Thus, pMP19 plays a role in the virulence of M. plutonius; however, its impact on the virulence varies among strains with different genetic backgrounds. This article is protected by copyright.

In July 2019, PRRSV-1 was detected in a PRRSV negative boar station, and subsequently spread to more than 38 herds that had received semen from the boar station. Selleck C59 Full genome sequencing revealed a sequence of 15.098 nucleotides. Phylogenetic analyses showed that the strain was a recombination between the Amervac strain (Unistrain PRRS vaccine; Hipra) and the 96V198 strain (Suvaxyn PRRS; Zoetis AH). The major parent was the 96V198 strain that spanned ORFs 1-2 and part of ORF 3 and the minor parent was the Amervac strain, which constituted the remaining part of the genome. The virus seems to be highly transmissible and has caused severe disease in infected herds despite a high level of genetic identity to the attenuated parent strains. The source of infection was presumable a neighboring farm situated 5.8 km from the boar station. This article is protected by copyright.

Very recently a great breakthrough was made by Tour and co-workers (Nature 2020, 577, 647-651) in just a second, easily exfoliated and highly crystalline graphene was produced from abundant carbon-containing species by cost-effective flash Joule heating with a low energy input of 7.2 kJ per gram graphene. Such an ultrafast, economic, and scalable process for high-quality graphene production can be considered as a milestone in the graphene field and is highlighted in this article. © 2020 Wiley-VCH Verlag GmbH & Co.

METHODS Retrospective cohort study of ITP patients presenting to the ED with severe thrombocytopenia (platelet count less then 20x109 /L) and bleeding in 4 academic hospitals from 2008 to 2016. We defined a major ITP bleed as a bleed at a critical site or causing hemodynamic instability. RESULTS We identified 112 ITP patients (n=141 visits) who presented to the ED with platelets less then 20x109 /L and bleeding. Twenty-nine patients (26%) had 32 ED visits with major bleeds. Risk factors for major bleeds were older age (odds ratio [OR] 1.03, 95% confidence interval [CI] 1.01-1.06), male sex (OR 3.25, 95% CI 1.22-9.32), and more prior ITP therapies (OR 1.42, 95% CI 1.10-1.87). Acute treatment of major bleeds required a median of 3 treatments (IQR 2-4), which included intravenous immune globulin (91% of visits), corticosteroids (78% of visits) and platelet transfusions (75% of visits). Three patients (10%) died, 9 (31%) developed recurrent bleeds, 1 (3%) developed arterial thrombosis and 1 (3%) had permanent neurological disability. Six patients presented with minor bleeding and subsequently developed a major bleed after a median of 2 days (IQR 1-3). All 6 patients had oral purpura and 4 of 6 had gross hematuria preceding the major bleed. CONCLUSIONS Major ITP bleeds are associated with significant morbidity and mortality. Oral purpura and hematuria often preceded major bleeds. Further research is needed to refine the definition of a major ITP bleed and develop evidence-based treatment strategies.

The findings were derived from people attending a single specialist service in Dar es Salaam for diabetic foot ulcers (DFUs) between 1 January 1999 and 31 December 2016. Details from people presenting for the first time with an ulcer judged to be caused by rat bite were compared with those with from other causes of foot ulcer. There were 426 first recorded foot ulcer episodes (in 179 people) judged to be caused by rat bite. The affected population was significantly younger (mean 55.9 vs 57.5 years, P = .037) and had a lower body mass index (26.5 vs 27.9, P = .008) than controls with other types of foot ulcer. They also presented significantly sooner (7.8 vs 18.2 days, P  less then  .001) and were more likely to heal (85.8 vs 5.5%, P  less then  .001), even though there was also a trend towards an increased risk of death (9.1% vs 5.3%, P = .032). Rat bite is an uncommon cause of DFU, but is not rare. Although the incidence of ulcer healing is higher than in a general foot ulcer population, the incidence of death is also higher. © 2020 Medicalhelplines.com Inc and John Wiley & Sons Ltd.This study investigated the effect of type-I interferon (IFN) on the expression of matrix metalloproteinases (MMPs) of the bovine endometrial stromal cells (BES) and epithelial cells (BEE). The cells were separated and purified from the caruncles and cultured in DMEM/F-12 containing 10% fetal bovine serum. Spheroids were generated by using ascorbate. Zymograms of the supernatant showed that BEE predominantly expressed MMP-9, whereas MMP-2 was expressed in BES and homo-spheroids. While MMPs expression was not detected in hetero-spheroids. Real-time quantitative PCR revealed that type-I IFN and P4 suppressed the gene expression of MMP-2 and MMP-9 in hetero-spheroids, respectively. On the other hand, gelatin zymography analysis of the supernatant showed that type-I IFN strongly promote the clearance of MMPs. While zymograms of the MMPs stocked in the hetero-spheroids were significantly reduced by type-I IFN. Phenylmethanesulfonyl fluoride and leupeptin (both are serine proteinase inhibitors) significantly repressed the clearance of MMP-2 and MMP-9 induced by type-I IFN. Moreover, collagen fibers in hetero-spheroids significantly decreased after the treatment with type-I IFN. In conclusion, it was suggested that type-I IFN participate in the tissue remodeling by regulation the clearance of MMPs. © 2020 Japanese Society of Animal Science.
