Shotgun proteomics coupled to nanoparticle-based biomarker enrichment reveals a novel panel of extracellular matrix proteins as candidate serum protein biomarkers for early-stage breast cancer detection.

Background: The lack of specificity and high degree of false positive and false negative rates when using mammographic screening for detecting early-stage breast cancer is a critical issue. Blood-based molecular assays that could be used in adjunct with mammography for increased specificity and sensitivity could have profound clinical impact. Our objective was to discover and independently verify a panel of candidate blood-based biomarkers that could identify the earliest stages of breast cancer and complement current mammographic screening approaches.

Thymosin alpha 1 exerts beneficial extrapulmonary effects in cystic fibrosis.

Cystic fibrosis (CF) is an autosomal recessive disorder caused by mutations in the gene encoding for the ion channel Cystic Fibrosis Transmembrane conductance Regulator (CFTR). Long considered a lung disease for the devastating impact on the respiratory function, the recent diagnostic and therapeutic advances have shed the light on the extra-pulmonary manifestations of CF, including gastrointestinal, hepatobiliary and pancreatic symptoms. We have previously demonstrated that thymosin alpha1 (Tα1), a naturally occurring immunomodulatory peptide, displays multi-sided beneficial effects in CF that concur in ameliorating the lung inflammatory pathology.

Methods: A stone-cast model of a totally edentulous maxilla with 6 implant analogues and scanbodies (SBs) was scanned with a desktop scanner (Freedom UHD®) to capture a reference model (RM), and with 12 IOSs (ITERO ELEMENTS 5D®; PRIMESCAN® and OMNICAM®; CS 3700® and CS 3600®; TRIOS3®; i-500®; EMERALD S® and EMERALD®; VIRTUO VIVO® and DWIO®; RUNEYES QUICKSCAN®).

Prognostic role of ultrasonography staging in patients with anal cancer.

Background: Carcinomas of the anal canal are staged according to the size and extent of the disease; however, we propose including a novel ultrasound (US) staging system, based on depth of tumor invasion. In this study the clinical American Joint Committee on Cancer (AJCC) staging guidelines and the US classificationss in patients with anal cancer were compared.

Aim: To evaluate the prognostic role of the US staging system in patients with anal cancer.

Thymosin α1 protects from CTLA-4 intestinal immunopathology.

The advent of immune checkpoint inhibitors has represented a major boost in cancer therapy, but safety concerns are increasingly being recognized. Indeed, although beneficial at the tumor site, unlocking a safeguard mechanism of the immune response may trigger autoimmune-like effects at the periphery, thus making the safety of immune checkpoint inhibitors a research priority. Herein, we demonstrate that thymosin α1 (Tα1), an endogenous peptide with immunomodulatory activities, can protect mice from intestinal toxicity in a murine model of immune checkpoint inhibitor-induced colitis.

Laparoscopic Sleeve Gastrectomy (LSG) is one of the most performed surgical procedures in bariatric surgery. Staple line leak and bleeding are by far the two most feared complications after LSG. In this study, we retrospectively compared the efficacy of Fibrin Glue in preventing staple line leak and bleeding.

Analysis of Narrow-Leaf Lupin Proteins in Lupin-Enriched Pasta by Untargeted and Targeted Mass Spectrometry.

The supplementation of different food items with grain legumes and, in particular, with lupin has been demonstrated to provide useful health benefits, especially in the area of cardiovascular disease prevention. In this work, label free quantitative untargeted and targeted approaches based on liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) for investigating the protein profile of three pasta samples containing different percentages of narrow-leaf lupin flour were carried out. The untargeted method permitted the identification of the main acidic globulins (α-conglutin, β-conglutin, and δ-conglutin) and the comparison of their profile with raw lupin flour.

A Dynamic Splicing Program Ensures Proper Synaptic Connections in the Developing Cerebellum.

Tight coordination of gene expression in the developing cerebellum is crucial for establishment of neuronal circuits governing motor and cognitive function. However, transcriptional changes alone do not explain all of the switches underlying neuronal differentiation. Here we unveiled a widespread and highly dynamic splicing program that affects synaptic genes in cerebellar neurons.

Effects of safinamide on the glutamatergic striatal network in experimental Parkinson's disease.

Objective: The aim of the study was to evaluate electrophysiological effects of safinamide on the intrinsic and synaptic properties of striatal spiny projection neurons (SPNs) and to characterize the possible therapeutic antiparkinsonian effect of this drug in dopamine (DA) denervated rats before and during levodopa (l-DOPA) treatment.

