Beyond Wolfram Syndrome 1: The Gene's Role in Alzheimer's Disease and Sleep Disorders.

The gene was first identified in Wolfram Syndrome 1 (WS1), a rare autosomal recessive genetic disorder characterized by severe and progressive neurodegenerative changes. 's role in various cellular mechanisms, particularly in calcium homeostasis and the modulation of endoplasmic reticulum (ER) stress, suggests its potential involvement in the pathogenesis of Alzheimer's disease (AD) and sleep disorders. Because it is involved in maintaining ER balance, calcium signaling, and stress responses, plays a multifaceted role in neuronal health.

Needs of female outpatients with alcohol use disorder: data from an Italian study.

Aims: Alcohol use disorder (AUD) is a common mental disorder characterized by sex-gender differences (SGDs). The present study was aimed at evaluating attitudes displayed by Italian AUD treatment services towards investigating the presence of SGDs in their patients and implementing gender-specific treatments for female AUD patients.

Methods: Potential SGDs were initially investigated in a sample of AUD outpatients, subsequently followed by a national survey on the adoption of specific interventions for female AUD outpatients.

Ultrastructural Evidence of Eosinophil Clustering and ETosis in Association with Damage to Single Tumour Cells in a Case of Poorly Cohesive NOS Gastric Carcinoma.

Unlabelled: A case of poorly cohesive NOS gastric carcinoma, characterised by high-grade tumour-associated tissue eosinophilia (TATE), is studied by transmission electron microscopy. Eosinophil clustering around single tumour cells constituted a recurrent ultrastructural hallmark. Some eosinophils were in intimate contact with tumour cells and exhibited extracellular trap cell death (ETosis): a non-apoptotic cell death process, recently described in non-neoplastic, eosinophil-associated diseases.

Wolfram Syndrome 1: From Genetics to Therapy.

Wolfram syndrome 1 (WS1) is a rare neurodegenerative disease transmitted in an autosomal recessive mode. It is characterized by diabetes insipidus (DI), diabetes mellitus (DM), optic atrophy (OA), and sensorineural hearing loss (D) (DIDMOAD). The clinical picture may be complicated by other symptoms, such as urinary tract, endocrinological, psychiatric, and neurological abnormalities.

An Atypical Case of Late-Onset Wolfram Syndrome 1 without Diabetes Insipidus.

Wolfram syndrome 1, a rare autosomal recessive neurodegenerative disease, is caused by mutations in the gene. It is characterized by diabetes insipidus, diabetes mellitus, optic atrophy, and deafness (DIDMOAD), and other clinical manifestations such as urological and neurological disorders. Here we described the case of a patient with an atypical late-onset Wolfram syndrome 1 without DI.

Eosinophil exocytosis in a poorly differentiated tubular gastric adenocarcinoma: case report.

A case of poorly differentiated tubular gastric adenocarcinoma with tumor-associated tissue eosinophilia (TATE) is studied by light and electron microscopy, focusing on membrane interactions between eosinophils and tumor cells. 29.2% of the eosinophils in contact with tumor cells showed intact granules, 28.

Clinical Peculiarities in a Cohort of Patients with Wolfram Syndrome 1.

Wolfram syndrome 1 is a rare, autosomal recessive, neurodegenerative, progressive disorder. Insulin-dependent, non-autoimmune diabetes mellitus and bilateral progressive optic atrophy are both sensitive and specific criteria for clinical diagnosis. The leading cause of death is central respiratory failure resulting from brainstem atrophy.

Navigational Behavior of Humans and Deep Reinforcement Learning Agents.

Rapid advances in the field of Deep Reinforcement Learning (DRL) over the past several years have led to artificial agents (AAs) capable of producing behavior that meets or exceeds human-level performance in a wide variety of tasks. However, research on DRL frequently lacks adequate discussion of the low-level dynamics of the behavior itself and instead focuses on meta-level or global-level performance metrics. In doing so, the current literature lacks perspective on the qualitative nature of AA behavior, leaving questions regarding the spatiotemporal patterning of their behavior largely unanswered.

Synchronous vs. non-synchronous imitation: Using dance to explore interpersonal coordination during observational learning.

Observational learning can enhance the acquisition and performance quality of complex motor skills. While an extensive body of research has focused on the benefits of synchronous (i.e.

Co-actors Exhibit Similarity in Their Structure of Behavioural Variation That Remains Stable Across Range of Naturalistic Activities.

Human behaviour, along with any natural/biological behaviour, has varying degrees of intrinsic 'noise' or variability. Many studies have shown that the structure or patterning of this variability is sensitive to changes in task and constraint. Furthermore, two or more humans interacting together often begin to exhibit similar structures of behavioural variability (i.

Evolutionarily-Related Genotypes and Gastric Intraepithelial Neoplasia in a High-Risk Area of Northern Italy.

() is the major recognized risk factor for non-cardia gastric cancer (GC), but only a fraction of infected subjects develop GC, thus GC risk might reflect other genetic/environmental cofactors and/or differences in virulence among infectious strains. Focusing on a high GC risk area of Northern Italy (Cremona, Lombardy) and using archived paraffin-embedded biopsies, we investigated the associations between the and genotype variants and gastric intraepithelial neoplasia (GIN, 33 cases) versus non-neoplastic gastroduodenal lesions (NNGDLs, 37 cases). The gene and the and (s and m) genotypes were determined by polymerase chain reaction (PCR) and sequencing.

Iron overload and malignancies in patients with haemoglobinopathies: A single center experience.

