2; and 11 (33.3%) cases had grade 3 histology. CONCLUSION The pattern of cancers in American Samoa differs from that in the US mainland. The findings reflect significant changes in cancer incidence. Cancer control programs should evaluate the potential of uterine screening in accordance with their community's needs and characteristics. This article is protected by copyright.

However, the regulatory mechanism of T4P and its relationship to bacterial virulence are still little understood in Xanthomonas oryzae pv. oryzae (Xoo), the causal pathogen of bacterial blight of rice. Our previous studies showed that the σ54 factor RpoN2 regulated bacterial virulence on rice in a flagellum-independent manner in Xoo. In this study, both yeast two-hybrid and pull-down assays revealed that RpoN2 directly and specifically interacted with PilRX, a homolog of the response regulator PilR of the two-component system PilS-PilR in the pilus gene cluster. Genomic sequence and reverse transcription PCR (RT-PCR) analysis showed 13 regulons containing 25 genes encoding T4P structural components and putative regulators. A consensus RpoN2-binding sequence GGN10 GC was identified in the promoter sequences of most T4P gene transcriptional units. Electrophoretic mobility shift assays confirmed the direct binding of RpoN2 to the promoter of the major pilin gene pilAX, the inner membrane platform protein gene pilCX, and pilRX. Promoter activity and quantitative RT-PCR assays demonstrated direct and indirect transcriptional regulation by RpoN2 of the T4P genes. In addition, individual deletions of pilAX, pilCX, and pilRX resulted in significantly reduced twitching and swimming motility, biofilm formation, and virulence in rice. Taken together, the findings from the current study suggest that the RpoN2-PilRX regulatory system controls bacterial motility and virulence by regulating T4P gene transcription in Xoo. © 2020 The Authors.

We hypothesize that BKV and CMV viremia infections decrease allograft survival in SPK. Identifying modifiable predictors of BKV and CMV may help tailor immunosuppression and improve allograft survival. METHODS All SPK recipients at our institution between January 2000 and April 2016 were included (n = 757). Thirty-nine recipients had BKV only and 25 had CMV only, and infection occurred at median follow-up times of 217 and 163 days, respectively. Event density sampling was used to match recipients with BKV or CMV to up to 10 recipients without infection by age, sex, and HLA mismatch status, and these were followed for a median of 4.3 years after infection. RESULTS Older age (HR 1.49 for each decade; 95% CI 0.95, 2.35; P = .083) and tacrolimus use (HR 20.6; 95% CI 2.37, 179.53; P = .006) were associated with increased incidence of BKV, but not CMV, infection. Both BKV and CMV infections were associated with increased risk of allograft failure for both pancreas (BKV [HR 2.17; 95% CI 1.47, 3.208; P = .000], CMV [HR 1.7; 95% CI 1.077, 2.687; P = .023]) and kidney (BKV [HR 2.65; 95% CI 1.765, 3.984; P = .000], CMV [HR 2.07; 95% CI 1.295, 3.308; P = .002]). CONCLUSION Older age at time of transplant and tacrolimus may help predict BKV infection in SPK recipients. © 2020 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.Fluid Catalytic Cracking (FCC) is an important process in oil refinery industry to produce gasoline and propylene. NSC-724772 Due to harsh reaction conditions, FCC catalysts are subject to deactivation through e.g. metal accumulation and zeolite framework collapse. Here, we perform a screening of the influence of metal poisons on the acidity and accessibility of an industrial FCC catalyst material using laboratory-based single particle characterization i.e., µ-XRF and fluorescence microscopy in combination with probe molecules. These methods have been performed on density-separated FCC catalyst fractions, allowing to determine interparticle heterogeneities in the catalyst under study. It was found that with increasing catalyst density and metal content, the acidity and accessibility of the catalyst particles decreased, while their distribution narrowed with catalyst age. For example, particles containing high Ni level possessed very low acidity and were hardly accessible by a Nile Blue dye. Single catalyst particle mapping identifies minority species like the presence of a phosphated zeolite ZSM-5-containing FCC additive for selective propylene formation, catalyst particles without any zeolite phase and catalyst particles, which act as a trap for SOx. © 2020 WILEY-VCH Verlag GmbH & Co.

METHODS An evaluation study was conducted at 67 basic- and comprehensive-level health facilities serving the poorest areas in Honduras, Nicaragua, and Belize. Cases of severe pre-eclampsia or eclampsia were randomly sampled and relevant quality of care data extracted from medical records at baseline (n=111) from January 1, 2011, to March 31, 2013, and at second-phase follow-up (n=249) from June 1, 2015, to September 30, 2017. The primary outcome was evidence of the delivery of multidimensional care for the management of pre-eclampsia/eclampsia. RESULTS The care of 360 women with severe pre-eclampsia or eclampsia was analyzed. Odds of multidimensional care for pre-eclampsia management (P=0.271) increased (although not significantly) in the second-phase follow-up compared to baseline. Multidimensional care was significantly associated with training (P less then 0.001), basic-level facilities (P less then 0.001), and higher in Honduras (P=0.001) and Belize (P=0.024) than the reference country of Nicaragua. CONCLUSION Multidimensional care for pre-eclampsia management increased across all facility types, countries, and severity of disease. The Salud Mesoamérica Initiative is a promising model for achieving such quality of care interventions in the era of universal health coverage. This article is protected by copyright.
