Abstract A study was conducted examining the impact of feeding BioPlus 2B to PRRSV naïve sows during gestation and lactation on litter performance and on post-weaning performance when challenged with PRRSV in vaccinated and unvaccinated pigs. A total of 108 sows were allotted by parity and received a control diet (C) or BioPlus 2B (B2B) supplemented diet beginning a minimum of 31 d prior to farrowing through weaning. Pig weight was measured at birth and 17 d of age. At weaning, a subset of 200 pigs from each treatment were transported to a nursery and randomly allotted within dietary treatment

Abstract:

Porcine Reproductive and Respiratory Syndrome (PRRS) caused by the PRRS virus affects farmed pigs worldwide, causing direct and indirect losses. The most severe manifestations of PRRS infection are observed in piglets and pregnant sows. The clinical outcome of the infection depends on the PRRSV strain’s virulence, the pregnancy state of the female, environmental factors, the presence of protective antibodies due to previous infections, and the host’s genetic susceptibility. The latter aspect was investigated in this study, in particular, evaluating the most significant polymorphisms (SNPs) of

Abstract This sow study evaluated the effect that sugar beet pulp (SBP), a soluble fiber source, and a stimbiotic (Signis; AB Vista) can have on sow productivity and health when fed in gestation. A stimbiotic is an additive that stimulates fiber-degrading microbiome, resulting in an increase in fiber fermentability even though the additive itself contributes limited small chain fatty acid production. A commercial gestation barn with two feeding lines was utilized to feed sows (n = 2173) two dietary treatments from d 30 to d 90; a corn, soy, soy hulls with (HSDF) or without (LSDF) SBP (50 kg/t)

Abstract:

Porcine reproductive and respiratory syndrome viruses (PRRSV) are responsible for one of the most economically important diseases affecting the global pig industry. On-farm high-efficiency particulate air (HEPA) filtration systems can effectively reduce airborne transmission of PRRSV and the incidence of PRRS, but they are costly, and their adoption is limited. Therefore, there is a need for low-cost alternatives, such as antimicrobial filters impregnated with antiviral nanoparticles (AVNP).

Peptidoglycan recognition proteins (PGRPs) are a family of pattern recognition receptors (PRRs) involved in host antibacterial responses, and their functions have been characterized in most invertebrate and vertebrate animals. However, little information is available regarding the potential function of PGRPs in the giant triton snail Charonia tritonis. In this study, a short-type PGRP gene (termed Ct-PGRP-S1) was identified in C. tritonis. Ct-PGRP-S1 was predicted to contain several structural features known in PGRPs, including a typical PGRP domain (Amidase_2) and Src homology-3 (SH3) domain.

Abstract:

ABSTRACT The human herpesvirus entry mediator C (HveC), also known as the poliovirus receptor-related protein 1 (PRR1) and as nectin-1, allows the entry of herpes simplex virus type 1 (HSV-1) and HSV-2 into mammalian cells. The interaction of virus envelope glycoprotein D (gD) with such a receptor is an essential step in the process leading to membrane fusion. HveC is a member of the immunoglobulin (Ig) superfamily and contains three Ig-like domains in its extracellular portion. The gD binding site is located within the first Ig-like domain (V domain) of HveC. We generated a panel of monoclona

Abstract:

ABSTRACT One step in the process of herpes simplex virus (HSV) entry into cells is the binding of viral glycoprotein D (gD) to a cellular receptor. Human nectin-2 (also known as HveB and Prr2), a member of the immunoglobulin (Ig) superfamily, serves as a gD receptor for the entry of HSV-2, variant forms of HSV-1 that have amino acid substitutions at position 25 or 27 of gD (for example, HSV-1/Rid), and porcine pseudorabies virus (PRV). The gD binding region of nectin-2 is believed to be localized to the N-terminal variable-like (V) Ig domain. In order to identify specific amino acid sequences

Introduction Gastroenteropancreatic neuroendocrine tumours (GEP NET) are malignant neoplasms that impact survival. Somatostatin analogues (SSA) are used for treating hormonal symptoms caused by GEP NET and have antiproliferative effects. They are used as first-line therapy in patients with advanced GEP NET, but disease control is limited to a median progression-free survival (mPFS) of 14–32 months. Second-line treatment options include targeted therapy (everolimus or sunitinib), or peptide receptor radionuclide therapy (PRRT) with 177Lu-DOTATATE. In patients suffering from a NET-related hormon

They can occur anywhere in the GI tract with the small intestine, pancreas and rectum being the common GI sites. Because of nonspecific symptoms they are difficult to diagnose and diagnosis is often delayed by years. Advancement in cross-sectional imaging techniques and advent of radionuclide-labeled somatostatin analogs have improved our accuracy of diagnosis and staging GEP NETs. Endoscopic ultrasound (EUS) wi

Abstract INTRODUCTION ETV6-RUNX1 (ER), generated from translocation t(12;21), is the most frequent fusion gene in pediatric cancers, exclusively leading to B-Cell Precursor Acute Lymphoblastic Leukemia. Translocation occurs in fetal hematopoietic stem-progenitor cells (HSPC) but it is insufficient for disease. ER, in fact, is an aberrant transcription factor that expands a silent preleukemic clone with enhanced self-renewal and partial B cell differentiation. Secondary hits are thus required to complete transformation. Epidemiological and experimental data indicate that infections/inflammation

Currently, some MLVs are authorized for intradermal (ID) administration, which has many practical and welfare advantages.
