High-throughput seed quality analysis in faba bean: leveraging Near-InfraRed spectroscopy (NIRS) data and statistical methods.

Near-infrared spectroscopy (NIRS) provides a high-throughput phenotyping technique to assist breeding for improved faba bean seed quality. We combined chemical analysis of protein, oil content (and composition) with NIRS through chemometrics, employing Partial Least Squares (PLS), Elastic Net (EN), Memory-based Learning (MBL), and Bayes B (BB) as prediction models. Protein was the most reliably predicted trait (R = 0.

The challenge of breeding for reduced off-flavor in faba bean ingredients.

The growing interest in plant protein sources, such as pulses, is driven by the necessity for sustainable food production and climate change mitigation strategies. Faba bean (.) is a promising protein crop for temperate climates, owing to its remarkable yield potential (up to 8 tonnes ha in favourable growing conditions) and high protein content (~29% dry matter basis).

A genome wide association study to dissect the genetic architecture of agronomic traits in Andean lupin ().

Establishing as a protein and oil crop requires improved varieties adapted to EU climates. The genetic regulation of strategic breeding traits, including plant architecture, growing cycle length and yield, is unknown. This study aimed to identify associations between 16 669 single nucleotide polymorphisms (SNPs) and 9 agronomic traits on a panel of 223 accessions, grown in four environments, by applying a genome wide association study (GWAS).

Interleukin 1β Blockade Reduces Intestinal Inflammation in a Murine Model of Tumor Necrosis Factor-Independent Ulcerative Colitis.

Background & Aims: Inflammatory bowel diseases are multifactorial diseases commonly treated with either immunomodulatory drugs or anti-tumor necrosis factor (TNF). Currently, failure to respond to anti-TNF therapy (assessed no earlier than 8-12 weeks after starting treatment) occurs in 20%-40% of patients enrolled in clinical trials and in 10%-20% in clinical practice. Murine models of inflammatory bowel disease provide important tools to better understand disease mechanism(s).

Polyphenol Enriched Diet Administration During Pregnancy and Lactation Prevents Dysbiosis in Ulcerative Colitis Predisposed Littermates.

Neonatal colonization of the gastrointestinal tract depends on mother microbiome, thus mother microbiota dysbiosis is transmitted to the offspring during the delivery and shaped by breastmilk characteristics. Here we used a murine model of UC predisposition (Winnie) to evaluate the effects of maternal diet during pregnancy and lactation. Using heterozygous breeders, we obtained both Winnie and C57BL/6 littermates from the same mother and compared their microbiota at weaning and adult age, using a diet enriched with 1% tomato fruit of a line - named Bronze - highly enriched in bioactive polyphenols, or Control tomato.

Microbes: Food for the Future.

Current projections estimate that in 2050 about 10 billion people will inhabit the earth and food production will need to increase by more than 60%. Food security will therefore represent a matter of global concern not easily tackled with current agriculture practices and curbed by the increasing scarcity of natural resources and climate change. Disrupting technologies are urgently needed to improve the efficiency of the food production system and to reduce the negative externalities of agriculture (soil erosion, desertification, air pollution, water and soil contamination, biodiversity loss, etc.

Genomic Surveillance of Circulating SARS-CoV-2 in South East Italy: A One-Year Retrospective Genetic Study.

In order to provide insights into the evolutionary and epidemiological viral dynamics during the current COVID-19 pandemic in South Eastern Italy, a total of 298 genomes of SARS-CoV-2 strains collected in the Apulia and Basilicata regions, between March 2020 and January 2021, were sequenced. The genomic analysis performed on the draft genomes allowed us to assign the genetic clades and lineages of belonging to each sample and provide an overview of the main circulating viral variants. Our data showed the spread in Apulia and Basilicata of SARS-CoV-2 variants which have emerged during the second wave of infections and are being currently monitored worldwide for their increased transmission rate and their possible impact on vaccines and therapies.

Nonalcoholic Fatty Liver Disease: Focus on New Biomarkers and Lifestyle Interventions.

Nonalcoholic fatty liver disease (NAFLD) is considered a hepatic manifestation of metabolic syndrome, characterized from pathological changes in lipid and carbohydrate metabolism. Its main characteristics are excessive lipid accumulation and oxidative stress, which create a lipotoxic environment in hepatocytes leading to liver injury. Recently, many studies have focused on the identification of the genetic and epigenetic modifications that also contribute to NAFLD pathogenesis and their prognostic implications.

Stone heart: An unusual case of heart failure with preserved ejection fraction due to massive myocardial calcification.

We report an unusual case of heart failure due to massive myocardial calcification related to a rare combination of idiopathic mitral annular calcification, myocardial calcification of the left ventricular septum and the inferior wall without other predisposing factors, such as previous myocardial infarction, ventricular aneurysms, myocarditis, rheumatic heart disease, tuberculosis, chronic renal failure, or systemic metabolic disease (sarcoidosis or primary hyperoxaluria). The related restrictive pattern of diastolic filling of the left ventricle could explain this unusual case of heart failure with preserved ejection fraction. < The prevalence of heart failure with preserved ejection fraction has increased with an increasing prevalence of risk factors.

