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. 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. read more © 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.INTRODUCTION To investigate the influence of tumor zonality on positive surgical margin (PSM) after Retzius-sparing robot-assisted radical prostatectomy (RS-RARP). MATERIALS AND METHODS Consecutive 203 patients with prostate cancer (PCa) who underwent RS-RARP in our center were divided into three cohorts according to the tumor zonal origin described on preoperative magnetic resonance imaging (MRI). Clinical and pathological characteristics were compared between the three groups. Relationship of clinicopathological parameters and PSM after RS-RARP was also evaluated. RESULTS The rates of PSM in men with transition zone and mixed tumors were significantly higher than that in patients with peripheral zone tumors (p less then 0.01). 42.0% and 40.9% of the positive margins in patients with transition zone and mixed cancers were located at the anterior part of the gland, respectively. On multivariate analysis, transition zone tumor was significantly associated with higher PSM rate after RS-RARP (p less then 0.01). Sub-analysis revealed that high risk patients with transition tumor had a higher risk of PSM after RS-RARP (p less then 0.01). CONCLUSION Transition zone tumor is an independent risk factor for PSM after RS-RARP. Preoperative identification of transition zone tumor might aid surgical planning with Retzius-sparing technique, especially for high risk patients. This article is protected by copyright.

Present study is therefore conducted to elaborate our understanding of differential age-wise response on growth, metabolic responses and fodder quality of Cenchrus ciliaris-3108 (Buffel grasses) to elevated UV-B (eUV-B; +7.2 kJ m-2 d-1 ). Plant growth at both the growth stages showed notable reductions except number of -nodes and -tillers at vegetative and reproductive stages, respectively. At the time of anthesis, the tillering increased due to perennial habit of plant but the defoliation of senesced leaves reduced the number of leaves per tiller. High ambient along with eUV-B at vegetative stage resulted in diversion of photosynthates for the formation of more secondary metabolites (tannins and phenolics) providing dual protection to plants from photooxidative damage due to high UV-B as well as from herbivory. The forage biomass as well as quality showed marked decline under eUV-B and relative nutritive value reduced at both the growth stages. This article is protected by copyright.

BMECs were isolated from Holstein cows (nonlactating, nonpregnant, and parous) and were stored by cryopreservation. To separate the apical and basolateral compartments, BMECs were cultured on a cell culture insert with a collagen gel in the presence of bovine pituitary extract and dexamethasone to induce milk production and tight junction (TJ) formation. The culture model showed the secretion of the major milk components, such as β-casein, lactose, and triglyceride, and formed less-permeable TJs in BMECs. Moreover, the TJs were distinctly separated from the apical and basolateral membranes. link2 Glucose transporter-1, which transports glucose into the cytoplasm through the basolateral membrane, localized in the lateral membrane of BMECs. Toll-like receptor-4, which binds to lipopolysaccharide in the alveolar lumen in mastitis, localized in the apical membrane. Beta-casein was mainly localized near the Golgi apparatus and the apical membrane. Moreover, milk components were almost secreted into the upper chamber of the cell culture insert. link3 These findings indicate that this model has clear cell polarity as well as in vivo and is effective to study of milk production and the blood-milk barrier in lactating BMECs. © 2020 Japanese Society of Animal Science.Skeletal reorganization is a type of fascinating transformations owing to their intriguing mechanisms and utility in complex molecule synthesis. However, these reactions are limitedly known for most functional groups. Herein, we describe such an unusual process of oxetanes. In the presence of In(OTf)3 as catalyst, oxetane-tethered anilines reacted unexpectedly to form 1,2-dihydroquinolines. This process not only provides expedient access to dihydroquinolines, but also represents a new reaction of oxetane. Mechanistically, it is believed that the reaction proceeds via initial nitrogen attack rather than arene attack followed by a series of bond cleavage and formation events. Control experiments provided important insights into the mechanism. © 2020 WILEY-VCH Verlag GmbH & Co.

In severe stages of this disease cutaneous sinus tracts may be observed. Platelet-rich fibrin (PRF) is a second-generation platelet concentrate used in medicine and dentistry for to promote tissue healing. This report describes the management of facial cutaneous sinus tracts secondary to MRONJ with autologous PRF injections. Eight patients with the diagnosis MRONJ and facial sinus tracts were enrolled in this study and received treatment. MRONJ lesions underwent pharmacological and surgical treatment. Sinus tracts received 1-mL injections of PRF around the fistula using an insulin syringe once a week for four times starting from the day of the surgical treatment. After 4 weeks, six patients showed healing of the fistula and bone lesions, only one patient showed healing of the fistula, and no remission was reported in another one. All patients reported an improvement of the symptoms in the first 2 days after the treatment session.
