To this end, we constructed a system in which the artificial transactivator was transcribed and amplified under the control of a heat-shock protein promoter, and introduced the system into the genome of Hepa/8F5 cells. In our modified cell line, heat-triggered LETF expression was confirmed to induce high liver function. After drug-screening of transfected cells, we established a hepatoma cell line (Hepa/HS), which exhibited high, heat-inducible liver functions. The Hepa/HS cells may represent a new cell source for hepatic studies such as the construction of BAL systems.

The liver is a main factory of UA production. In the present study, we have examined the effects of three kinds of flavonol and flavones as typical aglycons, i.e., quercetin, luteolin, apigenin, their glycosides and related compounds, on UA productivity in cultured hepatocytes, adopting allopurinol as the positive control drug. Quercetin, luteolin, diosmetin (4'-O-methylluteolin) and apigenin at 10, 30 and 100 μM as well as allopurinol at 0.1, 0.3 and 1 μM dose-dependently and significantly decreased UA production in the hepatocytes, when compared with 0 μM (control). Both rutin (quercetin-3-O-rutinoside) and quercitrin (quercetin-3-O-ramnoside) significantly reduced UA production in the hepatocytes at 100 μM. Luteolin glycosides such as orientin (luteolin-8-C-glucoside) and isoorientin (luteolin-6-C-glucoside) exerted no influences on it even at 100 μM. Likewise, apigenin glycosides such as vitexin (apigenin-8-C-glucoside) and isovitexin (apigenin-6-C-glucoside) showed no inhibitory effect on it, while apigetrin (apigenin-7-O-glucoside) significantly reduced it at 100 μM. In model mice with purine bodies-induced hyperuricemia, allopurinol completely suppressed the hyperuricemia at a dose of 10 mg/kg body weight. Rutin suppressed significantly the hyperuricemia at a dose of 300 mg/kg body weight, while vitexin showed no significant effect up to 300 mg/kg body weight. Thus, rutin (O-glycoside) is demonstrated to be hypouricemic in both cultured hepatocytes and model mice with recently contrived purine bodies-induced hyperuricemia.We found that strawberry extract suppressed immunoglobulin (Ig) E production in vitro and in vivo, and identified glyceraldehyde-3-phosphate dehydrogenase (GAPDH) as one of the IgE suppressor in the extract. We report here the effect of GAPDH on various Ig productions in vitro and in vivo. GAPDH suppressed IgE and enhanced IgA, IgG and IgM productions in ovalbumin (OVA)-stimulated human peripheral blood mononuclear cells. Oral administration of GAPDH at 10 mg/kg/day to OVA-induced allergy model mice tended to decrease total IgE level and increase total IgA and IgG levels in sera, and also decreased OVA-specific IgE and IgG levels. It is known that the increase of total IgA as well as the decrease of total and specific IgE is important for alleviating allergic symptoms. In addition, GAPDH accelerated IgA production and increased some cytokine secretions such as IL-4, TGF-β1 and IFN-γ in the OVA-immunized mice spleen lymphocytes. These cytokines involved in the class-switching, IgA enhancement, and IgE suppression, respectively, supporting above results. Our study suggests a possibility that oral administration of GAPDH may induce the immunomodulation in allergic responses.Chinese hamster ovary (CHO) cells are used as host cells for industrial monoclonal antibody (mAb) production. Cell cycle control is an effective approach to increase mAb production in the cell culture. Violacein, a purple-colored pigment produced by microorganisms, has diverse bioactive properties and has been proposed for various industrial applications. In this study, we evaluated the potency of violacein for cell cycle control and improvement of recombinant immunoglobulin G (IgG) production in CHO cells. Compared with the control, 0.9 μM violacein in a 14-day fed-batch culture increased the maximum IgG concentration by 37.6% via increasing the specific production rate and cell longevity. Cell cycle analysis showed that violacein induced G1 and G2/M phase arrest. However, the G1 arrest was observed only on day 1, while G2/M arrest lasted more than 3 days, suggesting that G2/M arrest mediated the violacein-induced enhanced IgG production. Moreover, in line with the increased protein expression, the expression levels of IgG mRNA and nutrient metabolic rates were also increased. N-Linked glycosylation and charge variant profiles were barely affected by violacein treatment. Navitoclax supplier Our results indicate that violacein affects the cell cycle of CHO cells and increases IgG production without changing product quality, showing promise as a mAb production enhancer in CHO cells. The study provides insight into violacein utilization in industrial mAb manufacturing and can help develop advanced, effective mAb production technologies using CHO cell cultures.Generative adversarial networks (GAN) are widely used in medical image analysis tasks, such as medical image segmentation and synthesis. In these works, adversarial learning is directly applied to the original supervised segmentation (synthesis) networks. The usage of adversarial learning is effective in improving visual perception performance since adversarial learning works as realistic regularization for supervised generators. However, the quantitative performance often cannot improve as much as the qualitative performance, and it can even become worse in some cases. In this paper, we explore how we can take better advantage of adversarial learning in supervised segmentation (synthesis) models and propose an adversarial confidence learning framework to better model these problems. We analyze the roles of discriminator in the classic GANs and compare them with those in supervised adversarial systems. Based on this analysis, we propose