Thalassemias and sickle cell disease are a group of inherited blood disorders caused by alterations of the synthesis or of the structure of hemoglobin chains. It results in variable outcomes ranging from severe anemia to clinically asymptomatic individuals. Hemolysis and transfusions therapies lead to iron overload and, thus, to an high production of reactive oxygen species (ROS).

Wolfram syndrome 1 in the Italian population: genotype-phenotype correlations.

Objectives: We studied 45 patients with Wolfram syndrome 1 (WS1) to describe their clinical history and to search for possible genotype-phenotype correlations.

Methods: Clinical criteria contributing to WS1 diagnosis were analyzed. The patients were classified into three genotypic classes according to type of detected mutations.

.

In neoplastic conditions, autophagy may act as a tumor suppressor avoiding the accumulation of damaged proteins and organelles or as a mechanism of cell survival promoting the tumor growth. Although ultrastructural analysis has been considered the traditional method to identify autophagy, some proteins such as microtubule-associated protein 1 light chain 3 (LC3A/B), Beclin-1 and activating molecule in Beclin-1-regulated autophagy protein-1 (AMBRA-1) may be considered as markers of autophagy-assisted cancerogenesis. Herein, we analyzed a cohort of advanced tubular gastric adenocarcinomas by the abovementioned immunohistochemical antisera; through immunohistochemistry, autophagy (A-IHC) is diagnosed when at least two out of the three proteins are positive in the samples.

The original version of this Article erroneously cropped part of the abstract. The abstract has now been corrected to read 'Wolfram syndrome 1 (WS1) is a rare autosomal recessive neurodegenerative disease characterized by diabetes insipidus, diabetes mellitus, optic atrophy, deafness, and other abnormalities. WS1 usually results in death before the age of 50 years.

Genetic and clinical aspects of Wolfram syndrome 1, a severe neurodegenerative disease.

Wolfram syndrome 1 (WS1) is a rare autosomal recessive neurodegenerative disease characterized by diabetes insipidus, diabetes mellitus, optic atrophy, deafness, and other abnormalities. WS1 usually results in death before the age of 50 years. The pathogenesis of WS1 is ascribed to mutations of human WFS1 gene on chromosome 4p encoding a transmembrane protein called wolframin, which has physiological functions in membrane trafficking, secretion, processing, and/or regulation of ER calcium homeostasis.

Morphological and Cellular Features of Innate Immune Reaction in Helicobacter pylori Gastritis: A Brief Review.

Innate and adaptive immunity are both involved in acute and chronic inflammatory processes. The main cellular players in the innate immune system are macrophages, mast cells, dendritic cells, neutrophils, eosinophils, and natural killer (NK), which offer antigen-independent defense against infection. Helicobacter pylori (H.

HER2 Status in Premalignant, Early, and Advanced Neoplastic Lesions of the Stomach.

Objectives: HER2 expression in gastric cancer (GC) has received attention as a potential target for therapy with Trastuzumab. We reviewed the current knowledge on HER2 status in premalignant gastric lesions and in early (EGC) and advanced (AGC) GC to discuss the possible pathogenetic and prognostic roles of HER2 overexpression in GC.

Results: HER2 overexpression was documented in gastric low-grade (LG) and high-grade intraepithelial neoplasia (HG-IEN), with higher frequency in gastric type dysplasia.

Mutations in the gene encoding the gap junction protein connexin 26 (GJB2) and connexin 30 (GJB6) have been shown to be a major contributor to prelingual, sensorineural, nonsyndromic deafness. The aim of this study was to characterize and establish the prevalence of GJB2 and GJB6 gene alterations in 196 patients affected by sensorineural, nonsyndromic hearing loss, from Eastern Sicily. We performed sequence analysis of GJB2 and identified sequence variants in 68 out of 196 patients (34.

Thalassaemia major and infectious risk: High Mobility Group Box-1 represents a novel diagnostic and prognostic biomarker.

High mobility group box -1 (HMGB1) represents a common causal agent for various types of diseases, including infective pathologies. This study aimed to investigate the role of HMGB1 in β-thalassemia major (TM) by evaluating its diagnostic and prognostic role. Fifty-one TM patients and 30 healthy subjects (HS) were enrolled.

Phagocytosis (cannibalism) of apoptotic neutrophils by tumor cells in gastric micropapillary carcinomas.

Aim: To identify those with a micropapillary pattern, ascertain relative frequency and document clinicopathological characteristics by reviewing gastric carcinomas.

Methods: One hundred and fifty-one patients diagnosed with gastric cancer who underwent gastrectomy were retrospectively studied and the presence of a regional invasive micropapillary component was evaluated by light microscopy. All available hematoxylin-eosin (HE)-stained slides were histologically reviewed and 5 tumors were selected as putative micropapillary carcinoma when cancer cell clusters without a vascular core within empty lymphatic-like space comprised at least 5% of the tumor.

Deferiprone versus deferoxamine in thalassemia intermedia: Results from a 5-year long-term Italian multicenter randomized clinical trial.

In patients with thalassemia intermedia (TI), such as beta-TI, alpha-thalassemia (mainly HbH disease and mild/moderate forms of HbE/beta-thalassemia), iron overload is an important challenge in terms of diagnosis, monitoring, and treatment. Moreover, to date, the only possible chelators available are deferoxamine, deferasirox, and deferiprone. Here, we report the first 5-year long-term randomized clinical trial comparing the effectiveness of deferiprone versus deferoxamine in patients with TI.
