Guillain-Barré syndrome (GBS) is an immune-mediated peripheral neuropathy characterized by a typical post-infectious profile. Some post-Zika virus and post-severe acute respiratory syndrome-related coronavirus-2 GBS cases have been reported to occur with very short intervals between the infection and GBS onset. Evaluating 161 GBS patients consecutively admitted to two Italian Regional Hospitals between 2003 and 2019, we found that the only three with an antecedent influenza A (H1N1) virus infection developed GBS within an interval of less than 10 days from the influenza illness. The two of them with a demyelinating subtype promptly recovered without therapy. Overall, the parainfectious cases add heterogeneity to the GBS category, warranting pathogenetic insights.Placentitis is the leading cause of infectious abortion in the horse and contributes to roughly 19% of all abortions in the United States. A type of placental infection, nocardioform placentitis (NP) is associated with gram-positive branching actinomycetes localized within the ventral body of the feto-maternal interface to create a lymphoplasmacytic mucoid lesion. While the etiology of this disease is poorly described, this placental infection continues to cause episodic abortions in addition to weak and/or growth retarded neonates. The goal of the present study was to perform a comprehensive analysis of pregnancies associated with a nocardioform-affected placenta and make inferences into the epidemiology of this elusive disease. To do so, 264 mares were enrolled in the study, with 145 as having suspected disease (n = 145; NP) either based on pregnancy-related complications or postpartum placental evaluation, while an additional 119 were enrolled as healthy pregnancies (n = 119; CON). Following diagnosis as e, this did not appear to be influenced by the bacteria isolated (Amycolatopsis spp. vs. Crossiella equi), and mares diagnosed with NP do not appear to be infectious to other pregnant mares nor have repetitive years of the disease. Interestingly, lesion size was positively correlated with last breeding date, as mares bred later in the breeding season correlating with a larger placental lesion. In conclusion, while the etiology of NP continues to elude researchers, the epidemiology of this disease has gained clarity, providing inferences into the management of suspect mares.During an ovulatory follicular wave in the monovulatory species of heifers, mares, and women, the two largest follicles deviate in diameter at the end of a common follicle growth phase. The largest follicle before deviation becomes the future ovulatory follicle in most ovulatory waves. In 10-30% of the ovulatory waves, the destiny of the two follicles switches just before or at deviation so that the second-largest follicle becomes the future ovulatory follicle, and the largest follicle becomes a subordinate. In FSH-driven switching in heifers, mares, and women, the wave-stimulating FSH surge decreases to a low concentration before the largest follicle has developed the ability to utilize the low concentrations. The concentrations of FSH then increase (mares, women) or cease to decrease (heifers), and the next largest follicle acquires the capability of becoming the future ovulatory follicle. Luteolysis-driven switching has been reported in heifers but not in mares and women. The switching in heifers occurs duulatory follicle and CL in heifers is greater in three-wave IOI than in two-wave IOI. In summary, the second largest predeviation follicle becomes the postdeviation dominant follicle when the decreasing FSH is out of phase with the largest predeviation follicle in heifers, mares, and women or when luteolysis and predeviation are in synchrony in heifers.During implantation, the proliferation of trophectoderm cells (the outer epithelium of blastocysts) is related to conceptus elongation and placenta formation. Tryptophan (Trp) is a key regulator of embryogenesis and embryonic implantation during pregnancy. We sought to determine whether different concentrations of Trp alters porcine trophectoderm (pTr) cell proliferation. pTr cells were cultured in medium containing 40, 500, or 1000 μM Trp. The cell proliferation rate and the progression of the cells through the cell cycle were determined. To identify differentially expressed genes (DEGs) in the pTr cells, we compared mRNA transcriptomes by RNA-Seq after cell treatment with different concentrations of Trp. PHA-665752 Some candidate DEGs were identified by quantitative reverse transcription PCR (qPCR). High L-Trp levels (500 and 1000 μM) inhibited cell proliferation and induced cell cycle arrest. We identified 19 DEGs between the 500 μM L-Trp and 40 μM L-Trp groups and 168 DEGs between the 1000 μM L-Trp and 40 μM L-Trp groups and subsequently used qPCR to validate some genes that were upregulated or downregulated. The functional gene networks in which the DEGs were most enriched included those associated with regulating DNA replication and the cell cycle, and the majority of the DEGs in both of these functional pathways was downregulated. The results showed that the addition of 500 and 1000 μM Trp significantly increased the abundance of proteins in the Aryl Hydrocarbon Receptor (AHR) signaling pathway. Collectively, these results indicate a novel and important role for Trp in mediating the proliferation of porcine placental cells largely via the AHR signaling pathway. Additionally, these findings help to explain the side effects of excessive Trp supplementation on placenta development and embryo growth in mammals.Dermatopontin (DPT) is a small protein molecule thought to have a role in the formation of the extracellular architecture and adhesion. The aim of the study was to confirm the presence of DPT and to examine its role in placental cell adhesion during pregnancy, at parturition and postpartum in cows. Placental tissue samples were obtained at abattoir from healthy pregnant cows (n = 6) while parturient samples were collected during caesarian section and retrospectively divided into released up to 6 h (R; n = 5) and not released up to 6 h (NR; n = 4) foetal membranes. Maternal epithelial cells were isolated from pregnant samples and were used for the examination of the influence of DPT (5, 50 and 100 ng/mL) on cell adhesion. Parturient samples were manually divided into maternal and foetal part and individually homogenized for Western blotting and ELISA analysis. Western blotting confirmed the presence of DPT in examined tissues. ELISA test showed significant (p less then 0.05) decrease in DPT concentration within examined pregnancy period with higher concentrations in maternal part (p less then 0.
