Monitoring the genetic diversity in holothurian populations from the Italian coasts with mitochondrial DNA sequences.

Sea cucumbers are deposit feeding members of marine benthic communities. The over-exploitation of sea cucumber natural stocks, especially in the Mediterranean basin, is having negative impacts on the marine ecosystem. This concerns had led the Italian government to take legal actions to preserve these important marine resources.

The Role of Adiponectin and Leptin in Fibro-Calcific Aortic Valve Disease: A Systematic Review and Meta-Analysis.

Background: Fibro-calcific aortic valve disease (FCAVD) is a progressive disorder characterized by the thickening and calcification of the aortic valve, eventually leading to aortic stenosis. Adiponectin and leptin, known for their anti-inflammatory and proinflammatory properties, respectively, have been implicated in cardiovascular diseases, but their associations with FCAVD are controversial. This meta-analysis aims to evaluate the relationships between adiponectin and leptin levels and FCAVD, particularly in patients with severe aortic stenosis (AS).

A comprehensive atlas of nuclear sequences of mitochondrial origin (NUMT) inserted into the pig genome.

Background: The integration of nuclear mitochondrial DNA (mtDNA) into the mammalian genomes is an ongoing, yet rare evolutionary process that produces nuclear sequences of mitochondrial origin (NUMT). In this study, we identified and analysed NUMT inserted into the pig (Sus scrofa) genome and in the genomes of a few other Suinae species. First, we constructed a comparative distribution map of NUMT in the Sscrofa11.

Biologics in T2 Severe Asthma: Unveiling Different Effectiveness by Real-World Indirect Comparison.

: Indirect comparison among biologics in severe asthma (SA) is a challenging but desirable goal for clinicians in real life.

Upregulation of Notch Signaling and Cell-Differentiation Inhibitory Transcription Factors in Stable Chronic Obstructive Pulmonary Disease Patients.

Notch signaling is involved in the prevention of cell differentiation and cell fate in various organs, including the lungs. We aimed to determine the transcriptomic and protein expression of Notch receptors, their ligands, and related transcription factors in stable COPD. The expression and localization of Notch receptors, their ligands, and related transcription factors were measured in bronchial biopsies of individuals with stable mild/moderate (MCOPD) (n = 18) or severe/very severe (SCOPD) (n = 16) COPD, control smokers (CSs) (n = 13), and control nonsmokers (CNSs) (n = 11), and in the lung parenchyma of those with MCOPD (n = 13), CSs (n = 10), and CNSs (n = 10) using immunohistochemistry, ELISA tests, and transcriptome analyses.

Investigation of Gene Variants across More Than 60 Pig Breeds and Populations and Other Species Using Whole-Genome Sequencing Datasets.

Polymorphisms in the human gene determine the major blood classification system based on the three well-known forms: ; ; and . In pigs that carry only two main alleles in this gene ( and ), we still need to obtain a more comprehensive distribution of variants, which could also impact its function. In this study, we mined more than 500 whole-genome sequencing datasets to obtain information on the gene in different species, pig breeds, and populations and provide (i) a comprehensive distribution of the and alleles, (ii) evolutionary relationships of gene sequences across species, and (iii) an exploratory evaluation of the effect of the different gene variants on production traits and blood-related parameters in Italian Large White pigs.

Identification of population-informative markers from high-density genotyping data through combined feature selection and machine learning algorithms: Application to European autochthonous and cosmopolitan pig breeds.

Large genotyping datasets, obtained from high-density single nucleotide polymorphism (SNP) arrays, developed for different livestock species, can be used to describe and differentiate breeds or populations. To identify the most discriminating genetic markers among thousands of genotyped SNPs, a few statistical approaches have been proposed. In this study, we applied the Boruta algorithm, a wrapper of the machine learning random forest algorithm, on a database of 23 European pig breeds (20 autochthonous and three cosmopolitan breeds) genotyped with a 70k SNP chip, to pre-select informative SNPs.

Genome-wide association studies for diarrhoea outcomes identified genomic regions affecting resistance to a severe enteropathy in suckling rabbits.

Selection and breeding strategies to improve resistance to enteropathies are essential to reaching the sustainability of the rabbit production systems. However, disease heterogeneity (having only as major visible symptom diarrhoea) and low disease heritability are two barriers for the implementation of these strategies. Diarrhoea condition can affect rabbits at different life stages, starting from the suckling period, with large negative economic impacts.

Fast and sensitive method for the diagnosis and follow-up of anticoagulant rodenticides poisoning in animal whole blood.

Rodent control strategies are primarily based on the use of anticoagulant rodenticides (ARs), making them widely used worldwide. However, due to their high toxicity and availability, ARs are among the leading causes of animal poisoning in Europe. They are the primary agents involved in intoxication in cats and the second in dogs.

Comparative targeted metabolomic profiles of porcine plasma and serum.