adversarial confidence learning, i.e., besides the adversarial learning ftes that adversarial confidence learning can both improve the visual perception performance and the quantitative performance.American Muslim intercommunal disunity (fitnah) is exemplified by an emic event when an editorial foray contests the inherited legacies of black Muslim icons like Malcolm X and Muhammad Ali, which exigently compels "diplomats" of different minds into engaging the digital public square with calculated strokes. The woke era's partisan identity politics asymmetrically curtail acceptable expressions of religious authority on issues of race, religion, and politics. Hence, scholars spend their social capital as political actors in these ultracrepidarian environments to different ends. This multi-year study conducted across global sites analyzes scholars with dissimilar approaches to media and political engagement amidst an environment characterized by weaponized media, polarization, and shifting goal posts. Participant observation and textual analysis impart scenes of scholars with fraught associations to administrations, funding sources, and feuding authoritarian Arab regimes getting embroiled in geopolitical hostilities. With mainstream American Muslim narratives aligned with mainstream media's liberal filter bubbles, scholars impact consensus building with varying levels of success; those negotiating compromise within spheres of legitimate contestation and consensus ad interim maintain subsisting influence. However, those that do not are expurgated and thereby cede influence.Farmers markets can offer solutions to several of the biggest problems besetting the US food system fair prices to farmers; healthy, fresh food for consumers; direct contacts between consumers and farmers; food for food deserts; support for local economies. Awareness of these benefits led us to study the farmers markets of Greater Cincinnati. Markets grew rapidly in the early 1980s, peaked in 2012, and declined 17% by 2018. Sixty-one percent of the markets that started since 1970 have closed. Two types of markets exist farmer-focused markets, with farmer vendors, and consumer-focused markets, with farmers and specialist vendors. Detailed information about market management shows that managers, the majority of whom are volunteers or underpaid, have insufficient resources to be sustainable. Market decline is often blamed on an oversupply of markets, but other factors are involved the inability of market personnel and customers to cross class and racial boundaries; the encroachment of online retailers; a scarcity of farmers; market manager failures. Individual markets need to form coalitions and gain sufficient resources from governments or private funders to employ specialists who can assist managers, expand the consumer base, and design promotion campaigns that effectively promote farmers markets in the changing retail food landscape.Meeting the demands of the Next Generation Science Standards requires that students engage in complex science texts. However, for many students, including students with disabilities, this can be a challenging activity. Many students lack the necessary skills and background knowledge to successfully engage with complex science texts. In this article we discuss how to use instructional scaffolds to address gaps and challenges in reading as a way to engage all learners in complex science text.
To investigate same day, previous day, and next day associations between trust, closeness, commitment, jealousy and provision of instrumental support with dating violence victimization and perpetration.
A convenience sample of young women, 16-19 years, in a heterosexual dating relationship with at least one act (past month) of physical or psychological victimization or perpetration, were recruited from urban public locations. Participants answered questions daily via text continuously for four months on dating violence and partner-specific emotions. Daily surveys asked about trust, closeness, commitment for their partner, jealousy, perceptions of partner's jealousy and provision of instrumental support to and from partner, and dating violence victimization and perpetration. Multilevel modeling examined within-relationship associations over time.
Mean (sd) age for the full sample was 18.1 (1.1) years. Same-day emotional context (trust, closeness, commitment, jealousy and provision of instrumental supporte surrounding episodes of dating violence. This granular understanding of the emotional context of dating violence has the potential to facilitate development of effective, developmentally appropriate interventions.This paper seeks to understand the association between ratees' relational justice perceptions and their feedback acceptance, both directly and through leader-member exchange (LMX). The paper also examines the moderated mediation effect of supervisory trust. The paper presents the findings of two studies. Study 1 utilized two data sets collected through an online survey from 280 part-time students working full-time (Sample 1) and 292 working professionals (Sample 2) in Pakistan. Study 2 utilized data collected from N = 167 students recruited for a scenario-based experiment that manipulated whether a manager was fair or unfair. Results revealed that relational justice positively predicted feedback acceptance in Studies 1 and 2. LMX positively mediated the above-mentioned relationship in both studies. As expected, supervisory trust negatively moderated the relational justice-feedback acceptance relationship in Study 2. The present study contributes to performance management theory and practice by illuminating that raters can stimulate performance partnership by employing a relational justice approach that increases the likelihood that employees accept performance feedback.
