Selenium (Se) deficiency and poor plasma Se levels can cause cardiovascular diseases by decreasing selenoprotein levels. Neutrophil extracellular traps (NETs) may be the vicious cycle center of inflammation in vasculitis. Here, we show that Se deficiency induced arteritis mainly by reducing selenoprotein S (SelS), and promoted the progression of arteritis by regulating the recruitment of neutrophils and NET formation. Silencing SelS induced chicken arterial endothelial cells (PAECs) to secrete cytokines, and activated neutrophils to promote NET formation. Conversely, scavenging DNA-NETs promoted cytokine secretion in PAECs. The NET formation regulated by siSelS was dependent on a reactive oxygen species (ROS) burst. We also found that the PPAR pathway was a major mediator of NET formation induced by Se-deficient arteritis. Overall, our results reveal how Se deficiency regulates NET formation in the progression of arteritis and support silencing-SelS worsens arteritis.Salmonella enterica is a major cause of foodborne diseases, and is also an important pathogenic bacterium in poultry industry. Whole genome sequencing (WGS) has become a crucial molecular typing technology used for the surveillance of the pathogenic bacteria. In the present study, we adopted WGS for tracking transmission of S. enterica in the production chain of broiler chickens. A total of 74 S. enterica strains were isolated from the different steps of breeding and slaughtering in a large production enterprise in Sichuan Province, China. The isolation rate of Salmonella was the highest in procedure of defeathering (50.0%) and evisceration (36.7%). Serotype identification showed that 74 Salmonella isolates included 7 serotypes, among which Mbandaka accounted for the highest proportions (35.1%). WGS revealed that 74 strains belonged to 7 different sequence types (STs), as well as 7 different ribosomal STs and 35 core genome STs. cgMLST-based Minimum Spanning Trees and phylogenetic tree based on the SNPs indicated that three serotypes, Mbandaka, Indiana and Kentucky, could be clonally transmitted between broiler farm and slaughterhouse. Heterogeneous resistant phenotypes and genotypes were found in two serotypes, Indiana and Kentucky. Our study indicated WGS in an accurate tool for molecular typing of S. enterica. Routine surveillance of S. enterica in the production chain of broiler chickens is needed.
  To detect modifiable factors and target populations associated with uncontrolled type 2 diabetes in primary care.
 
  Retrospective cross-sectional descriptive study.
 
  Health center of Barranco Grande, Tenerife.
 
  Random selection of patients with DM2 attended by 12 family doctors and 12 nurses.
 
  In addition to the control of DM2, sociodemographic, clinical data, lifestyle and follow-up of preventive and therapeutic measures were obtained. After bivariate analysis, a multilevel multivariate model was adjusted by taking the quota of patients assisted by each physician as a second-level mixed-effect variable and the rest as first-level variables.
 
  587 patients were recruited (46.5% female), treated with 1.9-1.1 antidiabetic drugs, with 4.1% therapeutic non-compliance, and suffering 13.8% therapeutic inertia. 23.7% showed poor DM2 control, being significantly worse (p<0.05) in male sex, age <65 years, evolution DM2 -5 years, work-active, upper-middle studies, inadequate diet, metabolic syndrome, ratio TG/HDL-3, complications of DM2, Charlson index<5, nursing visits <3/year, without ECG in the last year, and more drugs prescribed for DM2. The doctor-nurse quota was associated with poor control with an intraclass coefficient of 0.01.
 
  Men under 65 years of age with DM2 evolution longer than 5 years are a target population to intensify interventions. Therapeutic non-compliance, inadequate diet, lack of adherence protocols and ratio TG/HDL>3 are the main modifiable factors on which to intervene. The association of the doctor-nurse quota with the control of DM2 is weak, probably due to adequate follow-up of preventive programs.
 3 are the main modifiable factors on which to intervene. The association of the doctor-nurse quota with the control of DM2 is weak, probably due to adequate follow-up of preventive programs.Magnetic Resonance Elastography (MRE) is a non-invasive imaging technique which involves motion-encoding MRI for the estimation of the shear viscoelastic properties of soft tissues through the study of shear wave propagation. The technique has been found informative for disease diagnosis, as well as for monitoring of the effects of therapies. The development of MRE and its validation have been supported by the use of tissue-mimicking phantoms. In this paper we present our new MRE protocol using a low magnetic field tabletop MRI device at 0.5 T and sinusoidal uniaxial excitation in a geometrical focusing condition. Results obtained for gelatin are compared to those previously obtained using high magnetic field MRE at 11.7 T.  https://www.selleckchem.com/products/dir-cy7-dic18.html  A multi-frequency investigation is also provided via a comparison of commonly used rheological models Maxwell, Springpot, Voigt, Zener, Jeffrey, fractional Voigt and fractional Zener. Complex shear modulus values were comparable when processed from images acquired with the tabletop low field scanner and the high field scanner. This study serves as a validation of the presented tabletop MRE protocol and paves the way for MRE experiments on ex-vivo tissue samples in both normal and pathological conditions.In this report, blue fluorescent zinc selenide quantum dots (ZnSe QDs) were synthesized using 3-mercaptopropionic acid through a direct aqueous route at a lower temperature of 70 °C. The photoluminescence (PL) characteristics of ZnSe QDs have been employed to recognize nitroaromatic compounds, i.e., traces of 2,4,6-TNP (picric acid) in water. The sensing of nitroaromatic compounds was performed via fluorescence techniques. The PL band of ZnSe QDs observed at 490 nm is selectively quenched with an increasing concentration of picric acid in DI water and river water. For the proposed sensing probe, the Stern-Volmer (S-V) plot shows linearity over the range of 2.0 µM-0.25 mM with the detection limit of 12.4 × 10-6 M without any interference effect of other nitroaromatic compounds. The plausible mechanism of PL quenching is considered as the inner filter effect, based on absorption, PL and PL lifetimes.
