Hepatitis C virus (HCV) infection is a major cause of chronic liver disease and associated cirrhosis, and hepatocellular carcinoma worldwide. At present, there is no prophylactic vaccine against HCV due to the lack of in vivo and in vitro model systems. Although most recombinants of all major HCV genotypes replicate in Huh-7 cell line and derivatives, these cells are human hepatoma-derived cell line. Therefore, the development of un-tumor-derived cell systems facilitating the entire HCV life cycle is urgently needed. In this study, we aimed to establish a novel tree shrew-derived bone marrow-derived mesenchymal stem cell (BM-MSC) system to reconstruct the HCV life cycle. We transduction cluster of differentiation 81 (CD81), occludin (OCLN), and microRNA-122 (miR-122) into BM-MSCs, then used a well-established HCV, produced from the J6/JFH1-Huh7.5.1 culture system, to infect the cells. We observed that BM-MSCs transduction with CD81/OCLN or CD81/OCLN/miR-122 support HCV RNA replication and infectious virus production. We also found that the addition of exogenous vascular endothelial growth factor (VEGF) can enhance HCV infectivity in BM-MSCs, with HCV virus load up to 105 copies/mL. In conclusion, we identified the minimum essential factors required for HCV replication in tree shrew-derived nonhuman nonhepatic BM-MSCs. Further, we identified that exogenous addition of VEGF, and exogenous expression of CD81, OCLN, and miR-122, facilitates efficient viral replication and production of infectious particles. Our results describe a novel cell system capable of supporting the entire HCV life cycle, which may provide an essential tool for anti-HCV drug discovery, vaccine development, and study of pathogenesis. © 2020 Wiley Periodicals, Inc.OBJECTIVES Evodiamine (Evo) possesses strong anti-inflammatory activity. In this study, we determine the antiarthritic effect of Evo. METHODS Evo was administered to rats with adjuvant-induced arthritis (AA). We evaluated arthritis symptoms & histopathological changes and measured inflammatory cell infiltration, pro-inflammatory cytokine production and Th17 & Treg percentages in arthritic rats. KEY FINDINGS Evo significantly improved the clinical signs of AA in rats, including decreases in paw swelling, the polyarthritis index and the number of swollen paw joints. Based on the histopathological analysis, Evo improved synovial inflammation and bone injury by inhibiting inflammatory cell infiltration, synoviocyte proliferation, pannus formation and cartilage erosion. Furthermore, the numbers of synovial CD3+ or CD68+ inflammatory cells were reduced, and the elevated levels of tumour necrosis factor-α, interleukin-1β (IL-1β) and IL-6 were restored to control levels by the Evo treatment. In addition, Evo therapy regulated the abnormal differentiation of Treg and Th17 cells, decreasing IL-17 production and increasing IL-10 levels. Finally, Evo inhibited Stat3 phosphorylation and induced Stat5 phosphorylation in rats with AA. CONCLUSIONS Based on our results, Evo is a promising antiarthritic agent, potentially due to its inhibitory effect on synovial inflammation and regulatory effects on Treg and Th17 differentiation. © 2020 Royal Pharmaceutical Society.Behavioral economic theory has proved useful for understanding the influence of delay and probability on sexual health decision-making. Demand is another principle at the intersection of microeconomics and psychology that has helped advance research relevant to health behaviors. The purpose of the present study was to develop and test a demand measure related to sexual health decision-making and the influence of sexually transmitted infection (STI) risk. Participants (N = 438) recruited using Amazon Mechanical Turk completed a commodity purchase task assessing hypothetical condom demand. Condom demand was evaluated at varied prices for use with hypothetical sexual partners that varied in STI risk. Demand was characterized by prototypic decreases in consumption with increases in cost. Higher partner STI risk was associated with greater intentions for condom-protected sex at no cost and smaller decreases in condom demand with increases in cost. Price sensitivity was also related to individual difference factors relevant to sexual health (e.g., alcohol use severity, lower STI knowledge). This study supports the utility of a condom purchase task for indexing condom valuation and capturing individual difference and contextual risk factors relevant to STI transmission. Future studies may leverage this methodology as a means to study sexual health decision-making. © 2020 Society for the Experimental Analysis of Behavior.INTRODUCTION The aim of this study was to investigate reasons why people consulted an occupational therapist following cancer treatment, and to examine the outcome of occupational therapy interventions, in the context of multidisciplinary rehabilitation. METHODS Data from 181 patients were collected retrospectively. The International Classification of Human Functioning and Health (ICF) was used to describe the reasons for occupational therapy consultation. Patients had completed the Canadian Occupational Performance Measurement (COPM) before and after the occupational therapy intervention. Change scores were calculated with a 95% confidence interval and a two-sided p-value obtained from a paired t-test. RESULTS The reasons for occupational therapy consultation were predominantly within the ICF domain "Activities and Participation". On average, patients improved 3.0 points (95% CI 2.8-3.2) on the performance scale of the COPM, and 3.4 points (95% CI 3.2-3.7) on the satisfaction scale (both p = less then .001). CONCLUSION The result of this study supports the added value of occupational therapy to cancer rehabilitation, and emphasise the positive effect of occupational therapy on everyday functioning. Controlled clinical studies are needed to strengthen the evidence. © 2020 Occupational Therapy Australia.PURPOSE Tattoo fiducials are commonly used in radiotherapy patient alignment, and recent studies have examined the use of UV-excited luminescent tattoo ink as a cosmetic substitute to make these visible under UV illumination. The goal of this study was to show how luminescent tattoo inks could be excited with MV radiation and imaged during beam delivery for direct visualization of field position. METHODS A survey of nine UV-sensitive tattoo inks with various emission spectra were investigated using both UV and MV excitation. Images of liquid solutions were collected under MV excitation using an intensified-CMOS imager. BAY 2927088 in vitro Solid skin-simulating phantoms were imaged with both surface-painted ink and in situ tattooing during dose delivery by both a clinical linear accelerator and cobalt-60 source. RESULTS The UV inks have peak fluorescence emission ranging from approximately 440 to 600 nm with lifetimes near 11-16 μs. The luminescence intensity is approximately 6x higher during the x-ray pulse than after the pulse, however, the signal-to-noise is only approximately twice as large.