Metabolomics has been used to characterise many biological matrices and obtain detailed pictures of biological systems based on many metabolites. Plasma and serum are two blood-derived biofluids commonly used to assess and monitor the organismal metabolism and obtain information on the physiological and health conditions of an animal. Plasma is the supernatant that is separated from the cellular components after centrifugation of the blood that is first added with an anticoagulant.

Signatures of Admixture and Genetic Uniqueness in the Autochthonous Greek Black Pig Breed Deduced from Gene Polymorphisms Affecting Domestication-Derived Traits.

The Greek Black Pig (or Greek Pig) is the only recognized autochthonous pig breed raised in Greece, usually in extensive or semi-extensive production systems. According to its name, the characteristic breed coat color is solid black. In this study, with the aim to start a systematic genetic characterization of the Greek Black Pig breed, we investigated polymorphisms in major genes well known to affect exterior and production traits (, , , and ) and compared these data with population genetic information available in other Mediterranean and Western Balkan pig breeds and wild boars.

Reliability of Total Serum IgE Levels to Define Type 2 High and Low Asthma Phenotypes.

High total IgE levels are weak predictors of T2 and have been reported in nonallergic asthma. Therefore, the role of total serum IgE (IgE) in the T2 phenotype is still debated. Objective: This study investigated the reliability of stratifying asthmatics into IgE and IgE within the T2 and T2 phenotypes.

Population genomic structures and signatures of selection define the genetic uniqueness of several fancy and meat rabbit breeds.

Following the recent domestication process of the European rabbit (Oryctolagus cuniculus), many different breeds and lines, distinguished primarily by exterior traits such as coat colour, fur structure and body size and shape, have been constituted. In this study, we genotyped, with a high-density single-nucleotide polymorphism panel, a total of 645 rabbits from 10 fancy breeds (Belgian Hare, Champagne d'Argent, Checkered Giant, Coloured Dwarf, Dwarf Lop, Ermine, Giant Grey, Giant White, Rex and Rhinelander) and three meat breeds (Italian White, Italian Spotted and Italian Silver). ADMIXTURE analysis indicated that breeds with similar phenotypic traits (e.

Bacterial load and related innate immune response in the bronchi of rapid decliners with chronic obstructive pulmonary disease.

Objective: To determine the microbiota associated to markers of innate immune host response in COPD patients with rapid lung functional decline.

Phenotype overlap in the natural history of asthma.

The heterogeneity of asthma makes it challenging to unravel the pathophysiologic mechanisms of the disease. Despite the wealth of research identifying diverse phenotypes, many gaps still remain in our knowledge of the disease's complexity. A crucial aspect is the impact of airborne factors over a lifetime, which often results in a complex overlap of phenotypes associated with type 2 (T2), non-T2 and mixed inflammation.

Whole Genome Sequencing Provides Information on the Genomic Architecture and Diversity of Cultivated Gilthead Seabream () Broodstock Nuclei.

The gilthead seabream () is a species of relevance for the Mediterranean aquaculture industry. Despite the advancement of genetic tools for the species, breeding programs still do not often include genomics. In this study, we designed a genomic strategy to identify signatures of selection and genomic regions of high differentiation among populations of farmed fish stocks.

Analysis of Metaldehyde in Animal Whole Blood and Serum by Gas Chromatography-Mass Spectrometry.

Metaldehyde, a widely used molluscicide, is the third cause of intoxication by pesticides in domestic animals in Europe. Most mammalian species are susceptible, and its exposure may lead to death within a few hours. While metaldehyde intoxication diagnosis is in most cases presumptive, based on the symptomatology or from "postmortem" analysis, few analytical methods are currently available for live animals.

Long-Term Safety of Antifibrotic Drugs in IPF: A Real-World Experience.

Pirfenidone and nintedanib are the only two drugs approved for the treatment of idiopathic pulmonary fibrosis (IPF). Both proved to be safe and well-tolerated in clinical trials, but real-world data and direct comparisons are scarce. This real-life study explored the safety profile of pirfenidone and nintedanib with a prolonged follow-up.

Blood-based gene expression as non-lethal tool for inferring salinity-habitat history of European eel (Anguilla anguilla).

The European eel is a facultative catadromous species, meaning that it can skip the freshwater phase or move between marine and freshwater habitats during its continental life stage. Otolith microchemistry, used to determine the habitat use of eel or its salinity history, requires the sacrifice of animals. In this context, blood-based gene expression may represent a non-lethal alternative.

Exhaled nitric oxide in asthma: from diagnosis to management.

Purpose Of Review: Exhaled nitric oxide (FENO) is a noninvasive marker of eosinophilic airway inflammation, therefore, highly informative in asthma. Although FENO measurement is a potentially accessible tool to many physicians, recommendations regarding its clinical utility in diagnosing or tailoring treatment have not reached the expected diffusion. More recently FENO emerged as a biomarker for type-2 asthma phenotyping and a predictor of response to biologics.
