We found that the levels of miR-21-5p and m6 A modification in the UUO model groups increased significantly, and as predicted, the SPRY1/ERK/NF-kB pathway was activated by miR-21-5p, confirming that miR-21-5p plays an important role in obstructive renal fibrosis by enhancing inflammation. METTL3 was found to play a major catalytic role in m6 A modification in UUO mice and drove obstructive renal fibrosis development by promoting miR-21-5p maturation. Our research is the first to demonstrate the role of the METTL3-m6 A-miR-21-5p-SPRY1/ERK/NF-kB axis in obstructive renal fibrosis and provides a deeper understanding of renal fibrosis.

The prevalence of sarcopenia and the health status of affected individuals, particularly among the young elderly, are unclear in Japan. We determined the prevalence of possible sarcopenia, a concept proposed by the Asian Working Group for Sarcopenia (AWGS) in 2019, and then investigated its clinical features in community-dwelling young elderly individuals in Kobe, a representative large city in Japan.

This retrospective cross-sectional study examined 1768 residents of Kobe aged 65 years who underwent health and frailty checkups implemented by Kobe City between April 2017 and March 2019. Possible sarcopenia was diagnosed by the AWGS 2019 algorithm. Frailty status was assessed with the use of the Kihon Checklist, which was developed to identify senior citizens requiring nursing care in Japan.

Fifty-one of the 1768 subjects were diagnosed with possible sarcopenia (overall prevalence of 2.9% [confidence interval 2.1-3.7%]), with the prevalence being higher in women than in men. Individuals with possible sarcopenia had a lower body mass index, abdominal circumference, diastolic blood pressure and percentage of taking lipid-lowering drugs as well as a higher high-density lipoprotein cholesterol level and estimated glomerular filtration rate. They also showed a higher degree of frailty. A low body mass index and physical inactivity were significantly associated with possible sarcopenia.

The prevalence of possible sarcopenia based on the AWGS 2019 criteria was 2.9% among 65-year-olds in Japan, with affected individuals more likely to be frail compared with those without this condition. Geriatr Gerontol Int 2021; 21 689-696.

The redbanded stink bug Piezodorus guildinii (Heteroptera Pentatomidae) is one of the most important species affecting soybean crops in southern South America. Capillary gas chromatography coupled to mass spectrometry was used to characterize the epicuticular hydrocarbon profiles of field-collected insects, and to identify differences in their composition between fifth-instar nymphs and adults, males and females, and between bugs collected in insecticide-treated and insecticide-free soybean crops.

Straight chain saturated n-C27 and n-C29, and monomethyl and dimethyl chains of C31 and C33 were the most abundant compounds. A group of volatile hydrocarbons with n-C13 and n-C15 as the predominant compounds were also detected. The hydrocarbon pattern was different between nymphs and adults, either males or females. Heneicosene was almost exclusively detected in adult males and was the most important component to differentiate between both sexes, followed by tricosadiene. The total hydrocarbon amount was significantly higher in nymphs, males and females collected in insecticide-treated fields compared with insects obtained from untreated fields.

Differences were found in the epicuticular hydrocarbon pattern among nymphs and adults, as well as sexual dimorphism in adult stink bugs. Interestingly, an alteration was also found in the hydrocarbon profile of insects collected in insecticide-treated soybean crops and its relevance is discussed within a pest management context.

Our aim was to assess the evolution and risk factors of AF after pLT. A retrospective single-center analysis of pLT patients with a follow-up of ≥5 years who underwent protocol liver biopsies at 6 months, 1 year, 2 years, 5 years, and 10 years was performed. Fibrosis was assessed using the METAVIR and Ishak systems and the liver allograft fibrosis score (LAFs). Of 219 pLTs performed from 2008 to 2018, 80 (36.5%) pLTs were included, and 320 biopsies were reviewed. At 6 months after pLT, fibrosis was found in 54 (67.5%) patients by the METAVIR/Ishak systems and in 59 (73.8%) by the LAFs (P = 0.65). By 5 years, AF was detected in 67 (83.8%), 69 (86.3%), and 72 (90%) specimens using the METAVIR, Ishak, and LAFs systems, respectively (P = 0.54); mild (METAVIR, 51 [63.8%]; Ishak, 60 [75%]; LAFs, 65 [81.2%]) and moderate (METAVIR, 16 [20%]; Ishak, 9 [11.9%]; LAFs, 7 [8.8%]) stages were detected, but severe ations. Donor selection, short CIT, and immunosuppression adherence are crucial to reducing the risk of advanced AF.In recent years, the repurposing of conventional and chemotherapeutic drugs is recognized as an alternative strategy for health care. The main purpose of this study is to strengthen the application of non-oncological drug metformin on breast cancer treatment in the perspective of epigenetics. In the present study, metformin was found to inhibit cell proliferation, promote apoptosis and induce cell cycle arrest in breast cancer cells at a dose-dependent manner. In addition, metformin treatment elevated acH3K9 abundance and decreased acH3K18 level. selleck screening library The expression of lncRNA MALAT1, HOTAIR, DICER1-AS1, LINC01121 and TUG1 was up-regulated by metformin treatment. In metformin-treated cells, MALAT1 knock-down increased the Bax/Bcl2 ratio and enhanced p21 but decreased cyclin B1 expression. The expression of Beclin1, VDAC1, LC3-II, CHOP and Bip was promoted in the cells received combinatorial treatment of metformin and MALAT1 knock-down. The reduced phosphorylation of c-Myc was further decreased in the metformin-treated cells in combination with MALAT1 knock-down than metformin treatment alone. Taken together, these results provide a promising repurposed strategy for metformin on cancer treatment by modulating epigenetic modifiers.

