PURPOSE: Delta-5-desaturase (fatty acid desaturase-1, FADS1) and delta-6 desaturase (fatty acid desaturase-2, FADS2), rate-limiting enzymes in the biosynthesis of long-chain polyunsaturated fatty acids, may be associated with the risk of metabolic syndrome (MetS). We investigated how FADS1 rs174547 and FADS2 rs2845573 variants modify the prevalence of MetS and whether the risk is modulated by interactions with dietary fat. METHODS: Genetic, anthropometric, biochemical, and dietary data were collected from the Ansan/Ansung (8842 adults) and City-Rural (5512 adults) cohorts in Korea...

PURPOSE: In obesity and diabetes the liver is highly susceptible to abnormal uptake and storage of fat. In certain individuals hepatic steatosis predisposes to the development of non-alcoholic steatohepatitis (NASH), a disease marked by hepatic inflammation and fibrosis. Although the precise pathophysiology of NASH is unknown, it is believed that the gut microbiota-liver axis influences the development of this disease. With few treatment strategies available for NASH, exploration of gut microbiota-targeted interventions is warranted...

OBJECTIVES: Development of non-Hodgkin's lymphoma (NHL) is the major adverse outcome of Sjögren's syndrome (SS) affecting both morbidity and mortality. Preliminary evidence suggested that, although not deregulated compared with sicca controls, miR200b-5p levels are decreased in the minor salivary glands (MSGs) of SS patients with NHL. The aim of the current study was to evaluate the MSG expression of miR200b-5p in SS-associated NHLs and its potential predictive value for the identification of patients with SS susceptible to develop NHL...

Cumulating epidemiological studies demonstrated that environmental exposure to endocrine disrupting chemicals (EDCs) during the early stages of fetal development is associated with the increase in disease susceptibility in later life. The fetal developmental plasticity is considered as a protective mechanism against an undesirable prenatal environment. Dioxin is one of the environmental contaminants and is considered a diabetogenic factor. Experimental animal and human epidemiological studies have revealed that dioxin exposure was associated with insulin resistance and altered beta cell function...

Arsenic (As) is a ubiquitous environmental toxin and robust inducer of oxidative stress (OxS). Copper (Cu) is an essential microelement, which participates in OxS as a cofactor for certain enzymes, with narrow optimal range between essential and toxic concentrations. However, their effects are rarely studied in chicken skeletal muscles, which have soaring per capita consumption andare susceptible to oxidative damage. In the present study, we demonstrated that the administration of copper sulfate (300 mg kg-1 ) or arsenite (30 mg kg-1 ) individually or their co-administration leads to varying degrees of OxS in the skeletal muscles of chickens...

The survival of aquatic biota in stream ecosystems depends on both water quantity and quality, and is particularly susceptible to degraded water quality in regulated rivers. Maintenance of environmental flows (e-flows) for aquatic biota with optimum water quantity and quality is essential for sustainable ecosystem services, especially in developing regions with insufficient stream monitoring of hydrology, water quality and aquatic biota. Few e-flow methods are available that closely link aquatic biota tolerances to pollutant concentrations in a simple and practical manner...

The primary objective of this randomized controlled trial was to determine whether anti-IL-10 egg yolk antibodies fed upon arrival to a calf ranch would lower the prevalence of Cryptosporidium parvum shedding in naturally challenged preweaned dairy calves. The secondary objectives included measuring the effect of anti-IL-10 antibodies on calf health, performance, and shedding of less common diarrheal pathogens. A total of 133 calves, enrolled at 24 to 72 h of age, received a daily dose of 0.96 g of egg yolk powder with anti-IL-10 antibodies (MAB, n = 71) or without anti-IL-10 antibodies (MEP, n = 62) split between 2 feedings for the first 11 d on feed at a calf ranch...

