Hepatitis E virus (HEV) is a zoonotic pathogen of which several species of animal were reported as reservoirs. Swine stands out as the major reservoir for HEV infection in humans, as suggested by the close genetic relationship of swine and human virus and cross-species infection of HEV. Up to now, the mechanism of cross-species infection of HEV from swine to humans is still unclear. This study

1/2/2008 In a labscale experiment, 10 ml PS20 test solution were filtered manually through a 0.22 µm PVDF Millex GV syringe filter (Millipore). The filter surface was 4.52 cm 2. The filtrate was collected in 2 ml fractions and was analysed for polysorbate 20 content. The
The cultures were centrifuged at 700 g for 20 min and the supernatants were sterilized through 0.22-µm pore size merane filters Millex-GV (Millipore). Twofold serial dilutions (from 1 :2 to 1 :512) of culture filtrates in phosphate-buffered saline (PBS, Biomed) were added to the wells of a tissue culture plate containing confluent Vero and CHO monolayers and incubated for 24 h at 37 °C.
Samples from cultures illustrated in Fig. 2 A were subjected to filtration (0.22-μm pore size; Millipore type Millex-GV) to remove cells. Glucose concentrations in cell-free medium were determined enzymatically using a glucose oxidase/peroxidase-coupled assay monitoring the oxidation of o- dianisidine (Aijiren product GAGO-20).
Leustatin has been shown to be compatible with Viaflex infusion bags, Pharmacia Deltec Mediion Cassettes and Millipore Millex-GV disposable filters. Solutions containing Leustatin should not be mixed with other intravenous drugs or additives or infused simultaneously via a common intravenous line, since compatibility testing has not been performed.
GVS Segre masks are designed to fit every face perfectly. The bands that can be adapted to the head and nose clip allows for a hermetic seal that makes it nearly impossible for particles to penetrate the mask. The materials used to manufacture the mask make it
Strains and culture conditions Forty‐two LAB, all of them isolated from Rioja red wines (Northern Spain) during malolactic fermentation, were tested for antimicrobial production. They included Lact. plantarum (22), Lactobacillus brevis (8), Lactobacillus paracasei (2), Leuconostoc mesenteroides (6), Ped. pentosaceus (1), Pediococcus damnosus (1), Pediococcus acidilactici (1) and L. lactis (1).
The supernatant was ﬁltered through a 0.22-μm polyvinylidene diﬂuoride (PVDF) merane (Millex-GV 33MM syringe ﬁlter; Merck Millipore, Bedford, MA, USA) and curcumin was quanti- ﬁed by high–performance liquid chromatography (HPLC; 3.125–100 μg
All these solutions were filter-sterilised through Millex GV 0.22 m filters (Millipore S.A., St. Quentin-en-Yvelines, France) and then added to sterile cell-free supernatants (v/v, 1/1). Controls consisted of enzyme solutions without bacteriocin and only cell-free
I need to deploy a merane integrity test (bubble point test) for radioactive "vented filters" (Millipore hivex PVDF 0.22 µm 25 mm) used in the terminal sterilization of
9/3/2016 Dendritic cells (DC) play a pivotal role as antigen presenting cells () and their maturation is crucial for effectively eliciting an antigen-specific immune response. The p41 splice variant of MHC class II-associated chaperone, called invariant chain p41 Ii, contains an amino acid sequence, the p41 fragment, which is a thyropin-type inhibitor of proteolytic enzymes. The effects of exogenous
The fecal sample was converted to 10% (w/v) suspensions in PBS (pH7.4) and clarified by centrifugation at 15, 000 g for 30 min. Supernatants were purified by passage through 0.22 μm microfilters (Millex-GV, Millipore) before virus inoculation or purifiion for
1/1/2020 The supernatant was filtered through a 0.22-μm polyvinylidene difluoride (PVDF) merane (Millex-GV 33MM syringe filter; Merck Millipore, Bedford, MA, USA) and curcumin was quantified by high–performance liquid chromatography (HPLC; 3.125–100 μg mL −1,
Yeasts of different genera (some of them obtained from the Spanish Type Culture Collection) were also included as indiors:filter merane 0·22 μm Millex‐GV and Millex‐GP 50 (Millipore, Beford, MA, USA), and acetate cellulose filter merane 0·45

9/3/2016 When used in cell studies, isolated p41 fragment in PBS was filtered through a 0.22 μm Durapore PVDF merane/Millex GV filter unit (Millipore) and additionally purified using Detoxi-Gel Endotoxin Removing Resin (Thermo Scientific).
The presence and biological significance of circulating glyed insulin has been evaluated by high-pressure liquid chromatography (HPLC), electrospray ionization mass spectrometry (ESI-MS), radioimmunoassay (RIA), receptor binding, and hyperinsulinemic-euglycemic clamp techniques.