Dysbiosis Triggers ACF Development in Genetically Predisposed Subjects.

Background: Colorectal cancer (CRC) is the third most common cancer worldwide, characterized by a multifactorial etiology including genetics, lifestyle, and environmental factors including microbiota composition. To address the role of microbial modulation in CRC, we used our recently established mouse model (the Winnie-APC) combining inflammation and genetics.

Methods: Gut microbiota profiling was performed on 8-week-old Winnie-APC mice and their littermates by 16S rDNA gene amplicon sequencing.

miR-369-3p modulates inducible nitric oxide synthase and is involved in regulation of chronic inflammatory response.

Dendritic cells are the most important antigen-presenting cells that link the innate and acquired immune system. In our previous study, we identified that the upregulation of miR-369-3p suppresses the LPS-induced inflammatory response, reducing C/EBP-β, TNFα and IL-6 production. With the aim of gaining further insight into the biological function of miR-369-3p during acute inflammatory response, in the present study we identified novel gene targets of miR-369-3p and demonstrated the suppressive ability of these genes on the inflammatory dendritic cells.

Evaluation of Antibiotic Resistance of Strains Isolated in Bari, Southern Italy, in 2017-2018 by Phenotypic and Genotyping Methods.

antibiotic resistance is a constantly evolving process and local surveillance is warranted to guide clinicians in the choice of therapy. Antibiotic susceptibility testing was performed by E-test on 92 strains, and resistance to clarithromycin and levofloxacin was also evaluated using a commercially available genotyping method. In naïve patients the resistance to clarithromycin, levofloxacin, and metronidazole was 37.

Iron Overload Mimicking Conditions Skews Bone Marrow Dendritic Cells Differentiation into MHCIICD11cCD11bF4/80 Cells.

Iron overload is an undesired effect of frequent blood transfusions or genetic diseases. Myelodysplastic syndrome (MDS) patients become transfusion dependent, but due to the combination of ineffective haematopoiesis and repeated blood transfusions they are often subject to iron overload. In this study, we demonstrate that iron-overload mimicking condition alters bone marrow progenitor differentiation towards dendritic cells (DCs).

A Specific Mutation in Muc2 Determines Early Dysbiosis in Colitis-Prone Winnie Mice.

Background: Inflammatory bowel disease (IBD), including Crohn disease (CD) and ulcerative colitis (UC), is a multifactorial disorder characterized by chronic inflammation and altered gut barrier function. Dysbiosis, a condition defined by dysregulation of the gut microbiome, has been reported in patients with IBD and in experimental models of colitis. Although several factors have been implicated in directly affecting gut microbial composition, the genetic determinants impacting intestinal dysbiosis in IBD remain relatively unknown.

Quercetin Exposure Suppresses the Inflammatory Pathway in Intestinal Organoids from Winnie Mice.

Inflammatory bowel diseases (IBDs) are chronic and relapsing immune disorders that result, or possibly originate, from epithelial barrier defects. Intestinal organoids are a new reliable tool to investigate epithelial response in models of chronic inflammation. We produced organoids from the ulcerative colitis murine model Winnie to explore if the chronic inflammatory features observed in the parental intestine were preserved by the organoids.

Cardiac Arrhythmias and Acute Cerebrovascular Events: A Case of QT Prolongation and Torsades de Pointes Early After Right Insular Stroke.

Stroke involving some areas of the cerebral hemisphere, such as insula, amygdala, and lateral hypothalamus, may cause changes in autonomic control of cardiac function. A 58-year-old woman presented to the emergency department for acute onset of left facial-brachial-crural hemiparesis and dysarthria. A brain CT scan showed subacute ischemic lesion with hemorrhagic infarction in right insular-rolandic cortex.

Syncope in a patient with acute pulmonary embolism and Brugada Type-2 ECG pattern: Brugada phenocopy or Brugada syndrome?

Brugada phenocopies are clinical entities characterized by electrocardiographic patterns that are identical to true Brugada syndrome, but are elicited by a number of clinical circumstances. ECG normalizes upon resolution of underlying condition, family history of arrhythmic syncope or ventricular arrhythmias is strictly absent and provocative tests with sodium channel blockers have to be negative. We describe herein the case of type-2 ECG Brugada pattern in a patient with acute pulmonary embolism presenting with recurrent syncope but negative provocative test with sodium channel blockers.

A case report of esophageal actinomycosis in an immunocompetent patient and review of the literature.

Actinomycosis is a rare, chronic and slowly progressive granulomatous disease caused by Actinomyces spp., a Gram-positive anaerobic bacterium that rarely affects the esophagus. Although this infection is uncommon, it has been reported in both immunocompromised and immunocompetent individuals.

A Bronze-Tomato Enriched Diet Affects the Intestinal Microbiome under Homeostatic and Inflammatory Conditions.

Inflammatory bowel diseases (IBD) are debilitating chronic inflammatory disorders that develop as a result of a defective immune response toward intestinal bacteria. Intestinal dysbiosis is associated with the onset of IBD and has been reported to persist even in patients in deep remission. We investigated the possibility of a dietary-induced switch to the gut microbiota composition using Winnie mice as a model of spontaneous ulcerative colitis and chow enriched with 1% Bronze tomato.