BACKGROUND: Pseudomonas is a group of medically important species that inhabit a wide range of niches, including hospital environments. Controversies have emerged about the possible link between improper use of disinfectants and the emergence of antibiotic resistance in bacteria. The aim of this study was to assess the effect of exposure of antibiotic-susceptible Pseudomonas isolates to sub-inhibitory concentrations of 2 disinfectants-didecyldimonium chloride and sodium hypochlorite-on their antibiotic susceptibility patterns...

Although ankylosing spondylitis (AS) is a common, highly heritable arthropathy, the precise genetic mechanism underlying the disease remains elusive. Here, we investigate the disease-causing mutations in a large AS family with distinguished complexity, consisting of 23 patients covering four generations and exhibiting a mixed HLA-B27 (+) and (-) status. Linkage analysis with 32 members using three methods and whole-exome sequencing analysis with three HLA-B27 (+) patients, one HLA-B27 (-) patient, and one healthy individual did not identify a mutation common to all of the patients, strongly suggesting the existence of genetic heterogeneity in this large pedigree...

BACKGROUND: There is a widespread belief that Asians are more susceptible to hemorrhagic transformation (HT) after receiving recombinant tissue-type plasminogen activator (rt-PA) for acute ischemic stroke (AIS). However, this has not been examined in clinical practice. This study aims to compare the incidence of symptomatic hemorrhagic transformation (SHT) among thrombolysis-treated AIS patients in China and in the United States. METHODS: We compared 212 consecutive patients receiving thrombolysis within 4...

European rabbits (Oryctolagus cuniculus) are severely affected by rabbit haemorrhagic disease (RHD). Caused by a lagovirus, the disease leads to losses in the rabbit industry and has implications for wildlife conservation. Past RHD outbreaks have been caused by GI.1/RHDV genotype viruses. A new virus belonging to the GI.2/RHDV2/b genotype emerged in 2010, quickly spreading and replacing the former in several countries; however, limited data are available on its pathogenicity and epidemiological factors. The present work extends these issues and evaluates cross-protection between both genotypes...

Since its arrival in the Caucasus and Russia in 2007, African swine fever virus (ASFV) has spread widely and has now affected the EU countries of Estonia, Latvia, Lithuania, Poland and, more recently, the Czech Republic and Romania. The ever-increasing evidence of seropositive wild boar in certain areas suggests that some animals may be surviving for some time or could even be recovering from the disease. This could be due to acquired immunity after the primary infection and/or the presence of related viruses of reduced virulence...

Extended-spectrum β-lactamase (ESBL)-producing Escherichia coli isolates have been increasingly reported in different reservoirs. The aims of this study were to investigate the presence of ESBL-producing E. coli in fresh vegetables and to characterise their ESBL gene-carrying plasmids. Among the 245 samples from vegetables investigated during 2011-2013, seven putative ESBL-producing E. coli (salad n = 2, sprouts n = 5) were found. They were subjected to ESBL phenotypic confirmatory tests, detection/sequencing of ESBL genes, antimicrobial susceptibility testing (AST), phylotyping, XbaI-macrorestriction analysis, multilocus sequence typing and transformation...

Vesicular stomatitis virus (VSV) can cause serious vesicular lesions in pigs, and the matrix (M) protein is its predominant virulence factor. Dendritic cells (DCs) act as the bridge between innate and adaptive immune responses. However, the susceptibility of porcine DCs to VSV infection and the role of M protein in modulating the function of infected DCs are still poorly defined. Thus, this study aimed to determine the ability of virulent wild-type VSV(wtVSV) and two attenuated M protein variants (VSVΔM51 and VSVMT ) to induce maturation of porcine monocyte-derived DCs (MoDCs) in vitro...

Mycoplasma hyopneumoniae (M. hyopneumoniae) is the primary causative agent of enzootic pneumonia (EP), one of the most economically important infectious disease for the swine industry worldwide. M. hyopneumoniae transmission occurs mainly by direct contact (nose-to-nose) between infected to susceptible pigs as well as from infected dams to their offspring (sow-to-piglet). Since disease severity has been correlated with M. hyopneumoniae prevalence at weaning in some studies, and gilts are considered the main bacterial shedders, an effective gilt acclimation program should help controlling M...
