Monocyte-derived DCs (mDCs) are major target cells in porcine reproductive and respiratory syndrome virus (PRRSV) pathogenesis; however, the plasticity of mDCs in response to activation stimuli and PRRSV infection remains unstudied. In this study, we polarized mDCs, and applied genome-wide transcriptomic analysis and predicted protein-protein interaction networks to compare signature genes involved in mDCs activation and response to PRRSV infection. Porcine mDCs were polarized with mediators for 30 hours, then mock-infected, infected with PRRSV strain VR2332, or a highly pathogenic PRRSV strain (rJXwn06), for 5 h...

An economic selection index was developed for Beefmaster cattle in a general-purpose production system in which bulls are mated to a combination of heifers and mature cows, with resulting progeny retained as replacements or sold at weaning. National average prices from 2010 to 2014 were used to establish income and expenses for the system. Genetic parameters were obtained from the literature. Economic values were estimated by simulating 100,000 animals and approximating the partial derivatives of the profit function by perturbing traits 1 at a time, by 1 unit, while holding the other traits constant at their respective means...

The device performances of both n-type and p-type tunnel field-effect transistors (TFETs) made of single-layer InX (X = N, P, As, Sb) are theoretically evaluated through density functional theory (DFT) and ab initio simulations in this paper. It is found that a promising steep subthreshold swing (SS) of [less-than-or-eq] 60 mV dec(-1) can be obtained with gate length LG = 15.2 nm for all two-dimensional (2D) InX TFETs. In particular, an outstanding on-current of ∼1058 μA μm(-1) (or 880 μA μm(-1)) is estimated in a 2D p-type (or n-type) InSb device, which could barely satisfy the ITRS requirements for future high-performance (HP) applications...

BACKGROUND: Distinguishing sessile serrated adenomas/polyp (SSA/P), a subset of serrated polyps, from hyperplastic polyps (HPs) remains a challenge and has surveillance implications. Our goal was to identify clinical and pathologic factors associated with serrated polyps originally read as HPs being reassessed as SSA/Ps versus confirmed as HPs. METHODS: Data were collected from consecutive patients with a right-sided HP and a corresponding comparison group with conventional adenomas between 1993 and 2003...

Nitric oxide (NO)-releasing polymers have proven useful for improving the biocompatibility of in vivo glucose biosensors. Unfortunately, leaching of the NO donor from the polymer matrix remains a critical design flaw of NO-releasing membranes. Herein, a toolbox of NO-releasing silica nanoparticles (SNPs) was utilized to systematically evaluate SNP leaching from a diverse selection of biomedical-grade polyurethane sensor membranes. Glucose sensor analytical performance and NO-release kinetics from the sensor membranes were also evaluated as a function of particle and polyurethane (PU) chemistries...

Population variation in trophic niche is widespread among organisms and is of increasing interest given its role in both speciation and adaptation to changing environments. Trinidadian guppies (Poecilia reticulata) inhabiting stream reaches with different predation regimes have rapidly evolved divergent life history traits. Here, we investigated the effects of both predation and resource availability on guppy trophic niches by evaluating their gut contents, resource standing stocks, and δ(15)N and δ(13)C stable isotopes across five streams during the wet season...

Platelet counts increase after eradication of Helicobacter pylori (Hp) infection in non-pregnant patients with Hp-associated idiopathic thrombocytopenic purpura (ITP); however, improvement in pregnant patients has not yet been reported. We treated four pregnant women for Hp-positive ITP after Hp eradication. In three of four cases, platelet counts increased to levels exceeding 10 × 10(9) /L two weeks after eradication, and these levels were maintained until delivery. Vaginal deliveries were uncomplicated, and no excessive blood loss occurred in any of the cases...

Semi-synthetic biopolymer complex (SSBC) nanoparticles were investigated as a potential oral drug delivery system to enhance the bioavailability of a poorly water-soluble model drug acyclovir (ACV). The SSBCs were prepared from cross-linking of hydroxyl groups on hyaluronic acid (HA) with poly(acrylic acid) (PAA) resulting in ether linkages. Thereafter, conjugation of 2-hydroxypropyl-β-cyclodextrin (HP-β-CD) onto HA-PAA was accomplished using a 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC)/N-hydroxysuccinimide (NHS)-promoted coupling reaction...

Type 2 inflammation is a defining feature of infection with parasitic worms (helminths), as well as being responsible for widespread suffering in allergies. However, the precise mechanisms involved in T helper (Th) 2 polarization by dendritic cells (DCs) are currently unclear. We have identified a previously unrecognized role for type I IFN (IFN-I) in enabling this process. An IFN-I signature was evident in DCs responding to the helminth Schistosoma mansoni or the allergen house dust mite (HDM). Further, IFN-I signaling was required for optimal DC phenotypic activation in response to helminth antigen (Ag), and efficient migration to, and localization with, T cells in the draining lymph node (dLN)...

The pathogenesis of Rb1 gene inactivation indicates that gene therapy could be a promising treatment for retinoblastoma. An appropriate gene transfer system is the basis for successful gene therapy; however, little attention has been given to an effective gene transfer system for retinoblastoma therapy in previous studies. This study was designed to provide an optimized transgene system for WERI‑Rb1 cells (W-RBCs). Green fluorescent protein (GFP) was adopted as a reporter. Four classic viral vectors based on retroviruses, recombinant adeno-associated viruses (rAAV2, rAAV2/1), lentiviruses (LVs) and a novel non-viral vector X-treme HP reagent were adopted for W-RBC gene transfection...