To investigate the long-term vasomotor response and inflammatory changes in Absorb bioresorbable vascular scaffold (BVS) and metallic drug-eluting stent (DES) implanted artery.

Clinical evidence has demonstrated that compared to DES, BVS is associated with higher rates of target lesion failure. However, it is not known whether the higher event rates observed with BVS are related to endothelial dysfunction or inflammation associated with polymer degradation.

Ten Absorb BVS and six Xience V DES were randomly implanted in the main coronaries of six nonatherosclerotic swine. At 4-years, vasomotor response was evaluated in vivo by quantitative coronary angiography response to intracoronary infusion of Ach and ex vivo by the biomechanical response to prostaglandin F2-α (PGF2-α), substance P and bradykinin and gene expression analysis.

Absorb BVS implanted arteries showed significantly restored vasoconstrictive responses after Ach compared to in-stent Xience V. The contractility of Absorb BVS treated segments induced by PGF2-α was significantly greater compared to Xience V treated segments and endothelial-dependent vasorelaxation was greater with Absorb BVS compared to Xience V. Gene expression analyses indicated the pro-inflammatory lymphotoxin-beta receptor (LTβR) signaling pathway was significantly upregulated in arteries treated with a metallic stent compared to Absorb BVS treated arterial segments.

At 4 years, arteries treated with Absorb BVS compared with Xience V, demonstrate significantly greater restoration of vasomotor responses. Genetic analysis suggests mechanobiologic reparation of Absorb BVS treated arteries at 4 years as opposed to Xience V treated vessels.

Such investigations can help to extend the application of DBA materials to opto-electrochemical devices and no longer limit them to optical physics research. In this work, a series of new DBA materials, TACzs, for overcoming this limitation are reported. All TACzs show strong intramolecular charge transfer (ICT) in their photoexcited states, leading to noticeable solvatochromism. Besides, the electronic structures of their radical anions show great variability, displaying different absorption spectra and diverse colors. Moreover, the potential application of TACzs as electrochromic and electro-fluorochromic materials are discussed. This work demonstrates that manipulating the π bridge between the donor and acceptor in the DBA system is an effective pathway not only to tailor the ICT properties of materials in their neutral state, but also to tune the absorption characteristics of their radical anion state, which makes them very promising for applications in electroluminescent and electrochemical devices.

Considering that patients on dialysis showed a poor outcome during COVID-19 pandemic, and that COVID-19 symptoms in dialysis patients are often mild or absent, each dialysis unit should implement local strategies to early recognize patients affected by COVID-19. However, many available SARS-CoV-2 diagnostic tests demonstrated a moderate sensitivity, 70%-80% is probably a reasonable estimate. Consequently, having useful tools for differential diagnosis becomes essential. In this scenario, lung ultrasound (LUS) may have an important role in the evaluation of lung involvement in hemodialysis patients during COVID-19 pandemic.

We present two cases of hemodialysis patients with COVID-19 pneumonia in whom LUS had a central role in the diagnostic process. Ultrasound images of COVID-19 pneumonia show a typical bilateral pattern characterized by multiple or confluent B-lines with spared areas, thickened and irregular pleural line, and rare subpleural consolidations. LUS showed high accuracy in diagnosing COVID-19 dialysis to present shortness of breath, fever, and multiple B-lines at LUS assessment (such as heart failure, fluid overload, vascular access infection, interstitial pneumonia) but the recognition of typical ultrasound patterns of the COVID-19 pneumonia is helpful for differential diagnosis. LUS may have an important role in the screening process of hemodialysis patients during the COVID-19 pandemic, especially in oligosymptomatic patients before the SARS-CoV-2 diagnostic tests, and in those with suspected symptoms and/or known exposure with unexpected negative SARS-CoV-2 diagnostic tests.
