AIMS Presentation of acute events in patients with atherosclerosis remains unpredictable even after controlling for classical risk factors. MicroRNAs (miRNAs) measured in liquid biopsies could be good candidate biomarkers to improve risk prediction. Here, we hypothesized that miRNAs could predict atherosclerotic plaque progression and clinical event presentation in familial hypercholesterolemia (FH) patients. METHODS AND RESULTS Circulating miRNAs (plasma, exosomes, microvesicles) were investigated by TaqMan Array and RT-qPCR assays. Patients with genetic diagnosis of FH and healthy relatives from the SAFEHEART cohort were included. A differential signature of 10 miRNA was obtained by comparing two extreme phenotypes consisting of FH-patients suffering a cardiovascular event (CVE) within a 8-year follow-up period (FH-CVE, N=42) and non-FH hypercholesterolemic relatives from the same cohort, matched for age and treatment, without CVE during the same period (nFH-nCVE, N=30). The validation studies included two rdiology. All rights reserved. © The Author(s) 2020.

Prognosis largely depends on disease stage, with 5-year melanoma-specific survival ranging from as high as 99% in patients with stage I disease to less than 10% for some patients with stage IV (distant metastatic) disease. Fortunately, in the last 5-10 years, there have been remarkable treatment advances for patients with high-risk resectable melanoma, including approval of targeted and immune checkpoint blockade therapies. Salinomycin datasheet In addition, results of recent clinical trials have confirmed the importance of sentinel lymph node biopsy and continue to refine the approach to regional lymph node basin management. Lastly, the melanoma staging system was revised in the eighth edition AJCC Cancer Staging Manual, which was implemented on January 1, 2018. Here we discuss these changes and the clinicopathological features that confer high risk for locoregional and distant disease relapse and poor survival. Implications regarding the management of melanoma in the metastatic and adjuvant settings are discussed, as are future directions for neoadjuvant therapies. © The Author(s) 2020.

Nonadherence can negatively affect the trial sample size and estimation of the treatment effect. This protocol aims to evaluate the effects of a telephone call reminder on the adherence rates of participants to interventions in a cardiovascular randomized trial. This is a study within a trial (SWAT). The host trial is evaluating the effectiveness of a multidisciplinary 16-wk cardiovascular disease prevention program on risk factor profile among patients with carotid artery stenosis. Simultaneously, this SWAT will evaluate the effectiveness of telephone call reminders on the participants' adherence to the host trial intervention. The primary outcome is adherence to the protocol of the host trial. Secondary outcomes are level of adherence, number of dropouts, and time to drop out from the host trial. © 2020 Chinese Cochrane Center, West China Hospital of Sichuan University and John Wiley & Sons Australia, Ltd.Porphyrin metal-organic frameworks (PMOFs) are emerging as heterogeneous photocatalysts owing to the well-designed frameworks incorporated with powerful light-harvesting porphyrin chromophores. The porous and stable framework Ir-PCN-224 (which is also denoted as Ir-PMOF-1), which has been prepared by the self-assembly of Ir(TCPP)Cl (TCPP=tetrakis(4-carboxyphenyl)porphyrin) and ZrCl4 , is reported herein to be efficient for the aerobic cross-dehydrogenative carbon-phosphorus coupling reaction, giving rise to a high turn-over number (TON) of up to 17200 under visible light irradiation (λ≥420 nm). Electron paramagnetic resonance (EPR) experiments disclose that the active species might be the superoxide radical anion (O2 .- ). Additionally, the intermediate imine cation has been detected by high-resolution mass spectrometry (HRMS). © 2020 Wiley-VCH Verlag GmbH & Co.

Although a few genes have been characterized to regulate tiller angle in rice, the molecular mechanism underlying the control of tiller angle via microRNA is poorly understood. Here, we report that rice tiller angle is controlled by OsmiR167a-targeted auxin response factors OsARF12, OsARF17 and OsARF25. In the overexpression of OsMIR167a plants, the expression of OsARF12, OsARF17 and OsARF25 was severely repressed and displayed larger tiller angle as well as the osarf12/osarf17 and osarf12/ osarf25 plants. In addition, those plants showed compromised abnormal auxin distribution and less sensitive to gravity. We also demonstrate that OsARF12, OsARF17 and OsARF25 function redundantly and might be involved in HSFA2D and LAZY1-dependent asymmetric auxin distribution pathway to control rice tiller angle. Our results reveal that OsmiR167a represses its targets, OsARF12, OsARF17 and OsARF25, to control rice tiller angle by fine-tuning auxin asymmetric distribution in shoots. © 2020 The Authors.

We now show that Orf306-dependent metabolic remodeling is due to regulation of a novel small RNA (sRNA). Endogenous propionate, produced due to the esterase/lipase activity of Orf306, repressed expression of a novel E. coli sRNA, co293. This sRNA post-transcriptionally regulates expression of the transcription factors HcaR and FadR either by inhibiting translation or by destabilizing their transcripts. Hence, repression of co293 expression elevates the levels of HcaR and FadR with consequent activation of alternative carbon catabolic pathways. HcaR activates the hca and MHP operons leading to upregulation of the phenyl propionate and hydroxy phenyl propionate (HPP) degradation pathways. Similarly, FadR stimulates the expression of the transcription factor IclR which negatively regulates the glyoxylate bypass pathway genes, aceBAK.
