Insights into the genomic and phenotypic characteristics of spp. strains isolated from biofilms in broiler farms.

The characterization of surface microbiota living in biofilms within livestock buildings has been relatively unexplored, despite its potential impact on animal health. To enhance our understanding of these microbial communities, we characterized 11 spore-forming strains isolated from two commercial broiler chicken farms. Sequencing of the strains revealed them to belong to three species , , and .

Effect of Bacillus toyonensis BCT-7112 supplementation on growth performance, intestinal morphology, immune-related gene expression, and gut microbiome in Barbary ducks.

This study aimed to investigate the effect of Bacillus toyonensis BCT-7112 supplementation on growth performance, intestinal morphology, immune-related gene expression, and the cecal microbiota of meat ducks. A total of 150 one-day-old male Barbary ducks were divided into 3 groups with 5 replicates (n = 10 ducks per replicate) by completely randomized design and offered diets supplemented with the commercial product Toyocerin (containing 1 × 10B. toyonensis BCT-7112 viable spores/g product) at the levels of 0, 500, or 1,000 mg/kg (0, 500, or 1,000 ppm), respectively, for 8 wk.

Probiotic, Paraprobiotic, and Hydrolyzed Yeast Mixture Supplementation Has Comparable Effects to Zinc Oxide in Improving Growth Performance and Ameliorating Post-weaning Diarrhea in Weaned Piglets.

A total of 150 21-day-old weaned piglets [(Yorkshire × Landrace) × Duroc] were randomly assigned to 3 groups (CON, TRT1, TRT2) to evaluate the effects of dietary supplementation of probiotic, paraprobiotic, and hydrolyzed yeast mixture (PPY) on growth performance, nutrient digestibility, fecal bacterial counts, fecal calprotectin contents, and diarrhea rate in a 42-day experiment (phase 1: days 1-14; phase 2: days 15-42). There were 10 replicate pens per treatment with 5 pigs per pen (three gilts and two barrows). Pigs in CON were only provided with a basal diet.

Differences in L-arginine metabolism and asthma morbidity among asthma patients with and without obstructive sleep apnea.

Background: Imbalance in L-arginine and nitric oxide (NO) metabolism has been implicated in the pathophysiology of asthma and obstructive sleep apnea (OSA), and both diseases impact the other's morbidity. We sought to determine whether L-arginine/NO metabolism differs between adults with asthma with or without comorbid OSA, and its association with asthma morbidity.

Methods: This is a cross-sectional study of 322 adults with asthma recruited in Denver, CO and New York City, NY.

Machine learning for the automatic assessment of aortic rotational flow and wall shear stress from 4D flow cardiac magnetic resonance imaging.

Objective: Three-dimensional (3D) time-resolved phase-contrast cardiac magnetic resonance (4D flow CMR) allows for unparalleled quantification of blood velocity. Despite established potential in aortic diseases, the analysis is time-consuming and requires expert knowledge, hindering clinical application. The present research aimed to develop and test a fully automatic machine learning-based pipeline for aortic 4D flow CMR analysis.

Histopathologic Analysis of Surgically Resected Lungs of Patients with Non-tuberculous Mycobacterial Lung Disease: a Retrospective and Hypothesis-generating Study.

Non-tuberculous mycobacterial lung disease (NTM-LD) is most commonly due to species within the complex (MAC) and complex (MAbC). Surgical lung resection, typically a lobectomy or segmentectomy, is occasionally undertaken for individuals with recalcitrant but localized NTM-LD. Since the growth characteristics of MAC (slow growers) and MAbC (rapid growers) as well as their drug susceptibility patterns are significantly different, the objective of this study is to characterize and compare the histopathologic features of the resected lungs due to these two major NTM groups.

Medicalisation and participation in legal capacity determinations in Chile.

This paper provides an examination of the process used by ordinary courts in Chile when making legal capacity determinations. It provides an up-to-date account of various aspects of law and procedure related to legal capacity in this jurisdiction. Also, by drawing on semi-structured interviews with judges, this paper examines judicial understandings of legal capacity decision-making focusing on problems related to the medicalisation of mental disability and the participation of persons with disabilities in legal capacity procedures.

The -Group Bacterium as a Safe Probiotic Solution for Aquaculture.

Phaeobacter inhibens has been assessed as a probiotic bacterium for application in aquaculture. Studies addressing the efficacy and safety indicate that maintains its antagonistic activity against pathogenic vibrios in aquaculture live cultures (live feed and fish egg/larvae) while having no or a positive effect on the host organisms and a minor impact on the host microbiomes. While produces antibacterial and algicidal compounds, no study has so far found a virulent phenotype of cells against higher organisms.

A review of unmanned vehicles for the detection and monitoring of marine fauna.

Recent technology developments have turned present-day unmanned systems into realistic alternatives to traditional marine animal survey methods. Benefits include longer survey durations, improved mission safety, mission repeatability, and reduced operational costs. We review the present status of unmanned vehicles suitable for marine animal monitoring conducted in relation to industrial offshore activities, highlighting which systems are suitable for three main monitoring types: population, mitigation, and focal animal monitoring.

Design and implementation of a control structure for quality products in a crude oil atmospheric distillation column.

In recent years, interest for petrochemical processes has been increasing, especially in refinement area. However, the high variability in the dynamic characteristics present in the atmospheric distillation column poses a challenge to obtain quality products. To improve distillates quality in spite of the changes in the input crude oil composition, this paper details a new design of a control strategy in a conventional crude oil distillation plant defined using formal interaction analysis tools.

The Identification of Intrinsic Chloramphenicol and Tetracycline Resistance Genes in Members of the Group ().

strain BCT-7112 (NCIMB 14858) has been widely used as an additive in animal nutrition for more than 30 years without reports of adverse toxigenic effects. However, this strain is resistant to chloramphenicol and tetracycline and it is generally considered inadvisable to introduce into the food chain resistance determinants capable of being transferred to other bacterial strains, thereby adding to the pool of such determinants in the gastro-enteric systems of livestock species. We therefore characterized the resistance phenotypes of this strain and its close relatives to determine whether they were of recent origin, and therefore likely to be transmissible.

Additive value of non-contrast MRA in the preoperative evaluation of potential liver donors.

The purpose of this study is to compare diagnostic quality, inter-observer variability and agreement of non-contrast enhanced MRA (NC-MRA) with contrast-enhanced MRA (CE-MRA) in the evaluation of hepatic arterial anatomy. 20 potential liver donors were included in this retrospective study. NC-MRA, CE-MRA and combined data sets were randomized and reviewed by two readers.

Historical perspective: eponyms of vascular radiology.

Eponyms are ubiquitous throughout the medical literature, especially the radiology lexicon. In particular, vascular radiology is replete with dozens of eponyms named after pathologic and anatomic features and various medical devices. Several disease processes are known exclusively by their eponyms or by both their eponyms and their descriptive names.
