randomized study to compare the effect of mid-follicular phase recombinant LH (rLH) supplementation with urinary human chorionic gonadotrophin (uHCG) supplementation when using a fixed gonadotrophin-releasing hormone (GnRH) antagonist protocol in IVF cycles. A total of 49 women with poor ovarian response (POR) according to the Bologna criteria were recruited...

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...

Nocturnal frontal lobe epilepsy (NFLE) is a focal epilepsy with seizures arising mainly during sleep and characterized by complex, often bizarre, motor behavior or sustained dystonic posturing. First described in 1981, it was initially considered a motor disorder of sleep and was named nocturnal paroxysmal dystonia (NPD). The unusual seizure semiology, onset during sleep, and often uninformative scalp EEG and brain MRI make it difficult to distinguish NPD attacks from other non-epileptic nocturnal paroxysmal events, namely parasomnias...

BACKGROUND: Altered emotional processing, including reduced emotion facial expression and defective emotion recognition, has been reported in patients with Parkinson's disease (PD). However, few studies have objectively investigated facial expression abnormalities in PD using neurophysiological techniques. It is not known whether altered facial expression and recognition in PD are related. OBJECTIVE: To investigate possible deficits in facial emotion expression and emotion recognition and their relationship, if any, in patients with PD...

Even if NOTCH1 is commonly mutated in Chronic Lymphocytic Leukemia (CLL), its functional impact in the disease remains unclear. Using CRISPR/Cas9-generated Mec-1 cell line models, we show that NOTCH1 regulates growth and homing of CLL cells by dictating expression levels of the tumor suppressor gene DUSP22. Specifically, NOTCH1 affects the methylation of DUSP22 promoter by modulating a nuclear complex, which tunes the activity of DNA methyltransferase 3A (DNMT3A). These effects are enhanced by PEST-domain mutations, which stabilize the molecule and prolong signaling...

Plant RNA silencing operates via RNA-directed DNA-methylation (RdDM) to repress transcription or by targeting mRNAs via posttranscriptional gene silencing (PTGS). These pathways rely on distinct Dicer-like (DCL) proteins that process double-stranded RNA (dsRNA) into small-interfering RNAs (siRNAs). Here, we explored the expression and subcellular localization of Arabidopsis thaliana DCL4. DCL4 expression predominates as a transcription start site isoform encoding a cytoplasmic protein, which also represents the ancestral form in plants...