Background: Current therapeutic options in Parkinson's disease (PD) are primarily DA replacement strategies that usually cause progressive motor fluctuations and l-DOPA-induced dyskinesia (LIDs) as a consequence of SPNs glutamate-induced hyperactivity. As a reversible and use-dependent inhibitor of voltage-gated sodium channels, safinamide reduces the release of glutamate and possibly optimize the effect of l-DOPA therapy in PD.

Assessment of Enzymatic Improvers in Flours Using LC-MS/MS Detection of Marker Tryptic Peptides.

Enzymatic improvers are enzymes obtained from microbial or fungal cultures, added as technical adjuvants to flour, with the aim of improving the dough characteristics in bakery products. They are used in a low ppm range and, being technical adjuvants, can go undeclared on the label. Many types of enzymatic improvers are present on the market, such as amylases, lipases, proteases, xylanases, glucose oxidases, and others, each with a different function.

Frataxin deficiency in Friedreich's ataxia is associated with reduced levels of HAX-1, a regulator of cardiomyocyte death and survival.

Frataxin deficiency, responsible for Friedreich's ataxia (FRDA), is crucial for cell survival since it critically affects viability of neurons, pancreatic beta cells and cardiomyocytes. In FRDA, the heart is frequently affected with typical manifestation of hypertrophic cardiomyopathy, which can progress to heart failure and cause premature death. A microarray analysis performed on FRDA patient's lymphoblastoid cells stably reconstituted with frataxin, indicated HS-1-associated protein X-1 (HAX-1) as the most significantly upregulated transcript (FC = +2, P < 0.

Methods: Echocardiography was performed at baseline (pre-SVR), discharge, and follow-up in 43 patients with ICM and RFP (E/A ratio ≥2). Patients were divided into 2 groups based on E/A ratio at discharge: improved (E/A ratio <2; 22 patients) and unchanged (E/A ratio ≥2; 21 patients).

Hypertension in High School Students: Genetic and Environmental Factors: The HYGEF Study.

Hypertension and obesity in the young population are major risk factors for renal and cardiovascular events, which could arise in adulthood. A candidate-gene approach was applied in a cohort observational study, in which we collected data from 2638 high school adolescent students. Participants underwent anthropometric and blood pressure (BP) measurements, as well as saliva and urine sample collection for genomic DNA extraction and renal function evaluation, respectively.

Thymosin β4 promotes autophagy and repair via HIF-1α stabilization in chronic granulomatous disease.

Chronic granulomatous disease (CGD) is a genetic disorder of the NADPH oxidase characterized by increased susceptibility to infections and hyperinflammation associated with defective autophagy and increased inflammasome activation. Herein, we demonstrate that thymosin β4 (Tβ4), a g-actin sequestering peptide with multiple and diverse intracellular and extracellular activities affecting inflammation, wound healing, fibrosis, and tissue regeneration, promoted in human and murine cells noncanonical autophagy, a form of autophagy associated with phagocytosis and limited inflammation via the death-associated protein kinase 1. We further show that the hypoxia inducible factor-1 (HIF-1)α was underexpressed in CGD but normalized by Tβ4 to promote autophagy and up-regulate genes involved in mucosal barrier protection.

Tumor antigens heterogeneity and immune response-targeting neoantigens in breast cancer.

Breast cancer is both the most common type of cancer and the most frequent cause of cancer mortality in women, mainly because of its heterogeneity and limited immunogenicity. The aim of specific active cancer immunotherapy is to stimulate the host's immune response against cancer cells directly using a vaccine platform carrying one or more tumor antigens. In particular, the ideal tumor antigen should be able to elicit T cell and B cell responses, be specific for the tumor and be expressed at high levels on cancer cells.

Amyloid-β Oligomers-induced Mitochondrial DNA Repair Impairment Contributes to Altered Human Neural Stem Cell Differentiation.

Background: Amyloid-β42 oligomers (Aβ42O), the proximate effectors of neurotoxicity observed in Alzheimer's disease (AD), can induce mitochondrial oxidative stress and impair mitochondrial function besides causing mitochondrial DNA (mtDNA) damage. Aβ42O also regulate the proliferative and differentiative properties of stem cells.

Objective: We aimed to study whether Aβ42O-induced mtDNA damage is involved in the regulation of stem cell differentiation.
